Rechargeable batteries like Lithium-ion and Zinc batteries have high levels of energy and power density among other electrochemical batteries such Lead acid battery etc. The high level of energy and power density of these batteries makes them suitable as the energy storage in electric, hybrid electric vehicle, and plug-in vehicles (EV/HEV/PHEV). One of the important requirements in automotive batteries is to monitor their state-of-charge (SOC), state-of-health (SOH), terminal voltage, open circuit voltage and temperature parameters on line. Open circuit voltage, is one of the parameter used for predicting the SOC in the battery, which is not readily available during charge and discharge cycles. Online comparison of the predicted and measured terminal voltage provides a tool for calculating the SOC and SOH. In this research paper attempt is made to design the system for online monitoring of battery performance parameters for battery operated vehicles or plug-in vehicles.

This paper presents an inductive power transfer technology for the charging application of an electric vehicle (EV). The inductive power transfer has been an essential and effective way of transferring power to EV on the run. The frequency mismatch in between primary and secondary of inductive coupling is a major problem under a dynamic load condition of EV. In this paper, a suitable material and coil winding are chosen for primary and secondary coil to meet out the maximum inductive power transfer between the primary and secondary. Hence, a phase locked loop subsystem has been implemented for rectifying the frequency mismatch in between primary and secondary. The range of frequencies for which efficiency have been studied and analyzed under different load conditions. Finally, results have been obtained for a maximum power coupling as compared with conventional wireless transfer schemes.
