Afcon-EV Case Study

Meet the Customer

A leading public EV charging operator with a nationwide network of fast and ultra-fast sites serving fleets, municipalities, residential complexes, and commercial centers.

Keynotes

Domain: EV charging operation (CPO)
Go-Live: Days
Time to Answer: Seconds
Data Stack: CPO platform + CRM/ERP + partner/roaming feeds

Challenges

Raw→Report overhead — too much time/energy from raw data to usable reports.
Cross-system visibility — charging sessions, crm and partners.
Need answers now — site/connector status, queue risk, SLA breaches in seconds.
Network analysis — pinpoint issues and faults.
Capacity & investment — where to add connectors/power upgrades first.
Minimal IT lift — integrate new domains fast; avoid heavy BI projects.
Data-driven decisions — shift to fact-based decisions despite previously limited data access.

Tango Solution

Tango delivered its app, integrated with the CPO’s operational data, and introduced a natural-language interface that returns insights in seconds—narrative, tables, or charts. Every answer is explainable and source-backed to site, connector, session, and partner entities. Data is not shared with LLM providers, with role-based access separating different users. Teams can spin up dashboards and schedule alerts/reports in a click.
