The high-voltage wiring harness and sensors of the blade battery are in the Y direction of the battery cell. Therefore, the upper box can be in direct contact with the battery core. This allows the blade battery to save 10~20mm in height compared to batteries of the same specification.
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.
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
Therefore, the upper box can be in direct contact with the battery core. This allows the blade battery to save 10~20mm in height compared to batteries of the same specification. BYD's blade battery height design goals are 105mm for passenger cars and 120mm for SUVs.
The battery with higher mileage is what people need, and the blade battery can well solve the anxiety of most people. For instance, BYD Han EV with a blade battery has a range of 605 kilometers under comprehensive working conditions. The cost of the blade battery is much cheaper than the ternary lithium battery.
