External standby battery system for mobile phone

Abstract

The invention provides an external standby battery system for a mobile phone. An external standby battery can be manufactured to adopt the style of a mobile phone protection shell or a mobile phone protection cover, can be reliably mounted on the mobile phone, is connected with the mobile phone through a contact and provides 3.7V voltage for the mobile phone. A detection module is arranged in the mobile phone and can automatically detect whether an external power supply is connected or not and prompt a user to switch a mobile phone power source power supply mode to an external battery power supply mode; when the external battery provides power for the mobile phone, the battery in the mobile phone is in an off-state. A USB charging interface is independently mounted on the external standby battery, so that charging can be realized through a mobile phone charger directly. The external standby battery system adopts the style of the mobile phone protection shell or the mobile phone protection cover, and can be directly mounted on the mobile phone, so that a user can carry the external standby battery system conveniently; the external standby battery directly supplies power to the mobile phone by adopting the 3.7V voltage, so that the charging and discharging frequency of the mobile phone battery is reduced, the service life of the internal mobile phone battery is prolonged, the phenomenon that the mobile phone is used while being charged by a mobile power supply is avoided and the user can conveniently charge through the mobile phone charger directly since the USB charging interface is independently mounted on the external standby battery.

Description

technical field [0001] The invention is used in a mobile phone, specifically a backup battery system that can be installed outside the mobile phone and can provide battery life for the mobile phone, and relates to electronic manufacturing technology and intelligent control technology. Background technique [0002] With the development of electronic technology and smart phones, people use mobile phones more and more widely, and the functional requirements of mobile phones are getting higher and higher, and the power consumption of mobile phones is also increasing. The battery life of most smart phones Can't meet people's requirements, many users are equipped with mobile power when using mobile phones, but mobile power is very inconvenient to use. And, when utilizing the mobile power supply to charge the mobile phone, the mobile phone is still used from time to time, which increases the loss of the battery of the mobile phone.
