How safe is BYD’s blade battery? BYD’s blade battery demonstrates significant advantages in terms of safety. Its safety performance has been verified through rigorous multi-dimensional testing and real-world application, setting a new industry standard. The battery uses lithium iron phosphate material, which offers higher thermal and chemical stability compared to ternary lithium batteries, making it less prone to runaway in high-temperature environments and establishing a solid safety foundation at the material level.
In rigorous testing, the Blade Battery’s performance is remarkable. In the needle penetration test, when a steel needle pierces the battery cell, causing an internal short circuit, traditional batteries may burst into flames or explode. However, the Blade Battery shows no open flames or smoke, and its surface temperature remains significantly below the safety threshold, demonstrating exceptional resistance to thermal runaway.
In compression tests, the battery pack maintained its structural integrity even after being subjected to pressures far exceeding conventional standards, with no leakage, fire, or explosion, proving the reliability of its mechanical protective performance. In furnace temperature tests, the battery pack operated for extended periods in environments far exceeding conventional usage temperatures without any safety hazards, further validating its high-temperature resistance.
BYD has also established a comprehensive safety system through its ‘four-in-one’ approach, providing protection at the material, cell, pack, and vehicle levels. The CTB battery-body integration technology deeply integrates the battery pack with the vehicle structure, not only enhancing the battery’s durability but also improving the vehicle’s torsional stiffness.
This effectively reduces the risk of battery damage in collision accidents. In terms of thermal runaway protection, the Blade Battery optimises cell layout and cooling design to ensure that a single cell’s thermal runaway does not trigger a chain reaction, buying passengers valuable escape time. In practical applications, the Blade Battery’s safety has also withstood rigorous testing.
How safe is BYD’s blade battery? Vehicles equipped with this battery have performed excellently in various collision tests, with the battery pack remaining stable and no instances of fire or explosion occurring. User feedback also indicates that the blade battery demonstrates extremely high reliability in daily use, consistently providing stable power support for the vehicle.
