In the present study, an integrated electric vehicle thermal management system (EVTMS) for cabin thermal comfort, battery cooling and motor waste heat recovery was proposed. The effects of parameters such as compressor speed, environmental temperature and waste heat load on EVTMS cooling and heating performance were investigated. The results demonstrated that the percentage of cooling capacity reduction (PCCR) was in the range of 26.30-32.10% and the percentage of waste heat recovery (PWHR) was in the range of 18.73-45.17%. In addition, EVTMS model was developed and validated with experimental data, which predicted energy consumption, system capacity and COP with MRE in the range of 0.68-21.05%. Hybrid simulation method was carried out to study the effect of EVTMS on vehicles driving range. Meanwhile, dynamic characteristics of battery temperature, motor temperature and battery State of Charge (SOC) were investigated. The results showed that SOC was reduced up to 10.60% with battery cooling and heating COP was increased up to 25.55% with motor waste heat recovery. Compared to PTC heaters, vehicles driving range with EVTMS was improved 31.71%.
