Abstract

An electric power source system for a vehicle includes a lead-acid battery electrically connected with the starting device in parallel as a first storage battery, a second storage battery electrically connected with the starting device in parallel, a switch device disposed between the lead-acid battery and the second storage battery on an electrical path connecting the lead-acid battery with the second storage battery, at least one electrical load electrically connected to the electrical path and disposed closer to the lead-acid battery, and a switch controller controlling the switch device to maintain a closed state except an engine start duration while the engine is being started by a starting device after a power of the vehicle is turned on.
