Electroflight launches new modular energy storage unit

Aviation energy storage specialist Electroflight has today announced the launch of a new COTS Energy Storage Unit, designed to advance prototype development in electric aviation projects.

SEED is a Scalable, Expandable, Energy Device that can be rapidly deployed without the need for the expensive and time-intensive process of creating a bespoke battery system. Designed for use in early-stage product development, it responds to a growing need from aerospace innovators for pre-certification development electric and hybrid aircraft for test operations, which require a battery system with the highest levels of quality and safety.

It can be used in a variety of applications in the aerospace segment including hybrid, full electric and eVTOL projects, ultimately allowing companies to drive innovation and testing before investing in a full-scale bespoke battery system. The compactness of the system also means that SEED can be used in challenging packaging envelopes – particularly in smaller aircraft where space and weight is at a premium.

Douglas Campbell, technical director of Electroflight, said: “The launch of SEED is extremely exciting for us as it represents the next step in our journey as a company and a key milestone on the journey to making electrified aviation a reality. The technology in the SEED system has been built on the foundations of the groundbreaking innovation we developed for the world record-breaking ACCEL project and further strengthened from battery supply partnerships with eVTOL and CS23 aircraft customers. We are now productising this technology so that it can inspire others to further innovation in this space.

“We are already seeing high levels of demand for the system,” Campbell added. “One leading operator in the electric aviation space has already placed a major order, requesting A samples by Q1 2023 and B samples and first flight in Q2 2023. Another two are very close to finalising orders. We think this could be a game-changer for the sector and will be further adding to the SEED module family in the coming months. We are looking forward to partnering with more companies thanks to this innovative new technology.”

Developed in Gloucester at Electroflight’s state-of-the-art centre, the new battery will carry 4.3kWh and offering 196 Wh/kg. It has an operating temperature of -20 to +60 °C at discharge and 0 to +60 °C at charge. In addition, the battery is able to contain and manage thermal runway, has a fast-charging capability, a self-contained Battery Management System, and a full individual cell temperature coverage capability.
