Smart Charging Module for Controlled Charging of Mobile Devices

The existing USB BC1.2 Protocol in contemporary electronic devices relying on USB charging for Li-ion batteries poses a significant challenge today. The dependency on charging for data transfer, dictated by the protocol, results in continuous charging during extended data transfers. This constant charging contributes to accelerated battery wear when there is a requirement for continuous data transfer. This study proposes a charge-controlling module, providing stabilized power input, enabling on-request data access, and actively managing battery health to mitigate degradation. The designed module further employs a battery-capacity-centric algorithm, accommodating diverse device specifications to effectively address economic, safety, and operational concerns associated with continuous charging.
