BYD's Blade Battery is revolutionary in several ways. We're happy to explain why that is, and the importance of the so-called fingernail penetration test.
Improved safety:
Preventing thermal runaway: The blade battery adopts a special design. By dispersing the battery cells in the aluminum alloy heat sink, it effectively improves the heat dissipation effect of the battery pack and reduces the safety risks caused by overheating.
Safety accident prevention: In the collision test, the blade battery showed better safety performance, reduced the risk of battery penetration and battery short circuit, and improved the overall safety of the vehicle.
Energy density and range improvement: The design of the blade battery reduces the connection and isolation materials between the battery cells, increases the energy density of the battery pack, and thus improves the range of electric vehicles. This design also helps to reduce the weight of the battery pack, which has a positive impact on the overall performance and efficiency of electric vehicles.
Manufacturing cost and efficiency: Because the design of the blade battery simplifies the production process, reduces the use of materials and the complexity in the production process, it helps to reduce the manufacturing cost of the battery. At the same time, this design also improves production efficiency and helps to meet the growing demand of the electric vehicle market.
Environmental protection and sustainability: BYD's blade battery uses more environmentally friendly materials and production processes, which meets the requirements of modern society for sustainable development. The battery design also helps to improve the recycling and reuse rate of batteries, reduce the waste of resources, and thus reduce the negative impact on the environment.
One of the most important parts of an electric vehicle is the battery system. After years of study, research and development, BYD finally came up with the Blade Battery. What's so special about this system? The Blade Battery takes safety, durability and performance to new levels and improves battery space utilization.
Another unique selling point of the Blade Battery - which actually looks like a blade - is that it uses lithium iron phosphate (LFP) as the cathode material, which provides improved safety compared to traditional lithium-ion batteries. LFP naturally has excellent thermal stability and is essentially cobalt-free. LFP is also a very durable material.
For more than two decades, BYD has been a pioneer in battery technology. In 27 years, BYD has produced more than 3 million battery-powered vehicles for customers and has become a market leader in this field. BYD's breakthrough innovation Blade Battery, launched in March 2020, was born out of this relentless research and development and has achieved major progress in the electric vehicle industry.
One of the main concerns in the electric vehicle field is battery safety. The Blade Battery was developed for maximum safety while providing excellent strength, range, life and power. It is an ultra-safe battery with an ultra-durable structure while also providing ultra-long range and ultra-long service life. The longer, flatter design improves the space utilization of the battery pack, thereby enhancing safety.
Nail penetration test
The Blade Battery has been put through the most rigorous safety tests, exceeding the requirements of the nail penetration test, the most stringent method for testing thermal runaway in batteries. The test simulates the aftermath of a serious traffic accident and is considered the "Mount Everest" in battery testing.
During the nail penetration test, the Blade Battery did not smoke or catch fire, with surface temperatures reaching only 30 to 60 degrees Celsius. It also withstood other extreme test conditions, such as being crushed, bent, heated to 300 degrees Celsius in an oven, and overloaded by 260 percent. None of these resulted in fire or explosion, making the BYD Blade Battery a safe leader in the booming electric vehicle market.
Efficiency and extended range are other advantages of the Blade Battery, offering higher power density for optimal performance and efficiency, including faster charging. BYD CTP (Cell to Pack) technology is unique, with the Blade Battery increasing space utilization by 50 percent. This increases energy density and allows more batteries to be used in a compact space with a longer driving range. The Blade Battery's "honeycomb aluminum" design also provides greater rigidity and safety. BYD Tang, BYD Han and BYD ATTO 3 are all equipped with blade batteries.
