Abstract
The utility model relates to an automatic battery polarity identification circuit, which is mainly used in battery charging and discharging equipment and is mainly used in input interfaces of equipment to make battery access more convenient. At present, battery access ports of most battery charging and discharging equipment adopt the method of fixed positive and negative polarity connection, which makes battery access very inconvenient. The automatic battery polarity identification circuit is characterized by comprising an input end, an output end, an identification module and a switching module, wherein the input end and the output end are electrically connected to the switching module, and the switching module is electrically connected to the identification module. The automatic battery polarity identification circuit has reasonable structure design and reliable performance, operators do not need to have relevant professional knowledge and do not need to distinguish an equipment interface to be connected with the positive pole of a battery from an equipment interface to be connected with the negative pole of the battery, and what they need to do is to connect two output wires of the battery to the equipment. The automatic battery polarity identification circuit of the utility model is capable of automatically identifying the polarity of batteries.
