New force electric vehicle is not reliable? It is not yet!

Although the electric vehicle is not a fresh product, it is a high-risk battery that provides power by highly flammable batteries and high-voltage electrical systems, many consumers are very concerned about their security or speech.

With the negative news of various electric vehicles that have been exploding at home and abroad in the past two years, don’t say that the electric vehicles of traditional cars have been shaken many car purchase. Confidence, the new forces brand electric vehicles do not have enough product experience before the prior to, it seems to be more difficult to obtain the safety trust of consumers.

However, do the electric vehicles made by the new forges are certainly unsafe? It doesn’t think so.

In fact, it has successfully removed our inherent prejudice of new forces electric vehicles with a “Safety Day” of “Safety Day”.

The new forces electric vehicles are not provided with good safety protection performance, at least 蔚 来, and its actual performance is even better than some traditional luxury brands.

Clear security concept as the user experience

Before visiting experience, the engineers of the military first told their understanding of the safety concept of electric vehicles.

In the view, the so-called security is two-story, one is “safe” of electric cars, One is to let the user “peace of mind”. If you want to do this, you should reduce the rate of injury from the reduction rate.

First, before the accident, avoid / reduce the probability of accidents, and reduce the severity of the accident; when an accident occurs, the degree of injury to the human, car, and third parties; After the accident, it is necessary to reduce the waiting time of the user, improve the prolonged extension.Continued to ensure.

In these three accidents, it is equipped with a corresponding and rich main passive safety protection device and measures for electric vehicles, which are based on the forward direction. R & D system is designed and manufactured.

In the case of a smart security assistant including fatigue driving monitoring, emergency brake assistance, forward collision warning, etc. system.

The accident is 17 safety protection devices, including all aluminum body, airbags, safe gas curtains, high pressure loop gunpowder emergency cuts.

After the accident, there are 8 security measures such as multi-collision brake system, door handle bomb, high-voltage battery condition monitoring HV. It can be seen that it is quite comprehensive for safety protection for the entire electric vehicle.

Direction to R & D system and advanced test experiment

[ 123]

To create a high-performance, high-security product with independent intellectual property rights, it is necessary to build a positive research and development system, and must be carried out in the previous period of vehicle development. More stringent experimental tests.

And each new car, every new car, must experience multiple tests from virtual testing to real-heart test, from components to system integration. Collectively accumulate a lot of data, and ultimately it can present a high quality electric car.

To this end, the two test centers have been established, introducing advanced test experimental equipment in the world, and independent core trials are independent, and establishing openings. testing platform.

Among them, the first test center is mainly surrounded by electric drive, battery, electric control, electricThe technical hardware and software development and test test of force assembly are launched.

The second test center we visited is started in August 2016, which is a wider range of hardware and software coverage. Laboratory.

The test center contains 24 laboratory and works, covering vehicle, vehicle electronic architecture, three electricity, electronics, intelligent car software, automatic driving, power management and charging Significant Electric Vehicle All-Based Test and R & D Service for Exchange Facilities, After-sales Service, Spare Parts Management and Distribution.

In the second experiment center, several core experiments and test highlights of electric vehicles have an important role, and it is simple to introduce you.

Not just “five-star safety” collision score

[123

How is the security of an electric vehicle, in addition to the large number of development inputs in the previous period, can display the most intuitive results of consumers, which are their various The collision test has been achieved.

The Second Experiment Center showed three EC6 models participating in the Chinese to protect C-IASI, allowing you to review its collision performance.

蔚 来 EC6 gets all G (excellent) achievements in the vehicle occupant safety index, the outer pedestrian safety index, the vehicle auxiliary security index project, which is 25% of the front. The collision and side collisions have obtained the full score of zero defects. A (good) achievement is obtained on the most difficult cue and maintenance economy index of luxury cars.

Can achieve such excellent results, naturally inseparable from the strict consideration of safety performance. Specifically, for example, a front 25 percent bias collision test, the vehicle structure and constraint system when the vehicle is collided with the front side of the vehicle in 64km / h Protection of occupants in the car.

The awareness of security strategy is that the collision power on the side will avoid the front anti-collision beam, pass it up to the upper beam, then pass the A column, the door DisperseHit.

Next, pass through the hub to the Torque Box protection hub and the threshold, and then transmit the collision force to the A column, TOE BOARD and Sled panels, thereby dispersing the force to the rear of the vehicle and the non-collision side, thereby ensuring the non-deformation of the passenger compartment and battery bin.

This Torque Box is a key part of the EC6 white car. It uses three-dimensional formation, and the three-dimensional multi-dimensional support provided by the damwheral dams, the entire component is manufactured by high pressure aluminum casting process. It has powerful impact resistance.

As can be seen in the 25% bias collision, the front airbags and side air curtains standarded normally popped up in the EC6, and the side air curtain is covered with full range. Under the blend of double-pre-tightening seat belts and the combination of the crushing pillars, the occupants of the vehicle have been protected in the vehicle.

After another collision, you can see that the door can be opened normally. The structural integrity of the whole vehicle is quite excellent, and the internal passenger cabin is much smaller than the limits, the foot and the legs are not visible to intrusion.

It can be said that it is a safe passenger cabin to create a rugged body structure.

The lower side collision test is said to investigate the protection of passengers in the car when the vehicle is hit by SUV or pick-up side impact.

When the collision occurs, the threshold beam, the door, and the B column becomes the most important power point, at which point the collision impact force passes through the plurality of strengthening the beam and transmits.

The reinforcing beam of the EC6 chassis is greatly role here.

The beam is a 6-series aluminum material, by extrusion and stampingThe process is manufactured, and excellent guarantees the safety of the occupant and the battery under the side touch, and the front and rear protective hubs can also serve as a side support, and maintain the vehicle safety together in the miles of the miles.

After the side touch, it can be seen that the EC6 side air curtain is normal, and the body intrusion is extremely small, and the strong body material and structure ensure that the occupant is very large enough, and The battery mechanism is not deformed by the impact of the collision.

Further, based on the electric vehicle developed by the pure electric platform, the bottom of the battery is lower, the center of gravity is lower, and the risk of risking after the collision can reduce the damage caused by the second accident.

At the same time, EC6’s main chipping standard with laminated glass, there is no glass splash when there is an accident, and it also prevents secondary injury to the user.

Finally, the roof intensity test, this test is investigated that the vehicle body structure resists deformation when the vehicle is rolling, thereby evaluating the protection of the vehicle to the occupant.

The results of the test show that the EC6 equipped with a 2.1 square meter glass roof, the top of which can withstand 103KN forces in the 127mm deformation, which is more than 10 tons. The performance is extremely excellent (when the ratio of peak loads and vehicle weight is greater than or equal to 4, it is excellent).

This is because EC6 has a strengthening design for key parts such as B columns, upper A columns, and front-top beams, and high-strength aluminum alloy materials.

Combined with advanced connection processes, such as SPR, FDS, laser welding, structural glue, etc., such that EC6 can resist more than 10 tons of external forces in a smaller deformation. If the vehicle is rolling, the body structure provides adequate security to passengers.

Of course, in addition to the excellent body structure, it is also designed a complete high-voltage electricity safety strategy for electric vehicles.

Including the high-voltage electrical module to protect the high voltage electrical module from the impact through the high-strength frame structure; in the collision, high-voltage electricity can be cut in 0.011 seconds; 2.4 seconds after collision, radical capacitance internal electricity, high-pressure parts, occupants and car outside the car, high voltage loop Fully insulated; other multiple mechanisms of power-down and discharging of high-voltage electricity when collision are guaranteed from hardware and software.

In fact, it is necessary to achieve such good results in the C-IASI collision, because of its reference stage, it is the safety collision criteria and norms of Europe and America. Come to prepare for advance in the European and American markets.

Therefore, it is also an increase in the requirements of C-IASI and China’s regulations, but also increased the side column touch, and the FMVSS 301 is rearranged. Waiting for classic test content, I believe more market inspections, but also make the security of the awareness more comprehensive.

This time, it has been dismissed with the safety prejudice of some of the new forces electric vehicles.

In fact, new forces that spend a lot of effort and financial resources and putting down the new forgers of the car have used action to prove that their electric vehicles can be safe, they can be very assured .

Of course, we sincerely hope that the electric vehicle can get out of the country as soon as possible, let more global consumers feel the excellent performance of China’s brand electric vehicles.
