Study On Critical Accessory Components Of Hybrid Electric Vehicle

Nowadays, green, low carbon and environment protection are the theme of thetimes. Traditional fuel vehicles are replaced by new energy vehicles. Those newenergies include new type fuel, fuel gases (nature gas and liquefied gas), biomass fueland hybrid power(pure electric and fuel battery). Considering exhaust emission,energy utilization ratio and economy, hybrid power vehicles have a promising future.At present, the researches about hybrid power vehicles focus on battery and motor,thus the key auxiliary components get less attention. This paper aims at improving theeconomy by the means of studying the key auxiliary components, so that the energyutilization ratio is higher.The structure, technologies and application that this paper has mentioned can beused in other type vehicles. In the beginning, the necessity of developing hybridpower vehicles and key auxiliary components. Then, the hybrid power vehicle modeldesigned by this paper is introduced by discussing the control strategy of the keyauxiliary components. This paper choose air conditioning compressor as study object.The simulation of vehicle power system and air conditioning compressor has beendone to analyze the control strategies. By using simulation method, this paper provesthat the control strategies have really worked and the energy utilization ratio isimproved by adjust the air conditioning compressor.
