IONCHI, the high‑power charging joint venture formed by BMW and Mercedes‑Benz, has added AITO as an equal shareholder, expanding its platform for premium electric vehicle (EV) charging services in China.

SERES, through its premium brand AITO, announched that it will acquire a one‑third stake in IONCHI, joining the two German automakers on equal terms. With the transaction, each partner will hold a 33.3% share in the charging venture, which was established in 2024 to develop a nationwide high‑power public charging network.

IONCHI focuses on ultra‑fast charging infrastructure located in prime urban areas, combining high power availability with station operations, customer service and the use of renewable energy. The move is intended to support further geographic expansion, increase network density and broaden access to premium charging services as China’s electric mobility market continues to grow.

BMW and Mercedes‑Benz said AITO’s participation strengthens the platform’s growth prospects and brings additional scale to the partnership. The expanded shareholder group plans to work jointly on network development and service innovation, with a shared focus on charging quality and reliability.

As the network expands, IONCHI aims to play a broader role in China’s e-mobility ecosystem by integrating advanced technologies and supporting sustainable transport initiatives. The transaction remains subject to regulatory approval.
