Description

Technical Field

[0001] The present invention relates to the technical field of test platforms, and in particular to a simulation test platform for a multifunctional liquid-cooled energy storage system. Background Art

[0002] With the increasing popularity of new energy vehicles, emergency power supply vehicles have emerged. These vehicles can provide power to new energy vehicles that break down due to power shortages. These emergency power supply vehicles are equipped with a container housing an energy storage system for powering new energy vehicles. Existing energy storage systems primarily rely on air cooling, which has low heat dissipation efficiency. Liquid-cooled energy storage systems offer significantly higher heat dissipation efficiency than air-cooled systems. Liquid-cooled energy storage systems include a battery, which includes a housing containing a coolant and several battery cells immersed in the coolant. During operation, the energy storage system must minimize temperature differences between different areas of the coolant to ensure consistent degradation of the cells. Furthermore, since the energy storage system must be installed in a container, the cells must be shock-resistant, meaning their position within the housing will not shift due to vibration. Therefore, for some designed batteries, a simulation test platform is used to test the temperature uniformity of the coolant within the housing and the shock resistance of the battery. The existing test platform has a single function, that is, it can only test a certain performance of the battery. In order to test the battery, it is often necessary to go through multiple test platforms, and the test steps are cumbersome. Summary of the Invention

[0003] In order to solve the shortcomings of the existing test platform with single function and complicated test steps, the present invention proposes a multifunctional simulation test platform for liquid-cooled energy storage system, which can test the temperature uniformity of the coolant and the shock resistance of the battery, and the test steps are convenient.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A simulation test platform for a multifunctional liquid-cooled energy storage system includes a vibration table for supporting a battery of the energy storage system and a vibration device for driving the vibration table to move up and down. The battery includes a shell, and a plurality of battery cells are arranged in the shell. The battery cells are gap-fitted and a heat dissipation space is formed around the battery cells. A positive electrode and a negative electrode are arranged at the upper end of the battery cell. The battery cells are connected in series through conductive sheets to form an energy storage component. A first terminal and a second terminal are arranged on the upper side of the shell. The positive electrode at one end of the energy storage component is electrically connected to the first terminal, and the negative electrode at the other end of the energy storage component is electrically connected to the second terminal. A limiting groove is provided at the bottom of the shell, and the lower end of the battery cell is inserted into the limiting groove. Coolant is provided in the shell, and the battery cell is immersed in the coolant. The upper side of the shell is provided with A first through-hole and several second through-holes are provided, the first through-hole is arranged on the upper side of the heat dissipation space, the second through-hole is arranged on the upper side of the positive pole, a sliding seat is provided on the upper side of the shell, and several temperature probes extending vertically are fixedly connected to the lower side of the sliding seat, the temperature probes are provided on the upper side of the first through-hole and correspond one-to-one with the first through-holes, and the number of temperature probes is consistent with the number of second through-holes and corresponds one-to-one, the temperature probes are electrically connected to a voltmeter, and the end of the voltmeter away from the temperature probe is electrically connected to the second terminal, the sliding seat is slidably connected to a lifting seat, the lifting seat is provided with a first driving device for driving the sliding seat to move horizontally and move the temperature probe to above the second through-hole, and a second driving device for driving the lifting seat to move up and down is provided above the shell.

[0006] The vibration table is used to place the battery to be tested. The upper end of the battery cell to be tested in this application is gap-fitted with the upper side of the housing, and the housing is substantially filled with coolant, that is, the coolant fills the heat dissipation space, and the coolant level is higher than the battery cell, thereby facilitating heat dissipation from the upper end of the battery cell. The conductive sheet and the battery cell are arranged at intervals, and the number of conductive sheets is one less than the number of battery cells. The conductive sheet connects the battery cells in series, that is, one end of the conductive sheet is electrically connected to the negative electrode of the battery cell located on one side of the conductive sheet, and the other end of the conductive sheet is connected to the positive electrode of the battery cell located on the other side of the conductive sheet. At this point, the battery cells and the conductive sheet are connected in series to form an energy storage component. One end of the energy storage component is provided with a positive electrode that is not connected to the conductive sheet and is electrically connected to the first terminal, and the other end is provided with a negative electrode that is not connected to the conductive sheet and is electrically connected to the second terminal. In actual use, the battery cell releases electrical energy outward through the first terminal and the second terminal. The first via and the second via are holes formed on the upper side of the housing for testing.

[0007] During the test, the battery is fixed on the upper side of the vibration table. Specifically, a clamp for clamping the battery can be provided on the upper side of the vibration table, and the battery is fixed on the upper side of the vibration table by the clamp. The battery cell then releases electrical energy outward through the first terminal and the second terminal to simulate the state of the energy storage system during operation. At this time, the temperature of the battery cell and the coolant rises. After one hour, the battery cell stops discharging, and then the lifting seat moves downward under the action of the second drive device and drives the temperature probe downward. The temperature probe passes downward through the first via and is inserted into the heat dissipation space to measure the temperature of multiple areas of the coolant. When the maximum temperature difference obtained by each temperature probe is less than 2 degrees Celsius, it means that the coolant temperature uniformity is qualified, otherwise it is unqualified. After the temperature measurement of the temperature probe is completed, under the action of the lifting seat, the temperature probe moves upward and leaves the first via. At this point, the present application completes the test of coolant temperature uniformity.

[0008] Next, the battery's shock resistance is tested. The cell position detection step begins, verifying that the battery cells are initially properly installed within the housing. Specifically, the first drive mechanism drives the sliding seat along the lifting seat until the temperature probes are directly above the second vias. The second drive mechanism then drives the temperature probes downward, passing through the second vias and approaching the positive electrodes. When the lower ends of each temperature probe simultaneously contact the corresponding positive electrode, the battery cell is properly installed. Conversely, if the lower ends of some temperature probes contact the corresponding positive electrode while others do not, it indicates that a cell is not properly installed and requires further testing. When a temperature probe contacts the corresponding positive electrode, a circuit is formed between the temperature probe, the positive electrode, the second terminal, and the voltmeter, and the corresponding voltmeter displays a voltage value. Conversely, when the temperature probes do not contact the corresponding positive electrode, the temperature probes and the positive electrode are disconnected, and the corresponding voltmeter displays a voltage value of zero. Through the above settings, it is possible to know which temperature probes are in contact with the positive electrode and which temperature probes are disconnected from the positive electrode by observing the voltmeter.

[0009] After the battery in the initial state is tested and all the battery cells are installed in place. The temperature probe moves upward under the action of the second driving device and leaves the second via. Then, under the action of the vibration device, the vibration table and the battery vibrate up and down. After 10 minutes of vibration, the vibration table stops vibrating, and then the battery cell position detection step is performed again. If the battery cells are still installed in place at this time, the battery's seismic performance is qualified. Otherwise, the battery's seismic performance is unqualified, that is, some battery cells move upward under the action of vibration and disengage from the bottom of the limit slot. At this point, this application completes the battery's seismic resistance test.

[0010] Furthermore, a sealing rubber sheet is provided in each of the first through hole and the second through hole, and the sealing rubber sheet is provided with pinholes.

[0011] The provision of a sealing rubber sheet allows less heat from the battery case to escape through the first and second vias during discharge, improving test accuracy. Furthermore, the pinhole is initially closed. When the temperature probe passes through the first via, it penetrates the pinhole and opens it. The sealing rubber sheet allows less heat from the case to escape through the gap between the first via and the temperature probe. Once the temperature probe leaves the first via, the pinhole recloses due to the elasticity of the material.

[0012] Furthermore, the simulation test platform includes a first reference plane and a second reference plane, both of which extend horizontally, the upper side of the positive electrode is located on the first reference plane, and the lower end of the temperature probe is located on the second reference plane.

[0013] Furthermore, the energy storage system also includes a cooling device for cooling the coolant, the cooling device includes a condenser, the condenser is arranged in the shell and immersed in the coolant, the cooling device also includes a compressor, the compressor is connected to a connecting pipe, and the connecting pipe passes through the shell and is connected to the condenser.

[0014] This application is applicable to the testing of energy storage systems with cooling devices. Freon is installed in the connecting pipe and condenser tube. After the compressor is running, the Freon lowers the temperature of the condenser tube, thereby lowering the temperature of the coolant in the shell. When testing the seismic performance of the battery, the battery moves up and down, while the compressor does not vibrate because it is not installed on a vibration table. The connecting pipe is long and has good elasticity. At this time, the end of the connecting pipe close to the shell moves up and down with the shell, while the end of the connecting pipe close to the compressor does not move up and down.

[0015] Furthermore, the vibration device includes a guide rod fixedly connected to the lower side of the vibration table and extending vertically. A base is provided on the lower side of the vibration table. A guide sleeve is fixedly connected to the upper side of the base. A slide groove opening upward is formed in the guide sleeve. The lower end of the guide rod is slidably connected in the slide groove. The guide rod and the bottom of the slide groove are connected by a spring. A motor is fixedly connected to the upper side of the base. The motor is connected to a cam. The upper side of the cam abuts against the lower side of the vibration table.

[0016] The motor is used to drive the cam to rotate, and the spring makes the lower side of the vibration table always abut against the upper side of the cam. When the cam rotates, the vibration table moves up and down, and the setting of the guide sleeve and guide rod makes the movement of the vibration table more stable.

[0017] Furthermore, the first driving device includes a first electric cylinder fixedly connected to the lifting seat, and the output shaft of the first electric cylinder is connected to the sliding seat.

[0018] The first electric cylinder can be purchased directly from the market, which facilitates the maintenance and production of this application.

[0019] Furthermore, the second driving device is a second electric cylinder, and the lower end of the second electric cylinder is connected to the lifting seat.

[0020] The second electric cylinder can be purchased directly from the market, which facilitates the maintenance and production of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 6A multifunctional liquid-cooled energy storage system simulation test platform includes a vibration table 21 for supporting a battery 11 of the energy storage system and a vibration device 22 for driving the vibration table 21 to move up and down. The battery 11 includes a housing 111, and a plurality of battery cells 112 are arranged in the housing 111. The battery cells 112 are fitted with gaps to form a heat dissipation space around the battery cells 112. The upper ends of the battery cells 112 are provided with a positive electrode 1121 and a negative electrode 1122. The battery cells 112 are connected in series through conductive sheets 1123. And form an energy storage component, the upper side of the shell 111 is provided with a first terminal 113 and a second terminal 114, the positive electrode 1121 at one end of the energy storage component is electrically connected to the first terminal 113, and the negative electrode 1122 at the other end of the energy storage component is electrically connected to the second terminal 114, the bottom of the shell 111 is provided with a limiting groove 1111, the lower end of the battery cell 112 is inserted into the limiting groove 1111, the shell 111 is provided with a coolant, the battery cell 112 is immersed in the coolant, and the upper side of the shell 111 A plurality of first through holes 1112 and a plurality of second through holes 1113 are provided. The first through holes 1112 are provided on the upper side of the heat dissipation space, and the second through holes 1113 are provided on the upper side of the positive electrode 1121. A sliding seat 23 is provided on the upper side of the shell 111. A plurality of temperature probes 24 extending vertically are fixedly connected to the lower side of the sliding seat 23. The temperature probes 24 are provided on the upper side of the first through holes 1112 and correspond one-to-one with the first through holes 1112. The number of the temperature probes 24 is consistent with the number of the second through holes 1113 and corresponds one-to-one. The temperature probes 24 are all electrically connected to a voltmeter 25. The end of the voltmeter 25 away from the temperature probe 24 is electrically connected to the second terminal 114. The sliding seat 23 is slidably connected to a lifting seat 231. The lifting seat 231 is provided with a first driving device 26 for driving the sliding seat 23 to move horizontally and move the temperature probe 24 to above the second through hole 1113. A second driving device 27 for driving the lifting seat 231 to move up and down is provided above the shell 111.

[0029] The simulation test platform includes a first reference plane 201 and a second reference plane 202 . The first reference plane 201 and the second reference plane 202 both extend horizontally. The upper side of the positive electrode 1121 is located on the first reference plane 201 , and the lower end of the temperature probe 24 is located on the second reference plane 202 .

[0030] The vibration table 21 is used to place the battery 11 to be tested. The upper end of the battery cell 112 of the battery 11 to be tested in this application is gap-fitted with the upper side of the shell 111, and the shell 111 is basically filled with coolant, that is, the coolant fills the heat dissipation space, and the liquid level of the coolant is higher than the battery cell 112, so as to facilitate heat dissipation from the upper end of the battery cell 112. The conductive sheet 1123 and the battery cell 112 are arranged at intervals, and the number of conductive sheets 1123 is one less than the number of battery cells 112. The conductive sheet 1123 connects the battery cells 112 in series, that is, one end of the conductive sheet 1123 is electrically connected to the negative electrode 1122 of the battery cell 112 located on one side of the conductive sheet 1123, and the other end of the conductive sheet 1123 is connected to the positive electrode 1121 of the battery cell 112 located on the other side of the conductive sheet 1123. At this point, the battery cell 112 and the conductive sheet 1123 are connected in series to form an energy storage assembly. One end of the energy storage assembly is provided with a positive electrode 1121 that is not connected to the conductive sheet 1123 and is electrically connected to the first terminal 113. The other end is provided with a negative electrode 1122 that is not connected to the conductive sheet 1123 and is electrically connected to the second terminal 114. In actual use, the battery cell 112 releases electrical energy to the outside through the first terminal 113 and the second terminal 114. The first via 1112 and the second via 1113 are holes formed on the upper side of the housing 111 for testing purposes.

[0031] See also Figure 3 During the test, the battery 11 is fixed to the upper side of the vibration table 21. Specifically, a clamp for holding the battery 11 can be provided on the upper side of the vibration table 21, and the battery 11 is fixed to the upper side of the vibration table 21 by the clamp. The battery cell 112 then releases electrical energy outward through the first terminal 113 and the second terminal 114, thereby simulating the state of the energy storage system during operation. At this time, the temperature of the battery cell 112 and the coolant increases. After one hour, the battery cell 112 stops discharging. The lifting base 231 then moves downward under the action of the second driving device 27 and drives the temperature probe 24 downward. The temperature probe 24 passes downward through the first through-hole 1112 and is inserted into the heat dissipation space. The temperature of multiple areas of the coolant is measured. When the maximum temperature difference obtained by each temperature probe 24 is less than 2 degrees Celsius, it means that the coolant temperature uniformity is qualified; otherwise, it is unqualified. After the temperature probe 24 completes the temperature measurement, the temperature probe 24 moves upward under the action of the lifting base 231 and leaves the first through-hole 1112. At this point, the application completes the test of coolant temperature uniformity.

[0032] Next, we begin to test the shock resistance of the battery 11, and first perform the battery cell 112 position detection step, which is used to verify whether the battery cell 112 of the battery 11 in the initial state is installed in place inside the shell 111. The battery cell 112 position detection step is specifically as follows: first, under the action of the first driving device 26, the sliding seat 23 is driven to move along the lifting seat 231 until the temperature probe 24 moves to just above the second through hole 1113, and then the second driving device 27 drives the temperature probe 24 to move downward, and the temperature probe 24 passes through the second through hole 1113 and approaches the positive electrode 1121. When the lower end of each temperature probe 24 contacts the corresponding positive electrode 1121 at the same time, it means that the upper side of the positive electrode is located on the first reference plane 201, which means that the battery cell 112 is installed in place, see Figure 4 On the contrary, when the lower end of a temperature probe 24 abuts the corresponding positive electrode 1121, the other temperature probes 24 have not yet abutted the corresponding positive electrode 1121, which means that the upper side of some positive electrodes is not at the first reference plane, that is, the battery cell 112 is not installed in place, and the battery cell 112 needs to be installed in place before subsequent testing. Figure 6 When the temperature probe 24 abuts the corresponding positive electrode 1121, a circuit is formed between the temperature probe 24, the positive electrode 1121, the second terminal 114, and the voltmeter 25, and the corresponding voltmeter 25 will display the voltage value. Conversely, when the temperature probe 24 is not abutting the corresponding positive electrode 1121, the temperature probe 24 and the positive electrode 1121 are disconnected, and the voltage value of the corresponding voltmeter 25 is zero. With this configuration, by observing the voltmeter 25, it is possible to determine which temperature probes 24 are abutting the positive electrode 1121 and which are disconnected.

[0033] After the battery 11 in the initial state is tested and all the cells 112 are installed in place, the temperature probe 24 moves upward under the action of the second driving device 27 and leaves the second through hole 1113. Then, under the action of the vibration device 22, the vibration table 21 and the battery 11 vibrate up and down, see Figure 5 After 10 minutes of vibration, the vibration table 21 stops vibrating, and then the battery cell 112 position detection step is performed again. If the battery cell 112 is still installed in place at this time, the shock resistance of the battery 11 is qualified. Otherwise, the shock resistance of the battery 11 is unqualified, that is, some of the battery cells 112 move upward under the action of vibration and disengage from the bottom of the limit groove 1111. Figure 6 At this point, the present application completes the test of the shock resistance of the battery 11.

[0034] A sealing rubber sheet 1114 is disposed in each of the first through hole 1112 and the second through hole 1113 . The sealing rubber sheet 1114 is provided with a pinhole 1115 .

[0035] The provision of sealing rubber sheet 1114 allows less heat from the housing 111 to escape through first via 1112 and second via 1113 during discharge of the battery cell 112, thereby increasing test accuracy. Furthermore, pinhole 1115 is initially closed. When temperature probe 24 passes through first via 1112, it penetrates pinhole 1115 and opens it. At this point, sealing rubber sheet 1114 allows less heat from the housing 111 to escape through the gap between first via 1112 and temperature probe 24. When temperature probe 24 leaves first via 1112, pinhole 1115 recloses due to the elasticity of the material.

[0036] The energy storage system also includes a cooling device 12 for cooling the coolant. The cooling device 12 includes a condenser 121. The condenser 121 is arranged in the shell 111 and immersed in the coolant. The cooling device 12 also includes a compressor 122. The compressor 122 is connected to a connecting pipe 123. The connecting pipe 123 passes through the shell 111 and is connected to the condenser 121.

[0037] The present application is applicable to the testing of energy storage systems with cooling devices 12. Freon is provided in the connecting pipe 123 and the condensing pipe 121. After the compressor 122 is running, the Freon lowers the temperature of the condensing pipe 121, thereby lowering the temperature of the coolant in the shell 111. When testing the anti-seismic performance of the battery 11, the battery 11 moves up and down, while the compressor 122 does not vibrate because it is not set on the vibration table 21. The length of the connecting pipe 123 is longer, making the connecting pipe 123 easier to bend and having better elasticity. At this time, the end of the connecting pipe 123 close to the shell 111 moves up and down with the shell 111, while the end of the connecting pipe 123 close to the compressor 122 does not move up and down.

[0038] The vibration device 22 includes a guide rod 221 fixedly connected to the lower side of the vibration table 21 and extending vertically. A base 222 is provided on the lower side of the vibration table 21. A guide sleeve 223 is fixedly connected to the upper side of the base 222. A slide groove 2231 opening upward is formed in the guide sleeve 223. The lower end of the guide rod 221 is slidably connected in the slide groove 2231. The guide rod 221 and the bottom of the slide groove 2231 are connected by a spring 224. A motor 225 is fixedly connected to the upper side of the base 222. The motor 225 is connected to a cam 226. The upper side of the cam 226 abuts against the lower side of the vibration table 21.

[0039] The motor 225 is used to drive the cam 226 to rotate, and the spring 224 ensures that the lower side of the vibration table 21 is always in contact with the upper side of the cam 226. When the cam 226 rotates, the vibration table 21 moves up and down, and the setting of the guide sleeve 223 and the guide rod 221 makes the movement of the vibration table 21 more stable.

[0040] The first driving device 26 includes a first electric cylinder fixedly connected to the lifting seat 231 , and an output shaft of the first electric cylinder is connected to the sliding seat 23 .

[0041] The first electric cylinder can be purchased directly from the market, which facilitates the maintenance and production of this application.

[0042] The second driving device 27 is a second electric cylinder, and the lower end of the second electric cylinder is connected to the lifting seat 231 .

[0043] The second electric cylinder can be purchased directly from the market, which facilitates the maintenance and production of this application.

[0044] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
