Abstract

The invention provides a storage battery pack and a control method thereof, the storage battery pack comprises a plurality of battery units and a plurality of power units; the battery units are connected in series; each battery unit is provided with at least one power unit; and the power units are used for adjusting the charging and discharging electric quantity of the corresponding battery units so as to balance the voltage of each battery unit. Therefore, the technical problem that the service life of the storage battery pack is short due to different charging capacities and non-uniform charging voltages of different battery units and power units is solved.

Description

technical field [0001] The invention belongs to the technical field of battery packs, and more specifically relates to a battery pack and a control method thereof. Background technique [0002] The energy storage battery pack is composed of multiple single battery cells connected in series. At present, the battery pack has been widely used in electronic equipment in the fields of transportation, electric power, and communication. Practice has shown that when the battery is combined into a unit, its life is far lower than that of a battery unit. The fundamental reason is that the current flowing through each single battery unit is the same in the charging equipment for charging the battery unit. However, due to the difference in the capacity of the single battery cells, when the same charging current flows through the charging equipment of the battery pack, the charging will cause some single battery cells to be fully charged, and some single battery cells will appear overcha...
