In the realm of EV charging, adhering to rules and standards is non-negotiable. The U.S. National Type Evaluation Program (NTEP) is the cornerstone of this commitment, granting certifications to companies responsible for manufacturing and operating EV chargers. This certification process, overseen by NTEP, meticulously checks whether these chargers align with the mandates set forth in the NIST Handbook 44 (HB 44) which sets rules for how fuel pumps and electric vehicle chargers must work, ensuring fairness and transparency in EV charging transactions. While some states have already embraced these rules, others are gearing up to implement them by January 1, 2025. The validation process is typically conducted by specialized NTEP-approved labs; California has its own independent program for this, the California Type Evaluation Program (CTEP).
The role of the Open Charge Alliance (OCA)
The Open Charge Alliance (OCA) is at the forefront of championing adherence to EV charging standards. Currently working on a white paper, the OCA aims to facilitate seamless implementation of these requirements across various states and raise awareness about the significance of NTEP and the California Type Evaluation Program (CTEP) within the key players of the market.
In the realm of price display and tariff implementation, the OCA is actively developing mechanisms to ensure accurate price and tariff visibility via the Charging Management System (CPMS). While OCPP 1.6 falls short in facilitating the communication of pricing details, OCPP 2.0.1 steps up by offering standard messages for transmitting pricing information to charging stations. However, achieving this seamless communication necessitates meticulous customization on both the Central System and charge point ends. Perfect alignment of these customizations is paramount for successful operation.
Network operators need to comply with the federal requirements by integrating with NTEP/CTEP-compliant CPMS.
As federal requirements evolve and tighten, network operators must seamlessly integrate with NTEP/CTEP-compliant CPMS to ensure conformity. The requirements for electric vehicle supply equipment (EVSE) are extensive:
- Transparent Pricing: EVSE units must display the price per charge and indicate charge start and stop times. If multi-tiered pricing is employed, all tier prices must be visible before charging begins.
- Accurate Measurement: EVSE should display and record electrical output and price in kilowatt-hours (kWh) and their decimal subdivisions.
- Continuous Pricing Display: EVSE units should maintain ongoing price displays and cost calculations throughout a charging session, even in the absence of internet connectivity.
- Transaction Integrity: The indicating element’s reset mechanism must not activate during a charging transaction.
- Clear Power Output: EVSE units must be labeled clearly with their maximum power output.
- Accuracy Verification: EVSE units need to be field-tested for accuracy, matching the energy delivered with the cost charged.
- Detailed Receipts: Drivers should receive comprehensive receipts itemizing the cost of their charging session and offering additional information.

The CTEP certification process
Embarking on the path to California Type Evaluation Program (CTEP) certification involves a systematic approach to ensure your EV charging business aligns with the highest standards. Here’s a concise breakdown of the steps to obtain a Certificate of Approval (COA) through CTEP:
- Application Submission: Begin by completing the application for a COA, which can be submitted via email or traditional mail to the Department of Measurement Standards (DMS). Accompany your application with a non-refundable application fee of $500.
- Engagement with Evaluator: Once your application is received, an evaluator will engage with you to discuss specifications and requirements. They will document their evaluation process through observations and photographs, which will be incorporated into your COA documentation.
- Evaluator Fee: Before the evaluation process can commence, you will be required to settle an evaluator fee which typically encompasses service costs, equipment expenses, travel, and per diem allowances.
- Evaluation Approval and COA Issuance: Following a thorough evaluation, if the DMS approves the results, you will receive your COA via mail.
CTEP’s far-reaching benefits for EV charging
In essence, CTEP certification not only validates your commitment to high standards but also contributes to the broader objective of shaping the EV charging landscape into a seamlessly integrated and user-friendly ecosystem. As we journey toward a future dominated by electric vehicles, adhering to the standards outlined by the CTEP program becomes instrumental in achieving a unified and enhanced charging experience for all.
