Abstract.This paper investigates the discharge performance of two major lead-acid batteries, namely 12V/150Ah Gel and AGM sealed lead-acid batteries, when operating in stand-alone (offgrid) mode in photovoltaic (PV) based systems in United Arab Emirates (UAE). At harsh environmental conditions such as in UAE where the temperature can go to extremely high level in the summer, the battery performance and replacement cost increases the concerns about the reliability and economic feasibility of those batteries. This paper compares the discharge characteristics of those batteries through discharge tests performed on four similar batteries (two of each type). Experimental results of the discharge tests followed by a comparison between the two batteries are presented in this paper.

A study of state-of-health (SOH) prediction for diesel engine generator starting batteries is presented, the main purpose of which is to analyze the battery's state using the relationship between AC impedance and voltage. A sensing system capable of detecting battery open-circuit voltage and discharge current has been designed. The respective AC impedances at 100 and 50% battery SOH were obtained from a monitoring system, and linear regression was used to predict battery SOH. A new GS GTX7A-12B lead acid battery was used in the experiments and the results showed that there was a 11.265% difference between the actual battery SOH and that predicted by linear regression.

“…The energy transfer efficiency is the ratio of the charging and discharging capacity in the electrochemical reaction cycle of a battery. Recently, a sinusoidal ripple current (SRC) charging method has been proposed as a feasible solution for better charging performance with minimum battery ac impedance Z min [18], [19]. The experimental results in [18] show that, compared with the conventional CC charging method, the charging time, energy transfer efficiency, maximum rising temperature, and lifetime of the Li-ion battery in the SRC test have been improved by about 17%, 1.9%, 45.8%, and 16.1%, respectively.…”

A hybrid sinusoidal-pulse current (HSPC) charging method for the Li-ion batteries in electric vehicle applications is proposed in this paper. The HSPC charging method is based on the Li-ion battery ac-impedance spectrum analysis, while taking into account the high power requirement and system integration. The proposed HSPC method overcomes the power limitation in the sinusoidal ripple current (SRC) charging method. The charger shares the power devices in the motor inverter for hardware cost saving. Phase shifting in multiple pulse currents is employed to generate a high frequency multilevel charging current. Simulation and experimental results show that the proposed HSPC method improves the charger efficiency related to the hardware and the battery energy transfer efficiency.
