Mobile power source having wireless charging and discharging functions

Abstract

The invention relates to a mobile power source having wireless charging and discharging functions. The mobile power source comprises a coil unit used for carrying out magnetic field energy exchange with other equipment or components, an energy storage device used for storing energy provided by the coil unit or providing energy for the coil unit, and a charging and discharging control module, wherein one end of the charging and discharging control module is connected with the coil unit, the other end of the charging and discharging control module is respectively connected with a charging circuit and a discharging circuit, and the charging circuit and the discharging circuit are respectively connected with the energy storage device. Energy received by the coil unit can be received and processed by the charging and discharging control during charging, the processed energy is transmitted to the energy storage device through the charging circuit, the energy released by the energy storage device can be processed by the charging and discharging control module during discharging and then is released through the coil unit. Compared with the prior art, the coil unit can realize charging and discharging in a wireless induction mode, and a simple structure and low cost are realized.

Description

technical field [0001] The present invention relates to a mobile power supply, in particular to a mobile power supply with wireless charging and discharging. Background technique [0002] With the improvement of people's living standards, electronic products (such as mobile phones, flashlights, small fans, electric razors, table lamps, headlights, camping lights, etc.) have become indispensable for modern people. The frequency of use and the limitations of the place of use require frequent charging. In order to facilitate charging when going out, existing technical personnel have developed a mobile charging power supply. This mobile charging power supply contains a storage battery, which can Charge in the following ways: one is to directly connect the electronic product with the charging plug of the mobile charging power supply through the data cable, and the energy is stored in the battery of the electronic product from the charging plug; the second is to set the mobile cha...

AI Technical Summary

Problems solved by technology

Since the first type requires the use of a data cable to complete charging, one end of the data cable needs to be plugged into the electronic product every time it is charged, and then unplugged after charging is complete. This is not only troublesome, but also often leads to short wires and loose sockets The problem is that not only the charging effect is unstable, but also it will cause damage to the electronic product; the second type must put the electronic product in the charging stand, and must ensure that the charging end of the electronic product is connected to the discharging end of the charging stand. After a long time of use, the charging end of the electronic product and the discharge end of the charging stand will often be in poor contact due to misalignment, making the connection between the electronic product and the charging stand unstable.

On the other hand, for the above-mentioned mobile charging power supply for products such as emergency lights and camping lights, since such electronic appliances are often in a charging state when not in use, it is sometimes difficult for users to remove the product from the charging stand or charging power supply in time when in use. For this reason, prior art personnel have developed a kind of non-contact charging power supply

[0003] This type of non-contact charging power supply can charge the load by wireless induction through the electromagnetic induction of the coil unit, but when charging the battery in this type of non-contact charging power supply, it must be charged through the data line, the charging effect is unstable, and It will cause damage to electronic products, therefore, there is an urgent need for a non-contact charging power supply that can solve the above problems
