[0067] Specifically, the operating data includes a voltage fluctuation factor, a current fluctuation factor, a temperature fluctuation factor, and a power level; if one of the voltage fluctuation factor, the current fluctuation factor, and the temperature fluctuation factor is greater than its corresponding threshold value, it indicates that a battery pack in the battery pack 3 is damaged, and the battery pack to be replaced is located and displayed; if the power level is less than the power level threshold value stored in the database, the battery pack 3 is low in power and is replaced; if the voltage fluctuation factor, the current fluctuation factor, the temperature fluctuation factor, and the power level are not less than their corresponding threshold values, a comprehensive analysis is performed to obtain a battery status value; the battery status value is compared with the battery status threshold value stored in the database; if the battery status value is less than the battery status threshold value, the battery pack 3 is damaged and needs to be replaced, and the battery pack to be replaced is located and displayed; if the battery status value is not less than the battery status threshold value, the battery pack 3 is not damaged and does not need to be replaced.

[0068] The calculation formula of battery status value is:

[0069]

[0070] Where Dz is the battery state value, Dy is the voltage fluctuation factor, Db is the current fluctuation factor, Wd is the temperature fluctuation factor, Dl is the power, Dl0 is the reference power stored in the database, α1 is the weight factor of Dy stored in the database, α2 is the weight factor of Db stored in the database, α3 is the weight factor of Wd stored in the database, and α4 is the weight factor of |Dl-Dl0| stored in the database.

[0071] In this implementation, the battery pack's health can be accurately determined by monitoring and analyzing operational data such as voltage, current, temperature, and power. This avoids misjudging the battery's status due to a single abnormal data indicator, making battery pack replacement decisions more scientific and rational, reducing unnecessary replacement operations and ensuring the vehicle's normal operation. Reasonable monitoring and precise replacement decisions can prevent damage to the battery due to excessive use or premature replacement before the battery reaches replacement standards, thereby extending the battery pack's overall service life and reducing battery usage costs. Promptly detecting and addressing battery pack anomalies, especially for explosion-proof mining vehicles, can effectively prevent safety incidents caused by battery failure, such as overheating and short circuits, which can lead to explosions or fires, thereby ensuring the safety of mining workers and the safety of equipment and property.

[0072] The above-mentioned settings of α1, α2, α3, and α4 are obtained from the database. Based on historical data, the historically calculated Dy, Db, Wd, |Dl-Dl0|, and Dz are established. A mapping set of Dy, Db, Wd, |Dl-Dl0|, and their corresponding weight factors is established to obtain the current α1, α2, α3, and α4. The following β1, β2, and β3 are also obtained through the mapping set of historical data and weight factors established in the database, that is, the corresponding weight factors are obtained based on the current data.

[0073] Specifically, the battery pack to be replaced is located and displayed, which specifically includes the following steps: obtaining the battery abnormality data of each battery pack in the battery pack 3, the battery abnormality data including the voltage deviation ratio, the current deviation ratio, and the temperature deviation ratio, and comprehensively analyzing to obtain the comprehensive abnormality index of each battery; comparing the comprehensive abnormality index of each battery with the battery abnormality comprehensive index threshold stored in the database, selecting the battery pack corresponding to the battery abnormality comprehensive index greater than the battery abnormality comprehensive index threshold, marking it as the damaged battery pack to be replaced, and displaying it.

[0074] The calculation formula for the comprehensive battery abnormality index is:

[0075]

[0076] Where Y i Yp is the comprehensive index of battery abnormality of the i-th battery pack, iis the voltage deviation ratio of the i-th battery pack, Lp i is the current deviation ratio of the i-th battery pack, Wp i is the temperature deviation ratio of the i-th battery pack, Yp is the reference voltage deviation ratio stored in the database, Lp is the reference current deviation ratio stored in the database, Wp is the reference temperature deviation ratio stored in the database, β1 is the |Yp stored in the database i -Yp| weight factor, β2 is the |Lp stored in the database i -Lp| is the weight factor, and β3 is the |Wp stored in the database i -Wp| weighting factor.

[0077] This implementation analyzes and comprehensively evaluates the multi-dimensional deviation ratios of each battery pack, accurately identifying damaged battery packs. This avoids blind inspection and replacement of the entire battery pack, saving time and labor costs. Maintenance personnel can directly identify damaged battery packs to be replaced based on the displayed information, eliminating the need for time-consuming investigation and testing. This significantly reduces vehicle downtime for repairs, enabling mining vehicles to resume operation more quickly and improving overall operational efficiency in the mine. Thresholds determined based on extensive historical and experimental data provide a more scientific and accurate assessment of battery pack damage, reducing false positives.

[0078] In a specific embodiment, the voltage fluctuation factor, current fluctuation factor, temperature fluctuation factor and power are not less than their corresponding thresholds. In the operating data, Dy is 0.1, Db is 0.12, Wd is 0.15, Dl is 20%, Dl0 is 15%, α1 is 0.25, α2 is 0.25, α3 is 0.25, and α4 is 0.25. Dz is calculated to be 0.75, and the battery status threshold is 0.8. If the battery status value is less than the battery status threshold, the battery pack 3 is damaged and needs to be replaced.

[0079] Yp in the battery abnormality data of the i-th battery group i 0.18, Lp i is 0.3, Wp i is 0.4, Yp is 0.2, Lp is 0.32, Wp is 0.37, β1 is 0.3, β2 is 0.4, β3 is 0.3, calculate Y i is 1.16, the battery abnormality comprehensive index threshold is 1.34, Y i If the value is not greater than the battery abnormality comprehensive index threshold, the battery pack does not need to be replaced. The remaining battery packs are calculated similarly. The battery pack corresponding to the battery abnormality comprehensive index greater than the battery abnormality comprehensive index threshold is selected, marked as the damaged battery pack to be replaced, and displayed. The replacement operator can replace the corresponding battery pack according to the displayed data.

When the first box door 4 rotates to open a certain angle, the slider 28 can no longer move in the slide groove 27, and the first box door 4 continues to rotate, and the placement plate 14 is pulled outward by the curved rod 29 and the slider 28 to move the battery pack 3 outward. During this process, the fourth gear 37 drives the tooth plate 39 to move, but does not engage with the fifth gear. The gear 40 is connected until the first box door 4 rotates ninety degrees. At this time, the third gear 35 is separated from the second gear 31 above, the first box door 4 stops rotating, and the drive motor 49 continues to operate. At this time, the toothed plate 39 is meshed with the fifth gear 40, and the two sixth gears 41 rotate. The third transmission member 42 drives the screw rod 43 to rotate, and the pushers 44 on both sides push the battery pack 3 and the placement plate 14 outward. The first slide rail 15 slides in the first connecting plate 16, and the battery pack 3 drives the card block 20 and the connecting plate 14. The block 24 moves in the connecting groove 25, and the inclined surface of the connecting block 24 gradually comes into contact with the inclined surface of the connecting groove 25. When the connecting block 24 gradually moves to the bottom of the fixing frame 26, the connecting spring 23 is stretched, and the clamping block 20 moves downward, separates from the battery pack 3, and contacts the limit of the battery pack 3. At this time, the electromagnetic block is energized and magnetically connected to the metal block on the insertion rod 45, releasing the lock on the battery pack 3, and the battery pack 3 can be pulled out from the outside for replacement. The reverse operation can be performed to lock and install the replaced battery pack 3.
