A motor-generator system mainly performs motor control to provide motive power and also controls regeneration by the motor acting as a generator. Advances aimed at lower fuel consumption and reduced CO2 emissions are being made constantly in motor and regeneration control, and they require MCUs with high performance and advanced functions.
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.
A charger and DC/DC step-up system controls the AC input from the household power supply and boosts the voltage to that required by the battery using a DC/DC circuit. The MCU performs both Power Factor Correction (PFC) control and control of the DC/DC step-up circuit.
