Volt’s Battery Issue: Finally Fixed?

Wednesday, January 11, 2012 | comments

Lately General Motors was having some sort of problem with Chevrolet Volt and yes it’s the issue on batteries. However after a few claims that there problem is at hand of the the guys over at General Motors have finally come up with a solution. The battery pack received some mild structural modifications the guys over at Chevrolet say will make all of the necessary difference. GM will add structural reinforcement that better protects the battery pack from puncture or a coolant leak in a severe side crash, according to Mary Barra, GM's senior vice president of global product development. GM is also planning to add a sensor in the reservoir of the battery coolant system to monitor coolant levels and add a temper-resistant bracket to the top of the battery coolant reservoir, which definitely help in increasing the durability of the battery. In addition to that this  will help prevent potential coolant overfill as well as protects the batteries from getting damaged. Also, in the future technicians will drain batteries of their charge following severe crashes. These repairs will just add about three pounds to the weight of the vehicle. GM concluded that the fires resulted from a coolant leak that occurred when the battery pack in the vehicle was punctured during the tests of severe side crashes.

More importantly the National Highway Traffic Safety Administration has also determined and testify about the said issue. The battery fires happened hours to weeks after the tests as the coolant leaked and eventually created a short circuit. Good thing they have end up with a fix!
