Large EV battery packs can contain thousands of cells that have to be connected to form modules and packs, then connected via busbars to other driveline components such as inverters and DC-DC converters to make robust and reliable connections quickly and efficiently in confined spaces while keeping costs down.
That has made the design and construction of busbars and interconnect systems an important subject of r&d as voltages get higher and the thermal conductivity of their components becomes increasingly important to cooling. Engineers therefore face a set of challenges in designing and manufacturing these systems, particularly in mass-production environments. More…
