Abstract

The invention relates to a portable solar mobile power supply for a notebook computer. An integral circuit structure comprises a main control circuit, a solar maximum power point tracking (MPPT) charging system, a lithium battery protection circuit, a high-power boosting circuit, two high-power voltage reduction circuits, an output filter circuit and a light-emitting diode (LED) liquid crystal display. The main control circuit is respectively connected with the lithium battery protection circuit, the high-power boosting circuit, the two high-power voltage reduction circuits, the output filter circuit and the LED liquid crystal display. The portable solar mobile power supply has the advantages that portability and practicality of the solar mobile power supply are improved by novel circuit and casing shape structural design; a maximum power tracking technology is utilized, and efficiency of a solar cell panel in charging the solar mobile power supply is improved; automatically optimized high-power components are adopted to form the boosting circuit and the voltage reduction circuits, the portable solar mobile power supply has the output characteristics of being high in efficiency and capable of switching voltage, software and hardware double-layer overcharge, over discharge, overcurrent and over-temperature protection is adopted, the portable solar mobile power supply has better safety, and good reference significance is provided for design of the solar mobile power supply.

Description

technical field [0001] The invention relates to a portable solar notebook mobile power supply, in particular to a novel portable mobile power supply. The mobile power supply can be supplemented by solar panels, and the built-in polymer lithium battery can save the energy converted by the solar panels. The mobile power supply has a standard USB slot (5V / 2A output), 4.8 / 1.7mm high-power DC output interface (19V, 16V, 12V / 4.5A, 9V / 1.5A output), 5.5 / 2.1mm high-power DC input The interface (15-20V / 3A) can intelligently select the output voltage to charge a variety of mobile phones, notebook computers and digital devices. Background technique [0002] With the continuous improvement of people's living standards, there are more and more types and quantities of portable digital products, such as mobile phones, tablet computers, digital cameras, notebook computers, and healthcare equipment. These devices all use batteries, but the built-in batteries of these devices always...
