Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a full-matrix intelligent output integrated charging pile. Background Art

[0002] China's largest industrial consumption in the future will be new energy vehicles. Electric vehicles have become a powerful new engine to drive consumption and industrial upgrading. However, charging has become a shortcoming in industrial development, lagging significantly behind the development of electric vehicles. The construction of charging piles has become a prerequisite.

[0003] The small number of charging piles, slow charging, difficulty in finding piles, low utilization rate, mileage anxiety, safety anxiety, etc. have affected the user experience of pure electric vehicles to a certain extent, and have become a constraint and obstruction to the development of new energy vehicles. Therefore, it is necessary to vigorously promote the construction of charging piles.

[0004] Currently, the mainstream DC charging pile equipment on the market is an integrated dual-gun (also known as one-to-two) charging pile equipment. The power of the charging pile is generally between 30kW and 400kW, and the minimum granularity of its power distribution is half of the charging power. For example, a 300kW DC dual-gun charging pile composed of a single charging module with a power of 30kW, the minimum granularity of power that can be distributed by a single gun is 150kW, and the maximum output power is 300kW. If two vehicles are charging at the same time, the output power of each gun is 150kW.

[0005] Suppose two vehicles are charging at the same time, vehicle A requires 60kW of power and vehicle B requires 240kW of power. The charging pile cannot meet the demand and can only maintain 150kW output of each gun. This will cause unnecessary waste for vehicle A and increase the charging time for vehicle B, bringing a bad experience to customers and increasing operating costs for operators. Summary of the invention

[0006] In view of the problem that the power distribution of the above-mentioned existing integrated dual-gun DC charging pile is relatively fixed, the distribution granularity is too large, and it is not flexible enough, resulting in low charging pile utilization efficiency and high operating cost, the present invention is proposed.

[0007] Therefore, the purpose of the present invention is to provide a full-matrix intelligent output integrated charging pile, the purpose of which is to: adopt a new power distribution unit to make the power output granularity of each gun the power of a single module, and each gun can call any number of modules to improve the charging efficiency.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: a full-matrix intelligent output integrated charging pile, comprising a cabinet and a cabinet door on one side of one end of the cabinet, and also comprising a touch screen arranged at the top of one end of the cabinet door, a first charging gun arranged on one side of the cabinet, a second charging gun arranged on the side of the cabinet away from the first charging gun, multiple groups of air inlets arranged on one side of the cabinet, multiple groups of air outlets arranged on the side of the cabinet away from the air inlet, a first DC output component arranged on one side of one end of the cabinet inner cavity, a second DC output component arranged on the other side of one end of the cabinet inner cavity, a power distribution unit arranged at the top of one end of the cabinet inner cavity, and a DC charging module arranged at the bottom of one end of the cabinet inner cavity.

[0009] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, the first DC output component and the second DC output component are composed of a DC fuse, a shunt and a DC contactor.

[0010] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, wherein: the first charging gun and the first DC output component in the cabinet body cavity are interconnected, and the second charging gun and the second DC output component in the cabinet body cavity are interconnected.

[0011] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, the power distribution unit is composed of a high-power input terminal, a high-power connector, a program download terminal, a communication connection terminal, a power distribution board, a diode and a cooling fan.

[0012] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, wherein: the DC contactor is interconnected with the power distribution unit through a high-power connector, and the DC charging module is interconnected with the power distribution unit through a high-power input terminal.

[0013] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, a controller is provided in the inner cavity of the cabinet, and the communication connection terminal is connected to the controller.

[0014] As a preferred solution of the full-matrix intelligent output integrated charging pile described in the present invention, the power distribution board is composed of a first output terminal, a second output terminal, an input terminal, a relay and a chip.

[0015] The beneficial effects of the present invention are as follows: through the power distribution unit, according to the instructions of the controller, according to the power requirements of different vehicles, any number of modules are called, so that the power output granularity of the first charging gun or the second charging gun can be the power of a single module, and each charging module corresponds to a power distribution board, and each power distribution board can correspond to the first charging gun or the second charging gun. When multiple power distribution boards are aggregated, the high-power connector, the power distribution board and the high-power connector are directly connected to the diode, which can prevent the vehicle battery current from backflowing, so that the first charging gun and the second charging gun can intelligently distribute power. When two electric vehicles with different battery capacities or charging requirements are connected at the same time, the charging pile can automatically adjust the output power according to the specific situation of each vehicle to ensure that each vehicle can be charged at the optimal charging rate. By utilizing the reasonable distribution of power, the charging time of each electric vehicle can be effectively shortened, and at the same time, it can more effectively utilize electricity resources and reduce unnecessary waste, which helps to reduce the operating cost of the entire charging system, and may reduce the charging costs of users.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0034] Reference Figure 1-15 , an embodiment of the present invention provides a full-matrix intelligent output integrated charging pile, the full-matrix intelligent output integrated charging pile comprising a cabinet (1) and a cabinet door at one end of the cabinet (1), and also comprising a touch screen (2) arranged at the top of one end of the cabinet door, a first charging gun (3) arranged at one side of the cabinet (1), a second charging gun (4) arranged at a side of the cabinet (1) away from the first charging gun (3), a plurality of groups of air inlets (5) arranged at one side of the cabinet (1), a plurality of groups of air outlets (6) arranged at a side of the cabinet (1) away from the air inlet (5), a first DC output component (7) arranged at one side of an inner cavity of the cabinet (1), a second DC output component (8) arranged at the other side of an inner cavity of the cabinet (1), a power distribution unit (9) arranged at the top of one end of the inner cavity of the cabinet (1), and a DC charging module (10) arranged at the bottom of one end of the inner cavity of the cabinet (1).

[0035] The first DC output component (7) and the second DC output component (8) are composed of a DC fuse, a shunt and a DC contactor. The DC fuse is also called a fast fuse.

[0036] The first charging gun (3) and the first DC output component (7) in the inner cavity of the cabinet (1) are connected to each other, and the second charging gun (4) and the second DC output component (8) in the inner cavity of the cabinet (1) are connected to each other. The DC fuse is connected in series in the DC circuit. When the current in the circuit exceeds its rated value, it will quickly melt, thereby cutting off the circuit and protecting the circuit and equipment from damage caused by overload or short-circuit current. The DC fuse plays an important protective role in the circuit, effectively preventing excessive current from damaging the circuit or equipment, and ensuring the stable operation and safety of the power system. The shunt is a resistor used to measure voltage on the current, thereby indirectly measuring the current. It is made based on the principle that voltage is generated across a resistor when direct current passes through it. In addition, in the field of communications, a shunt also refers to a device that can divide an input signal into multiple output signals to achieve signal allocation and distribution. A DC contactor is an electrical switching device used to control the on and off of a DC circuit. A DC contactor refers to a contactor whose iron core is controlled by a DC coil. Its load can be either DC or AC. Its working principle is based on the electromagnetic attraction effect. When the contactor coil is energized, the coil current generates a magnetic field, causing the static iron core to generate electromagnetic attraction to attract the moving iron core, and drive the contacts to close or open the circuit.

[0037] The power distribution unit (9) is composed of a high-power input terminal (91), a high-power connector (92), a program download terminal (93), a communication connection terminal (94), a power distribution board (95), a diode (96) and a cooling fan (97).

[0038] The DC contactor is connected to the power distribution unit (9) via a high-power connector (92), and the DC charging module (10) is connected to the power distribution unit (9) via a high-power input terminal (91).

[0039] The cabinet (1) is provided with a controller in its inner cavity, and (13) is connected to the controller via a communication connection terminal (94).

[0040] The power distribution board (95) is composed of a first output terminal (951), a second output terminal (952), an input terminal (953), a relay (954) and a chip (955), and the high-power connector (92), the power distribution board (95) and the high-power connector (92) are directly connected to a diode (96) to prevent the vehicle battery current from flowing back.

[0041] During use, the power distribution unit (9) calls any number of modules according to the instructions of the controller and the power requirements of different vehicles, and charges the vehicle through the first charging gun (3) and the second charging gun (4), and each charging module corresponds to a power distribution board (95), and each power distribution board (95) can correspond to the first charging gun (3) or the second charging gun (4). When multiple power distribution boards (95) are combined, the high-power connector (92), the power distribution board (95) and the high-power connector (92) are directly connected to the diode (96), which can prevent the vehicle battery from backflowing current; Furthermore, the power output granularity of the first charging gun (3) or the second charging gun (4) can be made the power of a single module. For example, a 300kW integrated DC dual-gun charging pile composed of 15 30kW charging modules has a minimum power granularity of 30kW for each module, and each gun can call any number of modules.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
