Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a liquid cooling plate for a power battery of an electric vehicle. Background technique [0002] With the development of social economy and the further increase of energy demand, the voice of new energy technology is getting higher and higher, and the development of electric vehicles has become the general trend. As the core part of electric vehicles, battery performance and service life directly determine the performance and cost of electric vehicles. [0003] Due to the advantages of long life, low self-discharge rate, high specific power, high energy density and no pollution, lithium-ion power batteries have become the main power batteries used in electric vehicles. However, there is a problem with the optimal temperature range for lithium-ion battery discharge. When the battery temperature is too high or too low, exceeding its allowable operating temperature range,...
