University of Extrication: Hybrid & Electric Vehicle Identification

It was a simple email from the Society of Automotive Engineers (SAE). The message was short and sweet: “This notification is to inform you that document: J2990_201211 – Hybrid and EV First and Second Responder Recommended Practice has been...

A second HV shutdown primary disabling method that also complies with J2990 shuts down the HV system when a responder turns off the ignition at the key or power/stop button. A third, optional design that is acceptable allows cutting or disconnecting the cables of the 12-volt electrical system to shut down the high-voltage system as well. In this case, responder “cut labels” also have to be provided to indicate which cables need to be cut or disconnected to accomplish shutdown.

The fourth method of HV electrical system shutdown for a hybrid or electric vehicle involves designing the manual disconnect device to be accessible and designed for use by responder personnel without any special or unique electrical protective gear. These disconnects will all be orange in color to standardize their identification at crash scenes.

It would be well worth fire service agencies obtaining a copy of this new standard from the SAE and studying its contents. This is a major victory for the fire service; one that we need to understand better before we can realize how significantly this document will improve our safety and increase our efficiency at a hybrid or electric plug-in vehicle incident.

 

Task: The rescue team shall review the SAE J2990 document and determine how the requirements of this standard will impact responder safety and rescue operations at incidents involving a hybrid or electric plug-in vehicle. n
