Abstract

The invention discloses an intelligent extend power supply system of portable equipment, which uses an external auxiliary battery under the premise of using a main battery. The main battery and the auxiliary battery are respectively connected with a load-break switch monomer which comprises a PMOS diode, which are managed through a power management circuit. The intelligent extend power supply system combines a combined electric quantity display mode of a man-machine interface, the main battery is firstly charged forever, and the auxiliary battery is firstly used forever, and a hot-plug character is safely supported. The auxiliary battery which is designed according to the proposal has the advantages of various forms, security, long service span of an electric core, convenience, excellent user feeling and low production cost.

Description

technical field [0001] The invention relates to a power supply of a portable device, in particular to an intelligent extended power supply system of the portable device which is expanded by adding an external auxiliary battery on the premise of using a main battery. Background technique [0002] In today's life, various electronic products such as mobile phones, PDAs, and portable media players (PMPs) are used more and more widely, especially when traveling, business negotiations, and long-term business trips. indispensable. People hope that these portable devices can be used anytime and anywhere, especially now that portable devices have many functions, such as mobile phones, which can listen to music, play games, take pictures, watch TV, surf the Internet, etc., so there are more and higher requirements for batteries. The longer the time, the better. It is convenient and flexible to carry and use. The battery can be replaced anytime and anywhere. Of course, it is best to ...
