How Precision Etching Overcomes Material Limitations Within EV Components
EV Battery Systems
EV battery systems comprise of modular cells which can be utilised in varying multiples depending on the output required. These cells have an electro-mechanical interconnect between each other known commonly as a bus bar.
The bus bar needs to maintain the inherent thickness to be able to conduct the necessary current output. However, upon contact with the cells, the bus bar needs to be permanently fixed to the cell contacts.
Heat Fixing Limitations
This is when thickness can become a problem. Usual methods of fixing, like laser welding, require heat and thus the heat required to penetrate the full thickness is so much that further damage occurs within the cell.
Etching As A Solution
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.
Not only does chemical etching offer the benefits stated previously, but as material is removed it also offers the added benefit of weight reduction which again is a key critical element for EV designers to increase the range of future vehicles.
ACE can perform a number of added value services that are required when manufacturing certain EV components including metal forming , plating and heat-treating.
