Abstract
The utility model discloses a reverse-resistant storage battery combinational circuit which comprises a storage battery, a diode, a radiator, a bolt and a nut. The reverse-resistant storage battery combinational circuit is characterized in that: in the storage battery combinational circuit, the anode of the storage battery is connected with an external circuit; the cathode of the storage battery is connected with the anode of the diode with the radiator by the bolt and the nut; and the cathode of the diode, which is used as the cathode of the combinational circuit, is connected with the external circuit. During specific use, a charging circuit is connected with the anode and the cathode of the combinational circuit; the positive input end of a back-end load is connected with the anode of the combinational circuit, and the negative input end is connected with the public end of the anode of the diode and the cathode of the storage battery; the storage battery combinational circuit replaces the conventional single storage battery to be used in the circuit; and when the anode and the cathode of the storage battery combinational circuit are connected oppositely, the storage battery does not damage the system due to the blocking function of the diode. The circuit has a simple structure, and the storage battery combinational circuit is formed only by the storage battery and the diode with the radiator; even if the anode and the cathode of the combinational circuit are connected oppositely, the whole system is not damaged; and the circuit has relatively good use value.
