Messages and Signals

This section provides information on the CAN bus messages and signals used in the ProhelionBmsD1000Gen2. Each message is identified by its unique ID, and the structure, including signals, is described.

Note! "Default BASE ID" The following Message IDs assume a default CAN Bus BASE ID of 0x600. The BASE ID of each device is configurable via the device configuration. If the BASE ID has been configured differently on the device, make sure to account for the shift in the Message IDs. The Message ID offsets from the BASE ID will remain the same regardless of the device configuration.

Name Comment Unit Start Bit Length Signed Scale Offset Min Max Byte Order
BMSStateINIT Initialisation state. Immediately enters this state on startup and proceeds to CALIBRATE once the conditions are met 0 1 False 1 0 N/A N/A little_endian
BMSStateCALIBRATE Calibration state. Ensures contactors are open before moving to the SAFE state. 1 1 False 1 0 N/A N/A little_endian
BMSStateIDLE Idle state. System is healthy and awaiting a command to enable or charge. 2 1 False 1 0 N/A N/A little_endian
BMSStateCONNECT Connect state. A request has been made to close the load contactors. The negative contactor to the load has been closed to enable load voltage checks. 3 1 False 1 0 N/A N/A little_endian
BMSStatePRECHARGE Precharge state. The precharge contactor is closed. 4 1 False 1 0 N/A N/A little_endian
BMSStateENABLED Enabled state. Contactors to the load are now closed following a successful PRECHARGE state. This state will persist until commanded otherwise, or a fault occurs. 5 1 False 1 0 N/A N/A little_endian
BMSStateCHARGE_INIT Charge initialise state. Initialises the charge session, including EVCC for EVSE charging if configured. Waits for Charge Enable Command to proceed 6 1 False 1 0 N/A N/A little_endian
BMSStateCHARGE_CONNECT Charge connect state. Closes the negative charge contactor and checks that battery and charger voltages match before proceeding 7 1 False 1 0 N/A N/A little_endian
BMSStateCHARGE_ENABLED Charge enabled state. Closes the positive charge contactor, allowing the charger to deliver current to the battery 8 1 False 1 0 N/A N/A little_endian
BMSStateCHARGE_STOPPING Charge stopping state. Waits for current flow to reduce before opening the contactors and performing welding detection 9 1 False 1 0 N/A N/A little_endian
BMSStateDISCONNECT Safe disconnect state. This state is a transitionary state to allow current flow to stop prior to opening the contactors in the SAFE state. This state occurs if an error has occurred while contactors are closed 10 1 False 1 0 N/A N/A little_endian
BMSStateSAFE Safe state. An error has occurred or we have progressed from the CALIBRATE state. The SAFE state ensures the battery is disconnected from the load and will transition to IDLE state after all errors have cleared. Latching errors will require a reset before the BMS will leave SAFE state 11 1 False 1 0 N/A N/A little_endian
BMSPrechargeFailTIMEOUT Timeout issue. State has timed out waiting for successful completion of the precharge process 16 1 False 1 0 N/A N/A little_endian
