Description

一种电动汽车V2X的能量转换***
技术领域
本发明属于能量转换***技术领域，更为具体地讲，涉及一种电动汽车V2X的能量转换***。
背景技术
随着全球经济的不断发展，人们的物质生活条件的提高，也越来越注重到空气的环保问题，其中燃油汽车的尾气排放一直是空气污染的一个主要污染源之一，所以世界上各个国家都相继出台了电动汽车替代传统的燃油汽车的战略。
以中国为例，2017年中国的电动汽车销量为57.9万辆，占到了世界电动汽车销量的21％。不过电动汽车要真正地替换掉燃油汽车还有很长一段路要走，主要的问题有电动汽车所携带的电量太少，最大行驶路程太小；电动汽车充电问题一直是一个令人头痛的问题。现在主要的充电方式有电动汽车充电站充电，更换电动汽车电池，电动汽车充电站建设的成本大，利用率也不是太理想，寻找充电站困难，占用城市宝贵土地资源等一些问题一直是制约着电动汽车发展的瓶颈。
因此一种将电动汽车的充电器集成在电动汽车里面，给每个电动汽车配备一个专用的适配器，只要在有市电的地方就可以充电是一种新的解决途径。利用电动汽车电池对电量的存储作用对家庭可以发展V2G技术和V2H技术。
另外，V2G技术与V2H技术是同样的原理，都是将电动汽车的直流电源经过逆变成标准的市电然后并网或者供给家庭使用，如果使用双向的逆变模块将电动汽车充电器与V2G和V2H三个技术经过改进有效地结合在一块，从而可以减小成本的投入。
再者，利用电动汽车电池对电量的存储作用，为国家电网的电网调控***智能地调度在网的电动汽车的充电与并网，可以对电网起到削峰填谷的作用，可以减少国家电网额外对修建储能电站的投入。

所述的V2X的能量转换***工作为电动汽车的充电模式时，模式转换器为充电模式，电网接口输入交流电经过能量转换模块转换为适合的直流电对电动汽车进行充电；

所述的模式转换器工作在供电模式时可以电动汽车并网与供给用电器同时进行，电动车并网受电网调控***通过云端调度电池管理***控制，工作在供电模式时只要没有达到电动车电池供电安全阈值的情况下可以一直供给输出。
在一较佳的实例中：所述的云端主要用来传输电网调度***对电池管理***的调度命令和电池管理***反馈的电动汽车电池的实时信息，并可以在线存储电池管理***反馈的电动汽车电池的实时信息。
在一较佳的实例中：所述的电池管理***为中央控制单元，其作为电动汽车与电网调控***的控制桥梁，用来接收电网调控***的命令和发出控制能量转换模块转换成满足电动汽车充电、供给用电器和并网时要求的电源的命令，收集电动汽车电池实时信息，上传到云端。
在一较佳的实例中：所述的能量转换模块包括：LC滤波器、双向逆变器和双向直流斩波器，用于模式转换器工作在充电模式或并网模式时转换成适合的电源进行充电、并网或者供给用电器。
