Read the first 7 EV Charging Standards flashcards as text

  1. Which protocol governs communication between a charging station and its central management system (CSMS)?

    Answer: OCPP

    OCPP (Open Charge Point Protocol) links chargers to their back-end management system.

  2. Which protocol enables roaming between different charging network operators and e-mobility service providers?

    Answer: OCPI

    OCPI (Open Charge Point Interface) exchanges data between networks for roaming and billing.

  3. Under federal NEVI minimum standards (23 CFR 680), what is the minimum continuous power each DC port must be capable of delivering simultaneously at a 4-port station?

    Answer: 150 kW

    NEVI requires each of four DC ports to deliver at least 150 kW at the same time.

  4. NEVI rules require each charging port to maintain what minimum average annual uptime?

    Answer: 97%

    23 CFR 680 requires greater than 97% uptime per port.

  5. Which UL standard covers the safety of AC electric vehicle supply equipment (Level 1 and Level 2)?

    Answer: UL 2594

    UL 2594 covers AC EVSE, while UL 2202 covers DC charging system equipment.

  6. Per NEC Article 625, EVSE is treated as a continuous load. How must the branch circuit be sized for a 40 A EVSE?

    Answer: At least 50 A (125% of load)

    NEC 625.41 requires overcurrent protection rated at not less than 125% of the maximum load, so 40 × 1.25 = 50 A.

  7. Which UL standard applies to bidirectional EV charging equipment used for vehicle-to-grid or vehicle-to-home applications?

    Answer: UL 9741

    UL 9741 covers bidirectional EV charging system equipment.
