With the gradual warming of new energy vehicles in the world, anxiety seems to spontaneous combustion pushed to the cusp. Recently, BYD to produce a questionnaire about “Blade battery”. Blade battery will not only change the industry relies for three yuan lithium battery, while the battery is overstating the technology to more secure areas.

March 29, BYD Wang Chuanfu, chairman and president at the press conference, said: ” ‘blade battery’ will ‘spontaneous combustion’ is a word from the new Dictionary energy vehicles in an attempt to erase. “BYD, the safety of new energy vehicles has been regarded as the highest level so far has maintained a battery of new energy vehicles security zero accidents. Over the years, BYD has been committed to innovative battery safety, hoping to solve the new energy automobile security pain points, leading the world in battery technology route back to the right path.

a “thorn” pinpointing

Since the first prerequisite of new energy vehicles is high security, then we have to ask: insert the battery in the end to achieve what can be called the level of security? We know that, after a new battery out to go through a variety of safety tests on battery safety testing is up to more than 300 species, and acupuncture is a recognized test battery safety tests, “Everest”, can be said that only through prick tests can be called the king.
Currently available electric vehicle batteries are ternary lithium iron phosphate and the lithium-based and, therefore, these two blades while needling cell battery nail penetration test site, in order to more intuitive to see the battery’s performance, the test deliberately put the eggs on the three batteries. How to behave in that three battery acupuncture trials? Us see what happens.
First look now widely used in passenger cars ternary lithium battery, the temperature of the surface of the needle quickly instantaneously exceeds 500 deg.] C and severe burning starts, the egg cell surface is also blown. After
look weaker life, greater stability but conventional lithium iron phosphate battery block, acupuncture no fire, smoke, the surface temperature reaches 200 ℃ ~ 400 ℃, eggs have been burned under such temperatures.
BYD final appearance of the “Blade battery” no flame after needling, smoking, the surface temperature of the battery to maintain about 30 ℃ -60 ℃, the egg cell surface intact.

can be easily derived from the results of the nail penetration test, battery blade indeed safer than three yuan lithium and lithium iron phosphate. It can be said, by the success of “acupuncture” test blade leading global battery powered battery safety to new heights.
Experts see insert cell

that can insert the battery why stringent prick test? According to the Chinese Academy of Sciences, Tsinghua University, Ouyang Ming Gao analysis, first, the blade is based on innovative battery technology lithium iron phosphate, lithium iron phosphate, and therefore with high exothermic onset temperature, the temperature rise is slow, low heat production, no decomposition release of oxygen and other advantages, coupled with the battery cells becomes long blade thinner, also increases the surface area, is also better overall heat; secondly, a short circuit of the battery circuit is relatively long, the heat generated will be relatively small, so that the blade cell acupuncture’s performance was perfect. BYD combined with a full range of high-temperature “ceramic battery” technology, so that the safety blade battery has been greatly improved.
In addition to the high safety, long life blade further comprising a battery, two advantages of high strength.
We know that the limited space of the car, most of the use of space left to the consumer needs, space on the battery It is continually compressed, the battery can only be arranged in the most limited space to allow the vehicle to have a higher life. And the blade length of up to 2 meters because of the battery, but thin thickness, when the group can be skipped “module”, composed of the battery pack directly, compared to a conventional space utilization of the battery pack 50 to enhance the percentage, in the same space you can install more batteries, lithium batteries and thus on the shoulder three yuan mileage.

Meanwhile, the battery depending on the shape such as a blade insert, “blade side” will has a high strength, desired bending is not easy. And the battery pack from the battery 100 or more blades composition, which is high strength 100 itself will serve as a battery cell pack “beam”, in the upper and lower surfaces andTwo high strength of the plate is provided, formed in conjunction with 100 “beam” plus two strength of the panel, so that their strength is further enhanced.
[123 ]
From this, BYD “blade battery” to prove safety and life can have both the industry in battery technology, new energy vehicle development, once again demonstrated his the strength can be said to be a near-perfect battery industry is a major innovation. Of course, to achieve such breakthroughs in core technologies occasion, BYD also want to allow consumers to benefit, will share core technologies and open parts industry, which can be described as a great boon for the country’s new energy vehicle development is.

BYD Group Vice president and Chief Verde battery, chairman of He Long, said: “you can think of almost all car brands, and we are exploring cooperation program based blade battery technology, I believe we will soon be able to see, hear blade battery more exciting news. “
the Chinese BYD off knives
known, “good knife” with “hero.” After all, BYD is a vehicle manufacturer, according to Mr. Wang said the site, the first to carry the blade battery used in BYD Chinese EV, other vehicles No planning. Therefore, the Chinese BYD EV will not only become the field of new energy passenger cars with the highest safety attributes, but also provide more power output and acceleration, 0-100km / h acceleration takes only 3.9 seconds, the highest life achievement 605km, comprehensive quality located in the leading position in the field of new energy passenger cars.

summary:
when the industry all three yuan lithium battery in the endless pursuit of the high-density, high-endurance, BYD has always put safety first, adhere to the higher stability of lithium iron phosphate battery research and development, and continue innovation in technology. The blade of the battery, it not only allows battery technology back on track, will also help speed again travel the world’s new energy industry.
security responsibilities from early heart to explore the endless, BYD battery blade in the date of birth was high hopes. Responsible for its future mission, the bottom line to defend the safety of new energy vehicles, this is the most valuable.
