摘要：

With the shift from the combustion engine to the electric motor, thermal management system is taking on a new significance in the automotive industry. Optimal temperature control of the individual components and air conditioning of the vehicle cabin must be implemented as efficiently as possible to achieve a high driving range and a safe operation of the electric vehicle (EV). With the acceptance of the restriction of PFASs, R744 would be the only, not flammable refrigerant that can be considered for environmentally compatible use in EV heat pumps. A literature review showed the very high potential of R744 heat pump systems for this application. Because of the different properties of R744 compared to the common refrigerants, further investigations are needed to determine suitable system design, operation, and control strategies for R744 heat pump systems in the context of the EVs.
