Abstract

The battery management system (BMS) measures cells voltage, temperature and battery current, acting as security controller, monitoring and reporting the state of the battery and also balancing it. It must be accurately validated and tested before to use. The HiL test is the better solution to test it in order to develop algorithms in a fast way, to test the BMS board using a secure and reproducible way, and to simulate extreme condition of lithium cells. This work introduces the HiL test system defining its specifications. The challenge of HiL test on BMS is to replicate the behaviour of the lithium cells without using them. For this purpose, a battery cell emulator board is proposed and analysed. Some SPICE simulations were conducted at design stage and the result were compared with the defined specifications. The battery cell emulator, being isolated from the main power supply, can be used in series connection simulating higher voltage batteries in the HiL test of BMSs.

用于硬件在环BMS测试的电池模拟器

电池管理系统(BMS)测量电池电压、温度和电池电流，作为安全控制器，监测和报告电池的状态，并进行平衡。在使用前必须经过准确的验证和测试。为了快速开发算法，使用安全和可重复的方式测试BMS板，并模拟锂电池的极端条件，HiL测试是测试它的更好解决方案。本文介绍了HiL测试系统，并定义了测试系统的技术指标。在BMS上进行HiL测试的挑战是在不使用锂电池的情况下复制锂电池的行为。为此，提出并分析了一种电池仿真板。在设计阶段进行了SPICE仿真，并将仿真结果与设计规范进行了比较。电池仿真器与主电源隔离，可在bms的HiL试验中串联模拟高压电池。
