Battery information
The vehicle is composed of a high voltage battery that drives the motor, air conditioner, and charges an auxiliary battery (12 V) that drives all other 12 V systems.
The auxiliary battery is automatically charged when the vehicle is in READY mode or the high voltage battery is being charged.
NOTE
What does regenerative braking do?
It uses the electric motor when decelerating and recaptures & transforms kinetic to electrical energy in order to charge the high voltage battery.
