Abstract
A method for correcting temperature of a rechargeable battery is provided. The temperature T of an adapter board of the rechargeable battery is detected by a sensor of an electronic device, and a temperature difference ΔTi between a cell and the adapter board is calculated during charging or discharging of the battery for a predetermined time period by acquiring a predetermined relationship mode. A cumulative temperature difference ΔT is calculated by accumulating the delta T value ΔTi, and a temperature value Tcell of the cell is calculated through the detected temperature T minus the accumulated temperature difference ΔT. Then, the electronic device can keep normal operation when taking the calculated temperature as the temperature of the cell.
