In the era of fuel vehicles, the development cycle of a New Car is 5~7 years on average. And the era of new energy vehicles, new brands and new models of new crazy volume, this cycle is constantly being shortened to the current 9 ~ 12 months. R & D cycle limit compression, the safety of automotive features have been fully verified? Raise consumer questions. With price wars and wars of words raging, in the increasingly frenetic automotive market, which brand can still calmly verify the safety of their vehicles? The ID.7 VIZZION, which is about to go on sale, has not only been fully verified, but has even achieved "redundancy".
Far beyond the national standard, safer than safe battery
Battery safety is the most critical safety for new energy vehicles.Currently, new energy vehicles on the market advertise that their batteries have gone through a number of validations and provide top-level safety protection, but the repeated occurrence of battery fires in the press shows that there is still a long way to go in terms of battery safety.FAW-Volkswagen has taken the lead in disclosing the Changchun laboratory of its new technology research and development centre, which shows its confidence in creating the ID.7 VIZZION's "redundant safety".FAW-Volkswagen pays special attention to the battery safety issue that consumers are very concerned about. Referring to Volkswagen's high-grade safety standards in Germany, FAW-Volkswagen conducts safety tests on batteries that far exceed the national standard, such as 197 tests on overcharging prevention, short circuit, etc. While the national standard only has 18 tests, FAW-Volkswagen's tests far exceed the national standard by 179 tests, and it also conducts a total of 436 full-scale tests on battery packs and battery batteries at the level of the battery core and the module.A total of 436 full-scenario tests are conducted from the cell level to the module level to the battery pack level to protect battery safety in all aspects.
Vibration and immersion in water are the most testing scenarios for batteries in daily use, and FAW-Volkswagen's battery safety test requires harsh requirements for these two scenarios. The national standard requires that the battery should not catch fire for 13 hours under the vibration condition of 3 degrees of freedom, while FAW-Volkswagen's test has tripled the vibration level and can reach 172 hours without fire. The requirement of the national standard for the water immersion test is that the battery will not catch fire and explode after being immersed in water at room temperature for half an hour at a depth of 1 metre, while FAW-Volkswagen has added the water immersion temperature impact test on the basis of the test, in which the battery pack is heated up to a high temperature of nearly 60 degrees Celsius, then immediately immersed into ice water of a few degrees Celsius and circulated for 20 times, so as to verify the rationality of the design of the structure of the battery pack and the stability of its craftsmanship by means of the ultimate thermal expansion and contraction and the effect of negative pressure, and to let even the slightest fluctuation of the welding process be verified. Even the slightest fluctuation in the welding process is verified and optimised. The passing standard of the test is to confirm that there is no change in the performance of the battery after comprehensive function and performance parameter testing and dismantling.
In addition, FAW-Volkswagen completed the test without missing a single item, such as high-temperature and high-pressure water jetting and long sequence test, which are not explicitly required by the national standard. It is understood that many car companies do not do tests that are not rigidly required in the national standard, but FAW-Volkswagen has fully verified all of them in the testing room, which shows ID.7 VIZZION's dedication to safety and quality.
Body stiffness is stronger than a million-dollar luxury car.
In the era of new energy vehicles, the value of new cars is getting higher and higher, and the cooler the configuration and the more fancy the features, the more it can attract consumers' attention. Under the environment of cost compression, some car companies have to spend their limited budgets on those flashy functions in order to meet the consumers' demand for "face", and pay less attention to safety accordingly. However, FAW-Volkswagen has not given up the pursuit of higher safety standards, and has made ID.7 VIZZION a car with a face. In addition to battery safety, the safety performance of a new energy vehicle also depends on the frame structure, active and passive safety devices. Firstly, in terms of body materials, ID.7 VIZZION adopts a high-strength steel-aluminium hybrid body, of which more than 32% is hot-formed steel, more than 81% is high-strength and ultra-high-strength steel, and aluminium alloys are used in the longitudinal beam reinforcement, four doors and the rear cover, with the torsional stiffness exceeding a staggering 46,100Nm/degree, which is even stronger than many multi-million-dollar-class luxury cars. Secondly, in terms of body structure, ID.7 VIZZION starts from a high point and is designed and developed in strict accordance with the latest C-NCAP 2021 five-star and C-IASI Good standards, with two seat reinforcement beams running through the left and right at the bottom, and the use of 2000MPa aircraft carrier-grade strength thermoforming materials, effectively resisting side impacts and protecting the body. The two seat reinforcement beams at the bottom, which run through the left and right sides, are made of 2000MPa aircraft carrier strength thermoforming material, which can effectively resist side impacts, protect the body and ensure that the battery module is not deformed in the collision. It is worth mentioning that Volkswagen engineers, after thousands of simulations, tests and optimizations, have developed a "sandwich" structure of inner and outer double-layer thermoformed steel and honeycomb aluminium reinforcing beams in the threshold of the ID.7 VIZZION, with a honeycomb aluminium cross-section of more than 150mm in width, and the irregular honeycomb chamber collapses step by step from the outside to the inside when side impact occurs. When a side collision occurs, the irregular honeycomb compartment collapses step by step from the outside to the inside, coupled with the double-layer high-strength thermoformed steel inside and outside, which protects the body while also forming a 4-fold collision protection for the battery pack (outer door sill -> honeycomb aluminium impact beams -> inner door sill -> battery pack reinforcing frame), and the overall collapsed space is up to 250mm, which is capable of carrying an impact of more than 120 tonnes, which is far more than that of the same class of products by a factor of several and brings the most extreme safety protection to the batteries and members of the vehicle. The ultimate safety protection for the battery and the members of the car.
Endorsement of "Redundant Safety" in All Dimensions
Behind the safety quality of ID.7 VIZZION is FAW-Volkswagen's excellent global R&D and manufacturing strength and costless investment in technical innovation and body materials. Taking the electromagnetic laboratory that guarantees the information security of intelligent vehicles as an example, FAW-Volkswagen's electromagnetic laboratory covers an area of 3,000 square metres, and has a number of electromagnetic compatibility laboratories that satisfy corporate standards and national standards, such as a 10-metre darkroom, a 3-metre darkroom, a static room and a shielding room, so as to provide all-around protection for the radiation and immunity of the entire vehicle's electrical parts. At present, the laboratory has passed the domestic standard CNAS certification and the German Volkswagen EXP/P certification, which is higher than the industry standard. In the absence of this kind of laboratory in many enterprises, FAW-Volkswagen is more stable and farther away than many of its counterparts. Safety is more important than Mount Tai, and the safety of new energy intelligent vehicles is even more multi-dimensional. ID.7 VIZZION has made all-round considerations in various scenarios of driving the vehicle, taking the safety of human life as the bottom line, and effectively responding to the situation of driver incapacitation, parking safety, and driving safety.In the event of a driver's sudden illness, the Emergency Assist 3.0 system in ID.7 VIZZION detects that the driver has not taken over the steering wheel for a long period of time, and reminds the user to take over the driving by means of audible and visual warnings, tightening of seat belts, and braking to shrug off the car.If the driver still does not take over driving, the system will automatically stop the car and automatically activate the electronic handbrake EPB; after stopping the system will automatically sound the horn, activate the interior lighting, reduce the volume of the entertainment system, disengage the door locks, and through the eCall emergency call to guard the safety of the car, in order to reduce the risk of accidents. As for the safety of the interior environment, which is of great concern to many users, ID.7 VIZZION is developed in accordance with the five-star standard of the C-AHI China Automotive Health Index of the China Automotive Centre. Through the use of top-quality environmentally friendly materials, real-time air monitoring, double-layer filter elements, equipped with an anion generator and other scientific and technological innovations, the formaldehyde content of the interior complies with the safety standards for mothers and babies and reaches one-tenth of the international standard value, as well as theone-fourth of the most stringent Finnish indoor S1 limit value standard, guaranteeing the safety of the car's interior environment. It can be said that ID.7 VIZZION's "redundant safety" realises a full range of safety transcendence, including body safety, three electric safety, driving safety, environmental safety, information security, etc., with a higher standard than the industry standard and international standard, bringing users the most solid sense of security with the greatest sincerity, and eliminating their doubts and concerns about electric intelligent vehicles. The company will bring users the most solid sense of safety with the greatest sincerity, eliminating users' doubts about electric smart cars, giving new energy vehicles a rightful name, and advocating for "redundant safety".
