A Commercially-Viable Electric Car 911919

The present traffic and pollution situation in our large cities and the inefficient use of the internal combustion engine car in city traffic, has been for a long time the catalyst to develop specific city cars, which can reduce the burden on the environment and be more economical to operate.
Several electric cars have been introduced in the past without success. The power/weight ratio of the present lead-acid batteries has been a limiting factor for the commercial success of an electric vehicle. In addition to this the high initial cost, limited range, and high operating cost have contributed to the low level of interest by the general public.
This paper describes the development of a commercially viable electric car based on a range-extending battery system. This car is also designed to be utilised with quick-change battery modules.
