“…The frequency should be optimal to have a low impedance of the battery. Further, the magnitude of the ripple, which affects polarisation in battery and selection of components in the charger, need to be monitored [58][59][60][61] . Hence, a new power electronics converter topology for the charger and precise control of outputs (current and voltage) with the ability to reduce power quality for vehicle-to-grid issues is proposed in 60 .…”

Li-ion batteries are widely used in electric vehicles because of their promising characteristics that meet high specific power and energy density requirements. The only setback is the capacity fading due to degradation in Li-ion batteries. The rate of capacity fade in Li-ion batteries in EVs vary based on the charging rate, changes in internal cell temperature and external ambient temperature, and user driving patterns. Since the Li-ion battery is electrochemical, determining the actual cause of degradation at a particular instant and constraining the rate is a big challenge. Further, the causes are related to parameters which are chemical, electrical and mechanical. In this work, the causes of degradation are studied by analysing the variation of parameters for multiple charge types and rates at different ambient temperatures. The analysis leads to developing a new battery friendly charging scheme suitable to fast charge battery at different ambient temperatures appropriately and constrain battery degradation.

“…Accordingly, the usage of battery charger for automotive applications is developing continuously and actively [2]. In the battery charger structure, active front‐end (AFE) rectifiers are often used as an attractive topology, which is responsible to deliver power from the AC grid to the DC side with unity power factor [3].

This study proposes a control technique based on integral switching surface sliding‐mode control for three‐phase pulse‐width modulation (PWM) rectifier. The proposed control system is based on the combination of a conventional proportional–integral (PI) controller and with two decoupled first‐order sliding‐mode (PI‐FOSM) current controller. A set of integral switching surfaces based on the state‐space equation are designed in the internal loop to force the grid currents to track their desired values. The proposed control approach improves the transient response and minimises the steady‐state error under uncertainty. In addition, a conventional PI controller is also employed for the voltage regulation loop and generating the current reference of inner loops. In the controller design, all parameters of the system are considered with bounded perturbations in the design of control law. The main advantage of the proposed controller is robustness property against variations of entertained PWM rectifier parameters and external disturbances. The proposed PI‐FOSM can improve transient performance and can decrease of the harmonic components under steady‐state condition. In order to validate the theoretical contributions of this study, the performance of the proposed controller has been investigated by using a prototype laboratory.

This study focuses on considering battery one time constant model in the design of controllers of a two-stage AC/DC and DC/DC battery charger using the small-signal approach. For this aim, small-signal models of DC/DC and AC/DC converters and also the battery model are obtained. Moreover, the effect of disturbance terms are analysed to be omitted in controller loops. Simulation and experimental results of a 1 kW laboratory prototype show appropriate performance of designed controllers in tracking reference signals. Also, tuned controllers using this approach have guaranteed unity power factor and low total harmonic distortion. Furthermore, a complete charge cycle of a lithium-ion battery evaluates the performance of the converter in different constant current/voltage controlling modes. In comparison with restive model consideration, results show a more accurate model with grater damping ration and better stability characteristics.
