Development of 48 V starting systems for a two wheeler parallel hybrid

A hybrid two-wheeler requires two different types of motors for enabling the start stop operation-one is the traction motor and second is the starter motor. Two separate batteries are used in a conventional hybrid vehicle to power the motors as their operating voltages are different. This paper presents a novel concept of communising the operating voltage of the lower voltage rated-starting system and higher voltage rated-traction motor by using a single battery and compares with the conventional approach of using two separate batteries.
