Description

Technical Field

[0001] This invention relates to the field of electrochemical energy storage technology, specifically to a station-type energy storage power station. Background Technology

[0002] Energy storage power stations are power supply facilities that store surplus electricity from the power grid during off-peak periods and then feed it back into the grid during peak periods to alleviate power shortages. Energy storage power stations not only contribute to the safety and stability of the power grid but also ensure power supply for users during critical moments when dealing with extreme weather events. When using electrochemical energy storage, the insulation performance is poor because it mainly consists of single-layer outdoor prefabricated cabins. Since the optimal ambient temperature for battery charging and discharging is around 25 degrees Celsius, many technologies use air conditioning or electric heaters for heating to protect battery life. This requires a large number of air conditioners or electric heaters, resulting in significant energy consumption. However, even with the air conditioning constantly running, it is difficult to maintain the required ambient temperature for battery charging and discharging within the prefabricated cabin, leading to poor heating efficiency.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The station-type energy storage power station 200 of this invention includes multiple battery compartments 1 and heating components 2. The multiple battery compartments 1 are divided into multiple battery compartment groups, and the multiple battery compartment groups are connected in a first direction (e.g., ...). Figure 1 The cells are arranged at intervals in the left-right direction (as shown), and each group of cell clusters includes multiple cells in the second direction (e.g., in the left-right direction). Figure 1 The battery compartments 1 are connected sequentially in the front-back direction (as shown), and the second direction is orthogonal to the first direction. The heating assembly 2 includes a heating interlayer 21 and a heating element 22. One end of the heating interlayer 21 is connected to one of the two adjacent battery compartments 1 in the second direction, and the other end of the heating interlayer 21 is connected to the other battery compartment 1 in the two adjacent battery compartments 1 in the second direction. The heating element 22 is disposed in the heating interlayer 21.

[0025] Specifically, such as Figures 1-3 As shown, multiple battery compartments 1 are arranged at intervals in the left-right direction to form multiple battery compartment groups. Each battery compartment group includes multiple battery compartments 1 connected sequentially in the front-back direction. In the front-back direction, a heating component 2 is provided between two adjacent battery compartment groups. That is, the front end of the heating interlayer 21 is connected to the rear end of the battery compartment 1 located at the front end, and the rear end of the heating interlayer 21 is connected to the front end of the battery compartment 1 located at the rear end. A heating element 22 is provided in the heating interlayer 21. The heating element 22 is connected to a hot water source to provide heat to heat the battery compartment 1. By grouping multiple battery compartments 1 and arranging each battery compartment group, the space of the energy storage power station 200 can be better utilized.

[0026] Optionally, the rear end of the foremost battery chamber 1 in each battery chamber group is connected to the heating interlayer 21, the front end of the rearmost battery chamber 1 in each battery chamber group is connected to the heating interlayer 21, and both the front and rear ends of the battery chambers 1 located between the foremost and rearmost battery chambers 1 are connected to the heating interlayer 21. This ensures that each battery chamber 1 has at least one end connected to the heating interlayer 21, guaranteeing that the heating element 22 can heat the battery chamber 1. When only one end of a battery chamber 1 is connected to the heating interlayer 21, the hot water flow rate entering the heating element 22 within the heating interlayer 21 can be increased to ensure that the indoor temperature of the foremost or rearmost battery chamber 1 reaches the required ambient temperature. Batteries are placed inside battery compartment 1. The required ambient temperature for charging and discharging batteries is around 25 degrees Celsius. Heating interlayer 21 is placed between adjacent battery compartments 1 so that one heating interlayer 21 can provide heat to two battery compartments 1. In each group of battery compartments, the middle battery compartment 1 can be provided with heat by two heating interlayers 21, thereby improving the heating effect of battery compartment 1.

[0027] The station-type energy storage power station 200 of this invention employs multiple battery compartments spaced apart in the left-right direction, and a heating interlayer 21 is provided between two adjacent battery compartments 1 in the front-back direction. Heat is provided to the battery compartments 1 through heating components 22 within the heating interlayer 21. Since the batteries housed in the battery compartments 1 are considered electrical equipment rooms, this embodiment uses a heating interlayer 21 and heating components 22 within it to heat the battery compartments 1, thus ensuring that the heating pipes 23 cannot be located in the electrical equipment room. The heating method, which connects the heating element 22 in the heating interlayer 21 to the hot water supply of the thermal power plant 100, meets the requirements of not installing open flame heating or pressurized hot water pipes in the battery room 1. Heat is transferred to the battery room 1 through the heating interlayer 21, the walls of the battery room 1, and air to complete heat exchange. By utilizing the waste heat from the centralized heating of the nearby thermal power plant 100 in winter, it not only replaces the installation and use of air conditioners and electric heaters, but also achieves better heating effect, saves energy, and has better economic efficiency.

[0028] In some embodiments, the heating assembly 2 further includes a heating pipe 23, one end of which is adapted to be connected to the heating pipe 110 of the thermal power plant 100, and the other end of which is connected to the heating element 22.

[0029] Specifically, the left end of the heating pipe 23 is connected to the heating component 22, and the right end of the heating pipe 23 is connected to the heating pipe 110 of the thermal power plant 100. The hot water in the heating pipe 110 of the thermal power plant 100 is introduced into the heating component 22 to provide heat through the installation of the heating pipe 23.

[0030] In some embodiments, the heating assembly 2 further includes a regulating valve (not shown in the figure), one end of which is connected to the heating pipe 23, and the other end of which is connected to the heating element 22 to adjust the water flow rate entering the heating element 22.

[0031] Specifically, each heating component 2 is equipped with a regulating valve, which controls the flow rate of each heating component 22 to ensure that the temperature in each battery compartment 1 is maintained between 15-30 degrees Celsius. Since the hot water temperature of the power plant can reach over 100 degrees Celsius, and since the temperature of the hot water in the heating pipe 110 is uncontrollable, this embodiment of the invention controls the flow rate of the hot water flowing into the heating component in the heating pipe 23 by setting regulating valves, thereby regulating the temperature in the battery compartment 1 to ensure that the temperature in the battery compartment 1 matches the required ambient temperature, improving the charging and discharging efficiency of the battery, and thus improving the energy storage efficiency of the energy storage power station 200.

[0032] For example, if heating component 2 malfunctions, electric heaters can be used temporarily to provide warmth, ensuring the normal operation of battery compartment 1.

[0033] In some embodiments, the station-type energy storage power station 200 further includes a connecting part 3, one end of which is connected to one of two adjacent battery compartment groups in the first direction, and the other end of which is connected to the other battery compartment group in the first direction.

[0034] Specifically, the left end of the connecting part 3 is connected to the right end of the battery compartment group on the left side, and the right end of the connecting part 3 is connected to the left end of the battery compartment group on the right side. The connecting part 3 connects the battery compartment groups on the left and right sides into a whole, reducing heat loss and improving the heating effect of the heating component on the battery compartment 1.

[0035] In some embodiments, there are multiple connecting parts 3, which are arranged at intervals in the second direction. Two adjacent connecting parts 3 are sequentially connected to two adjacent battery compartment groups to form a communicating space 4.

[0036] Specifically, when there are multiple connecting parts 3, the multiple connecting parts 3 are arranged at intervals in the front-to-back direction. When there are two connecting parts 3, the left end of the connecting part 3 at the front end is connected to the front right end of the left battery compartment group, the right end of the connecting part 3 at the front end is connected to the front left end of the right battery compartment group, the left end of the connecting part 3 at the rear end is connected to the rear right end of the left battery compartment group, and the right end of the connecting part 3 at the rear end is connected to the rear left end of the right battery compartment group. The front connecting part 3 is connected to the front end of the left and right battery compartment groups, and the rear connecting part 3 is connected to the rear end of the left and right battery compartment groups, forming a connecting space 4, which further reduces heat loss and improves the heating effect of the heating component 2.

[0037] Furthermore, the connection part 3 facilitates the entry of staff into each battery compartment 1 for maintenance.

[0038] In some embodiments, the station-type energy storage power station 200 further includes an entrance door 5, which is disposed on the connecting part 3. The entrance door 5 has a first position and a second position. In the first position, the entrance door 5 connects to the outside world and the connecting space 4. In the second position, the entrance door 5 closes the connecting space 4.

[0039] Specifically, such as Figure 1 As shown, the entrance door 5 is mounted on the connecting part 3 and is pivotally connected to the connecting part 3. The entrance door 5 can rotate relative to the connecting part 3 in the up-down direction. When the entrance door 5 is in the first position, the entrance door 5 is open, and staff can enter the connecting space 4 from the outside. When the entrance door 5 is in the second position, the entrance door 5 is closed and the connecting space 4 is closed, reducing the heat exchange between the connecting space 4 and the outside and improving the heating effect of the heating component 2 on the battery room 1.

[0040] In some embodiments, the battery compartment 1 is provided with an interior door 11, which is located at one end of the battery compartment 1 in a first direction. The interior door 11 can connect the battery compartment 1 with the communicating space 4, or the interior door 11 can close the battery compartment 1.

[0041] Specifically, the interior door 11 of the battery compartment 1 on the left is located at the right end, and the interior door 11 of the battery compartment 1 on the right is located at the left end. By arranging the interior doors 11 adjacent to the connecting space 4, it is convenient for staff to enter the connecting space 4 from the entrance door 5 and then enter each battery compartment 1 through the interior door 11. The interior door 11 is pivotally connected to the wall of the battery compartment 1 and can move vertically relative to the wall of the battery compartment 1. When the interior door 11 is open, staff can enter the battery compartment 1 from the connecting space 4. When the interior door 11 is closed and seals the battery compartment 1, it reduces heat exchange between the battery compartment 1 and the connecting space 4, ensuring the insulation effect of the battery compartment 1.

[0042] In some embodiments, the battery compartment 1 and the heating interlayer 21 are both made of reinforced concrete, and the heating pipe 23 is an underground heating pipe 23.

[0043] Specifically, both the battery compartment 1 and the heating interlayer 21 are made of reinforced concrete, and an insulation layer is set on the outside of the battery compartment 1 to achieve the form of reinforced concrete structure and insulation layer. Its insulation performance is much higher than that of prefabricated compartments, making it more suitable for use in cold regions. Furthermore, the use of air conditioning is effectively reduced through centralized heating, which greatly saves energy.

[0044] Furthermore, in this embodiment of the invention, the heating pipe 23 is introduced underground into the heating interlayer 21 of the energy storage power station 200 to reduce heat loss. Moreover, the urban heating pipe 110 is generally a buried pipe, which facilitates pipe connection.

[0045] In some embodiments, the battery compartment 1 is provided with an access port 12 at one end in the second direction, and the access port 12 can connect the battery compartment 1 with the heating interlayer 21.

[0046] Specifically, such as Figure 1 As shown, a maintenance port 12 is provided at the rear end of the battery compartment 1, which facilitates the entry of staff into the heating interlayer 21 for maintenance work.

[0047] In some embodiments, the battery compartment 1 is also provided with an observation port 13, which is arranged adjacent to the maintenance port 12 to observe the operating status of the heating element 22.

[0048] Specifically, the observation port 13 is also located at the rear end of the battery compartment 1. The observation port 13 and the maintenance port 12 are located on the same wall of the battery compartment 1, which facilitates timely observation and maintenance. The setting of the observation port 13 facilitates daily observation of the operating status of the heating components 22 in the heating interlayer 21. For example, it allows for observation of the operating status of the heating components 22, whether the heating components 22 and heating pipes 23 are leaking, etc. The observation port 13 can be a standard viewing window, and the setting of the observation port 13 also facilitates heat transfer.
