PROBLEM TO BE SOLVED: To solve the problem, that, when a plurality of batteries are connected in parallel to a power supply circuit to be discharged in parallel with each other, voltages of the respective batteries may different. SOLUTION: When a plurality of batteries are connected in parallel with each other with switching means corresponding to the respective batteries and an information processor is made to operate by discharge currents of the batteries charged by a charging current supply means, the voltages of the plurality of batteries are compared with each other by a comparison means, and if the voltage of one battery is lower than the voltage of the other battery by a prescribed value or more, a control means turns off the switching means corresponding to the other battery and cuts off the parallel connection. |
