基于STM32F103的7kW单相交流充电桩的系统设计与实现

Design and Realization of 7kW Single-phase AC Charging System Based on STM32

随着电动汽车产量的不断增加并逐步取代燃油汽车,与之配套的充电桩却尚未普及,车桩比例严重失衡,成为电动汽车推广的关键制约。因此,加速充电桩的研究和投放,提升充电桩的性能,便成了充电桩发展和研究的重中之重。本文基于STM32F103芯片设计一款带有电能计量、刷卡支付、通信、安全防护等功能的7kW单相交流充电桩,并进行相应的硬件、软件设计。测试结果表明,所设计充电桩各项数据均达到国标要求,能与车辆快速准确响应,可投放于实际充电场景。

With the increasing production of electric vehicles and gradually replace fuel cars,matching charging piles are not yet widely available,and the proportion of car pile is seriously unbalanced,which has become a key constraint for the promotion of electric vehicles.Based on STM32F103 chip,this paper designs a single-phase AC charging pile with power metering,card payment,short circuit protection,adhesion detection and other functions,and carries out the corresponding hardware and software design.The test results show that all the data of the designed charging pile meet the requirements of national standard,can respond quickly and accurately with the vehicle,and can be put into the actual charging scene.
