Third Chevrolet Volt fire could bring about new EV regulations
TorqueNews had a chance to speak with Rob Peterson of General Motors who confirmed that the Chevrolet Volt "involved" in the two residential fires were burned in the fire but the Fire Marshalls in both cases ruled that the Volt was not at fault for the fires themselves. That being said, it was merely a coincidence that the cars which caught fire in those garages were Volts.
The most recent issue occurred when a 2011 Chevrolet Volt that had been used for crash testing caught fire while sitting in an NHTSA overflow lot – three weeks after the car had been wrecked during testing. The concern by the NHTSA is that when these lithium ion batteries are damaged in an accident, there is an increased risk of fire hazards to the first responders who arrive to assist with the accident along with those who handle the vehicle after the wreck, such as tow truck drivers and owners of the salvage yards where these wrecked EVs are sent.
General Motors points out that they recommend that when charged, the lithium ion battery in the Chevy Volt should be drained as soon as possible after the accident and after the NHTSA performed the crash testing on the Volt, the battery should have been drained. Right now, General Motors sends a team of specially trained technicians to drain the Voltec battery but the technology to do this could be available within the next year to dealerships around the country. Also, General Motors has worked with the National Fire Protection Agency to train over 10,000 first responders who know how to properly deal with wrecked. GM's Rob Peterson explained the following about the training for these first responders: "Their protocol is to isolate the energy in the battery at the scene of an accident. This is accomplished by simply pulling the manual service disconnect or cutting the wires in a specific location. This action allows first responders to safely do their job. The vehicle can then be removed and de-energized elsewhere - eventually by a dealership, salvage yard or other entity who takes possession of the vehicle."
