With the development of the electric vehicle industry

the application scope of fast charging and high-power power systems for electric vehicle batteries is becoming increasingly wide. The phenomena of heat accumulation

uneven temperature distribution

and local thermal runaway during battery operation are also increasing

which can easily cause electric vehicle safety accidents. Based on the above issues

the research systematically summarizes the development trend of liquid cooling and heat dissipation technology for electric vehicles

and summarizes the comprehensive application of thermal energy analysis technology and liquid energy heat dissipation technology for electric vehicles. This objectively demonstrates the practical application value of thermal energy analysis technology in battery liquid cooling heat dissipation and battery thermal management

which can provide certain ideas and references for the development of battery thermal management systems in automotive enterprises.
