Wind energy conversion system fed EV battery charging system using single phase bridgeless cuk converter is proposed in this paper. PMSG is employed in the WECS to convert the mechanical energy into electrical ac power. In standalone wind energy conversion systems, two stage ac-dc & dc-dc converters are employed to obtain the desired output. The bridgeless cuk converter employed in the proposed charger is a single stage converter which acts as rectifier as well as dc-dc converter. The bridgeless cuk converter converts the ac voltage generated from PMSG into a desired dc voltage for charging the battery of an electric vehicle. Thus, an intermediate stage of power conversion is reduced in the proposed system. Also, a simple output voltage controller is employed in the proposed system to charge the electric vehicle battery with constant voltage irrespective of the wind speed. The proposed off-board EV battery charger is simulated in Simulink environment of MATLAB software and the results obtained are furnished in this paper. The experimental investigation has been carried out in the developed laboratory prototype of the EV battery charging system and the obtained results are furnished in this paper.

Abstract This work is targeted to design an economical and self-reliant solar-powered battery charging scheme for light electric vehicles (LEV’s). The single-ended primary inductance converter (SEPIC) is utilized to enhance the performance of solar power and battery charging at various solar irradiances. Various unique attributes of a SEPIC converter offer the effective charging arrangement for a self-reliant off-board charging system. Further, the continuous conduction mode (CCM) function of the converter minimizes the elementary stress and keeps to maintain the minimum ripples in solar output parameters. A novel maximum power point tracking (MPPT) approach executed in the designed system requires only the battery current to track the maximum power point (MPP) at various weather situations. Both the simulated and real-time behaviors of the developed scheme are examined utilizing a battery pack of 24 V and 100 Ah ratings. These responses verify the appropriateness of the designed system for an efficient off-board charging system for LEV’s.

Energy storage systems (ESSs) are critically important for the future of electric vehicles. Despite this, the safety and management of ESSs require improvement. Battery management systems (BMSs) are vital components in ESS systems for Lithium-ion batteries (LIBs). One parameter that is included in the BMS is the state-of-charge (SoC) of the battery. SoC has become an active research area in recent years for battery electric vehicle (BEV) LIBs, yet there are some challenges: the LIB configuration is nonlinear, making it hard to model correctly; it is difficult to assess internal environments of a LIB (and this can be different in laboratory conditions compared to real-world conditions); and these discrepancies can lead to raising the instability of the LIB. Therefore, further advancement is required in order to have higher accuracy in SoC estimation in BEV LIBs. SoC estimation is a key BMS feature, and precise modeling and state estimation will improve stable operation. This review discusses current methods use in BEV LIB SoC modelling and estimation. The review culminates in a brief discussion of challenges in BEV LIB SoC prediction analysis.
