[0003] In the prior art, large-section conventional wires are commonly used to transmit current between the battery packs of new energy electric vehicles and the power source. Due to the high current of up to 1000 A when charging the battery pack, the temperature rise of the conventional wires is large, making it difficult to meet the requirements and even causing fires. In addition, the conventional wires use copper cores, and the cost of large-section copper cores is very high.

However, the aluminum busbar wires in the prior art only include a single aluminum busbar. When multiple different conductive components need to be electrically connected separately, multiple aluminum busbar wires need to be provided, which can make the electrical connection inconvenient and result in a large volume and high cost of the electrical connection product.
