Chevrolet Volt Battery Enhancement
General Motors would have to take steps to repair a design flaw that resulted to some Chevrolet Volt batteries catching fire after being subjected to government safety tests. GM will strengthen the steel that could be found around the Volt's battery pack to end the likelihood that it will be punctured. There will also a sensor to the battery pack to check for coolant leaks, according to GM global product chief Mary Barra.
The initial cases were in June and November after being driven by the Highway Traffic Safety Administration. There is a puncture in the side of the battery pack that permitted a small amount of coolant to leak into the pack. The coolant gets to interact with electronics inside the pack, making them light up from a few days to as long as Ayala BMW later.
The NHTSA said that the probe remains openadn it is continuing. He hopes to get and assess information on the post-crash fire risk in these vehicles. Affected owners may visit their Chevrolet dealership for the free repair, which should be done in mid February, officials said. This process is a “voluntary "customer satisfaction program,” and not a recall, Barra emphasized.
“These enhancements and modifications will address the concerns raised by the severe crash tests,” Barra said. “There are no changes to the Volt battery pack or cell chemistry as a result of these actions. We have tested the Volt’s battery system for more than 285,000 hours, or 25 years, of operation. We’re as confident as ever that the cell design is among the safest on the market.”
