Abstract: Provided herein is a charger having a battery diagnosis function. The charger is connected between an input power supply supplying an input voltage and a battery and charges the battery with the input voltage. The charger includes a full-bridge-circuit connected to the input power supply and comprising a first switch, a second switch, a third switch, and a fourth switch, a transformer including a primary winding and a secondary winding, wherein the primary winding is connected to the full-bridge-circuit to transform the input voltage received from the full-bridge-circuit and transmits the voltage to the secondary winding, and a rectifying circuit comprising a fifth switch and a sixth switch, connected between the secondary winding and the battery, and rectifying the voltage received from the transformer to charge the battery, or transmitting power in two directions for diagnosing a state-of-health of the battery.
