The traffic police department said: At present, the accident is still under investigation and will be handled fairly in strict accordance with the law, and the accident-related progress will be notified in time. After the accident, some media found that a man and three women on a red sports car went to OCT Hospital near the incident to register for treatment. The man does not match the appearance characteristics of the person who surrendered himself and is suspected to be a "top bag".

20 12 on may 27th, Shenzhen traffic police released the progress of a major traffic accident in the early morning of may 26th, saying that the driver Hou was not the owner of the red car and was drunk and speeding. The Shenzhen Municipal Party Committee and the Municipal Government instructed that the cause of the accident should be found out quickly and the aftermath of the accident should be done well. In the early morning of the 27th, Shenzhen traffic police launched a "tiger fight" campaign for traffic rectification.

The Shenzhen traffic police department said that the man had nothing to do with the traffic accident. I just entered OCT Hospital at about 3: 57 on the 26th because I accidentally fell down nearby. Hou Moumou, the driver of the accident, abandoned the car and fled after the accident. After crossing the isolated green belt in the middle of the road, he crossed the road and arrived at the lawn of the green belt on the south side of Binhai Avenue. He called his male friend Wu Moumou and asked Wu Moumou to take him home. At about 4 o'clock that day, Wu Mou took a Guangdong BK8X87 taxi near Nanshan Happy Valley, picked it up and sent it to Dameisha Yacht Club. Enter room 85 10 to rest and change clothes. The traffic police department also showed video clips at the press conference. 20 12 At 2 o'clock in the afternoon on June 2, a female netizen made a red eye-catching banner in front of the Futian Traffic Police Brigade to publicly apologize to the police who handled the 5.26 coastal traffic accident in Shenzhen.

The banner says, dear: I'm sorry! I am also a young netizen who once questioned your "unfairness, unfairness, injustice, ignorance, fraud and top package" when investigating the 5-26 drag racing case. Now I sincerely apologize to you publicly! You are wronged! You have worked hard! Charm Shenzhen will be more charming because of your charm! !

It is understood that after the woman appeared, the police on duty of Futian Traffic Police Brigade welcomed her to the office to thank her. At the same time, the duty leader of the brigade repeatedly told the reporters present: "This is by no means an arrangement."

Some netizens said that this female netizen may want to take the opportunity to become famous, because a normal person can't be so affected.

Doubt: 1. Why are dozens of cameras in mangrove section of Binhai Avenue broken for no reason?

2. Why did the Shenzhen police jump to conclusions about the accident prematurely, and even some policemen patted their chests to ensure that the facts were unknown? Can this be guaranteed?

In a recent live video, a woman claimed "Don't say I'm driving". Shenzhen police can't explain this doubt. I hope that the Shenzhen police will be cautious in their words and deeds, cherish the trust of the people, establish a glorious image for our party and cherish feathers. ...

Summary of Shenzhen 5.26 accident

On the morning of August 3rd 10: 30, Shenzhen Development and Reform Commission held a press conference at the Convention and Exhibition Center. Wu Zhixin, an expert in accident appraisal, announced the "Quality Appraisal Conclusion" at the briefing of the "5 26" major traffic accident pure electric taxi quality appraisal conclusion, indicating that E6 "has no defects in vehicle safety design".

According to experts' calculation, the speed of the accident GT-R on Binhai Avenue was 242km, the impact speed was 183- 193km, the speed of the electric taxi was 8 1-83km, the collision speed between the tail and the trunk of the electric car was 64-67km, and the tail of the electric car was sunken1. Experts say that if there is no battery pack, the back seat may even be cut off.

Experts also said that the electric taxi hit the tree for the second time, causing far more damage to passengers than the first time, and the battery did not explode.

According to the investigation by the expert group, among the 96 batteries of electric taxis, 24 were short-circuited and caught fire, and the rest were intact. The cause of the fire was that after two violent impacts, some batteries were damaged and short-circuited to generate an arc, which ignited interior materials and some batteries. Experts also said that the burning battery plates were kept clean and distinct, and there was no bursting phenomenon.

The final conclusion is that the electric vehicle has not exploded and there are no defects in the safety design of the whole vehicle. The expert group concluded that the mechanical injuries suffered by three passengers in two collisions caused fatal injuries. It is confirmed that e6 electric taxi is a product in the national announcement of new automobile products, which not only passed the vehicle collision safety of relevant national testing institutions, but also met the higher requirements of American testing standards.

Conclusion: 1, the form and severity of the accident are extremely rare; 2. The degree of mechanical injury to passengers seriously exceeds the tolerance limit of human body, causing fatal injury; 3. 1/4 battery will not explode if it burns in short circuit; 4.e6 pure electric taxi has passed the vehicle safety inspection of relevant national institutions, and there are no defects in the safety design.

On the morning of August 3, 20 12, Shenzhen "5.26" major traffic accident pure electric taxi quality appraisal expert group held an appraisal conclusion briefing. Wu Zhixin, deputy director of China Automotive Technology and Research Center and head of the 526 accident quality appraisal team, said that the BYD e6 electric taxi destroyed in the "5.26" accident "has no defects in the safety design of the whole vehicle".

20 12 In the early morning of May 26th, a serious collision accident occurred between a Nissan GTR sports car and a BYD e6 taxi on the mangrove section of Shenzhen Binhai Avenue, resulting in three deaths, damage to the e6 taxi and fire. Shenzhen Municipal Government immediately launched the "5.26" major traffic accident pure electric taxi quality appraisal.

At the beginning of June, Shenzhen Metrology and Quality Inspection Institute (referred to as Shenzhen Quality Inspection Institute) organized the quality appraisal work authorized by the superior quality supervision department according to law, and invited 13 domestic industry authorities in the fields of electric vehicles and power systems, parts safety, structural safety, collision safety, electronic and electrical safety, electric vehicle power batteries, automobile traffic accident appraisal, fire investigation, and substance combustion characteristics to form an expert group. Special quality appraisal work was carried out in five aspects: vehicle, vehicle collision, power battery, fire and traffic accident appraisal, including 3 experts in Guangdong Province and 0 experts from outside Guangdong Province 10.

Experts come from China Automotive Technology Research Center, Highway Research Institute of Ministry of Transport, tianjin fire Research Institute of Ministry of Public Security, Guangdong Fire Corps, North Vehicle Research Institute, Shenzhen Metrology and Quality Inspection Institute and other technical institutions. The expert group officially carried out the quality appraisal of pure electric taxis on June 1 1, 1965. The quality appraisal lasted more than one month and ended recently.

Two collisions BYD e6 electric car was damaged and caught fire.

Brief introduction: According to the video and the measured road data, the expert group determined the speed of the GTR red sports car before braking, predicted the collision speed of GTR according to the statistical experience, determined the speed range of e6 according to the video and GPS data, and made repeated simulation calculation and cross-check according to the measured trajectory, the parking position and posture of the vehicle after the collision and the coincidence degree of body damage and deformation.

According to the research results, the speed of GTR is about 183 ~ 195 km/h, and the speed of E6 is about 81~ 83 km/h; The speed of e6 when the tail collides with the trunk is about 64.5 ~ 67 km/h.

In the "5.26" accident, the GTR red accident sports car was traveling at a speed of about 242km/h, but after braking and slowing down, it still had a serious collision with the e6 pure electric taxi traveling in the same direction at a speed of about 8 1km/h, and the relative speed of the two cars exceeded 100km/h during the collision. After the collision, the e6 pure electric taxi slipped out of control to the right and front, and the tail collided with the roadside tree seriously, and the trunk invaded the car body as high as 1050mm, causing damage to the e6 pure electric taxi, three people died and the vehicle caught fire.

Three passengers were fatally injured in two serious collisions.

According to reports, according to the results of field investigation, the expert group conducted a simulation test with dummy model to simulate the situation that e6 driver wore seat belts and two passengers in the back row did not wear seat belts. According to the collision simulation analysis, the injuries of the three passengers are as follows: when the GTR red sports car collided with the e6 electric car for the first time, the HTC (head injury value) of the e6 driver, the rear left passenger and the rear right passenger were 2349.39, 3039.56 and1832.82 respectively; When the e6 electric vehicle collides with a tree on the road for the second time, when the driver HTC of e6 is greater than 1860, the possibility of survival of the injured person is extremely low.

The analysis shows that in two serious collisions, the degree of mechanical damage suffered by three passengers in e6 pure electric taxi seriously exceeded the tolerance limit of human body, causing fatal injuries to three passengers.

Cause of fire: interior materials and some batteries burned due to short circuit.

The expert group specially sends staff to analyze the surveillance video frame by frame (the clock is calibrated). According to the analysis, BYD e6 car started to flash after hitting the tree at 03: 08: 40.20, with about 30 times, and the duration was about 16 seconds. Then there is a small flame on the right side and in the middle. After about 18 seconds, the flame can be seen on the rear roof.

After the arc flashed for 42.45 seconds, Guangdong BG3Y07 electric taxi driver Wu Haiyun ran to the burning BYD E6 car BH 1Q78 with a fire extinguisher. At this time, flames can be seen on the roof and the lower right, accompanied by a large number of smoke rising and drifting north. After an arc flash of 5 1.8 1 sec, driver Wu Haiyun began to put out the fire and the flame turned black. After 55.38 seconds, the flame began to turn red again.

At 3: 29: 07, the first fire truck arrived at the scene of the accident. On May 26th, 20 12, water spraying was started. 20 12 The fire was successfully put out at 3: 33: 58 on May 26th.

Wu Zhixin introduced that according to the fire scene inspection, forensics detection, battery system verification and many verification tests, it was judged that the e6 pure electric taxi suffered two serious collisions, the rear of the car body and the battery tray were severely deformed, and the power battery pack and the high-voltage distribution box were severely squeezed, resulting in some power batteries being damaged and short-circuited, and the high-voltage line in the high-voltage distribution box was short-circuited with the car body, resulting in an arc, which ignited combustible materials such as interior materials and some power batteries.
