Description

Technical Field

[0001] The utility model relates to the field of charging terminal equipment, and in particular to a liquid-cooled supercharging terminal. Background Art

[0002] With the increasing use of new energy electric vehicles, the power required for electric vehicle charging is increasing. High-power fast charging is becoming more and more popular, and it is also the future development trend of electric vehicle charging piles.

[0003] At present, since the charging gun is affected by temperature during charging, the charging current is relatively small and the charging speed is relatively slow. Another point is that the charging noise is relatively large: traditional air-cooled charging piles and semi-liquid-cooled charging piles have built-in air-cooled charging modules, and the modules have built-in multiple high-speed small fans, and the operating noise exceeds 50db; in addition, the charging pile also contains a cooling fan. Currently, when the air-cooled charging pile is used and running at full power, the noise is usually above 60dB; another point is that the gun line is relatively thick, the cost is high, and the gun line is heavy, and the operation is more laborious. The reason for this is that the heat generated by the cable is proportional to the square of the current. Therefore, in order to reduce the heat generated by the cable and avoid overheating, the cross-sectional area of the wire must be increased, resulting in an increase in the weight of the gun line of the traditional air-cooled charging pile, a larger curvature of the coiled gun line, and a higher cost for manufacturing the gun line.

[0044] The liquid-cooled supercharging terminal includes a charging cabinet 100, a charging front door 200, a charging component, a charging gun, a charging gun line, a gun line power-assisted lifting device, and a liquid cooling device 127;

[0045] The charger front door 200 is rotatably connected to the charger cabinet 100; the charging unit and the liquid cooling device 127 are respectively installed inside the charger cabinet 100; the liquid cooling device 127 removes heat generated by the charging gun wire through the flow of coolant in the cooling pipe;

[0046] The charging gun is electrically connected to the charging component via a charging gun wire, wherein the charging gun is detachably connected to the outer wall of the charging cabinet 100;

[0047] The gun line booster lifting device is installed at the top of the charging cabinet 100. A balancer 302 is installed inside the gun line booster lifting device. The gun line booster lifting device is used to pull the charging gun line through the balancer 302 and assist in retracting the charging gun head.

[0048] The charging gun wires include a negative wire 116 and a positive wire 117 .

[0049] The gun line power-assisted lifting device further includes a cover plate 300 , a base plate 301 , a guide roller 303 , and a cable clamp assembly 304 ;

[0050] The base plate 301 is installed on the top of the charging cabinet, and the cover plate 300 is fixedly connected to the base plate 301, and enclosed with the base plate 301 to form an installation space for installing multiple components including a balancer 302, a guide roller (303) and a cable clamp assembly 304.

The other end of the traction rope is connected to the cable clamp assembly 304, and the cable clamp assembly 304 is connected to the charging gun line. Among them, the guide roller 303 is used to guide the traction rope.

[0051] The specific installation steps are as follows: first, pass the fixing plate of the balancer 302 through the rivet screws on the base plate 301, and tighten it with flange nuts. Then, place the base plate 301 on the top of the charging pile, and use the combination screws to pass through the fixing holes of the base plate 301 and tighten it with the blind hole nut column on the top of the charging pile. Then, pull the traction rope out and pass it through the guide roller 303. The end of the traction rope is then fixed to the cable clamp assembly 304.

The liquid-cooled supercharging terminal gun line lifting device adopts a systematic structural design, which is simple and compact, with low production cost, high assembly efficiency, easy disassembly and installation, and convenient maintenance; the charging machine gun line lifting device adopts a waterproof structural design, meets the IP54 protection level, and can be used in harsh outdoor environments; in addition, the charging machine gun line lifting device mainly uses the lifting force of the balancer to lift the charging machine gun line, which can complete the automatic bundling of the charging machine gun line, reduce the process of winding the gun line, and will not be troubled by the thick gun line, heavy cable, and the difficulty of winding it, which greatly reduces the work intensity of the operator, making the use of the charging machine gun line more practical and convenient, improving the working method, and is conducive to vigorous promotion, providing users with a more convenient and safe use experience.

[0052] Example 2:

[0053] This embodiment provides a charging principle for a liquid-cooled supercharging terminal. First, 220V AC power is introduced from the charging internal unit to the input terminal of the micro leakage circuit breaker 129. Then, the output terminal of the micro leakage circuit breaker 129 is led to the 12V power supply UP1130, the BMS auxiliary power supply UP3131, and the switching power supply UP5136. The 12V power supply UP1130 converts the 220V AC power into 12V DC power, which is then supplied to the billing control unit TCU device 212 and the charging controller AM1132. The BMS auxiliary power supply UP3131 converts the 220V AC power into 12V DC power, which is then connected to the BMS auxiliary power relay 138. The charging controller AM1132 controls the opening and closing of the BMS auxiliary power relay 138. Cut off the power supply to the charging gun gun lines A+ and A-, the switching power supply UP5136 converts the AC 220V into DC 24V, and then supplies power to the liquid cooling device 127. The charging controller AM1132 sends instructions to the liquid cooling device 127 through the 485 interface: control the liquid cooling device 127 to start or stop the liquid cooling system; the emergency stop button 135 normally closed contact connects the R pole of the DC contactor 121 on the positive and negative lines to D7 and D9 in the charging controller AM1132. In an emergency, pressing the emergency stop button will cut off the DC contactor 121 on the positive and negative lines, and the charging gun will stop charging; the DJSF2699 DC meter 137 takes the L live wire and N neutral wire of the AC 220V from the switching power supply UP5136, and D V1+ in JSF2699 DC meter 137 is connected to DC+ contactor A1+114, V1- in DJSF2699 DC meter 137 is connected to DC- contactor A2-114, I1+ in DJSF2699 DC meter 137 is connected to 1119 in shunt RS, and I1- in DJSF2699 DC meter 137 is connected to 2119 in shunt RS. The voltage and current on the positive and negative charging lines are sampled respectively. DJSF2699 DC meter 137 converts the collected current and voltage values into electricity measurement values and transmits them to A1 and B1 in the billing control unit TCU device 212 through RS485 interfaces PJ13 and PJ14. The unit TCU device 212 takes 12V DC power from the 12V power supply UP1130. The billing control unit TCU device 212 is connected to the card swiping printed circuit board 209 through the RS232 interface. The billing control unit TCU device 212 converts the power metering value into the charging amount and transmits it to the charging display screen 208 along with the corresponding voltage and current parameters for user viewing and operation. The liquid-cooled supercharging terminal debugging work also performs parameter setting and modification through the charging display screen 208. The gun electromagnetic drive module 139 connects D3 and D4 in the charging controller AM1132 and EL+ and EL- in the charging gun line to monitor whether the charging gun is plugged in and locked reliably, and feeds back the signal to the charging controller AM1132.C9 in the charging controller AM1132 is connected to A1+ in the DC+ contactor 121, and C11 in the charging controller AM1132 is connected to A2- in the DC- contactor K2121 for input voltage sampling. C13 in the charging controller AM1132 is connected to A2- in the DC+ contactor 121, and C15 in the charging controller AM1132 is connected to A1+ in the DC- contactor K2121 for output voltage sampling. C17 in M1132 is connected to terminal 1 of shunt 121, and C18 in the charging controller AM1132 is connected to terminal 2 of shunt 121 for current sampling. The charging controller AM1132 also connects to S+, S-, CC1, PE, T1+, T2+, RS+, and RS- in the charging gun to collect charging communication, connection confirmation, gun temperature, guidance, and electric lock status feedback. This controls the charging parameters of the charging gun and adjusts them in real time until charging is complete. The liquid-cooled supercharging terminal features a rational layout of electrical components and a compact structure. Plastic wiring troughs surround the electrical components to ensure separation of strong and weak currents, ensuring safe and reliable operation.

[0054] Example 3:

[0055] Based on the circuit structure provided in the second embodiment, this embodiment follows the same structure, with the difference being that a liquid cooling device is connected.

[0056] Under the conditions of the gun line assisted lifting device in Example 1, the cooling pipeline includes a liquid outlet pipe 124, a positive electrode return pipe 126 and a negative electrode return pipe 125; the liquid outlet pipe 124 is bifurcated into two pipes near the charging gun and is respectively connected to the positive electrode return pipe 126 and the negative electrode return pipe 125; the charging gun line includes a negative electrode line 116 and a positive electrode line 117.

[0057] Among them, the coolant in the liquid outlet pipe 124 flows out of the liquid cooling device 127, and the coolant in the positive return pipe 126 and the negative return pipe 125 flows into the liquid cooling device 127; the positive return pipe 126 at least partially fits the positive electrode line 117, and the negative return pipe 125 at least partially fits the negative electrode line 116, so that the coolant in the cooling pipe and the charging gun line can fully exchange heat.

[0058] In some embodiments, the liquid outlet pipe 124 can be connected to the positive electrode liquid return pipe 126 and the negative electrode liquid return pipe 125 through a three-way joint.

[0059] The liquid cooling device 127 also includes a hydraulic pump, a positive electrode liquid return port connected to the positive electrode liquid return pipe 126, a negative electrode liquid return port connected to the negative electrode liquid return pipe 125, and a liquid outlet connected to the liquid outlet pipe 124; the hydraulic pump is used to pump the coolant to move in the cooling pipeline.

[0060] The liquid cooling device 127 further includes a radiator and a fan; the radiator is used to absorb heat from the coolant in the cooling pipeline, and the air outlet direction of the fan is toward the radiator to cool the radiator.

[0061] The side walls of the charging cabinet 100 are provided with enclosed air ducts 128; the air inlet and air outlet of the enclosed air duct 128 are respectively arranged on two adjacent side walls, with the air inlet direction and the air outlet direction of the fan perpendicular to each other. Because conventional charging guns have high gun wire temperatures during charging, low charging currents, and relatively low charging efficiency, the principle of the liquid-cooled supercharging terminal of the utility model is mainly to use liquid cooling technology to provide constant temperature control. The liquid cooling device contains a hydraulic pump, radiator, fan, fuel tank, etc., and has inlet / outlet pressure detection and inlet / outlet / ambient oil temperature detection functions. The liquid cooling system has a heat dissipation power of 2.4KW and is equipped with four coolant interfaces: DC- return port, DC+ return port, liquid outlet, and standby port. The liquid cooling principle of the liquid cooling device is as follows: the switching power supply UP5136 converts AC 220V into DC 24V to power the liquid cooling device 127. When the charging gun starts charging, the charging controller AM1132 sends a command to the liquid cooling device 127 through the 485 interface: start the liquid cooling device 127, and the hydraulic pump in the liquid cooling device starts to make the coolant flow out of the liquid cooling device 127. The liquid outlet flows along the plastic oil pipe to the charging gun, and is forked inside the charging gun to the liquid-cooled charging gun negative line 116 and the liquid-cooled charging gun positive line 123 using a three-way interface, and then flows back to the liquid cooling device 127 along the plastic oil pipe. The coolant takes away the heat from the charging gun and flows back to the liquid cooling device 127. The high temperature of the coolant is transferred to the radiator through the heat dissipation coil, and the cooling fan is started to blow towards the radiator. The wind takes away the heat from the radiator, and the hot air flows out of the cabinet along the closed air duct 128, thereby reducing the coolant temperature.

[0062] like Figure 6 As shown, the coolant circulates, continuously reducing the temperature of the charging gun and the positive and negative wires. The current flowing through the charging gun wire can reach up to 600A, achieving constant temperature and ultra-fast charging of the gun wire, effectively improving the charging efficiency. In addition, the charging interface of the liquid-cooled supercharging charging pile is set at the bottom of the charging pile, and the cable bends smoothly, allowing the current to flow more evenly through the cable, reducing the impact of sharp bending of the cable on charging, and effectively improving the charging efficiency. In addition, the heat dissipation outlet of the liquid cooling equipment in the liquid-cooled supercharging charging pile is connected to the cabinet with a closed air duct, directly exhausting the hot air out of the cabinet. The closed air duct separates the hot air from the cold air, has a stronger tolerance to ambient temperature, better heat dissipation effect, and further improves the heat dissipation efficiency. By utilizing liquid cooling technology, closed air ducts, and improving charging efficiency, the liquid-cooled supercharging charging pile achieves efficient, safe, and environmentally friendly charging services and reduces the operating costs of charging facilities.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.
