20,993 USD Galaxy L7 collision score comparable to 62,981 USD LEADING IDEA L9, is it true ability or bragging?

Recently, Galaxy L7 became the first electric hybrid SUV to obtain C-NCAP "five-star certification" with a comprehensive score of 90% in the C-NCAP safety collision test.

This score is the highest among all the SUV participating in the C-NCAP test. in the field of new energy, the overall score is second only to the LEADING IDEA L9 (91.3%) and Zhiji L7 (91.3%), which are sold at the price of 450000. Galaxy L7 achieves ultra-high security comparable to the 450000 new energy SUV with a price of 1/3. How on earth did it do that?

The first five-star certified electric punk SUV

First of all, let's analyze this safety collision test in detail. Galaxy L7 has performed well in fully overlapping frontal collisions, whipping tests, side column collisions, and 50% frontal offset collisions.

For example, in a frontal collision, the Galaxy L7 has a frontal impact of 50 per hour to fix the rigid barrier. From the field results, the energy absorption collapse zone of the Galaxy L7 engine cabin absorbs the energy during the collision very well and basically does not invade the crew cabin. Look carefully, even the two front wheels are not deformed. The key is that there is almost no change in the A-pillar, and the two airbags in the front row pop up immediately after the collision, protecting the front dummies from injury in time.

It is also possible that many people will overlook that the Galaxy L7 has no obvious left and right displacement after the frontal collision, which avoids the secondary injury caused by the deviation in the rear-end collision.

Then there is the offset collision with the highest probability and mortality in traffic accidents. In the experiment, the test car and Galaxy L7 collided with 50% frontal bias at a speed of 50% per hour, which means that the relative speed of the two cars reached 100 per hour. Galaxy L7's performance is still not disappointing.

From the video of the scene, the front anti-collision beam of the whole vehicle collapses and absorbs energy, at the same time, the emergency flasher is turned on normally, and the switch is not affected. After the accident, it also has a good warning effect to the pedestrians or vehicles behind. To a certain extent, it ensures the safety of passengers in the car. The airbag was also opened at the first time, the key is the impact on the main driving position, the Galaxy L7 battery did not catch fire, which has also been verified in the side column collision link.

And then the whipping test. You can simply understand it as a simulated rear-end collision process, by testing the neck injury of the dummy after the collision to evaluate the protective effect of the seat headrest on the neck of the occupants. From the video point of view, the dummy after the "rear-end" after the normal shape, the head and neck did not suffer much impact.

In the end, Galaxy L7 got a high score of 92.71% in the occupant protection project, and 89.58% in active safety, with an overall score of 90%, making it the first electric hybrid SUV to obtain C-NCAP "five-star certification".

Galaxy L7 can have such a result, in fact, it is not surprising, because Geely has put safety in the first place in the early stages of design and development, especially in the more important area of battery safety of SUV. Galaxy L7 has done its homework and is equipped with brand-new Aegis batteries.

Compared with the current mainstream power battery on the market, Geely pioneered the four major standards for battery safety. At the level of battery, PACK and vehicle architecture, Galaxy L7 is built in accordance with the higher requirements and more stringent design and development system than the national standard.

For example, at the most basic cell level, the Aegis battery uses low reactive electrolyte and heat-resistant coating technology to ensure that the core temperature is always kept in a suitable and safe range; the battery package is equipped with a field lattice frame with higher structural strength, leaving a double collapse space between the core and the box, and the bottom uses 1.5mm 1180DP high-strength steel plate, which is more than twice the tensile strength of ordinary steel plate.

Of course, for users, it makes no sense to put aside the whole vehicle and talk about battery safety. Only when the car body structure also meets ultra-high safety standards can consumers rest assured.

To this end, Galaxy L7, based on Geely e-CMA intelligent superelectric architecture, provides the same class of leading aviation aluminum alloy anti-collision beam, as well as the same class's unique integrated thermoformed boron steel door ring, the torsional stiffness and compressive strength of the vehicle have been greatly improved.

In the most critical chassis structure, the Galaxy L7 chassis uses a 1.8mm thick double-layer steel plate frame structure, the first four vertical and four horizontal floor structure, around the Aegis battery safety system to form a comprehensive super-rigid strength protection, when subjected to external extrusion or collision force, the longitudinal beam and crossbeam can effectively disperse more external impact to ensure that the internal battery will not be hit.

On this basis, Galaxy L7 does not blindly seek "hard" and "hit hard" in the process of collision, but uses a patent for clover collapse structure, through two unloading paths and W-shaped double bending technology, somewhat similar to Tai Chi's "borrow force", perfect removal of collision energy and reduce the impact on the body structure and battery pack.

In addition to battery packs and vehicle safety, Aegis batteries have also set new standards for intelligent safety. The BMS 3.0battery management system can realize all-weather monitoring of the battery by combining AI algorithm. Through the battery hazard isolation technology, the high voltage power outage of the whole vehicle can be realized within 0.065 seconds after the collision, and the risk of high voltage leakage and fire can be avoided.

After making full preparations, on the eve of the launch of the Galaxy L7, Geely also conducted a series of "devil tests" for the Aegis battery to verify its safety. First, four basic battery safety tests, including the acupuncture test, made the Galaxy L7 pass smoothly; it is close to carrying out the industry's first high-speed bottom collision test of the new energy vehicle for the whole vehicle, and almost every test is carried out above the industry standard.

For example, in the "full vehicle forward scraping" test, the Galaxy L7 needs to drive to a solid steel hemisphere with a diameter of 150mm and vertically overlapped with the battery pack 30mm. The test speed reaches 40km/h, which is 10km/h higher than the industry standard, and the collision energy between the solid hemisphere and the battery pack is 1.78 times that of the industry label.

This is like we study according to the standard of Mathematical Olympiad in the daily test, facing the final test at the end of the year, the normal test paper is easy to catch, so it is not difficult to understand why Galaxy L7 can get a high score in the C-NCAP safe collision.

Summary

< span > A few years ago, when new energy vehicles were just emerging and plug-in hybrid SUV began to be popular, people focused on how low fuel consumption and how fast the car ran. Now, when more and more domestic hybrid SUV performance and energy consumption stand on the same level, safety has become the focus of consumers' choice and purchase of hybrid SUV. < / span >

As the first electric mixer SUV through C-NCAP "five-star certification", Galaxy L7 put safety in the first place from the beginning of research and development and design, and built a comprehensive body safety system from many areas of body structure, battery safety and intelligent security, bringing users the safety performance of luxury new energy SUV and solving users' consumption pain points. For those consumers who are concerned about car safety, with the authoritative endorsement of C-NCAP, Galaxy L7 is undoubtedly more worthy of rest assured.
