Research status of liquid cooling technology for lithium ion batteries
In order to maximize the efficiency of lithium-ion battery,it is necessary to design a reasonable battery thermal management scheme for the current temperature rise and temperature uniformity of electric vehicle batteries.Firstly,compared with air cooling,liquid cooling has gradually become the mainstream cooling method due to its irreplaceable advantages in the practical application of lithium ion battery thermal management scheme.Secondly,from the four angles of structure design,cooling medium,direct cooling and liquid cooling-PCM composite cooling,the research status of liquid cooling mode is summarized,and the respective cooling characteristics and comparisons of various parameters are summarized,which provides a reference for the model design and structural parameters of liquid cooling in the future.Finally,the measures taken in the follow-up study are proposed for the lack of liquid cooling.
