This is such an excellent point that as a ‘conventional’ car driver has never crossed my mind, we are always too concerned about how long the charge will be yet it’s completely irrelevant. Most electric cars have a minimum of 100 mile range, when do you regularly drive more than that in one trip? My commute is a 45 min drive which I would consider fairly long yet it’s still only 21 miles each way. So even a 50 mile range would cover my commute until I’m back home to charge again! No need to charge mid way! Thank you!

[@rogereverett9095]

Untrue!!!! How many mk1 and mk2 leafs were produced , most 'new' electric cars !!

[@stuntmanwill]

@@rogereverett9095 what’s untrue?

[@rogereverett9095]

You said most ev's have at least 100 mile range., I guess what you meant were most new cars. Out of the 400k registered evs on uk roads there's more 200k of older pure ev's on the road with less than 100 miles range. Ie leafs , Zoe's, mini's ,smarts, etc. Very few of those generation of cars have actually been scrapped.

[@stuntmanwill]

@@rogereverett9095 i thought all those you just mentioned do have at least a hundred mile range?

[@rogereverett9095]

Unfortunately not , 24kw leaf 85miles, 30kw 105miles , Zoe 22kw , about 90miles , when new, but...... after degradation and 97k miles my 24kw leaf will do 72miles. A friend has the 30kw and only get 74miles(apparently batteries are not so good). We love our leaf had it 4 years, paid 7k and we have borrowed the new leaf demonstrator from nissan dealer, but honestly for 30k it's pretty much the same car apart from range of 147miles. Infact lower spec'd So I'm looking into upgrading the battery to 40kw or an extender pack, but unfortunately the company doing the conversions in uk have been having issues with the kits

[@LosZonga]

I just love this is simple clarification, had a debate on other EV channel about this set of mind: you start with a full charged car so most of daily driving or even a big part of the driving is done with a charged car and you always can find a plug at the destination while not most of friends have a petrol station at home ;) Thank you for making that clear.

[@timothyratcliffe4471]

Hi Richard. Love your tech series. Just a little pointer on this subject relating to "Granny" charging. We have done this when away just out of interest with our Leaf and been very surprised, using the logic as you say of when you stop you plug in, we were easily able to cover our charging needs while on a stay in the new forest. In fact having travelled 200 miles to the destination and driven around various engagements whilst there, we had 95% charge ready for the home trip. So while granny's slow she should'nt be dismissed!

[@ElectricClassicCars]

Sorry if I seemed to dismiss them, that wasn't my intention. I've often used them at destinations, like the mother in law's, who don't have a 7kw wallpod. They can be very useful. 👍

[@shantipless5846]

Yes- I commuted to work for years with just the level 1 wall outlet charger- got about 50 miles a night.

[@jeffreyquinn3820]

At any place in Canada or the northern US, a lot of workplaces & the majority of apartment/condos already have plug-ins for the block heater that will handle the granny cables. You'll find the odd parkade & hotel parking lot that do as well, but I expect EV charging is something hotels will start offering soon, if they don't already. The largest gas station owner in Canada is already converting gas stations in British Columbia to "premium fueling/charging destinations" with coffee shops, restaurants, kids play areas & short walking paths, & will start in Ontario in a year or two. I think the idea is to stop every hour or two to recharge your car & yourself for ten or 15 minutes, but they're foreseeing a lot of profit changing from selling gas to selling electricity.

[@jw1oon]

Thanks for covering both the US & UK/Euro standards. This is quickly becoming one of my favorite channels!

[@glenhardy4770]

Thank You for explaining what you have! I live in California and hope to convert my 1961 Chevrolet Apache to electric one day.

[@rossgebert9422]

Fantastic episode. Love these TECH TALK's. Can't wait for a series of Build videos.

[@aaaa-ig6sc]

@15:20 Worth mentioning with three-phase, public charging is at 400V, and it's square root of three because of the Wye connection. 32A * 230V * 0.001 = 7.4kW 32A * 400V * √3 * 0.001 = 22kW 400 / √3 = 230 Whilst 230V is the on paper target (+/- 10%), most of UK homes are around 240V and some up to 253V (230*1.1) The cars onboard inverter is still the limitation so the extra kW isn't useful. Modern EVs opting for a 7.4 (single-phase) 11kW (three-phase) AC max and use CCS for rapid. The 11kW comes from 16A even with 32A 16A * 400V * √3 * 0.001 = 11kW Rather than the 22kW and 43kW onboard that older cars like the Zoe had.

[@d.beaumont9157]

Brilliant presentation Richard, nothing would make me happier than to plug my vw crafter in when I get home and never stop at a petrol station again.

[@humphreybradley3060]

Great video Moggy. The estimate is for the average EV owner charging 60% at home, 20% at work, 20% on the road

[@ElectricClassicCars]

I've read a few articles in the past and they're always around +90% for home charging, around 7% charging at destination and around 3% on route. co-charger.com/knowledge-base/a-simple-guide-to-charging-an-ev/

[@Yaaayishere]

Excellent teck talk. I like to refer to chargers in miles per hour as it relates more to daily use. So the granny charger is about 6 miles per hour, the 7kw home charger is 24 or so and the DC chargers are 150-1000 miles per hour.

[@deltajohnny]

Very useful data! 👏👏👏

[@twillems2285]

I understand your preference but not all electric vehicles have the same efficiently. Other conditions such as weather, temperature and driving style have significant impact on efficiency and thus range. to put this into perspective. a V12 Ferrari and a inline 4 Volkswagen have completely different fuel consumption. if we compare fuel pumps using km/s your results will depend on the fuel consumption of the vehicle.

[@jeffreyquinn3820]

I believe the new Hummers & maybe Esplanades have battery packs that split into two for rapid charging and can be plugged into two rapid DC chargers at once, or one charger with two outputs or something.

[@cmoor7928]

Great lesson for all of us Richard, thank you. By the way, keep bringing you're amazing and innovative creations on to Carwow, and showing the broader audience just how much better, efficient, and simple the electric world is. Cheers

[@ElectricClassicCars]

@@stephen_101 Thanks. I probably would have won all the drag races if the battery wasn't sub-zero. It got faster as I did more runs, as the battery had time to warm up. But I think 0-60 in 3.8 seconds is fast enough in a Land Rover. :-)

[@ian-lg6vu]

Hi I have an Mg5 long range I charge at work once a week from around 40% to 80% on a granny charger and once a month I do a balance charge up to 100% on the granny charger at work So as you say the car is working for you while it’s parked up I have only rapid charged 3 times and that is when I’m on holiday from work Really enjoying these tech talks and vintage voltage on the tv Cheers Ian 😃👍🏻👍🏻👍🏻

[@CrownRider]

Excellent video, thanks. Normally I charge the battery when it is at 30-35% up to 80-85%, overnight. Only when I have a long trip the next day, I charge it up to 100%.

[@ElectricClassicCars]

Perfect. 👍👍👍

[@R08Tam]

I do a lot of camping. Two of my favourite sites are quite happy to let me plug the granny charger in on the pitch. It's great waking up every morning to a fully charged car ready to go exploring. I think that sites are more and more going to find that this is a selling point.

[@ElectricClassicCars]

I agree. I've been doing that for years at campsites in my VW Bus. 👍

[@Lesjaye]

I have a 2017 30kw/hr Nissan leaf with 3.3kw max charger. I use portable (granny charger) for 99% of my charging needs. It is plugged into cooker outlet with 30 amp wiring. It doesn’t get hot or even warm at all. There is a temp sensor in plug which reduces charge in such event. My car is parked 25 metres away from my consumer unit! I was quoted £1500 which included grant for 7kw smart charger. That’s £1500 for an extra 1.1kw charge speed! True!…..it doesn’t have pen fault detection. Leaf has a charging timer for smart tariffs.

The way you cover off how EV’s are used and charged is something that’s missing from my studies. It’s at least as important if not more so than the technical information covered off in my studies. Thanks heaps!

[@stophdoggy6625]

An episode on optimal battery placement when doing a conversion would be interesting. Many conversations have batteries in boot spaces, or too much battery weight over the front wheels (in place of the engine). The low mounted under floor placement of the batteries is optimal but is it possible with a classic conversion? Has anyone out there attempted this? Super Fast Matt’s ol’ Jag is one that I’m aware of but the modern car is quite a different challenge.

[@evs2k]

We don't often have a lot of choice. Superfast Matt has the ability to install Model 3 batteries because of his huge Jag. The rest of us are just cramming them in where ever they fit.

[@scottcarr3264]

Yes, "SuperfastMatt" has done a Vintage Jaguar with tesla battery under the floor.

[@RedBatteryHead]

Great vid. Great to see the inboard charges are that small already.

[@ginggur17]

I’ve never known much about the charging side, brilliant Richard Thankyou.

[@karlgt9989]

Love these tech talks, you make things sound so simple. I would love it if you could cover how you would go about deciding what the optimal system is to install in the classic you are converting. So, how do you calculate the motor size, the battery pack etc is it just based on power the client wants or the range, or both?

[@davidearle2514]

Although I'm an avid follower of your content and your videos are brilliant. Not everyone has the facility to charge from home (e.g. living in a flat or have to park off road).

[@ElectricClassicCars]

That's totally correct. Only 75% of car owners in the UK have access to off street parking the other 25% have to charge at publicly available chargers. My father lives in a flat and chargers up at Tesco when he shops, at public car parks and at other free chargers. We call him the Plug Pirate, because if there's a free charger, he's there. I can't remember many free petrol stations back in the day. 😆😁👍

[@hevendranarayansamy2793]

Hey Moggy. I'd love to know how the ac and heating systems works. Please do a video. Does the batteries require their own heating and cooling separate from the occupants of the car?

[@scottcarr3264]

Short answer, ...Yes.

[@sydneyg007]

I really like your explainations on why charge speed is not as important as most people that haven't had an EV think it will be. My only bugbear is referring to an EVSE (charger interface cable) as a "Charger" and the fact that there is no such thing as a "Home Charger". There are higher rated EVSE's/granny cables that can do 7kw no problem. The bigger wall mounted box's are just more expensive non portable EVSE's. We have a 32amp power point with an up to 7kw adjustable portable EVSE. To be honest we very rarley use it at 7kw and 90% of the time have it turned all the way down to 8AMPs (1.8kw). The bonus is that they are way cheaper than a non portable version and we can take it with us!

[@KiwiNeale]

When I tell people about charging an EV on longer journeys (we have a Tesla Model 3) I say the method is to do "top ups". Travel a couple of hours and have stretch, loo break, or a coffee, and do a charging top up at the same time. Apart from long journeys, we never have to stop for a charge.

[@ElectricClassicCars]

Same here. 👍

[@nickcooper14]

Great explanation. I’m learning more and more with each video👍🏼👍🏼🇦🇺

[@Hyfly13]

People underrate the granny charger. With no off street parking we've been using that as our primary device for two successive cars over six years. Typically it charges around 7 mph (adds 7 miles range per hour of charging) which means two or three times a week we plug it in overnight and 10 hours will add 70 miles. You need to know how to look after your cables (cable protector over the pavement, rain proof 13a extensions) and understand how not to overload your ring main or overheat (always fully uncoil extension leads). Of course it's slow but as Richard says, you wake up and leave the house with a full (enough) battery for the day. Occasionally we'll use a public charger, or a free destination ( eg supermarket) Fast Charger and they are quicker, or for the 6 days a year we do a long haul we can Rapid charge (even faster) on the motorway while we stop to pee. I don't spend any time charging - the car does it ;)

[@ElectricClassicCars]

Free chargers are great. Never seen a free petrol station though. 😆👍

[@dixonsindorset]

Hi Richard. Loving the tech talks, thanks. An idea for a future episode is to show us what goes on at the other end of the CCS cable, inside the car. There must be a normal(ish) AC charger for a type 2 connection, but what kind of electronics handle the DC? Or is it an expensive combined unit?

[@andrewtaylor641]

Thank you, loving this in depth dive tech talks. 400v vs 800v be interesting plus grounding as I near some cars can be picky about the chargers they use (eg. Zoe). Why can some cars charge at 50kw and others at 300kw? Keep up the good work, really enjoying these.

[@deltajohnny]

Very interesting information! 👏👏

[@Senna007uk]

Another great informative and interesting video, these more tech focused videos are excellent yet still get the information across without getting too complicated for those new to the technology. I have a quite specific question - Does the charger have to be permanently connected to the battery system onboard the vehicle? or could you have it offboard and connect it just for charging? The reason i ask is im making an EV kart and keeping weight down on the actual kart is critical to performance so having the charger offboard would make a big difference.

[@ElectricClassicCars]

Great question. On the race car I'm building I'm having my charger off vehicle to save weight. 👍

[@itchywitchy]

You are right about charging, it's definitely a mindset shift and the analogy I use when talking to people is that you leave home with a full 'tank' of electrons. I very rarely use public chargers and I suspect that's true for most EV owners who can charge at home.

[@murrieteacher]

good video mate.

[@johnshuker8892]

Great video I like the tech talk. Is there there a limit on how quickly you can get the energy back into the batteries themselves, you talked about the rapid charging, can the batteries or type limit how fast they can be charged . I'm thinking cooling as 1 issue. Also will it affect there life? John

[@Jcewazhere]

I like to say a basic wall outlet, here in the states that's 120v @8 amps, will get you 3 miles per hour into your battery. A dryer or other large appliance outlet, or an installed charger, will get you around 30mph. And a DC fast charger will get up to 300mph into your battery. There's a lot of simplification in that, but it's easy to say and clear enough. I've owned my Bolt for about a year and a half, still don't have a fast charger installed at home. Do almost all of my charging on a 'granny cable'. Only need public charging on road trips. 3mph overnight, plus sometimes more at the destination, is plenty for 90% of the trips I make.

[@tomorrow-man]

Fantastic explanations - I've been driving EV's for nearly 3 years and I'm learning from these

[@stefansmith7054]

The best explanation I've ever heard! Thank you. I've never thought of it that way about chargingspeed but as you said most people out there are comparing chargingspeed with the time it takes to fill the tank with 70 liters of fossil fuel.

[@michaelbedard7859]

[@dazgreen]

You can’t say that people need to stop worrying about how long they take to charge. If someone’s driving 250 miles a day they need to know how long they’re going to be stuck at the service station for on the way home. It’s a very important factor if you’re not going to be charging overnight

[@Vintage_Volts]

Thanks so much for another tech talk! Love these, they are very good at braking it down to basics, we all need refreshers on those. What i would find really interesting if you could go into, is 1. How do you make battery boxes……more importantly what do you put in them and what do you put outside of them, ei contractors, fuses etc. Also 2, but still goes with the battery box questions, is how do you run the cables through the car, so what type of grommets do you use in and out of the battery boxes, and generally in the car? When do you use bus bars and when just cables…….. So i would love to Hear you do a deep dive on these questions:-). Thank you

[@sandywebster1529]

As far as I gather, provision of rural charging points is still rather sparce, and I have friends who have encountered charging points out of order. Also in rural areas single points can often be occupied. Even at filling stations you can ending up queing at times. So overall theprovision of charging points remaind a problem in many areas.

Very good content. One question. I have an electric motorcycle that is 87.6v 160Ah for a total of 14kwh LFP and I really want to be able to charge in a station unfortunately I know DCFC is out of the question but being able to charge in a AC ~20kw station would be a total win. How I could achieve it?

[@mavenmavenpest1750]

Very informative thanks. Question- is there any benefit to letting the battery run down and then recharging to full (or near full) ? Would that preserve the battery life ? Also do you think there will ever be a model where the battery pack is so small that you will pull in, unload your used battery and plug a fresh one in? Like a closed loop of batteries just being swapped around between vehicles.

[@MrHemlock51]

There’s a couple of Chinese car companies working on battery swap technology and have stations that can automatically change a battery pack in a couple of minutes. Being an authoritarian country helps because the government can tell different companies to cooperate in designing a universal battery standard. That would never work under our capitalist system.

[@poxcr]

Even the slow 'granny chargers' can be sufficient if your daily mileage is not too high, which is usually the case for city cars.

[@locknut5382]

Thanks Richard. 🙂👍 So, am I right in thinking that, with a simple peak power management system, you can trickle-charge with DC directly from a solar PV system if the panel voltage is high enough? That would eliminate DC - AC and then AC - DC conversion losses.

[@Ratty_Rex]

Great explanation and history of the charging. Am I right in thinking that you can use a type 2 charger on the CCS too?..... it just won't charge at the DC higher rate..... just "normal" type 2 (or phase 3) All we need now is for petrol stations to have as many charging points as petrol pumps..... and all car parks to have 50% (eventually 100%) of the spaces to have charging points too. 👍😉

[@ElectricClassicCars]

Yes, you can charge using the Type 2 charger on a CCS. 👍

[@MrKjetil101]

Your petrol pump charger is awesome😍 I want one so bad😩

[@123rkss]

granny cable is more than enough for most people. unless you drive more than 150 km per day. overnight charging via granny cable covers that up nicely. say you come home at 8 pm and have to leave at 7 am. thats 11 hours of 2.5 kW, will give you 27.5 kWh > more than enough to cover 150 km however, you have to make sure that your wall outlet can support that load for extended periods of time

[@rikardottosson1272]

What are the smallest conversions where you fit CCS? To me - I don’t mind non-Tesla like range in let’s say some converted sports car, because fewer batteries => less weight, but then it would still be really nice with some rapid charge capability for the occasional road trip.

[@JamieLovick]

Just out of curiosity, what brand chargers are you using these days? Are the CAN messages typically programmable? I'm looking for an option to upgrade my OBC/DCDC on a Mitsubishi i-MiEV and change it from a J1772 to a to 3 phase Type 2.

[@winkcla]

You didn't cover which DCFC controllers are available for conversions! I know about the kit from Zero EV, are there other options? I've heard people re-use OEM hardware with reverse-engineered protocols as well. All options still seem very costly for something that "just" needs to talk from the BMS to the DC charger. Other fast charging question just out of curiosity: are you able to get AutoCharge to work on your conversions? (like Fastned/EnBW). As I understand it uses some sort of unique identifier that is part of the CCS protocol, I wonder how this value is set when using a CCS kit, and whether it will be whitelisted in Fastned and other's databases.

[@mikeselectricstuff]

Damien Maguire has got the BMW i3 CCS module working on his BMW conversion ( details at the openinverter forums, fast charging section). Autocharge uses the MAC address of the CCS controller ( similar to ethernet addresses), which is factory programmed into the GreenPhy comms chip firmware in the CCS controller AIUI for autocharge, cars are enrolled via a charger, which records the address and associates it with your account.

[@commonsense2938]

Is it good like solar dc chargeing set up with out converting to ac

[@niklaswo]

Question: so the typical wall charger you get at home what does that do if, as you say, the ac to dc converter is in the car? Is the wall charger then only about enabling higher amps all the way from the fuse box up to the car? I have a Honda e with their wall box plus a ‘69 Alfa I probably will convert sometime in the future. Thanks for awesome content!

The wall charger usually gets its feed directly from the homes incoming supply, so that it can provide the 32amps max that a 7kW charger can go up to.

@@ElectricClassicCars i.e. no converter in the wall charger? I also have 3-phase wired to my wall charger but I believe the Honda e doesn’t support it 😅 But for future cars…

Never heard of granny charging. Funny thing is I use that to charge my plugin hybrid.

[@philtucker1224]

Can all the new cars coming on to the U.K. market get charged up via any or all of these and how will we know which one to use?

[@jordanjones9210]

On EV conversions with DC fast charging, how do you communicate the vehicle’s charging needs to the charger? Is there a standard protocol, and are there off-the-shelf solutions for home built stuff?

[@trevorsmith1859]

Question about fast dc charging, I live in a terrace house so can't charge at home, the only on street chargers in my town are several miles from my house so not ideal but there is a fast charger in the supermarket, now does using fast chargers all the time have a detrimental effect to battery life. Enjoying the videos ant tv series.

Yes, constantly hammering the battery with DC rapid charging will shorten the life of a battery compared to one that primarily used slow charging over its life time. But the impact isn't as big as people make out. 👍

Very informative, thanks for sharing. I've recently retired and try to split my time between Thailand and Denmark, if I were to buy an EV and leave it plugged in at my house in Denmark for up to 6 months at the time, would that be an issue if left unattended? Will the built in charging wizardry handle vampire drain, will I damage the battery or set the house on fire in my absence? Please add that to your Q&A session if you could, I know I'm not alone with this concern, thanks.

I had similar thoughts. In addition what is the best way to take care of a modern say... Tesla type battery. In the old days of batteries we were told to discharge them totally and slowly charge them to full to maintain a better battery of its life. Does half charging, swapping speed of charger and topping up here and there, affect a modern battery or is no longer a concern?

Hi just started watching your channel as slowly getting onto ev cars (outlander PHEV) as wasn’t sure about being able to charge up as live in terraced house. Have found it really good and should have gone full ev I think but will have to wait. Quick question as my car has type one plug-in I’ve seen type 1 to type 2 cables are these okay to use? Sometimes when finding a charger they have been ones you need your own cable which would be type 2 so I couldn’t charge there so seems like a good plan if can use the cable.

[@ElectricClassicCars]

Yes, I've used Type 1 to Type 2 cables in the past, they work fine. 👍

@@ElectricClassicCars thank you for that. I will get one very soon then. 😎
