Operation of Chaos

Power On

Driver switches car on, closes connection between aux battery and Chaos
Chaos turns Plutus on
If no faults are detected by Plutus, battery relay and solar relay closes
Chaos checks if DC-DC is functional, if so, switch power to DC-DC. This will also power all other LV components of the vehicle. If not, Chaos will go into a fault state, possible DC-DC failure
Chaos will initiate pre-charge, and wait for the main relays to close via the sense wires
If main relay closes, car is now ready to drive. If either doesn't, Chaos goes into another fault state, possible pre-charge or relay failure

Driver switches car off
Chaos turns Pre-Charge off, main relays open and vehicle goes into discharge. If the main relays fail to open, a relay fault will be raised
Chaos opens the solar relay, and battery relay
Chaos and Plutus is now powered by the aux battery
The vehicle is now off
The aux battery can be disconnected through another switch

If kill switch is hit at any point, chaos will open all relays. Since the DC-DC is now off, pre-charge will open the main relays.
