Portable intelligent bionic thin film solar power supply unit

Abstract

The invention discloses a portable intelligent bionic solar power supply equipment mainly composed of an adjustable output voltage solar module group, two dc-dc conversion modules, a control unit, a bidirectional conduction switch circuit and a voltage adjustable battery. The portable intelligent bionic solar power supply equipment utilizes plant branch leaves bionics principle, dynamically adjusts each branch leaf angle according to the feedback information from each solar module group and stably outputs current by real time adjustment of the output voltage using a dynamic circuit. The equipment intelligently adjusts the series-parallel connection relationship of internal solar module group and built-in battery according to the output voltage requirement of a load, regulates the output voltage of each module near to the output voltage of the load, reduces the loss during the dc variable pressure process, improves the whole conversion efficiency to the maximum. The products are more portable and compact, the charging time is shorter, the efficiency is higher and the service life is longer.

Description

technical field [0001] The invention relates to the field of information electronics technology, in particular to a portable intelligent bionic thin-film solar power supply device. Background technique [0002] With the rapid development of the consumer electronics industry, the number of electronic devices around us, especially portable electronic devices, has increased significantly. Mobile electronic devices such as mobile phones, notebook computers, digital cameras, mp3, GPS, PMP, etc. all do not need to be powered by batteries to maintain normal work. At the same time, as the speed of processing chips continues to rise, the size of LCD screens continues to expand, and the wide application of wireless communication functions such as Bluetooth and Wi-Fi and other new technologies brings convenience to us and brings us further power consumption rises. However, current lithium-ion batteries, polymer batteries and nickel-metal hydride batteries generally have shortcomings ...

Problems solved by technology

At the same time, as the speed of processing chips continues to rise, the size of LCD screens continues to expand, and the wide application of wireless communication functions such as Bluetooth and Wi-Fi and other new technologies brings convenience to us and brings us Further power consumption rises

However, current lithium-ion batteries, polymer batteries and nickel-metal hydride batteries generally have shortcomings such as small capacity and slow charging.

The average standby time of a mobile phone is only 39 hours and the talk time is 2 hours after a single charge; the average use time of a notebook computer is less than 3 hours

[0004] At present, foreign portable thin-film solar power supply products can achieve short charging time and high performance such as portability, but their prices are also very high.

Although the price of domestic products is lower, their performance is poor and their practicability is not high.

Both domestic and foreign products are vulnerable to interference due to voltage and current stability problems, and the life of the charger is not long
