Description

多路输出协调控制电动汽车一体化充电机监控系统及方法
本申请要求于2013年9月17日提交中国专利局、申请号为201310425890.6、发明名称为“多路输出协调控制电动汽车一体化充电机监控系统及方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及汽车充电技术领域，尤其涉及一种多路输出协调控制电动汽车一体化充电机监控系统及方法。
背景技术
随着能源需求和资源环境对人类的挑战，电动汽车数量随之不断增加，与之配套的充电基础设备数量也不断的增长，其充电问题对人员安全及电网影响越来越受到重视，因此，安全可靠的电动汽车充电机的监控系统会起到重要的作用。
现有的电动汽车充电机的监控系统往往停留在常规采集和基本控制上，没有分工作状态来考虑监控策略，而且，没有一个最优策略的选择，面对充电过程中遇到的问题，没有灵活、合理的充电方案和保护方案，致使电动汽车充电站的监控领域存在很大的安全隐患。
在国家知识产权局于2013年1月公布的中国专利(授权公告号CN202678987U，名称为“电动汽车充电机的监控装置”)，和国家知识产权局于2011年1月5号公告的中国专利(授权公告号CN201699445U，名称为“一种用于电动汽车充电站的充电机监控装置”)，和国家知识产权局于2012年12月26号公告的中国专利(授权公告号CN202632088U，名称为“基于云计算平台的电动汽车充电机监控装置”)的专利中都提出了电动汽车充电机监控方面的方案。经过分析，所公布的现有电动汽车充电机监控存在以下技术问题：
1现有技术中，尚没有考虑到将多路输出协调控制电动汽车的充电机和充电桩一体化，更没有涉及到一体化充电机的监控系统及监控方法，而且现有的监控系统仅仅能采集充电机的一个功率输出口的数据，并不能采集充电机的多个功率输出口的数据，更没有提出如何对多路功率输出口的数据进行处理；
2所提到的充电机的充电输出没有多路输出功能。当多辆电动汽车同时需 求充电时，充电机没有提供多个功率输出接口，对于充电装置量少的站点，需要等待很长时间，造成电动汽车调度时间长，充电机效率利用率低等问题；
3所提到的充电方案的策略定制功能薄弱。对充电机工作中的出现的因素，缺少明确的工作状态划分，对不同工作状态下出现的各种因素，仅仅停留在常规的采集和基本的控制层面，缺少综合评估分析，更没有及时提供针对评估分析结果做出最优的充电策略及保护策略，而是往往对问题处理不及时不准确，造成误判断、误报警，重复操作，隐性增加人员排查问题工作量。
