Description

Technical Field

[0001] The utility model belongs to the technical field of charging piles, and particularly relates to an integrated storage and charging charging pile. Background Technique

[0002] The DC charging pile mainly consists of a power module, a control system, a display and operation interface, a communication system, and a safety protection system. The power module converts alternating current into high-voltage direct current and transmits electric energy to the battery of the electric vehicle through the charging gun interface, providing efficient, convenient, and safe charging services for electric vehicle users. It is widely used in public charging stations, commercial parking lots, logistics parks, residential areas, and other places. When the existing DC charging pile charges, it generally directly obtains electric energy from the main power supply network. The charging fee standard consists of electricity fee + service fee. Due to the policy of peak-valley time-of-use electricity price, the electricity cost is relatively high when the electric vehicle charges during the peak period. The valley electricity price period is late at night, and the valley electricity price period avoids the charging peak period, so the charging pile cannot effectively utilize the dividend of the valley electricity price, resulting in an increase in the charging cost.

[0003] The utility model patent with the patent announcement number CN216886314U and the announcement date of July 5, 2022, discloses an energy storage charging pile with a cooling and heat dissipation function, including an installation base. An energy storage charging pile is fixedly installed above the installation base. A first cooling cavity is opened at the lower end of the energy storage charging pile, and a second cooling cavity is opened at the upper end of the energy storage charging pile. A battery installation area is opened between the first cooling cavity and the second cooling cavity. Five installation baffles are equally spaced and fixedly installed on both sides inside the battery installation area. A pressure sensor is fixedly installed at the front end of one side of the installation baffle. A battery is slidably installed above the installation baffle. An audible and visual alarm is fixedly installed at a corner above the energy storage charging pile, and infrared receivers are annularly and equally spaced at the lower end of the audible and visual alarm. The audible and visual alarm is electrically connected to the infrared receivers. The front surface of the pressure sensor is attached to the rear surface of the first rotating door. The pressure sensor is electrically connected to the audible and visual alarm. Three liquid metal electromagnetic drive pumps are arranged inside both the first cooling cavity and the second cooling cavity. A circulation pipe is hermetically installed between the water outlet end of the upper liquid metal electromagnetic drive pump and the water inlet end of the lower liquid metal electromagnetic drive pump, and between the water inlet end of the upper liquid metal electromagnetic drive pump and the water outlet end of the lower liquid metal electromagnetic drive pump. The circulation pipe is arranged on both sides of the battery installation area, and both sides of the circulation pipe are attached to both sides of the battery.

[0004] The charging pile in this Chinese utility model patent has the following general usage methods and advantages: A liquid metal electromagnetic drive pump drives the liquid metal inside the circulation pipe to absorb the heat generated during the charging of the storage battery. Then, the heat dissipation fan groups on both sides of the energy storage charging pile generate airflows inside the first cooling chamber and the second cooling chamber to cool the liquid metal in the circulation pipe. And it has an anti-theft device to prevent the storage battery from being lost.

[0005] However, during the actual use of this charging pile, there are at least the following deficiencies, that is, the technical problems to be solved by this utility model: The heat dissipation and cooling system of the charging pile is only limited to the overall space of the charging pile, and the heat needs to be conducted from the battery cells in the battery pack to the pile body before being taken away, with very low efficiency and very limited effect.

[0006] Therefore, in summary, there is an urgent need for a charging pile with higher efficiency and stronger heat dissipation effect to solve the troubles of such problems. Utility Model Content

[0034] Embodiment 1

[0035] As shown in the attached Figures 1 - 4 figures, a combined charging and energy storage charging pile includes a battery compartment 1 provided in a cabinet a and a cooling compartment 2 having an air inlet. A wind guiding plate unit 3 is provided between the battery compartment 1 and the cooling compartment 2; the wind guiding plate unit 3 includes a wind duct plate 31, a plurality of wind guiding plates 33 provided on the wind duct plate 31 and used to partition the body of the cooling compartment 2 to form a plurality of wind guiding channels 32, and air outlets 34 provided on the wind duct plate 31 and corresponding to the wind guiding channels 32 one by one; the wind guiding channels 32 at least include two side wind guiding channels 321 and one middle wind guiding channel 322.

[0036] In this embodiment, the general usage method of the combined charging and energy storage charging pile is as follows:

[0037] The combined charging and energy storage charging pile can obtain electric energy from the main power supply network at night during off-peak electricity prices to charge the battery pack, and supply power to the charging pile through the battery pack during peak electricity price periods to meet the electricity demand during peak charging periods. Combining peak-valley electricity price arbitrage, making the most of peak-valley electricity prices, the economic benefits are maximized. However, the battery pack continuously generates heat during the charging and discharging process. If the heat cannot be dissipated in time, it will cause the temperature of the battery cells in the system to rise, and the temperature difference between the battery cells will continue to increase, resulting in a reduction in battery life. Therefore, a heat dissipation circulation system needs to be configured in the charging pile to maintain the normal operation of the charging pile; an air conditioning system is provided at the rear end of the cabinet a. The air conditioner adopts an upper air supply and lower air return structure form, and sends cold air for circulating heat dissipation into the cooling compartment 2 from the cooling compartment air inlet. When the cold air enters the cooling compartment 2, under the action of the resistance of the inner wall of the compartment, gravity, and the air inlet wind pressure, it continues to flow and encounters the wind guiding plate unit 3. The wind duct plate 31 first blocks the cold air, causing it to be shunted by the wind guiding plates 33 and distributed into the wind guiding channels 32, and continues to flow downward through the air outlets 34. The provided side wind guiding channels 321 and middle wind guiding channels 322 enable the cold air to flow downward relatively uniformly from the top of the battery compartment of the charging pile, with a more uniform heat dissipation effect and higher heat dissipation efficiency.

[0038] As a preferred embodiment of the present invention, a placement rack 12 for placing the battery pack 11 is provided in the battery compartment 1, and a longitudinal ventilation channel 13 is formed between the placement rack 12 and the inner wall of the battery compartment 1, and the longitudinal ventilation channel 13 is connected to the side air guide channel 321 through the air outlet 34.

[0039] In this embodiment, the battery packs 11 are stacked up and down in the battery compartment 1, and the battery packs 1 are fixedly supported by the placement rack 12. Cold air enters the lower and middle part of the battery compartment from the air outlet 34 on the cooling compartment 2. The longitudinal ventilation channel 13 between the placement rack 12 and the inner wall of the battery compartment 1 is used to guide the cold air to prevent the temperature difference between the top battery pack and the bottom battery pack from being too large, which affects the life of the battery pack;

[0040] It is understandable that in order to further improve the cooling effect, the battery compartment 1 can be sealed and covered with thermal insulation cotton to prevent the air conditioning cold from entering other compartments through the gaps, ensuring that the battery compartment temperature is maintained within an appropriate range; in order to further avoid safety hazards, an aerosol automatic fire extinguishing system is provided inside the compartment. When a fire occurs in the protection area, the aerosol fire extinguishing device converts the solid fire extinguishing agent into tiny particles of gaseous substances, and forms a mist through the nozzle, quickly covering the fire source area, thereby achieving the purpose of controlling and extinguishing the fire source. The above-mentioned thermal insulation cotton and aerosol automatic fire extinguishing system are common knowledge, so they will not be repeated in this embodiment.

[0041] As a preferred embodiment of this embodiment, the battery pack 11 includes a shell 111, a battery pack vent 112 arranged on the shell 111 and located at the lower end of the middle air guide channel 322, a plurality of battery pack air inlets 113 arranged on the side wall of the shell 111, a heat conduction plate 114 arranged in the shell 111 to form a sandwich air duct, and a heat dissipation fan 115 arranged on the shell 111.

[0042] In this embodiment, the battery pack 11 adopts the form of three rows of battery cell components arranged side by side, and a single battery cell assembly is composed of a plurality of single battery cells. A heat conducting plate 114 is provided between adjacent battery cells, and a ventilation duct is provided between adjacent battery cell components. The ventilation duct cooperates with the heat dissipation fan 115 of the battery pack to disperse the cold air entering the battery pack 11. The heat conducting plate 114 is preferably an aluminum sandwich duct plate, and its number and position correspond to the air inlet 113; the battery pack vent 112 of the battery pack 11 arranged at the upper end of the shell 111 corresponds to the air outlet 34 of the middle air guide channel 322, and the battery pack air inlet 113 on the side wall of the shell 111 corresponds to the air outlet 34 of the side air guide channel 321. Cold air is poured into the battery pack from multiple directions of the battery pack, flows into the ventilation duct after passing through the heat conducting plate 114, and is then discharged from the heat dissipation fan 115, completing the heat dissipation cycle in the battery compartment 1 and the battery pack 11.

[0043] As a preferred embodiment of the present embodiment, a charging and discharging module compartment 4 is further included, which is provided with a compartment air inlet 41 and a compartment air outlet 42 , and an exhaust fan 43 is provided at the compartment air outlet 42 .

[0044] In this embodiment, a heat dissipation structure of forced air cooling is provided on the charging and discharging module bin 4, including a bin air inlet 41 arranged on the upper sides of the cabinet a, a bin air outlet 42 and an exhaust fan 43 on the back of the cabinet a. When the charging and discharging module is working, a large amount of heat will be generated and accumulated in the module bin, and the heat will be mainly discharged through the exhaust fan 43 in cooperation with the internal fan of the charging and discharging module; there is a 90° angle between the external air inlet direction of the bin air inlet 41 and the heat dissipation air inlet direction of the charging and discharging module, which effectively prevents external wind from directly entering the charging and discharging module bin 4, reduces the influence of dust on the charging and discharging module, and ensures that the charging and discharging module can work stably for a long time. Furthermore, shutters and filter cotton can be provided at the bin air inlet 41, and the incoming air enters the charging and discharging module bin after multiple turns. This structure can effectively block dust particles and rainwater outside the shutters, and has strong rainproof, waterproof and sand and dustproof functions.

[0045] Compared with the prior art, the technical solution described in this embodiment has the following advantages: unlike the traditional charging pile with heat dissipation function which only has the function of cooling the temperature inside the compartment, the present application links the heat dissipation cycle in the battery pack with that in the battery compartment, and sets up a dual heat dissipation cycle system of the battery compartment and the charging and discharging module compartment, so as to ensure that the battery and the module operate within the specified temperature range, thereby effectively improving the heat dissipation efficiency of the storage-charging charging pile.

[0046] Embodiment 2

[0047] The difference between this embodiment and the first embodiment is that the air volume and direction of the air guide plate unit can be adjusted. Figure 4 As shown, the details are as follows:

[0048] The air guide plate 33 has at least one free end 331 close to the air inlet of the cooling chamber 2 , and the air duct plate 31 is provided with a first driving member 332 connected to the free end 331 and used for driving the air guide plate 33 to move.

[0049] In this embodiment, a plurality of air guide plates 33 are hinged to each other, and an endpoint is formed at the hinge of every two air guide plates 33. The end close to the air inlet of the cooling bin 2 is called a free end 331, and a first driving member 332 for driving the free end 331 to move is provided near the front end of the air inlet of the cooling bin 2. The reciprocating movement of the free end 331 at the front end of the air inlet of the cooling bin 2 can change the air volume entering different air guide ducts 32, and effectively distribute different air volumes according to the temperature of different areas in the battery bin, thereby saving energy and improving efficiency.

[0050] As a preference of this embodiment, the first driving member 332 includes a groove 3321 provided on the air duct plate 31, a threaded rod 3322 rotatably connected to the groove 3321 at both ends, a moving block 3323 screwed on the threaded rod 3322 and slidably connected to the groove 3321, a connecting rod 3324 provided on the moving block 3323 and connected to the free end 331, and a first motor 3325 with an output end connected to the end of the threaded rod 3322; there are at least two moving blocks 3323, and the two moving blocks 3323 approach or move away from each other under the drive of the threaded rod 3322; adjacent two free ends 331 are respectively connected to the two moving blocks 3323 through the connecting rod 3324.

[0051] In this embodiment, the first motor 3325 drives the threaded rod 3322 to rotate, and the moving block 3323 moves in the groove 3321. The groove 3321 is arranged parallel to the air inlet of the cooling chamber 2. To further optimize the adjustment method, multiple air guide plates 33 form two free ends to evenly distribute the air volume of the three air ducts. Therefore, two moving blocks 3323 are arranged on the threaded rod 3322. In this case, opposite threads are provided at the left and right ends of the threaded rod 3322. When the threaded rod 3322 rotates, the moving directions of the two moving blocks 3323 are opposite. To prevent the connection between the moving block 3323 and the threaded rod 3323 from failing, two blocking blocks can be arranged on the middle section of the threaded rod 3322 and fixedly connected to the groove 3321. The blocking blocks limit the excessive deviation of the moving block 3323.

[0052] Compared with the prior art, the technical solution of this embodiment has the advantage that: without changing the air volume output by the cooling system, the air volume of the air guide channel can be adjusted in terms of direction and magnitude. In actual situations, the same amount of energy is consumed, and the cooling effect is maximized.

[0053] Embodiment Three

[0054] The difference between this embodiment and Embodiment One is that an air volume adjustment component for adjusting the air volume entering the battery pack is added to the battery pack, as shown in the attached Figure 8 figure, and the details are as follows:

[0055] The battery pack 11 further includes an air regulating assembly 116 disposed within the housing 111 and configured to control the ventilation volume of the air inlet 113 of the battery pack; the air regulating assembly 116 includes an air regulating plate 1161, air regulating openings 1162 disposed on the air regulating plate 1161 and corresponding to the air inlet 113 of the battery pack one by one, a sliding groove 1163 disposed on the inner bottom surface of the housing 111 for the air regulating plate 1161 to slide thereon, a through groove 1164 disposed at one end of the air regulating plate 1161, an upper rack 1165 and a lower rack 1166 respectively disposed on the inner side walls of the through groove 1164, a second motor 1167 disposed on the housing 111, a driving wheel 1168 disposed on the output shaft of the second motor 1167 and meshing with the lower rack 1166, and a driven wheel 1169 whose two side ends are respectively meshed with the driving wheel 1168 and the upper rack 1165.

[0056] In this embodiment, the air regulating assembly 116 is disposed inside the housing provided with the air inlet 113 of the battery pack, and is used to adjust the size of the air inlet 113 of the battery pack, and reduce the temperature difference between the battery cells in the battery pack; the air regulating plate 1161 is vertically installed in the sliding groove 1163 and moves left and right. In the initial state, the air regulating openings 1162 correspond to the air inlet 113 of the battery pack one by one, and the air inlet 113 of the battery pack is fully opened; when it is necessary to reduce the air inlet 113 of the battery pack, the second motor 1167 is started. The driving wheel 1168 is disposed on the output shaft of the second motor 1167. The second motor 1167 is a rotary motor that drives the driving wheel 1168 to rotate, thereby driving the lower rack 1166 and the driven wheel 1169 to rotate synchronously. The upper rack 1165 moves in the same direction as the lower rack 1166 under the drive of the driven wheel 1169, thereby driving the relative position of the entire air regulating plate 1161 and the housing to change, and the air inlet 113 of the battery pack is partially blocked by the air regulating plate 1161.

[0057] The technical solution of this embodiment has the following advantages compared with the prior art: on the above basis, it can further reduce the temperature difference between the battery cells in a single battery pack, thereby reducing the temperature difference of the system battery cells and ensuring the service life and efficiency of the battery.
