Delta AI customer service strengthens charging-station service: powering smarter EV charging

Delta has long invested in EV-charging infrastructure in the energy-tech field, deploying large numbers of charging stations at home and abroad. As users grew rapidly, real-time on-site consult volume surged too — but most stations are unattended, so when users hit a problem they often can't find help. Delta partnered with OSENSE to deploy Qubby AI customer service, handing on-site consults, anomaly resolution, and policy explanations all to AI in real time.

Pain point: no one to ask on site, and big language gaps

• Charging issues are diverse and time-sensitive, with no one to ask on site
• Anomalies like failed starts or connection failures need fast resolution
• Many domestic and overseas users with varied language needs and local policy / pricing differences
• Lack of personalized charging advice wastes time or affects battery life
• High live-support load can't meet frequent, real-time queries

Solution: Qubby AI tailored for EV charging

Qubby AI integrated Delta's existing charging-station manuals, troubleshooting flows, and local charging policies and pricing into a unified knowledge core, paired with semantic understanding, NLP, and multilingual interaction — so users can ask in their own language right at the station and get instant answers.

• Real-time charging diagnostics: AI identifies user questions and provides charging steps, troubleshooting, and how-to guidance
• Multilingual and localized support: supports Chinese, English, and more, with local charging policies, pricing, and usage rules
• Personalized charging advice: recommends the best charging plan by vehicle type and habits, balancing time and battery life
• Service-load offloading: AI handles large volumes of repetitive consults, easing live-support pressure
• Stronger brand tech image: smart service reinforces Delta's leadership in energy tech

Results: upgraded charging experience, sharply lower support load

After deploying Qubby AI, Delta's charging-station service went from "find someone to help" to "instant smart advisor." Users can resolve any charging-related issue on site through AI; multilingual support and localized info give domestic and overseas users a consistent experience. For Delta, Qubby isn't just a support tool — it's key infrastructure that strengthens brand tech image and service differentiation.
