Research on Performance Optimal Control of New Energy Vehicle Cooling System

The application and popularization of new energy vehicles have become the strategic trend of the development of China's automobile industry. The cooling system of new energy vehicles is used to maintain the temperature of the vehicle system in a reasonable range to prevent the high temperature from affecting the life of the vehicle or causing faults and accidents. This paper introduces the present situation of the cooling system of new energy vehicles, studies the calculation model of battery cooling, and optimizes and simulates the liquid cooling structure of power lithium battery pack, which verifies the calculation model well and accumulates a lot of practical data.
