Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a power battery temperature regulating device. Background technique [0002] Due to the temperature characteristics of lithium-ion batteries in automotive power systems, the charging and discharging performance of the battery system is limited or cannot work when the ambient temperature is too high or too low. In the prior art, in order to make the battery system work within its allowable range, the battery system’s own power is used to adjust the temperature of the battery cells in the battery system. The disadvantages of this solution are: using a large amount of battery power to maintain the battery system’s operating temperature, Thereby sacrificing the driving range of the whole vehicle. Contents of the invention [0003] In order to solve the problems in the prior art, an embodiment of the present invention provides a temperature regulating device for a power...
