Implementation of a New Charging Feature with SOC Estimation in Electric Vehicles

Shamna P V, Beena M Varghese

This paper presents a new charging feature in Electric Vehicles using PIC. Algorithm works utilizing the back electro motive force(BEMF) produced by the motor. The structure is a buck-boost converter chip, which transfers the energy stored in battery for driving motor, and can recycle the energy resulted from the back electromotive force (BEMF) to charge battery by changing the operation mode. A relay is employed for switching the buck-boost converter. An algorithm for State-of- Charge(SOC )estimation is also proposed.
