SAE releases interface standard for hybrid/electric vehicles
Warrendale, Pa. — SAE International has released a standard that provides a standard interface between plug-in hybrid and battery-electric vehicles, and electrical charging systems.
The Standard J1772, “SAE Electric Vehicle Conductive Charge Coupler,” details the general physical, electrical and performance requirements for the coupler, which consists of a connector and vehicle inlet. The standard defines a common electric-vehicle charging network, which should reduce cost and deliver increased convenience for owners of electric vehicles.
“By standardizing, you’re reducing costs and allowing everyone to use the same connector. All of the charging equipment you would pull up to in public would have identical connectors, so any vehicle could use one. It will be a consistent, reliable interface,” said Gery Kissel, chair of the SAE Hybrid Task Force, in a statement.
A production tooled coupler has passed testing by Underwriters Laboratories for safety and durability, according to SAE.
SAE International is a leading standards organization identified in the NIST Framework and Roadmap for Smart Grid Interoperability Standards for Interoperability Standards to Support Plug-In Electric Vehicles, and as collaborators for Energy Storage Interconnection guidelines.
SAE said the J1772 standard was developed by the SAE Hybrid J1772 Task Force in cooperation with major automotive OEMs and suppliers, charging equipment manufacturers, national labs, utility companies, universities and standards organizations from North America, Europe and Asia.
Touch user interfaces have made significant advances in the consumer electronics market particularly for mobile phones and notebook computers, opening the door for adoption in other applications including white goods, computer peripherals, medical equipment, and instrumentation. Synaptics made its debut in the home appliance market earlier this year with the launch of the Samsung Hauzen ZERO air conditioner.
Smaller distributors were the only ones to post sales gains in 2009. Interestingly, two of the five distributors that posted growth last year -- Interstate Connecting Components and Sherburn Electronics -- derive 100 percent of their sales from interconnect products. Both of them also target the military/aerospace industry. Here are the top 10 sales leaders by ICs, passives/electromechanical devices, interconnects and computer products as well as sales growth.
