Internal Box Maintenance Of Battery Box

(1) There should be no foreign objects or rubbing caused by vibration inside the inner box. Both the power line and the acquisition line are double insulated and clearly marked, and there must be no mutual collision, rubbing, or vibration. The low-voltage and high-voltage lines of the fan power supply are arranged separately and clearly labeled. The connection between the management module and the wiring board (terminal block) should be smooth, of appropriate length, neatly tied, and free from any rubbing during vibration. The cable tray cover on the protective cover should not be higher than the highest point of the protective cover, and the crimping should be reliable and not loose, to ensure smooth operation when the inner box is pulled out or pushed in. The installation position of the fan is correct, flat and not skewed, and the fastening is reliable and not loose. There is no collision or rubbing between the fan movement and each connection. The handle positions are located on both sides of the panel air outlet.
(2) Add three labels on the assembled battery box panel: battery material label, high voltage warning label, and box number label; Another manual unlocking instruction needs to be pasted. All labeling and instructions must be completed in accordance with national standards.
(3) The opening and closing operation of the battery box is completed by two people working together simultaneously.
(4) When manually opening the battery box, first gently pull out the pull button of the manual mechanism from the rubber holes in the lower left and right corners of the panel for easy grip. Then, both left and right people use their other hand to push the panel inward, while holding the pull button and pulling it to the limit position. At this point, the operator can pull the handle position of the panel to pull out the battery box.
(5) After the battery box is pulled out, it can only be placed on a manual tray or storage rack. It should not be placed on hard objects and should not come into direct contact with conductive materials.
(6) When installing the battery box, use an automatic replacement system or a manual replacement system. Adopting an automatic system does not require direct human contact with the battery box. When using a manual system, gently push the battery box onto the roller track of the outer box. When approaching the bottom of the outer box, both operators apply force simultaneously, quickly pushing the person, and hear a "click" sound, indicating that the battery box has been locked in place. At this point, it is necessary to manually pull the handle position to check if the battery box is securely locked.
(7) During the operation of the battery box, there may gradually be more dust covering the surface of the battery housing. Therefore, whenever the vehicle runs for more than 1000 km, the interior of the battery box needs to be cleaned of dust. At the same time, it is also necessary to clean the dust on each filter screen.
(8) The electrical components and sensors inside the battery box are regularly maintained or calibrated according to the manufacturer's requirements.
(9) During operation, a simple visual inspection of the high-voltage pole socket is required for each replacement to check for surface wear and erosion.
