Abstract
Abstract The problem of “range anxiety” of electric vehicles is gradually highlighted. Especially when the onboard air conditioner is used by electric vehicles in winter, its actual range will be significantly shortened. This paper comprehensively analyzes the impact of fresh air demand on the energy consumption of the PTC(Positive Temperature Coefficient)heating system, so that the intelligent control strategy of fresh air under heating conditions is proposed, and the energy-saving effect of the intelligent control scheme is analyzed. It is found that the intelligent control strategy of fresh air can significantly reduce the energy consumption of the system. At the same time, a certain electric vehicle with a battery energy of 100kW·h was selected to analyze its range. It is found that the range of the intelligent control scheme is increased by about 32.34% when the ambient temperature is 0°C.
