Description

Technical Field

[0001] This invention relates to the field of battery pack technology, and more specifically to a remote discharge capacity assessment device for battery packs. Background Technology

[0002] Battery banks are independent and reliable power sources, unaffected by AC power. Even in the event of an accident within a power plant or substation, or a complete AC power outage, they ensure reliable and continuous operation of equipment in the DC system with stable voltage. They also serve as emergency lighting power for the entire plant or substation, acting as the last line of defense to ensure uninterrupted power supply. Discharge capacity verification is a core aspect of battery maintenance. Discharge tests verify the actual capacity and performance of the battery, ensuring its reliability within the power system. Discharge capacity verification technology, through optimized solutions (such as DC / DC boost), strict parameter standards, and intelligent system design, solves the problems of low efficiency and high risk associated with traditional methods, providing crucial assurance for power system stability. Future directions will focus on the deep integration of remote automation and energy recycling. Remote discharge capacity verification devices for battery banks are power equipment operation and maintenance systems integrating remote control, data acquisition, intelligent analysis, and energy saving. They are mainly used for battery status monitoring and capacity verification in substations, communication base stations, and other scenarios. (Patent: CN 213658935) A battery pack capacity discharge device disclosed in the present invention includes a first load and a second load, which are connected by a DC bus. A first circuit breaker is installed on the DC bus, dividing the DC bus into a first bus near the first load and a second bus near the second load. A first converter and a first battery pack are electrically connected to the first bus, and a second converter and a second battery pack are connected to the second bus. A third converter is electrically connected between the first battery pack and the second battery pack. The battery pack capacity discharge device of the present invention is simple to operate, reduces workload, and lowers labor costs.

[0003] Existing battery pack discharge capacity assessment devices on the market have relatively simple structures and lack the ability to remotely control capacity discharge and monitor the temperature of each battery in the battery pack. Traditional battery pack discharge capacity assessment devices make battery assembly and disassembly inconvenient, hindering battery pack maintenance and battery replacement. They cannot provide various types of specialized heat dissipation based on the degree of battery temperature rise, lack the ability to protect individual batteries from overheating, and do not have the ability to automatically explode and detach overheated batteries. Overheating and combustion of batteries in the battery pack can easily spread.

[0004] To address the aforementioned problems, this invention proposes a remote discharge capacity verification device for battery packs. Summary of the Invention

[0019] (3) Beneficial effects:

[0020] A. This remote discharge capacity assessment device for the battery pack facilitates battery pack assembly. During later maintenance, the electric push rod is controlled to move the pressure plate away from the slider. Under the action of the first spring, the mounting plate moves upward and pops out with the cooperation of the slider and the slide groove, which facilitates the replacement and maintenance of each battery in the battery pack. The mobile terminal, together with the remote control module, can remotely control the capacity assessment and discharge of the battery pack. Through the data transmission module, the user can remotely obtain the temperature of each battery in the battery pack through the mobile terminal. Through the battery temperature detection and analysis module, the temperature of each battery in the battery pack can be detected and analyzed. According to the degree of battery temperature rise, the water-cooled clamping component and the overheat protection component are controlled to work respectively, which is conducive to the comprehensive protection of each battery in the battery pack.

[0021] B. The battery locking assembly enables the locking connection between the battery terminals and the connectors, facilitating the assembly of the battery pack. During the upward movement and ejection of the mounting plate and battery, the connectors on the support plate move upwards accordingly. Tightening the pull rope during this process releases the pressure of the cone block on the terminal post, thereby releasing the locking between the terminal post and the locking hole. This disengages the battery terminals and connectors, allowing for direct removal of the battery and facilitating the disassembly of the battery pack. This also makes battery pack maintenance and battery replacement easier.

[0022] C. With the water-cooled clamping assembly, after the mounting plate and battery are inserted into the housing mounting slot, the liquid pump can be controlled to pump the coolant in the liquid tank. The pumped coolant is respectively input into the first liquid bladder, the second liquid bladder and the hollow interior of the mounting plate. The liquid bladders on both sides of the side plate expand to clamp the battery on one side of the mounting plate, which serves to clamp and fix the battery inserted into the housing. The first liquid bladder, the second liquid bladder and the hollow interior of the mounting plate are filled with coolant. The coolant absorbs the heat generated by the battery operation. After absorbing heat, the coolant flows back to the interior of the liquid tank through the radiator, realizing the function of circulating water cooling heat dissipation of each battery in the battery pack.

[0023] D. Through the setting of overheat protection components, during the use of the battery pack, the temperature sensor in the mounting slot monitors the temperature of each battery in the battery pack. The electrical control box monitors and analyzes the temperature of each battery. When the battery temperature is detected to be too high, the electrical control box controls the corresponding electrical control valve to open. The liquid nitrogen gas in the liquid nitrogen tank is discharged through the gas pipe joint, gas outlet pipe and gas supply pipe at the corresponding third branch pipe. The discharged liquid nitrogen gas is input into the air bag and sprayed out through the air blowing pipes on both sides to provide special heat dissipation for the electrode posts on both sides of the battery, which plays the role of special overheat protection for each battery in the battery pack.

[0024] E. Through the coordinated arrangement of the battery locking assembly and the overheat protection assembly, during the process of the mounting plate and battery being moved upward and ejected under the action of the first spring, the terminals on the support plate are moved upward accordingly. During this process, the pull rope is tightened, and the pull knot at the middle end of the pull rope tightens the air blowing pipes on both sides. In conjunction with the operation of the overheat protection assembly, liquid nitrogen gas is input into the airbag and cannot be discharged through the air blowing pipes at both ends. The airbag expands and explodes, which can rupture and separate the overheated battery that has been ejected upward, effectively preventing the spread of overheating and combustion of the battery pack.

Mounting grooves 2 are distributed on the top outer wall of the housing 1. A mounting plate 3 is mounted on one side of the outer wall of the mounting groove 2. A slider 4 is fixed on one side of the outer wall of the mounting plate 3. A sliding groove 5 is formed on one side of the inner wall of the mounting groove 2, and the slider 4 is engaged inside the sliding groove 5. A first spring 6 is distributed and fixed on the bottom inner wall of the sliding groove 5. A support plate 7 is fixed on one side of the bottom outer wall of the mounting plate 3. Side plates 8 are symmetrically fixed on both ends of one side of the mounting plate 3. A battery 9 is inserted between the side plates 8 and placed above the support plate 7. Electrode posts 91 are provided on the top two sides of the outer wall of the battery 9. On the top two outer walls of the support plate 7, corresponding to the electrode posts 91, terminal posts 10 are embedded and fixed. A folded wire frame 11 is rotatably installed between the bottom outer wall of one side of the mounting plate 3 and the bottom inner wall of the mounting groove 2, and the folded wire frame 11 is located below the terminal post 10. A main line through groove 12 is opened through the bottom inner walls of the mounting groove 2, and an electric push rod 13 is installed on the outer wall of the outer shell 1 of the main line through groove 12 located on the top side of the mounting groove 2.

A battery locking assembly 16 is provided on the top inner wall of the terminal post 10. Side plate 8 Water-cooled clamping components 17 are provided on both inner walls of the casing 1, and overheat protection components 18 are provided on the bottom inner wall of the mounting slot 2. The battery pack remote discharge capacity applicator completes the assembly of the battery pack by inserting batteries 9 into each mounting slot 2 of the casing 1. During the assembly process, the batteries 9 are inverted and placed on the support plate 7 at the bottom of the mounting plate 3. The electrode posts 91 at the bottom of the batteries 9 and the terminals 10 on the support plate 7 are snapped together, and a branch power line is connected to the bottom of the terminal 10. The branch power line passes through the folded wire frame 11 and is connected to the main power line of the battery pack at the main line through slot 12. The main power line passes through the casing 1 from the main line through slot 12 for subsequent storage. The external wiring of the battery pack is inserted into the mounting slot 2 by pressing the mounting plate 3 and moving it downwards in cooperation with the slider 4 and the slide groove 5. During the process, the slider 4 moves downwards and compresses the first spring 6. After the mounting plate 3 and the battery 9 are inserted, the electric push rod 13 is controlled to drive the pressure plate 14 to move laterally, so that the pressure plate 14 is above the slider 4, thus fixing the mounting plate 3 after insertion. This structure facilitates the assembly of the battery pack. During later maintenance, the electric push rod 13 is controlled to move the pressure plate 14 away from the slider 4. Under the action of the first spring 6, the mounting plate 3 moves upwards and pops out in cooperation with the slider 4 and the slide groove 5, which facilitates the replacement and maintenance of each battery 9 in the battery pack.

[0045] In this embodiment, refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 9As shown, the battery latching assembly 16 includes an insertion hole 161 on the outer wall of the end of the electrode post 91. An inner groove 162 is formed on the inner wall of the end of the terminal post 10. Through holes 163 are formed on the inner walls on both sides of the end of the inner groove 162. An end post 164 is inserted into the through hole 163. A limit block 165 is fixed to one end of the end post 164 inside the inner groove 162. A second spring 166 is fitted onto the outer wall of the end post 164 on one side of the limit block 165. A cone block 167 is provided inside the inner groove 162. A third spring 168 is provided on the inner wall of the inner groove 162 on one side of the cone block 167. The electrode post 91 is located in the inner groove 162. A through hole 169 is provided on one side of the inner wall. A pull rope 1610 is fixed on one side of the outer wall of the cone block 167. One end of the pull rope 1610 passes through the third spring 168 and extends through the outside of the through hole 169. The other end of the pull rope 1610 is fixed to the bottom inner wall of the mounting groove 2. A locking hole 1611 is provided on both sides of the inner wall of the insertion hole 161 to the end post 164. During the process of the battery 9 being inverted above the support plate 7, the bottom electrode post 91 of the battery 9 is aligned with the terminal post 10. Pressing the battery 9 causes the top of the terminal post 10 to be inserted into the insertion hole 161 at the bottom of the electrode post 91. During the insertion process, the end post 164 is compressed and contracted to the through hole. Inside hole 163, the limiting block 165 at the end of the end post 164 presses against the cone block 167 inside the inner groove 162. During the inclined extrusion process, the cone block 167 moves downward, compressing the third spring 168. When the terminal post 10 is inserted into the insertion hole 161 and the end post 164 and the locking hole 1611 are aligned, the cone block 167 is reset and moved upward under the action of the third spring 168. The cone block 167 pushes the end post 164 out of the through hole 163, causing the end post 164 to be locked into the locking hole 1611, realizing the locking connection between the battery 9 electrode post 91 and the terminal post 10, which facilitates the assembly of the battery pack battery 9. The above is the first spring During the upward ejection process driven by the spring 6, the mounting plate 3 and battery 9 are moved upward, and the terminal 10 on the support plate 7 moves upward accordingly. During this process, the pull rope 1610 is tightened, and the pull rope 1610 drives the cone block 167 to move downward in the inner groove 162, releasing the pressure of the cone block 167 on the end post 164. Under the action of the second spring 166, the end post 164 is driven to reset and retract in the through hole 163, thereby releasing the jamming between the end post 164 and the locking hole 1611, realizing the release of the jamming connection between the battery 9 electrode post 91 and the terminal 10. The battery pack can be disassembled by directly removing the battery 9, which facilitates the maintenance of the battery pack and the replacement of the battery 9.

The pumped coolant is input into the pump end pipe 173, then into the first liquid bladder 174 through each of the first branch pipes 176, then into the hollow interior of the mounting plate 3 through the first bend pipe 178, and then into the second liquid bladder 175 through the second bend pipe 179. Under the action of the pressure relief valve 1711, the first liquid bladder 174 and the second liquid bladder 175 are filled and expanded by the continuous pumping. The liquid on both sides of the side plate 8... The expansion of the bladder clamps the battery 9 on one side of the mounting plate 3, thus securing the battery 9 inserted into the casing 1. The first liquid bladder 174, the second liquid bladder 175, and the hollow interior of the mounting plate 3 are filled with coolant. The coolant absorbs the heat generated by the battery 9 during operation. After absorbing heat, the coolant is input into the return end pipe 1712 through the second branch pipe 1710, and then into the radiator 1714 through the return pipe 1713. The coolant undergoes heat exchange in the radiator 1714, allowing the absorbed heat to be radiated out. After dissipation, the coolant flows back into the liquid tank 171, realizing the function of circulating water cooling for each battery 9 in the battery pack.

[0047] Furthermore, both the first branch pipe 176 and the second branch pipe 1710 are telescopic hoses, which allow the first branch pipe 176 and the second branch pipe 1710 to extend and retract during the insertion and lifting of the mounting plate 3, ensuring the injection of liquid into the first branch pipe 176 and the second branch pipe 1710.

The liquid nitrogen gas in the liquid nitrogen tank 185 is discharged through the air pipe joint 186, the air outlet pipe 187 and the air supply pipe 183 at the corresponding third branch pipe 182. The discharged liquid nitrogen gas is input into the air bag 189 and sprayed out through the air blowing pipes 1810 on both sides to perform special heat dissipation on the electrode posts 91 on both sides of the battery 9, which plays the role of special overheat protection for each battery 9 in the battery pack.

[0049] Furthermore, the air blowing pipe 1810 is a flexible hose, and the middle end of the pull rope 1610 is tied with a pull knot on the outer wall of the end of the air blowing pipe 1810. During the process of the mounting plate 3 and battery 9 being moved upward and ejected under the action of the first spring 6, the terminal 10 on the support plate 7 moves upward accordingly, and the pull rope 1610 is tightened during the process. The pull knot at the middle end of the pull rope 1610 tightens the air blowing pipe 1810 twice. In conjunction with the operation of the overheat protection component 18, liquid nitrogen gas is input into the airbag 189 and cannot be discharged through the air blowing pipes 1810 at both ends. The airbag 189 is inflated and explodes, which can rupture and peel off the overheated battery that has been moved upward and ejected, effectively preventing the spread of overheating and combustion of the battery pack.

[0050] Furthermore, the third branch pipe 182 is a telescopic hose, which allows the third branch pipe 182 to extend and retract during the insertion and lifting of the mounting plate 3, ensuring the air injection of the third branch pipe 182.

[0051] Furthermore, a circuit board 151 is fixed on the bottom inner wall of the electrical control box 15. A PLC controller 152 and a power module 153 are installed on the top outer wall of the circuit board 151. A capacitor discharge module 154 and a remote control module 155 are distributed on the top outer wall of the circuit board 151. A data acquisition module 156 and a data transmission module 157 are distributed on the other top outer wall of the circuit board 151. A mobile terminal 19 is installed outside the electrical control box 15. The output terminal of the temperature sensor 181 is electrically connected to the input terminal of the data acquisition module 156. A battery temperature detection and analysis module 158 is installed on the wall. During the use of the battery pack, the mobile terminal 19, together with the remote control module 155, can remotely control the discharge of the battery pack. Through the data transmission module 157, the user can remotely obtain the temperature of each battery in the battery pack through the mobile terminal 19. Through the battery temperature detection and analysis module 158, the temperature of each battery 9 in the battery pack can be detected and analyzed. According to the degree of temperature rise of the battery 9, the water-cooling clamping component 17 and the overheat protection component 18 are controlled to work respectively, which is conducive to the comprehensive protection of each battery 9 in the battery pack.

[0052] Furthermore, a water-cooled clamping drive module 159 is installed on the top outer wall of the circuit board 151. The electrical output terminal of the water-cooled clamping drive module 159 is connected to the electrical input terminal of the liquid pump 172. The water-cooled clamping drive module 159 drives the water-cooled clamping assembly 17 by controlling the operation of the liquid pump 172.

[0053] Furthermore, an overheat protection module 1510 and an insertion ejection control module 1511 are installed on the top outer wall of the circuit board 151. The electrical output terminal of the overheat protection module 1510 is connected to the electrical control valve 188 and the electrical input terminal of the insertion ejection control module 1511. The electrical output terminal of the insertion ejection control module 1511 is connected to the electrical input terminal of the electric push rod 13. During the use of the battery pack, when the battery temperature detection and analysis module 158 detects that the battery 9 is overheated, the overheat protection module 1510 controls the electrical control valve 188 to open, so that liquid nitrogen is discharged to quickly cool the battery 9, and controls the electric push rod 13 to work so that the pressure plate 14 moves away from the slider 4. Under the action of the first spring 6, the mounting plate 3 and the battery 9 move upward and eject.

[0054] Working Principle: In use, the remote discharge capacity assessment device for this battery pack completes the assembly of the battery pack by inserting batteries 9 into the mounting slots 2 of the outer casing 1. During the assembly process, the batteries 9 are inverted and placed on the support plate 7 at the bottom of the mounting plate 3, with the bottom electrode post 91 of the battery 9 aligned above the terminal post 10. The battery 9 is pressed so that the top of the terminal post 10 is inserted into the insertion hole 161 at the bottom of the electrode post 91. During the insertion process, the end post 164 is squeezed and retracted into the through hole 163. The limiting block 165 at the end of the end post 164 squeezes the cone block 167 inside the inner groove 162. During the inclined extrusion process, the cone block 167 is driven to move downward, compressing the third spring 168. The end post 164 and the locking hole 1 are then inserted into the insertion hole 161 of the terminal post 10. When aligning at 611, the cone block 167 is reset and moved upward under the action of the third spring 168. The cone block 167 pushes the end post 164 out of the through hole 163, so that the end post 164 is snapped into the snap hole 1611, realizing the snap connection between the battery 9 electrode post 91 and the terminal post 10, which facilitates the assembly of the battery 9 in the battery pack. A branch power line is connected to the bottom of the terminal post 10, and the branch power line passes through the folded wire frame 11. The branch power line is connected to the main power line of the battery pack at the main line through groove 12. The main power line passes out of the outer shell 1 from the main line through groove 12 for subsequent external wiring of the battery pack. By pressing the mounting plate 3, it is moved downward and inserted into the mounting groove 2 under the cooperation of the slider 4 and the sliding groove 5. During the process, the slider 4 moves downward and compresses the first After the spring 6, mounting plate 3, and battery 9 are inserted, the electric push rod 13 is controlled to move the pressure plate 14 laterally, positioning it above the slider 4. This secures the mounting plate 3 after insertion, facilitating battery pack assembly. During later maintenance, the electric push rod 13 moves the pressure plate 14 away from the slider 4. Under the action of the first spring 6, the mounting plate 3 moves upward and pops out with the cooperation of the slider 4 and the slide groove 5. The terminal 10 on the support plate 7 moves upward accordingly. During this process, the pull rope 1610 is tightened, causing the cone 167 to move downward within the inner groove 162, relieving the pressure of the cone 167 on the end post 164. Under the action of the second spring 166, the end post 164 retracts and resets within the through hole 163. This releases the locking mechanism between the end post 164 and the locking hole 1611, thus disengaging the battery 9 electrode post 91 and the terminal post 10. The battery 9 can then be directly removed to complete the disassembly of the battery pack, facilitating the maintenance of the battery pack and the replacement of the battery 9. During the use of this battery pack, the mobile terminal 19, in conjunction with the remote control module 155, can remotely control the full-capacity discharge of the battery pack. Through the data transmission module 157, the user can remotely acquire the temperature of each battery in the battery pack via the mobile terminal 19. Through the battery temperature detection and analysis module 158, the temperature of each battery 9 in the battery pack can be detected and analyzed. Based on the degree of temperature rise of the battery 9, the water-cooled clamping assembly 17 and the overheat protection assembly 18 are controlled to work respectively.The water-cooled clamping drive module 159 controls the liquid pump 172 to pump coolant from the liquid tank 171. The pumped coolant is fed into the pump end pipe 173, then into the first liquid bladder 174 through each of the first branch pipes 176, then into the hollow interior of the mounting plate 3 through the first bend pipe 178, and finally into the second liquid bladder 175 through the second bend pipe 179. Continuous pumping, under the action of the pressure relief valve 1711, causes the first and second liquid bladders 174 and 175 to expand. The expansion of the liquid bladders on both sides of the side plate 8 clamps the battery 9 on one side of the mounting plate 3, thus... The battery 9 is inserted into the casing 1 and clamped in place. The first liquid bladder 174, the second liquid bladder 175, and the mounting plate 3 are hollow and filled with coolant. The coolant absorbs the heat generated by the battery 9 during operation. After absorbing heat, the coolant is fed into the return pipe 1712 through the second branch pipe 1710 and into the radiator 1714 through the return pipe 1713. The coolant undergoes heat exchange in the radiator 1714, allowing the absorbed heat to be radiated out. The cooled coolant then flows back into the liquid tank 171, realizing the connection between the individual batteries 9 in the battery pack. The function of circulating water cooling: When the battery temperature detection and analysis module 158 detects that the battery 9 is overheating, the overheat protection module 1510 controls the electronic control valve 188 to open. The liquid nitrogen gas in the liquid nitrogen tank 185 is discharged through the gas pipe joint 186, the gas outlet pipe 187 and the gas supply pipe 183 at the corresponding third branch pipe 182. The discharged liquid nitrogen gas is input into the air bag 189 and sprayed out through the air blowing pipes 1810 on both sides to specifically dissipate heat from the electrode posts 91 on both sides of the battery 9, thus playing a specific overheat protection role for each battery 9 in the battery pack; the above During the upward ejection process of the mounting plate 3 and battery 9 driven by the first spring 6, the terminal 10 on the support plate 7 also moves upward, tightening the pull rope 1610. The pull knot at the middle end of the pull rope 1610 tightens the two air blowing pipes 1810. In conjunction with the overheat protection component 18, liquid nitrogen gas entering the airbag 189 cannot be discharged through the air blowing pipes 1810 at both ends. The airbag 189 expands and explodes, effectively detaching the upward-ejected overheated battery and preventing the spread of overheating and combustion of the battery pack.
