Nickel-cadmium storage batteries and nickel-hydrogen storage batteries have different charging currents. That is, the nickel-cadmium storage battery has a charging current of 500 mA, whereas the nickel-hydrogen storage battery has a charging current of 500 mA, so the nickel-cadmium storage battery and the nickel-hydrogen storage battery must be charged separately. I won't. Therefore, in this embodiment, as shown in FIG. 1, the nickel-cadmium storage battery C and the nickel-hydrogen storage battery H share the same position of the charging terminals C1 and H1 on the negative electrode side, but on the positive electrode side. The positions of the charging terminals C2 and H2 were shifted. Further, in the nickel-hydrogen storage battery, the temperature characteristics change abruptly with a certain temperature as a boundary, so it is necessary to stop charging when the temperature exceeds a predetermined temperature. Therefore, it is necessary to monitor the battery temperature.
