An act to amend Sections 12500, 12501.1, and 12509.5 of, and to add Section Sections 12509.1 and 12509.6 to, the Business and Professions Code, relating to weights and measures.
SB 314 updates California’s weights-and-measures laws to create a more tailored regulatory framework for electric vehicle supply equipment (EVSE), or EV charging equipment that measures electricity sold as motor vehicle fuel. The bill would allow certain EVSE that has been audited or tested by a manufacturer or supplier to be used commercially for the remainder of the applicable inspection period, so long as it is sealed by a county sealer. It also creates a pathway for county sealers to ensure older EVSE installed before January 1, 2026, is initially placed in service and tested by January 1, 2027, and requires EVSE registration with the county where it is installed.
The bill amends Business and Professions Code provisions governing commercial weighing and measuring devices by expressly adding EVSE to the statutory framework and creating EVSE-specific rules for sealing, testing, registration, and enforcement. It would exempt EVSE installed for exclusive use at workplaces or residences from most chapter requirements until January 1, 2028, while preserving core accuracy standards, complaint-based testing authority, and county enforcement powers. It also directs the Division of Measurement Standards to issue statewide guidance, develop online forms and protocols, and consider optional compliance pathways such as factory auditing, factory- or supplier-registered service agencies, and other streamlined testing approaches. Counties would be allowed to sample-test EVSE, share data with the state, and use conditional authorization tools for certain non-meter-accuracy violations.
The available vote history suggests broad support in committee, with unanimous or near-unanimous votes at the recorded stages and no recorded opposition in the provided materials. The bill appears to have been viewed as a technical modernization measure that could reduce unnecessary repeat testing and improve consistency for EV charging infrastructure while maintaining oversight. The placement on the suspense file indicates fiscal or administrative considerations remained under review, but the overall committee posture was favorable.
The main policy tension is between streamlining EVSE deployment and preserving consumer protection through weights-and-measures oversight. Supporters appear to favor reduced duplication, manufacturer-based testing, and statewide consistency, while the bill still preserves county authority to tag, conditionally authorize, or seize noncompliant equipment and to test equipment in response to complaints. Potential points of concern include the shift toward factory auditing and optional compliance pathways, the administrative burden on counties to register and inspect older equipment by set deadlines, and the need for funding and equipment to support local enforcement. The bill’s exemption for workplace and residential EVSE may also raise questions about how much oversight should apply outside public charging settings.
