中文摘要:
      动力电池的动态性能直接影响电动汽车的起动、加速、续航、快速充电等指标。分析动力电池的测试要求和方法,选择结合实际路况的变功率测试,使用动态应力测试DST(dynamic stress test)标准功率曲线作参考曲线。模拟工况下电池测试设备要求,选用交错并联双向DC/DC变换器为拓扑结构,详尽阐述了变换器的工作原理,给出了参数设计和控制方法。采用TMS320F28335为控制核心,搭建了硬件实验平台进行测试。实验结果表明,所采用的控制方法能实现交错并联双向DC/DC变换器的快速响应,实现能量的双向流动,满足电动汽车动力电池测试的应用要求。
英文摘要:
      The dynamic performance of power batteries directly affects the indicators of electric vehicles(EVs), such as starting, acceleration, mileage and fast charging. In this paper, the test requirements and method for power batteries are analyzed, and the variable power test which is closely combined with actual pavement conditions is selected with the dynamic stress test(DST) standard power curve as a reference curve. In addition, the requirements of battery te-sting equipment are simulated, and an interleaved bidirectional DC/DC converter is selected as the system's topology; moreover, the operation principle of the converter is elaborated, together with the design parameters and control method. TMS320F28335 was adopted as the control center, and a hardware test platform was built. Experiment results indicated that the proposed control method can realize rapid responses from the interleaved parallel bidirectional DC/DC converter, achieving a bidirectional flow of energy and satisfying the application requirements of EV power battery test.
