With the gradual growth, the desire of business trips is getting lower and lower. But every year, I still have to fight for business trips, which is BYD’s “Technical Motto” conference. It is no longer a launch of a company, while it is no longer a launch of a company, and almost represents the wind direction of the industry.
In BYD launched blade batteries, DM-I super mixed as if yesterday, BYD released a heavy innovation-BYD pure electric E-platform 3.0. So, what is the improvement of this new platform worth paying attention, how is it realized?
From the perspective of user needs, the current anxiety of new energy vehicles is still focused on security and battery life. The upgrade and improvement of BYD E platform 3.0 is based on the two core pain points of the user.
High-security
, BYD greatly enhanced the entire vehicle stiffness under the platform and reached a super five-star ability of global safety standards. Wang Chuanfu, Chairman and President of BYD Group, said, “Let the fuel vehicle have the upper limit of the structural strength, become the lower limit of pure electric vehicles.”
In the design of the pure electric vehicle structure, the safety protection of the battery has always been the focus of the engineers. BYD E platform 3.0 to the greatest subversion of industry traditional philosophy in: Let the battery also become the safety of the body structure. This is like a family child graduated from the college, and the money is turned to earn money, and it has contributed to the family.
The key to achieving this is BYD’s exclusive boxing – blade battery. BYD makes the battery itself a high-intensity structure through innovative thin film design. In this way, the battery safety is no longer a short board for the overall safety of the body, but has become a “supplier” that improves the stiffness of the vehicle. 
In principle, this seems to be very simple, but it is not easy to achieve it. Because this requirement must have the courage and ability to break the traditional design concept.

During the stream, two-way interchange On the end, based on the pure tram type of the E platform 3.0, The maximum battery will reach 1000 kilometers. And on the winter life of the user carefully, it has achieved a temperature difference in the temperature difference of -30-60 ° C by technology, which has been improved in the previous 20%. In addition, BYD also achieved a 150 km of charging by new fast-charged technology. Improve the battery life of the pure tram, the overall idea is only open source and throttle. BYD uses a dual-managed way to improve the battery life of the E platform 3.0. Open source, the blade battery is a hero. It is optimized in structure not only brings security, but also improves the volumetric energy density of the battery. What is the volume of energy?
The battery we have exposed everyday is one of the monomers, so in the impression, the larger the battery, the more energy stored. And the power battery on the car, it is a assembly, we call it battery pack. Because it is a collection of large numbers of batteries, it must be considered problems such as heat dissipation, reliability and stability, so it is a large volume in it, and it is “waste” in the energy storage.
Due to the structural optimization, the blade battery is small, the volume of energy is naturally improved. The more electric power that the unit volume can be stored, and its battery life will naturally improve. 
On the throttle, on the pure electric vehicle, the power battery not only provides power energy, but also the power source of other power supply equipment, the first rush is the winter heating power consumption. The heat of the fuel car does not require air conditioning, and the heat heating is achieved directly from the engine. At present, the pure electric car warmth is mainly relying on electric energy directly, just like electric heating in the winter, its power consumption is self-evident.
The E platform 3.0 takes a high-efficiency heat pump for the long temperature domain from the conventional fuel vehicle, and the residual heat generated by the battery and electric power assembly is treasure. For heating in the car. The heat pump air conditioner is from the role of “heat portrait”, not a calorie producer.The role thus greatly increases heating efficiency, reducing heating power consumption, and improves life.
You may have questions, since the principle of heat pump air conditioners is not complicated, why is BYD to achieve it? This is actually attributed to the system calorie control. What is it? Is that other manufacturers know the principle, it will not be able to achieve it. Because of battery thermal management, power assembly heat management, etc., it is difficult to integrate throughout. BYD’s three-electric hardware and software systems are self-developed, so it can do it.
However, as BYD achieves the amount of production, as well as the high openness of BYD, I believe this technology plan will soon be pure in other brands. Apply on the tram will also be applied.
In addition to reducing energy consumption, BYD E platform 3.0 achieves “15 minutes of charging for 5 minutes, life is 150 km”, is also worthy of our concern. It enhances the faster DC charging by increasing the charging voltage. As an electric vehicle owner, I observed the daily DC charging, the voltage is basically around 360-380V, while BYD is in the fast charge, the inner electron control system can increase the highest charging voltage to 800V, thus enhances the fast charge of more than 1 times. efficient.
Although the pure tram still can’t be like a fuel car, it will be completed in a few minutes, and the life is full. But with the progress of charging technology, such goals may not be far away.
BYD new E platform 3.0 actually there is still much worth mentioning, such as its eight-in-one power assembly, four-wheel drive architecture, hardware plug For use, the OTA upgrade cycle is shortened by two months, etc., which is limited to the space, and today will not be a delay. If you are interested, I will communicate separately with you later.
Despite our anxiety of pure tram, it seems to be multi-dimensional, not related, but in fact, whether it is safe, life is good, it must rely on systematic all-round improvement, product Less a lot, in order to achieve the amount of change, let us do not choose between the needs of the electric vehicle, “all must”.
Oil, the evolution of BYD E platform 3.0, originalIt is not particularly complex, but all must be a reality in engineering, we must systematically develop and manufacturing capabilities. This is the moat of BYD as a global new energy vehicle leader.
Understand this, we can understand why BYD’s market value can reach 80 billion heights, still have infinite.
Finally, it is very beautiful, and the new E platform 3.0 at the same time, the Oceanx concept car is very beautiful, BYD rushes, puts Model3!
