Embodiment Construction

[0017] The specific implementation of the solar charging device provided by the present invention and the charging method using solar cells will be described in detail below in conjunction with the accompanying drawings.

[0018] attached figure 1 Shown is a schematic structural view of a specific embodiment of the solar charging device of the present invention, including a solar panel 11 , a charging module 12 and a charging interface 13 . The electric energy output by the solar panel 11 is converted by the charging module 12 and charged externally through the charging interface 13 . The terminal to be charged can be a mobile phone or a tablet computer, etc. For a terminal that supports fast charging, the charging interface 13 is required to provide it with a charging voltage higher than 5V, usually including multiple specifications such as 5V / 2A, 9V / 1.67A, 12V / 1.5A, etc. This requires the charging module 12 to be adjusted according to the situation.

Abstract

The invention provides a solar charging device and a charging method using a solar cell. The device includes a solar panel, a charging module, and a charging interface, and the charging module includes: a DC-DC converter, electrically connected to the solar panel and the charging interface, for converting the DC voltage output by the solar panel The DC voltage used for charging; the fast charging protocol identification module is electrically connected to the charging interface and the DC-DC converter to identify the charging command from the charging module and send it to the DC-DC converter to change the DC - the output voltage of the DC converter; and a load regulation module, electrically connected to the solar panel and the DC-DC converter, to stabilize the solar panel by adjusting the equivalent load of the solar panel output power, thereby improving the output efficiency of the solar panel.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to a solar charging device and a charging method using a solar battery. Background technique [0002] The solar charging device in the prior art is realized by using a solar cell plus a constant voltage module, wherein the constant voltage module outputs a fixed voltage, and the common form is an output capacity of 5V / 2A. With the rapid development of smart terminals, the battery capacity of products such as mobile phones is gradually increasing. In order to increase the charging speed, relevant manufacturers have proposed a fast charging method that changes the output voltage. The fast charging method needs the charging terminal to provide higher voltage, but there is no solar charging device supporting fast charging in the prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a solar charging device supporting fast ...
