Under the epidemic situation, health and safety have become the top priority of all needs, and based on the consideration of travel safety, people are increasingly inclined to travel by car. Not long ago, the lottery results of the new passenger car were announced. For the lucky ones who just got the index, how to choose a reliable car is very important.
As the main model in the market, the epidemic prevention and sterilization capabilities of brand new, BEIJING EU5 and brand new have reached the professional level, and brand new has become the leader in the compact pure electric family car market with its strong and numerous fan base. So if you want to choose a safer, stronger and more practical one among these three cars, who will be the better option?
Who is the strongest in protecting health and professional sterilization and antivirus?
To be healthier and safer, we must first have stronger sterilization and antivirus ability. The newly equipped three-layer high-efficiency composite filter screen can filter dust, harmful gases, PM2.5 particles with a diameter of > 0.3 μ m up to more than 90%. Its filter screen consists of non-woven fabrics and chemical fibers, and is made by melt-blowing process, which can better filter droplets and particles with diameters greater than 0.3 μ m that germs often attach to, thus effectively blocking germs from entering the car. In addition,BYD’s self-developed high-efficiency filter has obtained the first batch of "CN95" certification of the highest level of automotive air-conditioning filter filtration, and will be fully equipped with this system for more old models in the future to further improve health and safety performance.
At present, the filtration system carried by EU5 has been upgraded on the basis of filtering pollen and PM2.5; On the other hand, a UVC deep ultraviolet optical anti-virus system was installed for Ei5, but there are still concerns that "ultraviolet anti-virus will have adverse effects on human body" in the market at present. It is not difficult to see that the new health care is more professional and leading.
Guarding safety, the brand-new Qin EV power battery has a 16-year accident.
If health is a higher demand of consumers, then the demand for vehicle reliability is the basic demand of all consumers. In the world, this basic requirement includes the reliability of endurance, the reliability of battery, and the reliability of the overall performance of the vehicle, etc. If the technical performance of any aspect is not strong enough, there is no way to talk about safety, and no one can trust a brand of new energy vehicles with frequent vehicle spontaneous combustion.
From the comparison of the above figure, the brand-new battery has higher energy density and can store more electricity per unit volume, so its comprehensive endurance is stronger, and at the same time it can have more room for lightweight.
While continuously improving the energy density, a 7-dimensional and 4-layer safety matrix has been built for brand-new power batteries, which "comprehensively tests the safety of single batteries, modules, battery packs and systems from the aspects of reliable connection, high-voltage protection, collision, overcharge, internal and external short circuit and thermal runaway; The high-voltage system has undergone five tests: leakage detection, power-off protection, misoperation protection, active discharge and passive discharge, and the whole vehicle has undergone extreme cold and heat tests, which fully guarantees the safety of the battery. "
If these terms seem hard to you, then the accident in 16 years will definitely make you easily realize the reliability of the battery.The accident in 16 years first benefited from BYD’s technical advantages in battery safety design.In order to avoid the thermal runaway of the battery caused by the short circuit in the battery caused by the contraction of the diaphragm at high temperature, a ceramic diaphragm with more high temperature resistance was developed. In order to cope with high and low temperature environment, prevent overcharging, improve fast charging safety and flame retardant, etc., many special additives are added to the electrolyte solution of the battery cell on the basis of the original solute and solvent to ensure the stability under various complex conditions; In addition, in order to protect the safety of the battery cell, a mechanical device, including a CID device and an explosion-proof valve, is arranged on the shell of the single battery cell to prevent overcharging. These technical advantages are integrated into the battery intelligent temperature control management system, which is not only smarter, but also greatly improves the consistency and stability of products.The new Qin EV is equipped with BYD’s third-generation battery intelligent temperature control management system, which can make the battery in the most efficient working range at various ambient temperatures, greatly improving the battery life cycle performance, life span and safety.
Secondly, the accident in 16 years can be achieved thanks to all the self-research and self-production of the three power systems. Compared with peers, it has higher integration, more advanced consistency and integrity, and a stronger degree of systematization.BYD’s brand-new Qin EV efficiently integrates the motor, electronic control and transmission, which reduces the volume by 30% and the weight by 25%, while increasing the power density by 20%.
EU5 and Ei5 are made in Contemporary Amperex Technology Co., Limited, and although they have passed the battery safety test, the integration is not enough, and the consistency and integrity of products are different, so the stability performance in practical use is relatively average. For example, the dry-wet separation thermal management technology of batteries carried by EU5 is said to be effective in preventing combustion and explosion, but an EU5 exploded in Zhenjiang last September. At the same time, there are also car owners who feedback Ei5 battery failure on the car quality network.
In addition, the brand new has a stronger fan base. As of now,Qin series models have accumulated more than 200,000 fans, and have made remarkable achievements in sales volume, quality and word of mouth.,At this point, the brand-new performance is more ahead of. As a model, last year, some car owners reported on the Internet that it had a nominal battery life of 410 kilometers and actually traveled at full power for 210-220 kilometers. Therefore, in terms of endurance authenticity, brand-new is more reliable.
From the above comparison, we can see that a truly safe new energy vehicle is armed from the inside out to the "teeth", and the basis of this "armed" is the comprehensive technical strength, and the brand-new safety is based on this. It is this technical strength that has been recognized by more peers. It is said that the new factory invested 8.5 billion yuan will be used to produce and cooperate with products under the e platform.
Summary:
Changes in consumer demand after the epidemic will require higher safety, health and intelligence. Choosing a healthier and safer car will become one of the core needs of consumers around the world. At the same time, a truly leading new energy vehicle is that it understands the needs of consumers enough, and the leading comprehensive strength and proper configuration are the real masters. In the field of new energy compact family car, brand-new has really set a benchmark!
