Abstract

Lithium-ion (Li-ion) battery has played a key role for the development of electric vehicle (EV) at present, while the Li-ion batteries in the market come from different manufactures. Verifying the performance of the battery management system (BMS) for various battery chemistries is a complex undertaking. This paper proposes a high-fidelity Li-ion battery emulator for EV applications. The emulator utilizes a battery model parameterized by a series of performance tests and a special-designed hardware platform. A three-order battery equivalent circuit model (ECM) is selected to provide the voltage and current reference signal in the processor. Subsequently, the hardware generates the high voltage and current signal in accordance with the reference. To ensure the high accuracy of the battery ECM, a 37 Ah nickel manganese cobalt (NMC) battery was selected for testing under both charge and discharge conditions, as well as across a temperature range of - 30℃ to 45℃. The battery emulator is verified on charge and discharge mode for both accuracy and dynamic performance validations.

摘要

锂离子（Li-ion）电池目前在电动汽车（EV）的发展中发挥了关键作用，而市场上的锂离子电池来自不同制造商。验证针对各种电池化学组成的电池管理系统（BMS）的性能是一项复杂的工作。本文提出了一种用于电动汽车应用的高保真锂离子电池模拟器。该模拟器利用通过一系列性能测试参数化的电池模型和一个特殊设计的硬件平台。选择一个三阶电池等效电路模型（ECM）在处理器中提供电压和电流参考信号。随后，硬件根据该参考生成高电压和电流信号。为确保电池ECM的高精度，选择了一个37 Ah的镍锰钴（NMC）电池在充电和放电条件下以及在-30℃至45℃的温度范围内进行测试。对电池模拟器在充电和放电模式下进行了验证，以进行精度和动态性能验证。
