Over discharge refers to that a battery continues to discharge for a long time duration after the discharge of the battery to a load is beyond a discharge cut-off voltage. The over discharge may cause an internal pressure of the battery to rise, and thus cause reversibility of active materials at positive and negative terminals of the battery to be damaged, and cause a battery capacity to decrease. In conventional technologies, the industry usually adopts a discharge cut-off voltage under a normal load and a longest sustainable discharge time duration of the battery under the discharge cut-off voltage as a determination basis of the voltage protection. However, the discharge cut-off voltage of the battery under different operation statuses or different discharge conditions varies. In conventional technologies, only the fixed discharge protection parameter is used as the determination basis for discharge protection. Thus, it is difficult to relatively accurately perform discharge protection. That is, conventional technologies cannot choose a corresponding determination basis for the discharge protection according to a present operation status of the battery, and thus it is difficult to relatively accurately perform discharge protection on the battery, thereby making it difficult to utilize the battery capacity to a greater degree.

In accordance with the disclosure, there is provided a method for controlling a battery. The method includes obtaining a present status parameter of the battery, and determining a discharge protection parameter according to the present status parameter for using in a discharge protection operation on the battery.
