Parallel mild hybrid equivalent to the Tata Safari

Abstract

The vehicle range provided by a fully charged battery module in any electric vehicle is no match to the range provided by the internal combustion engine driven vehicles with full tank gasoline or diesel. This limitation of electric vehicles paved way for the evolution of hybrid electric vehicles. Among the various known architectures for hybrid electric vehicles, the parallel mild hybrid is expected to be the right candidate to be introduced in a developing country. This is because the size of the electric powertrain in such vehicles shall be relatively smaller compared to the other vehicle architectures and hence shall be less costly compared to the electric vehicle or other hybrid electric vehicle configurations. This paper aims at explaining the procedure of deriving a parallel mild hybrid vehicle equivalent to Tata Safari, a passenger vehicle already available in Indian market. The paper also compares the performance specifications of both vehicles and determines the losses in the proposed vehicle during the normal cruising mode and regenerative modes while traversing a typical Indian urban driving cycle and an Indian highway driving cycle.
