BYD took the lead in achieving a breakthrough in charging technology from 0 to 1, and the world's first 800V high-voltage platform and step-up charging technology. This technological breakthrough not only provides a new solution for the power, range and charging of new energy vehicles, but also creates a more extreme electric vehicle experience for users. Specifically, BYD's 800V high-voltage platform is equipped on models such as Qin EV and Tang DM, which can accelerate the vehicle to 4 seconds, and the pure electric range can reach 450km, and the fast charging power is increased to 60kW, providing users with more powerful power and more efficient charging experience. In addition, BYD's step-up charging technology completely solves the problem of incompatibility between high-voltage models and low-voltage pile charging, and fully adapts to all DC charging piles to improve charging efficiency.
In order to solve the problem of the scarcity of public fast charging piles, BYD launched the world's first dual-gun supercharging technology for passenger cars. At present, the public overcharging piles with more than 300A current account for only 2% of the total, while the resources of public fast charging piles are sufficient. Therefore, BYD proposed a plan to transform the public fast charging pile into a supercharging pile through the uplift scheme. Through dual-gun overcharging technology, BYD's vehicles can be charged at public fast charging piles, with a maximum power of up to 230kW, and it only takes 15 minutes to charge 350 kilometers. In order to ensure the safety of charging, BYD has also adopted the world's first composite direct cooling technology, which improves the heat exchange capacity of the battery and provides users with a safe and reliable supercharging experience by designing straight cold plates on both sides and two sets of independent refrigerant control systems.
In the extremely cold conditions of the northern winter, charging efficiency is often greatly reduced. In order to solve this problem, BYD pioneered the world's first full-scene intelligent pulse self-heating technology. In the case of the DENZA N7, for example, this technology can increase the heating rate of the battery by 230%, reducing the time it takes for the battery to be fully charged. Even in extremely cold conditions of -30, users will still be able to enjoy the experience of fast charging. In addition, the full-scene intelligent pulse self-heating technology can also intelligently start in the parking and driving states to ensure the performance of the whole vehicle in extremely low temperature environments.
As a leader in China's new energy vehicle field, BYD has led the development of an all-round charging system through the world's first five major technological achievements. First of all, BYD took the lead in achieving a breakthrough in charging technology from 0 to 1, launching an 800V high-voltage platform and step-up charging technology, providing a better solution for the power, endurance and charging of new energy vehicles. Secondly, BYD pioneered the world's first dual-gun supercharging technology for passenger cars, transforming public fast charging piles into supercharging piles, improving charging efficiency and allowing users to enjoy a faster charging experience. Finally, BYD also pioneered the world's first full-scene intelligent pulse self-heating technology, which solves the problem of low charging efficiency in northern winter, allowing users to enjoy the convenience of fast charging in extremely cold conditions.
BYD's innovative technology has not only been recognized in China, but has also attracted the attention of the international market. Through continuous technological innovation and R&D investment, BYD not only provides users with a better charging experience, but also makes positive contributions to the development of China's new energy vehicle field. With the continuous evolution of technology and the wide promotion of applications, it is believed that BYD will continue to lead the development of the all-round charging system and provide users with more convenient, efficient and safe charging services.
