Joint Office Applauds Milestone Vote Advancing the J3400 EV Charging Standard

The Joint Office of Energy and Transportation is committed to making it easy for anyone to choose electric mobility, no matter what they drive or where they charge. In response to multiple automakers’ decisions to adopt the North American Connector Standard (NACS) developed by Tesla, the Joint Office has been actively collaborating with industry stakeholders to develop an open standard compatible with NACS, called J3400. The new SAE J3400 connector will ensure that any vehicle or charging equipment supplier or manufacturer will be able to use, manufacture, or deploy the connector and expands charging access for current and future EV drivers across the country. This standard is designed to ensure safe, reliable charging for drivers of all electric vehicles.

Recently, the SAE EV Coupler Task Force voted to establish the J3400 standard as a Recommended Practice, marking a significant step forward in the standardization process. This milestone brings the J3400 standard closer to official publication in a format that can be cited in regulations and used by manufacturers with confidence. The overwhelming support for the standard reflects the strong collaboration and dedication of industry partners to delivering an exceptional charging experience for consumers.

Completion of the SAE J3400 standardization process is expected soon. Once finalized, the standard will ensure that any vehicle or charging equipment supplier or manufacturer can use, produce, or deploy the connector, thereby expanding charging access for current and future EV drivers across the country. The Joint Office applauds the SAE EV Coupler Task Force for their work in recommending the standard and extends its gratitude to the SAE team for their ongoing partnership and support.
