FIELD OF INVENTION

Embodiments of the present disclosure relates to managing speed of electric vehicles, and more particularly, to an arrangement for electromagnetic propulsion in a vehicle and a method to operate the same.

Electric vehicle (EV) is a vehicle that uses one or more electric motors or traction motors for propulsion. In a conventional approach, a constant supply of power is to be supplied to the electric motors in order to maintain the speed and keep the vehicle in motion at a required rate. In such approaches, the power is supplied by one or more rechargeable batteries, which can be recharged when the power in the one or more batteries is reduces. In such scenarios, the one or more batteries needs to be recharged immediately to keep the EV going. At times when the recharging stations are not available, it becomes difficult to use the EV. In addition, due to the requirement of longer milage, the capacity of the batteries is increased, due to which the size of the batteries increases and henceforth the overall weight of the EV also increases.

Hence, there is a need for an improved arrangement for electromagnetic propulsion in a vehicle and a method to operate the same to address the aforementioned issues.
