NORMA Group has developed thermal management line systems for a battery manufacturer, Fastener + Fixing Magazine reports. The line systems will be installed in the electric passenger cars of a major international automobile manufacturer.

Production will begin in 2020, with some 400,000 electric vehicles to be equipped with NORMA Group systems by 2025, according to Fastener + Fixing.

“As an industrial equipment supplier with a strong focus on the automotive sector, our ambition is to play an active role in shaping the growth in the area of electromobility,” stated NORMA Group CEO Dr. Michael Schneider. “This order once again illustrates that leading automobile manufacturers are relying on NORMA Group’s development expertise for demanding electromobility projects.”

Used in the battery packs of the electric vehicles, the line systems ensure the correct operating temperature of the battery cells. “In this way, the systems make a significant contribution to the optimal performance of the battery and help increase the range of the vehicles,” writes Fastener + Fixing deputy editor Claire Aldridge. “The service life of the battery is also substantially influenced by the thermal management of the cells.”

Integrated temperature sensors in the line systems also regulate the coolant temperature.

Battery internal thermal management line systems must meet high design and technical requirements, since battery packs must accommodate as many cells as possible to achieve the optimal performance. Compactness and efficient line routing allow NORMA Group’s thermal management systems to be installed inside the battery in a space saving format.

“To ensure that the batteries function reliably and safely in the long-term, it is also essential the line systems and all connections are absolutely leak-free,” Aldridge writes. “In development partnership with the customer, the thermal management line systems were optimised to minimum tolerances.”

Laser welding technology is used to meet the automaker’s high requirements for connection precision, cleanliness and tightness. This high precision manufacturing method allows for thermoplastic joining elements to be reliably and safely joined to thermoplastic smooth or corrugated pipes, according to Fastener + Fixing.

The line systems are manufactured at NORMA Group’s plant in Pilica, Poland, where an on-site test laboratory supports rapid product development and continuous quality control.

Germany-based NORMA Group manufactures joining products in three categories (clamp, connect and fluid) and offers more than 35,000 products to 10,000 customers in 100 countries. Web: NormaGroup.com
