How Fast Can I Charge The GMC HUMMER EV In Just 15 Minutes? The Answer Is Surprising!

@@alanj7306 The fixation on DC fast charging is kind of absurd since almost all charging is done from level 2 AC, in a parking spot, during downtime. Sure, grabbing diesel is a 10 minute stop, but that's going to be a ten minute stop every single time you need fuel, whereas an electric truck takes all of 5 seconds to connect in your driveway or garage once a week, then left to charge overnight while its not in use anyways. As an aside, I think we'd be better off taking a look at a lighter and more efficient trucks like the upcoming F150 lightning or Silverado EV to actually gauge what DC fast charging is like for a more practical truck - the old Hummer H3 truck isn't exactly a marvel of efficient truck design and got about 340 miles on a 23 gallon tank - pretty crappy for a truck.

The Model 3 LR can charge at over 100kW all the way up to 70%. With a 3x larger battery pack, the Hummer EV should be able to do 300kW+ all the way up to 70%, but instead it's struggling to break 200kW at 50%. It's not clear if the bottleneck is the vehicle or the charger, but either way this will be the consumer's experience. I don't expect them to match Tesla, but this doesn't even look close. I guess we'll find out more if they do a more thorough test starting with a lower SOC and different chargers, but it's not looking great in this limited test.

And in the case of the HUMMER EV, do you really think that stopping for 30 minutes for every 7 hours of driving is a huge sacrifice?

So, for putting things in perspective, he added 45.95 kW into the battery in 18 minutes, which means it charged in average at a speed of 153 kW starting from 53% SOC to 75% SOC. This charging speed is way above what a Tesla can do at the same SOC. Tesla is around 80 kW average charging speed from 53% to 75%. So the Hammer charges two times faster than the Tesla M3. If the Hammer was a lower SOC (state of charge), I am sure the average speed would have been above 200 kW, which in 18 mins would add 60 kWh in the battery. For a total of 18$ for about 100 miles. A truck of same size as the Hammer would be rated at 15-20 mpg. That's 5 x 5.084 $ (Diesel) = 25 $.

Chargers are often 1000volt at 350 amp aka theoretically 350 kW. But since it is 0nly pulling 800 volts and even that gets throttled down to 80% you would see around 225 to 280 kW top speed. Also top speed is seen around 10% and then drops 55% battery capacity at 178 kW is very good. I just spent 1 hour 15 minutes adding 25 kW to my Chevy Bolt EV.

[@underwaterdroneservices7292]

Will the grid handle ALL cars being EV? Elon Musk has said that the entire US electrical power requirement could be supplied by one 300x300 mile area of solar panels. I thought "whaaat, no way" so I did the math and it is very conservatively true. Home charging currently is about one third of the charge cost in this video. I believe that it is not emphasized enough that home charging will be the vast majority of all electrical vehicle charging, not roadside charging (I also believe that the convenience of home charging will easily counterbalance the inconvenience of much less frequent roadside charging (not for trucking though, hmm)). Lucky enough, home charging almost always takes place overnight when the grid is not highly used. I haven't but someone should do the math of how much electrical power it would take for all electrical power consumption, including the charging of ALL vehicles being electric, overnight versus the typical overall daytime consumption. The rough math is not actually too hard to do. The current grid at current max use likely has a relatively small buffer to overload. If the calculated overnight factor (including all EVs charging) exceeds the current daytime max then the grid has to be upgraded. I haven't done the math, the factor could be even or it could be 5 or 20 times. If the grid has to be upgraded then you can bet the cost of at home charging will rapidly be increased to likely even more than the current fuel costs. I highly suspect that reduced cost to the consumer will NOT ultimately be a benefit for EV conversion but more likely will be justification by the powers that be to increase the "fuel" cost of vehicle travel! Someone has to do that math.

[@andrewt9204]

The one figure I saw was around ~30% adoption rate before electrical grids will need significant upsizing. I think that 30% will take a while even as popular as EV's are right now. What is it now like 1-2% only in the US? The same argument was made back when central AC was getting popular. All these homes built in the 50s-70s with only 60A electrical service couldn't handle central AC without compromise. Everything back to the utility needed to be slowly upgraded as AC got more and more popular. Same will need to happen with EVs. I've noticed that when new major powerlines are being built, they are usually only 1/2 or 1/3 populated. I assume that's on purpose so if demand keeps increasing they can just add more transmission wires. And maybe a good solution is for utility companies to offer significant discounts on rates and charging equipment if you only install 30A of charging or less. Which should be fine for most, and would probably stretch out the time needed to upgrade utilities by a large margin. Maybe that could support 50% EV adoption if the majority only had 30A charge circuits. 24A is all I charge my Model 3 at, and my daily commute is 120mi. That recharges in 6-7hrs overnight depending on how cold it is. However, if vehicles like this Hummer or other full size electric trucks with 150kWh+ packs get popular and households get more than one large EV, a single 30A circuit isn't going to be enough. But a household with 2 standard sized cars could, especially if both vehicles only travel ~50mi a day.

[@underwaterdroneservices7292]

@@andrewt9204 I took a closer look at reports and there is a full range of expectations. Most are positive and say only typical upgrades necessary but others say otherwise. I don't think I heard of the possibility of rolling blackouts in North America, due to electrical supply, until the last couple of years (without EVs). The grid has to support the absolute worst case at all times, especially if transportation is included. If there is already problems occurring then all vehicles as EVs seems like it will make matters much worse. Some say EVs will improve the grid by acting as available stored power for those problem points but I really don't think people will take too kindly to only a 75% charge in their cars because it's a hot day when they expect 100% (when they need the charge most themselves).
