Working Principle of Lithium Battery Charger

The charger operates using a controlled charging algorithm optimized for lithium-ion cells. When a battery is inserted and USB power is applied, the charger delivers a constant current until the battery reaches its nominal voltage. It then switches to constant voltage mode, gradually reducing current until the battery is fully charged.

This method ensures safe charging, minimizes battery stress, and extends battery lifespan. Once charging is complete, the charger automatically stops or reduces current to prevent overcharging.
