Analysis and Optimization of the Thermal Management System for the Pure Electric Vehicle Battery Packs

Under high load conditions the battery packs of the pure electric vehicle will have a high heat production rate with high-current discharge, causing the rapidly increasing temperature of the battery, and resulting in a reduction of the battery cycle life and vehicle endurance mileage. In order to solve the problem, the paper used computer-aided analysis and simulated the temperature distribution of the electric vehicle battery pack for urban road conditions and high temperature conditions. Comparing the maximum temperature of the battery pack with or without using the thermal management system, such a conclusion was obtained that with the optimized thermal management system, the battery pack can work in a better environment and the battery cycle life and endurance mileage can be improved.
