Brand Refresh: From a Two-Partner Luxury Joint Venture to a Three-Way Partnership

IONCHI was founded in March 2024 as a 50:50 joint venture between Mercedes-Benz and BMW. On April 17, 2026, IONCHI announced that AITO would join. The transaction closed on September 29, with each of the three shareholders holding a 33.3% stake in IONCHI, establishing a three-way partnership of BMW, AITO and Mercedes-Benz.

With its shareholder structure settled, IONCHI has also elevated its brand positioning - from a joint-venture brand of two luxury automakers to an open, premium supercharging brand built by three partners. The new brand identity is the visual expression of that positioning. A new logo is the outward sign of the upgrade; the real substance lies in the experience. Taking the refresh as its new starting point, IONCHI will keep turning its brand philosophy - “Supercharge at ease, glide with grace” - into an experience users can feel.

Technology and Service Upgrades

IONCHI’s new-generation liquid-cooled supercharger delivers up to 800 kW of output and a maximum current of 800 A across a wide 200–1000 V voltage platform. Compatible with 99.9% of mainstream EV models on the market, it adds 400 km of range in just 10 minutes of charging.

On the user side, IONCHI keeps making charging simpler and more comfortable, with a lightweight charging connector, plug-and-charge with seamless payment, low-noise operation and a fast-response customer service team available 24/7. Together, these technologies and services make up IONCHI’s seamless supercharging system, taking charging from merely usable to truly effortless.

User Ecosystem Upgrade

Alongside the brand refresh, IONCHI App 3.0 is now live, with a fully redesigned interface that is cleaner and simpler to use. The app’s role has changed too: no longer just a charging tool, it is now the gateway to IONCHI’s premium user ecosystem. Building on its existing points program, IONCHI has launched a tiered membership system with differentiated benefits spanning charging discounts and exclusive events. Users can check their membership tier and benefits in the IONCHI mini program. IONCHI has also launched a loyalty rewards plan, offering exclusive thank-you benefits to users who supported its charging service early on. From today until November 30, all users can buy a membership worth RMB 6.9 for just RMB 0.1 (one per person). Existing users can also redeem 50 points for an RMB 3 service fee coupon, now valid throughout November instead of only on weekends. All benefits can be viewed and claimed in the IONCHI mini program.

An Open Network for Drivers of Every Brand

As of October 2026, IONCHI’s network covers 40 cities in 22 provinces, with 619 supercharging stations and 3,404 charging points located in CBDs, core commercial districts and along major urban roads. By the end of 2027, IONCHI plans to have at least 1,000 supercharging stations with around 7,000 supercharging points.

IONCHI’s supercharging network is open to all EV drivers. On top of that, BMW, AITO and Mercedes-Benz drivers enjoy exclusive brand benefits such as charging reservations, special discounts and priority power allocation.
