Why do we need blade batteries?

Blade batteries cannot achieve higher energy density in battery materials, but they have made breakthroughs in battery system integration. This solves the shortcomings of short battery life of lithium iron phosphate batteries. This is the background for the birth of blade batteries. Part 3. BYD blade battery specifications Part 4.

How does a blade battery work?

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.

What are the advantages and disadvantages of blade batteries?

Another advantage of blade batteries is that they have good heat dissipation performance. We all know that batteries are particularly sensitive to temperature, which is also the main reason that limits battery fast charging time. Therefore, heat dissipation is a very important indicator for battery cells.

What is the difference between a module and a blade battery?

The height of the Blade Battery is reduced by ~50 mm, compared with regular LFP battery back with modules, providing more space to the passengers and decreasing the coefficient of drag (0.233 cd for BYD Han). In the Z direction, the structure of the Blade Battery is completely different from conventional module-based battery packs (Figure 3).

How high can a BYD blade battery be?

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.

What is blade battery?

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.
