A power supply system and power supply method based on intelligent products

Abstract

The invention provides an intelligent product-based power supply system and a power supply method thereof. In the power supply system, an external power supply interface module supplies an external direct current power to the power supply system, and a mobile power supply module is charged by the external direct current power and then transmits the power to a power supply management module. The power supply management module powers up all function modules under the control of a main control module. At the same time, with the cooperation of the power supply management module, the main control module monitors and controls the running state of the mobile power supply module and the running state of a built-in battery module. The built-in battery module powers up the main control module. The built-in battery module also powers up all the other modules when the mobile power supply module cannot supply power normally. A sensing module acquires the sensing information and then transmits the sensing information to the main control module. The main control module judges whether to power up function modules or not according to the sensing information. The intelligent charging process of the built-in battery module is controlled by the main control module, so that the built-in battery module is always in the saturation condition. In this way, the power supply security of the system is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power supply system and a power supply method thereof. Background technique [0002] With the development of science and technology, smart products, such as mobile phones and tablet computers, have become indispensable partners in people's daily life, and the utilization rate of smart products is getting higher and higher, and even some smart products are available 24 hours a day. are in standby mode. [0003] However, existing smart products are generally powered by a rechargeable lithium battery. Obviously, with such a high utilization rate of smart products today, it is not possible to rely solely on lithium batteries for a single power supply in existing smart products. It satisfies people's requirements very well, and some people even have to charge their mobile phones several times a day, which brings a lot of inconvenience to people's daily life. [0004] In order ...

AI Technical Summary

Problems solved by technology

However, using a mobile power supply as a power supply system for smart products simply solves the temporary power supply problem, and the power in the mobile power supply is also limited, which cannot solve the long-term power supply problem of smart products; moreover, in some special scenarios For example, the mobile power supply must be taken out when going through security checks or air consignment, resulting in power failure of smart products, which is fatal to some real-time smart products that require constant charging; When supplying power to the functional modules, instead of stopping the power supply of temporarily unused modules and selecting the required modules according to the corresponding rules, it continues to supply power to all functional modules, which increases the power consumption of the system, wastes battery power, and shortens the battery power supply time.
