ABSTRACT:
A protecting apparatus protects an electronic device which is provided on a vehicle having a storage battery and a solar battery and which inputs output voltages of the storage battery and the solar battery to the electronic device. The protecting apparatus includes a voltage determining unit for determining whether or not the output voltage of the storage battery is normal, an interruption unit for interrupting a path from the solar battery to the electronic device, and a control unit for controlling the interruption unit and thereby interrupting the path when the voltage determination unit determines that the voltage of the storage battery is not normal.
