Inverter Requirements for Class Eight Trucks - Truck and Bus

2017-02-07
CURRENT
J2697_201702
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.

Specific Gravity of Friction Material

2017-02-02
CURRENT
J380_201702
Specific gravity is a nondestructive test used as a quality control check of the consistency of formulation and processing of brake lining. The specific gravity and the range of specific gravity are peculiar to each formulation and, therefore, the acceptable values or range must be established for each formulation by the manufacturer. Specific gravity alone shows nothing about a materials in use performance. The specific gravity of sintered metal powder friction materials, particularly those which have steel backing members, is usually determined somewhat differently. Reference ASTM B 376.

Gogan Hardness of Brake Lining

2017-02-02
CURRENT
J379_201702
Hardness measurements are used as a quality control check of the consistency of formulation and processing of brake linings. Gogan hardness is nondestructive (the penetrator causes shallow surface deformation.). Gogan hardness method alone does not show anything about a lining’s ability to develop friction or to resist fade when used as a friction element in brakes. The hardness and the range of hardness are peculiar to each formulation, thickness, and contour; therefore, the acceptable values and ranges must be established for each formulation and part configuration by the manufacturer.

Lane Departure Warning Systems: Information for the Human Interface

2017-01-26
CURRENT
J2808_201701
The Lane Departure Warning (LDW) system is a crash-avoidance technology which warns drivers if they are drifting (or have drifted) out of their lane or from the roadway. This warning system is designed to reduce the possibility of a run-off-road crash. This system will not take control of the vehicle; it will only let the driver know that he/she needs to steer back into the lane. An LDW is not a lane-change monitor, which addresses intentional lane changes, or a blind spot monitoring system which warns of other vehicles in adjacent lanes. This informational report applies to OEM and after-market Lane Departure Warning systems for light-duty vehicles (gross vehicle weight rating of no more than 8500 pounds) on relatively straight roads with a radius of curvature of 500 m or more, and under good weather conditions.

Use Cases for Plug-In Vehicle Communication as a Distributed Energy Resource

2017-01-18
CURRENT
J2836/3_201701
This SAE Information Report establishes use cases for a Plug-in Electric Vehicle (PEV) communicating with an Energy Management System (EMS) as a Distributed Energy Resource (DER) which must be supported by SAE J2847/3. This document also provides guidance for updates to SAE J2847/2 to allow an inverter in an EVSE to use the PEV battery when operating together as either a DER or as a power source for loads which are not connected in parallel with the utility grid. Beyond these two specific communication objectives, this document is also intended to serve as a broad guide to the topic of reverse power flow.
