The most talked-about topic about new energy vehicles is battery safety. All car companies talk about battery safety all the time and have done a lot of targeted tests. Obviously, everyone knows the importance of battery safety. Logically, everyone uses batteries that can pass various rigorous tests, so why do electric vehicles often catch fire and explode?

Are those laboratory tests on batteries, such as puncture, drop, soaking in water, and squeezing, all fake? Not really, but this eye-catching test does have certain limitations. First, the focus is on the individual battery packs, and second, the test items are too "experimental" and are all safety performance in specific scenarios, which inevitably gives the impression of being "exam-oriented".

To put it bluntly, the performance in the laboratory is one thing, and driving the car on the road is another thing. After all, the scenarios encountered in daily car use are much more complicated than those in the laboratory. Therefore, being able to pass the laboratory safety test can only be regarded as passing the passing line, and it does not reach the safety level required for daily use.

The most advanced battery safety design is "car-battery integration". What does it mean? When studying batteries, the battery and vehicle design should be integrated together. The battery safety design should have the concept of the vehicle, and the vehicle safety design should take the battery into consideration. Safety is a whole. The Luban battery used in Dongfeng Nissan Venucia is a typical example of this innovative design concept.

Simply put, the core highlight of Luban Battery is that it has opened up the safety system of the battery, vehicle and cloud. On the battery side, all tests on the battery cells far exceed the national standards, and no fire or explosion when squeezed are basic operations. More importantly, it also has a 24-hour battery monitoring system, an intelligent constant temperature thermal management system, and a special flame retardant protection design for the battery cells.

It can be seen that it basically covers the three lines of defense of "front, middle and back" when the battery encounters dangerous situations. It mainly focuses on early monitoring and will intelligently issue an alarm if there is an abnormality; when the battery has an unavoidable short circuit, the battery cell will be able to prevent explosion and fire; even if the danger breaks through the first two lines of defense, it can also flame retard the battery cell where the accident occurred to prevent the spread of thermal runaway.

The design concept of the whole vehicle is relatively simple and crude. Whether it is the design of structural reinforcements, the use of ultra-high-strength materials, or welding technology, the core purpose is to be strong and tough, and to provide all-round protection for the battery pack through the ultra-strong body structure.

As for cloud operations, they rely on data platforms and use big data for intelligent computing to monitor the various states of the battery in real time, including battery health status and even abnormal power levels, and can provide early warning of safety risks.

Battery side - vehicle side - cloud side, with this combination of punches, Luban Battery has the confidence when talking about safety, and the safety effect is indeed very good. The safety effect of Luban Battery is most directly reflected in the Venucia VX6.

The fundamental cause of electric vehicle fires and explosions is thermal runaway that occurs after a battery cell short circuits. Unlike the laboratory environment, the humidity, temperature, and even impact angles during daily use of the vehicle are completely different. The scenarios that can cause a battery short circuit are also complex and diverse. Only by breaking away from the constraints of the laboratory and returning to the life scenes of ordinary people can we test the authenticity of battery safety.

The scenarios that can cause battery short circuits are basically focused, and the most common ones are: heavy rain soaking the streets, water entering the battery causing a short circuit; violent collisions damaging the battery structure causing a short circuit; and a sudden increase in external temperature causing a structural short circuit in the battery. Will these challenges pose a threat to the Venucia VX6 equipped with Luban batteries?

Recently, torrential rains hit the country, and roads were flooded in many places. In such extreme conditions, can electric vehicles pass through? The waterproof level of the Venucia VX6 is IP67, which is at the mainstream level in the industry. It can pass through a 70cm deep waterway at a speed of 10km/h, which basically meets the standard of a hard-core SUV, and the Venucia VX6 can pass safely.

The fire road test focuses on whether the battery can withstand the ultra-high temperature environment. The Venucia VX6 drove slowly through a fire road close to 1000℃ at a speed of no more than 10km/h. The high temperature did not cause any impact on the vehicle, and the battery protection measures were still in place.

The last bottom-scraping test is the most likely to occur. Due to the particularity of the battery installation position, an occasional bottoming may cause battery damage. The Venucia VX6 is not only equipped with an aluminum alloy battery cabin, but most importantly, it also has double-layer armor protection at the bottom. More than 95% of the damage from the bottom-scraping impact will be borne by the armor. When the chassis of the Venucia VX6 scraped against a 220mm high roadblock at a speed of 50km/h, under this force of impact, only the chassis armor was slightly scratched, and the battery was not touched at all.

In conclusion:

When talking about new energy vehicles, we must talk about battery safety. When everyone focuses on the overall battery, the Luban battery, which looks at the problem from a different angle, is really eye-catching. The system combination of the battery side, the vehicle side, and the cloud side has realized the concept of "vehicle-electric integration". The design concept is unique in the industry, especially after watching the scene practical test of the Venucia VX6, you can better appreciate the advantages of vehicle-electric integration. It is said that good wine needs no bush, so the question is, since Venucia has such a good Luban battery, why do you keep it hidden and not promote it?
