Abstract

PURPOSE:To prevent the breakdown of electronic parts due to reverse voltage, by precluding a storage battery from being connected to the output side of a main power source when the storage battery is connected in reverse by mistake. CONSTITUTION:A storage battery B is charged by a main power source A and supplies a DC output to a load when the output of the main power source A is stopped. An overdischarge preventing means C connects the storage battery B to the output side of the main power source A in accordance with the output of the main power source A while cuts the storage battery B off from the load when the output of the storage battery B has reduced to a value lower than a predetermined value. A polarity deciding means D decides an abnormal connection from the polarity under the connecting condition of the storage battery B and precludes the storage battery B from being connected to the output side of the main power source A whereby the storage battery B may be connected to the output side of the main power source A only when the connection of the storage battery B is normal.
