VT Netzwelt

Ambare-e is a growing EV charging infrastructure provider in Brazil, operating across private, semi-public, and public charging environments. Their hardware was already in place, but drivers had no reliable way to monitor charging sessions, locate available chargers, or manage charging remotely. Inconsistent firmware protocols also created connectivity challenges between the mobile app and physical chargers. VT Netzwelt worked closely with Ambare-e’s firmware team to design and build a scalable software system for real-time charger communication. The solution enabled Bluetooth Low Energy connectivity for nearby charger pairing, Wi-Fi-based remote access, QR code access for public chargers, and flexible logic for private, semi-public, and public charging environments. The backend was built on AWS services including IoT Core, Lambda, DynamoDB, and Cognito to support real-time monitoring, user management, and future scalability.
