Battery with circuit breaking function

Abstract

The invention discloses a battery with a circuit breaking function. The battery comprises a battery body. A positive terminal of the battery body comprises a first sub positive terminal and a second sub positive terminal. The first sub positive terminal is connected with the battery body, and the second sub positive terminal is erected on the first positive terminal through a positive frame. A negative terminal of the battery body comprises a first sub negative terminal and a second sub negative terminal. The first sub negative terminal is connected with the battery body, and the second sub negative terminal is erected on the first sub negative terminal through a negative frame. A connecting piece, springs, an electromagnet and a temperature difference battery are further included. The connecting piece is connected with the positive terminal and the negative terminal through the springs. The electromagnet is installed on the battery body and located below the connecting piece, and the attraction end of the electromagnet just faces the connecting piece. The electromagnet is connected with the temperature difference battery, the hot end of the temperature difference battery stretches into the battery body, and the cold end of the temperature difference battery is located outside the battery body. The battery is cut off from the source, and the battery automatically breaks a circuit when the internal temperature of the battery is too high.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery with a circuit breaker function. Background technique [0002] As we all know, during the use of the battery, its working temperature fluctuates widely, and in different temperature environments, the performance of the battery is also different. Among them, when the battery is in a high temperature state, the activity of the battery is very high. The energy density that can be stored and released is also very large, but its heat generation also increases, which seriously affects the life of the battery, and when the heat generation increases to a certain extent, the internal temperature of the battery will be too high. The danger of explosion or fire, therefore, existing batteries all have certain danger. [0003] Although it is possible to reduce the possibility of battery high-temperature explosion by cooling the battery, there are still certain limitations in its ...

Among them, when the battery is in a high temperature state, the activity of the battery is very high. The energy density that can be stored and released is also very large, but its heat generation also increases, which seriously affects the life of the battery, and when the heat generation increases to a certain extent, the internal temperature of the battery will be too high. The risk of explosion or fire, therefore, the existing batteries have a certain degree of danger

[0003] Although it is possible to reduce the possibility of battery high-temperature explosion by cooling the battery, there are still certain limitations in its predictability or response to temperature. Without quick relief, the battery could still explode
