This SAE Standard establishes the minimum performance and endurance requirements for coiled electrical cables used for hookup between trucks, trailers and dollies. 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.

This SAE Recommended Practice document covers the general guidelines for conductive power transfer of high voltage Direct Current (DC) power between OEM commercial truck chassis electrical systems and electrically powered body accessory equipment. The OEM chassis can have an EV drive train or be a hybrid chassis with or without a connection for traditional mechanical PTO. The chassis can include use of range extension systems. Voltage levels are defined as greater than 60VDC and include typical EV chassis voltage ranges up to and including 1200VDC . It also covers the functional requirements for the connection systems, body builder communication modes including diagnostics, suggested operational modes, system interlocks and isolation management. The scope of the ePTO physical electrical connection will be limited to a recommendation of the interface concept, space claim and service features and will leave connector features and design open for future definition.

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.

This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for circuit breakers in ratings from 50 to 200 A. The document covers externally mounted automatic reset and manually reset types of circuit breakers for low voltage DC operation (typically 50 V or less).

The recommended practice describes a design standard that defines the maximum recommended voltage drop of the starting motor main circuits, as well as control system circuits, for 12/24-V starter systems. The battery technologies used in developing this document include the flooded lead acid, gel cell, and AGM. Starting systems supported by NiCd, Lithium Ion, NiZn, etc., or Ultracaps are not included in this document. This document is not intended to be updated or modified to include starter motors rated at voltages above the nominal 24-V electrical system. The starter is basically an electrical-to-mechanical power converter. If you double the available battery power in, you double the peak mechanical power out and double the heat losses. This means that we have to pay special attention to how battery power changes when we change the battery voltage and the effects it may have in overpowering the cranking system.

This document is an optional addition to SAE J3068 that adds additional communications (using LIN-CP) between the EV and SE that provide capabilities valuable to commercial fleets. These include the ability of the EV and SE to exchange unique identifiers, to establish which EV is connected to which SE, and to specify requirements for the next trip.

This SAE Recommended Practice is intended to describe the application of single-phase DC to AC inverters, and bidirectional inverter/chargers, which supply power to ac loads in Class heavy duty on-highway trucks (10K GVW). The document identifies appropriate operating performance requirements and adds some insight into inverter selection. This document applies to factory and after-market installed DC-to-AC inverter systems (Including inverter chargers) providing up 3000 W of 120 VAC line-voltage power as a convenience for operator and passenger use. Such inverters are intended to power user loads not essential to vehicle Operation or safety (e.g., HVAC, TV, microwave ovens, battery chargers for mobile phones or laptop computers, audio equipment, etc.). Systems incorporate the inverter itself as well as the input, output, control, and signal wiring associated with the inverter.
