For those who are curious. Still plenty of details missing here but these numbers are an impressive start.

• 800-volt DC public fast charging compatibility of up to 350 kilowatts. Industry-first technology mechanically switches the batteries from parallel to series mode during charging, which makes HUMMER EV compatible with the fastest 350 kW DC fast chargers, enabling nearly 100 miles of range in 10 minutes of charging.

I saw lots of comments from last night from Tesla fans that there's no charging infrastructure like Tesla's supercharger network. It's like people don't know there are literally tens of thousands of other charging stations across America.

With tens of thousands of more coming. GM has partnered with various companies to do so. By the time the Edition One's and EV3X's start hitting the roads, the charging network will be nearly (if not greater than) double what it is today. 100 miles in 10 minutes is the best in the biz!

What do you guys think is a realistic charge time on a standard Level 2 charger that can be installed at home? I've read under 30 hours, which I hope is a broad range. A full 30 hours isn't ideal, but something like 10-15 would be much better.

So from what I've heard, on a standard Level 2 home charger, you can expect to get anywhere from 17-20 miles of charge per hour...that drops to 2-3 for a Level 1 lol, ouch. Let's say 18 for the Level 2, you plug it in for 12 hours overnight, and you've got 216 miles of charge added by the time you leave for work the next day.

Here's a screenshot fro the reveal video that gave me that 18 miles/hr charge rate. Since the 350 kWh fast charger will give you 100 miles in 10 minutes, this has to be the Level 2 number.

This will depend mostly on your house. The Hummer will be able to charge Level 2 at 19kW, however most people will have to upgrade their home electrical infrastructure to provide that level of home charging. I guess the thing you have to decide is how often you plan to charge, and what your typical battery buffers will be. I typically drive 50-100 miles a day, which would be 25-50 kWh of energy out of the Hummer EV, On a standard 50A 240V circuit you can pull 10kW safely, so I would need to charge 2-4 hours a day, or more if I charge every 2 days, or all night if I went every 3 days. I have had EV's for 8 years, so I am comfortable pushing the limits. I like to put the battery through less cycles, and try to avoid High Speed DC charging altogether whenever possible. When my Hummer arrives I will likely charge it a couple times a week overnight. But will be excited to hit my local Electrify America 350kW charger at least once, if for nothing else to see how warm the cord gets charging at that high rate. My E-Tron only draws 150kW, and you can definitely feel it in the cord.

Well, the Tesla Supercharger network is great, however, depending on where you live, and travel to there are many other great options. The largest upcoming network is Electrify America, which is VW owned. Electrify America: U.S. EV public charging network | Electrify America I also recommend using the plugshare app, and setting the filters for CCS Combo . I live on the west coast, we have great coverage using only Electrify America network. I will attach a map dark dots are active stations, and light grey dots are in development. I heard Biden say in the debate last night that he plans 50K more Freeway EV charging stations.

Thanks guys. Both of what you said is helpful. I drive about 50 miles per day, so if it's 18 miles/hr and I have to charge it for 2-4 hours every night, that's no problem. I also have access to a charging station at work, so that won't be an issue. As long as I'm not feeling like I have to immediately plug it in when I get home and keep it charging all night just to stay afloat, I should be good to go!
