Bloody brilliant. I always wondered how much copper you need to step 120v all the way up to 800v for a car like the Taycan.
Also, 200kwh? Where's my It's Happening gif?
- AYBABTME 5y agoIt doesn't go from 120 to 800V, it gets reduced from a higher voltage to 800.
- jsight 5y agoI'm not sure what you mean. If you plug a Taycan into a 120V outlet, the onboard charger has to get from 120V to 800V. If you DCFC, it depends on the charger. I think EA will typically do 800V, but some have to go through an onboard DC->DC converter to get from 400V to 800V? I'm fuzzy on that last bit, though.
- AYBABTME 5y agoRight for the slow chargers, I hadn't thought this was what the GP meant. In any case the DCFC definitely don't step up 350KW of power from 120 to 800V, as that would defeat the whole purpose of using a higher voltage.
- jsight 5y agoOh... now I understand what you were getting at. That's definitely true. :)
