Daily maintenance of lithium-ion power lithium battery pack

Daily maintenance of lithium-ion power lithium battery pack (1) Check the appearance of the battery pack. The battery pack cover and electrode column should be clean, and there should be no dust, metal shavings and other dirt. If there is, it should be cleaned with compressed air; the battery pack casing should not have cracks, swelling, deformation, loose poles and other abnormal conditions; The battery cover and the tray should be kept sealed, and the joint between the battery and the car body should be tightly fitted. (2) Check the battery connection status. The connection of the battery pole connector should be firm and reliable, and there should be no corrosion; each connection point of the single battery and the contact of the battery pack conductive belt, voltage, temperature collection terminal and other nodes should be reliable, and there should be no looseness, falling off, or rust. Or deformation; the charging plug should be in good contact with the socket. (3) Leakage detection of battery pack. In order to reduce the working current of the electrical equipment of electric vehicles, the working voltage of the lithium-ion battery pack generally adopts a voltage specification above 300V DC, so the automobile lithium-ion power lithium battery pack has high insulation requirements. The insulation performance of an electric vehicle is measured by the insulation resistance of the battery pack’s DC positive and negative bus bars to the ground. According to the national standard for electric vehicles GB/T18384.1-2001, the insulation resistance of the battery pack to the ground is divided by the electric vehicle The nominal voltage U of the DC system is greater than 100ON, which meets the safety requirements.
