Battery polarity automatic detection device uses detector units to detect positive voltage that connects the positive poles of the detector device to the detector terminals and positive poles of the battery

摘要

A battery is connected with the detector terminals (D) of a detector circuit. If the detector terminals are connected to positive poles of the battery, the detector units (E) detect positive voltage that actuates an electrical connection with the positive voltage electrical connecting units (F) and connects the positive poles of the detector device to the detector terminals and to the positive poles of the battery. The detector units determine negative voltage and actuate a connection with the negative voltage electrical connecting units (G) to form a complete circuit.
