Aiming at the problem that aviation battery is sensitive to ambient temperature during normal operation, a design scheme of aviation battery temperature controller based on PIC microcontroller and CPLD is designed to meet the requirements of stability and efficiency of aviation battery during operation. The temperature of aviation battery The basic function of the controller is to sample the real-time temperature in the air battery box and realize the power regulation algorithm of the battery temperature by the PIC microcontroller. At the same time, the communication with the avionics equipment is achieved through the ARINC 429 bus so as to achieve the remote monitoring of the battery ambient temperature. It is proved that the controller can effectively solve the problem of sensitivity to the ambient temperature when the aircraft battery is working. At the same time, the controller is stable, efficient, reliable and easy to operate, providing a better platform for subsequent expansion.
