[0025] In order to facilitate understanding by those skilled in the art, the present invention will be further described in detail below in conjunction with specific embodiments.

[0026] The utility model provides a charging terminal based on full-automatic charging, such as Figure 1 As shown, including:

[0027] A charging gun holder 10 and a charging gun 20, wherein the charging gun holder 10 and the charging gun 20 are connected via a power supply line, and the charging gun holder 10 and the charging gun 20 do not have an AC-to-DC charging power module;

[0028] The charging gun holder 10 includes a fast charging interface 30, a switch module 40, a display module 50 and a main control module 60;

[0029] The fast charging interface 30 is used to connect to the fast charging interface 30 of the charging cabin to provide the charging gun 20 with vehicle charging current;

[0030] The switch module 40 is connected in series in the power supply line. The switch module 40 includes a circuit breaker and an emergency stop switch. The circuit breaker is connected in series with the emergency stop switch. The circuit breaker is used to switch the power supply line on and off according to the charging interruption instruction;

[0031] The display module 50 is used to display the display information sent by the main control module 60;

[0032] The main control module 60 is used to send a charging interruption instruction to the circuit breaker, so that the power supply line is physically disconnected and connected;

[0033] The display module 50 and the circuit breaker are both connected to the main control module 60 .

[0034] Specifically, in this embodiment, the position of the charging gun holder 10 includes: being set on the wall, ground or parking lot pillar inside the parking space; or being set on the parking lot pillar, wall or ground near the electric vehicle passage of the parking lot; or being set in the middle of multiple parking spaces so that one charging gun holder 10 serves multiple parking spaces; or setting a charging gun holder 10 next to a parking space for exclusive charging.

[0035] Each of the charging gun holders 10 corresponds to one or more charging guns 20 . When there are multiple charging guns 20 , only one charging gun 20 can be powered at the same time.

[0036] When a charging gun holder 10 corresponds to multiple parking spaces, and an electric vehicle in one parking space is being charged with a charging gun 20, other electric vehicles cannot be charged. The driver of the next electric vehicle can only insert the charging gun 20 into the charging port of the next electric vehicle after the corresponding charging gun 20 is put back into the charging gun holder 10 after the corresponding charging gun 20 is finished working. During this process, the driver of the next electric vehicle either waits in place or looks for other free parking spaces where the corresponding charging gun 20 is not occupied, but both waste extra time. When each charging gun holder 10 has multiple charging guns 20, the driver of the next electric vehicle can directly insert the second charging gun 20 into the charging port of the next electric vehicle. Although the charging gun 20 cannot charge the electric vehicle immediately, the driver of the next electric vehicle can leave after inserting the charging gun 20. After the previous charging gun 20 is charged, the driver can immediately switch to supply energy to the second charging gun 20 to charge the charging port of the next electric vehicle.

[0037] When there are multiple charging guns 20 , there are correspondingly multiple switch modules 40 for controlling each charging gun 20 respectively.

[0038] In this embodiment, the charging gun holder 10 is only electrically connected to the corresponding charging cabin, and is not directly electrically connected to the external power grid. The charging cabin outputs direct current to the charging terminal, and the charging gun 20 outputs direct current to the electric vehicle.

[0039] The distance between the charging gun seat 10 and the corresponding charging cabin is generally only a few meters or at most a dozen meters. It only requires laying cables for a distance of a dozen meters, and the charging cabin supplies power to the charging gun seat. In the prior art, the power supply of the charging pile needs to be connected from a distant distribution room to provide a large current for the charging gun 20 for charging. When the parking lot is large, a large number of dedicated wires are required. The use of this solution can save a lot of subsequent wiring costs.

[0040] The charging piles in the prior art are generally directly connected to the power distribution room to provide a high-current charging power supply, but the power distribution room is AC, so each charging pile needs an AC-to-DC charging power module. The charging power modules currently applicable to charging piles are expensive, often reaching several thousand yuan each, resulting in the inability to reduce the cost of charging piles and the cost of deploying a large number of charging piles in the entire parking lot. In this embodiment, since the charging gun holder 10 is only electrically connected to the corresponding charging cabin and powered by the charging cabin, and the charging cabin is also directly charged by DC by the charging robot, the charging gun holder 10 and the corresponding charging cabin do not need a built-in AC-to-DC charging power module. When a large number of charging gun holders 10 and charging cabins need to be deployed in the entire parking lot, the cost will be greatly reduced compared to the charging pile solution of the prior art.

[0041] In this embodiment, the charging gun 20 or the charging gun holder 10 is provided with a QR code corresponding to the charging terminal. After the charging gun 20 corresponding to the charging gun holder 10 is inserted into the charging port of the electric vehicle, the vehicle information of the electric vehicle is automatically obtained by scanning the QR code on the charging gun 20 to activate the charging instruction of the vehicle.

[0042] When the user inserts the charging gun 20 into the charging port of the electric vehicle, the charging instruction of the vehicle can be wirelessly activated by scanning the QR code with a mobile phone and performing corresponding operations.

[0043] In this embodiment, the display module 50 is an LED display panel, which is used to indicate the working status of the charging gun. The working status of the charging gun includes idle, abnormal fault, successful connection, and charging.

[0044] In other embodiments, the display module is an indicator light.

[0045] In this embodiment, the LED display panel displays a QR code corresponding to the charging terminal.

[0046] In this embodiment, the circuit breaker and the emergency stop switch are in a normally closed state.

[0047] When the switch module 40 obtains the instruction to interrupt charging, the circuit breaker is disconnected, so that the power supply line is disconnected and charging is stopped.

[0048] When the user needs to stop charging, the emergency stop switch is turned off to disconnect the power supply line and stop charging.

[0049] In this embodiment, a communication module is also included, and the communication module is connected to the main control module 60 and is used to communicate with the charging cabin and the server.

[0050] In this embodiment, the communication module of the charging terminal communicates with the charging cabin via a CAN bus.

[0051] In other embodiments, the communication module is wireless communication, and the communication module is one of Wifi, Bluetooth, and 5G modules, so that the wireless communication connection can be achieved via a Wifi, Bluetooth, or 5G wireless communication network.

[0052] This embodiment also provides a fully automatic charging system, such as Figure 1-2 As shown, including:

[0053] The charging cabin 200 and the above-mentioned charging terminal 100 based on fully automatic charging;

[0054] The charging terminal 100 includes a charging gun holder 10 and a charging gun 20, wherein the charging gun holder 10 is connected to the charging gun 20 through a power supply line, and the charging gun holder 10 and the charging gun 20 do not have an AC-to-DC charging power module; the charging gun holder 10 includes a fast charging interface, a switch module, a display module and a main control module; the fast charging interface is used to connect to the fast charging interface of the charging cabin to provide the charging gun 20 with vehicle charging current; the switch module, the switch module is connected in series in the power supply line, the switch module includes a circuit breaker and an emergency stop switch, the circuit breaker is connected in series with the emergency stop switch, and the circuit breaker is used to open and close the power supply line according to the acquisition of the interrupt charging instruction; the display module is used to display the display information issued by the main control module; the main control module is used to issue an interrupt charging instruction to the circuit breaker, so that the power supply line is physically disconnected and connected; the display module and the circuit breaker are both connected to the main control module;

[0055] A charging cabin 200, wherein the charging cabin 200 and the corresponding charging gun holder 10 are structurally separated but electrically connected, the charging cabin 200 is close to the electric vehicle passage, and the charging cabin 200 has a first automatic charging docking mechanism;

[0056] A charging robot 300, wherein the charging robot 300 includes an energy storage system, a charging system, an automatic driving control system, and a second automatic charging docking mechanism, and the charging robot does not have a charging gun 20;

[0057] A charging robot mother cabin, wherein the charging robot mother cabin has a third automatic charging docking mechanism for charging the charging robot;

[0058] When the charging gun 20 corresponding to the charging gun holder 10 is inserted into the charging port of the electric vehicle, in response to the user's vehicle charging instruction, the first information of the corresponding electric vehicle and the second information of the corresponding charging gun 20 are obtained; the third information of the charging cabin is obtained according to the second information of the charging gun 20; according to the first information of the electric vehicle and the third information of the charging cabin, a suitable charging robot is called to move to the corresponding charging cabin position, the charging robot and the charging cabin are docked for charging, and the electric vehicle is charged through the charging cabin and the corresponding charging gun 20.

[0059] Specifically, the charging gun holder 10 and the charging cabin 200 in this embodiment are separately arranged, wherein the charging cabin 200 is arranged near the electric vehicle passage, for example, on a parking lot pillar 400 near the electric vehicle passage of the parking lot, or near the wall of the electric vehicle passage of the parking lot, or is separately arranged next to the electric vehicle passage of the parking lot, wherein the first automatic charging docking mechanism of the charging cabin 200 faces the electric vehicle passage.

[0060] The position of the charging gun holder 10 can be flexibly set. It can be set in the middle of multiple parking spaces so that one charging gun holder 10 serves multiple parking spaces. A charging gun holder 10 can also be set next to a parking space for exclusive charging. The charging gun holder 10 can be located on the wall, ground or parking lot column 400 inside the parking space, or on a parking lot column 400, wall or ground near the electric vehicle passage in the parking lot.

[0061] The charging gun holder 10 and the charging cabin 200 of this embodiment are separately arranged. Since the charging cabin 200 is arranged near the electric vehicle passage, it is convenient for the charging robot to move to the charging cabin 200 for charging and docking. The position of the charging gun holder 10 can be flexibly set, and the charging robot does not need to move to the charging port of the electric vehicle to charge, thereby effectively utilizing existing parking lot resources and reducing the construction process of charging facilities.

[0062] In this embodiment, the charging gun holder 10 is only electrically connected to the corresponding charging cabin, and is not directly electrically connected to the external power grid. The charging gun holder 10 in this embodiment is generally only a few meters away from the corresponding charging cabin at most a dozen meters, and only a dozen meters of wiring is needed, and the charging cabin is powered; in the prior art, the power supply of the charging pile needs to be connected from a very distant distribution room to provide a large current for the charging gun 20 for charging. When the parking lot is large, a large number of dedicated wires are required. Using this solution can save a lot of later wiring costs.

[0063] The charging piles in the prior art are generally directly connected to the power distribution room to provide a high-current charging power supply, but the power in the power distribution room is AC, so each charging pile needs an AC-to-DC charging power module. The charging power modules currently applicable to charging piles are expensive, often reaching several thousand yuan each, resulting in the inability to reduce the cost of charging piles and the cost of deploying a large number of charging piles in the entire parking lot. In this embodiment, since the charging gun holder 10 is only electrically connected to the corresponding charging cabin and powered by the charging cabin, and the charging cabin is also directly charged by DC by the charging robot, the charging gun holder 10 and the corresponding charging cabin of this solution do not need to have a built-in AC-to-DC charging power module. When a large number of charging gun holders 10 and charging cabins are deployed in the entire parking lot, the cost will be greatly reduced compared to the charging pile solution of the prior art.

[0064] In this embodiment, each charging gun holder 10 has one or more charging guns 20. When there are multiple charging guns 20, only one charging gun 20 can be powered at the same time. Since this solution uses a charging robot to charge electric vehicles, the power of the energy storage system carried by the charging robot itself is limited, so generally one charging robot charges one electric vehicle with one charging gun 20.

[0065] In other embodiments, when a charging gun seat corresponds to multiple parking spaces, and an electric vehicle in one parking space is being charged with a charging gun 20, other electric vehicles cannot be charged. The driver of the next electric vehicle can only insert the charging gun 20 into the charging port of the next electric vehicle after the corresponding charging gun 20 is completed and returned to the charging gun seat. During this process, the driver of the next electric vehicle either waits in place or looks for other idle parking spaces where the corresponding charging gun 20 is not occupied, but both waste extra time. When each charging gun seat has multiple charging guns 20, the driver of the next electric vehicle can directly insert the second charging gun 20 into the charging port of the next electric vehicle. Although the charging gun 20 cannot charge the electric vehicle immediately, the driver of the next electric vehicle can leave after inserting the charging gun 20. After the previous charging gun 20 is fully charged, the driver can immediately switch to powering the second charging gun 20 to charge the charging port of the next electric vehicle.

[0066] In this embodiment, the charging robot 300 includes an energy storage system, a charging system, an automatic driving control system, a vehicle base, and a second automatic charging docking mechanism, and the charging robot does not have a charging gun 20. The charging robot 300 has a second automatic charging docking mechanism, which can be docked with the first automatic charging docking mechanism of the charging cabin for DC charging; the second automatic charging docking mechanism can also be docked with the third automatic charging docking mechanism of the charging robot mother cabin, so that the charging robot mother cabin can charge the charging robot.

[0067] And because the charging robot of this solution docks the charging cabin and the charging robot mother cabin through the second automatic charging docking mechanism, the charging gun 20 is not needed, saving hardware costs. And because the charging robot does not have a charging gun 20, the driver of the electric car does not need to wait for the charging robot to reach the charging position to plug and unplug the gun as in the prior art. The driver of the electric car of this patent directly inserts the charging gun 20 of the charging gun holder 10 next to the parking space into the electric car, saving the driver's time. Compared with other prior arts that use automatic mechanical arms to complete the automatic plug and unplug of the charging gun 20, this application can greatly reduce the cost of the charging robot.

[0068] In other embodiments, when the local power grid corresponding to the parking lot is out of power, a charging robot can also be used to provide emergency power to the local power grid through the charging robot mother cabin.

[0069] Finally, it should be noted that any modification or equivalent replacement of part or all of the technical features based on the device structure of the utility model and the technical solution of the described embodiment, which does not deviate from the essence of the corresponding technical solution of the utility model, belongs to the patent scope of the device structure of the utility model and the described implementation scheme.
