Abstract
A conceptual study to configure battery and extended range electric vehicles (A-segment) for emerging markets is presented. The clean sheet design approach begins with the Vehicle Technical Specifications for emerging markets, which differ appreciably from those for the developed markets. These requirements along with tradeoff studies for energy and power requirement as a function of vehicle mass, decide the specifications for the sub-systems such as battery, Auxiliary Power Unit (APU) and drive unit. Possibility of a single vehicle platform for both BEV/EREV variants is explored. Mass of BEV/EREV is estimated using sub-system mass influence coefficients. A preliminary cost estimation is carried out for the EREV/BEV variants with regard to material cost, initial on-road cost and ownership cost and compared with those for a typical Internal Combustion Engine (ICE) based vehicle of similar size. The study shows that two different variants - (i) BEV with 200 km (without climate control) and EREV with 100 km (without climate control) of extended range can be configured within the wheelbase and overall length of about 2230 mm and 3380 mm respectively. Cost analysis shows the ownership cost for the EM-EREV can be appreciably less than that for the corresponding ICE vehicle although the initial cost may be higher than the corresponding ICE vehicle.
