The EV Charger Data and Reliability Standards establishes statewide EV charger data and reliability reporting requirements. This page provides the information on what data to submit and how to submit it. It also links to further background on the EV Charger Data and Reliability Standards.
In 2025, the California Energy Commission (CEC) adopted EV Charging Data and Reliability Standards to improve the reliability, transparency, and accessibility of California’s electric vehicle (EV) charging infrastructure. Information and the full text of these regulations can be found at EV Charger Data and Reliability Standards.
Entities operating applicable EV chargers are required to submit semiannual inventory reports to the CEC via the Data Submission Portal (DSP) Electric Vehicle Charging and Reliability Reporting (EV-CARR) application. These reporting requirements help the CEC maintain a comprehensive understanding of California’s charging network.
In addition to the inventory reporting requirement, applicable Direct Current Fast Chargers (DCFCs) must comply with a 97% uptime standard and submit reliability reporting. Applicable entities are required to submit semiannual reliability reports via the DSP EV-CARR, and may also report hourly reliability data to support uptime monitoring, maintenance tracking, and regulatory compliance activities.
