Arduino-Based Automatic Transfer Switching Charger for Lithium-Polymer Batteries

Most batteries are sustained through charging, and are a major resource needed to power most electronics. Putting an emphasis to the restrict fullness of having a monotonous input source and having no battery management system (BMS), the study focuses on designing and programming a BMS charger with Solar and AC inputs with the use of a microcontroller, testing the charging capabilities of the device and discharging of the lithium -polymer battery, and determining of the result of dual charging. These were achieved as the results reflected that using both inputs of AC and Solar, the energy efficiency is 91.35%. Furthermore, it is advised to use an alternative source like a battery to power up the system. Through this, a large portion of the community to be able to benefit through being able to utilize a cost-efficient alternative power source for occupational, and residential use through the device.
