Blade battery is a new type of battery based on lithium iron phosphate (LFP) chemical system. What makes it unique is its "blade"-shaped battery cell design.
What is a blade battery?
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 be placed in an array and inserted into a battery pack like a blade. It is made in various lengths and thicknesses.
What is the length of a blade battery?
The length of a blade battery is between 600-2000mm.nSince the length of the blade battery is the same as the width of the battery pack, it covers almost all the width dimensions of the battery pack of a passenger car. Moreover, the blade battery also supports modded battery packs, thus supporting larger vehicles.
What is a BYD blade battery?
The blade battery was officially launched by BYD in 2020. BYD claims that compared with ternary lithium batteries and traditional lithium iron phosphate batteries, the blade battery holds advantages in safety, range, longevity, strength and power.
What are the peripheral components of the blade battery?
The peripheral components of a blade battery occupy the internal space of the battery pack, including the liquid cooling system and thermal insulation materials. Judging from the history of electric vehicle temperature control solutions of electric vehicle companies, they have basically developed from air cooling to liquid cooling.
Can a blade battery be overcharged?
The blade battery also passed other extreme test conditions, such as being crushed and bent, being heated in a furnace to 300 °C (572 °F), and being overcharged by 260%. None of these resulted in a fire or explosion.
How hot does a BYD blade battery get?
BYD claims that, in the nail penetration test, the blade battery emitted no smoke or fire after being penetrated, and its surface temperature reached only 30 to 60 °C (86 to 140 °F).
