“…According to Table 1 the proposed BCS topology improves the system efficiency. The highgain step-down converter and control scheme results in easy dynamic modeling and simple experimental implementation compared to previous works [13] and [14]. Moreover, it is not necessary to include equivalent circuits to model the battery performance as in [15] and [17], since a bank of lead-acid batteries is considered.…”

“…The battery charging process ends when the battery current reaches a minimum value. Thus, the CC-CV charging profile is the most widely used charging method due to the facility of adapting it to different types of batteries and control schemes [12], [13], [14], [15], [16], [17]. In addition to electronic power converters and battery charging profiles, the BCS employs a battery management system (BMS) designed based on the battery charging profile and used for the battery charging process.…”

In this paper, a model-based control scheme for a DC-DC power converter as a battery charger is presented. The proposed DC-DC converter for this task is a high-gain step-down converter based on the switched inductor concept. Thus, the considered topology is able to highly reduced the output voltage on a single stage compared to traditional step-down converters. The proposed control strategy is aimed at fulfilling the requirements of the constant current and constant voltage algorithm widely used for battery charging purposes. Given the structure of the system model, the proposed control scheme results in a multiloop controller, which is structured by a PI current control loop and a PI voltage control loop. During the constant current stage, the system is required to inject constant current into the battery while the voltage freely increases. Thus, the current control loop maintains the input battery current at a constant reference value. On the other hand, in the constant voltage stage, the battery is regulated to a desired constant value. Hence, in the end, both control loops act on the system to fulfill the objective. An external battery management system is aimed at controlling the transition between both modes, considering the physical thresholds of current and voltage required by the battery to guarantee the successful charging process. Finally, the performance of the proposed control strategy for battery charging is assessed on an experimental setup.INDEX TERMS Battery charger, constant current and constant voltage, DC-DC converters, model-based control.

“…These hybrid topologies ensure the CCCV charging modes with changes in the state of the battery parameters. Constant charging methodologies increase the life span of the batteries [38,39]. The cascaded structure of the LC-network, T-network and π-network ensures constant voltage and current delivery from any type of source [40].…”

The surge in demand for eco-friendly transportation and electric vehicle (EV) charging infrastructure necessitates innovative solutions. This study proposed a novel approach to charging slow-moving vehicles, prioritizing efficiency and minimizing output pulsation. Central to the research is the development of a receiver-side power-regulated constant charging system, focusing on power regulation and maintaining consistent charging parameters. This system integrates a receiver-side pulse density-modulated active bridge rectifier, dynamically adjusting driving pulse density to regulate delivered power. Additionally, a receiver-side reconfigurable compensation network ensures constant current and voltage delivery to the charging device, eliminating the need for an additional D.C.-D.C. converter. A 3.3 kW charging structure employing a multi-leg inverter topology and energizing four ground-side transmitter pads exemplifies the proposed approach. The vertical air gap of charging pads is 150 mm, and the system achieves a maximal efficiency of 93.4%. This innovative strategy holds significant promise for advancing sustainable transportation infrastructure and meeting the evolving demands of the EV market.
