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
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.
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.
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).
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.
This improves energy density and allows more batteries in a compact space, with a longer driving range. The 'honeycomb-like aluminum' design of the Blade Battery also provides greater rigidity and safety. The BYD TANG, BYD HAN and BYD ATTO 3 are all equipped with a Blade Battery.
The BYD blade battery is a lithium iron phosphate (LFP) battery for electric vehicles, designed and manufactured by FinDreams Battery, a subsidiary of Chinese manufacturing company BYD. The blade battery is most commonly a 96 centimetres (37.8 in) long and 9 centimetres (3.5 in) wide single-cell battery with a special design, which can b…
