随着新能源的日渐紧缺和环境污染的愈加严峻，电动汽车以其优越的环保和节能特性，成为了汽车工业研究和开发的热点。电动汽车的一个重要动力组成部分是充电模块，其技术水平的高低对电动汽车产业的发展有着极其重要的影响。With the increasing shortage of new energy sources and the increasingly severe environmental pollution, electric vehicles have become a hot spot in the research and development of the automotive industry due to their superior environmental protection and energy-saving characteristics. An important driving component of electric vehicles is the charging module, whose technical level has an extremely important impact on the development of the electric vehicle industry.
现有技术中，电动汽车的充电连接方式主要有两种，一种为充电桩直流充电方式，一种为车载充电机交流充电模式，电动汽车为了解决充电问题，一般都会支持这两种充电连接方式，目前，充电桩只能上报直流充电时的状态，车载充电机只能上报交流充电时的状态，不利于充电状态的监测。In the prior art, there are mainly two charging connection modes of an electric vehicle, one is a charging charging mode of the charging pile, and the other is an alternating charging mode of the electric vehicle charging device.
