A mobile power bank with intelligent control of solar charging and digital display

Abstract

The invention discloses a portable power source capable of intelligently controlling solar battery charging and digital display. The portable power source comprises a solar battery charging module, a portable power source module and a display module. The solar battery charging module charges the portable power source module by converting luminous energy to electric energy; the portable power source module is provided with an electricity meter integrated circuit and acquires electric quantity information of the portable power source module and charging information of the solar battery charging module; and the display module is provided with a liquid crystal display screen and displays the electric quantity information and the charging information. The portable power source capable of intelligently controlling the solar battery charging and the digital display can real-timely and conveniently display the charging information and the surplus electric quantity, and the relationship between intensity of illumination and charging current, and can intelligently control charging states of the portable solar battery; and besides, according to the portable power source with the solar energy adopted for charging, charging and discharging are combined, and therefore compared with a portable power source with a charging device separately arranged, size is diminished, electronic waste is reduced, low carbon and environment protection can be achieved due to the fact that solar energy is adopted for charging, a user can freely charge portable power sources and digital equipment at any time in indoor or outdoor places (so long as light exists), and therefore the portable power source can bring convenience to daily trips.

Description

technical field [0001] The present invention relates to a mobile power supply, in particular to a mobile power supply with intelligent control of solar charging and digital display. Background technique [0002] Mobile power is a portable charger that integrates power supply and charging functions, which can charge mobile phones and other digital devices anytime, anywhere or standby power. Because the voltage of the commonly used lithium battery is between 2.7-4.2V, the power will drop as the voltage drops. The voltage of 2.7-4.2V cannot directly charge other digital products, because the lithium battery voltage of digital products is also 2.7-4.2V, and the voltage of the same potential cannot be charged, so it is necessary for the mobile power supply to output electric energy. There must be a booster system. [0003] However, boosting the 2.7-4.2V lithium battery voltage to 5V will cause a certain loss. The existing technology uses resistance and capacitance for detection...

AI Technical Summary

Problems solved by technology

[0003] However, boosting the 2.7-4.2V lithium battery voltage to 5V will cause a certain loss. The existing technology uses resistance and capacitance for detection. In use, the battery capacity error is very large, and the voltage and current of charging and discharging cannot be seen intuitively. Therefore, the power indicator displayed by the LED light brings great inconvenience to the user.

[0004] Moreover, the so-called solar mobile power supplies on the market are still very inconvenient for users to use, including the inability to obtain power information and charging information in real time, and the dual-output charging method cannot automatically distribute power, etc.
