Precautions for the use of automotive lithium-ion power lithium battery packs and introduction to daily maintenance

Precautions for the use of automobile lithium-ion power lithium battery pack (1) When using and cleaning the car, care should be taken to prevent the lithium-ion power lithium battery pack from impact and water. (2) When the meter shows that the power is low, the lithium-ion power lithium battery should be charged in time to prevent the power lithium battery from affecting the normal use of the battery and even shorten the service life of the power lithium battery. (3) When a battery overheating alarm occurs while the car is running, stop to cool the battery and continue driving after the overheating warning light goes out; if there are frequent battery overheating alarms or the battery failure warning light is always on, the fault should be promptly performed by professionals Excluded, it is strictly forbidden for non-professionals to disassemble and assemble the battery pack by themselves to avoid personal injury. (4) When the battery catches fire, use dry sand or nitrogen fire extinguisher to extinguish the fire. (5) If the vehicle is stopped for a long time, in order to prevent the battery pack from losing power and affecting its service life, the negative electrode of the battery pack should be removed, and the power lithium battery should be charged regularly once a month. 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 the voltage specification above 300V DC, so the lithium-ion power lithium battery pack of the automobile has a high insulation requirement. 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.
