advantage of LiFePO4 BYD Blade Cell (3.2V/102Ah C103F）：
1. Increased battery energy density：
The blade battery cancels the module design and reduces the design of many structural parts.
At the same time, the upper and lower boxes are closely connected to the battery core, which significantly improves the volumetric energy density. This is also BYD’s widely publicized 50% increase in volumetric energy density.
2. Low cost：
The blade battery cancels the module design and optimizes the battery structure design. The number of secondary battery components has been reduced by 40%, and the low-cost LFP system has been applied, effectively reducing costs.
3. Strong structure：
The blade battery PACK is designed on the upper and lower sides of the battery cell, and two high-strength strength plates are bonded using structural adhesive. This creates a structure similar to a honeycomb aluminum plate, allowing each cell to act as a structural beam. Traditional battery packs generally only have 4-5 beams, while blade batteries allow each cell to act as a structural member, so its strength can be imagined. When there is a collision at the bottom of the battery, the battery core can directly withstand a certain range of force.
4. Excellent thermal management：
The liquid cooling plate of the blade battery is arranged above the battery core. At the same time, a thermal conductive layer is designed between the battery cores. The heat exchange area of this solution is much larger than that of traditional prismatic battery cells. It can effectively transfer the heat of the battery core to the water-cooling plate.
In addition, the blade battery has good heat dissipation performance, so the heat pipe of the blade battery is excellently designed and can control the maximum temperature difference within the battery within 1 ℃. The current industry standard is 5 ℃
5. Platform ization：
Blade batteries come in different specifications. Its length can be changed between 347~1012mm. In addition, it is a standard flat-type battery pack. Blade Battery can change the size of the battery pack in the X and Y directions according to the vehicle space, and develop batteries of different specifications.
This platform-based battery effectively reduces development costs and time. Its patent shows that there are at least 8 types of blade battery solutions. And corresponding to different sizes of batteries and different arrangements, the double-layer battery solution is also considered. For the integration of the cabinet, there are traditional separation solutions of the chassis and the cabinet, and there are also integrated chassis solutions in which the two are integrated into one.
The life of BYD blade battery is determined by the number of cycle charges and calendar life.
Cycle charge times:
Byd blade battery cycle charge is about 3,000 times. It should be noted that not every charge counts as a complete cycle, such as from 20% charge to 100%, the next time the same state charge to 100% counts as a complete cycle .
Calendar life and influencing factors:
The official life of the calendar is around 8-12 years, depending on the specific life span
In the use environment and habits:
Loss of power : long-term loss of power will accelerate battery decay.
charging mode : Fast charging mode has greater impact on battery decay than slow charging mode.
Driving mode : Battery decay faster in high-power long-term sport mode than in normal power economy mode .
Performance in actual use:
After more than 3,000 charge and discharge cycles, blade batteries can still consume less than 80% of the original power, demonstrating excellent durability and stability 23. In addition, the blade battery has a single driving range of 500-600 km, with a total driving range of up to 1.2 million km .
Blade battery advantages and features:
Using lithium ferrous phosphate technology, blade batteries have the following advantages:
high safety : thermal runaway temperature of more than 500 degrees Celsius, can effectively resist deformation, extrusion and puncture, reduce the risk of battery internal short circuit .
high energy density : compared with terpolymer lithium batteries, blade batteries have more advantages in energy density, and a single endurance range of up to 500-600 kilometers 2.
strong durability : in the low temperature environment, the battery life of the blade will be affected, the temperature reaches zero, the battery capacity of up to 70%, minus 10 degrees, only 50%.
Conclusion：
BYD blade batteries, with their excellent performance and long life, provide strong support for the development of new energy vehicles.
