Deactivates history based balancing.
The balancing state of all cells in all strings set to inactivate (that is 0) and the delta charge is set to 0 As. The balancing enable bit is deactivate (that is 0).
Definition at line 158 of file bal_strategy_history.c.
STD_RETURN_TYPE_e BAL_GetInitializationState | ( | void | ) |
gets the initialization state.
This function is used for getting the balancing initialization state

State machine subfunction to balance the battery cell
Definition at line 211 of file bal_strategy_history.c.

static |
State machine subfunction to check if balancing is allowed.
Checks if balancing is allowed. If it is it transfers in the actual balancing state.
Definition at line 172 of file bal_strategy_history.c.
BAL_RETURN_TYPE_e BAL_SetStateRequest | ( | BAL_STATE_REQUEST_e | stateRequest | ) |
sets the current state request of the state variable bal_state.
This function is used to make a state request to the state machine, e.g, start voltage measurement, read result of voltage measurement, re-initialization. It calls BAL_CheckStateRequest() to check if the request is valid. The state request is rejected if is not valid. The result of the check is returned immediately, so that the requester can act in case it made a non-valid state request.

Definition at line 308 of file bal_strategy_history.c.
void BAL_Trigger | ( | void | ) |
trigger function for the BAL driver state machine.
This function contains the sequence of events in the BAL state machine. It must be called time-triggered, every 100 milliseconds.
