Abstract

The invention relates to a power battery temperature adjusting device used for adjusting the temperatures of a plurality of battery cells of a power battery pack by means of a temperature adjusting medium. The power battery temperature adjusting device comprises an inlet collecting tube, an outlet collecting tube, a plurality of heat exchange plates which are parallelly communicated between the inlet collecting tube and the outlet collecting tube to make each of the battery cells adjacent to at least one of the heat exchange plates respectively, and a shell used for accommodating all the battery cells of the power battery pack and the heat exchange plates. The invention also relates to a making method of the power battery temperature adjusting device.

Description

technical field [0001] The invention relates to a power battery temperature regulating device for regulating the temperature of a plurality of battery cells of a power battery pack and a manufacturing method of the power battery temperature regulating device. Background technique [0002] Lithium batteries are currently a key component of electric vehicles and hybrid vehicles, providing drive power and / or energy supply for other functions. However, the lithium battery is greatly affected by the ambient temperature or its own temperature. If the temperature is too high or too low, its performance will be significantly reduced and its charge and discharge times will be reduced. At the same time, in practical applications, multiple battery cells are often integrated into a lithium power battery pack to provide higher power. Here, it is necessary to ensure the temperature uniformity of each battery cell in the lithium power battery pack, and the temperature difference of each b...
