A self-protected battery

Abstract

The invention provides a self-protection battery and belongs to the technical field of a battery. The battery comprises a battery main body, wherein at least one of an anode pole and a cathode pole of the battery main body is composed of two sub-poles; one of the two sub-poles is connected with the battery main body; the other sub-pole is connected with an external device; an inter-pole gap exists between the two sub-poles; the two sub-poles are connected with each other through a pole connector; the pole connector is made from a conductor material, is inserted into the sub-poles and is in sliding connection with the sub-poles; the battery further comprises a control chip, a lifting mechanism and a temperature measuring component which are arranged on the battery main body; the control chip is respectively connected with the lifting mechanism and the temperature measuring component; the lifting mechanism is located on one side of the pole connector and is connected with the pole connector; a temperature measuring end of the temperature measuring component is inserted into the battery main body. The self-protection battery can detect the temperature in the battery and can automatically break circuit when the interior temperature of the battery is ultrahigh.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a self-protecting battery. Background technique [0002] During the use of existing batteries, their operating temperature fluctuates widely, and the performance of the battery is also different under different temperature environments. Among them, when the battery is in a high temperature state, the battery can store and release The energy density is very high, but the heat generation is also very large. As we all know, the higher the temperature of the battery, the shorter the life of the battery, and when the internal temperature is too high, the battery will explode or catch fire. Therefore, how to ensure that the battery operates under the normal temperature range is an urgent need to solve in the battery industry. The problem.

[0002] During the use of existing batteries, their operating temperature fluctuates widely, and the performance of the battery is also different under different temperature environments. Among them, when the battery is in a high temperature state, the battery can store and release The energy density is very high, but the calorific value is also large

As we all know, the higher the temperature of the battery, the shorter the life of the battery, and when the internal temperature is too high, the battery will explode or catch fire. Therefore, how to ensure that the battery operates under the normal temperature range is an urgent need to solve in the battery industry. The problem

[0003] At present, the temperature of the battery is monitored by detecting the temperature outside the battery, and the temperature of the battery is cooled by adding a cooling device installed on the outside. Although this method reduces the possibility of high-temperature explosion of the battery to a certain extent, due to the external temperature of the battery and There is a certain difference in the internal temperature. Often when the external temperature of the battery is still normal, the internal temperature of the battery is already higher than the upper limit of its operating temperature range. In this case, the battery is likely to explode, so the existing external temperature detection method still has certain detection errors and limitations.
