21、f their powertrains,namely battery electric vehicles(BEVs),plug-in hybrid electric vehicles(PHEVs),hybrid electric vehicles(HEVs),and fuel-cell electric vehicles(FCEVs).Only BEVs and PHEVs are plug-capable,and are referred to as plug-in electric vehicles(PEVs).1.3 Classifications of Electric Vehicle
22、s 电动汽车的分类电动汽车的分类1.3.1 Battery Electric Vehicles1.3.1 Battery Electric Vehicles BEVs also known as pure electric vehicles,full electric vehicles or electric vehicles(EV),are powered by an electric motor and do not employ an internalinternal combustion engine，as shown in Figure 1.5.The battery provide
23、d electric energy to the motor and used as the energy storage unit of a BEV is charged primarily by the power grid and partially via regenerative braking.1.3 Classifications of Electric Vehicles 电动汽车的分类电动汽车的分类Fig.1.5 Drive train schematic diagram of BEV 1.3 Classifications of Electric Vehicles 电动汽车的
24、分类电动汽车的分类 Battery electric vehicles do not have tailpipe emissions;therefore,they are also called zero-emission vehicles.In order to facilitate reasonable driving ranges,the BEVs typically have the largest battery packs compared to other models.The size of these battery packs usually varies between
25、20 kWh to 85 kWh with all-electric-range(AER)of 80 300 miles.Currently,a variety of commercial battery electric vehicles are available in the market.1.3 Classifications of Electric Vehicles 电动汽车的分类电动汽车的分类1.3.2 Hybrid Electric Vehicles1.3.2 Hybrid Electric VehiclesHEVs are primarily powered by intern
26、al combustion engines,which use conventional fuels such as gasoline and diesel.These vehicles are also equipped with battery packs,which are charged by regenerative braking systems and are mainly used to enhance the fuel efficiency of the vehicle.The first generation of HEVs was presented to the mar
27、ket in 1997,when Toyota introduced the Prius model,and two years later Honda introduced the Insight model.As of mid-2015 more than 10 million HEVs were deployed worldwide.1.3 Classifications of Electric Vehicles 电动汽车的分类电动汽车的分类1.3.3 Plug-in Hybrid Electric Vehicles1.3.3 Plug-in Hybrid Electric Vehicl
28、es As shown in Figure 1.6,PHEVs employ both an electric motor and an internal combustion engine(ICE),which can use gasoline or diesel.Typically,PHEV batteries are smaller than those of BEVs,because the required driving range is mostly supported by internal combustion engines and their combined drivi
29、ng range is higher than that of BEVs.As a result,the main advantage of PHEVs is employing both engines types,which helps the consumers overcome range anxiety.In PHEVs,the electric motor is used mostly in urban environments where driving involves frequent stops.On the other hand,an internal combustio
30、n engine is used when the battery is depleted,during intensive cooling or heating,or during rapid acceleration.1.3 Classifications of Electric Vehicles 电动汽车的分类电动汽车的分类Figure 1.6 Drive train schematic diagram of PHEV1.3 Classifications of Electric Vehicles 电动汽车的分类电动汽车的分类1.3.4 Fuel-Cell Electric Vehicl

32、s is more efficient than those in the conventional ICEVs,and they do not emit any pollutants.FCEVs can be fueled within 10 minutes and they can drive up to 300 miles.Over the last few years,a number of car manufacturers and government agencies have supported research and development activities that
33、accelerate fuel-cell technology.Unlike BEVs and PHEVs,the FCEVs do not use power grid to charge their batteries.Also,their onboard batteries are fairly small in size compared to those of BEVs,PHEVs,and HEVs.The disadvantages of FCEVs included having limited networks of hydrogen fueling stations and the technology being still in its infancy stages.小结与作业o What are Alternative fuels currently commercially available and closely attended?目前商业可用和受到紧密关注的替代燃料有哪些？目前商业可用和受到紧密关注的替代燃料有哪些？o What are the types of electric vehicles?电动汽车分为哪几种？电动汽车分为哪几种？o 背诵重要的专业术语背诵重要的专业术语
