电动汽车电网适应性测试技术概述

Overview on Electric Vehicle Grid Adaptability Testing Technology

电动汽车的保有量迅速提升,因电网异常导致的充电问题随之出现,电动汽车电网适应性测试是行业内急需应用的热点技术。电网适应性测试技术可应用于整车充电系统或交流充电桩、直流充电桩、车载充电机以及高集成度充电总成,提升充电生态产品的开发质量。为深度适应用户不同场景的充电需求,汽车行业需要全面分析全球电网制式差异,梳理异常电网原理,在电网制式、电网跌落、电网陡升以及电网谐波方面开发覆盖用户充电工况的测试方案,电动汽车充电产品面向市场前被充分验证,规避潜在的电网异常相关的充电问题。

The ownership of electric vehicle(EV)is rapidly increasing,and charging issues caused by grid abnormal power are consequently emerging.EV adaptability testing has become a hot technology urgently needed in the industry.Grid adaptability testing technology can be applied to vehicle charging systems or AC charging piles,DC charging piles,in vehicle chargers,and high integration charging assemblies to improve the development quality of charging ecological products.To deeply adapt to the demands for charging of users in different scenarios,the automotive industry needs to comprehensively analyze the differences in global power grid systems,sort out the principles of abnormal power grids,and develop testing plans covering user charging conditions in terms of power grid systems,power grid drop,power grid steep rise,and power grid harmonics.Electric vehicle charging products should be fully validated before launch to avoid potential abnormal charging problems about the power grid.
