Description

Technical Field

[0001] The utility model mainly relates to the technical field of energy storage batteries, and in particular to an energy storage battery with a low-temperature heating function. Background Art

[0002] With the development of energy storage technology, the application scope of low-temperature heating energy storage systems will continue to expand. In addition to being able to provide emergency backup power for important facilities such as emergency rescue for natural disasters such as epidemics, earthquakes, and ice disasters; different battery packs have different designs, and their internal and external structural designs, module connection methods, and process technologies are different; this means that it is impossible to use a set of disassembly lines to suit all battery packs and internal modules. When the battery is disassembled and started for use, flexible configuration is required, and the disassembly line is divided into sections and refined. For different battery packs, when formulating the disassembly operation process, the sections and processes of the existing assembly lines should be reused as much as possible to improve work efficiency, reduce duplicate investment, greatly improve the utilization efficiency of the starting battery power supply, and reduce resource consumption.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] Most of the common self-heating lithium batteries on the market currently heat the lithium battery directly by attaching a heating plate to the lithium battery and activating the heating plate through a temperature sensor when the temperature is too low. However, directly activating the heating plate to heat the lithium battery can easily cause the lithium battery to overheat. In order to avoid heat loss, most lithium batteries with low-temperature self-heating functions are also provided with a heat insulation layer to prevent the heat of the lithium battery from being quickly absorbed by the surrounding environment. When the lithium battery itself is running, it will generate more heat, and the lithium battery will be easily damaged if it overheats. Patent application number 202210511254.4 discloses a lithium battery with low-temperature self-heating function, including: a main body, a lithium battery body arranged inside the main body to store electrical energy, and a heat insulation plate is arranged around the lithium battery body inside the main body. This type of lithium battery uses a heat insulation plate to isolate the lithium battery body, reduce the temperature conduction between the lithium battery body and the outside world, and thus prevent the lithium battery body from being overcooled quickly. When the lithium battery is overcooled, the conduction component cooperates with the heating component in the heating chamber to heat the lithium battery with steam conduction. On the one hand, it can improve the uniformity of heating, and on the other hand, it can prevent the heating plate from directly heating and causing overheating and damage to the lithium battery body. At the same time, when the temperature of the lithium battery body is too high, the heat dissipation component can be adjusted to dissipate the heat of the lithium battery body through the heat dissipation component to avoid overheating and damage to the lithium battery body. Although this application uses steam conduction heating for lithium batteries, steam is misty and contains water after all. Steam is easy to adhere to the lithium battery, resulting in water vapor on the lithium battery, affecting the normal use of the lithium battery.

A plurality of vents 301 are evenly opened on the inner wall of the movable box 3, and the exhaust components heat the lithium battery body 4 through the heating plate 5 and the vents 301.
