The system is based on aerodynamic power generation devices. The STM32 is the control cove. A power management system suitable for heavy-duty trains is designed to solve the problem that heavy-duty trains cannot achieve electronically controlled air braking. Among them, the power management system detects the battery voltage current and temperature, and can accurately estimate the battery's remaining power through the Kalman filtering algorithm. The pneumatic power generation system in this paper is the basis of the electronically controlled air brake for heavy-duty trains, which provides the conditions for the future research on electronically controlled air brakes.
