Aspects acquire at least one first battery state when a battery of the electronic device is in a first dormant state; acquire at least one second battery state of the battery in a second dormant state and the charge level or discharge capacity of the battery during the first dormant state and the second dormant state when it is confirmed that the battery enters the non-dormant state from the first dormant state, and enters the second dormant state from the non-dormant state; and calculate the actual full charge level of the battery on the basis of at least the first battery state, at least the second battery state and the charge level or discharge capacity. The technical problem that the calibration of battery capacity can only be conducted in a full charged state for the battery existing in the electronic device in prior art is solved by the above-mentioned technical solution provided in the present invention.

Aspects for determining charging capacity of a battery

A method includes detecting a present temperature value of a battery cell of a battery, determining whether the present temperature value is higher than a lowest threshold temperature value and lower than a highest threshold temperature value, detecting a present electric current value of the battery in association with a determination that the present temperature value is higher than the lowest threshold temperature value and lower than the highest threshold temperature value, determining whether the present electric current value is higher than a threshold current value corresponding to the present temperature value, and stopping a charge-discharge process of the battery cell in response to determining that the present electric current value is higher than the threshold current value.

Method and apparatus for controlling battery cell charging-discharging

Disclosed are charging control methods for a rechargeable battery and portable computers. The charging control method includes acquiring a control parameter for a charge current of the rechargeable battery; modifying, based on the control parameter, the charge current from a first charge current to a second charge current less than the first charge current; and charging the rechargeable battery with the second charge current. Compared with conventional methods of charging the battery always with the maximal charge current, the present disclosure can improve the battery's lifetime.

Charging control method for a rechargeable battery and portable computer
