Weights and Measures Regulation FAQ

The California Division of Measurement Standards (CalDMS) is the agency charged with setting standards for measuring devices in the State of California. The agency sets technical standards that are then enforced by counties. This agency's goal is to ensure that 1) a measuring device is accurate, ensuring consumers are getting what they pay for, and 2) that there is equity among business competitors. You can read more about their work in the EV charging space here.

It is your responsibility as a station owner to comply with all state and county regulations. Here is a summary of actions you may need to take depending on when your charger was installed and if/how you collect fees from drivers for charging services:

• All stations that charge a fee to drivers, regardless of installation date, should:
  • Be registered with the local county. These regulations, with a few exceptions (see “Which EVSE will not be subject to the regulation?” here), impact stations that charge either a per kilowatt-hour or time-based fee. Visit your county's weights and measures department page for registration information. AND
  • Have clearly and conspicuously displayed information detailing the names, address, and phone number of the local responsible party for the EVSE. See example image to the right:
• In addition:
  • Level 2 (or AC) stations that charge a fee and were installed on or after 1/1/21 must be “Placed in Service” by a Registered Service Agent.
  • DC Fast Chargers that charge a fee and were installed on or after 1/1/23 must be “Placed in Service” by a Registered Service Agent.

Registered Service Agents (“RSAs”) are certified by the State to test your station's measurement capabilities. They will field test and verify your station in accordance with State procedures, apply a sticker indicating your station's compliance, and notify the local county that it has been tested. If your station was installed on or after the dates listed above, please find an RSA who can help you complete the “Placed in Service” requirement in your area.

If you have questions about how to comply with these regulations, we suggest you contact your local county.

You can find a list of agents and agencies provided by the state here. You can also contact RSAReferrals@chargepoint.com for a list of ChargePoint’s recommended RSAs.

Each county will set its own cost for device registration. You can learn more about these costs here or on your local County’s website.

There is also an additional cost associated with the “Placed in Service” requirement. Contact a service provider (see: “How do I find a Registered Service Agent (RSA)?” above) to request a quote.

If your CPF50 station model number contains “GW-LTE” and was installed on or after 1/1/21, follow guidance in the section titled “If I own or plan to own an EV charging station, what should I do to comply with California weights and measures regulations?”

If your station model number starts with CPF25 or your CPF50 model number does not contain “GW-LTE”, we recommend you take one of the following actions to comply with the regulations:

1. Change the pricing policy to include only a flat session or parking fee; OR
2. Offer free charging.
3. Contact your ChargePoint account representative about this issue.

To check your charging station model number, log into your ChargePoint network account and view “Stations.” To update your pricing policy, access “Stations” > “Pricing and Reservations." For additional assistance, access “Support Center”.
