Weights and measures standards apply to half of all U.S. products and services, aiming to ensure consumers get what they pay for and products meet safety and quality expectations. The federal government sets uniform but nonbinding national standards, and leaves regulation and enforcement to states. Gas pumps have long been one of the most visible examples of enforcement, and the increasing strength of the electric vehicle market have led policymakers to consider the role of weights and measures standards for electric vehicle supply equipment (EVSE) (i.e., EV chargers).
California was an early adopter of applying weights and measures standards to EVSE, adopting its own standards even before permanent federal standards. This issue brief explores California's approach to weights and measurements standards for EV charging and early perspectives from conversations with select on-the-ground stakeholders, including county officials, charging service providers, and registered service agencies.
