because it Is interested in new energy vehicles, so I’m often asked clutching problems, the most asked question Is, “do electric Car safety ? “I know the electric Car” black hIstory “a lot, but also a lot of online rumors. Electric Car in the end it safe? Look at the several won five-star safety assessment models talk about it.
Speaking of safety problems electric vehicles, have to say that several “fire.”
from foreign to domestic Volt Wal Landa BYD electric taxi from electric buses have had to Issue fire. However, these are not fire their own problems electric vehicles, fuel vehicles also exIst spontaneous combustion, collIsion fire.
then the electric Car caught fire so how are everyone’s attention? The reason Is that we do not trust the internal electric vehicle batteries.
Is the electric vehicle battery hundreds of various cell together, together with the battery management system, in the Car. A small cell phone battery can explode, not to mention there are so many cell Car?
high temperature, rain, collIsion, these cells can make every minute heroic martyrdom. Wait a minute, you say thIs really Is Car?
In fact, the electric Car’s battery before the factory after the crush, puncture, drop, vibration and other tests Will detect a short circuit in the case of whether the fire. So the battery pack Is not fragile as you might think, but electric Cars at the factory Will do a series of tests to ensure the safety.
These tests are not trust you? Then the third-party testing you always believe me. There are so several electric vehicles, which won praIse at home and abroad five-star safety rating agencies testing.

Insurance Institute for Highway Safety (IIHS) recently publIshed a report on several new energy vehicles in the crash test, Tesla MODEL S did not get TOP SAFETY PICK +, that Is, the highest safety evaluation.
The reason Is that 25% of Tesla MODEL S frontal offset crash test and did not receive test headlight excellent evaluation. 25% 25% frontal offset crash test, because of poor webbing bound, dummy body from moving too far forward, such that the head hits the steering wheel through the airbag, and the dummy sensor indicates the process the right leg may be injured. According to thIs response Tesla, it has to communicate with the IIHS, aspects of tied belt, light irradiation angle of MODEL S Will participate in the test and re-adjusted.
Insurance Institute for Highway Safety (IIHS) Is the world’s most authoritative standard Is the most stringent third-party vehicle safety testing organization, these tests are more stringent than the average crash test conditions, the angle Is more tricky.
increasing test items and test difficulty evaluation system, mainly in order to restore the vehicle after the accident the most realIstic situation. In fact, E-NCAP and C-NCAP improved every year, in order to provide consumers with better crash safety authority index. Five year only represent the past, present hope of electric Car manufacturers can improve the lot of the safety performance of vehicles, to provide consumers with protection.
Comments: As TECHNOLOGYSurgery and matures rapidly changing technological innovation, five-star safety assessment system Will continue to improve. Safety performance of electric vehicles can not be ignored, in the hope that the major manufacturers of electric Car Care subsidies, sales at the same time, all the time and can be constantly updated security configuration vehicle, Will star in the end.
