本文阐述以D SP高速处理器T M S320F2812和Z igbee物联网技术相结合的无线充电系统。无线充电系统由一次侧和二次侧两部分组成,一次侧连接电源通过谐振线圈将电能传送到二次侧,二次侧连接电池实现电池充电。为了把二次侧电池的输出电压、输出电流和实时温度的数据反馈给一次侧的控制器,现以T M S320F2812分别作为一次侧和二次的处理器,用支持Z igbee技术的C C 2530芯片作为两侧无线收发模块。电动汽车电池管理系统的温度传感器、电压传感器、电流传感器的信息通过C A N总线收集到二次侧的T M S320F2812处理器,处理器通过I/O接口传到二次的C C 2530芯片,芯片无线R F模块完成数据发送。一次侧C C 2530芯片无线R F模块完成数据接受,一次侧控制器处接收到C C 2530的数据并判断电池充电状态,随后通过PW M来改变一次侧的输入功率实现电池的充电。

This paper describes the DSP high-speed processor TMS320F2812 and zigbee material networking technology combined with the wireless charging system. The wireless charging system consists of the primary and seeondary sides. The primary side connects the power supply to the secondary side through the resonant coil, and the secondary side is connected to the battery. In order to feedback the output voltage, output current and real-time temperature of the seeondary battery to the controller on the primary side, the TMS320F2812 is used as the primary and secondary processors respectively, and the CC2530 chip supporting zigbee technology is used as the wireless transceiver module. Electric vehicle battery management system temperature sensor, voltage sensor, current sensor information through the CAN bus to collect the secondary side of the TMS320F2812 processor, the proeessor through the I/O interface to the secondary CC2530 chip, chip wireless RF module to complete the data send. The primary side CC2530 chip wireless RF module to complete the data to accept the primary side of the controller to receive CC2530 data to determine the battery charge state, followed by PWM to change the primary side of the input power to achieve battery charging. In the system plus the host computer is connected to the battery information in order to display the battery on the host computer for monitoring.
