The National Charging Experience Consortium (ChargeX) has released a report that recommends 26 common electric vehicle (EV) charging error codes to enable faster error reporting, diagnostics and resolution within the EV charging industry. Ultimately, the codes would improve the U.S. charging experience.
The ChargeX Consortium is a collaboration between U.S. Department of Energy national laboratories, EV charging industry experts, consumer advocates and other stakeholders.
The Recommendations for Minimum Required Error Codes report aims to reduce confusion between charger manufacturers, EV manufacturers and charging station operators, who currently use different messages to report similar errors. The common codes will simplify diagnostics when a charging session fails, improving EV charging network operations and charging experiences for drivers. Further, the codes will simplify diagnostics when a charging session faces an issue, streamlining EV charging network operations, reducing workforce training complexity and improving the charging experience for drivers.

Stellantis Ram brand has an answer to range anxiety: An onboard charger
One of the biggest reasons people cite when saying they won't buy an electric vehicle is range anxiety, the fear of running out of juice on the road with nowhere to recharge.
Stellantis' Ram brand may have an answer for that, especially for people who need a truck to haul or tow things. It's called the Ramcharger, a pickup that can travel 145 miles (235 kilometers) on electricity, with a 3.6-liter V6 gas-powered engine linked to a generator that can recharge the battery while the truck is moving.

Why AI and energy are the new power couple
Power systems are becoming vastly more complex as demand for electricity grows and decarbonisation efforts ramp up. In the past, grids directed energy from centralised power stations. Now, power systems increasingly need to support multi-directional flows of electricity between distributed generators, the grid and users. The rising number of grid-connected devices, from electric vehicle (EV) charging stations to residential solar installations, makes flows less predictable. Meanwhile, links are deepening between the power system and the transportation, industry, building and industrial sectors. The result is a vastly greater need for information exchange – and more powerful tools to plan and operate power systems as they keep evolving.
Falling battery prices push EVs to ICE price parity
Battery prices for electric vehicles fell 14% to $139/kWh in 2023 compared with $161/kWh in 2022, driven by lower raw material costs and global oversupply, according to price tracking data from BloombergNEF. BNEF predicts prices will continue to track falling raw material cost trends and drop to $133/kWh in 2024 and below $100/kWh by 2027, with EVs reaching price parity with combustion engine vehicles
ERCOT finds success with grid interconnection strategy
The Electric Reliability Council of Texas has added 14.2GW to its grid capacity in the last two years, more than any other US operator, using a "connect and manage" strategy that cuts out the need for network upgrades. Collect and manage focuses its interconnection request studies on the local upgrades that would be needed for a project to link with the grid.
The strategy allows generators to interconnect faster, more efficiently and at significantly less cost than any other model used in the US, according to Tyler Norris, an expert on renewables and doctoral student at Duke University.
EPRI Launches Groundbreaking Electric Transportation Grid Planning Tool
EPRI released eRoadMAP™, an interactive online resource intended to help electric power companies and industry stakeholders effectively plan for the power and infrastructure needed to serve light-, medium-, and heavy-duty electric vehicles (EVs).
This free and public tool allows users to explore how quickly EVs are expected in different regions, and identifies energy needs across the U.S. at the individual feeder level—where critical utility planning occurs.
This free and public tool allows users to explore how quickly EVs are expected in different regions, and identifies energy needs across the U.S. at the individual feeder level—where critical utility planning occurs.
To highlight both near-term and future energy needs, eRoadMAP incorporates the electrification plans of critical industry stakeholders as well as the future energy needs to support full electrification of the on-road transportation sector.
This tool is a work in progress and will continue to be updated and improved with additional data. Future plans for the mapping tool include integrating important demographic data and other planning resources to help identify and prioritize areas where transportation electrification-related investments can be made to address specific market needs, including major freight hubs, corridors and disadvantaged communities.
Conn. grid may need $2.3B upgrade to handle EV charging
“If the infrastructure is not built, I think that could become a serious impediment to customer adoption (of EVs),” said Digaunto Chatterjee, vice president of system planning at regional utility giant Eversource.
Eversource needs to build 14 new substations — at a cost of $100 million to $150 million each — to reliably serve the additional 4 GW of electricity needed to power EVs by 2040, Chatterjee said. Eight existing substations need to be upgraded, at a cost of $10 million to $25 million each, he added.
That’s an overall estimated investment of up to $2.3 billion to prepare for larger-scale EV adoption — costs likely to be borne, wholly or partially, by ratepayers.

Federal Highway Administration rule ties federal funds for road work to climate
The Federal Highway Administration has finalized a new rule that requires state transportation departments and local planning agencies to monitor greenhouse gas emissions from highway projects and set emissions reduction targets if the projects use federal funding. The rule is contentious because such regulations were omitted from the federal infrastructure law. "Every state has its own unique climate challenges, and every state ought to have the data, funding, and flexibility it needs to meet those challenges head on," said Transportation Secretary Pete Buttigieg.
