1mw chargers are proposed for trucking, and exist. A smaller battery being able to charge at 10C is the breakthrough. The cars on 1000v platform and 1086hp for $37300-$45000 announced… is a huge deal. I don’t think even expensive supercars have been announced at 1000v.
10C discharging has typically been reserved for small RC plane battery chemistries. LFP chemistries have supported charging at 10C but only with rapid degradation, compared to sane levels. Usual 30%-80% restrictions are likely to apply.
just searched for 1000a bms’s and they don’t seem ridiculously large. unlimited length cable needs under 1cm diameter copper as code. Not crazy either. And a calculator says that 10 feet would only have 4% voltage drop at 13awg (house wire size).
