Hi Folks
EVs have their own onboard chargers, essentially a 85-264V switching power
supply. The off board EVSE is a microprocessor communication board and a
contactor. No charger off board. The EV senses 120 or 240V applied and sets
the PWM on the charger appropriately to draw typically 12 amp
Tesla modules are 6s configuration or 25.2 volts. 5 modules is 126 volts.
Calbs are 3.65 end of charge or 175volts.
If you can reduce the voltage it may work.

The housing might be special but I bet the gears are front axle from
an AWD of that era. Only a few manufacturers of hypoid gears are out
there, less than in the '90s. I bet if you took them out you c

Self-heating helps; but it's not much unless you are discharging the
batteries pretty quickly (like a full discharge in less than an hour).
The heat from internal resistance is proportional to I^2R, so hi
One good idea that was mentioned by the Now You Know Youtube channel was to
use waste energy from regenerative braking to heat the battery (e.g. instead
of dumping power into the battery which is usually limited by either high
SoC or low battery temperature, or just battery charge rate limit, dump
