Problems solved by technology

[0002] With the continuous development of science and technology, our country has entered the era of new energy. As we all know, power lithium batteries have been widely used in the field of new energy. At present, the normal working temperature range of power lithium batteries on the market is 0-50 degrees Celsius. In this case, if the charging and discharging performance of the power lithium battery is very poor in winter or when the ambient temperature in the north is low, you can only choose to heat the lithium battery to make it work normally. Battery heating generally has the disadvantages of complex heating device structure, high cost, and low heat exchange efficiency, which directly affects the normal operation and service life of power lithium batteries
