充电桩群控操作管理单元的设计与实现

利用两个充电桩同时对一辆电动汽车充电的技术,设计了充电桩群控操作管理单元对多个充电桩控制管理,既可对小功率的车单充,又可对大功率的车双充。结合"互联网+"技术提出了手机APP、在线卡和离线卡三种支付方式兼容的充电方法。在软件实现上采用模块化设计,规范充电流程,数据流通过消息总线机制在各模块间传输。在双充操作上,充电桩群中任意两个充电桩都可以组合,组合后在其中任一充电桩上可以启动和终止充电,将充电中双桩设置主桩和辅桩进行管理。通过厦门多个公交站的运营情况表明,该充电桩群控操作管理单元使用是稳定可靠的。与传统的充电装置相比,使用充电桩群控操作管理单元使充电功率选择更多元化,充电站设计成本更低。

Design and implementation of charging pile group operation management unit

By using the technology for charging an electric vehicle at the same time with two charging piles, a charging pile group operation management unit is designed to control and manage multiple charging piles, which can be used for both small power single charging electric vehicle and high power double charging electric vehicle. Combined with the "Internet plus" technology, it puts forward mobile phone APP, online and offline card charging method, the three modes of payment is used at the same time. In software, modular design is used to standardize charging process, and data stream is transmitted between modules through message bus mechanism; in the double charging operation, any two of the charging piles can be combined in charging pile group, charging can be started and terminated on any pile after the combination, and the main piles and auxiliary piles are installed in the charging of double piles for management. The operation of a number of Xiamen bus station shows that the charging pile group operation management unit is stable and reliable. Compared with the traditional charging device, charging pile group operation management unit makes the charging power choices more diversified and lowers cost for the charging station design.
