Beschreibung
Zusammenfassung:	The invention discloses a battery pack maintenance method. The method comprises the following steps of: detecting a connection state of a battery pack and a charger, judging whether the battery pack is in a first state or a second state, and setting a first parameter according to a judgment result; measuring the voltage of single batteries in the battery pack; judging the voltage of the single batteries in the battery pack, taking the maximum voltage of the single batteries as a first voltage, and taking the minimum voltage of the single batteries as a second voltage; searching a battery health state table according to the first parameter, the first voltage and the second voltage, and outputting a health parameter and a current state of the battery pack; and when the health parameter is lower than a threshold value, maintaining the battery pack. According to the method, by means of setting, the voltage of the single batteries in the battery pack is detected and the range of the voltage is evaluated, the healt
