Busbar Manufacturers

Whether the busbars are for the cell to cell interconnects or the main busbars connecting the cells to the contactors, fuses and out to the connectors they all need careful design and manufacture.

Advanced Chemical Etching

ACE busbars

For the very specialist busbars.

Chemical etching can remove metal locally, providing the required thickness at the point of contact with the cell while maintaining maximum cross-sectional area across the remainder of the bus bar to address the current conduction requirements.

ACE can perform a number of added value services that are required when manufacturing certain EV components including metal forming, plating and heat-treating.
