That particular Hummer only had a 165kWh battery (300 mile range version). It is 60% to add 100kWh. I suspect it may have also been charging at 400V, since it was one of the early prototypes, not one of the preproduction Hummers.And it's a big ass battery that has an 800v architecture. That's part of the reason I've been so pointed about being borderline disappointed by the rumored R1T curve. The R1T only pulling 145kw at like 50% charge is very conservative, and I hope is a software decision by them to learn more after production than a hardware limitation.
That's pretty nuts. A couple of notes:
1. Don't trust the "vehicle requested" value blindly. I've seen it wrong several times. I'm sure they'll fix it (and maybe they have), but it hasn't been reliable so far.
2. How is it at 140kW, when it's taken 45 minutes to charge 99kwh. The rate increased at a higher SOC?
3. I think thas a ~200kwh bummer, which matches with 99kwh after 50% charged.
