It’s official: the Series 5, Series 6, Series 7, and Series 8 commercial EV charging stations are now CTEP-certified. This essential certification was added this year for 2021 for public EV charging stations in California. But what is CTEP and why does it matter for charging your electric vehicle?
What is CTEP?
The California Type Evaluation Program (CTEP) is administered by the California Department of Food and Agriculture’s (CDFA) Division of Measurement Standards (DMS). Before equipment can be sold for commercial use in California, it must be approved by the DMS. CTEP is how the DMS evaluates a product before issuing a Certificate of Approval.
Until now, EV charging stations did not require CTEP nor DMS certification. But in 2019, California’s Office of Administrative Law approved amendments to existing specifications for electric vehicle fueling systems. Because electricity is a motor fuel, it is now regulated by DMS, at least when it comes to charging vehicles. Starting in 2021, EV charging stations installed for public use must have CTEP certification and can no longer bill users per minute. To help drivers better predict their charging costs, if using a payment policy, California EV station owners must bill per kilowatt-hour (kWh). (They can, of course, offer free electricity to drivers if they choose.)
CTEP Requirements for EV Charging
The California Type Evaluation Program ensures that when it comes to EV charging, what you see is what you’ll get. Imagine going to a fuel station and not knowing how much you’ll pay, or even how much fuel will be delivered to your vehicle! CTEP-certified EV charging stations such as the Series 5, Series 6, and Series 8 have been evaluated to ensure that you receive the kilowatts that you expect.
Requirements for Public EV Supply Equipment (EVSE)
Level 2 charging stations installed before January 1, 2021 must comply with the following requirements by January 1, 2031. Level 2 charging stations installed on or after January 1, 2021 must comply upon installation. Compliance will be required for DC fast charging stations, but there is a grace period. DCFC must comply beginning in 2023.
- EVSE must have safety certifications from a nationally recognized testing laboratory prior to application for CTEP evaluation
- EVSE must be correct to the 0.0005 MJ or 0.0001 kWh.
- EVSE must display the price in cents per megajoule (MJ) or kilowatt-hour (kWh), or clearly state that charging is free. For example, the station might bill at $0.12 kWh or $0.119 kWh.
- EVSE must display the maximum power and type of power, such as 7 kW AC power.
- EVSE must display how much power has been delivered
- EVSE must be accurate and correct in the temperature range of -40F to 185F.
- EVSE must conspicuously and legibly state the voltage rating, maximum current deliverable, type of current, minimum measured quantity, and temperatures if narrower than the required range
How Does CTEP Certification Help SemaConnect Station Owners and Drivers?
When you charge at a SemaConnect charging station, you expect your charging session details and bills to be correct. CTEP certification proves that you will receive the energy that you expect. While the time it takes to charge your EV can vary based on usage, temperature, electrical supply, or battery technology, the energy flow displayed on the SemaConnect LCD screen is correct. And if you’re using a charging station that charges you an “energy transferred” fee, you can know that your bill is correct.
