balance()

void balance	(	BMSConfigStructTypedef const *	cfg,
		BMS_critical_info_t *	bms,
		CellData	bmsData[144],
		bool	cellDischarge[12][12],
		bool	fullDischarge[12][12],
		uint8_t	balanceCounter,
		uint8_t *	chargeRate )

This function is still a work in progress.

setCriticalTemps()

void setCriticalTemps	(	BMS_critical_info_t *	bms,
		CellData const	bmsData[144] )

This method calculates the maximum and minimum cell temps in the pack, and sets those values w/ the associated cell number to the bms critical info struct.

Parameters

cfg	is the bms configuration file with constants used in our bms
bms	is the bms struct that contains critical info regarding our pack
bmsData	is an array of 144 cellData structs, containing index, fault, voltage and temperature

Returns

none
