Abstract
A power source apparatus mounted to a vehicle is equipped with a lead-acid battery and a lithium battery. An open circuit voltage and an internal resistance of each of the batteries are determined to satisfy the following conditions (a), (a), and (a): (a) In the use range of SOC of the lead-acid battery and the use range of SOC of the lithium battery, there is an equal voltage point Vds at which the open circuit voltage V(Pb) of the lead-acid battery becomes equal to the open circuit voltage V(Li) of the lithium battery; (a) The relationship of V(Li)>V(Pb) is satisfied in the upper limit side of the use range of SOC of the battery; and (a) A terminal voltage Vc (Li) of the lithium battery is not more than a set voltage Vreg of a regulator when a maximum current flows in the lithium battery.
