While "Total charge-" constantly increases during battery operation, SOH will be linearly decrease at the same time. This mode requires a confirmed data about cell health depending of amount of discharge rate to configure the linear function.

677 677  
678 678  Since the series of cells can operate at different loads, they must be balanced. For this, the BMS Main 3 provides two signals to power switches: “Balancing series 1” and “Balancing series 2”, as well as a combined algorithm that considers both the voltage of each series and the charge that these series gave load. The “Balancing series 1” and “Balancing series 2” signals are used to connect high-power balancing resistors in parallel with cell series 1 and 2.
