Device, method, and electronic equipment used for managing battery abnormity

Abstract

The invention discloses a device, a method, and electronic equipment used for managing battery abnormity. The device is used for managing abnormity of a battery pack. The battery pack comprises a plurality of battery modules; the device comprises a detecting unit, a determining unit and a processing unit; the detecting unit comprises a plurality of first thermistors; the plurality of first thermistors are arranged on the two ends of each battery module of the battery pack, and are used for detecting temperature information of the two ends of each battery module of the battery pack; the plurality of first thermistors comprise a thermistor group or a plurality of thermistor groups which are formed by parallel connection of a plurality of second thermistors; the determining unit and the detecting unit are coupled, and are used for detecting that wheather a corresponding battery module of the battery pack is abnormal so as to determine that whether the battery pack is abnormal based on parallel resistances of the thermistor groups; the processing unit and the determining unit are coupled, and are used for execution of abnormity managing operation when the battery pack is determined to be abnormal by the determining unit. The device, the method, and the electronic equipment are capable of prolonging service lift, and reducing spontaneous combustion rate of batteries.

Description

technical field [0001] The invention relates to the electrical field, in particular to a battery abnormality processing device, method and electronic 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 as an example, for every 1 million electric vehic...
