Temperature regulating device

Abstract

The invention discloses a temperature regulating device used for regulating battery temperature. The temperature regulating device comprises a heat exchanging part and a liquid storage part and is characterized in that the heat exchanging part is communicated with the liquid storage part through a pipeline, the heat exchanging part, the pipeline and the liquid storage part form a heat exchanging medium circulating loop, the heat exchanging part is used for exchanging heat with batteries so as to regulate the temperature of the batteries, and the liquid storage part is used for storing a heat exchanging medium. The temperature regulating device has the advantages that the heat exchanging part, the pipeline and the liquid storage part form the heat exchanging medium circulating loop, the temperature of the batteries is regulated by the heat exchanging between the heat exchanging part and the batteries so as to guarantee that the heat of the batteries can reach the optimal state at the same time, and heat balance of the multiple batteries can be achieved favorably; the device can store a certain quantity of heat exchanging medium to guarantee that the heat exchanging medium circulating loop has sufficient heat exchanging medium for heat exchanging, and accordingly the normal work of the temperature regulating device cannot be affected by the reduction of the heat exchanging medium.

Description

technical field [0001] The invention relates to the technical field related to batteries, in particular to a temperature regulating device. Background technique [0002] As the energy storage device of electric vehicles, the performance of the battery will have a great impact on the overall performance of the vehicle. Too high or too low temperature will affect the performance of the battery. When the battery is in use, it will generate a lot of heat, and high temperature will have a great impact on the performance of the battery. Therefore, a cooling device is needed to adjust its temperature to ensure its normal operation. . And when the ambient temperature is too low, it will also affect the normal use of the battery. At this time, the battery needs to be heated to keep it at a normal operating temperature to ensure that it can work normally. [0003] Most of the existing electric vehicles are equipped with devices that can adjust the battery temperature, but most of th...

Problems solved by technology

[0003] Most of the existing electric vehicles are equipped with devices that can adjust the battery temperature, but most of them are adjusted by air cooling. This method cannot guarantee the uniformity of heat regulation, and cannot ensure that the temperature of each battery is at the optimum temperature. temperature, so that the performance of all batteries cannot be optimal
