Abstract:
A power supply system that is mountable on a vehicle has a lead-acid storage battery connected to an electrical load, a lithium-ion storage battery having different charge and discharge characteristics form the lead-acid storage battery, and connected in parallel with the lead-acid storage battery with respect to the electrical load, a power generator configured to charge the lead-acid storage battery and the lithium-ion storage battery, and a controller configured to drive the power generator based on a relationship between a discharge current of the lead-acid storage battery and a discharge current of the lithium-ion storage battery.
