### Example: Patent Application Abstract for a “Smart Solar-Powered Battery Charger”

**Abstract:**

The present invention relates to a smart solar-powered battery charger designed for portable electronic devices. The charger integrates an advanced photovoltaic cell array with an energy management system that optimizes power generation and distribution. The system utilizes a microprocessor to dynamically adjust the charging output based on ambient light conditions and the power requirements of the connected device. A built-in battery storage unit is capable of storing excess energy generated during peak sunlight hours, which can be used to charge devices during low-light or nighttime conditions. Additionally, the charger features wireless communication capabilities that enable users to monitor charging status and control settings via a mobile application. The invention provides an eco-friendly, efficient, and reliable solution for charging electronic devices in off-grid or outdoor environments, while ensuring optimal energy use and prolonging battery life.
