摘　　要：针对电动汽车预约充电过程中云端无法实现获取多电动汽车电量以及位置的问题,设计并实现了一种用于电动汽车预约充电的电动汽车状态监控系统。系统主要由主控模块和通信模块以及定位模块构成,其中主控模块使用STM32F429,通信模块使用ATK-M750模组,定位模块为SkyTra_GPS,利用分压模块将电动汽车电池电压对应降低后通过STM32的A/D转换模块获取当前电池电压。系统使用MQTT协议将车辆信息上传到阿里云物联网平台,为电动汽车预约充电配对系统提供了一个可靠数据接口,用以实现电动汽车的充电配对。Aiming at the problem that the cloud can not obtain the electric quantity and position of multiple electric vehicles in the process of EV(electric vehicle)reservation charging,an status monitoring system for EV reservation charging is designed and implemented.The system is mainly composed of the main control module,communication module and positioning module,among which the main control module uses STM32F429,the communication module uses ATK-M750 module,and the positioning module is SkyTra_GPS.The current battery voltage of EV is obtained through the A/D conversion module of STM32 after corresponding reduction of the voltage module.The system uploads the vehicle information to the Ali cloud platform through MQTT protocol,and provides a reliable data interface for the EV reservation charging pairing system to realize EV charging pairing.
