Busbar connector alternative to electroplating

Penn Engineering has developed a new technique to reduce the cost of busbar connections in electric vehicles, writes Nick Flaherty. “The challenge is how to connect busbars,” says John O’Brien, global technologist at Penn Engineering. “One of the things we have seen is a move from cabling to busbars, driven by cost. Busbars are much cheaper for the same current than cables and more suited for automated assembly, which also gives lower cost.”
