Case Study: Proterra achieves OCPP 1.6-compliant EV charging infrastructure with Promwad

Proterra improves EV charging reliability with Promwad in 24h

The customer, Proterra, an American EV technology company, faced challenges with the firmware for its electric vehicle charging stations, including poor code maintainability and bugs. They engaged the vendor Promwad to refactor the code and implement the Open Charge Point Protocol (OCPP 1.6) to improve system management and enable compatibility with various charging station management systems.

Promwad's solution involved a two-phase approach: first refactoring the existing firmware and moving critical code to a Linux kernel driver for improved stability, and then integrating the Open OCPP library. This implementation by Promwad resulted in a more reliable and maintainable system for Proterra, which reduced equipment and maintenance costs and provided compatibility with a wider range of management systems, giving them a competitive advantage.
