Read the first 7 Communication and Networking Systems flashcards as text

  1. What is the primary role of a VPN in an EVSE network architecture?

    Answer: Provide secure encrypted communication between EVSE and back-end systems

    A VPN creates an encrypted tunnel between the EVSE and back-end systems, protecting sensitive data from interception on public or cellular networks.

  2. Which network protocol automatically assigns IP addresses to EVSE units on a network?

    Answer: DHCP

    DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to networked devices, including EVSE, eliminating the need for manual static configuration.

  3. In the context of EV charging networks, what does 'roaming' mean?

    Answer: Using a charging station from one network while authenticated through another

    Roaming allows an EV driver to charge at a station operated by a different network than the one they subscribed to, similar to cellular phone roaming between carriers.

  4. The OCPI (Open Charge Point Interface) protocol is primarily designed for:

    Answer: Enabling roaming between different EV charging networks

    OCPI is an open protocol that enables different EV charging networks to share data and allow driver roaming, so users can charge across multiple network operators.

  5. What cybersecurity practice is most essential for protecting EVSE data transmitted over public networks?

    Answer: TLS/SSL encryption for all communications

    TLS/SSL encryption secures data in transit between EVSE and central systems, preventing eavesdropping or man-in-the-middle attacks on public and cellular networks.

  6. What does 'Plug & Charge' functionality primarily require to work correctly?

    Answer: A secure communication protocol between the vehicle and EVSE

    Plug & Charge uses ISO 15118 to establish a secure, encrypted communication channel between the EV and EVSE, enabling automatic authentication and billing without driver action.

  7. What is the primary purpose of a back-office system in EVSE network management?

    Answer: To handle billing, session management, and remote station monitoring

    The back-office (or back-end) system manages billing, user accounts, charging session records, remote diagnostics, and station monitoring for an EV charging network.
