We all know that the battery pack is the "heart" of new energy vehicles, and the module is like a "tissue", composed of smaller "cells" and a larger heart organ.

The battery module is a single physical module assembled by connecting multiple cells in series and parallel, providing higher voltage and capacity. The assembly of the module needs to consider the production yield, efficiency and internal resistance of the connection point. Currently, laser welding is the first choice of many battery manufacturers. The design and manufacturing process of the module have an important impact on the performance and safety of the battery pack.
