通过模拟温度变化检测电池管理系统 (BMS)

测试系统在电池模型中产生控制电压，以便模拟电池管理系统的温度条件，并评估 BMS 的温度管理。

主要应用事实

领域

检测电动汽车中的高压组件

应用

模拟温度变化，以检测电池管理系统 (BMS)

测量参数

用于控制功能的 0-10 V 标准信号

主要要求

模拟温度的高质量信号转换，以评估 BMS 性能。

对电池模型和施加了高电压的 BMS 之间的电压进行电气隔离，确保安全。

模拟检测 BMS

应用说明

电动汽车电池的使用寿命在很大程度上取决于电池管理系统 (BMS) 的质量。
在每一个电池电芯中监测充放电电流、电压和温度之类的参数。
确定 BMS 对各个电芯温度变化的反应尤为重要。

将电池电芯放在气候试验箱中，使其处于整个温度范围内来评估 BMS 性能，不仅成本高昂，而且非常耗时。因此，通常选择模拟温度变化。为此，测试系统在电池模型中产生控制电压，以检测 BMS 温度管理。电池仿真使用为 BMS 设计的电池电压。目前电压最高 950 V DC，未来尤其在商用车中将达到 1500 V DC 甚至更高。

应用的要求

适当模拟电池管理系统上的温度条件需要准确性和安全性。
此外，最好能灵活选择输入和输出信号，因为变化的测试场景可能需要调整信号范围或信号类型。灵活性更高，单一解决方案能够适应测试环境内众多可能的信号转换和隔离要求。

为何选择 Knick?
P41000 高压隔离放大器可以将标准控制信号从输入端传输到输出端。输出端与输入端和电源之间为高达 1650 V DC 的电位隔离。响应时间 T90 为 110 μs，截止频率为 5 kHz。校准切换多达 16 个可自由选择的输入/输出范围，灵活性出色。
