, 4. From the first battery pack 1 to the load 6
In the case of power supply, the first power supply switch 3 is closed and the second power supply switch 4 is opened. Therefore, the load 6 is supplied with current from the first battery pack 1. Next, when the voltage of the first battery pack 1 becomes lower than the reference voltage, the power supply controller 7
turns the first power supply switch 3 into a closed state and closes the second power supply switch 4. Therefore, power is supplied to the load 6 from the first battery pack 1 and the second battery pack 2. The diode 5 prevents currents from flowing backwards when the first and second battery packs 1 and 2 simultaneously supply power to the load 6.

It becomes action. Further, although this embodiment has been described using two first and second battery packs, the same operation as this embodiment can be performed even if the number of battery packs is three.
