At the Society of Automotive Engineers (SAE) 2009 World Congress, an update was presented of hybrid, plug-in hybrid and electric vehicle standards that are being revised by the SAE Hybrid Standards Committee.
Generally these standards, which are likely to be completed this year, are adopted by manufacturers of vehicles destined for North America and other markets.
These include:
- - J1711 Emission and Fuel Economy Testing: This has been designed to establish a uniform chassis dynamometer test procedure for hybrid-electric vehicles driven on public roads. Fuel economy and electrical energy usage will not be combined but instead fuel usage and watt-hours per mile will be stated separately. A “utility factor” component will also be retained to determine the fuel economy of a plug-in hybrid vehicle when in charge depleting mode.
- - J1772 Conductive charging: This establishes physical, electrical and performance requirements for both electric cars and plug-in hybrid vehicles. This includes the establishment of vehicle ventilation requirements; monitoring of equipment grounds; verification that a vehicle is present and connected; transmission of supply equipment current ratings; and allowing energising and de-energising of the charge current circuit. A separate standard will be developed for the European market.
- - J2464 Battery Pack and Capacitor Pack Safety: An overhaul of the current standard designed to determine the response of batteries to conditions or events beyond their usual operating range.
- - J2836 Vehicle-to-Charge Communication: This looks at the modes of communication between plug-in electric vehicles and the power grid for the purpose of transferring energy.
- - J2894 Charging Power Quality: This provides guidelines and standards for the quality of the charging voltage and current at the vehicle.
