COMUNICATO STAMPA – CONTENUTO PROMOZIONALE<\/p>\n

SION,\u00a0Switzerland, April 29, 2026 \/PRNewswire\/ — H55 today announced the successful completion of its System Safety Function Verification Testing, marking a key milestone in the validation of its integrated Energy Storage System (ESS) and its progress toward certification.\u00a0<\/p>\n

In the final stages toward certification, H55 successfully validated its Energy Storage System (ESS) in a fully integrated configuration, bringing together all critical subsystems into a complete and operational architecture. The test setup included Battery Modules (BMs), Battery Management Units (BMUs),\u00a0Energy\u00a0Flow\u00a0Counter\u00a0(EFC), Protection\u00a0and\u00a0Power Distribution\u00a0Unit\u00a0(PPDU) and\u00a0the\u00a0Charge Control Unit (CCU).\u00a0<\/p>\n

The campaign focused on validating system-level performance, communication integrity, and\u2014critically\u2014safety functionality under real operating conditions.\u00a0The results confirmed robust and reliable\u00a0coordination\u00a0across all\u00a0subsystems,\u00a0ensuring stable\u00a0and\u00a0predictable\u00a0system\u00a0behavior\u00a0across a range of scenarios.\u00a0<\/p>\n

A key outcome of the campaign was the successful verification of critical safety functions at system level, including the automatic and controlled disconnection of power under predefined fault or off-nominal conditions\u2014an essential capability for safe operation in aviation environments.\u00a0\u00a0<\/p>\n

Beyond hardware validation, this milestone represents a significant step in de-risking H55’s software verification and certification roadmap, with all system safety functions performing as expected within an integrated architecture.\u00a0<\/p>\n

“This milestone represents a major step in de-risking both our technology and our certification roadmap,”\u00a0said Anthony D’Ambrisi, Head of H55’s Design Organization. “By validating system-level safety functions in a fully integrated architecture, we are demonstrating readiness for certification\u2014not\u00a0just\u00a0at\u00a0component level,\u00a0but\u00a0as\u00a0a\u00a0complete system. This is an important step toward industrialization and large-scale deployment.”\u00a0<\/p>\n

Unlike many emerging players developing systems in isolation, H55’s ESS has been engineered in alignment with certification requirements from the outset, in close coordination with aviation authorities including EASA.\u00a0The\u00a0system is\u00a0developed\u00a0to\u00a0aerospace-grade standards, well beyond experimental or “permit-to-fly” approaches.\u00a0<\/p>\n

With more than a decade of experience in electric aviation, H55’s safety philosophy goes beyond managing failure\u2014focusing instead on detecting, controlling, and mitigating risks before they escalate. This approach enables a higher level of system reliability and is fundamental to achieving certification in demanding aviation environments.\u00a0<\/p>\n

The successful completion of this campaign marks a critical step in bringing H55’s technology from validation to deployment. With active programs underway and growing demand for certified electric propulsion solutions, H55 is positioned to support aircraft manufacturers and operators in the transition toward electrified flight.\u00a0<\/p>\n

As\u00a0the\u00a0aviation industry\u00a0accelerates\u00a0toward decarbonization,\u00a0H55’s\u00a0integrated\u00a0and\u00a0certifiable\u00a0energy storage systems are enabling a new generation of electric aircraft\u2014designed not just to fly, but to scale.\u00a0<\/p>\n

About H55\u00a0<\/p>\n

H55 is a Swiss-based company specializing in certified electric propulsion and certification-grade energy storage systems for aviation. The company enables electric aviation to scale by transforming commercial lithium cells into aviation safe Energy Storage Systems that regulators approve, insurers underwrite, and OEMs can deploy repeatedly as a certified propulsion platform across aircraft programs. This is achieved through independent cell characterization, rigorous incoming screening, redundant safety architectures, and regulator-aligned testing designed around worst-case failure scenarios.\u00a0<\/p>\n

Founded as the technological legacy of the Solar Impulse program, H55 builds on more than two decades of hands-on electric aviation experience.\u00a0The company has designed, built, and flown multiple\u00a0electric\u00a0aircraft and\u00a0has\u00a0accumulated\u00a0more\u00a0than\u00a02,000 hours\u00a0of\u00a0fully electric\u00a0flight\u00a0with\u00a0zero battery-related incidents\u2014providing the operational depth required to execute certification-grade programs, not merely comply with them.\u00a0<\/p>\n

H55\u00a0benefits\u00a0from\u00a0a\u00a0strong and\u00a0experienced\u00a0leadership\u00a0team\u00a0that\u00a0combines deep\u00a0expertise\u00a0in\u00a0scaling technology companies with hands-on operational execution.\u00a0Together, these capabilities support a reliable transition from certified design to repeatable series manufacturing.\u00a0H55’s platform-based approach, in which certification evidence compounds across programs, reduces adoption risk while facilitating the capital-efficient deployment of electric and hybrid-electric aircraft.\u00a0<\/p>\n
