This year, when the brands hyped the 800V platform, BYD was silent, because as early as 2015, BYD had already put 800 volt high-voltage platform technology on the shelves, and it was equipped on the 2015 Qin EV and Tang DM models, which was really the world's first, and Porsche was the first to keep up four years later, when the whole industry was low voltage, only BYD was high voltage, and developed the world's first boost charging technology, which is also the reason why BYD's car does not pick piles, 8 years later, in 2023, there are millions of fast charging piles on the market, but there are only 2 supercharging piles%, so BYD not only launched the boost scheme, but also launched the boost scheme, which is the dual-gun fast charging technology, Denza N7 dual-gun fast charging, the maximum power can reach 230 kilowatts, and it can be charged 350 kilometers in 15 minutes on all public fast charging piles, this scheme can make the fast charging pile become a supercharging pile in seconds, which is good for users and charging providers.
How to ensure the safety of the boost and continue to charge at high power stably, BYD has pioneered the world's first composite direct cooling technology, laying refrigeration plates on the upper and lower sides of the battery, and equipped with two sets of independent control systems for refrigerant, increasing the cooling area of the battery by 100% and increasing the heat exchange capacity by 85%. In the winter test, why does BYD's car charge so fast, this has to mention BYD's another world's first technology, intelligent pulse self-heating, so that the battery heat rate is increased by 230%, and the battery full time is reduced by 30%, and this technology can not only self-heat when charging, but also can intelligently start self-heating in the parking and driving state.
It can be seen that BYD's five world's first technologies are the most practical charging solutions in combination with national conditions, and BYD has been deeply involved in electric vehicle technology for 20 years when others don't know what an electric vehicle is.
