A Practical Lithium Ion Battery Charger for use with Solar Panels

摘要

Increasingly the number of battery operated devices use rechargeable lithium ion batteries as the power source. Common charging solutions for these batteries include wall adapter based chargers and universal serial bus (USB) based chargers. While these chargers provide a low cost solution for charging batteries, these chargers suffer from a common drawback for use with solar power in that they depend on a constant power source for their normal operation. Chargers which
