新能源汽车电池散热风扇驱动系统设计

Driving system design of the battery cooling fan of new energy vehicle

采用基于Contex-M3架构的STM32系列单片机作为主控芯片,在uvision4环境中以C语言设计驱动系统软件;通过设计制作的系统硬件电路板,在新能源汽车电池散热风扇上进行空载试验,测试驱动系统对散热风扇的控制效果,并比较求反正切和锁相环2种转子位置信息估算方法的差异性.

Using STM32 series single chip microcomputer based on Contex-M3 architecture as main control chip, drive system software was designed by using C language in uvision4 environment. The no-load tests were made through the design of the system hardware circuit board to test the performance of driver system, and the difference of two rotor position estimating methods was analyzed and compared in software and hardware.
