Abstract: After the highest voltage of a rechargeable battery becomes higher than 4.0 V, when the charging current keeps lower than 50 mA for 20 seconds, a first point is detected for stopping charging the battery. Also, after the highest voltage becomes higher than 4.0 V, the charged capacity value and the discharged capacity value are added and subtracted for integrating the charged/discharged capacity if the highest voltage keeps higher than the integration start voltage. When the integration result shows that the battery is charged totally after the highest voltage becomes higher than 4.0 V, and when the absolute value of the integration result becomes larger than 50% of the designed capacity of the battery, the point second is detected for stopping charging the battery.

A battery temperature when the battery is charged to a second predetermined capacity is predicted based on the gradient. A charging current is controlled based on the predicted temperature. The battery is charged, at a current that results in a temperature of the battery that is lower than the predetermined temperature, to the second predetermined capacity.
