Hardware Design and Experimental Validation of Thermal Management System for Power Batteries in Electric Vehicles

This article outlines the general concept for the thermal management system of the power battery and the temperature sensor’s hardware selections, primary controller, motor (fan), and other parts depending on their specifications; The primary DSP56F8346 chip was used in the hardware circuit design to create the minimum system and peripheral circuit modules. The temperature acquisition module, signal amplification module, and power drive module designs were also completed, and finally the circuit schematic diagram was created, allowing for the creation of circuit boards. In the lab, tests on the acquisition of temperature signals, speed signals, PWM drive signal output, and other factors were done.
