摘要

In order to save the battery energy consumption of HEV (hybrid electric vehicle), this study designs a novel structure of the AC (air-conditioning system) considering the switching of driving modes of HEVs from the perspective of compressor control of the AC. The main research contents are as follows: firstly, an ordinary AC model is established and compared with experimental data for verification; secondly, a HAC (hybrid air-conditioning system) scheme is designed on this basis, including the hybrid AC structure in which the compressor power source is either the engine or the electric motor, and the compressor control strategy that is tightly coupled with the switching of the driving mode of the HEV; finally, a reference comparison of the electric motor-driven compressor is set up. The results showed that the \(T_{{{\text{cab}}}}\) T cab (passenger compartment temperature) is reduced from an initial temperature of 40 °C to 22 °C within 53 s, satisfying the \(T_{{{\text{cab}}}}\) T cab requirement. Under one NEDC (New European Driving Cycle), the energy consumption of the hybrid drive system designed in this study is reduced by 1.03% compared with the final value of the high-voltage battery SOC (state of charge) when driven by the pure electric motor, which represents a significant energy saving effect.
