Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle battery recycling management, and in particular to a new energy vehicle battery recycling management and storage device. Background Art

[0002] With the rapid development of the new energy vehicle industry, the number of retired power batteries has increased dramatically. How to effectively manage and recycle these waste batteries has become an urgent problem to be solved. The new energy vehicle battery recycling management and collection device came into being in this context, aiming to achieve efficient and environmentally friendly recycling and reuse of waste power batteries.

[0003] New energy vehicle power batteries contain a large amount of valuable metals, such as lithium, cobalt, and nickel. These metal resources are limited and the mining cost is high. By recycling and processing waste power batteries, these metal resources can be effectively recovered, reducing dependence on natural resources, reducing production costs, and reducing environmental pollution. Therefore, the development of efficient and intelligent battery recycling management and storage devices has important economic and environmental significance.

[0004] The core technology of the device is to realize the automated collection, classification, storage and transportation of used batteries. By integrating advanced sensors, automated control systems and intelligent identification technology, the device can automatically identify the type, state and residual value of used batteries, and achieve accurate classification and efficient recycling. At the same time, the device is also environmentally friendly and energy-saving, adopting a low-energy consumption and low-emission design to reduce energy consumption and environmental pollution during the recycling process.

[0005] Chinese Patent Publication No.: CN117239277B discloses a new energy vehicle battery recycling management and storage device, which relates to the field of new energy vehicle battery equipment processing technology, including support vertical poles; support horizontal plates, which are installed between four support vertical poles and are equidistantly distributed. The invention has the following beneficial effects: the invention is provided with an auxiliary fill light component and a collection box, and gas recovery and processing is performed through a collection filter plate, and the sliding position of the mounting seat is limited by a slide groove and a second slider when sliding, and fill light processing is performed by a fill light tube; the invention is provided with an auxiliary detection component, which drives the detection probe to move downward until the required height, and when the connecting plate slides downward as a whole, it is limited and buffered by a shock-absorbing damper and a buffer spring, thereby extending the overall service life, and limiting the position by a positioning bolt; the invention is provided with an auxiliary moving component, and solar light resources are recycled and utilized through a solar photovoltaic component, thereby achieving self-sufficiency in electric power resources and saving overall use costs.

[0006] It can be seen that the new energy vehicle battery recycling management and storage device has the following problems: although the invention uses shock-absorbing dampers and buffer springs to limit buffering to improve the operating stability of the equipment for placing new energy vehicle batteries, there is a lack of monitoring of the equipment's operating stability, and the safety of batteries with potential safety hazards during transportation cannot be guaranteed. There is also a lack of monitoring of the battery status when recycling the batteries, which makes it inconvenient to uniformly manage the batteries. Summary of the invention

[0060] and, determining whether the operation stability of the loading module meets the standard based on the acceleration variance in the determined operation mode, and determining whether the flatness of the driving route meets the standard according to the angle based on the condition that the operation stability of the loading module does not meet the standard, and, based on the condition that the flatness of the driving route meets the standard, reducing the preset operation speed of the loading module, or, based on the condition that the flatness of the driving route does not meet the standard, replanning the driving route;

[0061] And, based on the condition that the transportation performance of the loading module does not meet the standards, it is determined to load the recycled batteries with the third level battery risk in the next loading cycle.

[0062] Specifically, the image acquisition unit uses an industrial camera MV-GE800C / M to acquire image information, and the ultrasonic detection unit emits an ultrasonic frequency of 30kHz.

[0063] Specifically, the rolling direction is the direction in which the loading module moves in the longitudinal, transverse, oblique or rotational directions.

[0064] Specifically, the image information includes damaged or dented outer shell, unclear markings, and non-original combination; the structural information includes internal voids, bubbles, insufficient or uneven electrolyte infiltration, internal corrosion of the pole, internal short circuit, battery cell structural defects, and electrolyte leakage.

[0065] Specifically, the score for damaged shell is 5 points, the score for dented shell is 4 points, the score for non-original combination is 3 points, and the score for unclear labeling is 2 points; the score for internal short circuit is 10 points, the score for battery cell structural defects is 8 points, the score for internal voids and bubbles is 6 points, the score for insufficient or uneven electrolyte infiltration is 5 points, the score for internal corrosion of the pole is 4 points, and the score for electrolyte leakage is 3 points.

[0066] Specifically, the safety hazard evaluation value is the sum of the scores corresponding to the external and internal problems of the recycled batteries.

[0067] Specifically, the same risk level priority principle in the embodiment of the present invention is to preferentially load recycled batteries of the same risk level onto one loading module, and then load recycled batteries of other risk levels if the loading module is not full.

[0068] Specifically, the present invention detects and evaluates the surface and internal states of the recycled batteries based on the nondestructive testing module and the risk assessment module to perform risk grading, and transports the recycled batteries to the loading module based on the same risk level priority principle, so as to facilitate the subsequent processing of the recycled batteries and reduce the management complexity of the recycled batteries; the second risk of the loading module is determined based on the first risk ratio, and the operation mode is determined based on the second risk level, and the recycled batteries are transported in an operation mode with stricter stability standards for the loading modules with high second risk levels, and the recycled batteries are transported in an operation mode with lower stability standards for the loading modules with low second risk levels, thereby improving the transportation efficiency; for the first operation mode and the second operation mode, the operation stability is determined based on the acceleration variance, and the instability caused by the uneven driving route or the instability caused by the excessively fast running speed of the loading module is determined based on the angle between the ground and the laser sensor beam, and the operation process is adjusted according to different reasons, thereby improving the monitoring accuracy of the transportation process of the recycled batteries and ensuring the safety of the recycled batteries.

[0069] See also Figure 2 As shown, it is a flow chart of the risk assessment module determining the first risk according to an embodiment of the present invention.

[0070] Specifically, the risk assessment module determines a first risk of a single recycled battery based on the safety hazard evaluation value.

[0071] If the safety hazard evaluation value is greater than a first preset safety hazard evaluation value of 40, the risk assessment module determines that the first risk is a first-level battery risk;

[0072] If the safety hazard evaluation value is less than or equal to the first preset safety hazard evaluation value of 40 and greater than the second preset safety hazard evaluation value of 25, the risk assessment module determines that the first risk is a secondary battery risk;

[0073] If the safety hazard evaluation value is less than or equal to the second preset safety hazard evaluation value 25, the risk assessment module determines that the first risk is a level 3 battery risk;

[0074] Among them, the first-level battery risk>the second-level battery risk>the third-level battery risk.

[0075] Specifically, the present invention evaluates the status of a single recycled battery and determines the risk level through image acquisition and ultrasonic flaw detection, marks the recycled battery for subsequent processing, reduces the management complexity of the recycled battery, thereby improving the monitoring accuracy of the recycled battery transportation process and ensuring the safety of the recycled battery.

[0076] See also Figure 3As shown, it is a flow chart of the risk assessment module determining the second risk according to an embodiment of the present invention.

[0077] Specifically, if the first-level battery risk ratio is greater than 60% of the first preset risk ratio, the risk assessment module determines that the second risk is a first-level loading module risk;

[0078] If the primary battery risk ratio is less than or equal to 60% of the first preset risk ratio and the secondary battery risk ratio is less than or equal to 70% of the second preset risk ratio, or the secondary battery risk ratio is greater than 70% of the second preset risk ratio, the risk assessment module determines that the second risk is a secondary loading module risk;

[0079] If the first-level battery risk ratio is zero and the second-level battery risk ratio is less than or equal to 70% of the second preset risk ratio, the risk assessment module determines that the second risk is a third-level loading module risk;

[0080] Among them, the first-level loading module risk>the second-level loading module risk>the third-level loading module risk.

[0081] See also Figure 4 As shown, it is a flow chart of the central control module determining the operating mode of the loading module according to an embodiment of the present invention.

[0082] Specifically, the central control module determines the operation mode of the loading module based on the second risk.

[0083] If the second risk is the first-level loading module risk, the central control module determines that the operation mode of the loading module is the first operation mode;

[0084] If the second risk is the secondary loading module risk, the central control module determines that the operation mode of the loading module is the second operation mode;

[0085] If the second risk is the third-level loading module risk, the central control module determines that the operation mode of the loading module is the third operation mode.

[0086] Specifically, the preset running speed of the first running mode is 15 m / min, and the detection period of running stability is 30 s; the preset running speed of the second running mode is 25 m / min, and the detection period of running stability is 1 min; the preset running speed of the third running mode is 40 m / min.

[0087] Furthermore, the present invention determines the risk level of the loading module through the first risk ratio, and determines the operation mode based on the risk level of the loading module. The operation speed is slow and the detection cycle is short for a high risk level, which improves the transportation efficiency while ensuring the safety of recycled battery transportation, thereby improving the monitoring accuracy of the recycled battery transportation process.

[0088] Specifically, the central control module determines whether the operation stability of the loading module meets the standard based on the acceleration variance in the first operation mode or the second operation mode.

[0089] If the acceleration variance is greater than a preset acceleration variance, the central control module determines that the operation stability of the loading module does not meet the standard;

[0090] If the acceleration variance is less than or equal to the preset acceleration variance, the central control module determines that the operation stability of the loading module meets the standard.

[0091] Specifically, in the first operating mode, the acceleration variance is preset to be 0.25 m 2 / s 4 , the acceleration variance is preset to 1m in the second operation mode 2 / s 4 .

[0092] Specifically, the present invention sets different preset acceleration variances for the first operating mode and the second operating mode. The smaller the acceleration variance, the higher the requirement for operating stability, thereby improving the monitoring accuracy of operating stability during the transportation process of recycled batteries.

[0093] Specifically, the calculation formula of the acceleration variance is as follows:

[0094]

[0095] Among them, S 2 represents the acceleration variance, n represents the total number of acceleration data, i represents the i-th acceleration data, V i represents acceleration, Indicates the average value of acceleration.

[0096] Specifically, the central control module determines whether the flatness of the driving route meets the standard based on the angle.

[0097] If the angle is greater than a preset angle, the central control module determines that the flatness of the driving route does not meet the standard;

[0098] If the angle is less than or equal to the preset angle, the central control module determines that the flatness of the driving route meets the standard.

[0099] Specifically, the preset angle in the first operating mode is ±0.1°, and the preset angle in the second operating mode is ±0.3°.

[0100] Specifically, the smaller the angle, the flatter the road surface, the more stable the operation process of the loading module, and the higher the safety of the recycled battery.

[0101] Specifically, the central control module determines to reduce the preset operating speed of the loading module under the condition that the flatness of the driving route meets the standard, and sets several adjustment methods for the preset operating speed, and each adjustment method has a different adjustment range for the preset operating speed, and the adjusted preset operating speed is used as the new preset operating speed.

[0102] Specifically, the central control module determines the adjustment method for the preset running speed based on the acceleration variance difference.

[0103] If the acceleration variance difference is greater than the preset difference of 0.3m 2 / s 4 , the central control module uses the first rate adjustment coefficient of 0.85 to adjust the preset operating rate;

[0104] If the acceleration variance difference is less than or equal to the preset difference of 0.3m 2 / s 4 , the central control module uses the first rate adjustment coefficient 0.9 to adjust the preset operating rate.

[0105] Specifically, the central control module determines to re-plan the driving route under the condition that the flatness of the driving route does not meet the standards, divides the area between the starting point and the end point of the recycled battery transportation process into several sub-areas, and detects the angle between the ground and the laser sensor beam in each sub-area, connects the sub-areas whose angle is less than or equal to the preset angle, and selects the shortest route as the new driving route.

[0106] Specifically, all areas between the starting point and the end point of the recycled battery transportation process where the loading module can travel are divided into the entire operating area. The entire operating area is divided into several sub-areas with a square with a side length of 1m, and the part beyond the edge of the entire operating area is bounded by the edge of the entire operating area.

[0107] Specifically, the central control module determines that the transportation performance of the loading module does not meet the standards based on the situation that the preset operating rate is reduced for three consecutive preset times and the operating stability still does not meet the standards, and determines to load all the recycled batteries with the third-level battery risk in the next loading cycle.

[0108] Specifically, under the condition of a flat road surface, the loading module slowed down three times in a row, indicating that its transportation performance did not meet the requirements for transporting recycled batteries with secondary battery risks and primary battery risks. All recycled batteries with primary battery risks were loaded, thereby improving transportation efficiency while ensuring the transportation safety of the recycled batteries.

[0109] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
