Abstract

The invention discloses a PD protocol-based programmable power supply (PPS) mobile power system and a control method thereof. The mobile power system comprises a battery pack, a lithium battery protection module, a battery end current acquisition module, an H-bridge module, a DC-DC module, a master control MCU module, a VBUS current acquisition module, a multi-protocol chip resistance network acquisition module, a multi-protocol chip module and a TYPE-C interface module. The mobile power system can be suitably used for rapidly charging a PPS-supported consumer electronic product capable of low-voltage direct charging, low-voltage direct charging of the PPS-supported consumer electronic product is achieved, so that heat generation quantity of a consumer electronic product end is reduced, and a user experience of the consumer electronic product is enhanced.

Description

technical field [0001] The invention belongs to the technical field of mobile power supplies, in particular to a PPS mobile power supply based on the PD protocol. Background technique [0002] During January 2017, USB-IF released the latest USB-PD3.0V1.1 protocol, which mainly updated the standard of PPS (Programmable Power Supply), which can realize 20mv first-grade voltage adjustment, and can support up to 5A current. This standard is mainly used for low-voltage direct charging of consumer electronic devices. [0003] With the continuous increase of mobile phone battery capacity, charging speed has become a concern of mobile phone manufacturers and consumers. At present, there are two main fast charging methods: one is high-voltage and low-current charging. The advantage of this charging method is that it can inherit the previous wires without increasing the cost of the wires. However, the mobile phone needs to convert high voltage to low voltage before charging. until ...
