[0022] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0023] A charging stack host, such as Figure 1-Figure 5 A distribution area 2 is provided in the cabinet, and power areas are provided on both sides of the distribution area 2. A charging module 7, a power distribution unit 8 and a DC output copper bus are provided in the power area. The charging module 7 is provided on the upper side of the intelligent power distribution unit 8. A control unit 22 and an AC input unit 15 are provided in the distribution area 2. After the AC power is converted into DC power by the charging module 7, it is connected to the power distribution unit 8 through the DC output terminal and the DC power line. The DC power line is respectively routed along the inner sides of the left and right side panels of the cabinet to avoid AC / DC interference problems.

[0024] Specifically, the power area includes a first power area 1 on the left and a second power area 3 on the right, and the power distribution area 2 is arranged in the middle.

[0025] The first power zone 1 includes a left front door 4, a left front door air inlet window 5, a noise reduction component 6, a charging module 7, an intelligent power distribution unit 8, a DC output copper bus 9, a left rear door 10, an air outlet window 11, and a heat dissipation fan 12.

[0026] The second power zone 3 includes a right front door 18 , a left front door air inlet window 5 , a noise reduction component 6 , a charging module 7 , an intelligent power distribution unit 8 , a DC output copper bus 19 , a right rear door 20 , an air outlet window 11 , and a heat dissipation fan 12 .

[0027] The power distribution area 2 includes a middle front door 13 , a control unit 22 , an AC input unit 15 , and a middle rear door 17 .

[0028] Two rows of charging modules 7 are arranged in the upper part of the cabinets of the first power zone 1 and the second power zone 3, which are installed from the front door side and wired from the rear of the charging modules 7. Intelligent power distribution units 8 are arranged in the lower part, which are installed from the front door side and DC output copper bars 9 and 19 are installed from the rear of the intelligent power distribution unit 8. The control unit 22 is arranged in the upper part of the front door side of the distribution zone 2, and the AC input unit 15 is arranged at the rear side.

[0029] The AC input copper bus 16 of the AC input unit 15 is connected to the AC input line to supply power to the entire pile. The AC power is respectively sent to the charging modules 7 at the upper left, lower left, upper right and lower right positions via four molded case circuit breakers 21. The lower back of the charging module is equipped with an AC input terminal and the upper back is equipped with a DC output terminal. The power line is connected from the molded case circuit breakers 21 at four positions to the AC input terminals of the charging modules 7 at four positions. This arrangement has the shortest power line path and the lowest cost.

[0030] After the AC power is converted into DC power by the charging module 7, it is connected to the intelligent power distribution unit 8 through the DC output terminal and power line. The DC power line is routed along the inner side of the left and right side panels of the cabinet, and is separated from the AC power line in the middle position, avoiding the AC and DC interference problem. The back of the intelligent power distribution unit 8 in the left and right power zones is equipped with DC output copper bars 9 and 19 respectively, with a total of 24 external connection points, which can be connected to the charging terminal to support 24 guns to charge at the same time.

[0031] The intelligent power distribution units 8 in the left and right power zones are interconnected by cables to form a Mobius loop, which enables each charging gun to flexibly call one or more charging modules according to the actual needs of the vehicle, meeting the charging needs of different models and achieving the maximum utilization of the charging modules. The rated power of the charging modules 7 in the four positions is 960kW in total. When a 600kW liquid-cooled terminal is configured, the intelligent power distribution unit can intelligently allocate and call the modules to meet the 600kW charging demand.

[0032] This solution supports up to 24 charging guns charging at the same time, can be used with liquid-cooled guns, and supports a maximum charging power of 600kW. According to the actual charging needs of different models, the number of charging modules is intelligently allocated, thereby improving the utilization efficiency of charging equipment.

[0033] In this embodiment, the control unit 22 is located above the front side of the middle power distribution area, separated from the power area, and the control unit wiring is also designed with an independent path, separated from the power line, avoiding interference problems between AC, DC, and control lines.

[0034] In this embodiment, an air inlet window 10 is provided at the lower part of the left front door. The air inlet window is in the form of a shutter and is equipped with dustproof cotton, which is ventilated, waterproof and dustproof; a noise reduction component 6 is provided at the upper part of the left front door. The noise reduction component is equipped with sound insulation cotton, and can also be installed with sound-absorbing cotton or microporous sound-absorbing panels, which reduces the noise of the fan in the charging module, which is the main noise source. The air enters from the air inlet window 10, passes through the charging module 7 on the upper side of the first power zone and the DC output unit 8 on the lower side, and the heat generated by it is discharged from the left rear door outlet window 11 through the left rear door heat dissipation fan 12. The air duct is independent and clear, which effectively ensures the heat dissipation of the main heat source, namely the charging module and the DC output unit. The same applies to the second power zone.

[0035] An air inlet window 14 is provided at the lower part of the middle front door 2. The air inlet window is in the form of shutters and is equipped with dustproof cotton, which is ventilated, waterproof and dustproof. Part of the air is driven by the heat dissipation fan of the rear door, flows through the ventilation holes of the AC wiring baffle on the lower side of the middle part to dissipate the heat of the AC input unit, and part of the air flows upward through the control unit on the upper side of the middle part due to the action of the fan in the charging module, and then flows into the charging modules on both sides, and finally uniformly discharged from the rear door air outlet window, realizing the heat dissipation of the control unit on the upper side. The air inlet 14 of the middle front door is located on the lower side, and the control unit 22 is located on the upper side. The control unit is far away from the air inlet in the air duct, which can effectively reduce the influence of moisture and dust on the circuit board and auxiliary source in the control unit.

[0036] The above layout is implemented in this way, and the cabinet space utilization rate is high, the overall size is small, the cost is low, the cabinet height is low, the installation height position of the charging module is moderate, and it is more convenient to install and maintain the charging module.

[0037] The reasonable layout of the units in the cabinet solves some problems in the prior art caused by the unreasonable arrangement of the units, such as interference between AC and DC lines, poor heat dissipation, and high noise. The reasonable layout of the units in the cabinet makes the cabinet small in size and low in cost. The charging module is in a moderate position for easy maintenance.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed and modified in any way.
