You guys had me crunching numbers on this one.

Check my math tell me if I’m missing something: 212 miles of range at an estimated $60. Gas around here is +/- 3 dollars per gallon. That same $60 would purchase 20 gallons of gas. Dividing 212 miles by 20 gallons gives an equivalent of 10.6 miles per gallon. Seems like a hummer to me.

At first I was considering one of these, but this just sounds totally impractical. You have to locate one of these stations that's convenient for you, then you have to kill probably close to 2 hours had they been near empty and filled up completely, then you're still paying probably 100 bucks. On top of that, once they get the population on EVs, they'll crank up the charging cost to equal what you would have paid in gas anyway. This would probably take several days to charge at home. I think im going to pass

It would take exactly 24 hours to charge on the home charger I have for my two plug ins. 19 hours if I upgraded it to 50 amps. But that's from 0-100%. And you'll almost never be in that situation. The worst case scenario would be if you're coming back from a road trip and you return with nothing left. But even then you only need enough to get you though the next day, which for most people is going to be less than 100 miles.

Roman & Tommy, Next time I wonder what would happen if you grabbed the charger next to it and plugged it in once the original charger slowed down. This would show if it’s the charger itself that’s heating up and slowing things down or the battery on the vehicle slowing things down. This might be a way to get charged faster by switching chargers every 15-20 mins. While this is better still waiting an hour to get 212 miles miles of range doesn’t compare to a 5 min fill up which adds 500 miles of range on an IC truck.

If the slowdown in charge rate is due to heat, then this is kind of like laptop computers which have an amazingly fast CPU/GPU but then throttle back the speed right away because their thermal design cannot dissipate the heat fast enough. It would be better to have a somewhat slower max charge rate which could be extended for a much longer period of time.

[@foellerd]

With small electric RC vehicles the charging rule of thumb is to charge at a rate that matches the MilliAmpHour MAH capacity of the battery. So a larger battery can charge faster basically. For example, a 700 MAH battery should charge at .7 amp and a 7000MAH battery should charge at 7amps. With the Hummer EV having the biggest battery on the market I’m not surprised it also charges the fastest with that in mind.

[@supergeek02468]

Yep, that’s the C rating, or capacity per hour. Even at 300kw they’re only charging at 1.4 C. Model 3 maxes out around 2.5 C when it’s under 15%

[@jghall00]

You also have to consider paying k voltage and cooling. When I did RC, my version of cooling was a fan. These vehicles are more sophisticated. And higher voltage means faster charging without increasing current, which builds heat.

Nope, the limiting factor is virtually never the charger. Its the battery. Its inevitable, charging at over 100kw will superheat any battery. Its much more efficient to charge at 200kw or so and not have to wait for the battery to cool itself. The charging curve on this vehicle is, quite frankly, very poor. In fact the bigger the battery is the more you want to avoid super high charging rates since the larger the mass the higher the more you strain the cooling system due to is greater specific heat mass... Its like a digital camera packing it with more pixels does not translate to a better camera, its just another spec among many.

This is called parallel charging and it looks like some manufactures are considering this but your limitation is still the plug your changing and the station you pull energy from . And on top of this bms systems in the distraction of energy per cell already divide the energy . Limitation is really how fast you can safety charge each individual cell. If the cell can be charged in 10 mins then in theory the entire pack could be theoretically charged in 10 minutes regardless of size but it’s once again the distraction , heat management, Volts , Amps and charging losses . A pack of 200kwh size to charge in 10 mins should probably take some kind of insane cooling system of cables , the pack , the charger and extreme voltages of 4000 volts at 2000 amps

GM has applied a patent for this

Charging speed testing/rating should be benchmarked on TIME to MILES ADDED. Using "20% to 80%" handicaps vehicles with extended range (Like a Lucid with 500 miles of range) and benefits cars with small batteries and miniscule range. Using "kWhs added" will benefit vehicles with inefficient motors/mass like that Hummer, iPace, and Etron. They may be able to add 50 kWhs of energy at a fast pace, but that doesn't mean you'll be able to make it to the charger 150 miles down the road. The only* situation where charging speed is important is the intermediate stops when travelling long distances. If you're trying to minimize the time you spend charging on a road trip, getting another 200* miles into your battery is all that matters. (* I think 200 miles is a good range to compare against, but I'll admit that for cars with

Any auxiliary AC power outlet? What maximum power output?

I just seen a trailer with 3 Hummer EV's on a trailer on I-75 south!

If you guys had the truck on, it will slow it down when the AC in the cabin tries to cycle at the same time as the battery cooling.

Try plugging it into a 120 volt outlet. Oh that only takes 4 days to charge. Got it.
