BYD has launched four new electric vehicles using its blade battery form factor and plans to use the technology in all its future EVs.
The lithium iron phosphate (LFP) Blade Battery completed an extreme strength test that saw it being rolled over by a 46-ton heavy truck as well as nail penetration tests.
This uses the same idea as an embedded computing blade in a rack. The individual cells are arranged together in an array and then inserted into a battery pack. This structure increases the available space by over 50 percent compared to conventional lithium ion battery cells, which compensates for the lower energy density of using LFP.
The heavy truck pressure test is a BYD safety standard that is more stringent than the national standard. The test itself saw a 46-ton fully loaded heavy-duty truck drive over the Blade Battery pack, which the battery successfully passed without leakage, deformation or smoke, coming out perfectly intact and ready to be used in an EV.
BYD says its subsidiary FinDreams Battery has supplied the Blade Battery for EV models of mainstream brands at home and abroad.
The company’s 2021 Tang EV, Qin PLUS EV, Song PLUS EV, and 2021 e2, will all equipped with Blade Batteries.
BYD says one of the biggest problems currently hindering the development of the EV market is the combustion and explosion of batteries. As the number of EVs on the road increases substantially the risk of battery safety accidents will rise accordingly, which makes power battery safety of paramount importance.
The BYD Han, the first model equipped with the Blade Battery, has sold more than 10,000 units each month consecutively since its launch in July 2020. This has a range of 600km using the additional capacity of the blade battery technology.
The test results under such extremely harsh test conditions are sufficient to prove the superior performance of the Blade Battery in terms of safety and strength.
