7、Hydrogen Fuel-cell Electricity Hybrid（electricity + conventional fuels）1.2 Overview of Alternative Fuel vehicles 替代燃料汽车概述 Electrical Energy The basic principle of an electric car is that it is powered by an electric motor rather than a petrol or diesel engine. The electric car itself is non-pollutin

8、g and an attractive transportation means from the standpoint of preserving urban environment. Electric cars run purely on electrical energy generated by large battery units. The electric car has one or sometimes two large AC motors and a single- or double-speed reduction gearbox to drive the wheels.

9、1.2 Overview of Alternative Fuel vehicles 替代燃料汽车概述 Hybrid The energy density of the power battery of an electric car poses serious problems; its travel range per full charge may be more or less 100km. So, a form of transportation called “hybrid” that combines two or more forms of power and converts

10、this into propulsion power in a direct or indirect way is deploying widely. These hybrid vehicles often use internal combustion engine and electric motor or motors to drive the wheels. The majority of todays hybrid cars are petrol-electric, but as technology advances we are seeing diesel-electric hy

11、brid cars.1.2 Overview of Alternative Fuel vehicles 替代燃料汽车概述 Fuel-cell A fuel cell is an electrochemical energy conversion device. A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. The fuel cell is powered with pure hydrogen, but hydrogen

12、is difficult to store and distribute. Methanol is a liquid fuel that has similar properties to gasoline. It is just as easy to transport and distribute, so methanol may be a likely candidate to power fuel-cell cars.1.3 Classifications of Electric Vehicles 电动汽车的分类New Words and Phrasesaccelerationksel

18、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 Vehicles 电动汽车的分类1

19、.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 internal combustion engine，as shown in Figure 1.5. The battery provided electric energy to the motor and used as the ener

20、gy 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Fig.1.5 Drive train schematic diagram of BEV 1.3 Classifications of Electric Vehicles 电动汽车的分类 Battery electric vehicles do not have tailpipe emission

21、s; 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 20 kWh to 85 kWh with all-electric-range (AER) of 80 300 mil

22、es. 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1.3.2 Hybrid Electric VehiclesHEVs are primarily powered by internal combustion engines, which use conventional fuels such as gasoline and diesel. These vehic

23、les 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 market in 1997, when Toyota introduced the Prius model, and two years later Honda introduce

24、d 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1.3.3 Plug-in Hybrid Electric Vehicles As shown in Figure 1.6, PHEVs employ both an electric motor and an internal combustion engine (ICE), which can use gasoline or

25、 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 driving range is higher than that of BEVs. As a result, the main advantage of PHEVs is employing both engines types, which helps

26、 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 combustion engine is used when the battery is depleted, during intensive cooling or heating, or during rapid acceleration.1.3
