Safer than a fuel truck! BYD Han EV has secret weapons.

As the main means of transportation in modern society, automobile safety always ranks first. In the era of traditional fuel vehicles, automobile safety is mainly reflected in active and passive safety such as collision safety. With the rapid development of new energy and intelligent technology, automobile safety has entered the multi-dimensional safety field. So how to judge whether a new energy vehicle is safe enough? How do consumers choose their favorite new energy vehicles? Today, we will talk about how pure electric vehicles can be safer than fuel vehicles around BYD Han EV (hereinafter referred to as Han EV).

Safety is the greatest luxury of electric vehicles.

Wang Chuanfu, chairman of BYD Auto, once said, "Safety is the greatest luxury of electric vehicles". Consumers have different demands for electric vehicles, but safety is the number one enemy that hinders the better and faster development of electric vehicles. With the substantial increase in the number of electric vehicles, the risk of traffic accidents has also increased accordingly. The safety problem of electric vehicles caused by power batteries is also the main factor restricting the development of new energy vehicles. As we all know, Han EV has very strict and high standards in safety design. As one of the core components of electric vehicles, the safety of batteries largely determines the safety performance foundation of electric vehicles. The appearance of BYD’s "blade battery" has promoted the safety of batteries to a new height, and at the same time, it has also enabled Han EV to get ahead of the competition in the automobile market.

At present, the batteries of pure electric vehicles in China include Ferrous lithium phosphate and ternary lithium battery. Compared with Tesla Model 3, BYD and Tesla have completely different design styles. Model 3 uses a relatively traditional ternary lithium battery, while BYD uses a self-developed blade battery. Compared with the ternary lithium battery of Model 3, the blade battery has better stability, better cycle characteristics, safety characteristics and energy density, and longer charge and discharge life.

In many safety tests of power batteries, blade batteries performed particularly well. Among them, the acupuncture test is recognized as the most demanding test, which can be called the "Everest" of battery safety test. The results of acupuncture test are obvious. After acupuncture, BYD blade battery has no open flame and smoke, and its surface temperature is only 30-60℃.

Battery safety is highly valued, and so is voltage safety. The power battery voltage of new energy vehicles is as high as five or six hundred volts. If there is a leakage accident, it may cause serious consequences. BYD has established a corresponding voltage protection system to ensure the stable operation of high-voltage lines. Even in a serious collision accident, high-voltage power supply can be cut off at the first time to ensure the safety of consumers and rescuers.

Passive safety: Not only collision safety, BYD Han EV is more comprehensive.

Han EV has very strict and high standards in safety design. On July 21st, 2021, following the high-scoring C-IASI crash test, Han EV achieved another success, and won the C-NCAP five-star safety certification with a comprehensive score of 91.5%. As the flagship car of new energy in China, Han EV has passed the two authoritative safety tests of C-NCAP and C-IASI continuously, becoming the first new energy car with "double excellent safety certification".

The rigidity and structure of car body is an important standard to measure passive safety. On the basis of the body structure, Han EV also strengthened the design of anti-collision parts such as A-pillar and B-pillar. In the core 25% small-scale overlapping offset collision and side impact test, except for the normal deformation at the collision site, the whole cage body frame of Han EV is kept very well, and the firewall, A-pillar, B-pillar and sill beam are not obviously deformed, which shows that the passenger compartment structure is kept well and the living space of passengers is guaranteed. Han EV body structure embodies the "combination of soft and hard" in collision safety. The front cabin is fully energy-absorbed, the passenger cabin is fully supported, and so is the body material. The usage of high-strength hot-formed steel in key parts such as A, B and C columns reaches 97kg, ranking first in independent brand cars, and "really making good use of steel on the blade".

The high-strength car body keeps the passenger compartment intact in the collision, and it is also beneficial for the airbag system to open at the predetermined position, thus truly protecting the passengers. Compared with competing models Tucki P7 and Model 3 of Han EV, Han EV comes standard with 11 front double airbags, front seat side airbags, rear seat side airbags, front and rear penetrating side airbags and main driver’s knee airbags. Compared with many car companies to reduce the safety configuration of entry-level models, this shows that Han EV attaches great importance to user safety.

Active safety: technology-led, escort for safety.

With the continuous development and improvement of automobile science and technology, active safety technology is a progress and innovation in the history of automobile safety development. From the past, it relied on "seat belts" and "airbags" to passively reduce the degree of accident damage, and now it is actively preventing accidents through a large number of auxiliary scientific and technological equipment. Compared with the losses caused by accidents, avoiding accidents is an important topic of automobile safety at present.

Speaking of active safety, we have to mention a key configuration of EV-brake assist system (EBA), which is the best weapon to prevent collision. In our daily driving life, many drivers don’t have enough preparation and reaction time for unexpected situations such as "ghost probe, forced lane change", and it is easy to step on the brakes too slowly or with insufficient strength, which will cause the braking distance to be too long and lead to traffic accidents such as rear-end collision. With EBA, Han EV can monitor the front of the vehicle in real time. Once the system judges that an accident is about to happen, it will activate the brake assist and brake, which will give the driver more reaction time and avoid the accident more effectively.

The leader of new energy vehicles, the core technology lies in "three electricity"

Since its listing in July, 2020, HAN EV has been deeply favored by the public by virtue of its comprehensive leading hard-core product strength, and its sales volume has continuously led the China brand medium and large car market, and 100,000 new cars have been rolled off the assembly line on the first anniversary of its listing, creating a milestone for the upward development of new energy vehicles in China.

Compared with Tucki P7 and Model3, Han EV has an incomparable advantage: all core components of electric vehicles are self-researched. Different from traditional fuel vehicles, the core technology of electric vehicles lies in "three electricity", that is, power battery, drive motor and electronic control system. BYD has always been one of the most important suppliers of power batteries in the world. The permanent magnet synchronous motor independently developed and manufactured by BYD is also at the top level in terms of performance and efficiency. In terms of electronic control, BYD has the R&D and production capacity of IGBT and SiC chips. When almost all electric vehicle manufacturers including Tesla need to outsource such chips, this is tantamount to controlling the "lifeline" of electric vehicles.

SiC chip is the most advanced power semiconductor chip at present. In the global mass production of electric vehicles, only Model3 and Han EV use SiC chips. Different from Tesla’s outsourcing of SiC chips, Han EV is the first electric vehicle in China to apply self-developed SiC modules, which is not only the beginning of independent application of third-generation semiconductor materials, but also the beginning of this material entering high-end production vehicles. The SiC power module enables the Han EV electric drive system to maximize the power and torque, greatly improving the performance of the electric drive, and helping the whole vehicle to accelerate 100 kilometers for 3.9 seconds.

Comments on this website:After hundreds of years of historical evolution, the car has gradually changed from a means of transportation to an intelligent integrated device for life and travel. In the past, the safety of automobiles mainly depended on passive and physical protection. However, with the development of science and technology in the new era, the safety of automobiles has been promoted to a new height through active safety extended by various intelligent configurations. If the appearance value and dynamic performance are the first impressions that impress consumers, then the safety performance is the first choice for consumers. BYD Han EV has comprehensive active and passive safety equipment, black technologies such as blade batteries and auxiliary control systems, and is a trusted independent brand of consumers.
