Why Gas Engines Are Far From Dead - Biggest EV Problems

[@EngineeringExplained]

*WATCH PART 2 AFTER!* It includes an efficiency discussion: kzbin.info/www/bejne/pXuvaoCXqKd5rK8 *IMPORTANT NOTE:* Obviously, I should have discussed efficiency, as I have in almost every video where I discuss EVs. EVs are often 3-4x as energy efficient, meaning you need *less* energy total to move a certain distance (compared to the very best diesels, they're about 2x as efficient). That's why a "3 gallon" tank Tesla can drive 350 miles. Again, as mentioned in the video, the sweet spot right now is EV passenger cars. When you talk about towing, freight trucks, trains, planes, etc, the weight gain is not offset by the efficiency gain. Don't believe me? Here's the math: kzbin.info/www/bejne/iWW6XoNrlqiKgNU *UPDATE TWO:* I hope no one interprets this video as electric cars aren't cleaner/more efficient/better for the environment. They most certainly are: kzbin.info/www/bejne/bIPLpZyGmsuJsK8. Also an important consideration if you're in the market for an EV is buying the range that you need. A smaller battery has a significantly lower impact than larger batteries, and will offset its carbon footprint much faster. Obviously, this will result in lower range (city commuting, multi-car family, etc).

Engineering Explained Question about towing: Why an EV car is efficient in towing the first 2 tons (its own weight), but not efficient in towing the second 2 tons (the trailer). I’m sure I missed something, I just don’t know what.

[@exparrot9074]

Hey Jason, any chance you can do a video on Mazda's recent claim with the MX30 that for total life cycle emissions they chose to go with a shorter range smaller battery pack? They also state that if they were to go with a larger battery pack their life cycle emissions would be greater then an equivalent diesel. I would like to see if you can back out the assumptions that they use. On another note, I do not believe current or gradual improvements of Lithium Ion batteries are going to be suited to constant high load applications when there is a weight restriction (i.e towing and vehicle weight class regulations or as you started to get into - aircraft). We have not been seeing the industry get the specific energy high enough, fast enough, to even come close to matching the performance of liquid fuel powered vehicles, even if they are less energy efficient.

You missed a few points: 1. Engine efficiency: The electric engine is much more efficient than the combustion engine, that means you need at least twice as much energy from the gasoline than from a battery. 2. Charging time: Filling a tank with gasoline takes less than 5 minutes wherever you are. Charging the battery takes forever, no reason to stop smoking ;) 3. Electricity Grid Capacity: Assume you try to replace 50% of the cars by EVs, the grid would break down long before reaching that. 4. Emissions: Just because you do not see and do not smell the emissions of an EV doesn't mean they are not there. Producing and recycling EVs is much dirtier, and also the electricity needed has to be produced somewhere and causes pollution. Some calculations showed that you have to drive over 100'000km until the emissions are equal, and much more to be more clean. 5. Safety: If a car with combustion engine is burning the fire is easy to put out. If a battery is burning it will burn for a long time no matter what you do. There are of course battery technologies that are more safe but also heavier.

Another thing about the weight of gasoline and that of ion-lithium batteries: As you drive, gas leaves the car in the form of exhaust. Once you have used the energy in the gas, you aren't carrying the weight of it around. With the batteries, you still are transporting the entire weight of the expended energy source, progressively losing energy but not the load it moves. Probably not a big difference, but a difference never the less.

[@roteroktober360]

And then there's mining costs, the cost to mine the materials for battery consumes a lot more energy and pollution than just burning gasoline or even better, LNG. Then there's no good way of recycling batteries, yet. And then there's battery degradation, there are many countries in Europe and Asia where people don't use cars all that often. They just use public transport, which is more time efficient because of just how dense those cities are. If all of them had electric cars, the batteries would just be sitting around for the most part doing nothing. So if you don't use the electric car as much, on balance, it is more polluting vehicle compared to a gasoline vehicle. Electric cars only realistically have savings in net pollution when they cross a high mileage compared to gasoline vehicle.

This is a common misconception. People almost always charge at night. Utilities need a ton more power during the day - and have generation capacity to spare at night. Using EV's improves resource utilization of that capacity and utilities **LOVE** that. Evidence of this is that almost every electric company in the USA offers cheap rate nighttime electricity as a deal for higher rate daytime usage. They do this to try to spread the load of dishwashers, washer/driers, etc. They **LOVE** EV's. Also if Elon Musk waved a magic wand and turned every car and light truck in the USA into an electric vehicle overnight - the total US electricity consumption would increase by about 15% - well within even our daytime capacity limits. But also, the shipping and refining of oil into gasoline and diesel consumes a MOUNTAIN of electricity...which is saved when people switch to EV's.

[@SteveBakerIsHere]

​@@holdmybeer123 The raw materials production costs for an EV are less than for a gasoline vehicle. Remember - no engine, no radiator, no hoses, no transmission, no oil pump, no fuel tank, no fuel pump, no air filter, no water pump, no starter motor, no generator, no exhaust system, no catalytic converter...EV's are *very* simple machines. Also, there are VERY good ways to recycle batteries. Tesla have built a battery recycling plant right next to their battery production system so the materials from old batteries are recycled directly into new batteries...in the same building! Toyota have been efficiently recycling Prius batteries for about the last 15 years. This isn't rocket science. Reclaiming old batteries is easy (Tesla actually pays the scrapyards to remove them) - and recycled materials are cheaper than mining new materials - so it's a no-brainer. Battery degradation is a S-L-O-W process on a modern EV. A Tesla battery is currently lasts at least 600,000 miles - about three times the life of a gasoline car...and their next-gen battery will last a million miles. Degradation was a problem with the older EV's like the Nissan Leaf - which didn't have battery thermal management - but that lesson has been learned and battery degradation is not a problem anymore. You claim that under-used electric cars don't save on pollution isn't based on reality...I don't know where you get that from but it's definitely not true. With a gasoline car, there is a problem that if you don't use it enough, the gasoline will go bad and it'll be hard to start and have terrible MPG. This doesn't happen with an EV.

[@excalibur4332]

As an electrical engineer, I can assure you that as batteries become more compact, the increased energy per volume will simply make the battery that much more dangerous to breakdown, outgassing, and explosive decomposition. In fact, the risk of fire will far surpass that of gasoline per volume. This is not a simple issue.

[@Alex-bl8uh]

Though questioning people for purchasing phones, EV's or literally any other Lithium-Ion battery driven piece of technology is the wrong place to put your ire. The truth is that many of the industries behind the development of the electronics and convenient objects that we use in our daily lives have truly corrupt methods to cheaply mine, create and develop these objects. We definitely 100% need to stop taking cheap shortcuts, exploiting human rights and leveling everything that we can in nature to just consume. We also need to put focus into recycling the materials that can be used more than a single time or in some other product that is also useful. I am also quite aware of the fact that in 2016, the usage of Cobalt in Lithium-Ion batteries was ~20% globally in early EV batteries, telephone batteries and all other electronic devices using Lithium-Ion technology. In 2020 the use of Cobalt jumped to over 60% globally in no small part due to the increased demand for EV batteries. This will continue to increase as we demand more and more EV's, telephones and digital devices using Lithium-Ion battery technology. We need to ensure that the mining and production of these technologies follows proper industry standards and does not continue to exploit cheap labor forces forced into horrible working conditions. This is a problem that needs to be handled, but the our anger needs to be directed to our local government representatives. No, I did not buy my PHEV because I thought that it would be a cute idea and make me cooler or better than others around me in some way. I bought a PHEV to reduce my CO2 and Carbon Monoxide footprint when I drive in my city, which is always full of start and stop traffic. Because Carbon monoxide emissions, unburned hydrocarbon emissions, nitrogen oxide emissions and carcinogenic particles from I.C.E. vehicles kill a large amount of people in our cities each year and the air quality in our cities is important to me. I live in a large urban center, and while I drive in EV mode I am not creating any of these toxic emissions. I also live in a country which produces over 60% of its energy using clean energy options, so charging does begin to make sense. I also chose to buy a PHEV vehicle with one of the smallest Lithium-Ion battery units possible while still getting the range that I actually need. My battery is an 8.8 KWh battery and it allows me to drive without using any petrol in the city. Am I right to have made this choice? I cannot really say tbh, but I am trying to promote cleaner approaches and maybe to optimistically hope that the industries behind them will also be held to better standards as we move forward.

Good video. Love the practical, common item examples. One point that should be made is the gasoline engines have around a maximum 33% efficiency converting the latent energy of gasoline into mechanical energy, while electric motor and their required variable frequency drive partners have efficiencies in the mid-90% range. ICE engine powertrains also have transmissions and axles/differentials that are mid-90% efficiency while the electric powertrain has a single speed gearbox/differential operating in the high-90% zone. Doing algebra with a lot of rounding, we end up with ICE powertrains at 30% and electric powertrains at 75%. This means you need to take more than half the LaCroix cans off the table because it is a 2.5:1 ratio for the energy that actually gets to the road. Now, that is only in the car. Electrical energy still has to be made and those processes are incredibly inefficient and usually polluting. Even the best solar panels are only 25-30% efficient when new and are made from “interesting”materials. I’m all for electric but it is certainly not an easy slam dunk.

If you redo the math considering parallel serial hybrids with engines with 40% efficiency (Toyotas that today cost as roughly much as regular cars) and the fact that on the other side of an EV usually sits a GE gas powered 60% efficient turbine (or worst, here in the US), you may conclude hybrids are better deal, at least for the next 20 years or so.

[@davidwebb2318]

Don't forget that your power station is only 50% efficient. The grid transmission loses 8-12% of the electricity and then EVs lose another 40% (they are 60% wall to wheel efficient). Modern petrol and diesel engines are 37%-43% efficient. Multiply out the EV numbers above and you will see that EVs are actually less efficient at converting fuel to motion than a petrol or diesel car. As 60% of electricity in the US comes from fossil fuels it would actually use less fuel resources if people bought new petrol or diesel cars instead of EVs. Most people have fallen for the idea that EVs are more fuel efficient but they haven't actually worked out the numbers. EVs are cheaper to run because there is less tax charged on electricity than gasoline. People therefore assume they must be more efficient but it isn't really true.

For anyone wondering why fuel has so much more energy density than batteries: Fuel requires oxygen, which isnt stored in the car. By being able to take in oxygen along the way without storing it significantly reduces the mass that needs to be transported. In order to burn 1kg of octane it takes over 2kg of oxygen. While this doesnt account for everything, it makes it much trickier for any alternative energy storage technology to be taken seriously.

3:00 Something he forget to mention is that IC engines have efficiency of 20%-25% while EVs have efficiency of 85%-95%. So, while you can still carry more energy per volume with gasoline, in the real-world value is closer to 4 times rather than 13. As for the batteries-only-for-personal-vehicles argument: the mining industry have been electrifying for decades and in EU BEV long haul trucks are on the rise. A BEV semi truck saves €50 000 - €70 000 a year in diesel costs alone (a back-on-the-napkin calculation). BEV trains are also in development in many places as replacement of diesel one on non-electrified tracks. While airplanes are indeed not suited for battery power, many if not all other type of transport can be electrified, making it cheaper to run in the process. While R&D in ICE shouldn't stop, it's really annoying to see the old car manufacturers making up excuses just because they already have the people and facilities in place of ICE

You can't just turn a boiler on or off on demand. It takes hours to bring one online, and it takes hours to safely bring them offline. So they're great for __stable__ baseline load needs, assuming you're otherwise in compliance with other environmental regulations. But reality is, that natural gas burns more cleanly than most forms of coal. Which makes environmental compliance costs for emission abatement lower, in addition to being much easier to transport as either a liquid or gas rather than in a solid such as is the case with Coal. This also isn't to mention the coal-ash problems, and a slew of other solid and liquid waste issues specific to coal. Meanwhile, the newest Natural Gas Power plants are turbine plants, not boilers, and they can be brought online quickly and easily when the green power sources aren't producing, and can be easily taken offline when the green power sources are producing. Something that cannot be done with a boiler. Nuclear Power is experiencing a comparable because it also operates as a boiler plant, they take hours to bring up to full power, and hours to bring offline. It doesn't lend itself well to the "spiky" power grid that large scale Wind and Solar operations often introduce into a power grid.

Then the chemical energy is converted to electrical energy to drive the motor.

As someone with a chemistry degree, I find it very hard to get others to grasp the concept of energy density and all the problems with switching fuels. Your hands-on demo did a great job of that. One thing I like to do is take their car's MPG value and determine how much gasoline it takes to move it 1 mile. They are usually shocked when they find out how little it takes - usually a couple ounces (vol). Then compare that with a battery or other fuel and they start to understand how lucky we are to have such an energy-dense fuel like gasoline. As a cherry, you can calculate the mass moved per teaspoon of gasoline (by using the weight of the car). That's also a shocker value when they hear it. In any event, great video.

[@ScienceNotFaith]

@John and Sasha Davis The point/goal isn't to turn others into scientists but to get them to grasp the concepts. If I build a vehicle that weighs 1 ton as an example. Then I design a system to power it, the energy density of one fuel might mean adding an additional ton just for the propulsion, with another it might be more or less (depending on the fuel). That all makes a difference in cost to build, to power it, and maintenance (due to parts and complexity). So just saying one fuel is better than the other isn't meaningful unless you understand how beneficial it is in saving weight/power supplied. Nobody is asking consumers to memorize numbers.

[@roytee3127]

Sure - driving along a straight flat road at 55 mph with no acceleration doesn't take much gasoline. That was the original idea behind small-engine hybrid cars. But accelerations, uphill climbs are another matter entirely. My ICE car's MPG gauge drops way, way down when I step on the accelerator. And all that energy gets wasted as heat when I step on the brakes.

[@MikeDeeee]

@@RafaBezowski Depends of course on your driving style and the car, but 25-30 kWh for 60 miles is really very high. For my commute, I need around 15 kWh (+10% charging losses) for 80 miles (mostly motorway at 90 to 100 km/h but some city driving as well). For the same 80 miles at the same speed, I used approximately 6 litres of diesel with my previous car, or 60 kWh of energy content.

However, I do agree the number one shortfall of the EV right now is range for the amount of time to charge. This could be resolved if the infrastructure supported a battery swap system, but that probably won't occur until the few last drops of gasoline sputter from an ICE.

Very well said. The only thing I think you could have also mentioned is that there is a huge efficiency loss with the weight of the fuel source itself being less dense. Same problem rockets have.

Hydrogen is a dead-end.

This "chicken and egg" problem is fundamental. Also, hydrogen costs around four times as much per mile as gasoline and twelve times as much as electricity - so it's HIDEOUSLY more expensive. The cars also cost about twice what an electric car costs - and that's with Toyota selling them at a massive loss. Also, current hydrogen production uses fossil fuels and produces considerably more CO2 than a gasoline car. Japan has quite a few hydrogen cars - but it's a VERY tiny country (in terms of square miles) - so it's not hard to build enough filling stations. But Japan buys hydrogen from Australia - which makes it using the nastiest fossil fuel out there ("brown coal"). So (in effect) Japan causes a LOT of CO2 pollution - but can blame it on Australia. Hopefully, Australia will do something about that - and then Japanese hydrogen car owners are screwed.

The reason for this is because electric cars are FAR more efficient at utilizing energy, plus electricity is far cheaper than Gas. As an example, depending on your state that 300 miles of range cost between $10 to $20 in a Tesla, while the average for a car is around $35 to $50, depending on the type of gas needed and the price in your area.

[@brrebrresen1367]

solid state batteries will be the future but there still be an other obstacle in the way that need to be fixed. first they have to get out of early prototype as they are in now, second is 1000 miles range and 15min charge time will need extreme upgrades of the charging infrastructure, combined with very high voltages, ampere and exotic cooling. even today's fast charging cars need liquid cooling of the charger to not make em burst into flames now think 5 to 20 times that power. combine that with that some of the charging station companies take very high premium per kWh for the fast chargers up towards so high that it makes it cheaper to run gasoline even here in Norway where we pay around 2$ per liter of standard 95... (Tesla is going away from the "free" charging and disables it on second-hand cars) so if you have the time and can charge at home the slow way with an 10 or 16A line EV's are great. though while classic gasoline engine's got low efficiency but there is tech on the way and some "early versions" of it on the road already that makes the "just 20%" look silly. Mazda got the HCCI engines to work though with a little cheat in the form of the SPCCI, problem is that they don't like low or high rpm's when running in pure HCCI mode when they can reach as high as close to 70% efficiency atm.... however atm there is no car yet that then utilise that in what would been the best form, a hybrid system ala Fisker Karma and Opel Ampera as a pure range-extender always running on the most optimal rpm. so ICE isn't dead yet, but soon it might be as the pure solution for movement.

[@darrylwbraun]

@Akashic Samadhi hanging your hopes on hypothetical advances in technology is not a sound practice. Sure these batteries MAY show up, but so far they are the ever promised, never delivered dreamware of engineers. I agree, WHEN they show up, things are going to change and ICE cars and trucks will be obsolete. WHEN they show up. It's just as fair to say "when the transporter shows up ALL vehicles will be obsolete". Yes, graphene batteries are more realistic, but they're still just dreamware at this point.

[@johnnyappleseedgate2232]

Yes, the average cost for ICE vehicle is so high because....35% to 50% of that $35-$50 is a tax that pays for road maintenance. This is why places that have had lots of drivers switch to EVs have started rolling back the subsidies and increasing the taxes. Switch away from ICE vehicles and you'll notice an increase in electricity prices to make up for the lost fuel taxes.

@Akashic Samadhi Half the planet still burns coal at 25% to generate that electricity.

[@roji556]

Akashic Samadhi Batteries also don’t function close to the same when it’s either very hot or more importantly, when it’s very cold and quickly lose efficiency. ICE vehicles have similar efficiency and performance in all conditions. You’re also forgetting that most of the electricity you put in to your car is generated by non-renewable sources meaning that you’re still not doing well for the environment.

[@trevork3669]

There is some error in your energy density comparison representation - you show that a Tesla battery can only hold the energy equivalent of 3 gallons of gas. If your math & sources are correct (which I expect they are), there must be some additional variables (such as the energy that is wasted into heat, or how completely the fuel is burned) which are relevant to the discussion - how efficient the engine/motor can translate that energy into work matters. (Which is why a Tesla can travel more than ~90 miles even without regenerative braking despite only having ~3 gallons of gas worth in energy in the battery). I know this is part of your point (make gas engines more efficient), but it feels like an important omission in your comparisons

[@djneils100]

guessing but I imagine that an ICE loses a lot of the potential energy from it's fuel to heat and noise. I would imagine electric cars are much more efficient at using the energy in their batteries

[@AJLethal]

I suppose he ommited that because the crux of the issue with batteries is that they weight and take more space than a gas tank.

[@b22chris]

Trevor K he was discussing energy density. Gas engines are only like 33% efficient. Battery powered cars are far more efficient which is why the can go so far with less power. Gas engines lose efficiency in heat and friction.

[@rapnjoe]

You left out the most important category in your comparison, "Efficiency" Ice is 20 to 35 %, EV's at 59 to 62 % when you showed the equivalent Tesla battery pack with 3 gallons of gasoline you need to point out the Tesla battery pack goes 300 miles of range, how far will 3 gallons of gas get you when the average MPG is 24.9 MPG even if you took your most efficient gas cars 58 mpg the 3 gallons takes you about 150 miles in range,the Tesla takes you double that. the average 24.9 will go 75 miles of range , Efficiency always wins long term and your going to have to make a new video after April when we learn more from Battery investor day.

[@shawnmetzger4518]

Then IC will just keep getting better and better because of all the room for improvement. EVs will plateau very soon.

[@TheNasaDude]

Electric motors did already plateau because they are older than ICEs and extensively used in manufacturing plants and a myriad of applications. They are also simpler, so less components to improve, and they were more efficient to begin with. Of course battery technology is far from perfected, and a lot is being spent in energy production technology. Another field where I expect improvement in the long run is distribution efficiency, because of continuing research on superconductors and metal alloys pushed by other industries

[@luislugo4411]

I wonder how paid him for this explanation. Maybe exxonmobil or beyonpetrolium

[@DOZDDMGator]

Thats true but thats also a case for why ice have room to improve. I think at best ice only utilise 20%(i cant remember the actual figure but its low) of the energy from combustion. Theyll never get 100% efficency but they get it pretty high eventually

[@martian9999]

@@DOZDDMGator no they won't. Folks have been working on improving the efficiency of ICEs for decades. The low-hanging fruit has been picked. Anything new involves complicated and unreliable technology. The consensus is that the efficiency of electric motors will never be reached by ICEs -- especially since the latter are getting less and less R&D investment.

[@johnmiller732]

[@jackkrueger4150]

I'm honestly quite curious why hybrid cars aren't an obvious interim solution. Don't they share some of the benefits of both electric and gasoline cars? You have the preexisting (and cheaper?) infrastructure and energy density of gasoline engines, with the reduced emissions of electric sans the insane batteries. Think about when you are stuck in traffic; instead of having to burn gas constantly to idle and move slowly, you just use electric, right? I'd be interested to see why the decision HAS to be either gas OR electric, and not a combination. Could you do a video on that?

[@johnjamesbaldridge867]

Terrific point. I have a 2017 Kia Niro and drive it as slow as possible to and from work because I listen to audiobooks. I can drive almost 700 miles on 11 gallons of gas. It's going to cost me way less over the lifetime of this vehicle than an electric car. On the highway, cross country, I get 45-50 miles per gallon at or under 65 MPH. It goes down to low 40's if I go faster. But that means I can drive up to 500 miles on a tank that takes me, what, five minutes? to fill up. And I _like_ getting stuck in traffic. I can get 80 MPG! EDIT: The main problem I have going cross country is having to pee between fill-ups ;-)

Hybrids are actually considered worst of both worlds Batteries of hybrid system adds weight to the car so the engine has to work more . So they end up giving similar mpg. Now this is in present cars. I don't know if its technology can be advanced to be better. But, atleast for now , thats the fact

[@johnjamesbaldridge867]

@@nagendrakudchadkar3649 All I can say is my car _averages_ 50 MPG _at its worst_ and over 60 as long as I stay off the highway. Going home from the office is slightly downhill and I can get 80 MPG on that trip, and 60 going the other way. This is significantly more than a car of similar size which can do at best between 35 and 40. There are other advantages as well. The car does not use a lead-acid battery so that never has to be replaced -- a Godsend in Arizona where even the best batteries can't last more than three years. The other thing is that the engine in fact works _less_ -- that's because it's an Atkinson Cycle engine sacrificing horsepower for lighter weight and and better heat efficiency. It means I can use the cheapest gas possible and it means I only have to change my oil every 6-8000 miles, using the cheapest oil. Those are the facts as I have experienced them.

@@nagendrakudchadkar3649 Plug-in hybrids are the best of both worlds. I drive about 90% of the time in electric mode and only bought 20 gallons of gas last year, yet I have no range anxiety. Even though the battery is only one-fifth the size of a full electric, in 4 years it has lost less than 2% battery capacity.

Gas is dirty but power plants are too & solar/wind based power is unreliable & probably shouldn't be rolling out in major use now either.
