Fast charging power source capable of automatically adjusting and distributing power and use method thereof

Abstract

The invention discloses a fast charging power source capable of automatically adjusting and distributing power, which comprises a power source body, one side of the power source body is fixedly connected with a USB-A output port and a USB-C output port, a main control circuit MCU is fixedly connected with the inner part of the power source body, the output end of the main control circuit MCU is connected with the input end of the USB-A output port, and the main control circuit MCU and the PD protocol control module realize two-way connection, and the invention relates to the technical field ofelectronic devices. The PD / QC fast charging power source capable of automatically adjusting and distributing power and the use method thereof can enable the circuit main control chip to combine witha peripheral auxiliary circuit to automatically detect and judge the current operating state of the charger and carry out dynamic power distribution and adjustment under a loading condition, the fastcharging requirements under different conditions can be met, the volume of the product can be reduced by 1 / 3 of the volume of the original product when the fast charging requirements of 30W PD fast charging and 18W QC fast charging are met, and the product is more convenient to carry, and the manufacturing cost of the product is reduced by more than 15% of the original cost.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a fast charging source for automatically adjusting and distributing power and a method for using the same. Background technique [0002] Mobile power is also called power bank, travel charger, etc. It is a portable charger that integrates power supply and charging functions. It can charge digital devices such as mobile phones and tablet computers anytime and anywhere. Lithium batteries are generally used as power storage units. Convenient and fast, the power bank automatically allocates and adjusts the dynamic power according to the actual use conditions and conditions. Similarly, when consumers need a two-in-one power bank with 30W PD fast charging and 18W QC fast charging, use automatic adjustment and When using the fast charging source technology for power distribution, only one power bank with a total power of 30W is required to meet user requirements.
