Encrypted Certificates for EV Charging Authentication
Summary
USPTO published patent application US20260100852A1 on April 9, 2026 (filed September 19, 2025) covering encrypted certificate systems for electric vehicle charging authentication. The invention describes generating encryption/decryption key pairs and encrypted certificates containing test results for vehicle charging components. A charging component detects a connection, identifies a charging partner request, and transmits encrypted certificates with decryption keys to authenticate the charging session.
What changed
USPTO published a patent application describing encrypted certificate authentication systems for electric vehicle charging. The system generates encryption keys, decryption keys, and encrypted certificates containing test results for vehicle charging components. When a charging component detects an electrical connection and determines it corresponds to a charging partner request, it transmits the encrypted certificate and decryption key for authentication.
EV charging equipment manufacturers and technology companies developing charging infrastructure should monitor this patent application for potential licensing implications or to assess whether their authentication methods may overlap with the claimed innovations in encrypted certificate-based EV charging authentication.
What to do next
- Monitor for patent grant status
- Review authentication methods for EV charging compliance

Abstract
The various implementations described herein include methods and devices for equipment authentication for electric vehicle charging. In one aspect, a method includes receiving a plurality of test results for a vehicle charging component and generating an encryption key, a corresponding decryption key, and an encrypted certificate for the vehicle charging component. The method also includes providing the encrypted certificate and the decryption key to the vehicle charging component. In another aspect, a method performed at a vehicle charging component includes detecting an electrical connection at a charging port of the vehicle charging component, determining that the electrical connection corresponds to a request to begin a charging process with a charging partner, and transmitting an encrypted certificate and a decryption key to the charging partner. The encrypted certificate includes encrypted test results for the vehicle charging component, and the decryption key can be used to decrypt the encrypted certificate.
