Description

Technical Field

[0001] This application relates to the field of energy storage cabinet technology, and in particular to a distributed photovoltaic power generation energy storage station. Background Technology

[0002] With the rapid development of new energy electric vehicles, battery swapping stations have become an indispensable energy service infrastructure for electric vehicles after their large-scale industrialization. A battery swapping station is a device used to provide users with rechargeable batteries. Resembling a storage locker, it contains different battery compartments, each holding one power battery. The locker is controlled by a controller to open and close the door, allowing for battery retrieval and storage. Each battery compartment is connected to a charger, which automatically charges the battery within.

[0003] In existing technologies, vehicle-mounted distributed photovoltaic (PV) energy storage stations are commonly used to provide DC fast charging for the batteries in the battery swapping cabinet. A typical distributed PV energy storage station mainly includes a cabinet, which consists of a top cover, cabinet body, electrical door, battery door, base, partitions, cable tie, multiple shelves, and multiple crossbeams; a centrifugal fan, located between the top cover and the cabinet body; a PV inverter; an electrical board, which includes a meter, energy management system, temperature and humidity transmitter, switching power supply, single-phase energy meter, single-phase data acquisition meter, multiple input / output terminals, and multiple control switches; multiple inlet / outlet tower-shaped protective sleeves and water immersion sensors; multiple energy storage batteries, arranged in an array on the shelves and fixed by crossbeams; and a battery management system located on top of the multiple energy storage batteries.

[0004] However, the batteries in the energy storage cabinet cannot achieve complete energy conversion when storing or releasing electrical energy. Some of the energy is released as heat, so heat dissipation is required to maintain the working environment of the batteries inside the energy storage cabinet. Utility Model Content

[0005] To improve the heat dissipation performance of the energy storage station's cabinet, this application provides a distributed photovoltaic power generation energy storage station.

[0006] The distributed photovoltaic power generation and energy storage station provided in this application adopts the following technical solution:

[0007] A distributed photovoltaic power generation and energy storage station includes a cabinet, in which a first mounting cavity and a second mounting cavity are formed. A first cabinet door and a second cabinet door are hinged to the cabinet, and the first cabinet door and the second cabinet door respectively cover the outside of the first mounting cavity and the second mounting cavity.

[0008] The first mounting cavity is provided with a plurality of battery compartments, and water-cooling plates are detachably installed on the bottom of each of the plurality of battery compartments. An integrated water chiller is fixedly installed in the second mounting cavity. The integrated water chiller includes a water supply pipe and a return pipe. A plurality of first branch pipes are connected to the water supply pipe, and a plurality of second branch pipes are connected to the return pipe. The water outlets of the plurality of first branch pipes are respectively connected to the water inlets of the cooling plate, and the water inlets of the plurality of second branch pipes are respectively connected to the water outlets of the cooling plate.

[0009] A water leakage detection module is fixedly connected inside the cabinet.

[0010] By adopting the above technical solution, during the discharge process of the battery pack inside the energy storage station cabinet, the water pump in the integrated water chiller draws water and circulates it through the water supply pipe, the first branch pipe, the water-cooled plate, the second branch pipe, and the return pipe. This allows the cooling water to circulate within the water-cooled plate, carrying away the heat generated during battery pack discharge. The integrated water chiller then cools the returning cooling water, achieving the technical effect of circulating cooling to cool the batteries in the battery compartment. A leakage detection module inside the cabinet can monitor leakage in real time. When leakage occurs in the water supply pipe, return pipe, first branch pipe, or second branch pipe, the leakage detection module can issue an alarm, allowing operators to promptly shut down the energy storage station for maintenance.

[0011] Preferably, a plurality of first carriers and a plurality of second carriers are fixedly connected to the two inner sidewalls opposite to each other in the first mounting cavity. The axial directions of the first carriers and the second carriers are both horizontally arranged along the depth direction of the cabinet, and the first carriers and the second carriers are opposite to each other.

[0012] Mounting plates are fixedly connected to both sides of the water-cooled plate. Mounting seats are fixedly installed at the bottom of the first and second carriers. Slots that are compatible with the mounting plates are opened on the opposite side of the two mounting seats. The two mounting plates can be detachably installed in the two slots.

[0013] By adopting the above technical solution, the battery pack can be installed in the battery compartment through the first carrier and the second carrier respectively. The water-cooling plate can be installed under the battery pack through the two mounting seats under the first carrier and the second carrier, so as to facilitate the cooling of the battery pack through the water-cooling plate.

[0014] Preferably, the mounting base has a mounting groove, in which a plurality of rollers are rotatably mounted. A baffle is fixedly connected to the mounting base, the baffle is located above the opening of the mounting groove, and a plurality of clearance holes are formed through the baffle to allow the rollers to extend.

[0015] By adopting the above technical solution and by setting the rollers, when the operator slides the mounting plates on both sides of the water-cooled plate into or out of the slot, the rollers rotate at the bottom of the mounting plates, which can improve the convenience of the operator in installing or removing the water-cooled plate.

[0016] Preferably, a limiting protrusion is fixedly connected to the top of the mounting plate, and a limiting groove adapted to the limiting protrusion is provided on the top inner wall of the slot, and the limiting protrusion is embedded in the limiting groove.

[0017] By adopting the above technical solution, the position of the mounting plate and water-cooled plate can be further limited by the limiting protrusion, thereby improving the stability of the water-cooled plate mounting structure.

[0018] Preferably, the surface of the water-cooled plate is coated with an anti-condensation coating.

[0019] By adopting the above technical solution and setting an anti-condensation coating, the occurrence of condensation of moisture in the air on the surface of the water-cooled plate can be reduced.

[0020] Preferably, the water leakage detection module includes a water immersion sensor and a buzzer. The buzzer is fixedly installed on the cabinet. The water immersion sensor includes a water leakage sensing rope and a controller. The water leakage sensing rope is fixedly installed on the bottom inner wall edge of the first mounting cavity and the second mounting cavity. The signal input terminal of the controller is connected to the water leakage sensing rope, and the signal output terminal of the controller is connected to the signal input terminal of the controller.

[0021] By adopting the above technical solution and setting up a water immersion sensor, when the water supply pipe, return pipe, first branch pipe or second branch pipe in the cabinet leaks, and the leaking cooling water comes into contact with the leakage sensing rope, the controller of the water immersion sensor controls the buzzer to sound an alarm, prompting the on-site operator to alert that there is a cooling water leak in the cabinet.

[0022] Preferably, the cabinet includes a back panel, and through holes are provided on both sides of the second mounting cavity on the back panel and the second cabinet door;

[0023] Two mounting frames are fixedly installed on the inner wall of the second mounting cavity. A set of inclined shielding blades are fixedly connected to the mounting frames, and the two sets of shielding blades respectively shield the two sides of the integrated water chiller.

[0024] By adopting the above technical solution, the ventilation requirements of the integrated chiller can be met through the through holes on the back panel and the second cabinet door. At the same time, the shielding blades can reduce the occurrence of external rainwater entering the cabinet through the through holes.

[0025] In summary, the distributed photovoltaic power generation and energy storage station proposed in this application has at least one of the following beneficial technical effects:

[0026] 1. During the discharge process of the battery pack inside the energy storage station cabinet, the water pump in the integrated water chiller draws water and passes it through the water supply pipe, the first branch pipe, the water cooling plate, the second branch pipe, and the return pipe, so that the cooling water circulates in the water cooling plate, carrying away the heat generated during the discharge process of the battery pack. The integrated water chiller can cool the return cooling water, achieving the technical effect of circulating cooling to cool the batteries in the battery compartment.

[0027] 2. By setting up a water immersion sensor, when the water supply pipe, return pipe, first branch pipe or second branch pipe in the cabinet leaks, and the leaking cooling water comes into contact with the leakage sensing rope, the controller of the water immersion sensor will control the buzzer to sound an alarm, alerting the on-site operator that there is a cooling water leak in the cabinet.

[0034] The following combination Figures 1-5 This application will be described in further detail.

[0035] Example

[0036] This application discloses a distributed photovoltaic power generation and energy storage station. (Refer to...) Figures 1-5It mainly includes a cabinet body 1. The cabinet body 1 is divided into a first mounting cavity and a second mounting cavity by a partition. A first cabinet door 11 and a second cabinet door 12 are hinged on the cabinet body 1. The first cabinet door 11 and the second cabinet door 12 respectively cover and shield the outside of the first mounting cavity and the second mounting cavity.

[0037] To ensure the sealing effect of the first and second mounting cavities, sealing rings are installed on the inner side walls of the first cabinet door 11 and the second cabinet door 12.

[0038] The first mounting cavity contains several battery compartments, and water-cooled plates 2 can be detachably installed on the bottom of each battery compartment. The second mounting cavity contains an integrated water chiller 3, which includes a water supply pipe 31 and a return pipe 32. Several first branch pipes 311 are connected to the water supply pipe 31, and several second branch pipes 321 are connected to the return pipe 32. The outlets of the first branch pipes 311 are connected to the inlets of the cooling water plates, and the inlets of the second branch pipes 321 are connected to the outlets of the cooling water plates.

[0039] A water leakage detection module is fixedly connected inside the cabinet 1. The water leakage detection module includes a water immersion sensor and a buzzer. The buzzer is fixedly installed on the cabinet 1. The water immersion sensor includes a water leakage sensing rope 4 and a controller. The water leakage sensing rope 4 is fixedly installed on the bottom inner wall edge of the first mounting cavity and the second mounting cavity. The signal input terminal of the controller is connected to the water leakage sensing rope 4, and the signal output terminal of the controller is connected to the signal input terminal of the controller.

[0040] During the discharge process of the battery pack in the energy storage station cabinet 1, the water pump in the integrated water chiller 3 draws water and passes it through the water supply pipe 31, the first branch pipe 311, the water cooling plate 2, the second branch pipe 321, and the return pipe 32, so that the cooling water circulates in the water cooling plate 2, carrying away the heat generated during the discharge process of the battery pack. The integrated water chiller 3 can cool the returning cooling water, achieving the technical effect of circulating cooling to cool the batteries in the battery compartment.

[0041] By setting up a water immersion sensor, when the water supply pipe 31, return pipe 32, first branch pipe 311 or second branch pipe 321 in cabinet 1 leaks, and the leaked cooling water comes into contact with the water leakage sensing rope 4, the controller of the water immersion sensor controls the buzzer to sound an alarm, prompting the on-site operator that the cooling water in cabinet 1 is leaking.

[0042] It should be noted that in the embodiments of this application, the wireless water immersion sensor with model number FST100-2113 and the integrated water chiller 3 with model number XFlex are used. Both of them are existing technologies and will not be described in detail here.

[0043] Reference Figure 2 , Figure 4Several first carriers 15 and several second carriers 16 are fixedly connected to the two inner side walls opposite to each other in the first mounting cavity. The axial direction of the first carriers 15 and the second carriers 16 is horizontally arranged along the depth direction of the cabinet 1, and the first carriers 15 and the second carriers 16 are opposite each other.

[0044] Mounting plates 21 are fixedly connected to the left and right sides of the water-cooled plate 2, respectively. Mounting seats 17 are fixedly installed at the bottom of the first carrier 15 and the second carrier 16. Slots 171 that are compatible with the mounting plates 21 are opened on the opposite side of the two mounting seats 17, and the two mounting plates 21 can be detachably installed in the two slots 171. The first carrier 15, the second carrier 16 and the mounting seats 17 are all arranged along the depth direction of the cabinet 1.

[0045] The battery pack can be installed in the battery compartment through the first carrier 15 and the second carrier 16 respectively. The water cooling plate 2 can be installed under the battery pack through the two mounting seats 17 under the first carrier 15 and the second carrier 16, so as to facilitate the cooling of the battery pack through the water cooling plate 2.

[0046] Reference Figure 5 The mounting base 17 has an axially upward mounting groove 172, and several rollers 173 are rotatably mounted in the mounting groove 172. A baffle 174 is fixedly connected to the mounting base 17. The baffle 174 is located above the groove opening of the mounting groove 172, and several clearance holes are opened through the baffle 174 to allow the rollers 173 to partially extend.

[0047] With the roller 173 in place, when the operator slides the mounting plates 21 on both sides of the water-cooled plate 2 into or out of the slot 171, the roller 173 rotates at the bottom of the mounting plate 21, which can improve the convenience of the operator in installing or removing the water-cooled plate 2.

[0048] In this embodiment, a limiting protrusion is fixedly connected to the top of the mounting plate 21, and a limiting groove adapted to the limiting protrusion is provided on the top inner wall of the slot 171. The limiting groove is arranged along the axial direction of the mounting base 17, and the limiting protrusion is embedded in the limiting groove.

[0049] The positioning protrusions can further limit the position of the mounting plate 21 and the water-cooled plate 2, thereby improving the stability of the water-cooled plate 2 mounting structure.

[0050] It should be noted that in this embodiment, the surface of the water-cooled plate 2 is coated with an anti-condensation coating. This anti-condensation coating reduces the likelihood of moisture in the air condensing on the surface of the water-cooled plate 2.

[0051] Reference Figure 1 and Figure 2The cabinet 1 includes a back panel, and through holes are provided on both sides of the second mounting cavity on the back panel and the second cabinet door 12. Two mounting frames 18 are fixedly installed on the inner wall of the second mounting cavity. A set of downwardly inclined shielding blades 19 are fixedly connected to the mounting frames 18. The two sets of shielding blades 19 shield the front and rear sides of the integrated water chiller 3 respectively.

[0052] The ventilation requirements of the integrated chiller can be met through the through holes on the back panel and the second cabinet door 12. At the same time, the shielding blades 19 can reduce the occurrence of rainwater entering the cabinet 1 through the through holes.

[0053] The implementation principle of a distributed photovoltaic power generation energy storage station according to an embodiment of this application is as follows: During the discharge process of the battery pack in the energy storage station cabinet 1, the water pump in the integrated water chiller 3 draws water and passes it through the water supply pipe 31, the first branch pipe 311, the water cooling plate 2, the second branch pipe 321, and the return pipe 32, so that the cooling water circulates in the water cooling plate 2, carrying away the heat generated during the discharge process of the battery pack. The integrated water chiller 3 can cool the returning cooling water, achieving the technical effect of circulating cooling to cool the batteries in the battery compartment.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
