Behind every rock-solid battery, there is a hardcore safety "goalkeeper". With the continuous development and progress of battery technology, tests such as battery scraping through the chassis and underwater immersion are no longer the last hurdles to stick to the "dragon gate", but are only regarded as the "relegation competition" in the battery safety testing industry. Therefore, winning the "Golden Glove Award" in the battery safety testing industry has become the target of various car companies.
On July 20, Fengxing Thunder successfully completed the first public challenge in China - TOP Grade Fengxing Thunder Armor Battery "Driving the Fire Road" safety test, becoming the most powerful contender for the "Golden Glove Award" in the battery safety testing industry. After the triple test of low temperature, high-pressure flushing and thousand-degree fire passing test, Fengxing Thunder finally won the honorary certification of "Extreme Electric Safety Star" issued by the China Automotive Center, verifying its ultra-safety strength with a more intuitive and powerful detection method, and consolidating its leading position as a "130,000-level pure electric SUV popularizer", creating a safer and more reliable travel experience for consumers.
The first time to cross the "fire disaster", the wind and thunder show the battery safety defense "showmanship"
How can you prove that your battery pack is safe and reliable? Wind and Thunder climb to the pinnacle of safety defense "dazzling skills" to give the answer. In order to test the heat resistance of the battery in a high-temperature environment, the Fengxing Thunder equipped with the armored battery successfully traveled for 140 seconds in a 200-meter-long flame road with an average speed of 4km/h, and the temperature of the vehicle chassis contact panel was as high as 900 °C. The results showed that the Fengxing Thunder did not show thermal runaway phenomenon, and the vehicle was in good condition and the driving function was normal. Compared with the 70 seconds of direct combustion of battery packs stipulated in the national standard, Fengxing Thunder uses the safety test of 140 seconds of vehicle-level combustion to push the development of the industry's battery safety test standard system to a new height and contribute new reference value to the inspection of battery safety technology.
Super frost resistant, super waterproof, Fengxing Thunder shows the armor-level defensive strength
In order to further demonstrate the defensive strength of battery safety, Fengxing Thunder Armor Battery also conducts double tests of low temperature and high pressure flushing. In the low temperature test, the staff simulated the temperature conditions in the cold winter in the north, the armor battery was placed in a low temperature environment of minus 40 °C, and after 8 hours, the tester directly transferred the armor battery to a professional high-pressure flushing test room, and used a high-pressure water gun with 80 °C water temperature and 8000-10000kpa to continuously spray the armor battery in all directions. After two consecutive test results, the battery compartment of the armor battery has never seen water seepage, and the battery pack has no short circuit, no fire, no explosion. When the armor battery is reinstalled back into the body, Fengxing Thunder can still start normally and drive normally. It is worth mentioning that the water pressure intensity of this challenge is equivalent to 54 adults stepping on the armor battery at the same time, which shows the strength.
This means that in the face of the environment of freezing in winter and heavy rain in summer, Fengxing Thunder armor battery successfully passed the test, proving its excellent "anti-freezing" and "waterproof" dual strength, and also allowing car owners in the north and south to travel without worrying about battery safety, further strengthening Fengxing Thunder's pure electric hard power of "common to the north and south, regional popularization".
Safety from the inside out, the Wind Thunder Armor battery is indestructible
There is a problem in the development of battery technology, that is, high energy efficiency and high safety cannot be combined. Fengxing Thunder breaks through technical barriers and achieves a perfect balance between the two. The successful passage of the three major safety tests by Fengxing Thunder is inseparable from the support of "four-dimensional ultra-high protective shield technology". This technology comprehensively protects the cell layer, module layer, whole cladding layer and vehicle chassis of the armored battery, so that the battery has the characteristics of high temperature resistance, extrusion resistance, waterproofing and so on. Fengxing Thunder Armor Battery builds a safety protection system like a golden bell hood, which better protects the user's travel safety.
As for the endurance problem that users are concerned about, Fengxing Thunder provides mileage guarantee for ultra-long endurance in the same class. Among them, the "armor battery" uses medium nickel cathode material, the maximum capacity of the whole package can reach 85.9kWh, the energy density is greater than 175Wh/kg, and the CLTC has a range of 630km. With the dual capabilities of high energy efficiency and high safety, users can commute more freely and with peace of mind.
Conclusion:
There is no shortage of opportunists in China's auto market, but those who do things in a down-to-earth way always win in the end. From Dongfeng Fengxing, we can sense its spirit of excellence in battery safety technology. As early as before, Fengxing Thunder Armor Battery has carried out various complex challenges such as vibration, collision and pressure, and has successfully won a number of safety honorary certifications. Like the "gold medal goalkeeper" of battery safety technology, Fengxing Thunder continues to defend the bottom line of battery safety development and constantly refresh people's understanding of the safety of new energy vehicles, thereby promoting the sustainable development and breakthrough of Dongfeng Fengxing's "Photosynthetic Future" new energy strategy, creating more safe and quality-assured automotive product experiences for consumers, and driving enterprises to accelerate their efforts in the new energy track!
