国内电动汽车和直流充电桩兼容性测试和分析

Test and Analysis on Domestic Electric Vehicles and DC Charging Piles′Charging Compatibility

随着纯电动汽车的普及,充电焦虑成为制约其发展的重要因素。为进一步推动国内电动汽车充电兼容性的发展,试验室制定了电动汽车和充电桩实地测试项目,组织了国内主流品牌的电动汽车在京津冀、上海、深圳等地的充电站进行了充电兼容测试。由于直流充电电流大,危险系数高,本次测试主要围绕直流充电匹配性展开。本文综合各个地区的测试情况,将测试结果汇总,从现场充电环境、充电接口以及绝缘检测处理等方面进行分析,给出国内车桩充电时存在的普遍问题。

With the popularity of electric vehicles, charging anxiety has become an important factor restricting its development. In order to further promote the development of domestic electric vehicles＇ charging compatibility,a field test project has been set up with the laboratory, which organized domestic mainstream electric car makers to participate the charging compatibility test at the charging station of Beijing, Tianjin, Hebei and Shanghai. Owing to the high DC charging current and high risk coefficient, this test was mainly focused on DC charging matching. In this paper, the test results of each area are summarized, problems in the actual charging sites are considered in the field of charging environment, charging interface and insulation detection. At last, general charging problems of electric vehicles in China are given.
