The invention provides an apparatus and a method for processing battery abnormity, a battery system and electric equipment, so as to overcome the problems of short battery service life and / or battery self-combustion rate in conventional battery packs. The apparatus for processing the battery abnormity comprises a detection unit for detecting temperature of the battery pack, a determination unit for determining that the battery pack is abnormal when the temperature is abnormal and a processing unit for executing abnormal processing operations when the battery pack is abnormal. The battery system comprises the battery pack and the apparatus for processing the battery abnormity. The electric equipment comprises the above battery system. The method for processing the battery abnormity is used for executing treatment for realizing the functions of the apparatus for processing the battery abnormity. By applying the apparatus and the method for processing the battery abnormity, the battery system and the electric equipment, abnormal problems of the battery such as looseness and / or thermal runaway of the battery can be found and solved in time, so that the service life of the battery can be prolonged and the self-combustion rate of the battery can be reduced, and thus the service life of the electric equipment can be prolonged and the self-combustion rate of the electric equipment can be reduced.
Description
technical field [0001] The present invention generally relates to the electric field, and specifically relates to a battery abnormality processing device and method, a battery system, and electrical equipment. Background technique [0002] At present, storage batteries are widely used in electrical equipment such as electric vehicles and various portable equipment. However, once the battery connection becomes loose and / or thermal runaway occurs, the temperature of the battery will rise during charging, causing a large amount of water loss and swelling of the battery, which will shorten the life of the battery and may even cause the battery to spontaneously ignite. When discharging, the loose connection of the battery will cause thermal imbalance and shorten the life of the battery. When the temperature is too high, it will cause the spontaneous combustion of the connecting wire, which in turn will cause the battery to spontaneously ignite. [0003] Taking electric vehicles ...
