由于我们运输方式的改变和繁荣程度的提高，运输部门的巨大增长直接反映在能源需求的加剧上。因此，已经生产了电动车辆（EV）以最小化传统车辆的能量消耗。虽然电动汽车发动机比内燃机更有效，但在确定整体能源效率方面，应研究井到轮（WTW）效率。简而言之，这项研究将试图回答一个基本问题-电动汽车与ICE动力汽车相比真的节能吗？本研究调查传统内燃机车辆ICEV（汽油，柴油），压缩天然气汽车（CNGV）和电动汽车的WTW效率。结果表明，电厂效率对WTW效率有显着的后果。汽油ICEV的总WTW效率范围在11- 27%之间，柴油ICEV范围在25%-37%之间，并且CNGV范围在12%-22%之间。由天然气发电厂供给的EV显示出最高的WTW效率，其范围在13%-31%之间。而燃煤和柴油发电厂提供的电动汽车具有大致相同的WTW效率，分别为13%至27%和12%至25%。如果使用可再生能源，损失将显著下降，电动汽车的总体效率将在40- 70%左右，具体取决于可再生能源系统的来源和位置。
The tremendous growth in the transportation sector as a result of changes in our ways of transport and a rise in the level of prosperity was reflected directly by the intensification of energy needs. Thus, electric vehicles (EV) have been produced to minimise the energy consumption of conventional vehicles. Although the EV motor is more efficient than the internal combustion engine, the well to wheel (WTW) efficiency should be investigated in terms of determining the overall energy efficiency. In simple words, this study will try to answer the basic question - is the electric car really energy efficient compared with ICE-powered vehicles? This study investigates the WTW efficiency of conventional internal combustion engine vehicles ICEVs (gasoline, diesel), compressed natural gas vehicles (CNGV) and EVs. The results show that power plant efficiency has a significant consequence on WTW efficiency. The total WTW efficiency of gasoline ICEV ranges between 11-27 %, diesel ICEV ranges from 25 % to 37 % and CNGV ranges from 12 % to 22 % The EV fed by a natural gas power plant shows the highest WTW efficiency which ranges from 13 % to 31 %. While the EV supplied by coal-fired and diesel power plants have approximately the same WTW efficiency ranging between 13 % to 27 % and 12 % to 25 %, respectively. If renewable energy is used, the losses will drop significantly and the overall efficiency for electric cars will be around 40-70 % depending on the source and the location of the renewable energy systems.
