State Administration of highway traffic safety (NHTSA)
It has been announced that this is the process of testing lithium
Ion batteries used in the Chevrolet Volt, a GM electric vehicle.
Earlier, after a car in the test facility parking lot caught fire, concerns were raised during the test on June and 9.
The fire was fierce, causing damage to several other cars parked nearby.
In May, NHTSA collided with a Volt, causing it to experience a serious side collision, causing serious damage to its body and causing internal damage to the battery.
In the accident, the coolant line was also broken.
The crashed Volt was transferred to the test facility parking lot in Burlington, Wisconsin for long-term storage.
On June, the battery caught fire about three weeks after the initial collision.
In the test, NHTSA used several identical battery packs to recreate the side crash used in a possible crash.
These collisions are intended to mimic narrow objects, such as side effects that can persist when hitting a tree or pole.
In the first collision, the battery did not change after the collision.
Second, the battery was registered at a higher temperature immediately after the collision, but it didn't really catch fire until a few hours later.
The third battery did not change at first, but then caught fire.
The battery for the last test showed some smoke and sparks but was not actually on fire.
NHTSA has not issued any warnings or recalls related to Volt or L-
The ion batteries they use at this time, but will continue to test them.
After learning about the tests on Friday, GM issued a statement reiterating the safety of the Volt during "normal operation" and after a serious crash.
Both GM and NHTSA agree that there is no Volt fire report under normal working conditions or on the road.
News about these safety issues could further damage the electric car industry, which has been struggling with sales lag.
GM is expected to sell nearly 10,000 vehicles by the end of this year, but less than half of that target.
Its direct competitor, Nissan Leaf, is selling twice as much as Nissan Leaf.
S. President Barack Obama wants electric vehicles to play a bigger role in national travel, proposing that 1 million cars will be on the road by 2015, so that the United States can reduce its exposure to foreign oil.
