Description

Technical Field

[0001] The present invention belongs to the technical field of battery testing, and more specifically, relates to a device for predicting the service life of energy storage batteries. Background Art

[0002] An energy storage battery is a device that stores electrical energy and releases it when needed, and is widely used in new energy power generation, electric vehicles, power grid peak shaving and other fields. Its core is to achieve charge and discharge through electrochemical reactions. However, after long-term use, the battery performance will gradually decay, mainly manifested as a decrease in capacity (i.e., less stored electrical energy) and an increase in internal resistance (affecting charge and discharge efficiency). Therefore, it is very necessary to accurately predict the service life of energy storage batteries.

[0003] In the prior art, when predicting the service life of a battery, it is necessary to conduct charge and discharge experiments on multiple sample batteries to obtain experimental data of multiple charge and discharge cycles of each sample battery, and obtain the aging characteristic data of the sample batteries by conducting charge and discharge experiments on multiple sample batteries. However, in the actual use process of the battery, due to different external environments, the degree of aging and energy decline is also different. For example, a battery installed in a car is often affected by the movement and various bumps of the car, and external factors such as movement and bumps will cause uneven distribution of the electrolyte inside the battery, and the life of the battery will be affected accordingly. The prior art cannot predict the service life of the battery in different environments, and there are obvious limitations, resulting in a large gap between the predicted life result and the actual situation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a device for predicting the service life of an energy storage battery that can overcome or at least partially solve the above problems.

[0006] Preferably, the driving part includes a driving motor fixedly installed on the base, a ring frame is fixedly connected to the lower end of the support column, a ring gear is fixedly installed at the lower end of the ring frame, and a driving gear meshing with the ring gear is fixedly installed on the output shaft of the driving motor.

[0007] Preferably, the pushing component includes a reciprocating lead screw rotatably connected to the outer wall of the support column. The reciprocating lead screw is arranged parallel to the cross bar. A reciprocating slide is mounted on the outer wall of the reciprocating lead screw and is slidably connected to the cross bar. The storage box is fixedly connected to the reciprocating slide. A linkage part for driving the reciprocating lead screw to rotate is provided on the base.

[0008] Further, the linkage part includes a driven gear fixedly installed at the end of the reciprocating lead screw. An annular cover is fixedly connected to the base. An annular plate is fixedly connected to the upper port of the annular cover. A plurality of arc-shaped racks distributed circumferentially are fixedly installed on the annular plate. When the reciprocating lead screw rotates following the support column, the driven gear will engage with the plurality of arc-shaped racks in sequence.

[0009] Preferably, a transfer column is fixedly connected to the base. The support column rotates on the transfer column. A plurality of battery detectors are fixedly installed around the transfer column. The connecting wires of the battery detectors extend into the transfer column. A wire extending into the support column is fixedly connected to the storage box. The wire and the connecting wire are connected through a connecting component.

[0010] Preferably, a longitudinal groove is provided at the inner bottom of the storage box. A lifting block is longitudinally slidably installed in the longitudinal groove. A hollow box located inside the storage box is installed on the top of the lifting block. An inner cover plate is installed in the opening of the hollow box. A shaking part for driving the lifting block to move up and down is provided on the support column.

[0011] Further, the shaking part includes an upper convex block fixedly connected to the bottom of the lifting block. A disc is fixedly connected to the outer wall of the support column. The upper convex block is attached to the upper end face of the disc. A plurality of lower convex blocks arranged at equal intervals are fixedly connected to the upper end face of the disc. A limiting plate is fixedly connected to the top of the lifting block. A spring is installed between the limiting plate and the inner bottom of the storage box.

[0012] Further, a short shaft deviating from the center of gravity is fixedly connected to the bottom of the hollow box. The short shaft is rotatably installed at the top of the lifting block.

[0013] Further, an L-shaped bracket is fixedly connected to the outer wall of the support column. The end of the reciprocating lead screw away from the support column is rotatably connected to the L-shaped bracket.

[0014] A method for predicting the service life of energy storage batteries includes the following steps: S1. Repeatedly charge and discharge multiple groups of batteries, and at the same time place the multiple groups of batteries in environments with different temperatures, and detect their service lives; S2. Make the battery continuously revolve around the reference axis to simulate the battery during the moving process; S3. Make the acceleration received by the battery change suddenly from large to small to simulate the battery moving at different speeds; S4. Tilt and deflect the battery intermittently to simulate the turning action of the battery during movement; S5. Continuously vibrate the battery to simulate the vibration effect on the battery during movement, and make the vibration frequency increase as the moving speed of the battery increases.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. In the present invention, the driving motor drives the support column to rotate, and the battery in the hollow box will continuously move, thereby simulating the charging and discharging of the battery during movement. During the prediction process, the temperature control device can also control the temperature in the storage box, thereby simulating the working environment of the battery under high temperature, low temperature and normal temperature conditions, making the battery charging and discharging environment more in line with the actual situation, and making the life prediction result closer to the actual situation.

[0016] 2. In the present invention, the reciprocating lead screw drives the storage box to linearly slide. When the reciprocating sliding table drives the storage box to slide away from the support column, the circumference of the storage box revolving around the support column will increase. Then, the storage box and the battery inside will be subjected to a greater centrifugal force, so that the influence of different speeds on the battery during driving can be simulated. Since there are multiple sections of arc-shaped racks, sudden acceleration and deceleration of the battery can be simulated, such as the sudden acceleration and deceleration of a car, making the battery charging and discharging environment more in line with the actual situation, and further making the life prediction of the battery more accurate.

[0017] 3. In the present invention, when the centrifugal force received by the storage box suddenly becomes larger, the hollow box will deflect and tilt on the lifting block through the short axis. When the centrifugal force on the hollow box and the battery suddenly decreases, the battery and the hollow box will shift to the other side. Therefore, the battery in the hollow box can simulate the force received when the car suddenly turns, making the battery charging and discharging environment more in line with the actual situation, and further improving the prediction accuracy of the battery service life.

[0018] 4. In the present invention, when the upper convex block slides over multiple lower convex blocks, the upper convex block will drive the lifting block to vibrate up and down, and then drive the hollow box and the battery inside to vibrate up and down, thereby simulating the vibration effect on the battery during movement, and cooperating with the sudden acceleration and deceleration effects, making the battery charging and discharging environment more in line with the actual situation, and further making the life prediction of the battery more accurate.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0023] Example 1: Reference Figures 1-9, A prediction device for the service life of an energy storage battery, including a base 1 for supporting the entire device, and further including: a cylindrical support column 2, rotatably connected to the top of the base 1. Among them, a circumferentially distributed cross bar 12 is fixedly connected to the outer wall of the support column 2. The cross bar 12 is perpendicular to the axis of the support column 2. A storage box 3 for storing the battery is slidably installed on the cross bar 12. An outer cover plate 5 for sealing the storage box 3 is installed in the port of the storage box 3. A temperature control device 4 is installed on the storage box 3. The temperature control device 4 can be composed of an electric heating wire for raising the temperature and a semiconductor refrigeration sheet radiator for lowering the temperature, and is evenly distributed on the inner wall of the storage box 3. A driving part for driving the support column 2 to rotate is provided on the base 1. The driving part includes a driving motor 6 fixedly installed on the base 1. The lower end of the support column 2 is fixedly connected with an annular frame 9. The lower end of the annular frame 9 is fixedly installed with an annular gear 8. The output shaft of the driving motor 6 is fixedly installed with a driving gear 7 meshing with the annular gear 8; a pushing component, arranged on the outer wall of the support column 2, and the pushing component is used to drive the storage box 3 to intermittently approach or move away from the support column 2. A cable for charging and discharging the battery is also arranged in the storage box 3, and the end of the cable is connected to a charging and discharging device.

[0024] Specifically, during use, the energy storage battery is fixed in the storage box 3 and charged and discharged. During the charging and discharging test period, the driving motor 6 is turned on. The driving motor 6 will drive the driving gear 7 to rotate. The driving gear 7 will drive the annular frame 9 to rotate through the annular gear 8. The annular frame 9 will drive the support column 2 to rotate. The support column 2 will drive the storage box 3 to revolve around the support column 2 through the cross bar 12. The battery in the storage box 3 will move synchronously, so as to simulate the charging and discharging of the battery during the moving process. During the prediction process, the temperature control device 4 can also control the temperature in the storage box 3, so as to simulate the working environment of the battery under high temperature, low temperature and normal temperature, make the charging and discharging environment of the battery more in line with the actual situation, and make the service life prediction result closer to the actual situation.

[0025] Embodiment 2: Refer to Figures 3-5 , A prediction device for the service life of an energy storage battery, which is basically the same as Embodiment 1. Further: The above-mentioned driving component includes a reciprocating lead screw 11 rotatably connected to the outer wall of the support column 2. The reciprocating lead screw 11 is arranged parallel to the cross bar 12. A reciprocating slide 13 slidably connected to the cross bar 12 is installed on the outer wall of the reciprocating lead screw 11. When the reciprocating lead screw 11 rotates continuously, the reciprocating slide 13 will reciprocate along the outer wall of the reciprocating lead screw 11. The storage box 3 is fixedly connected to the reciprocating slide 13. A linkage part for driving the reciprocating lead screw 11 to rotate is provided on the base 1. The linkage part includes a driven gear 15 fixedly installed at the end of the reciprocating lead screw 11. A circular cover 27 is fixedly connected to the base 1. A circular plate 14 is fixedly connected to the upper port of the circular cover 27. A plurality of arc-shaped racks 16 distributed circumferentially are fixedly installed on the circular plate 14. The axis of the arc-shaped rack 16 is collinear with the axis of the support column 2. When the reciprocating lead screw 11 rotates following the support column 2, the driven gear 15 will sequentially engage with the plurality of arc-shaped racks 16. An L-shaped bracket is fixedly connected to the outer wall of the support column 2. One end of the reciprocating lead screw 11 far from the support column 2 is rotatably connected to the L-shaped bracket.

[0026] Specifically, during the continuous rotation of the support column 2, the support column 2 will drive the reciprocating lead screw 11 and the driven gear 15 to rotate synchronously. The driven gear 15 will then continuously roll along the circular plate 14. When the driven gear 15 engages with an arc-shaped rack 16 on the circular plate 14, the arc-shaped rack 16 will drive the reciprocating lead screw 11 to rotate through the driven gear 15. The reciprocating lead screw 11 will drive the reciprocating slide 13 to linearly slide along its outer wall. The reciprocating slide 13 will drive the storage box 3 to linearly slide. When the reciprocating slide 13 slides to the end of the reciprocating lead screw 11, the continuously rotating reciprocating lead screw 11 will drive the reciprocating slide 13 to slide in the reverse direction. When the reciprocating slide 13 drives the storage box 3 to slide away from the support column 2, the circumference of the storage box 3 revolving around the support column 2 will increase. Thus, the storage box 3 and the battery inside will be subjected to a greater centrifugal force, so as to simulate the influence of different speeds on the battery during driving. Since there are multiple arc-shaped racks 16, sudden acceleration and deceleration of the battery can be simulated, such as the sudden acceleration and deceleration of a car, making the battery charge and discharge environment more in line with the actual situation, and further making the prediction of the battery life more accurate.

[0027] Example 3: Refer to Figure 3 、 Figures 6-9 , a device for predicting the service life of an energy storage battery, which is basically the same as that in Example 2. Further: A longitudinal groove 17 is provided at the inner bottom of the above-mentioned storage box 3. A lifting block 18 is longitudinally slidably installed in the longitudinal groove 17. The top of the lifting block 18 is provided with a hollow box 23 located inside the storage box 3. The hollow box 23 is made of stainless steel or copper alloy that is easy to conduct heat, and its outer wall is provided with air holes. During testing, the battery needs to be fixed inside the hollow box 23. There is an active gap between the hollow box 23 and the inner wall of the storage box 3. An inner cover plate 26 for blocking the entrance of the hollow box 23 is installed in the opening of the hollow box 23. A shaking part for driving the lifting block 18 to move up and down is provided on the support column 2. The shaking part includes an upper convex block 21 fixedly connected to the bottom of the lifting block 18. A disc 10 is fixedly connected to the outer wall of the support column 2. The upper convex block 21 fits on the upper end surface of the disc 10. A plurality of lower convex blocks 22 arranged at equal intervals are fixedly connected to the upper end surface of the disc 10. A limiting plate 19 is fixedly connected to the top of the lifting block 18. A spring 20 is installed between the limiting plate 19 and the inner bottom of the storage box 3. The outer shapes of the upper convex block 21 and the lower convex block 22 can both be hemispherical.

[0028] When the storage box 3 revolves around the support column 2, the storage box 3 will also drive the upper convex block 21 at the bottom to slide along the upper surface of the disc 10. When the upper convex block 21 slides above one of the lower convex blocks 22, the upper convex block 21 will be pushed up by the lower convex block 22, and drive the lifting block 18 to slide upward in the longitudinal groove 17, and stretch the spring 20 through the limiting plate 19. When the upper convex block 21 passes over the upper side of the lower convex block 22, the spring 20 is not subjected to the stretching force, so it will elastically reset, and drive the lifting block 18 and the upper convex block 21 to slide downward and reset through the limiting plate 19. Therefore, when the upper convex block 21 slides past a plurality of lower convex blocks 22, the upper convex block 21 will drive the lifting block 18 to shake up and down, and then drive the hollow box 23 and the battery inside to shake up and down, so as to simulate the vibration effect on the battery when it moves, and cooperate with the rapid acceleration and rapid deceleration effects, so that the battery charging and discharging environment is more in line with the actual situation, and further make the battery life prediction more accurate. When the storage box 3 is far away from the support column 2, the revolution path of the storage box 3 around the support column 2 increases. Therefore, the upper convex block 21 will pass over more lower convex blocks 22 in the same time, making the storage box 3 vibrate more violently, so as to simulate that a faster speed will make the car and the battery vibrate more violently, making the battery charging and discharging environment more in line with the actual situation, so that the battery life prediction is more accurate.

[0029] A short shaft 24 deviating from the center of gravity is fixedly connected to the bottom of the above-mentioned hollow box 23, and the short shaft 24 is rotatably installed on the top of the lifting block 18 Specifically, when the storage box 3 suddenly moves away from the support column 2, that is, when the centrifugal force acting on the storage box 3 suddenly increases, since the short axis 24 deviates from the center of gravity of the hollow box 23, the hollow box 23 will deflect under the action of the suddenly increased centrifugal force, that is, it will deflect and tilt on the lifting block 18 through the short axis 24. When the storage box 3 suddenly moves towards the support column 2, the centrifugal forces on the hollow box 23 and the battery will suddenly decrease, and the battery and the hollow box 23 will shift to the other side. Thus, the battery in the hollow box 23 can simulate the force received during a sudden turn of the vehicle, making the battery charging and discharging environment more in line with the actual situation, and further improving the prediction accuracy of the battery service life.

[0030] When the hollow box 23 vibrates up and down and deflects in the storage box 3, the hollow box 23 can disturb the air in the storage box 3. Then, the air heated and cooled by the temperature control device 4 in the storage box 3 can contact the battery more evenly, making the battery heated more evenly, reducing the occurrence of local overheating or overcooling of the battery, and ensuring more accurate prediction of the battery life.

[0031] Embodiment 4: Refer to Figures 1-3 , a prediction device for the service life of a storage battery, which is basically the same as Embodiment 3. Further: A transfer column 28 is fixedly connected to the base 1 described above. The support column 2 rotates on the transfer column 28. A plurality of battery detectors 25 for detecting the battery life are fixedly installed around the transfer column 28. The connecting wires 29 of the battery detectors 25 extend into the transfer column 28. A wire 30 extending into the support column 2 is fixedly connected to the storage box 3. The wire 30 and the connecting wire 29 are connected through a connecting component. The connecting component includes a metal ring 31 fixed in the transfer column 28. A brush 32 elastically pressed against the metal ring 31 is fixedly connected to the support column 2. The wire 30 is fixedly connected to the brush 32, and the connecting wire 29 is fixedly connected to the metal ring 31.

[0032] Specifically, the battery detector 25 is used to detect the service life of the battery in real time, and the connection component is used to connect the battery detector 25 to the battery. It mainly consists of a carbon brush 32 and a metal ring 31. When the support column 2 rotates, it can drive the carbon brush 32 to slide along the metal ring 31, so as to achieve electrical connection during rotation. The specific connection method can refer to the internal structure of a brushed motor. Similarly, the same method can be used for the battery to connect with external charging devices and discharging devices. Since this is not the main problem to be solved in this application, it will not be elaborated here. In practice, at least three storage boxes 3 can be set. The three storage boxes 3 can create high-temperature, low-temperature, and normal-temperature environments respectively. And through the setting of the carbon brush 32 and the metal ring 31, different charging and discharging powers can be provided for the three groups of storage batteries. The simulated scenarios can be more diverse and can be completed at one time. Therefore, the prediction efficiency and accuracy of the battery life can be higher.

[0033] Embodiment 5: Refer to Figures 1-9 , a method for predicting the service life of an energy storage battery, comprising the following steps: S1. Repeatedly charge and discharge multiple groups of batteries, and at the same time place the multiple groups of batteries in environments with different temperatures, and detect their service lives; S2. Make the battery continuously revolve around a reference axis to simulate the battery during movement; S3. Make the acceleration received by the battery vary from large to small to simulate the battery moving at different speeds; S4. Make the battery tilt and deflect intermittently to simulate the battery making turning movements during movement; S5. Make the battery continuously receive vibration effects to simulate the battery receiving vibration effects during movement, and make the vibration frequency increase as the moving speed of the battery increases.

[0034] When the present invention is in use, the energy storage battery is fixed in the hollow box 23 and charged and discharged. During the charging and discharging process, the battery detector 25 is used to detect the service life of the battery in real time. During this period, the driving motor 6 is turned on. The driving motor 6 will drive the driving gear 7 to rotate. The driving gear 7 will drive the annular frame 9 to rotate through the annular gear 8. The annular frame 9 will drive the support column 2 to rotate. The support column 2 will drive the storage box 3 to revolve around the support column 2 through the cross bar 12. The battery in the hollow box 23 will move synchronously, so as to simulate the battery being charged and discharged during movement. During the prediction process, the temperature control device 4 can also control the temperature in the storage box 3, so as to simulate the working environments of the battery under high temperature, low temperature, and normal temperature, make the battery charging and discharging environment more in line with the actual situation, and make the life prediction result closer to the actual situation.

[0035] During the continuous rotation of the support column 2, the support column 2 drives the reciprocating lead screw 11 and the driven gear 15 to rotate synchronously. The driven gear 15 continuously rolls along the annular plate 14. When the driven gear 15 meshes with an arc-shaped rack 16 on the annular plate 14, the arc-shaped rack 16 drives the reciprocating lead screw 11 to rotate through the driven gear 15. The reciprocating lead screw 11 drives the reciprocating slide 13 to linearly slide along its outer wall. The reciprocating slide 13 drives the storage box 3 to linearly slide. When the reciprocating slide 13 slides to the end of the reciprocating lead screw 11, the continuously rotating reciprocating lead screw 11 drives the reciprocating slide 13 to slide in the reverse direction. When the reciprocating slide 13 drives the storage box 3 to slide away from the support column 2, the perimeter of the revolution of the storage box 3 around the support column 2 increases. Thus, the storage box 3 and the internal battery are subjected to a greater centrifugal force, so that the influence of different speeds on the battery during driving can be simulated. Since there are multiple sections of the arc-shaped rack 16, sudden acceleration and deceleration of the battery can be simulated, such as sudden acceleration and sudden deceleration of a car, making the battery charge-discharge environment more in line with the actual situation, and further making the prediction of the battery life more accurate.

[0036] When the storage box 3 revolves around the support column 2, the storage box 3 also drives the upper convex block 21 at the bottom to slide along the upper surface of the disc 10. When the upper convex block 21 slides above one of the lower convex blocks 22, the upper convex block 21 is pushed up by the lower convex block 22 and drives the lifting block 18 to slide upward in the longitudinal groove 17, and stretches the spring 20 through the limiting plate 19. When the upper convex block 21 passes over the upper part of the lower convex block 22, the spring 20 is not subjected to the stretching force, so it will elastically reset and drive the lifting block 18 and the upper convex block 21 to slide downward and reset through the limiting plate 19. Thus, when the upper convex block 21 slides over multiple lower convex blocks 22, the upper convex block 21 drives the lifting block 18 to vibrate up and down, and then drives the hollow box 23 and the internal battery to vibrate up and down, so as to simulate the vibration of the battery during movement, and cooperate with sudden acceleration and sudden deceleration, making the battery charge-discharge environment more in line with the actual situation, and further making the prediction of the battery life more accurate. When the storage box 3 moves away from the support column 2, the revolution path of the storage box 3 around the support column 2 increases. Thus, the upper convex block 21 will pass over more lower convex blocks 22 in the same time, making the vibration of the storage box 3 more intense, so as to simulate that a faster speed will make the car and the battery vibrate more intensely, making the battery charge-discharge environment more in line with the actual situation, and thus making the prediction of the battery life more accurate.

Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
