Photoelectric charger, charging method and its electronic products used thereof

Abstract

This invention relates to a photoelectric charger, a charging method and an electronic produc with it, in which, an electronic product with a charger includes a photoelectric charger, a host and a self-backup charge battery and the charger includes at least a photoelectric battery and an energy storager serial to the battery, the photoelectric battery charges to the energy storager, all energy storagers are connected with the self-backup batteries to charge to them, when charging, the photoelectric battery transfers light energy to electric energy and charges to the energy storager serial to it then the storager charges to the charge battery according to its voltage.

Description

technical field [0001] The invention relates to the field of electricity, in particular to the charging technology of photovoltaic cells in the field of electricity. Background technique [0002] With the development of science and technology, portable electronic products such as mobile phones, notebook computers, digital cameras, MP3, MP4, PDA (Personal Digital Assistant, Personal Digital Assistant) are becoming more and more popular, and the power supply problem of portable electronic products has gradually caused general concern. [0003] Since portable electronic products are usually small in size and light in weight, the power supply section is often more stringent in this regard. What is particularly important is that on the premise of ensuring the rich functional characteristics of portable electronic products, it is required that the power supply can provide higher and higher energy density and longer power supply time. [0004] At present, in the field of portable...

Problems solved by technology

[0011] However, both the plug-in type and the built-in type have certain limitations.

For example, the charging speed of the plug-in photoelectric charger is slow in rainy days and dark places, and the charging speed is fast in places with strong sunlight or bright places; and because the plug-in photoelectric charger is separated from portable electronic products, it is inconvenient to carry

However, if the built-in photoelectric charger is applied to high-performance portable electronic products with relatively large power consumption, it may not meet the demand due to the large power consumption; in addition, because the working characteristics of the two are just opposite, photoelectric chargers need Full sunlight means higher temperatures to work, and rechargeable batteries in portable electronics cannot function properly in an environment that is too hot

[0012] In addition, photoelectric chargers are also often used in various aspects of industry and daily life, such as automobiles. Because the applicable area of ​​automobiles is very large, such as the roof and the side of the car, photosensitive materials can be used to make photoelectric chargers. , but the photoelectric chargers currently applied to cars also have the problem of slow charging speed in rainy days and dark places, and the small power supply cannot meet the demand
