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.
