Seres joins BMW and Mercedes-Benz in a major step to expand high-power EV charging infrastructure in China, signaling deeper collaboration between global luxury automakers and a rising Chinese EV player.
Equal Partnership in IONCHI Network
Chinese automaker Seres has officially entered the fast-charging joint venture originally formed by BMW Brilliance Automotive and Mercedes-Benz Group China. With this move, Seres joins BMW and Mercedes-Benz as an equal shareholder, with each partner holding a 33.3% stake in the venture, now branded as IONCHI.
Boosting Charging Infrastructure Across China
The partnership aims to accelerate the rollout of EV charging infrastructure in the world’s largest automotive market. The IONCHI network plans to establish at least 1,000 high-power charging stations with around 7,000 charging piles by the end of 2026. This expansion is critical as demand for reliable and fast EV charging continues to surge across China.
Aito Brand to Play Key Role
Seres confirmed that its premium EV brand, Aito, will actively contribute to the development of the IONCHI network. As Seres joins BMW and Mercedes-Benz, Aito vehicles will directly benefit from enhanced charging accessibility and integration within the network.
Premium Features for Customers
Although the charging network will remain open to all EV users, customers of BMW, Mercedes-Benz, and Aito will enjoy exclusive features such as plug-and-charge functionality and online reservation systems. These offerings are designed to deliver a seamless and premium user experience.
Strategic Collaboration in a Competitive Market
As Seres joins BMW and Mercedes-Benz, the partnership highlights a rare but strategic collaboration between Chinese and German automakers. With competition intensifying in China’s EV and charging sectors, such alliances are becoming essential to scale infrastructure and strengthen market presence.
This move reinforces how Seres joins BMW and Mercedes-Benz to compete more effectively in China’s fast-growing luxury EV ecosystem.
