What is a blade battery?
The blade battery is a lithium iron phosphate battery for electric vehicles. The battery cell has a special design with a common length of 96 cm and width of 9 cm, so it’s like a blade and can be inserted into the battery pack.
While the standard LFP battery contains the structure of cell, module, pack, the design of the blade battery pack eliminates the battery module, which saves more space and thus greatly increases the space utilization and power density.
When assembling battery packs with blade batteries, the inherent strength of the blade battery is leveraged to reduce the size of crossbeams and other components within the battery pack. Under random vibration loads, the deformation of the module is significant, while the deformation of the blade battery cells is minimal.
For non-module battery packs, by modifying the structure of the battery pack, the rectangular batteries are arranged vertically and inserted into the pack, simplifying the battery pack structure and improving the utilization of internal space.
What about the safety ?
The blade battery successfully passed the nail penetration test and maintained a low surface temperature with no smoke or fire emissions. But its safety credentials go beyond that. The battery was tested in seven safety dimensions, including internal and external short circuits, overcharging, collisions, high pressure, connections and hazardous gas assessments. It also successfully passed collision simulation and crush tests.
How is the performance?
In terms of the performance of the blade battery, its high energy density provides enhanced endurance, with a maximum charging power of more than 230 kW. A mid-size vehicle equipped with BYD’s blade battery can easily exceed 700 km in range. In addition, the battery pack uses a wide-temperature efficient heat pump system and direct cooling and heating technology, which enables rapid temperature rise at low temperatures to meet driving demands.
What are the advantages?
The cost-saving aspect of the Blade battery is remarkable. As the main focus of development in the new energy vehicle sector shifts from simply increasing range to safer and smarter solutions, the lower cost advantage of lithium iron phosphate becomes increasingly important. By consistently reducing costs, the blade battery solution improves volume utilization by 50%, reduces component costs by 45%, and lowers overall costs by over 30%.
What are the applications?
In terms of applications, the Blade battery is not limited to passenger cars; it is also suitable for electric buses, vans, light-duty trucks, and heavy-duty trucks. For example, a light-duty truck equipped with a 45 kWh Blade battery pack can travel up to 280 kilometers on a single charge, making it ideal for urban delivery applications.
