A battery charger that can automatically identificate the battery polarity, includes a state/polarity identification module (200), a controller (300) and a rechargeable drive unit (100). Wherein the state/polarity identification module (200) automaticlly identificates the unladen, short-circuit, over-current, positive battery connecting, and reverse battery connecting condition of the charger, and detects the state of the battery, so as to generate the corresponding state signal; the controller (300) controls the switching action of the rechargeable drive unit (100) according to the state signal, thus choosing the correct charging circuit and the charge current, and reaching rechargeable function of battery inverse. The circuit is integrated into a chip and greatly reduces the circuit costs.
