Seres Group Joins Ionchi Charging JV Expanding Premium EV Infrastructure in China

Seres Group has officially entered the high-power EV charging space through a strategic investment in Ionchi, a premium charging joint venture originally established by BMW and Mercedes-Benz in China. This move creates a rare three-way collaboration between a Chinese automaker and two German luxury car manufacturers, signaling deeper integration in the country’s fast-evolving electric mobility ecosystem. The partnership reflects a growing emphasis on shared infrastructure development to accelerate EV adoption and enhance customer experience.

Equal Shareholding Structure Strengthens Collaboration

Ionchi was founded in 2024 as a joint venture between BMW Brilliance and Mercedes-Benz, with both companies initially holding equal stakes. With the inclusion of Seres Group, the ownership structure has now evolved into a three-way equal partnership, with each automaker holding a 33.3% share. This balanced equity distribution is expected to promote collaborative decision-making and aligned strategic direction, especially as the joint venture expands its network footprint and technological capabilities across key regions.

Expansion of Premium Charging Infrastructure in China

The Ionchi network focuses on delivering a high-quality public charging ecosystem tailored to premium EV users. The infrastructure is strategically deployed in high-traffic urban commercial areas, ensuring accessibility and convenience. The network emphasizes ultra-fast charging performance combined with reliable operations and superior customer service. This approach aligns with the broader goal of enhancing the premium electric mobility experience, particularly in competitive metropolitan markets where charging convenience plays a critical role in EV adoption.

Aito Brand Gains Strategic Charging Advantage

The inclusion of Seres Group directly benefits its premium EV brand Aito, which will gain access to Ionchi’s expanding charging infrastructure. Aito customers are expected to experience enhanced convenience through features such as online reservation systems and prioritized charging access. These benefits aim to differentiate premium EV ownership by integrating seamless charging solutions with vehicle ecosystems. At the same time, the network remains open to all eligible EV users, maintaining its role as a public infrastructure platform.

Future Growth and Regulatory Approval Process

The partnership is positioned to unlock new opportunities in network expansion, geographic coverage, and service innovation. BMW and Mercedes-Benz have expressed support for the inclusion of Seres, highlighting the strategic value of combining expertise across markets and technologies. However, the transaction is still subject to regulatory approval in China, which is a standard requirement for such joint venture arrangements. Once approved, the collaboration is expected to accelerate infrastructure rollout ahead of upcoming product launches, including new Aito models scheduled for release.
