Supernal and Electric Power Systems (EP Systems) have partnered to develop safe, lighter-weight and certifiable eVTOL vehicle batteries, having formalised an agreement at last week’s Farnborough International Airshow 2022.

Resulting in the first vehicle partnership for Supernal, the aim is to introduce commercial eVTOL vehicle flights and support increasing enhancements to vehicle performance as the advanced air mobility (AAM) market matures.

Part of Hyundai Motor Group, Supernal plans to work within an ‘open ecosystem’ model that will address the niche technology needs of AAM.

Hyundai Motor Group president and Supernal CEO Jaiwon Shin said: “Advanced Air Mobility requires an expansive value chain and many aspects, from battery power to digital infrastructure and passenger experience, require improvements and cross-chain integration to enable progress.

“We are excited to work with Electric Power Systems and develop game-changing technologies that will revolutionise air travel and increase human possibility.”

Supernal will continue growing its network of battery talent and partners to drive power, energy, charging time and cycle life improvements that will lead to longer, more affordable eVTOL vehicle flights.

Electric Power Systems president and CEO Nate Millecam added: “We are pleased to partner with Supernal as it seeks to democratise flight and create a new, sustainable transport category.

“Supernal’s long-term perspective and comprehensive approach to developing the AAM space has enabled it to be viewed as an industry thought leader and savvy partner of choice.”

EP Systems’ experience has given the company a broad perspective on the electric evolution taking place throughout aviation, where all-electric aircraft need high-density energy storage.

Current EP Systems customers include NASA, the Federal Aviation Administration, Boeing, Safran, Bell Textron, Diamond Aircraft, VoltAero, Aura Aero and Embraer.

Last week, Supernal revealed the interior cabin concept of its eVTOL aircraft for the first time at the Farnborough International Airshow, giving attendees the opportunity to see how Hyundai Motor Group will integrate automotive capabilities to develop the AAM market.

In June 2021, Electric Power Systems released its EPiC battery module during an eVTOL Writers Group interview organised by the Vertical Flight Society.
