Without fear of ＂wind, rain and lightning＂ and ＂fire＂, look at the hard core quality of Hongqi EH7

When buying a new energy vehicle, what is the most important thing? Battery life? Intelligent? Configuration? These are of course very important, but what is more important is safety and quality.

With the technological development of new energy vehicles, both battery life and energy efficiency have been greatly improved. Therefore, today’s battery life anxiety is no longer the biggest anxiety of electric vehicle users, but the biggest anxiety is "safety anxiety".

According to the latest data released by the emergency management department, the spontaneous combustion rate of new energy vehicles rose by 32% in the first quarter of last year alone, and an average of 8 new energy vehicles caught fire (including spontaneous combustion) every day. It can be seen that since the popularization of new energy, there have been endless news about spontaneous combustion and other safety accidents. Because of this, consumers will be more concerned about the safety of new energy vehicles.

So, in the face of users’ safety anxiety about new energy vehicles, how should car companies solve the problem? As a "national team player", Hongqi’s approach can be described as "simple and crude" and highly credible. That is, through various extreme challenges, the safety performance of new energy vehicles in extreme environments has been fully verified.

Without fear of "wind, rain, thunder and lightning" and "fire", Hongqi EH7 sets a safety standard

In order to allay users’ anxiety about the safety and quality of new energy cars, as the first pure electric car based on the FMEs super architecture of the Hongqi brand, the Hongqi EH7 has successfully passed the "wind and rain" power-free limit challenge.

In this challenge, in order to verify the safety of the self-developed battery pack carried by Hongqi EH7 in extreme weather environments, a test was specially designed to continuously challenge the temperature shock, water immersion and fire of the same battery pack in Hongqi.

The first is the temperature shock test, which is mainly to test the ability of the power battery to withstand rapid changes in ambient temperature. In a confined space, the temperature needs to complete the extreme change from -40 ° C to 60 ° C within 30 minutes, and then maintain it for nearly 8 hours. And this process has to be repeated five times.

In this harsh environment that did not exist on earth, almost all equipment would be damaged, but the battery pack of Hongqi EH7 "survived" unharmed, and the battery pack did not leak, break, catch fire, or explode.

After experiencing high temperatures and severe cold, the battery pack of the Hongqi EH7 was immersed in deep water for another 60 hours.

The current waterproof standard of the power battery is mainly IP67 (the power battery can be placed in 1 meter deep water for 30 minutes without being affected), while the water immersion test of the Hongqi EH7 is to directly immerse the battery pack into a 1 meter deep pool and continue to soak 120 times the national standard time – 60 hours. After the test, it was found that there was no water stain inside the box, indicating that the battery pack was airtight and well insulated. The strength of the Hongqi EH7 battery pack proved that it reached the highest waterproof level IPX8 in the current waterproof experiment.

After going through three limit tests of temperature change, water immersion, and fire, Hongqi EH7 still did not have any safety problems. However, do you think this is the end? Next, Hongqi EH7 went through four tests of sand and gravel, wading, lightning strike, and electromagnetism.

Sand and gravel road, Hongqi EH7 cycled 20km at an average speed of 50km/h, the battery pack was not damaged, the insulation resistance test was normal, and the vehicle was still running normally. In the wading scene in simulated rainstorm weather, Hongqi EH7 traveled 600m back and forth in a wading pool with a water depth of 400mm (4 times the national standard), and the vehicle passed perfectly.

In the electromagnetic test process, in a magnetic field with a frequency band of 10Hz-400kHz, the electromagnetic radiation level of Hongqi EH7 under uniform speed, acceleration and other operating conditions is tested, and the margin is greater than 28dB (the larger the margin, the less harmful the vehicle radiation), which is at the leading level in the industry.

The most striking thing is that the Hongqi EH7 also carried out a lightning strike test. After undergoing the triple lightning strike test of applying a pulsed electric field, generating a discharge effect and a continuous discharge effect, the vehicle did not appear abnormal and could still drive normally. The Hongqi EH7 is also the first pure electric vehicle in China to publicly challenge the lightning strike test and successfully pass.

Overall, the power battery of the Hongqi EH7 can resist freezing, overheating, water ingress, spontaneous combustion, and bumps. At the same time, the safety performance of the entire vehicle in extreme scenarios is also very excellent, which intuitively eliminates users’ concerns about battery safety.

How did Hongqi EH7’s "Incorruptible Body of King Kong" come into being?

Lu Xun once said: "A true warrior dares to face a bleak life!" And a truly safe battery should face a cruel trial.

It can be seen that the test of Hongqi EH7 is very rigorous. The previous three tests: temperature change, water immersion, and fire are all completed by the same battery, which is a great test for the battery.

It should be known that lithium batteries are extremely "sensitive" to temperature. Overheating may lead to combustion or even explosion, and overcooling may cause internal lithium dendrites to grow, pierce the film and cause short circuits and other risks. The Hongqi EH7 battery pack can complete these extreme challenges, mainly because the Hongqi EH7 battery pack adopts the six-sided three-dimensional insulation protection scheme developed by Hongqi, which creates a six-sided three-dimensional insulation protection space for the battery, realizes multi-scene non-thermal diffusion, the highest-level IPX8 waterproof, fire protection and other functions, ensuring that the battery can be used safely and normally in the face of various extreme environments.

However, only excellent batteries are not enough, Hongqi EH7 vehicle passive safety is also very good, using 9H4M cage structure to strengthen body safety, high-strength steel consumption is 74%, of which ultra-high-strength hot forming boron steel consumption reached 22%, easily meet the C-NCAP and E-NCAP double five-star safety rating standards, to prevent vehicle collisions or rollover extrusion of the battery, to ensure the integrity of the battery, for safety up the ante.

More importantly, these extremely rigorous test projects are not designed to fill up the "program effect" and show off the strength of the gimmick, but to truly face the pain points of users in new energy vehicles, and solve the multiple concerns of users on vehicle safety through continuous investment and deep digging in technological innovation. This is what all new energy vehicle companies should follow and learn.

"Zero Pressure, Enjoy Peace of Mind", Open the Era of Green Travel "Zero Pressure"

The "zero voltage" travel of Hongqi EH7 is not only reflected in the safety and quality of the vehicle, but also provides users with "zero voltage" car purchase and use value.

In the context of the current industry-wide price war, Hongqi EH7 did not follow up blindly, but extended its focus from a single purchase link to the user value of the product’s entire life cycle. Launched the "Zero Voltage · Peace of Mind" plan, including the three sub-plans of "Zero Voltage Four Lifetime" service, "Zero Voltage Worry-Free GO" rights and interests, and "Zero Voltage Limited Time Jump" product upgrade. Among them, the "Zero Voltage Four Lifetime" service adds "Lifetime Free Maintenance" to the original three after-sales rights of Hongqi brand: "Lifetime Free Warranty", "Lifetime Free Rescue", and "Lifetime Free Car Pickup and Delivery", which further alleviates the worries of new energy users.

If calculated in cash value, Hongqi EH7’s "Zero Pressure · Peace of Mind" plan allows users to enjoy up to 100,000 yuan. This unique "pet powder" method not only allows users to obtain real benefits, but also enhances the use experience of the whole life cycle of the product. More importantly, it is a demonstration of returning to correct values for the whole industry.

It can be seen that in the face of the crazy price of the industry, Hongqi EH7 does not blindly follow up the volume price, but the volume value. One is the safety value. Hongqi EH7 improves the safety factor of the battery and the whole vehicle in multiple dimensions through the pioneering and cutting-edge safety technology, and brings users the safety quality of "zero voltage". The second is the product value of the volume. The longest battery life is 820km, zero hundred acceleration for 3.5 seconds, 5 millimeter wave radars, all-aluminum chassis, and the maximum speed of the motor is as high as 22500r/min…. Hongqi EH7 has reached the flagship level of the same level in terms of performance and intelligence. More importantly, while having excellent product strength, Hongqi EH7 provides users with the rights and interests of value 100,000.

This kind of volume method not only allows users to have a high "sense of gain", but also does not harm the interests of the enterprise, allowing the enterprise to achieve healthy development, which can be described as brilliant!
