Mild-hybridisation of conventional powertrains is set to become commonplace over the next 5 years, providing a proportion of the on-cycle and real-world CO2 benefits of a high-voltage hybrid at a far lower cost. However, the majority of this focus is around engine-related systems such as belt starter-generators and electric-superchargers. Design studies and simulations have shown that hybridising elements of the transmission system can extend the efficiency gains of engine based mild-hybrid and stop-start systems. Equally important, is the potential for a transmission integrated electrical system to support value-adding features such as electric creep, engine-off coasting or electric torque support for manual or automated manual transmissions, which can either further justify or partially offset the additional cost of the hybrid system.

Battery Fires: Why They Happen and How They Happen was written to assist those interested in this type of incident understand how automotive fires develop, spread and the damage they cause, using both deductive and inductive reasoning. The main focus of the book resides in looking at differences in failure modes between DC and AC systems, general types of battery and electrical failure modes leading to fire, how to interpret electrical fire, determination of the primary failed part, and other skills the investigating engineer will require to perform technical failure mode analysis. However, some fires have consumed the evidence to the point where a determination cannot be made with any degree of certainty. In this instance, evidence will be quite limited, and the analysis will have its limitations and should be included in the discussion as such. In some cases, a “cause undetermined” report is all the evidence will support.

ARP5369B
These guidelines have been written to provide process information regarding the hot stamp method of marking wire identification directly on aerospace wires and cables. This document is not intended to encourage the use of hot stamp marking or to endorse the related process. This method of marking wire identification may be prohibited on any aerospace vehicle wiring that is required to conform to the provisions of MIL-W-5088L or AS 50881. Methods which do not deform wire or cable insulation, such as Ink Jet, Dot Matrix or UV Laser marking are encouraged as a means of minimizing the possibility of insulation damage, particularly on insulation constructions of less than 0.010 in wall thickness. In recognition that the present use of hot stamp wire marking is widespread and may continue for an extended period, the guidelines provided in this document are intended to provide process control information necessary to minimize the possibility of insulation damage.

1.0 SCOPE 1. This document contains procedures for testing performance of SMB-style electrical terminals, connectors and components for coaxial cable connection systems intended for road vehicle applications. These are often called FAKRA II designs. This specification does not apply to the Non RF portion of a Hybrid RF connection system. 2. The intent of this specification is to qualify sealed and unsealed RF connectors that operate at frequencies from DC to 6 GHz. The characteristic impedance of the SMB/FAKRA connection system is 50 ohms however this specification does not exclude the use of these RF connectors on non-50 ohm cables or systems. 3. This specification does not apply to single conductor wire or twisted pair connection systems. 4. This specification (along with SAE/USCAR 18) is designed to provide the mechanical and electrical data required to insure that assemblies from various manufacturers will perform reliably in actual conditions.

J1939DA
This document is intended to supplement the J1939 documents by offering the J1939 information in a form that can be sorted and search for easier use. The J1939 Digital Annex, introduced in August 2013, offers key J1939 technical data in an Electronic Spreadsheet that can be easily searched, sorted, and adapted to other formats. J1939DA contains all of the SPNs (parameters), PGNs (messages), and other J1939 data previously published in the SAE J1939 top level document. J1939DA also contains all of the SLOTs, Manufacturer ID Codes, NAME Functions, and Preferred Addresses previously published in the SAE J1939 top level and the J1939-71 document. J1939DA contains the complete technical details for all of the SPNs and PGNs previously published in the SAE J1939-71 document. It also includes the supporting descriptions and figures previously published in the SAE J1939-71 document.
