电动汽车智能充电桩的设计与研究

针对当前电动汽车续航能力严重不足以及不能及时充电的问题,将电力电子变流技术、智能监控技术、REIP无线射频技术以及CAN总线技术应用到电动汽车智能充电桩的设计与研究中。开展了无人值守的智能电动车充电桩的现实依据和理论可行性分析,提出了一种兼备CAN总线网络通讯功能和无人值守功能的电动汽车智能充电桩的软件设计方法和硬件结构组成方案,把每个电动汽车智能充电桩视为一个智能节点,建立了上位机组态监控和下位机数据采集相互结合的系统整体框架。在组态软件MCGS上对电动汽车智能充电桩的人机交互界面进行了模拟演示试验,并对电池充电过程中的各项参数指标进行了采集与分析。研究结果表明:电动汽车智能充电桩能够快速地为电动汽车充电,并且具备完善的远程通信和监控功能,保证了电动汽车的续航能力。

Research and design of electric car intelligent charging pile

Aiming at the shortage of the electric car battery life and is not be charged in time,the power electronic converter technology,intelligent monitoring technology,REIP radio frequency technology and CAN bus technology were applied to electric vehicle intelligent charging pile design and research.The unattended intelligent electric vehicle charging pile realistic basis and theoretical feasibility analysis was carried out.The electric car intelligent charging pile design method of software and hardware structure were come up with CAN bus network communication function and unattended function of the,each electric vehicle intelligent charging pile as an intelligent node,established the upper unit machine state monitoring and data acquisition system as a whole framework of combination.On the configuration software MCGS manmachine interface of the electric car intelligent charging pile was simulated demonstration experiment,and the various parameters of the battery in the process of the collection and analysis.The results indicate that the electric car intelligent charging pile can be quickly for electric vehicle charging,and have perfect remote communication and monitoring function,to ensure the electric car battery life.
