Embodiment Construction

[0083] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application , but not all examples. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0084] In related technologies, when the master device and the slave device are connected through the USB interface, the master device will charge the slave device. For example, when the VR / AR device is connected to the mobile phone through the USB interface, the mobile phone will act as the master device, and the VR / AR device will act as the slave device. The master device charges the slave device. As long as the...

Abstract

The invention provides a charging method and device. The method is used in slave equipment, the slave equipment is connected with master equipment through a connecting line, and the method comprises the steps that the current remaining electric quantity of the master equipment and the current remaining electric quantity of the slave equipment are obtained every preset time, and the remaining electric quantity is the percentage of the remaining battery electric quantity in the total battery electric quantity; and whether the current remaining electric quantity of the master equipment and the current remaining electric quantity of the slave equipment meet a first preset condition is determined, and if so, the path current of the master equipment entering the slave equipment is set to be less than or equal to a preset current threshold. Therefore, the balance of the remaining electric quantity of the master equipment and the slave equipment can be ensured, and the used electric quantity of the master equipment is ensured.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a charging method and device. Background technique [0002] Mobile phones are the core of current personal electronic devices and have a wide range of users. There are currently many external devices that use mobile phones as the main device. Some external devices require power from mobile phones, such as virtual reality (Virtual Reality, VR) / augmented reality ( Augmented Reality, AR) field, when some VR / AR devices have batteries, when the VR / AR device is connected to the mobile phone through the Universal Serial Bus (USB) interface, the mobile phone will act as the main device, and the VR / AR The device acts as a slave device, and the master device charges the slave device. However, sometimes the battery power of the mobile phone is exhausted by the slave device and the battery power of the slave device is sufficient. The power of the two is not balanced, a...
