Download or read book Hybrid and EV First and Second Responder Recommended Practice written by Hybrid - EV Committee and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: XEVs involved in incidents present unique hazards associated with the high voltage system (including the battery system). These hazards can be grouped into 3 categories: chemical, electrical, and thermal. The potential consequences can vary depending on the size, configuration and specific battery chemistry. Other incidents may arise from secondary events such as garage fires and floods. These types of incidents are also considered in the recommended practice (RP). This RP aims to describe the potential consequences associated with hazards from xEVs and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred with an electrified vehicle. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement.Nickel metal hydride (NiMH) and lithium ion (Li-ion) batteries used for vehicle propulsion power are the assumed battery systems of this RP. These battery chemistries are the prevailing technologies associated with high voltage vehicle electrification today and the foreseeable future. The hazards associated with these specific battery chemistries are addressed in this RP. Other chemistries and alternative propulsion systems including Fuel Cells are not considered in this version of SAE J2990. Electrification of the vehicle industry is increasing at a rapid pace with many countries adopting goals for increasing the number of electrified vehicles (xEVs), including a US goal of having one million PHEV's on the road by 2015 and China's goal of 500 000 new energy vehicles in production by the end of 2015. This new propulsion technology in the automotive sector has raised concerns for these vehicles when involved in severe crashes because of the potential consequences associated with new hazards from the high voltage systems on board. While the high voltage system, under most crash situations, is likely to be protected and maintain electrical isolation from the rest of the vehicle, a rare but possible severe crash may compromise some of the safety features of the high voltage system. Due care needs to be taken when working around the electrified propulsion systems and components or charging systems, regardless of their condition.Some progress has been made in educating first responders about safe procedures when working around xEVs involved in crashes. However, considerable work is needed to develop common and consistent procedures for emergency responders across the automotive industry. In addition, further effort is needed to identify and address the consequences of the new hazards associated with xEVs for second responders consisting of tow, storage, repair and salvage personnel.

This book was released on 2018-11-14 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Federal Motor Vehicle Safety Standards - Electric-Powered Vehicles - Electrolyte Spillage and Electrical Shock Protection (US National Highway Traffic Safety Administration Regulation) (NHTSA) (2018 Edition) The Law Library presents the complete text of the Federal Motor Vehicle Safety Standards - Electric-Powered Vehicles - Electrolyte Spillage and Electrical Shock Protection (US National Highway Traffic Safety Administration Regulation) (NHTSA) (2018 Edition). Updated as of May 29, 2018 NHTSA is issuing this final rule to amend Federal Motor Vehicle Safety Standard (FMVSS) No. 305, "Electric-powered vehicles: Electrolyte spillage and electrical shock protection," to adopt various electrical safety requirements found in Global Technical Regulation (GTR) No. 13, "Hydrogen and fuel cell vehicles," and other sources. This final rule updates FMVSS No. 305 using modern and harmonized safety requirements and facilitates the introduction of new technologies, including hydrogen fuel cell vehicles (HFCVs) and 48-volt mild hybrid technologies. This final rule is a deregulatory action. It imposes no costs and adjusts FMVSS No. 305 to give more flexibility to manufacturers not only to use modern electrical safety designs to produce electric vehicles, but also to introduce new technologies to the U.S. market. To expand FMVSS No. 305's performance requirements beyond post-crash conditions, NHTSA adopts electrical safety requirements to protect against direct and indirect contact of high voltage sources during everyday operation of electric-powered vehicles. Also, NHTSA adopts an optional method of meeting post-crash electrical safety requirements, consistent with that in GTR No. 13, involving use of physical barriers to prevent direct or indirect contact (by occupants, emergency services personnel and others) with high voltage sources. This book contains: - The complete text of the Federal Motor Vehicle Safety Standards - Electric-Powered Vehicles - Electrolyte Spillage and Electrical Shock Protection (US National Highway Traffic Safety Administration Regulation) (NHTSA) (2018 Edition) - A table of contents with the page number of each section

Download or read book Electric Vehicle E Vehicle Crash Test Lab Safety Guidelines written by Impact and Rollover Test Procedures Standards Committee and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special risks associated with conducting crash tests on E-Vehicles can be divided into two main categories; 1) thermal activity inside the battery (resulting from electrical or mechanical abuse) may lead to energetic emission of harmful and/or flammable gases, thermal runaway, and potentially fire, and 2) the risk of electrocution. Procedures to ensure protection from all types of risk must be integrated into the entire crash test process. This informational report is intended to provide guidance in this endeavor using current best practices at the time of this publication. As both battery technology and battery management system technology is in a phase of expansion, the contents of this report must then be gaged against current technology of the time, and updated periodically to retain its applicability and usefulness.The scope of this document is to provide an understanding of the risks and an overview of the techniques established to reduce the likelihood that an event would cause harm to laboratory personnel and/or property. A laboratory considering E-Vehicle crash testing should work closely with the E-Vehicle manufacturer to identify and understand the risks associated with shipping and handling of their vehicle (pre and post-crash), storage of the vehicle (pre and post-crash), battery system diagnostics procedures, and operation of the vehicle. There are special risks associated with the destructive testing of E-Vehicles, such as pure electric vehicles (EV's), hybrid electric vehicles (HEV's), and plug-in hybrid electric vehicles (PHEV's). This information report is intended to inform crash test personnel and facility managers of the risks, and some countermeasures to help mitigate the risks to lab personnel safety, the facility, and the equipment used in the testing. This report is not intended as a stand-alone procedure for E-Vehicle crash test safety, as the technology is still evolving and cannot be represented fully in this context.

Download or read book Incidence Rates of Pedestrian and Bicyclist Crashes by Hybrid Electric Passenger Vehicles written by Jingshu Wu and published by Createspace Independent Pub. This book was released on 2011-10-31 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hybrid electric (HE) passenger vehicles first became available to consumers in 2000, and their numbers as well as their proportion of the passenger vehicle fleet have risen every year since their introduction. Advocacy groups have raised pedestrian safety concerns regarding HE vehicles because a vehicle using the electric motor may be relatively quieter than a vehicle using an internal combustion engine (ICE) and may not emit the sounds that non-motorists rely on for warning as vehicles approach them. In 2009 the National Highway Traffic Safety Administration released the report “Incidence of Pedestrian and Bicyclist Crashes by Hybrid Electric Passenger Vehicles” with the finding that an HE vehicle was two times more likely to be involved in a pedestrian crash than an ICE vehicle in situations involving low-speed maneuvers (Hanna, 2009). This report aims to update the previous report with more data by adding additional years of State crash files as well as by increasing the number of States included in the analysis from 12 to 16.
