At the end of last year, there was a tragic traffic accident in Qingyuan, Guangdong, a new energy SUV model rear-ended a truck, the SUV roof was lifted, and the A B pillar was suspected to be broken. According to the results of the investigation, the speed of this new energy SUV reached 96km h at the time of the collision, although speeding was the main cause of the accident, but everyone is puzzled that the speed of less than 100km h can make the body like this?
The second accident case is related to battery safety, last year there was a pure electric SUV model directly hit the toll booth at high speed, there was no sign of slowing down before the incident, the vehicle deflagrated directly after the collision accident, and the members of the car unfortunately all died. These two accidents can't help but make people think, what kind of new energy vehicle body strength is hard enough? What kind of new energy vehicle battery is safe enough?
Let me talk about another accident case, this accident should be able to reassure everyone, not all electric vehicles can be injured by serious collisions can hurt the lives of passengers in the car. The accident occurred in Jiangxi, a Nezha S driving on the road at night, suddenly two basketball-sized stones appeared in the middle of the road, the driver made an emergency avoidance after the vehicle lost control and crashed into the trees on the side of the road, according to the owner's account, the speed of the vehicle at the time of the accident was about 100km h or more.
We can see that the vehicle directly hit and stopped on the tree during the accident, and we can also see that the front of the vehicle was seriously damaged, but unlike the two cases above, this time the battery of the vehicle in question showed no signs of deflagration, the passenger compartment structure was intact, and the driver was not injured.
In the third accident, Nezha's Tianshu early warning platform was able to receive the early warning in the first time when Nezha S had an accident, and the vehicle's high-voltage system was safely powered off immediately, the current dropped to 0A, and the temperature, voltage and insulation of the battery remained normal. It can be powered off as soon as possible to avoid deflagration after impact to the greatest extent. Nezha S's Tiangong battery has also passed 900+ tests, and the module adopts a lightweight and high-strength aluminum frame design, which can still work normally after vibration, shock, extrusion, and drop tests. The three-layer electrical safety protection mechanism can effectively avoid the risk caused by possible electrical short circuit in the vehicle module in the accident. The battery pack layer adopts a high-strength aluminum alloy frame box, and the integrated design of the body makes it withstand various extreme tests with zero intrusion of the battery cell.
Battery safety is the top priority of new energy vehicles, since it comes to Nezha car, Nezha S also encountered a tragic accident during the Spring Festival this year, the owner of the car was driving on the mountain road in Gansu, the road was covered with snow and poor adhesion, the vehicle rolled down the hill after losing control, and stopped after rolling for at least 6 laps, and the vehicle did not occur, and thanks to the strong body structure, the integrity of the passenger compartment was ensured, and the driver was only frightened and bruised on his hands, Other than that, it's fine. This kind of rolling wrapped in potential energy is a test of the rigidity of the body, Nezha S body steel is solid, the use of high-strength steel accounts for more than 76% of the vehicle, and top hot stamping steel is used in key areas such as A B C pillar and door impact beam. Nezha S is also one of the earliest models in China to adopt an integrated hot-forming door knocker, the front door opening adopts laser tailored welding integrated hot-forming, and a high-strength bolt connection is added between the A-pillar and the hinge column, and the overall rigidity of the passenger compartment is higher. Nezha S adopts a body strategy of three verticals and seven horizontals, and establishes load-bearing rings in 11 key parts such as the top of the body, the B-pillar, the front cabin, and the front baffle, which can ensure the user's living space in the event of an accident.
There are thousands of roads, safety first, no matter how solid the materials of this car are, no matter how good the battery safety of this car is, it is always people who sit in the driver's seat and hold the steering wheel. Do not drive dangerously, do not be strong, do not speed, slow down in advance when cornering, pay attention to rest when driving at high speed, do not drive fatigue, do not drive a vindictive car, and drive cautiously in accordance with the law, which can avoid accidents and ensure safety to the greatest extent. Of course, if you buy a car, buying a car with a high safety factor is also a kind of protection for yourself and your family. Now Nezha S has a preferential policy of 5000 yuan for the whole system, and it has also taken the lead in launching a value-preserving exchange policy, car owners can now enjoy free car orders within 2 years to 7% off the ticket price to buy this brand model, so that consumers have no worries about buying a car. It is worth mentioning that Nezha Automobile has joined hands with 360 Group to promote the large-scale model product Neta GPT on the car, which will be applied to the intelligent cockpit and will be launched in April. At the same time, in the past February, Nezha Automobile completed the delivery of 6,085 units, and broke the situation at home and abroad, accelerating the pace of globalization.
