中文摘要:

采用宽量程计量芯片设计了量程为1(50)A的交流充电桩电能表,该表在20mA～50A的电流范围内,交流有功电能的计量误差优于±0.2%,具备抗直流分量和偶次谐波能力,满足标准对3～21次谐波影响量要求。经检验和现场使用表明,本单相宽量程电能表可以准确计量交流充电桩整个充电过程中的电能。

英文摘要:

AC charging point energy meter with measurement range of 1(50)A has been designed by adopting wide measurement range metering IC.This meter has better than ±0.2% metering error for AC active energy in the current range of 20mA～50A.It has the capability to resist DC component and even harmonic,and it meets the 3 ～ 21 harmonic influence quantity requirement set by standard.Through inspection and field use,it shows that this single phase wide measurement range energy meter can accurately measure the electric energy during the whole charging process of AC charging point.
