Transition to electric mobility is accelerating and is forecast to further accelerate. However, long charging times remain a key barrier to the wider adoption of electric vehicles (EVs).

Shortening these charging times requires higher battery voltages up to 1,000V or above. To enable this ultra-fast charging at the right safety and reliability levels, manufacturers will need to use insulation plastics with better resistance to high voltages.

DSM Engineering Materials has taken the next step on its journey to making electric vehicles safer, lighter and more sustainable by expanding its comparative tracking index (CTI) test laboratory to meet the next-generation, high voltage requirements of its customers.

By installing advanced CTI test capabilities, it is now enabling a new standard to support manufacturers in increasing the voltage of EV batteries safely and shortening charging times even further to help accelerate the shift to electric mobility.

Portfolio and approach that have been established by DSM Engineering Materials:

• Safety:
  Leveraging its expertise in critical applications, DSM Engineering Materials is ensuring that key future mobility systems – like the e-powertrain, connectivity, tanks and structural parts – are made with the most reliable, material solutions that meet or exceed application standards while at the same time reducing the carbon footprint of the component.

• Lightweighting:
  DSM Engineering Materials has extensive expertise making structural parts, including actuation systems and seating materials, lighter with ForTii PA4T PPA and Akulon PA6 and PA66 PAs, offering best-in-class strength and thermal performance for metal replacement.

• Sustainability:
  As a sustainability leader, DSM Engineering Materials has communicated its bold ambition to reduce its total greenhouse gas emissions and the carbon footprint of its products by 50% by 2030, from a 2016 baseline, and developing and rolling out bio- and/or recycled-based alternatives for its entire portfolio by 2030. Specific grades are already available for all major product lines.

Now, DSM has expanded its CTI test laboratory with equipment to validate tracking resistance to voltages up to 1,500V AC and 1,000V DC. High-voltage component manufacturers have shown high interest in collaborating with DSM on this testing for voltages between 600 and 1,500V.

Franz Janson, Principal Product Development Engineer, PEE Global Automotive Resin Material Platform at TE Connectivity, mentioned, “We are very happy to see that DSM is investing in strong materials as well as the right test laboratory. We look forward to cooperating more closely to understand the impact of high-voltage exposure on material properties and to implement suitable materials for our next-generation high-voltage systems.”

Jud Gibson, Global Vice President of Sales & Marketing at DSM Engineering Materials, said, “To introduce such an advanced electrical test laboratory enabling CTI characterization is a key milestone for DSM and an industry first. We’re proud to be using this technology to make electric cars safer, lighter, and more sustainable – not only for today’s customers, but also for generations to come.”
