“…In order to verify the correct operation of the optical fiber in real measurements in batteries, tests were carried out during the processes of charging and discharging using a testing bench which includes an automated system for the charge and discharge of batteries with different charging regimes [ 28 , 29 ]. Figure 13 shows the real time results for a slow charge (15 A), medium charge (51 A) and fast charge (150 A).…”

This article describes a multi-point optical fiber-based sensor for the measurement of electrolyte density in lead-acid batteries. It is known that the battery charging process creates stratification, due to the different densities of sulphuric acid and water. In order to study this process, density measurements should be obtained at different depths. The sensor we describe in this paper, unlike traditional sensors, consists of several measurement points, allowing density measurements at different depths inside the battery. The obtained set of measurements helps in determining the charge (SoC) and state of health (SoH) of the battery.

“…Moreover, bipolar pulses produced by inverters can be used in the reflex charging mode [24]. Compared with the traditional DC power charging process, the reflex charging mode can speed the charging process up and extend the life of batteries [21,[25][26][27]. Generally, inverters are classified into voltage source inverters (VSIs) and current source inverters (CSIs) by considering the structure of the inverters [28][29][30][31].…”

Current source inverters (CSIs) use inductors as the major component to store energy. Compared with voltage source inverters (VSIs), CSIs have two advantages: 1. They can avoid the converter failure caused by capacitor failures, and 2. The load current does not increase with load mutation or even short-circuit failure. Therefore, CSIs can be a promising technology for EV charging. However, the waveforms, parameter design procedure, and power efficiency are still unclear. Therefore, it is unclear if CSIs are suitable for EV chargers. This article derives the closed-loop equations of the critical components, including the inductor current waveforms and the voltage ripple. Especially, the load over-voltage phenomenon is derived and verified to further ensure the reliability of the CSI system. Based on the derived equations and reliability requirements, the parameter design procedure is proposed. The power efficiency of both the Si- and SiC-based converters are derived and compared to remove the barrier of applying CSIs in EV chargers in the industry. Our simulations and experiments verify the correctness of the system modeling, over-voltage phenomenon, and power efficiency. All the simulation files (using PLECS) and calculation files (using MATLAB) are attached for the readers to verify and/or further modify.

“…This increased charging efficiency to a great extent when compared to the old charge modes. In 2006, Marcos proposed a fast charge control [6] method, and the final experimental data showed that the battery temperature rise was improved effectively, which had an indirect effect on charging efficiency. In 2012, Hsieh and Shih compared the charging efficiency in different MPPTs [7].…”

This study used a field-programmable gate array (FPGA) with a Xilinx Spartan-3 FPGA to implement Reflex charge control in a dual-axis solar tracking system with maximum power point tracking (MPPT). The chaos embedded particle swarm optimization method was used to search for the optimum gain constants of the PI controller and the Reflex charging frequency. This scheme not only increases the output power of solar panels but also has a significant effect on switching loss and oscillation of solar charging. The experiment results showed that the proposed method can also significantly improve temperature rise, and that charging efficiency is also better than it is in a traditional charge mode. The results also showed that charging power was enough for solar tracking and the requirements of the charging system. The most significant contribution of this paper is that the scheme can be applied to any active solar tracking and charging system.
