California has put reliability and data-sharing rules in place for EV charging projects funded by state agencies or regulated utilities, following laws passed in 2022 and 2023. The rules include a requirement for certain new publicly funded fast chargers to support a common communications standard, but repair experts say data access and coordination problems remain.
California has put new reliability and data-sharing rules in place for electric-vehicle chargers funded by state agencies or regulated utilities, a step aimed at reducing breakdowns and making it easier to keep public charging stations operating. The requirements follow state laws passed in 2022 and 2023, and include a communications standard for certain publicly funded fast chargers installed from September 28 onward.
The California Energy Commission (CEC) is responsible for enforcing the standards. One requirement is that covered direct-current fast chargers installed on or after September 28 support OCPP 2.0.1, a protocol that lets charging equipment and network-management systems from different vendors communicate. The stated aim is to make it easier to change software providers if a manufacturer or network operator stops doing business, rather than leaving equipment unusable.
Industry participants say the rules address a real problem but will not, by themselves, resolve all causes of failed charging sessions. Kameale Terry, CEO and co-founder of charger repair company ChargerHelp, said repair crews still lack some of the information needed to diagnose faults. She also pointed to gaps in how hardware, software, vehicle communications and payment systems coordinate when a session fails.
The state is also supporting practical testing. The CEC awarded $4 million to the Capital Charge Yard, a Sacramento testing facility that opened in August. The site involves companies including ABB, ChargePoint, EVgo, Hubject, Rivian and Tesla. Its nonprofit operator, the California Energy, Power, and Innovation Collaborative, already offers technician training and says the facility can test whether chargers work as expected before deployment.
Rules Meet Repair and Testing Gaps
Reliable public charging affects whether drivers can depend on an EV for routine travel, particularly when they cannot charge at home. A charger that appears available but fails during payment, vehicle communication or power delivery can disrupt a trip and weaken confidence in the network. California has a large EV market, so the performance of its charging infrastructure has consequences for drivers, public agencies and companies building or maintaining stations.
The rules pair public-funding conditions with a shared technical protocol. That may reduce the risk of equipment becoming stranded when a vendor exits, while required performance data can help agencies monitor publicly funded projects. But the standard is not a guarantee that every charging session will work: experts cited in the report say diagnostic information and coordination across systems remain incomplete. The Capital Charge Yard offers a separate route to address those issues through testing and training.
For readers, the distinction matters: the state has established requirements and funded a testing effort, but the development does not establish that charger reliability has already improved. Results will depend on compliance, the quality and usefulness of reported data, and whether providers can resolve failures across equipment and software systems.

How California Reached the New Rules
California’s effort follows a wider push to tie public money to charger performance. The source report says the Biden administration attached reliability requirements to its $5 billion federal EV-charger program, while subsequent federal leadership changes left states to take on more of the work. The report does not detail the effect of those changes on specific projects.
In California, laws passed in 2022 and 2023 directed the CEC to establish reliability and data-sharing standards for charging installers receiving money from state agencies or regulated utilities. The rules took years to put in place. Supporters argue that performance information is needed to check whether publicly funded chargers are serving the public; an industry representative quoted in the report criticized the requirements as burdensome reporting that may not improve reliability.
The OCPP requirement is one part of the effort. Obrie Hostetter, director of fleet decarbonization programs at the Center for Sustainable Energy, said interoperability could help keep chargers operating if a provider goes out of business. EV-charging software executive Michael Bakunin said meeting the requirements was difficult, though he said they could help future charger owners change software providers.
“They have very strict requirements.”

What the Standards Cannot Yet Resolve
It is not yet clear whether the new requirements will produce measurable improvements in charger uptime or how the CEC will assess performance over time. The source report gives no statewide reliability baseline, results from the new rules, or schedule for publishing performance findings.
Repair specialists also say data access remains incomplete and that responsibilities for managing handoffs among chargers, vehicles, software and payment systems are not clearly defined. The report does not specify how the CEC’s rules address each of those operational failures or what enforcement actions will follow noncompliance. Nor does it provide a count of chargers covered by the new protocol requirement.
Testing and Compliance Ahead
The next test is whether covered projects comply with the CEC standards and whether the information gathered helps agencies and repair teams identify recurring faults. The Capital Charge Yard is expected to support testing and technician training, but the report does not give a timetable for public results or set out a formal evaluation plan.
California’s approach now combines funding conditions, interoperability requirements and a testing facility. Whether that mix improves the experience for drivers will become clearer as more covered chargers are installed and operated, and as agencies and industry participants report on failures and repairs.
Key Questions
What did California change for publicly funded EV chargers?
The California Energy Commission has put reliability and data-sharing rules in place for chargers funded by state agencies or regulated utilities. The requirements include technical standards for certain new fast chargers.
What is OCPP 2.0.1?
It is a communications protocol that lets EV chargers and network-management systems from different vendors exchange information. The state’s requirement is intended to make it easier to switch software providers if needed.
Which chargers must support OCPP 2.0.1?
According to the source report, the requirement applies to publicly funded direct-current fast chargers installed on or after September 28. The report does not provide a total number of chargers covered.
Will the new rules guarantee that chargers work?
No such guarantee is established in the report. Experts say gaps in diagnostic data and coordination among charging hardware, software, vehicles and payment systems remain.
What is the Capital Charge Yard?
It is a Sacramento testing facility that opened in August with a $4 million CEC grant. Its operator says the site can test chargers and train technicians; the report does not yet give results from its testing work.
