Centre console is the board which contains the main drive state logic for the entire car. When the car is off (Relays to main battery are open, and car is powered off the aux battery), this board, along with BMS carrier and power distribution are the only ones which are powered, so that they can be used to start the car.

Centre console also provides feedback on the state of the car throughCenter Console is the only driver interface. It controls all power transitions, motor output and steering lights. It also displays BMS data, vehicle speed and has LED indicators. This board is always on when the car is on.
