Comment on BYD announces charging tech that’s twice as fast as Tesla’s

Wow, 1 MW surpasses a lot (most?) of lighting based superhero/supervillains (def the shitty ones like Vader, but also orders of magnitude from TWs in Thors sparklers?).

This is a totally normal thought to have whilst charging up your car, shut up.

Darth Vaders’s main power was not lightning, but telekinesis. I’d bet he would have a greater output spinning one (or more) industrial generators.

  Oh, good thinking, yeah! Lol
  (Also that is how force users would be used irl.)
  
  There is also the whatever amount of power (fields?) was used for constant healing & prolonging life by Palpatine for himself & his lil puppy (Vader in my previous msg was a brainfart, I prob meant Sidious, but same diff … can’t brain today no more).
  
  I bet this could be modified to make electricity via some chemical processes.

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.

  Yeah but imagine the BMS you’d need for 1MW to not have everything immediately go to hell, especially as your math puts you at 1,000 volts, 1,000 amps. You can make cables that big, and perhaps that will become standard, but this is a bit beyond comprehension with current tech.

    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).

    I’m using 8AWG from the solar for 1,200W. While it may be overkill, well, one doesn’t want to start a fire in a van. That runs about 80A, so I’d likely be fine smaller, but 1,000 amps being “just” a centimetre is something of an absurd claim. I suppose compared to gas pumps, it’s tiny!

  Oh, yeah, I understood that - it was the fact that this is for the everyday “consumer” (for consumers) tech that inspired the comment, that regular folk will get up & personal with such tech soon & make it a regular mundane chore.
  
  I could think about how much electricity an electric plant produces (& couldn’t comprehend it in daily terms that would make sense), but sitting in a charging car you get a much clearer picture of what that means, of how much energy (and “how much driving”) is running through that cable every second, etc.
