The tiger is not powerful, when I am a sick cat?
This sentence is used to describe BYD's promotion on the 800V platform.
Starting in 2023, the new mid-to-high-end pure electric vehicles in China have begun to intensively use the "800V platform" as a selling point, while BYD's new models rarely focus on the 800V platform.
Over time, many people mistakenly think that BYD does not have "800V" technology, after all, the wine fragrance is also afraid of deep alleys in these years. So this time,BYD chose not to be low-key, it's time to blow a good wave
In fact, as early as 2015, that is, 8 years ago, BYD has launched the industry's first 800V high-voltage platform for passenger cars, creating DC boost charging technology, with a fast charging power of up to 60kW, which was first used in Qin EV in 2015.
Then, in 2020, BYD launched the second-generation 800V high-voltage platform, which pioneered the electric drive boost charging technology, with a fast charging power of up to 100kW, which was first used in the Han EV model.
In 2022, BYD's 800V high-voltage platform has been upgraded to the third generation, and it is the first oil-cooled electric drive boost charging technology, which is installed in seal models.
Therefore, for BYD, the 800V platform has long been not a sophisticated technology, and there is not much worth talking about. Just like the new mobile phones that come out now, they are basically all 5G, and the 5G standard is difficult to become the selling point of the current new mobile phones.
In addition, there are too many technologies that BYD can come up with to "blow", such as CTB and Yunyuan, so in the eyes of BYD's engineers, 800V is really not worth mentioning. It's just that when everyone is promoting 800V, BYD can no longer be indifferent, after all, silence is not necessarily golden, it may also be a misunderstanding.
If the timeline goes back to 2008, BYD has already equipped a 2KW 220V home AC charging solution on the F3DM, which does not rely on professional charging stations.
At that time, there was no complete set of passenger car charging technology standards in the industry, and BYD could be said to be "crossing the river by feeling the stones". The reason why it is set to 2KW is because the safer household current is 10A, which is multiplied by 220V and is about 2KW.
In 2010, BYD launched the market-oriented pure electric vehicle model E6, which adopts a self-developed 8-core DC charging interface with a DC charging power of up to 30kW. Since then, BYD has also become the first batch of Chinese EV charging standards to draft units.
If there is no standard, then become the standard-setter.
In 2011, BYD launched a 10kw vertical household DC charging pile. In 2013, BYD brought 33kw wall-mounted AC charging pile, in addition, the first three-phase high-power AC fast charging pile in China has been developed, with 40kw charging power.
As the "grandfather" of the popularization of passenger car charging technology in China, and one of the drafters of charging technology standards, BYD's fast charging technology accumulation is beyond doubt.
Although many mid-to-high-end pure electric vehicles use 800V high-voltage platforms, only 2% of public supercharging piles with currents of more than 300A in China are now available. Most public charging piles only have an output of 60kW or 120kW, and 800V models are difficult to exert their full strength, although they can "grab power" faster.
So in addition to 800V, BYD has a lot of other problem solving ideas. The first is the dual-gun overcharge, taking the DENZA N7 as an example, the maximum power of the dual-gun overcharge can reach 230kW, and the charging time is 350km in 15 minutes, so it is not too dependent on high current.
In addition, in response to the extreme cold and low charging efficiency in the northern winter, BYD pioneered the all-scene intelligent pulse self-heating technology, which increased the battery heating rate by 230% compared with the traditional solution and reduced the battery full time by 30%.
Build a charging technology system that is more in line with the current national conditionsThis is the goal pursued by BYD's charging technology.
Whether it is 800V or dual-gun overcharging, the purpose is to improve the actual car experience of consumers. After all, the last thing to look at is the curative effect, regardless of whether he is a white cat or a black cat, and if he catches a mouse, he is a good cat.
