新能源车LV123法规测试的好帮手 - Chroma高压直流电源测试软件
2017/12/25

整合各界车厂在新能源汽车的法规需求,提供使用者专业且便利的测试方案,做为新能源汽车测试的好伙伴。

LV123是由欧系各大车厂编订于新能源汽车的电气特性测试及安全规范,针对其高压系统零件,如高压电池系统 (HV battery system)、逆变器 (Inverter)、电气空调压缩机 (Electrical air conditioning compressor)、电力传输油压泵 (Electrical transmission oil pump)、DC/DC高低压转换器 (DC/DC converter HV/LV)、车载充电器 (On-board charger)等,对其电压范围的操作性能,定义其状态的标准。

Chroma直流电源产品62150H-1000支持0-1000V的电压输出,且可达40V/ms的电压斜率控制,充分满足LV123基本电气特性所需,如下列项目,提供最佳新能源车电气测试方案。

Overvoltage at load dump V pk 220 410 500 800
Upper HV circuit limit voltage V pk 220 410 500 800
Maximum operating voltage V d.c. 200 360 470 770
Upper limited operating capability V d.c. > 190 - 220 > 340 - 460 > 450 - 470 > 750 - 770
Unlimited operating capability V d.c. 90 - 190 170 - 340 250 - 450 520 - 750
Lower limited operating capability V d.c. 80 -< 90 160 -< 170 200 -< 250 450 -< 520
Highly limited operating capability V d.c. 60 -< 80 120 -< 160 200 -< 250 -
Undervoltage V d.c. 0 -< 60 0 -< 120 0 -< 150 0 -< 450

依据LV123规范,提供下列测试项目:

  1. Range of unlimited operating capability
