Main Functionalities

• Check the status of AUX Battery

  • Voltage

  • Temperature

• Check the status of DCDC

...

• needs to communicate with the:

  • front end distribution

  • rear end distribution

  • BMS Carrier?

Modules:

• power_selection_fsm:

  • tells if the power selection board is on/off

• power_selection_fault_monitor:

  checks for faults across the boards

  • centre console

• DCDC sends a message

  • Confirm ack status

  • I acknowledge it and turn on

  • Confirm DCDC status

• when receive can message, there’s a pointer, and then set that point to the ACK message

Modules:

• aux_dcdc_monitor_init

  • It periodically checks aux voltage and temp, and broadcasts it over CAN

  • CAN_TRANSMIT_AUX_BAT_DATA(u16 temp, u16 volt, u16 status )

    • First bit of status is aux ov

    • Second bit is aux uv 

    • Third bit is aux ot 

    • Fourth bit is aux ut

    • Fifth bit is dcdc (is on main if set)

  • It also responds to CAN_TRANSMIT_POWER_ON_MAIN_SEQUENCE

    • Do a check and then set the ack_reply
