Design And Construction Of A Lead Acid Battery Charger

ABSTRACT

With the lack of centralized power grids, lead acid batteries have taken the place of one of the main energy source available in developing countries. With this in mind, our objective was to design and construct a cheap, versatile and efficient lead acid car battery charger which will interest and appeal to the cost minded customer. For extended battery and charger life, a protection circuit was incorporated to prevent the flow of excessive current which often result to damages in devices. The result of this design and construction was achieved through a regulated supply, protection circuit and switching circuit coupled to a charger circuit. Light emitting diode was used to indicate the status of the battery been charged.
