A charging method, comprising: detecting the capacity of a lithium battery; according to the required electric quantity and the capacity of the lithium battery, calculating a required charging state, and acquiring a charging cut-off voltage via a mapping relationship between the required charging state and an open-circuit voltage; and according to the charging cut-off voltage, charging the lithium battery so as to guarantee that the charging electric quantity is greater than or equal to the required electric quantity; alternatively, detecting the real-time electric quantity of the lithium battery; according to the real-time electric quantity and the required electric quantity, calculating to obtain the remaining charging electric quantity; according to the remaining charging electric quantity and a charging current, calculating to obtain a charging cut-off time; and according to the charging cut-off time, charging the lithium battery so as to guarantee that the charging electric quantity is greater than or equal to the required electric quantity. Therefore, the utilization rate of the capacity of a lithium battery and the service life of the lithium battery can be increased. |
