Problems solved by technology

Such a charger is only used as a transmission medium between the power supply and the mobile phone. When people go out or there is no power supply indoors, people cannot help the mobile phone to charge in time, and they are highly dependent on the power supply. Affect the normal use of the mobile phone
[0003] At present, there is also a mobile charger, which fully charges the rechargeable battery when people have a power source. When people are outside or without a power source, the electric energy stored in the charger can be used to charge the mobile phone, but it is often used when going out or not. In the case of a power supply, it is also easy to consume power. Its internal storage of power is limited, and the power inside the charger cannot be replenished in time after the mobile phone is charged. Therefore, the charger cannot be recycled and reasonably utilizes the characteristics of the external environment. , unable to absorb the corresponding energy in the external environment by itself, therefore, the efficiency of this kind of charger is not high, resulting in the limitation of charging

Abstract

The invention discloses a solar charger for cell phones. The solar charger comprises a shell, a rechargeable battery, an output interface, a solar panel, sampling circuits, a power conversion circuit, an A/D (analog to digital) switching circuit, a single-chip microcomputer and a PWM (pulse-width modulation) control circuit, wherein the output interface is connected with the rechargeable battery, and the solar panel is located on the surface of the shell; the solar panel and the rechargeable battery are respectively connected to the A/D switching circuit through the sampling circuits; one end of the power conversion circuit is connected with the solar panel; the A/D switching circuit is connected with the single-chip microcomputer mutually; the other ends of the single-chip microcomputer and the power conversion circuit are respectively connected with the PWM control circuit connected with the rechargeable battery. Since the solar charger for the cell phones is movable, people can reasonably take advantages of surroundings when going out; solar energy can be converted into power to be stored in the rechargeable battery, so that energy conserving and recycling can be fully realized, use efficiency can be improved, and the solar charger is more convenient for the people to use.

Description

technical field [0001] The invention relates to a charger, in particular to a solar charger for mobile phones, and belongs to the technical field of solar energy applications. Background technique [0002] With the continuous development of communication technology, mobile phones have become an indispensable tool for people to communicate. Due to the portability and convenience of the mobile phone, it has been favored by people, and people have become accustomed to using mobile phones to communicate. Due to the small body of the mobile phone, the electric energy stored in the battery is limited, so the mobile phone needs to be used in conjunction with a charger. The traditional mobile phone charger includes a housing, a rechargeable battery, and an output interface arranged on the housing and connected to the rechargeable battery. The charger is connected to an external power source through its own plug. The mobile phone is connected to the output interface on the casing t...
