In the face of the overwhelming "800V" of friends, BYD finally has a positive response, do you think the 800V high-voltage platform is very good?This is just BYD's technology 8 years ago.
Some time ago, there were several new cars on the market, all of which were promoting the 800V high-voltage platform, how fast the charging speed and so on. As the leading brother of new energy vehicle companies, BYD has not made any moves in this regard, and it is inevitable that people will be doubted about the strength of the three-electric system.
I don't know if it's too confident or too inflated, BYD seems to ignore the question, so that the question becomes a rumor, and finally on the morning of December 20th, BYD's official account responded, announcing 5 world's first charging technologies.
BYD pioneered the 800V high-voltage platform touted by friends in 2015 and has been installed on models such as Qin EV and Tang DM.
So you can't blame BYD for being too low-key, who will promote the technology of 8 years ago?
When friends are still using this as a selling point, BYD has engaged in multi-gun fast charging technology, which is currently the best way to solve the anxiety of energy replenishment, and the 800V high-voltage platform has no effect at all, and it can even be said to be a marketing gimmick.
Because there is a supercharging platform but no supercharging pile, the power of most domestic charging piles is less than 150 kilowatts, coupled with the factors of electric pile diversion and time period, even if your car has an 800V platform, the charging power cannot break through the upper limit of 150 kilowatts. The DENZA N7 uses dual-gun fast charging technology, and the actual charging power can reach 230 kW.
There is no doubt about Dizi's three-electric technology, the low-temperature stability of lithium batteries is quite poor, and it is easy to lie down or not charge in extremely cold weather, Dizi has its own unique solution, the world's first full-scene intelligent pulse self-heating technology, so that friends in the Northeast can also enjoy fast charging.
Take the 800V high-voltage platform as an example, this is really not an advanced technology, Dizi is already mass-producing 1200V silicon carbide, but there is no great publicity.
Although there is no universal super pile, the 800V high-voltage platform is not useless, in addition to improving charging efficiency, it can also increase output power and reduce energy consumption.
800V is twice as high as 400V electrical energy output, which can make the motor burst with more power and torque, so now more than 200,000 electric small steel cannons, as long as the zero hundred acceleration performance is overemphasized, will basically promote silicon carbide motors.
The high-voltage platform can also reduce energy loss, so the 800V high-voltage platform can achieve a longer range with the same battery pack.
All in all, 800V is not a new technology and will be widely used in the future, but it is too early to use it as a selling point.
