Electric Vehicle Power Transfer System Using a Three-Phase Capable Coupler
2022-07-26
CURRENT
J3068_202207
This document covers the general physical, electrical, functional, testing, and performance requirements for conductive power transfer to an electric vehicle using a coupler capable of, but not limited to, transferring three-phase AC power. It defines a conductive power transfer method including the digital communication system. It also covers the functional and dimensional requirements for the electric vehicle inlet, supply equipment connector, and mating housings and contacts. Moveable charging equipment such as a service truck with charging facilities are within scope. Charging while moving (or in-route-charging) is not in scope.

Primary Single Phase Nominal 120 VAC Wiring Distribution Assembly Design—Truck and Bus
2022-06-22
CURRENT
J2698_202206
This SAE Recommended Practice covers the design and application of primary on-board wiring distribution system harnessing for surface vehicles. This document is intended for single phase nominal 120 VAC circuits that provide power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off. The power supply comes from alternative sources such as land-based grid power, DC-AC inverters and auxiliary power generators. The circuits may also provide power to improve vehicle performance through charging batteries or operating cold-weather starting aids.

Coiled Electrical Cable - Truck and Bus
2020-02-25
CURRENT
J2222_202002
This SAE Standard establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers, and dollies for 12 VDC nominal applications. The component standards SAE J2394 (replaced SAE J1067) for cable and SAE J560 for connectors must be consulted to determine the complete performance and endurance requirements of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation, and inspection of these coiled electrical cables. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.

Seven Conductor Cable - Truck and Bus
2020-02-25
CURRENT
J1067_202002
This SAE Standard establishes the minimum construction and performance requirements for seven conductor 1/8-1/10-5/12 cable for use on trucks, trailers and converter dollies for 12 VDC nominal applications. Where appropriate, the standard refers to two types of cables (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications.

Seven Conductor Cable for ABS Power - Truck and Bus
2020-02-25
CURRENT
J2394_202002
This SAE Standard establishes the minimum construction and performance requirements for seven conductor 1/8-2/10-4/12 cable for use on trucks, trailers, and converter dollies for 12 VDC nominal applications. Where appropriate, the standard refers to two types of cables (Type F and S, described later in the standard), due to the variation in the performance demands of cables used in flexing and stationary applications. While the document’s title refers to ABS Power to differentiate the document from the SAE J1067 standard that it supersedes, the scope applies to both the primary green cable for powering ABS and lighting and the yellow auxiliary cable of the same construction.
