A 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 state or in a discharge state 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 state or in the charge state at the same time and if the electronic device is coupled to the battery module.
