Question 1

Do EV chargers need to be certified in California?

Accepted Answer

Yes. EV charging equipment that bills consumers by kilowatt-hour is classified as a commercial measuring device under California BPC Division 5. It must be tested and certified by a CDFA-registered RSA before being placed in commercial service. No grace period once billing begins.

Question 2

What is a Registered Service Agency (RSA)?

Accepted Answer

A Registered Service Agency (RSA) is a business registered with the California CDFA Division of Measurement Standards. RSAs are authorized to test, certify, and place in service commercial measuring devices including EV chargers. ChargeScale EV holds RSA registration #5129.

Question 3

What types of chargers require certification?

Accepted Answer

Any EV charger that measures electricity and bills customers requires certification. This includes Level 2 AC chargers and DC fast chargers at commercial sites, public facilities, workplaces, and multi-unit dwellings. Free chargers that don't bill do not require certification.

Question 4

What is AB 2037 and does it apply to my EV chargers?

Accepted Answer

AB 2037 effective January 1, 2026 extended county sealer jurisdiction to EV chargers operated by public agencies. If your municipality, utility district, or public facility bills users for EV charging, AB 2037 means your equipment is now subject to Weights and Measures verification.

Question 5

What are the accuracy tolerances for EV chargers in California?

Accepted Answer

Per 4 CCR Section 4002.11 Table T.2: AC Level 2 chargers require acceptance tolerance of plus or minus 1.0% and maintenance tolerance of plus or minus 2.0%. DC fast chargers (pre-2033 devices) require acceptance tolerance of plus or minus 2.5% and maintenance tolerance of plus or minus 5.0%.

Question 6

What regulations govern EV charger certification?

Accepted Answer

California BPC Division 5 establishes the legal framework. Technical standards are defined in 4 CCR Section 4002.11, EPO No. 52 (Examination Procedure Outline), and NIST HB 44. County sealers enforce compliance through inspections and testing.

Question 7

How long does EV charger certification take?

Accepted Answer

Most on-site certifications take 2-4 hours depending on the number and type of chargers. After testing, ChargeScale EV prepares documentation and submits certification records to the county sealer. Total turnaround is typically 1-2 weeks.

Question 8

What is the cost of certification?

Accepted Answer

Pricing varies based on charger type, quantity, location, and any repairs needed. We provide transparent quotes after assessing your site. Contact us for a custom estimate.

Question 9

Can you certify chargers remotely?

Accepted Answer

Most certifications require on-site testing to verify accuracy and functionality. However, we can provide remote consultations for documentation review, compliance planning, and pre-certification assessments.

Question 10

What documentation do I need for certification?

Accepted Answer

Have available: charger model numbers, serial numbers, installation dates, any previous certification records, and documentation of any repairs or software updates. We'll guide you through what's needed during the assessment.

Question 11

How often do EV chargers need to be recertified?

Accepted Answer

California requires recertification following any metrologically significant software update, hardware repair, or at the interval established by the county sealer. County sealers inspect commercial EVSE on a two-year cycle. Addressing recertification proactively is more efficient than responding to enforcement.

Question 12

What triggers recertification requirements?

Accepted Answer

Recertification is required after: software updates affecting measurement accuracy, hardware repairs or component replacement, physical relocation of the charger, or when the county sealer mandates re-inspection during their two-year inspection cycle.

Question 13

How do I know when my chargers need recertification?

Accepted Answer

ChargeScale EV provides certification records with dates. County sealers typically notify operators when inspection is due. We recommend setting calendar reminders and monitoring for any software updates from your charger manufacturer.

Question 14

What happens if my EV chargers are never certified?

Accepted Answer

Uncertified EV chargers expose operators to consumer complaints, CDFA enforcement action, and potential liability. Per BPC Section 12510, violating Division 5 is a misdemeanor. For public agencies, uncertified equipment can jeopardize user fee authority and LCFS credit eligibility.

Question 15

Can I be fined for operating uncertified chargers?

Accepted Answer

Yes. County sealers can issue citations and fines for operating uncertified or out-of-tolerance equipment. Violations can result in equipment seizure and legal action. Certification protects you from these penalties.

Question 16

How do county sealers identify uncertified chargers?

Accepted Answer

County sealers conduct routine inspections, respond to consumer complaints, and review public charging networks. They test chargers for accuracy and verify certification records. Proactive certification prevents enforcement issues.
