Abstract: A method for measuring electric charge of a battery is provided. The method includes the following steps. A lookup table is provided that stores a plurality of preset measurement confirmation voltages and a plurality of set electric charge. A first voltage of the battery is measured as a start point. An end point is calculated according to the lookup table and the start point. A voltage and a current of the battery are measured until a measured voltage reaches a preset measurement confirmation voltage corresponding to the end point. A set electric charge is calculated according to the lookup table from the start point to the end point. An actual electric charge is calculated from the start point to the end point. The set electric charge is corrected according to a difference between the actual electric charge and the set electric charge.
