Abstract

A battery charging and discharging system includes bidirectional power supply and bypass module. Bidirectional power supply provides a charge current to charge a battery in a charge operation. Bypass module includes a first current path and a second current path that are coupled in parallel to each other. First current path includes a first resistor unit and battery coupled to first resistor unit. Second current path includes a second resistor unit. Charge current is a sum of a first charge current flowing through first current path and a second charge current flowing through second current path. Impedances of first resistor unit and second resistor unit are adjusted to gradually increase and to decrease respectively, so that a current value of first charge current gradually changes from a first current value to zero and a current value of second charge current gradually changes from zero to a second current value.
