H55 Successfully Completes All Regulator-Required Propulsion Battery Module Certification Tests

H55 has actually finished the sector’s initial regulator-required and authority observed propulsion battery component qualification examination series, dealing with a vital gating variable the business claims has actually constricted the commercialisation and funding of electrical airplane programs.

Finished in December 2025, the EASA-supervised project offers certification-level proof that business lithium battery cells can be incorporated right into aeronautics propulsion battery systems with the ability of securely having worst-case failing situations, particularly fire breeding.

André Borschberg, Exec Chairman and Founder of H55, claimed: “H55 was produced with a solitary goal: to make electrical aeronautics certifiable, not simply feasible. From the beginning, that implied developing systems around aeronautics security requirements and stopping failing while optimizing efficiency.

” This landmark verifies that option. Electric aeronautics can be crafted to satisfy the exact same qualification technique and security assumptions as standard airplane. At H55, disciplined, concentrated passion is what equates qualification right into genuine market fostering and scalable business influence.”

Regarding the Examination Project

To implement this project, H55 created greater than 100 examination posts attracted from its accepted and examined item setup.

The six-month initiative covered ecological, security, practical, and efficiency problems under worst-case failing settings, consisting of authority-witnessed thermal runaway examinations without breeding. Jointly, these outcomes verify preparedness for qualification and commercial release, consisting of:

• Conclusion of the qualification advocate propulsion battery components
• Verification that H55 stays the only organisation holding both EASA Style Organisation Authorization (DOA) and Manufacturing Organisation Authorization (POA) for electrical propulsion systems
• Manufacturing of series-manufacturing-conforming propulsion battery components
• Conclusion of the initial EASA-validated cell characterisation advocate qualified propulsion battery systems
• The security shown throughout screening finished in December 2025 is currently being recorded right into last examination records, which H55 is sending to EASA for official approval in Q1 2026

From Recognition to Scalable Qualification

The examination project was performed in a qualified manufacturing center utilizing serial-conforming equipment (not models) produced with verified procedures. It verifies H55’s capacity to designer and manufacture propulsion battery systems constructed to qualification requirements on regulatory-approved production lines and supply chains.

H55’s one-of-a-kind, copyrighted Power Storage space System style installs surveillance, redundancy, and danger reduction at the cell degree as fundamental concepts, making sure control of severe failing problems regular with aeronautics security needs.

This technique develops a repeatable qualification path for H55’s battery modern technology, as opposed to progressing a solitary airplane program.

By specifying a certification-grade battery component recommendation structure, H55 materially lowers fostering danger for airplane makers, drivers, insurance firms, and financiers by making it possible for actuarial danger evaluation based upon authority-validated failing information as opposed to programme-specific presumptions.

With qualification proof able to worsen throughout a large range of airplane systems, resources, design sources, and commercial ability can broaden without symmetrical boosts in programme-level unpredictability.

The system structures developed with H55’s initial adapting propulsion battery system currently sustain sped up growth and regulative progression for both completely electrical and hybrid-electric airplane.

The information, facilities, and certification-standard proof created with this project underpin numerous continuous consumer programs, consisting of the BRM B23 Energic, CAE’s change towards all-electric pilot training systems, and the hybrid-electric Dashboard 8 presentation program with Pratt & Whitney Canada.

With greater than twenty years of electrical aeronautics experience, 6 electrical airplane created, constructed, and flown, and over 2,000 completely electrical trip hours gathered with no battery-related cases, H55 brings the functional deepness needed to carry out certification-grade programs– not simply follow them.

Cleaning the Qualification Traffic jam to Allow Scalable Commercialisation

Electric aeronautics ranges on qualification. By finishing this regulator-approved propulsion battery component examination project, H55 has actually materially lowered the main restriction that identifies which electrical aeronautics innovations can commercialise.

Official presentation of control under worst-case failing situations materially lowers regulative and insurance coverage direct exposure, opening repeatable, certifiable release throughout airplane programs while making sure aircraft-level security.

A solitary, certifiable Power Storage space System design can currently be released throughout numerous systems, enabling qualification proof to substance as profits possible expands without symmetrical boosts in growth price, sustaining repeatable release throughout fleets and airplane lifecycles as opposed to one-off program distributions.

With propulsion battery-module qualification danger currently attended to, electrical aeronautics steps from speculative growth to a certifiable commercial group– improving just how programs are assessed, funded, and guaranteed.

Rob Solomon, Principal Exec Police officer of H55, included: “This success notes a architectural inflection factor for electrical aeronautics. By finishing the initial EASA-agreed battery component examination project, H55 has actually attended to the most crucial technological traffic jam on the qualification course, materially minimizing danger for airplane makers, drivers, insurance firms, and financiers.

” By supplying surveillance, energetic and easy defenses of every specific cell, H55 changes the propulsion battery from a ‘ black box’ of unrealized danger right into an actuarially clear property, developing cell-level surveillance as the non-negotiable limit for both regulative kind qualification and fleet insurability. What’s most amazing, is the engine-like company design this allows for H55.

” In parallel, with a joint multi-authority Qualification Administration Group, EASA and the UNITED STATE Federal Air Travel Management (FAA) have actually devoted to common acknowledgment of concurred ways of conformity for continuous programs. Examination outcomes will certainly be moved to the FAA, supplying a basis for sustaining and speeding up H55’s united state qualification tasks and market visibility.”
