Abstract Nowadays, automobile makers will be required to produce new technologies that improve automotive performance while still satisfying the ever increasing comfort demand of drivers. On the other hand, one of the best ways for achievement of conventional vehicle changing to hybrid case is trustworthy simulation result and using of driving realities. For this objective, the present work investigates the vehicular performance characteristics of alternative vehicle types. The vehicular performance characteristics of three types of alternatives have been presented. The first alternative is theoretically studied for hybrid electric vehicle performance characteristics evaluated based on highway driving cycle, while the second alternative is also theoretically studied for hybrid electric vehicle and evaluated based on urban driving cycle. The third alternative is designed, constructed; based on extra urban driving cycle and studied theoretically and experimentally for battery electric vehicle. A historical review of the available published work has been introduced and showed the need for further research work in this area. The comprehensive vehicle theoretical and experimental analysis techniques are presented which describe the way of dealing with the alternative vehicle performance are given. The experimental setup, instrumentation system, construction, design and test procedure are presented. In addition, the description of the types of standard driving cycles and vehicles used is included. In addition, in this study a practical prototype of a battery electric vehicle (BEV) was designed and constructed to represent an example of the alternative fuel vehicles. The battery electric vehicle (BEV) specifications can be briefed in using a DC electric motor, 15 HP, 3200 rpm, operating on 72 volt DC, while for the source of energy a specific type of batteries was used (US 8VGC XC deep cycle lead acid batteries for the 8V 170 amp hours (AH)). Depending on the calculations, eight batteries were fitted in the electric vehicle, and this would give a battery pack of 10.88 kWh. The batteries have been configured in two rows of eight series connected batteries creating a battery pack of 64V and 170 AH. According to the theoretical calculations and experimental tests, the battery electric vehicle attains a maximum velocity of 70 km/h. In addition, the present study conducted a set of experimental tests were carried out to evaluate the performance of implemented battery electric vehicle during a various operating conditions. The results indicate that the theoretical simulation information were found to be compatible with those of experimental information of the designed prototype. Furthermore, the type of alternative vehicles shows extreme benefits of performance for electric and hybrid vehicles to contribute good design. |
