Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle charging, and in particular to a V2G charging pile, a fast charging energy storage machine and a charging system thereof. Background Art

[0002] The rapid increase in demand for oil resources and the serious negative impact on the environment caused by the development of the automobile industry have increasingly attracted people's attention. Governments, academia and industry around the world are increasing their investment in the development of electric vehicles to accelerate the commercialization of electric vehicles. V2G charging piles are charging piles that allow electric vehicles to transmit energy bidirectionally with the power grid. The concept is to use electric vehicles in a stopped state as mobile energy storage devices, which can absorb electricity from the power grid for charging, and can also feed back the stored electricity to the power grid when the power grid needs it, providing peak-shaving and frequency regulation, thereby enhancing the stability of the power grid. After the user scans the code on the charging pile to start the charging pile, he can choose to charge or send electricity as needed, and then take out the plug-in electric gun and insert it into the electric car. However, when the user puts the plug-in electric gun back, the connecting wire of the plug-in electric gun is too long and has a large diameter, which makes it difficult to put it back or entangled in surrounding objects, resulting in inconvenience in use, and even causing pedestrians to trip and cause personal injury. At the same time, the connecting wires hanging outside will easily be accidentally stepped on or crushed by vehicles, increasing the risk of wire damage, thereby affecting the normal operation of the charging equipment and even causing equipment damage.

[0003] The fast charging energy storage machine is an effective tool for on-board emergency charging and fast charging. It is an effective supplement to charging piles and charging stations. It can also be used to convert the 220-volt slow charging voltage into a 380-volt fast charging voltage to accelerate the charging speed. It is an ideal charging auxiliary tool for private electric vehicles. At present, fast charging energy storage machines generally have poor reliability. The connection circuit uses hard connection components, which leads to high stress at the connection part, which easily leads to loose connection and unreliable operation. At the same time, there are problems such as large size and inconvenience in movement. Summary of the invention

[0041] The present invention also provides a charging system for a fast-charging energy storage machine, including a filter, a temporary storage battery, a transformer, a rectifier and a control circuit. The filter, the transformer, the rectifier and the control circuit are all installed in the energy storage installation cavity, and the filter is electrically connected to two overload protection connectors 72 to filter the current input by the electric pile charging gun 30 and remove interference signals.

[0042] For example, in one embodiment: when it is necessary to remove the electric pile charging gun 30 to use the V2G charging pile for charging / discharging, the electric pile charging gun 30 is taken out of the gun slot 13, so that the gun holder card platform 25 is no longer subjected to the pressure of the electric pile charging gun 30, so that the pressure slide shaft 24 is driven by the rebound force of the inductive spring to move upward along the vertical strip slide groove 291, and send an electrical signal to the equal amount of rated energy storage device and the telescopic cylinder 27, so that the output shaft of the telescopic cylinder 27 retracts, so that the four second rotating mounting platforms 274 move inward synchronously, so that The lateral rotating rod 281 moves inward, so that the longitudinal rotating rod 282 moves along, so that the wire squeezing strip 283 moves along the outside, and the wire squeezing strip 283 moves toward the inner wall of the winding drum 21, so that the inner end of the wire squeezing strip 283 no longer abuts against the electric pile charging cable 31, and the winding tightness of the electric pile charging cable 31 decreases, so that the electric pile charging cable 31 can be quickly taken out, and at the same time, the equal-rated energy storage device will be started, and will output current / recover current to the electric pile charging cable 31 to complete charging / discharging.

[0043] When the charging / discharging is completed by using the V2G charging pile, the charging gun 30 of the charging pile is retracted into the gun slot 13, and the butt of the charging gun 30 of the charging pile is clamped on the butt clamping platform 25, so that the middle part of the charging line 31 of the charging pile will be close to the outer side of the charging pile shell 10 under the action of gravity / artificial push, and the pressure slide shaft 24 will slide downward along the vertical strip slide groove 291, so that the inductive spring is compressed, and an electrical signal is sent to the equal-amount rated energy storage device, the telescopic cylinder 27 and the rotating motor 26, so that the equal-amount rated energy storage device is disconnected and the charging / discharging is closed. At the same time, the output shaft of the telescopic cylinder 27 is extended, so that the four second rotating mounting platforms 274 move outward synchronously, so that the horizontal rotating rod 281 moves outward with it, and the longitudinal rotating rod 282 follows it. The wire squeezing strip 283 moves inward and along the wire squeezing groove 211 away from the inner wall of the wire reel 21, so that the inner end of the wire squeezing strip 283 squeezes the charging cable 31, so that the middle part of the charging cable 31 is squeezed and clamped between the inner end of the wire squeezing strip 283 and the outer side of the mounting plate 23. Subsequently, the output shaft of the rotating motor 26 rotates, so that the wire squeezing strip 283 rotates synchronously with the mounting plate 23, and then the charging cable 31 rotates synchronously, so that the bottom end of the loose charging cable 31 will be wound on the outer walls of the four wire squeezing strips 283, so that the charging cable 31 is wound, and the charging gun 30 is better clamped in the gun butt clamp 25 and the gun slot 13.

[0044] For example, in one embodiment: a paddle-type switch valve is arranged on the outside of the preset sliding hole, and when the electric pile charging gun 30 is not inserted into the power supply connection assembly 70, the outer end of the sliding column 633 is against the inner side of the paddle-type switch valve, and at this time, the mid-vertical direction of the installation clamp block 751 is arranged parallel to the horizontal direction of the mobile energy storage box 40.

[0045] For example, in one embodiment: when it is necessary to use a fast charging energy storage machine for voltage conversion, the electric pile charging gun 30 is inserted into the plug-in gun barrel 732, and the multiple conductive posts inside the electric pile charging gun 30 are inserted into the connecting head 733. When the electric pile charging gun 30 is inserted inward, the connecting head 733 will slide inward along the inner wall of the connecting mounting barrel 731. Since the outer diameter of the inner wall of the connecting mounting barrel 731 gradually decreases from the outside to the inside, the outer wall of the annular V-shaped spring 734 will gradually fit the connecting mounting barrel 731, and then the connecting head 733 will gradually be tightened and clamped in the connecting mounting barrel 731. At the same time, the rotating compression spring 746 is compressed. Since the inner end of the rotating compression spring 746 is fixedly connected to the limit block 740, and the outer side of the inner rotating barrel 742 is rotatably installed on the inner outer edge of the connecting head 733, when the rotating When the compression spring 746 is compressed, it will drive the inner rotating cylinder 742 to move inward along with the rotation, thereby causing the two electrode arc pieces 744 to move inward along with it, until the inner sides of the two electrode arc pieces 744 are respectively attached to the outer sides of the two connecting electrode pieces 721, and then the current of the pile charging gun 30 is transmitted to the two overload protection connectors 72 in sequence through the connecting head 733, the connecting electrical block 737, the electrical connecting column 745, the two stable conductive pieces 749, the two electrode arc pieces 744 and the two connecting electrode pieces 721, and then the subsequent electrical transmission is carried out through the two overload protection connectors 72.At the same time, when the inner rotating cylinder 742 rotates and moves inward, the pushing arc piece 743 will move synchronously, so that the pushing arc piece 743 will push the connecting arc block 747 to rotate along the sliding preset groove 735, thereby making the rotating buckle ring 741 and the installation clamping block 751 rotate along the inner side of the outer wall of the connecting installation cylinder 731, so that the installation clamping block 751, which was originally set in the horizontal direction of the mid-perpendicular direction parallel to the mobile energy storage box 40, gradually rotates in the vertical direction. During the process, the inner side of the installation clamping block 751 will push and open the paddle type switch valve, so that the outer end of the sliding column 633 slides outward under the action of the compression spring 634, and is held on the inner side of the installation clamping block 751, and rotates with the installation clamping block 751. When the mid-perpendicular direction of the installation clamping block 751 is parallel to the vertical direction, the sliding column 633 will slide further outward until the outer side of the sliding column 633 is The end is held against the inner side of the sliding button, thereby locking and positioning the rotating buckle 741 and the installation card block 751, and at this time, the electric gun buckle will be locked in the installation slot 752, so that the electric gun buckle of the electric pile charging gun 30 is locked in the rotating buckle 741 and the installation card block 751, and the inside of the electric pile charging gun 30 is locked in the connecting installation tube 731, thereby completing the installation and connection of the electric pile charging gun 30, and through multi-point connection, the stability of the connection of the electric pile charging gun 30 is guaranteed, and the current of the electric pile charging gun 30 during the power transmission process is guaranteed to be transmitted to the two overload protection connectors 72 in sequence through the connecting head 733, the connecting electrical block 737, the electrical connection column 745, the two stable conductive sheets 749, the two electrode arc sheets 744 and the two connecting electrode sheets 721, and then the subsequent power transmission is carried out through the two overload protection connectors 72, thereby ensuring the stability of this power transmission circuit.

[0046] When the sliding column 633 slides outward under the action of the compression spring 634, the driven horizontal bar 632 will follow the movement, and the two sliding vertical bars 631 will follow the movement, and the triangular extrusion block 635 will follow the movement, squeezing the trapezoidal bar 624 downward, causing the elastic compression block 623 to deform and unload the force, preventing the compression spring 634 from having too much elastic force, causing the connection part to prevent vibration and affect the electrical connection. At the same time, the stabilizing mounting frame 62 generates an inward extrusion stabilizing force to ensure the stability of the power supply connection assembly 70 inside the stabilizing mounting frame 62 during charging.
