一种基于虚负荷测试非车载充电机电能计量性能的系统和方法
摘要：
本发明涉及一种基于虚负荷测试非车载充电机电能计量性能的系统和方法，所述系统包括：直流电压源1，其用于向非车载充电机3输出直流电压信号；直流电流源2，其用于向非车载充电机3输出直流电流信号；非车载充电机3，其具有虚负荷测试部分，所述虚负荷测试部分的计量模块用于计量经过非车载充电机3的电能；直流电能表4，其用于计量经过非车载充电机3的电能，将直流电能表4计量的电能与非车载充电机3的计量模块计量的电能进行比较，得到的电能差值即为非车载充电机的电能计量误差。
摘要（英）：

The invention relates to a non-vehicle charger electric energy metering performance test system and method based on a virtual load. The system comprises a DC voltage source 1, a DC current source 2, a non-vehicle charger 3 and a DC electric meter 4, wherein the DC voltage source is used for outputting a DC voltage signal to the non-vehicle charger 3, the DC current source is used for outputting a DC current signal to the non-vehicle charger 3, the non-vehicle charger has a virtual load test portion, a metering module of the virtual load test portion is used for metering electric energy passing through the non-vehicle charger 3, the DC electric meter is used for metering the electric energy passing through the non-vehicle charger 3, the electric energy metered by the DC electric meter is compared with the electric energy metered by the metering module of the non-vehicle charger 3 to acquire electric energy difference, and the electric energy difference is an electric energy metering error of the non-vehicle charger.
