Battery connector series

The battery connector isKWTThe new products developed are mainly in line with the series of new energy vehicles: cars, buses, high-speed trains, cloud trains, trucks and other power lithium batteries came into being. The battery connector is also called the power lithium battery cover connector, which is the positive and negative connector. As an important part of the power lithium battery, the battery connector is a channel through which the battery converts chemical energy into electrical energy to connect with the outside world.

The sealing of the battery connector in the industry is mostly concentrated in the gap between the battery connector and the battery cover, and the structural performance of the battery connector itself is often ignored, which causes the electrolyte to be caused by the internal pressure of the battery. The connector will corrode outward, and even leak the electrolyte, which will damage the battery connection or affect the battery life. Due to the structural defects of the existing battery connector itself, it also has problems such as weak structural strength, weak pressure resistance, poor heat dissipation, and poor insulation.

KWTThe battery connector developed, the positive pole head is made of aluminum1060Make stigma, pass glass, ceramics and coat aluminum3003The combination is packaged into a whole through co-sealing sintering process engineering; its negative pole head consists of negative pole and base oxygen-free copperT2Composed by welding, and jacket aluminum3003It is packaged into a combined whole through glass and ceramic co-sealing sintering process engineering. The positive pole head, the negative pole head and the battery panel are combined to form the positive pole and the negative pole on the power lithium battery sealing panel, which are used as the channel interface ends for transmitting electric energy.KWTThe battery connector integrated board developed is to use the power lithium battery pack to seal the panel aluminum3003, As a jacket for one or several pairs of pole heads of the power lithium battery pack. The positive pole and negative pole components are packaged with glass and ceramic co-sealing sintering process engineering into a combined whole, and the positive pole and negative pole of the power lithium battery seal panel are combined into the power transmission channel interface end.
