Hitachi Energy and Eve team up to build eVTOL charging network

Hitachi Energy and Eve have formalised a partnership to create the charging backbone needed for electric vertical take‑off and landing (eVTOL) aircraft, a move that could accelerate the rollout of urban air mobility services across major cities. The collaboration, reported by Aviation International News and Valor International, merges Hitachi’s power‑grid expertise with Eve’s aircraft and operations platform, aiming to deliver scalable, fast‑charging stations for the emerging eVTOL fleet.

Core developments

The two companies announced that they will co‑develop, test and commercialise a suite of charging solutions specifically engineered for eVTOL aircraft. Hitachi Energy will contribute its high‑voltage power conversion technology, grid‑integration tools and experience in large‑scale renewable‑energy projects. Eve, a subsidiary of Embraer’s urban‑air mobility arm, will supply the aircraft‑side charging interface, site‑selection expertise and operational data that inform charger design.

According to the press release cited by Aviation International News, the partnership will focus on three deliverables: a modular charging unit that can be installed at vertiports, a software platform that manages energy demand and distribution, and a set of standards that align with emerging eVTOL battery specifications. The joint effort is positioned to address the “chicken‑and‑egg” problem that has slowed eVTOL deployment, namely the lack of reliable, high‑power charging points at take‑off and landing sites.

Valor International notes that the collaboration also includes a pilot programme slated for later this year, where a prototype charger will be installed at a designated vertiport in a Japanese city. The pilot will evaluate charger performance under real‑world operating conditions, including rapid turnaround times between flights and integration with local grid constraints.

Why it matters

eVTOL aircraft promise to cut urban travel times, reduce surface congestion and lower emissions, but their commercial viability hinges on a robust charging ecosystem. Unlike conventional aircraft that refuel at centralized airports, eVTOLs must recharge at numerous vertiports scattered throughout densely populated areas. Each charging event can demand several hundred kilowatts of power for a short period, creating spikes that traditional distribution networks are not designed to absorb.

Hitachi Energy’s portfolio includes high‑voltage converters, battery‑energy‑storage systems and grid‑balancing software that have been deployed in renewable‑energy installations worldwide. By applying that know‑how to the eVTOL sector, the partnership could deliver chargers that not only provide the necessary power but also smooth demand peaks, preventing strain on municipal grids.

Eve’s role is equally critical. As a developer of eVTOL aircraft and operator of vertiport concepts, Eve possesses detailed knowledge of battery architectures, charging curves and operational schedules. Aligning charger specifications with aircraft requirements ensures that the infrastructure will be compatible with multiple eVTOL models, fostering a multi‑vendor ecosystem rather than a proprietary lock‑in.

The collaboration arrives at a time when several eVTOL manufacturers, including Joby Aviation, Archer and Volocopter, are racing to obtain certification and launch limited commercial services. Governments in the United States, Europe and Asia are also drafting regulatory frameworks for urban air mobility, many of which reference the need for “sustainable and resilient” charging solutions. A joint effort from two industry leaders could set a de‑facto standard that regulators and city planners adopt.

Differing viewpoints and reactions

Hitachi’s corporate communication highlighted the partnership as a natural extension of its commitment to decarbonising transportation. A spokesperson for Hitachi Energy said the company sees eVTOL charging as “an opportunity to apply our expertise in high‑power conversion and grid integration to a fast‑growing mobility segment.” The tone was optimistic, emphasizing the potential for the joint technology to “enable reliable, low‑emission urban air transport at scale.”

Eve, on the other hand, framed the collaboration as a step toward operational readiness. In its statement, the company noted that the ability to charge aircraft quickly and safely at vertiports is “the missing piece that will allow operators to deliver on‑demand services without compromising turnaround time.” Eve’s leadership stressed that the partnership would also feed data back into aircraft design, creating a feedback loop that could improve battery performance over time.

Industry analysts, while not quoted directly in the source articles, have expressed cautious optimism. Some point out that the success of the pilot will depend on local regulatory approvals, grid capacity and the willingness of municipalities to allocate space for vertiport infrastructure. Others argue that the partnership’s focus on modular, scalable hardware could lower entry barriers for smaller cities, democratising access to urban air mobility.

What’s next

The immediate next step is the installation of the prototype charging unit at the selected vertiport, with testing expected to begin in the fourth quarter of 2026. Data collected during the pilot will inform refinements to the charger’s power electronics, cooling system and software controls. Both companies have indicated that, contingent on successful testing, a rollout of additional stations could commence in early 2027, initially targeting high‑traffic corridors in Japan’s major metropolitan areas.

Beyond the pilot, Hitachi Energy and Eve plan to engage with city governments, aviation authorities and other eVTOL manufacturers to broaden the standards they are developing. The aim is to publish a set of technical specifications and interoperability guidelines by mid‑2027, providing a reference point for future vertiport projects worldwide.

Finally, the partnership could influence investment patterns in the urban air mobility sector. By demonstrating a viable charging solution, the collaboration may unlock financing for vertiport construction, encourage airlines to consider eVTOL fleets and prompt utilities to allocate resources for grid upgrades. As the technology matures, the combined expertise of Hitachi Energy and Eve may become a cornerstone of the eVTOL ecosystem, shaping how cities of the future move people and goods through the sky.
