锂离子动力电池模块循环寿命动态测试方法研究

摘要

Lithium ion power battery is wildly used in electric vehicle for its advantageous performance. Simulating the power consumption in the process of actual service for electric vehicle, this paper employs the dynamic test method to evaluate the cycle life of lithium ion power battery modules. And then the peak power of battery modules in different depth of discharge is investigated. This paper is aimed to provide a dynamic testing method with the domestic related enterprises for reference.%锂离子电池因为其自身性能的优越性而被广泛应用在电动道路车辆中。本文采用动态循环测试方法，模拟电动汽车在实际使用过程中功率的消耗，在此基础上评价锂离子电池模块的循环寿命，并且研究了不同放电深度下电池模块的峰值功率特性。本文旨在提供一种评价锂离子动力电池模块循环寿命的动态测试方法，以供国内相关企业参考使用。
