The present invention proposes a parallel multi-source power supply system with unified output, which includes the first power supply having the first and the second USB-C connectors, the second power supply having the third USB-C connector electrically connected to the first power supply in parallel through the second USB-C connector. The first power supply is configured to operate in a constant current and constant voltage (CCCV) mode to output the first power, while the second power supply is configured to operate in a constant voltage (CV) mode to output the second power. The second power is transferred to the first power supply and unified with the first power to power an external electronic system through the unified output. The amount of the second power transferred to the first power supply is determined by a charging agreement through communicating between the first power supply and the external electronic system.

Parallel multi-source power supply system with a unified output

An intelligence AC to DC maximum power charging management method of a battery includes providing a battery charger having a power conversion unit coupled to a charging control device, which contains a micro-controller, a voltage detection unit, a current detection unit, a temperature sensor, and a communication port, and providing a battery pack electrically connected to the battery charger enabling the charging controller to provide charging management for the battery pack, wherein the micro-controller can calculate charging power through received battery voltage, battery charger current, and temperature of the battery charger and tracking the maximum output charging power.
