Problems solved by technology
Tape winding is inconvenient, easy to age, and the winding method varies from person to person, and the insulation effect is not good, which affects the production efficiency of the battery system and the consistency of product quality
The insulating cap needs to be worn on the connector. During the process of fastening the bolts and nuts, it is easy to be pressed into the conductive parts, resulting in poor contact of the conductive parts and increased resistance. It is easy to cause fire due to heat during the operation of the battery box. Combustion, a threat to the overall safety of electric vehicles
