摘要：

针对电池管理系统（BMS）测试平台需模拟动力电池输出电压的需求,提出单体动力电池模拟单元的方案.基于伏秒平衡原理对电流和电压纹波的分析,并通过Matlab/Simulink对双向半桥DC-DC电路进行仿真,分析电感值、PWM频率和占空比对电压纹波的影响.对模拟单元进行的输出电压精度测量试验、动态响应时间试验、一致性测量试验,验证了模拟单元的输出电压精度稳定在0.2%以内,动态响应时间在100 ms以内,以及不同模拟单元性能的一致性.结果表明,模拟单元符合实际应用的技术指标,它的研究与实现为电池管理系统测试平台提供了必不可少的测试条件.
Abstract:

 Based on the requirement of output voltage of battery cell in battery management system (BMS) testing platform, we designed the battery cell simulator project. On the strength of analysis of current and voltage ripple with the volt-second balance principle, we simulated the bi-directional half-bridge DC-DC current by Matlab/Simulink and analyzed the influence of inductance, PMW frequency and duty ratio to voltage ripple. Several tests were carried out including output voltage accuracy test, dynamic response time test and system consistency test. The results showed that the precision of output voltage is within 0.2% and dynamic response is kept within 100 ms. Moreover, well consistency was achieved in different cell simulators. The experimental results indicate that the cell simulator conforms to the practical application and the implementation for the simulator provides prerequisites for the BMS test platform.
