“…9,10 However, much of the rest of the vehicle is similar to a conventional vehicle; most BEVs still use a relatively conventional transmission system, including a clutch, a shaft drive, a gearbox and a differential. As with an ICE, the transmission affects the overall efficiency and the vehicle mass.…”

“…13 It is clear that electric vehicles have an advantage over traditional ICE vehicles in that the designer has considerably more choice in terms of the powertrain architecture. 10 Whereas a conventional vehicle must almost always be a single-drive configuration, a BEV can have a single-drive motor, two independent-drive motors with reducing gears, two independent motors with direct drive or even in-wheel drive. 9,10 There is more opportunity for optimising an architecture for a particular usage pattern.…”

“…The typical BEV in today’s market differs from an ICE vehicle in that, instead of having an engine and a fuel tank, the BEV has an electric machine and an electric energy storage unit. 9, 10 However, much of the rest of the vehicle is similar to a conventional vehicle; most BEVs still use a relatively conventional transmission system, including a clutch, a shaft drive, a gearbox and a differential. As with an ICE, the transmission affects the overall efficiency and the vehicle mass.…”

“…As with an ICE, the transmission affects the overall efficiency and the vehicle mass. 10 Electric machines have rather different characteristics from thos of ICEs; the typical electric machine provides its maximum torque at a low speed, in comparison with an ICE’s peak torque at a particular speed. Consequently, electric vehicles can be operated with a single-ratio or double-ratio transmission 9 rather than the five-or-more-speed transmission found in an ICE vehicle.…”

Electric vehicles are becoming more popular in the market. To be competitive, manufacturers need to produce vehicles with a low energy consumption, a good range and an acceptable driving performance. These are dependent on the choice of components and the topology in which they are used. In a conventional gasoline vehicle, the powertrain topology is constrained to a few well-understood layouts; these typically consist of a single engine driving one axle or both axles through a multi-ratio gearbox. With electric vehicles, there is more flexibility, and the design space is relatively unexplored. In this paper, we evaluate several different topologies as follows: a traditional topology using a single electric motor driving a single axle with a fixed gear ratio; a topology using separate motors for the front axle and the rear axle, each with its own fixed gear ratio; a topology using in-wheel motors on a single axle; a four-wheel-drive topology using in-wheel motors on both axes. Multi-objective optimisation techniques are used to find the optimal component sizing for a given requirement set and to investigate the trade-offs between the energy consumption, the powertrain cost and the acceleration performance. The paper concludes with a discussion of the relative merits of the different topologies and their applicability to real-world passenger cars.

“…It is mentioned that, BEV can significantly reduce air pollution if charged completely from renewable energy sources [2]. Besides that, BEVs have advantages such as high level of energy efficiency, zero tailpipe emissions, low rate of noise, less moving parts thus requiring less maintenance, and regenerative braking [3].…”

Battery electric vehicle is a promising candidate for future passenger vehicles due to its potential to reduce air pollution, high energy usage effficiency, and has regenerative braking. However, due to the limited range and price, potential vehicle onwers are reluctant to consider owning an EV. Moreover, the limited range of BEV has caused range anxiety among the driver. Other than improving the technology of BEV to increase the driving range, range estimator can be useful in reducing the range anxiety of BEV drivers. The conventional range estimator is used like a fuel gauge; to give a general guideline on when to recharge the vehicle and is not absolute. To further increase the confidence in BEV driving, trip based range estimation can be used in parallel with the conventional method to reduce the range anxiety.
