Efficient Wireless Charging of Batteries With Controlled Temperature and Asymmetrical Coil Coupling

Present work considers the case of stationary Wireless charging (WC) of an Electric Vehicle (EV) with Li-ion batteries. Coil misalignment is quite common in WC and also charging of a Li-ion battery requires proper care. In this view asymmetrical coil system with suitable charging strategy has been proposed. At first analytical electro-thermal model of Lithium ion battery is developed to get preliminary behaviour and further analysed through 1D model in Finite Element Method based software to comment on heat distribution during charging. Evaluation of electrical parameters of WC with LCLS compensation is carried out and validated through MATLAB simulation. At the end proposed strategy has been extended to the case of temperature regulated charging.
