Curious about the systems page? Here's a TLDR of the data it contains.
SoC (HV) - State of Charge of the high voltage battery. This is the one being used to drive the motor and HVAC systems.
SoC (LV) - State of Charge of the low voltage battery. This is the one being used to drive the instruments, lights and other accessories.
Charger - This indicates the state of the vehicle charger.
DC-DC - This is what converts power from the high voltage battery to the low voltage one. In an electric vehicle, this replaces what would traditionally be the alternator.
HVAC Temp / Mode - This indicates the temperature and state of the cooling and heating system for the battery and motor.
