Comau unveils laser laboratories to make EV batteries and motors

Comau has introduced new laser laboratories to support companies as they develop, implement and optimize the laser processes involved in constructing and assembling e-motors and batteries. With two labs in Grugliasco (Turin)—one specialized in batteries and the other dedicated to e-motors—plus additional labs in Shanghai and Detroit, Comau now offers a range of laser processes for various industrial sectors.

Comau’s laser labs are equipped with Comau NJ-220 robots, which are powered by the LHYTE (Laser Hybrid Technology) system. LHYTE is suitable for many different applications, thanks to a patented solution which makes it possible to automatically alternate between fiber and diode lasers to ensure optimal high-precision joining, which is vital in the assembly of a battery or e-motor. LHYTE can also work with different melting temperatures of materials such as copper and aluminum.

Comau’s laser laboratories can be adapted to suit the process required and the type of product to be manufactured. Projects are supported by engineers who develop or identify a welding solution for each customer, with services ranging from feasibility studies through process optimization.

“We can create any type of battery pack for any power level and are able to assemble the entire electrical battery, from the welding of individual cells which make up a module, to the stacking of the various modules contained in a battery pack, right through to the laser welding of the entire case,” explains Comau CTO Giovanni Di Stefano. “We are also developing a similar solution for hairpin motor laser welding at our newest lab.”
