Simulation of Electric Vehicle Air Conditioning System and Optimization of Algorithm

Through establishing the EV air conditioning system model, a more energy saving control algorithm is developed. This article built electric air conditioning system compressor model, compartment thermal load model, heat transfer model, controller model and temperature calculation model based on certain pure electric commercial vehicle air conditioning system. A compound control method applying fuzzy and PID theory is put forward in this paper. At the same time the paper established a secondary development of EV model in ADVISOR. As the result shows, the fuzzy-PID control method is more accuracy and consuming less energy. Optimized control algorithm for air condition is realized.
