Intelligent functional and portable power supply and control method thereof

Abstract

The present invention discloses an intelligent functional and portable power supply and a control method thereof. An alternating current network connection is connection of a two-way converter and a first two-way DC / DC converter, the first two-way DC / DC converter module is connected with a second two-way DC / DC converter, a solar cell panel is connected with a two-way converter and a first two-wayDC / DC converter, a flexible thin film solar panel and a storage battery are connected with the first two-way DC / DC converter and the second two-way DC / DC converter, and the second two-way DC / DC converter is connected with an energy storage battery. The intelligent functional and portable power supply and the control method thereof can effectively utilize the solar energy clean energy, can achievedigital intelligent control, can perform modularized design to allow functions of products to be richer, and can meet the energy supply demands of a plurality of voltage-level electrifying devices; and moreover, products are high in universality in various occasions, have standard interfaces, are high in intelligent degree, can be rapidly input to markets for usage, and have overvoltage protection, overcurrent and short-circuit protection to allow the products to be safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an intelligent multifunctional portable power supply and a control method thereof. Background technique [0002] With the continuous development of the global economy and the continuous growth of the world population, human beings are increasingly inseparable from electric energy. But now with the rapid development of science and technology and the advent of many products, human beings are faced with many power supply problems: (1) The demand for electric energy continues to grow, and with the continuous consumption of traditional fossil energy coal, oil, and natural gas, And they are non-renewable, it is impossible for them to meet all our power supply needs; (2) The development of science and technology has produced many electronic products, such as smart phones, notebook computers, tablet computers, and digital cameras, etc. Digital electronic products, these e...

Problems solved by technology

But now with the rapid development of science and technology and the advent of many products, human beings are faced with many power supply problems: (1) The demand for electric energy continues to grow, and with the continuous consumption of traditional fossil energy coal, oil, and natural gas, And they are non-renewable, it is impossible for them to meet all our power supply needs; (2) The development of science and technology has produced many electronic products, such as smart phones, notebook computers, tablet computers, and digital cameras, etc. Digital electronic products, these electronic products have little battery energy storage, but they are used frequently and consume electricity quickly, and there is an urgent need to solve their charging and supply problems; (3) The popularity of electric scooters, especially the number of electric vehicles in the household and logistics fields (4) Human activities are increasing in areas without power grids (field adventures, travel, etc.), and some of their daily electricity needs must also be met; ( 5) With the acceleration of urbanization, the accelerated development of smart homes, the rapid development of smart cities, and the popularity of electric vehicles, there is an urgent need for a convenient and fast charging and power supply method to meet the power supply demand

[0004] 1. If figure 1 As shown, this portable power supply only charges the storage battery through the grid, and then uses the storage battery to supply power to some specific devices in some occasions, so it has many obvious disadvantages: (1) the energy source is single (only through the storage of the storage battery) (2) The power supply equipment will be disturbed by the external environment and cannot continue to supply power; (3) It cannot provide power supply requirements for various voltage types of electrical equipment; (4) When it is outside During long-term outdoor activities such as self-driving tours and field adventures, it cannot meet the long-term power supply demand, cannot fully cope with the harsh outdoor conditions, and the application occasions are limited; (5) It cannot carry out two-way energy flow, and the excess energy can be fed back to the grid. cause waste of energy

[0005] 2. If figure 2 As shown, the portable power supply designed by using solar energy also has many disadvantages: (1) it has relatively high requirements on the environment; (2) its power conversion efficiency is extremely low; (3) although there is a battery for energy storage, its energy Also can not satisfy the power supply for a long time; (5) when storage battery is fully charged, solar energy just can't be utilized again, causes the waste to solar energy
