While this generalization is true, L2 charging the FFE at 6.6kW is still a "slow charge" relative to the battery size and capabilities. Considering the 23kWh pack, 6.6kW charging is only putting 20.7A into the 75Ah rated battery. That's only charging at 0.28C which is still slow charging. I"m not familiar enough with the Lithium NMC battery chemistry to know what it's upper charging limits are but I'm I would think charging at 1C (23kW) would not not harm the battery although you'd probably want to slow the charge rate as you approach a full battery.Pearl wrote:Faster is not really better with charging. Faster charging means more current, means more heat, means more harmful to the battery.
Out of curiosity I measured the amps going back into the battery under heavy regen and IIRC it topped out at a little north of 130A which is just less than 2C. Granted that regen is just short pulses into the battery and I don't know what charge rate would be considered bad for the battery chemistry, I mentioned it here for illustration that regen rates are many times what you normally charge at.
