California has put reliability and data-sharing rules in place for EV chargers supported by state agencies or regulated utilities, after laws passed in 2022 and 2023 directed the California Energy Commission to act. The rules include a requirement for certain new public fast chargers to support OCPP 2.0.1, but repair experts say gaps in data and coordination still leave charging failures difficult to diagnose and prevent.
California has put new reliability and data-sharing rules in place for EV chargers funded by state agencies or regulated utilities, following laws passed in 2022 and 2023 that directed the California Energy Commission (CEC) to set standards. The rules include an open communications requirement for certain new public fast chargers, but repair and charging-industry experts say important information and coordination gaps remain.
One central requirement applies to publicly funded direct-current fast chargers installed on or after September 28: they must support OCPP 2.0.1, the latest version of the Open Charge Point Protocol. The protocol 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 shuts down, rather than leave chargers stranded.
The rules grew out of state laws passed in 2022 and 2023, which instructed the CEC to enforce reliability and data-sharing standards for charging installers receiving money from state agencies or regulated utilities. The source report says the regulations are now in place, after a process that took several years. The requirements are tied to public funding; the material does not establish that they cover every charger in California.
Some industry participants question whether the requirements will improve service. An employee of a large charging network, whose name was not provided in the report, described the regulations as “largely an onerous data-reporting exercise” and said they would not “move the needle on reliability.” Other stakeholders argue that performance information is necessary to check whether publicly funded equipment works as intended and to identify faults.
Public Funds Bring Reliability Conditions
Charger reliability affects whether drivers can depend on public charging, particularly when they cannot charge at home or need a fast charger during a trip. California has more EVs than any other state, according to the source report, giving the state a large stake in whether public infrastructure works consistently. A charger that is installed but out of service, or that fails during payment or vehicle communication, does not provide the service drivers expect.
The rules address two connected problems: collecting information about charger performance and reducing dependence on a single software provider. Common communications standards may make switching providers more feasible, while data reporting can help agencies and operators see how equipment performs. Those measures do not by themselves guarantee that a charger will be repaired quickly or that every step in a charging session will work. The rules’ practical effect will depend on implementation, access to useful data, and coordination among hardware, software, vehicle, payment and repair companies.
The policy also reflects a trade-off. Reporting and technical requirements can add work for charging companies, as the anonymous network employee argued. In return, the state is seeking greater accountability where public money supports the infrastructure. The source material does not provide performance results showing whether the new standards have already reduced outages.

From Federal Standards to State Action
The report places California’s rules against a broader shift in responsibility. The Biden administration attached reliability requirements to a $5 billion federal EV-charger program, helping bring the issue into focus. The report says federal leadership later weakened under the Trump administration, leaving states to take on more of the work; it does not provide details here about specific federal actions or their effects on California projects.
California’s policy effort followed the state laws enacted in 2022 and 2023. The CEC was tasked with standards covering reliability and data sharing for installers receiving specified public or utility funds. The resulting rules combine regulatory requirements with a separate effort to help companies test and troubleshoot equipment together.
That effort includes the Capital Charge Yard, a Sacramento testing lab that opened in August and received a $4 million CEC grant, according to the report. Participating companies include ABB, ChargePoint, EVgo, Hubject, Rivian and Tesla. The nonprofit California Energy, Power, and Innovation Collaborative manages the facility and already hosts training for EV and charger technicians. It is intended to test how equipment works and support training, rather than replace the CEC’s regulatory role.
“They have very strict requirements.”
— Michael Bakunin, CEO of EV-charging software vendor Epic Charging
Data and Repair Gaps Persist
It is not yet clear from the available material how much the new requirements will change charger uptime, repair times or the success rate of charging sessions. The report gives no before-and-after performance figures, compliance results or timetable for evaluating the rules’ impact.
Terry said repair crews still do not have access to all the information they need to identify what has gone wrong. She also said there are no clear rules forcing hardware and software companies to manage handoffs effectively across charger diagnostics, communication with vehicles and payment authorization. Those gaps can cause sessions to fail even when a charger is physically present and operating.
The source does not specify how the CEC will measure reliability under the rules, what penalties apply for noncompliance, or whether the requirements will later expand to chargers outside the covered funding programs. The reported concerns about administrative burden also remain a point of disagreement among stakeholders.
Testing and Enforcement Ahead
The next test is whether the requirements produce usable performance data and whether covered chargers can meet the OCPP standard in practice. The CEC is responsible for enforcing the rules, but the source material does not give a schedule for compliance reviews or public reporting on results.
At the Capital Charge Yard, the nonprofit managing the facility plans to use its testing and training work to help companies check that chargers and related systems function as expected. That work could complement the state’s rules by giving companies a place to identify compatibility problems, although the report does not describe a published testing schedule or results so far.
For drivers, the key evidence will be whether publicly funded chargers become easier to use and less likely to fail, and whether faults are diagnosed and repaired more quickly. The state’s standards set requirements; their effect on everyday charging remains to be demonstrated.
Key Questions
What did California change for public EV chargers?
The state put CEC rules in place covering reliability and data sharing for chargers supported by state agencies or regulated utilities. One requirement says covered public DC fast chargers installed on or after September 28 must support OCPP 2.0.1.
What is OCPP 2.0.1?
It is a version of the Open Charge Point Protocol, a technical standard that allows EV chargers and network-management systems made by different vendors to communicate. The aim is to make it easier to change software providers if needed.
Do the rules cover every EV charger in California?
The source describes requirements for charging installers receiving money from state agencies or regulated utilities. It does not say that the rules apply to every charger in the state.
Will the new standards stop chargers from breaking down?
That has not been established. The standards address data sharing and technical compatibility, but repair experts say diagnostic information and coordination between companies remain incomplete. The report provides no results showing a reduction in outages.
What is the Capital Charge Yard?
It is a Sacramento testing lab that opened in August with a $4 million CEC grant. Managed by the California Energy, Power, and Innovation Collaborative, it brings together EV and charging companies for testing and technician training.
