It is very often presented that the lithium battery pack cannot be charged. When the pure electric vehicle lithium battery pack cannot be charged, it can be roughly divided into the following reasons: raindrops maintenance may be invalid, the charging head is connected or charged. Faults, lithium battery packs and high -power electrical appliances short -circuit. After presenting this problem, the first to check the charging head, the positive and negative error, and whether the line has not been broken. After you figure out the corresponding reasons, repair it. Another problem is that lithium batteries cannot be discharged. For this problem, lithium battery packs can be used to charge, finding heat insulation boards or line connections.

　　Lithium batteries will also show a battery dissatisfaction. This situation is because the single string of electricity consumption in the lithium battery pack may be different. This condition can use the balanced charging head to charge the lithium battery pack, so that the operating voltage of each string is the same. If the condition is more severe, you can directly replace the lithium battery pack.

　　Now the rapid development of technology, the use of electronic products is increasing, and the use of natural batteries has continued to increase. According to the continuous development of lithium batteries, the utilization rate of lithium batteries is getting higher and higher. In real life, because the voltage of the device is different, the voltage of the lithium battery is different, and the voltage must be matched with the device.

　　The lithium battery pack can be distinguished according to the voltage number, with 72 V as the boundary, below 72 volt is a low -voltage lithium battery pack, and above 72 volt is a high -voltage lithium battery pack. It can also distinguish the lithium battery pack according to the field. The lithium battery packs used in different areas will also be different, such as AGV, medical, military, energy storage, and cleaning lithium battery packs. In these categories, the use of lithium battery packs is relatively wide.

　　The reason for being used is mainly its advantages. Firstly, it has a long life and a lot of cycles, with a life span of 5 to 6 years. The detailed time should be based on the equipment it uses; second, its weight and volume are relatively light; third, it has no memory effect and is attributed to environmental protection. Battery. In short, the lithium battery pack can distinguish the lithium battery pack according to different voltage numbers and different use scope.
