For CAN based systems, the states can be commanded through the
HOST_stateRequest Signal in the HOST_batteryRequest Message (0x502). The Drive
and Charge states allow current to flow in and out of the battery. The Standby and
Standby Not Ready states indicate that the BMS is awake but not delivering power,
either by the None command or because there is a fault in the system preventing the
power to/from the battery. The Sleep state is a low power state the BMS will enter when
given the sleep command or when CAN communication has ceased for approximately 5
seconds. (Note: if the Sleep command is initiated, CAN communication must be
terminated immediately afterward, otherwise the system will wake due to CAN traffic).

Operation State Actions
Host Request Reaction
None
No Power Delivery, FET (Circuit Breaker will be Open)
Drive
Power Delivery, Circuit Breaker will be Close (Normal
Operation)
Charge
Power Delivery, Circuit Breaker will be Close (Mainly for
Charger)
Sleep
No Power Delivery, Circuit Breaker will Open (shutdown the
BMS)
In IGN-based Wakeup operation, the BMS will default to the Drive state if there are no
faults present, and power will be allowed to flow through the terminals. If a fault is
present the BMS will stay in the Standby Not Ready state until the fault condition has
cleared. The BMS will enter sleep state within 5 seconds of the Ing Low signal being
removed.
