Abstract
Conference Title: 2018 International Conference on Innovative Trends in Computer Engineering (ITCE) Conference Start Date: 2018, Feb. 19 Conference End Date: 2018, Feb. 21 Conference Location: Aswan, Egypt The lead acid batteries are used in several applications. In the literature, there are many different charging techniques. It is important to investigate the circuit techniques and control methods for lead acid battery charging. Studying and comparing among different charging control methods and characteristics are very important to be presented. In this paper, MATLAB program is used to monitor the charging and discharging current and battery's temperature during charging and discharging times of lead acid battery. To increase the lifetime of the lead acid battery, it is necessary and important to design a charger which has some characteristics such as lower temperature during charging, and fast charging. The charging functions (temperature during charging, charging time) of different charging techniques (constant current, two step constant current, constant voltage, constant current-constant voltage, pulse charging, reflex charging) are studied and presented. The simulation results are carried out on the lead acid battery of 50 AH.
