Recently, Extreme Krypton joined the China Automotive Industry Center’s TOP Safety Challenge Platform to successfully complete the Extreme Krypton 009 "Double A-pillar" challenge to the dynamic top pressure of a 30-ton concrete mixer truck, and received an authoritative report from CCTV News on the National Traffic Safety Day on December 2, once again defending the "safest in the world" industry reputation.
This challenge restores the rollover situation that often occurs in real life: at the intersection, a large concrete mixer truck with a total weight of 30 tons turned right on the unilateral bridge at a speed of 20 kilometers per hour, and rolled to the left to form a collision and rolling on the roof of the main driver of the polar krypton 009. "Double A-pillars" bear the brunt.
The test results show that after being subjected to the overload impact of the mixer tank, the front windshield of the JK 009 car only cracked at the angle, the body structure was intact, and the ABC column of the vehicle did not show obvious bending, depression or rupture. The doors and taildoors on both sides of the car can be switched on and off normally, the chassis air spring rebounds normally, the erosion of the passenger compartment is not obvious, and the head, neck, spine, chest, hips and legs of the dummy in the car are all excellent. The vehicle can run normally, and the three electricity safety is all normal.

Hard and rigid "top pressure killer" exceeds the national standard by 11 times the top pressure strength
As we all know, large trucks and concrete mixers are prone to rollover on the roof of passenger cars due to their high quality and high center of gravity, becoming a veritable "top pressure killer", and top pressure is often a weak link in the safety design of many models.
Extreme Krypton 009, as the world’s first native pure electric luxury, completely subverts the traditional safety defects. The maximum pressure resistance is 128kN, and the roof can bear up to 13 tons. In order to verify the safety performance of Extreme Krypton 009, this test changed the static pressure working condition of the national standard to the dynamic working condition, and the difficulty was greatly improved. To further improve the difficulty, the 30-ton concrete mixer truck completed the rollover through the unilateral bridge climbing, with a higher center of gravity than flat ground driving and greater collision energy. In the comparison test before the test, an elderly scooter instantly became a "waste" under the rolling pressure of the mixer truck.

"Double A-pillar" hardcore absorbs energy and creates a safety fortress
Extreme Krypton’s outstanding safety performance is no accident. Unlike most that only use a single A-pillar, Extreme Krypton 009, known as "Highway Tankrypton", introduced a hidden double A-pillar into the model, setting an industry precedent.
The A-pillar of Extreme Krypton 009 uses 2000MPa ultra-high strength thermoformed steel, the yield strength is 2 times that of nuclear submarine steel and 8 times that of ordinary process, and the CBS composite filling technology is used in the A-pillar. The stable triangular design, four-layer reinforced structure and the load-bearing point is moved back 480mm, so that Extreme Krypton 009 has a wider buffer energy absorption area, which can effectively absorb the frontal and longitudinal impact force of the A-pillar, reducing the damage to the front row passengers. Being able to "withstand" the heavy pressure is not only the safety confidence cast by Extreme Krypton’s "double A-pillar", but also the strength of the hard core to protect the safety of passengers.

This dynamic top pressure challenge was broadcast live throughout the process. In the second scene, Professor Zhang Jinhuai, director of the Automotive Crash Test Room of the State Key Laboratory of Automotive Safety and Energy Conservation of Tsinghua University, and Yang Heping, a senior safety expert at Extreme Krypton, jointly witnessed the real top pressure safety test results of Extreme Krypton 009.
"The scientific design method of the triangular double A-pillar has played an important role in this dynamic top pressure test", "In terms of design, materials, craftsmanship, etc., the body of the extreme krypton 009 is the best, and it is well deserved!", Professor Zhang Jin gave a high evaluation of the safety ability of the extreme krypton 009 at the scene. "In addition to ensuring the safety of passengers, the safety of the three electricity is equally important. During the collision process, not only must the passengers be protected in all aspects, but also the normal operation of the three electricity needs to be ensured," added Yang Heping, a senior safety expert at the extreme krypton.

Extreme safety gene, all-round care for user safety, in this live broadcast challenge, Extreme Krypton once again led the industry’s testing standards, using the most demanding crash test to build a well-deserved "safety fortress".
The safest in the world, once again verifying the national reputation of "Highway Tankrypton"
All along, the safety performance of JK 009 has been tested by "actual combat" for a long time. For example, JK 009 has rear-ended a semi-trailer, but the A-pillar did not bend, instead tearing a hole in the thick steel plate of the semi-trailer’s tail. Coincidentally, JK 009 was rear-ended by a double-decker bus and then hit the front. Only the front cabin was deformed and the rear window glass was broken, and the frame structure remained highly intact. At the same time, the vehicle can even maintain normal driving, indicating that the three electric and transmission systems have not been damaged.

"Don’t be afraid of collision, don’t catch fire", excellent safety genes, derived from the 720 ° all-round safety armor protection of "Extreme Krypton Safety". In addition to the hard core "double A pillar", in terms of battery safety protection, Extreme Krypton 009 pioneered the "ten grids" battery anti-collision structure, using the industry’s thickest aluminum side anti-collision beam, which buffers the battery layer by layer when it is hit. Relying on NTP non-thermal spread and no fire technology, it can effectively prevent battery combustion. Extreme Krypton products have been delivered to more than 180,000 vehicles, and it still maintains the "world’s only zero spontaneous combustion" record. This is the best proof of Extreme Krypton safety.

In the traditional weakest rear of the car, JK009 has also successfully created an integrated die-cast rear-end aluminum body through the industry’s largest 7200-ton giant die-casting machine, reducing the welding point by nearly 800, reducing the deformation by 16% in the event of impact, increasing the bending stiffness by 11%, and increasing the torsional stiffness by 9.5%. The vehicle stiffness is more than three times that of traditional luxury, effectively protecting the rear safety. Not only that, but the integrated die-cast rear-end aluminum body has also set up a two-stage removable buffer structure through an innovative four-stage collision partition strategy, which can greatly reduce the maintenance cost of the vehicle after a collision.

Hardcore guards safety, strength is not afraid of pressure! In the face of various difficult tests, Extreme Krypton 009 writes safety into its genes, not only achieving all-round protection of 720-degree safety armor, but also establishing internal standards in safety conditions that are not met by global standards such as front center pillar collision and 15 azimuth side collision tests. It can not only answer additional questions, but also achieve "autonomous life scroll".
Defining "Highway Krypton" with "Extreme Krypton Safety" not only brings users "all six seats are safe", but also raises the pure electric luxury safety standard to a new height!
