Problems solved by technology

However, at this time, mobile phone A and mobile phone B both occupy the charging interface. When one or both mobile phones are out of power, they will not be able to charge the mobile phone. The only way to stop the interconnection between mobile phone A and mobile phone B is to turn off the charging interface of the mobile phone. Release to use the charger or power bank to charge the mobile phone

Abstract

The invention discloses charge control equipment. The charge control equipment at least comprises following ports: a first port, a second port and a power port; the charge control equipment further comprises a controller, wherein the first port is used for being connected with a first mobile phone; the second port is used for being connected with a second mobile phone; the first port and the second port are interconnected through a universal serial bus, so that the first mobile phone and the second mobile phone are interconnected to realize screen expansion; the power port is used for being connected with a power source; the controller is used for charging the first mobile phone or the second mobile phone by the power source. The charge control equipment can still charge the mobile phones when the two mobile phones are subjected to two-screen interconnected expansion, so that two-screen interconnected expansion is not affected when either or both mobile phones are out of power.

Description

technical field [0001] The present invention relates to the technical field of charging of mobile devices, in particular to a charging control device and a charging control method. Background technique [0002] At present, when the dual-screen interconnection expansion is realized between two mobile phones, the two mobile phones are connected to each other through a power transmission (PD, Power Delivery) line, and a dedicated data communication link is required for communication handshake. This method has not yet been popularized. And the cost is high. [0003] And when using PD to connect two mobile phones, the communication direction and charging direction must be consistent, and the reverse situation is not allowed. For example, mobile phone A charges mobile phone B, then only mobile phone A can send data to mobile phone B. [0004] For example, when mobile phone A and mobile phone B are connected to each other, mobile phone A controls mobile phone B to display required...
