Abstract

The invention discloses a softly packaged energy storage battery. The softly packaged energy storage battery comprises battery packs, a control unit and a protection box body; each battery pack comprises a cell, a protection frame, a protection cover, a cell protection plate, a temperature acquisition unit and a temperature adjustment unit; the cell is fixedly arranged in a region formed by the protection frame in a surrounding manner; the protection cover covers the protection frame and is fixedly connected therewith; the cell protection plate is arranged between the protection cover and thecell; the temperature acquisition unit is arranged at one end of the protection frame; the temperature adjustment unit is arranged on the external top wall of the protection cover; the number of the battery packs is two or above, and the battery packs are fixedly arranged in the protection box body; and the control unit is fixedly arranged in the protection box body, and electrically connected with the battery packs. By virtue of the additional temperature acquisition unit and the temperature adjustment unit, the internal real-time temperature of the energy storage battery can be monitored, and the internal temperature of the energy storage battery can be adjusted according to temperature values, so that the working state of the energy storage battery can be ensured at different temperatures, the applicable environment of the energy storage battery can be wider, and higher convenience is achieved.

Description

technical field [0001] The invention relates to the field of battery packs, in particular to a soft pack energy storage battery. Background technique [0002] Energy is a subject related to the lifeline of the country and is related to the sustainable development of the country. Soft pack battery pack is another name for polymer battery pack. Compared with traditional lithium-ion battery packs, it has the following advantages: [0003] High safety, the structure of the soft-pack battery pack is packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack battery pack will only blow up and crack at most, instead of exploding like steel-shell and aluminum-shell batteries; Light weight, the weight of the soft pack battery pack is 40% lighter than the steel case lithium battery of the same capacity, and 20% lighter than the aluminum case battery pack; the specific energy is high, and the capacity of the soft pack battery pack is 10-15% higher than that of...
