PROBLEM TO BE SOLVED: To provide a power supply system for vehicles that can perform serial/parallel connection as in a prior art, can reduce the number of charge resistors and switches to be connected, and can reduce the costs of a configuration circuit. SOLUTION: The power supply system for vehicles comprises: first and second power storage means 11, 12 electrically connected to an inverter 4 connected to a motor 5; a first switch means 22 arranged in a circuit for connecting the power storage means to the inverter in series; second switch means 24, 25 arranged in a circuit for connecting the power storage means to the inverter in parallel; a third switch means 21 connected in parallel with the first switch means and one charge resistor 3 for suppressing an abnormal current; a fourth switch means 23 that is branched from the area between the third switch means and one charge resistor and is arranged in a circuit for connecting one power storage means to the inverter via one charge resistor; and a control means 9 for controlling the operation of each of the plurality of switch means.
