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