A Li-ion battery charging design for wireless medical implants is presented. Not only the power density is limited in the medical implants, but also the inherent lack of efficiency in a wireless powered system restricts the stability of power supply for medical implants. Therefore, a simple and...
For example, undercharging a Li-Ion battery by only 100 mV (-2.4% for a 4.2-V Li-Ion cell) results in about a 10% loss in capacity. Since the room for error is so small, high accuracy is required of the charging-control circuitry.To achieve this accuracy, the controller must have ...

This paper analyzes and simulates the Li-ion battery charging process for a solarpowered battery management system. The battery is charged using a non-inverting synchronous buck-boost DC/DC power converter. The system operates in buck, buck-boost, or boost mode, according to the supply voltage...
Energy storage has become a fundamental component in renewable energy systems, especially those including batteries. However, in charging and discharging processes, some of the parameters are not controlled by the battery's user. That uncontrolled working leads to aging of the batteries and a reductio...
