Japan's Toyota solid-state battery is charged for 10 minutes and travels 1200 kilometersWhat about BYD?
Toyota is the hegemon of the world's automotive industry, and it is still one of the largest automotive conglomerates in the world in terms of car production and sales, but there is one fact that cannot be ignored: Toyota's global market share is growing relatively slowly, or even declining.
Especially in the Chinese market, Toyota is facing unprecedented challenges, mainly due to the rapid growth of new energy vehicles in China, which has gradually lost the attractiveness of traditional fuel vehicles.
Toyota seems to have been dismissive of new energy vehicles, so it has missed the best opportunity to develop new energy vehicles. Now, Toyota suddenly repented and began to increase the research of new energy vehicles, especially the research on batteries, and the research on solid-state batteries has also made certain technical progress.
In July of this year, Toyota suddenly announced a breakthrough in battery technology, planning to launch cars with advanced solid-state batteries by 2027, claiming that cars with solid-state batteries can charge in just 10 minutes or less, but have a range of up to 1200 kilometers.
If this technology becomes a reality, it will set off a new revolution in new energy vehicles, and the pace of new energy vehicles replacing fuel vehicles will also accelerate.
Seeing this, many people sweat for China, and even worry that China's new energy vehicles, which have been in the leading position, will be surpassed by Japan
In fact, one should not worry about it.
On the one hand, the solid-state battery technology announced by Toyota is still in the research and development stage and has not yet been put into mass production, so its actual performance has yet to be tested.
On the other hand, Japanese companies continue to make progress in battery technology, and Chinese companies are not far behind, from a practical point of view, the battery technology of Chinese companies is more practical, especially some Chinese companies represented by BYD have actually been in a leading position in battery research.
As we all know, BYD has developed rapidly in recent years, and has now become the largest domestic brand in China in terms of sales, and has successfully ranked among the top ten automakers in the world.
The reason why BYD has been able to achieve such results is mainly due to the accumulation of the past few decades, as well as continuous research and development and innovation, especially the accumulation of battery technology, which is one of the important driving forces for BYD's rapid development.
When it comes to BYD, many people may only know that it is a car manufacturer, but in fact, BYD was founded to produce batteries, at the beginning of the main production of mobile phone batteries, at that time it was still Nokia's first business, so far BYD has been working in the field of batteries for nearly 30 years.
In 2003, BYD officially entered the automotive industry and aimed at new energy vehicles from the beginning. BYD has taken advantage of its own accumulation and advantages in battery technology to become one of the earliest enterprises in China to enter the field of new energy vehicles. At the beginning, BYD attached great importance to the research of new energy vehicle batteries, and made a number of breakthroughs, taking the lead in achieving a breakthrough from 0 to 1, creating a complete charging system, and launching five pioneering technologies to solve charging problems, including 800V high-voltage platform, fast charging technology, dual-gun supercharging technology, direct compound cooling technology and pulse self-heating technology.
Among them, BYD is the first company in the world to produce 800V high-voltage platforms.
In the early days of the popularization of new energy vehicles, the new energy vehicle industry faced many challenges, such as insufficient power, short mileage, slow charging speed, etc., and the user experience was poor.
In order to solve these problems, BYD invested heavily in research and development, and finally achieved a technological breakthrough in 2015, pioneering the world's first 800 V high-voltage platform for passenger cars, which was 2-3 generations ahead of the industry at the time.
Once the 800V high-voltage platform is applied to new energy vehicles, the user experience will be significantly improved: on the one hand, the technology can accelerate to 100 kilometers in just 4 seconds;On the other hand, the charging range is up to 450 km, and the charging power is increased to 60 kilowatts.
It's just that when this technology was launched, it also faced new challenges, because at that time, 95% of the domestic low-voltage battery charging voltage was below 500V, which was incompatible with the 800V high-voltage platform, which affected the charging efficiency. In order to solve the compatibility problem, BYD pioneered pulse charging technology in the world to realize the compatibility of low-voltage rechargeable batteries with high-voltage platforms, and fully adapt to all DC rechargeable batteries. In order to solve the compatibility problem, BYD pioneered the world's first pulse charging technology to achieve the compatibility of low-voltage rechargeable batteries and high-voltage platforms, and fully adapt to all DC rechargeable batteries.
After the breakthrough in this technology, many automobile companies have equipped 800-volt high-pressure drilling rigs, which has played a very important role in promoting the development of the new energy vehicle industry.
Of course, in addition to the 800 V high-voltage platform, BYD has also pioneered the world's first dual-gun supercharging technology for passenger cars, which turns ordinary charging piles into super fast charging piles in seconds, greatly improving the charging efficiency of ordinary charging pilesIn order to make this charging technology safer, BYD also pioneered the world's first composite cooling technology to ensure the safety of ordinary charging piles turning into super charging piles.
In addition, in order to solve the problem of greatly reducing the charging efficiency in the northern winter, BYD also pioneered the world's first full-scene intelligent pulse self-heating technology, which can still achieve fast charging even in extremely cold weather conditions. For example, in severe cold conditions of minus 30 degrees Celsius, the DENZA N7 equipped with all-scenario intelligent pulse self-heating technology has a 230% heating speed and a 30% shorter battery charging time than traditional solutions, greatly improving the user's charging experience.
In addition to these technologies, BYD also has many basic technologies in the fields of batteries and battery management systems.
These technologies have been translated into practical results, and they are more in line with the current national conditions than many of BYD's models, and this technology is also more practical than Japan's Toyota, which has announced that it will be equipped with a solid-state battery with a range of 1,200 kilometers in 10 minutes by 2027.
The most important thing is that BYD's technology is constantly evolving, in addition to the traditional liquid battery, everyone is also concerned about BYD's solid-state battery;As for the extent of BYD's research and development of solid-state batteries, BYD did not disclose, but the research on solid-state batteries is no longer a secret.
And compared to other companies, BYD is more stable in battery research. BYD's general direction in terms of batteries has always been in the direction of blade batteries, semi-solid-state batteries, and all-solid-state batteries, and we will not be upset if one day BYD suddenly announces that solid-state batteries will be mass-produced.
In order to continue to maintain China's leading position in the field of new energy vehicles, some Chinese companies represented by BYD will continue to build more advanced charging systems through R&D and innovation to maintain China's leading position in the field of new energy vehicles.
