Description

Technical Field

[0001] The present invention relates to the technical field of energy storage equipment, and in particular to an energy storage power station and a system thereof capable of reducing losses. Background Art

[0002] An energy storage power station is a power facility that can store electrical energy and release the stored electrical energy when needed. It is like a large "electricity reservoir" that can store electrical energy when there is an oversupply of electricity and release it when there is a peak in electricity demand or insufficient power supply, thereby playing a role in regulating the balance of electricity supply and demand. It consists of an energy storage unit, a power conversion system, a battery management system, and a monitoring and control system.

[0003] Energy storage power stations have different installation requirements in different regions, and the temperatures in different regions are also different. The temperature difference between day and night in some areas is also very large, which will affect the working efficiency of energy storage batteries to a certain extent. Large changes in battery temperature have a significant negative impact on its capacity and charging and discharging efficiency. When the temperature rises, the side reactions inside the battery intensify, which will cause the battery capacity to decay. In a low temperature environment, the viscosity of the battery electrolyte increases, the ion conduction rate decreases, and the internal resistance of the battery increases, which increases the ohmic loss during the charging and discharging process, thereby reducing the battery's charging and discharging efficiency. Repeated temperature changes will also accelerate the aging of internal battery materials, further reducing the effective capacity and overall performance of the battery. Large temperature fluctuations will shorten the cycle life of the battery. High temperature environments may cause structural changes in the positive electrode materials of the battery and lithium plating of the negative electrode materials. Repeated charging and discharging of the battery in a low temperature environment may cause powdering and shedding of the electrode materials. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. During the operation of the energy storage power station, it is necessary to ensure the temperature stability of the energy storage battery. A good thermal management system can maintain the energy storage equipment in a suitable operating temperature range, reduce the battery performance degradation and electromagnetic loss increase caused by overheating, and also reduce the battery performance degradation and electromagnetic loss increase caused by overcooling. According to work needs, the power supply wire is used to drive the heating component or the cooling component to work. The heating component works to heat, and the cooling component works to cool. The power is transmitted to the inner insulation shell through multiple heat dissipation fins, affecting the energy storage components in the energy storage battery. The insulation measures can maintain the energy storage battery in a suitable operating temperature range. The performance of most energy storage batteries is best within a certain temperature range. Good insulation can reduce the performance degradation caused by temperature changes, and ensure that the battery can still maintain a relatively stable output power and energy efficiency at low temperatures. Through insulation, the temperature change amplitude of the battery during the charging and discharging process can be reduced, and the battery damage caused by thermal stress and material performance changes can be reduced, thereby extending the battery cycle life.

[0016] 2. Under normal circumstances, data is transmitted through the control box to the transmission harness in the first protective casing, and then transmitted to the energy storage battery through the transmission harness to achieve data transmission and energy regulation. Under abnormal circumstances, data can be transmitted to the side mounting plate and the transmission harness in the third protective casing through an additional control box, and then transmitted to the energy storage battery through the transmission harness to achieve transmission and energy regulation. In the event of a failure in the main system, the secondary system can quickly take over the control of the energy storage battery. The main system may fail due to power fluctuations, electromagnetic interference and other factors. At this time, the secondary system immediately intervenes to ensure that the energy storage battery continues to charge and discharge stably, maintain the frequency and voltage stability of the power grid, and avoid power supply interruptions due to system failures, greatly improving the reliability of the entire energy storage system under complex working conditions.

[0017] 3. The connection connector is driven down by the operation of lowering the lifting buckle, and when the connection connector is lowered, it is driven to be separated from the energy storage battery. According to the required disconnection operation, after the corresponding energy storage battery is damaged, the electric push rods corresponding to the second protective sleeve and the third protective sleeve are adjusted, or the electric push rod corresponding to the first protective sleeve is adjusted to ensure the separation of the connection connector and the interface on the energy storage battery. Automatically removing the power interface can prevent the device from being overloaded due to long-term connection to the power supply. When the internal circuit of the device fails, resulting in an abnormal increase in current, if the power interface cannot be automatically disconnected, the electronic components inside the device may be damaged due to excessive current. Automatically removing the power interface can cut off the power supply in time to avoid such overload damage and protect the hardware integrity of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The locking bolt 7 is threadedly connected to the side mounting plate 6 to achieve the fixing effect of the top protective cover 5 and the energy storage battery 3 at the connection position, thereby ensuring the connection between the top protective cover 5 and the energy storage battery 3. The top protective cover 5 is arranged on the top of the energy storage battery 3, and the top protective cover 5 fully surrounds the top of the energy storage battery 3, so as to better protect the top of the energy storage battery 3.

They are used to affect the temperature of the inner insulation shell 8 and ensure that the inner insulation shell 8 is working at a constant temperature. The tops of the heating component 12 and the cooling component 13 are provided with power supply wires 14. The power supply wires 14 are used to supply power to the heating component 12 and the cooling component 13 to ensure that the heating component 12 and the cooling component 13 work separately under different circumstances.

The cooling component 13 can be a semiconductor refrigeration component. Based on the Peltier effect, when direct current passes through a galvanic couple composed of two different semiconductor materials, heat absorption and heat release phenomena will occur at both ends of the galvanic couple respectively.

[0037] The second protective sleeve 16 and the third protective sleeve 17 are connected at their connection positions, ensuring normal installation of the backup line.

[0038] Two groups of electric push rods 18 are fixedly installed at the bottom of the energy storage battery 3, and a transverse connecting rod 19 is arranged at the bottom end of each group of electric push rods 18 for connection.

The connecting connector 24 is movably engaged with the lifting buckle 22. The electric push rod 18 drives the transverse connecting rod 19 and the fixed mounting seat 20 to rise and fall. The lifting and falling of the transverse connecting rod 19 and the fixed mounting seat 20 drives the transverse mounting frame 21 to rise and fall. When the transverse mounting frame 21 is lifted and lowered, the lifting buckle 22 and the connecting connector 24 are driven to rise and fall. The connecting connector 24 separates the transmission harness 23 from the energy storage battery 3 to realize the power-off operation.

[0039] The two lifting buckles 22 are arranged symmetrically on the left and right, and the design of the lifting buckles 22 is reasonable.

[0040] The connecting connector 24 is fixedly mounted on the end of the transmission harness 23 , and a certain gap is left between the connecting connector 24 and the bottom of the energy storage battery 3 .

[0041] An interface corresponding to the connecting connector 24 is provided at a position corresponding to the connecting connector 24 at the bottom of the energy storage battery 3 , and the power-on operation is achieved by docking the connecting connector 24 with the bottom structure of the energy storage battery 3 .

[0043] Working principle: During the operation of the energy storage power station, it is necessary to ensure the temperature stability of the energy storage battery 3 during operation. A good thermal management system can maintain the energy storage equipment within a suitable operating temperature range, reduce the battery performance degradation and electromagnetic loss increase caused by overheating, and also reduce the battery performance degradation and electromagnetic loss increase caused by overcooling. According to work needs, the power supply wire 14 is used to power the heating component 12 or the cooling component 13 to work, the heating component 12 works for heating, and the cooling component 13 works for cooling. The temperature influence generated by the operation of the heating component 12 and the cooling component 13 is transmitted to the heat dissipation fins 11 through the lower protective tube 10, and then transmitted to the inner insulation shell 8 through multiple heat dissipation fins 11, and then affects the energy storage components in the energy storage battery 3 through the inner insulation shell 8. The heating component 12 and the cooling component 13 are driven to rotate by the output shaft of the stepper motor 15. The heating component 12 and the cooling component 13 can work at different angles to adjust the influence on the inner insulation shell 8.

[0044] Under normal circumstances, data is transmitted through the control box 2 to the transmission harness 23 in the first protective sleeve 4, and then transmitted to the energy storage battery 3 through the transmission harness 23 to achieve data transmission and energy regulation. Under abnormal circumstances, data can be transmitted through an additional control box 2 to the side mounting plate 6 and the transmission harness 23 in the third protective sleeve 17, and then transmitted to the energy storage battery 3 through the transmission harness 23 to achieve transmission and energy regulation, ensuring that the energy storage battery 3 can still work normally when the main line is damaged, thereby ensuring the working effect of the power station.

[0045] The piston rod of the electric push rod 18 drives the transverse connecting rod 19 and the fixed mounting seat 20 to rise and fall. When the transverse connecting rod 19 descends, it drives the transverse mounting frame 21 and the lifting buckle 22 to descend. The lowering operation of the lifting buckle 22 drives the connecting joint 24 to descend. When the connecting joint 24 descends, it drives the connecting joint 24 to be separated from the energy storage battery 3. According to the required disconnection operation, the electric push rod 18 corresponding to the second protective sleeve 16 and the third protective sleeve 17 is adjusted, or the electric push rod 18 corresponding to the first protective sleeve 4 is adjusted, so as to ensure the separation of the connecting joint 24 and the interface on the energy storage battery 3. After the corresponding energy storage battery 3 is damaged, the transmission harness 23 is separated from the energy storage battery 3 to ensure that the energy storage battery 3 at this position will not affect the normal operation of other energy storage batteries 3.

[0046] The main transmission system is used for the transmission of current and data, and is controlled by the main control assembly, and further controlled by the energy storage system assembly. After the main control assembly is damaged, the current and data are transmitted through the backup transmission system and controlled by the backup control assembly. The temperature control system is used to ensure the temperature inside the energy storage battery 3, and is controlled by the drive system. The energy storage station protection system is used to protect the energy storage battery, and is protected by a protection device, which is specifically a current isolating device or a power-off related component.
