SAE International releases updates for two major EV charging documents
SAE J3072 Standard. SAE J3072 revisions establish requirements for a grid support inverter system function to better align with the significant changes to inverter requirements that were introduced by major revisions to IEEE 1547 and IEEE 1547.1. With this update, utilities or local jurisdictions can establish procedures for a site to be approved for the interconnection of plug-in electric vehicles (PEV) with onboard inverters based partially on testing and certifying SAE J3072 and other required standards.
The vehicle manufacturer (VM) or their designated agents will perform the analyses, inspections and tests to ensure that each inverter system model that is installed in one of their PEV models conforms to the requirements of SAE J3072. The VM or third-party testing body will issue a certificate of conformance to SAE J3072 for each authorized inverter system model.
SAE International announced a contract with a best-in-class contractor team, comprising Eonti, DigiCert and VerSprite to perform the technical development of the SAE Electric Vehicle (EV) Charging Public Key Infrastructure (PKI) project, an industry-led pre-competitive research project to strengthen EV charging system security. Public Key Infrastructure (PKI) is a system.
