Abstract: A battery charge-discharge path management circuit and method thereof are provided. The battery charge-discharge path management circuit is coupled to a battery module and an electronic device. The battery charge-discharge path management circuit includes a first determination circuit, a second determination circuit and a switch circuit. The first determination is for determining whether the battery module and the electronic device are in a charge status or in a discharge status at the same time. The second determination circuit is for determining whether the electronic device is coupled to the battery module. The switch circuit forms a charge-discharge path between the battery module and the electronic device both if the battery module and the electronic device are in the discharge status or in the charge status at the same time and if the electronic device is coupled to the battery module.

Abstract: A battery module and a charge/discharge method thereof are provided. The battery module comprises a cell, a charge/discharge circuit, a temperature sensing circuit and a charge/discharge speed controlling circuit. The charge/discharge circuit is coupled to the cell. The temperature sensing circuit further comprises a temperature coefficient (PTC) device used for sensing a temperature of the cell, so that the temperature sensing circuit outputs a first analog signal according to the temperature of the cell. The charge/discharge speed controlling circuit, according to the first analog signal, outputs a control signal to the charge/discharge circuit to adjust a charge/discharge speed of the cell.
