A battery control system is used for managing remaining battery capacity and control of battery charging and discharging. The voltages of the individual cells are monitored, and the balance controlled by the lithium-ion battery cell monitor ICs. The battery management MCU provided by Renesas can perform management of remaining battery capacity and battery charge control. In addition to the battery management MCU, Renesas supplies analog and power devices suitable for battery control systems.
