Project Overview

The EVI US project addresses the challenge of privacy-preserving user authentication in electric vehicle (EV) charging. It introduces a decentralized identity framework allowing drivers to authenticate charging sessions without exposing personal information.

Certificates are issued and stored in EVs or wallets, enabling automatic authorization at charging stations. The system was tested with ISO 15118-compatible infrastructure in New York, ensuring user privacy and compliance with ESSIF standards.

Methods and approaches

Decentralized Identity (DID)

Self-sovereign identity certificates stored in vehicle or wallet.

Plug-and-Charge Mechanism

Enables automatic session initiation without personal data.

OCPI-Compatible Middleware

Ensures integration with existing EV apps and chargers.

User-Centric UX/UI Design

Simplified onboarding and fallback methods.

Behavioral Insights

Surveys and interviews to validate preferences.

Key Achievements

Live pilot at Mega HQ in New York with a Zerova AC charger.

Full integration with EV Loader platform and Walt.id wallets.

Certificate-based Plug-and-Charge preferred by over 90% of users.

13 chargers configured; over 20 users onboarded.

Open-source middleware and modular architecture published.
