TECHNICAL FIELD

[0001] The present application relates to the field of new energy vehicle charging infrastructure, in particular to an intelligent identification device for abnormal charging behavior in vehicle-network interaction. BACKGROUND

[0002] With the explosive growth of the new energy vehicle industry, the demand for charging piles as the "energy portal" of new energy vehicles is also growing, so charging piles are gradually installed in parking locations such as parking lots and community ground floors. The charging lines of existing charging piles are directly placed on the ground. If someone passes by when the charging pile is idle, the charging line on the ground is easy to trip the elderly or children. At the same time, the physical structure of the charging line is severely damaged by the long-term trampling of pedestrians, greatly reducing the service life of the charging line and further increasing the maintenance cost of the charging pile.

[0007] Preferably, a barrier filter plate corresponding to the liquid-cooled radiator is provided on one side of the main housing through a rectangular through hole, an air exchange frame is provided between the barrier filter plate and the liquid-cooled radiator, and a shielding plate is provided on the top of the main housing.

[0012] (3) Beneficial effects 1. After the charging gun is removed from the placement frame using the cable retraction device, the user turns on the motor via the operating switch. The motor drives the rotating gear to rotate clockwise through the output shaft. The rotating gear drives the first rotating drum to rotate clockwise through its teeth. The first rotating drum drives the rotating disk, winding column, upper baffle, and second rotating drum on its upper side to rotate clockwise. The winding column unwinds the charging cable. As the winding column unwinds the cable, when the charging cable is retracted after charging is complete, the motor drives the rotating gear to rotate counterclockwise through the output shaft. The rotating gear drives the first rotating drum to rotate counterclockwise through its teeth. The first rotating drum drives the rotating disk, winding column, upper baffle, and second rotating drum on its upper side to rotate counterclockwise. The winding column rotates counterclockwise to retract the charging cable, further storing the charging cable inside the main housing. This prevents the charging cable from being exposed on the ground when the charging station is not in use, avoids the charging cable tripping over the elderly or children, and prevents prolonged trampling by pedestrians from severely damaging the physical structure of the charging cable, greatly extending the service life of the charging cable.

[0013] 2. The winding post is U-shaped and hollow, and the charging cable is wound on the winding post. The outer side of the wound U-shaped hollow post has multiple rounded corners, which avoids damage to the internal physical structure of the charging cable due to excessive angle in the outer area when the charging cable is wound and bent, thereby further increasing the service life of the charging cable.

[0014] 3. The placement component includes a placement frame on the assembly box. The placement frame has a fixing shell inside, and the fixing shell has a spring and a limiting block inside. The spring releases elastic potential energy upward to push the limiting block to limit the installation of the charging gun, and further places the charging gun in the placement frame.

[0020] A smart device for identifying abnormal charging behavior in vehicle-to-grid interaction, such as Figures 1-8 As shown, it includes a main housing 1. Inside the main housing 1, from bottom to top, there are a first mounting plate 103, a second mounting plate 104, and a third mounting plate 105. The first mounting plate 103 is provided with a working component assembly 2. The second mounting plate 104 is provided with a cable winding device 3 for storing the charging cable 310. The main housing 1 is provided with a placement assembly 4 for storing the charging gun 311. The winding device 3 includes a motor 301, which is mounted inside the main housing 1 via a mounting base and a support plate. The motor 301 has a rotating gear 302 via an output shaft. Between the second mounting plate 104 and the third mounting plate, from bottom to top, are arranged a first rotating drum 303, a rotating disk 304, a winding column 305, an upper baffle 306, and a second rotating drum 307. The first rotating drum 303 has a ring of teeth on its outer side, and the first rotating drum 303 is connected to the rotating gear 302 through the teeth. The first rotating drum 303 and the second rotating drum 307 are rotatably connected to the second mounting plate 104 and the third mounting plate 105, respectively. Inside the first rotating drum 303 and the second rotating drum 307, a first wire guide 308 and a second wire guide 309 are respectively provided through a limiting ring. The first wire guide 308 and the second wire guide 309 can guide the charging cable 310 and its wires, preventing the charging cable 310 from getting tangled with other wires when the winding column 305 rotates. The winding column 305 is U-shaped and hollow, and a charging cable 310 is wound around it. The other end of the charging cable 310 is connected to a charging gun 311. The charging gun 311 is equipped with an operation switch. After the charging gun 311 is removed from the placement frame 401, the user turns on the motor 301 through the operation switch. The motor 301 drives the rotating gear 302 to rotate clockwise through the output shaft. The rotating gear 302 drives the first rotating drum 303 to rotate clockwise through its teeth. The first rotating drum 303 drives the rotating disk 304, the winding column 305, and the upper baffle 306 on its upper side. The second rotating drum 307 rotates clockwise, and the winding column 305 unwinds the charging cable 310 on it. As the winding column 305 unwinds the cable, when the charging cable 210 is wound up after charging is completed, the motor 301 drives the rotating gear 302 to rotate counterclockwise through the output shaft. The rotating gear 302 drives the first rotating drum 303 to rotate counterclockwise through its teeth. The first rotating drum 303 drives the rotating disk 304, winding column 305, upper baffle 306 and second rotating drum 307 on its upper side to rotate counterclockwise. The winding column 305 rotates counterclockwise to wound up the charging cable 310.

[0021] like Figures 1-3 As shown, the working component assembly 2 includes a liquid-cooled heat sink 201 located on the upper part of the first mounting plate 103. Four AC-DC power converters are closely attached to both sides of the liquid-cooled heat sink 201. From top to left, the lower side of the first mounting plate 103 is provided with a power input interface 203, a circuit breaker 204, a surge protector 205, and a current transformer 206. A DC-DC charger is located on the upper part of the liquid-cooled heat sink 201. A control device 208 is located on the upper part of the third mounting plate 105. The end of the charging cable 310 passes through the first lead coil 308 and connects to the DC-DC charger. External AC power is connected through the power input interface 203. After the power supply is processed by the circuit breaker 204, surge protector 205 and current transformer 206 through "filtering-protection-distribution", it ensures that compliant power is delivered to the AC-DC power converter. The AC-DC power converter rectifies the AC power into high-voltage DC power and improves the power utilization rate through the PFC circuit. The high-voltage DC power is then delivered to the DC-DC charger. According to the vehicle BMS instructions, the DC-DC charger converts the high-voltage DC power into "voltage / current adapted to the battery" to achieve constant current-constant voltage charging. The DC-DC charger outputs the constant current-constant voltage high-voltage DC power to the vehicle battery through the charging cable 310 and the charging gun 311.

[0022] like Figure 1 , Figure 2 , Figure 7As shown, the placement component 4 includes a placement frame 401 disposed on the assembly box. The placement frame 401 has a fixing shell 402 inside. The fixing shell 402 has a spring 403 and a limiting block 404 inside. The spring 403 releases elastic potential energy upward to push the limiting block 404 to limit the installation of the charging gun 311, and further places the charging gun 311 in the placement frame 401.

[0023] like Figure 1 , Figure 2 As shown, a barrier filter plate 101 corresponding to the liquid-cooled radiator 201 is provided on one side of the main housing 1 through a rectangular through hole. An air exchange frame 102 is provided between the barrier filter plate 101 and the liquid-cooled radiator 201. The liquid-cooled radiator 201 dissipates heat and exchanges air inside the air exchange frame 102. A shielding plate 106 is provided on the top of the main housing 1 to shield the operation screen 5 from rain and snow.

[0024] like Figure 1 As shown, the upper front of the main housing 1 is provided with an operation screen 5 for operating and controlling the control device 208.

[0025] like Figure 1 As shown, the top of the main housing 1 is equipped with a signal antenna 6 for signal and network transmission.

[0026] like Figure 1 As shown, a camera 7 for monitoring the vicinity of the charging pile is provided at the lower part of the shield 106.

[0027] like Figures 1-8 As shown, the control device 208 is electrically connected to the liquid cooler 201, the ACDC power converter, the circuit breaker 204, the surge protector 205, the current transformer 206, the DCDC charger, the motor 301, the operation screen 5, the signal antenna 6, the operation switch, and the camera 7, respectively. The operation switch is electrically connected to the motor 301 through the control device 208.

[0028] Working principle: When the user prepares to charge the vehicle, the user removes the charging gun 311 from the placement frame 401. The user pulls the charging gun 311 outwards. During this process, the end of the charging gun 311 presses downwards against the limiting block 404 and compresses the spring 403. After the end of the charging gun 311 passes the limiting block 404, the spring 403 releases its elastic potential energy and pushes the limiting block 404 back to its original position. The user then turns on the motor 301 via an operating switch. The motor 301 drives the rotating gear 302 to rotate clockwise via its output shaft. The rotating gear 302 drives the first rotating drum 303 to rotate clockwise via its teeth. The first rotating drum 303 drives the rotating disk 304, winding column 305, upper baffle 306, and second rotating drum 307 on its upper side to rotate clockwise. The winding column 305 unwinds the charging cable 310 onto it. As the winding column 305 unwinds... First, the user plugs the charging gun 311 into the vehicle's charging port. Then, the user turns off the motor 301 via an operating switch. External AC power is connected through the power input interface 203. After being processed by the circuit breaker 204, surge protector 205, and current transformer 206 through "filtering-protection-distribution," the AC power ensures compliant power is delivered to the AC-DC power converter. The AC-DC power converter rectifies the AC power into high-voltage DC power and simultaneously improves energy utilization through the PFC circuit. The high-voltage DC power is then delivered to the DC-DC charger. According to the vehicle's BMS instructions, the DC-DC charger converts the high-voltage DC power into a voltage / current suitable for the battery, achieving constant current-constant voltage charging. The DC-DC charger outputs the constant current-constant voltage high-voltage DC power to the vehicle's battery through the charging cable 310 and the charging gun 311.

[0029] After charging is complete, the user removes the charging gun 311 from the vehicle's charging port. The user then turns on the motor 301 via an operating switch. The motor 301 drives the rotating gear 302 to rotate counterclockwise via its output shaft. The rotating gear 302 drives the first rotating drum 303 to rotate counterclockwise via its teeth. The first rotating drum 303 drives the rotating disk 304, winding column 305, upper baffle 306, and second rotating drum 307 on its upper side to rotate counterclockwise. The winding column 305 rotates counterclockwise to reel in the charging cable 310. As the winding column 305 reels in the cable, once the charging cable 310 is reeled in, the user turns off the motor 301 via an operating switch and places the charging gun 311 back into the placement frame 401. The end of the charging gun 311 presses downward against the limiting block 404 and compresses the spring 403. When the end of the charging gun passes the limiting block 404, the spring 403 releases its elastic potential energy and pushes the limiting block 404 upward to limit the charging gun 311.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
