Product Code:SAE AS6480
Title:Tie Down, Cargo, Aircraft, Type C-2
Issuing Committee:Age-2a Cargo Handling Committee
Scope:This specification covers one type of aircraft cargo tie down, designated Type C-2.Product Code:SAE J2847/6
Title:Wireless Charging Communication between Plug-in Electric Vehicles and the Utility Grid
Issuing Committee:Hybrid - Ev Committee
Scope: This SAE Recommended Practice J2847/6 establishes signals and messages for communication between plug-in electric vehicles and the electric power grid, for wireless energy transfer.This is the 1st version of this document and completes step 1 effort that captures the initial objectives of the SAE task force. The intent of step 1 was to record as much information on 鈥渨hat we think works鈥?and publish. The effort continues however, to step 2 that allows public review for additional comments and viewpoints, while the task force also continues additional testing and early implementation. Results of step 2 effort will then be incorporated into updates of this document and lead to a republished version.
