摘要
研制了一种用于电动汽车充电桩的直流电能表,介绍了该表计的性能参数、工作原理,并对其软硬件电路进行了设计;测试了采用新型电子式电流互感器和采用分流器在不同负载下的误差数据及功率损耗。从实验结果和市场的分析调查可以看出:该直流电能表的准确度优于传统的直流电能表,并且具有较好的经济性和应用前景。
A DC electricity meter using for electric vehicle charging pile is developed in this paper. The performance parameters and working principle of the meter are introduced,and the software and hardware circuits of the meter are designed. The error data and the power loss using new electronic current transformer and diverter under different loads are tested. The experimental results and social survey analysis conclude that the accuracy of the DC electricity meter is superior to the traditional DC electricity meter. Meanwhile,it has a good economic prospect.
