Technical Field
[0001] The utility model relates to a mobile power supply, specifically a mobile power supply with a large current charging port. Background Art
[0002] A mobile power supply, also known as a power bank, is a portable energy storage device. It has a battery cell inside to store electrical energy, a control circuit board for managing the charging and discharging of the mobile power supply, and charging and discharging interfaces, usually USB-A or type-c interfaces, which can be connected to electronic devices such as mobile phones to supply power to the mobile phones.
[0003] For existing mobile power supplies, a mobile phone charger is usually used to charge the mobile power supply, and the charging current is usually 2 - 3 amperes. For large-capacity mobile power supplies, such as those with a capacity of more than 30,000 milliampere-hours, the charging process will be very time-consuming. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is: to provide a mobile power supply whose charging port can support a larger charging current and can accelerate the charging speed.
[0005] The technical solution adopted by the utility model to solve its technical problem is:
[0006] A mobile power supply supporting large current charging includes a housing. A battery cell is arranged inside the housing for storing electrical energy. A charging port and a discharging port are exposed from the housing;
[0007] A control circuit is also arranged inside the housing. The charging port, the control circuit, and the battery cell are sequentially connected. After an external DC power supply is connected to the charging port, the control circuit converts the external DC power supply into an adapted DC power supply to charge the battery cell;
[0008] The battery cell, the control circuit, and the discharging port are sequentially connected. After an external device is connected to the discharging port, the control circuit converts the electrical energy of the battery cell into an adapted DC power supply to supply power to the external device;
[0009] The charging port is an XT30, XT60, or XT90 interface.
[0010] Furthermore, the housing is provided with a waterproof structure to prevent the inside of the housing from getting damp.
[0011] Furthermore, the housing is in the shape of a square plate. A protruding tubular opening is arranged on the side where the thickness of the housing is located. The charging port and the discharging port are located inside the tubular opening; a waterproof cover is also included. The waterproof cover is connected to the housing through a flexible component, and the waterproof cover detachably covers the tubular opening.
[0012] Furthermore, the discharging port is a USB-A interface or a type-c interface.
[0013] The beneficial effects of the present utility model are as follows: For the mobile power supply of this solution, its charging port adopts XT30, XT60 or XT90 interface. Compared with the traditional USB charging port, it can allow a larger charging current. Cooperating with a control circuit that supports large current, the mobile power supply can be quickly charged. Moreover, the XT30, XT60 or XT90 interface can meet the charging connection with the MPPT (maximum power point tracking) controller of solar energy, and a solar power supply device with a solar panel and an MPPT controller can be used to charge this mobile power supply, which is convenient for long-term outdoor use. Description of the Drawings
[0014] Figure 1 It is a three-dimensional schematic diagram of an embodiment of the mobile power supply of the present utility model, and the waterproof cover is omitted in the figure;
[0015] The reference numerals in the figure are: housing 1, tubular opening 2. Detailed Embodiments
[0016] The following further illustrates the present utility model in conjunction with the drawings and embodiments. Typically, it can be:
[0017] A mobile power supply that supports large current charging includes a housing 1. A battery core is arranged inside the housing 1 for storing electric energy. It also includes a charging port and a discharging port that are exposed from the housing 1;
[0018] A control circuit is also arranged inside the housing 1. The charging port, the control circuit and the battery core are sequentially connected. After an external DC power supply is connected to the charging port, the control circuit converts the external DC power supply into an adapted DC power supply to charge the battery core;
[0019] The battery core, the control circuit and the discharging port are sequentially connected. After an external device is connected to the discharging port, the control circuit converts the electric energy of the battery core into an adapted DC power supply to supply power to the external device;
[0020] The charging port is an XT30, XT60 or XT90 interface.
[0021] For the mobile power supply of this solution, a charging port that supports large current is set, enabling the mobile power supply to achieve large current charging, which is particularly suitable for large-capacity mobile power supplies.
[0022] Specifically, as Figure 1 shown, the same as the prior art, the mobile power supply of this solution also includes a housing 1. A battery core is arranged inside the housing 1 for storing electric energy. It also includes a charging port and a discharging port that are exposed from the housing 1, which are respectively used for charging devices and electrical equipment to access.
[0023] The control circuit is located inside the housing 1 and is used for the charging and discharging management and various controls of the mobile power supply.
[0024] The charging port, control circuit, and battery cell are connected in sequence. After an external DC power supply is connected to the charging port, the control circuit converts the external DC power supply into an adapted DC power supply to charge the battery cell. For example, after a 12V DC power supply from the outside is connected to the charging port, the control circuit converts it into a suitable voltage to charge the battery cell.
[0025] The battery cell, control circuit, and discharge port are connected in sequence. After an external device is connected to the discharge port, the control circuit converts the electrical energy of the battery cell into an adapted DC power supply to supply power to the external device. For example, after connecting the discharge port to a mobile phone with a charging cable, the control circuit converts the electrical energy of the battery cell into a suitable voltage to supply power to the mobile phone. A typical discharge port is a USB-A interface or a type-c interface.
[0026] To address the problem of slow charging speed of existing mobile power supplies, the mobile power supply of this solution has a charging port that is an XT30, XT60, or XT90 interface. XT30, XT60, or XT90 interfaces are usually used for the power supply socket of model airplanes and can support a larger charging current. For example, the rated current of the XT30 interface is 15A, and the rated current of the XT60 interface is 40A. This is greater than the rated current of traditional USB charging ports. Coupled with a control circuit that supports a large current, it can achieve fast charging of the mobile power supply.
[0027] In addition, with the above-configured charging port, the mobile power supply can be used for solar charging. Existing solar panels are usually connected to an MPPT (Maximum Power Point Tracking) controller, and its output current is greater than that of a mobile phone charger. The charging port of the mobile power supply in this solution can be connected to the output end of the MPPT controller, and rely on the large current output by the solar panel for fast charging, making the mobile power supply suitable for long-term use outdoors where there is a lack of mains power.
[0028] More preferably, the housing 1 can be provided with a waterproof structure to prevent the inside of the housing 1 from getting damp. For example, the waterproof structure can be a waterproof glue or a waterproof ring provided at the gap of the housing 1, which can prevent water vapor from entering and make the mobile power supply suitable for a humid outdoor environment.
[0029] More preferably, as Figure 1 shown, the housing 1 can have a square plate shape, and a protruding tubular opening 2 is provided on the side where the thickness of the housing 1 is located. The charging port and the discharge port are located inside the tubular opening 2; it also includes a waterproof cover, and the waterproof cover is connected to the housing 1 through a flexible component and can detachably cover the tubular opening 2.
[0030] The square plate shape of the housing 1 is convenient for carrying and also conducive to stable placement. The so-called square plate shape means that the outer shape is a cube shape, and the height of the cube is smaller than the length and width of the cube. For example, the height of the cube is smaller than half of the length of the cube, and the height of the cube is smaller than half of the width of the cube. For a cube in the shape of a square plate, its height is also called the thickness.
[0031] AsFigure 1 As shown, a protruding tubular opening 2 is provided on the side where the thickness of the housing 1 is located. The charging port and the discharging port are located inside the tubular opening 2, and the charging port and the discharging port are covered with a waterproof cover, which can prevent water vapor from entering through this.
[0032] The waterproof cover is connected to the housing 1 through a flexible component. When the mobile power supply is in use, the waterproof cover is opened to expose the charging port and the discharging port, so that wires can be connected. At other times, the tubular opening 2 is covered with the waterproof cover to prevent water vapor from entering the housing 1. The flexible component refers to a connecting component that is easily bent and deformed. Connecting the waterproof cover with a flexible component can facilitate operation. Common flexible components can be flexible thin ropes, thin rubber strips, etc.
