Hi all,

Bit of a newb question, but what is the 12v battery used for in the bonnet of the ID3?

Slightly glib answer; everything except traction and heating, which is handled by the traction battery.

Mainly startup, idle and fail safe systems such as door opening, lights, alarm, ecu power up. Also app function execution.

The heater is in excess of 3kW capacity and powered by the main batteries (220v) This is why range drops when climate/heating is on. Everything else that is normal automotive stuff and connected to the 12v wiring loom is supported with the 12v battery which is in turn charged by the main battery pack.
