Mobile power supply, charging and discharging system, and charging and discharging method of charging and discharging system

Abstract

The invention provides a mobile power supply which comprises an electric core, a control circuit, a charging circuit, a discharging circuit, a charging port used for connecting an adapter and a discharging port used for connecting electronic equipment. The mobile power supply further comprises a first switch and a second switch, and is characterized in that the charging port is sequentially connected with the first switch and the second switch in series and is connected with the discharging port, the charging circuit and the discharging circuit are connected with the electric core, the charging circuit and the discharging circuit are electrically connected to a connecting node between the first switch and the second switch, the control circuit is electrically connected with the charging port, the discharging port, the first switch, the second switch, the charging circuit and the discharging circuit, and the control circuit controls the mobile power supply to operate at different operating mode through detecting the connecting state of the charging port and the discharging port. The invention further provides a charging and discharging method of the charging and discharging system. The mobile power supply and the charging and discharging method of the charging and discharging system provided by the invention not only can meet charging requirements of users, but also can ensure the charging efficiency and the like.

Description

【Technical field】 [0001] The invention relates to the field of charge and discharge, in particular to a mobile power supply, a charge and discharge system, and a charge and discharge method for the charge and discharge system. 【Background technique】 [0002] Users often connect one end of the adapter to the mains and the other end to the electronic device to charge the electronic device through the mains power; or connect the computer and the electronic device through a data cable, and charge the electronic device through the computer in the power-on state. However, the user cannot obtain power from the mains or the computer anytime and anywhere to supply electronic equipment, such as when the user is doing outdoor activities. Therefore, the application of mobile power is born. The mobile power supply is small in size and easy to carry. Users can provide power to electronic devices anytime and anywhere through the mobile power supply. However, we usually encounter the situa...

Problems solved by technology

However, we usually encounter the situation that both the mobile power supply and the electronic device are in urgent need of charging. When there is only one mains socket, the user can only choose to charge the electronic device or the mobile power supply, which is difficult to meet the urgent charging needs of the user. need

In the case that the user has multiple mains sockets but only one adapter, the user can only charge one of the electronic equipment or the mobile power supply. Of course, the user can also charge the mobile power supply through the mains power supply. The electronic equipment is powered, and the power obtained by the mobile power supply is immediately supplied to the electronic equipment. In this way, the simultaneous charging of the electronic equipment and the mobile power supply can be realized, but in this way, the charging efficiency of the electronic equipment and the mobile power supply as a whole will not be improved at all. to upgrade, so it is urgent to propose new solutions to solve the charging needs in these cases
