Ultrasonic welding technology to extend battery life

Cadillac ELR battery pack manufacturing process, using high-tech ultrasonic welding process to ensure that this luxury extended-range electric coupe with excellent quality. Each battery pack ELR nearly 200 joints, each solder joint quality of the process has stringent requirements, only advanced welding technology to do the job. Ultrasonic welding has also shorten the manufacturing cycle, reduce costs and enhance production line elastic assets and other advantages.

Cadillac ELR by the Cadillac Converj concept car changed its name from, Dimensions follows Converj design style, it is a hybrid car. According to GM news, paragraph 2014 battery pack manufacturer Cadillac ELR will use ultrasonic welding technology aerospace, pharmaceutical and other fields of use. Have a positive impact this technology will have battery life.

Currently, the assembly work ELR lithium battery pack is close to Detroit within a town named Bu Langzi universal battery assembly plant is. Each ELR lithium batteries chargeable 16.5 kwh, can use 240V power supply within 4.5 hours of the battery pack is fully charged. Mileage 56 km in pure electric mode. ELR lithium Leader 1.6 meters and weighs 198 kilograms, is located ELR central axis, has a T-shaped profile, the weight can be very evenly distributed to the front and rear axles, providing 400 Nm of peak torque.

Compared with conventional heating pads are not the same, the use of ultrasonic welding in welding two metal pieces so without the need to weld the metal sheet is heated to a temperature, but by the friction surfaces of the metal sheet of high frequency to achieve the same effect.
Ultrasonic welding basic constituent elements are: a can exert strong pressure on the press, it can be used to load a set of materials to be processed and can withstand high strength friction force to undertake stations and drills, a variable frequency signal generator.

Battery electrode manufacturing aluminum copper alloy ELR will use ultrasonic welding technology, which makes the production of the battery pack in a more efficient, more flexible, less costly, while able to produce a more stable performance and longer life battery pack (Cadillac Official guaranteed by the technology produced by the battery life of up to an average of 8 years or 160,000 kilometers).
