Vehicle electrification systems are comprised of batteries, cables, inverters, motors, and other high-power electrical devices. Electric systems depend on the reliable interconnection of these components. Requirements go beyond joint strength; joints must be vibration resistant and have low electrical resistance, high current carrying capacity, and high thermal conductivity. EWI has worked on interconnects for different...

While ultrasonic and laser welding are both effective methods for battery foil welding, neither can be monitored in process. So when a battery batch is defective, the problem is not identified until after material, time, and money as been spent. EWI recently tested a resistance spot welding technique that uses a capacitive discharge power supply...
