Abstract
The rapid evolution of technology has propelled an era where consumers expect not only seamless functionality but also heightened safety standards from their electronic devices. Consequently, the need for battery chargers that transcend the conventional paradigm and integrate essential safety features has become paramount. The conventional charging process, while efficient, often lacks protective mechanisms against reverse current flow, posing significant threats to both the rechargeable batteries and the charging circuitry. Recognizing this gap, the focus of this research project is on the meticulous design and construction of a 20A,12/24v battery charger that not only ensures effective charging but also incorporates a robust reverse current protection mechanism. The project focuses on developing a reliable and efficient battery charging solution for various applications. This battery charger is designed to handle charging currents up to 20A and is compatible with both 12V and 24V battery systems. The design incorporates a robust charging circuit that ensures efficient and safe charging of batteries, along with features that protect against reverse current flow, which can damage the batteries and the charger. Key components of the system include a power transformer, rectifier, voltage and current regulators, and a reverse current protection mechanism. The project emphasizes user safety and battery longevity by implementing automatic switching between 12V and 24V modes, as well as integrating safety features to prevent overcharging and overheating. Comprehensive testing was conducted to validate the charger's performance under different conditions, ensuring it meets the required standards for efficiency and reliability ...
