本文利用GREET模型计算了混合动力汽车(HEV)和纯电动汽车(BEV)的能源消费量与CO2排放量,并在此基础上分别模拟了不同电力结构和发电技术路线下的HEV和BEV的减排潜力。结果表明:在2011年的汽车技术条件下,HEV和BEV的节能率分别为24.24%和37.23%,减排率分别为24.24%和19.90%,BEV实现了更好的节能效果,在减排效果上仍不如HEV。由模拟结果得出在汽车技术不变的条件下BEV仍然有减排潜力,当火电比例低于75%或火力发电效率高于37%时,BEV的节能与减排效果均优于HEV,最后根据该结论提出了我国发展HEV和BEV的对策。
In this paper, the GREET model was used to calculate the energy consumption and CO2 emissions of hybrid electric vehicles (HEVs) and pure electric vehicles (BEVs). Based on this, the HEVs and BEVs under different power structure and power generation technologies were subtracted Row potential. The results show that the energy saving rates of HEV and BEV are 24.24% and 37.23%, respectively, and the emission reduction rates are respectively 24.24% and 19.90% under the automobile technical conditions of 2011. BEV achieves better energy-saving effect, Still not as good as HEV. The simulation results show that BEV still has emission reduction potential under the condition of constant automotive technology. When the proportion of thermal power is less than 75% or the thermal power generation efficiency is higher than 37%, BEV is better than HEV in energy saving and emission reduction. Finally, Based on this conclusion, the countermeasures for developing HEV and BEV in our country are put forward.
