Enhancing the Volt

I wanted to share some developments with you about our response to the NHTSA investigation into the Chevrolet Volt resulting from a fire several days after a severe crash test.
If you’ll remember, NHTSA began testing the Volt battery after one of the vehicles it crash tested in May caught fire three weeks after the test. Testing and analysis revealed the fire was the result of a minor intrusion from a portion of the vehicle into a side section of the battery pack. The intrusion resulted in a small coolant leak inside the battery, approximately 50 ml (one-quarter of a cup) of fluid.
Over the past few weeks, GM engineers have completed development and validation on a set of proposed enhancements and shared them with NHTSA staff.
We ran a series of internal tests and all successfully resulted in no battery pack intrusion or coolant leakage, thereby eliminating the chance for a post-crash electrical fire for this test condition.
