基于电动汽车充电系统的几点分析

随着《新能源汽车产业发展规划(2021-2035年)》等相关文件的出台,进一步表明国家对加速发展电动汽车这一行业的决心,充电系统是电动汽车核心技术之一,它能够把外部的电能通过化学反应的方式储存在电池内部,以备车辆使用,而往往充电时间主要取决于充电机功率的大小,功率越大充电时间越短反之俞长。本文主要以比亚迪E5车型为对象,分别从充电系统的构成、充电枪电子锁、慢充控制策略、充电失效几个方面进行简要阐述分析,以供学习参考使用。

Analysis based on Electric Vehicle Charging System

The publication of the"New Energy Vehicle Industry Development Plan(2021-2035)"and other related documents,demonstrates China’s determination to accelerate the development of the electric vehicle industry.The charging system is one of the core technologies of electric vehicles.The external electric energy is stored in the battery through a chemical reaction to prepare for the use of the vehicle,and often the charging time mainly depends on the power of the charger.The greater the power,the shorter the charging time,and vice versa.This article mainly focuses on the BYD E5 model,and briefl y analyzes the composition of the charging system,the electronic lock of the charging gun,the slow charging control strategy,and the charging failure for reference.
