This paper presents a control strategy of integrated switched reluctance motor(SRM) base on split-winding method. A novel SRM converter topology which integrated driving mode and battery charger are proposed in EV application. Due to integrate the winding of motor, the boost inductance is limited by the phase winding of the motor, so the performance of the integrated battery charger is cut down. In...
Battery energy storage management for electric vehicles and hybrid electric vehicles is the most critical enabling technology. A battery system is a complex electrochemical phenomenon whose performance degrades with ageing and the existence of varying material design. Moreover, it is very tedious and computationally very complex for monitoring and controlling the internal state of battery's electrochemical...
For the development of an innovative battery management system an accurate and a reliable technique for reliability of battery operations for a hybrid/electric vehicle. This paper illustrates an online SOC estimation method of a LiFePo4 battery for applications in electric vehicles by using a particle filter. Additionally, a five comparison experiments with different open circuit voltage curves exhibits...
As is known to all, an accurate on-line estimation of the battery capacity is important for forecasting the EV driving range. But because of the different driving environment and the property of the battery, it is hard to estimate the capacity of the battery pack. This paper presents an unscented Kalman filtering method to estimate the state of charge of LiFePO4 battery pack. Five comparison experiments...
Regenerative braking can improve energy usage efficiency and prolong the driving distance of electric vehicle per charge, effectively. In the paper, we design a sugeno's fuzzy logic controller which has four inputs including driver's braking requirements, vehicle speed, batteries' SOC, batteries' temperature and one output which is the regenerative braking force. We do some improvement on the force...
