Comprehensive Analysis of Battery Thermal Management Systems for New Energy Vehicles

Abstract

In recent years, challenges such as energy scarcity and environmental pollution have become more serious, presenting tremendous prospects for creating new energy vehicles and enabling new energy vehicles to develop swiftly. However, the service life of the power battery of new energy vehicles, the battery capacity is too small and the charging time is extended, etc. have become the bottleneck restricting the development of new energy vehicles, and an effective battery thermal management system is a necessary way to solve these problems. This article describes and evaluates the state-of-arts battery thermal management system plan for new energy cars and introduces the working concept of air, liquid, and phase change cooling systems. This study can assist readers in forming a more thorough knowledge of the evolution of battery thermal management technology for new energy vehicles and give researchers suggestions for thinking about crucial technologies.
