BMS是电池储能系统的核心子系统之一,负责监控电池储能单元内各电池运行状态,保障储能单元安全可靠运行。BMS能够实时监控、采集储能电池的状态参数,并对相关状态参数进行必要的分析计算,得到更多的系统状态评估参数,并根据特定保护控制策略实现对储能电池本体的有效管控,保证整个电池储能单元的安全可靠运行。


电动汽车的BMS系统较为复杂,实现功能要求更多,如对电动汽车的动力电池参数进行实时监控、故障诊断、SOC估算、行驶里程估算、短路保护、漏电监测、显示报警,充放电模式选择等,并通过CAN总线的方式与车辆集成控制器或充电机进行信息交互,保障电动汽车高效、可靠、安全运行。


BMS单元电路的保护应用

一般BMS包含控制单元、数据采集单元、均衡单元、通讯单元和显示单元等。


1、主控制单元BMU的电源输入保护


电源输入一般选用功率较大TVS,常用型号如下表格:

2、从控制单元BCU的保护应用


由于各家BMS厂商的方案技术有所不同,BCU单元包含有数据采集单元和均衡单元,数据采集单元和均衡单元一般和动力电池连接。一般在其AFE电路的供电处都有放置一个TVS管,一般选取SMB/SMC封装,峰值功率为600W/1500W,并且前面串连有限流电阻。TVS管的电压值根据供电电压选择。


3、充放电回路中MOS管的保护应用


BMS充放电回路中MOS管开关瞬间电流的突变会产生漏极尖峰电压导致MOS管损坏,功率管开关速度越快,产生的过电压也就越高。为了防止MOS管损坏,会在GS间增加大功率的TVS管,选型根据电池的最高电压和 MOS 的耐压来选择,如下表格:

4、通讯单元的保护应用


通讯单元其端口保护器件应用如下表格:

基于硕凯TVS SMBJ24CA的车载LED电源静电整改案例分析

本文介绍车载LED电源静电整改分析。对于弱电产品有金属外壳的产品最好是把外壳接到PCB的工作地,或者PCB有大地的外壳接到PCB的大地。对于主IC不能承受很大的工作电压时选用TVS尽量选用钳位电压低的,比如SMBJ24CA。
