In response to an inner supply cited by CarNewsChina, BYD is creating two variants of its new blade battery. The primary variant contains a brief blade format with an vitality density of 160 Wh/kg, a cost charge of 8C, and a most discharge charge of 16C. The longer blade format will provide an vitality density of as much as 210 Wh/kg, with a cost charge of 3C and a discharge charge of 8C.
The Blade battery, launched in 2020, is a product of BYD’s in-house improvement. The identify comes from the battery’s distinctive design—elongated cells that resemble a sword blade. These cells are put in in battery packs at proper angles to the automobile’s path of journey. BYD employs varied configurations, using each cell-to-pack and cell-to-body designs in its electrical autos. All variations share lithium iron phosphate cell chemistry, with the present blade battery reaching an vitality density of roughly 150 Wh/kg.
As BYD has not up to date its battery know-how lately, the launch of the second technology is extremely anticipated. If the insider data is correct, BYD will introduce batteries that includes both longer or shorter “sword blade cells” sooner or later. The “C” worth signifies the ratio of battery dimension to charging and discharging capability; as an example, at 1C, an 80 kWh battery could be charged with a most of 80 kW, whereas at 8C, it may doubtlessly cost at as much as 640 kW. Nevertheless, it stays unclear what vitality capability the brand new BYD battery may have.
Additional particulars from CarNewsChina recommend that the fast-charging battery variant with the shorter blades and an vitality density of 160 Wh/kg shall be priced equally to or barely greater than the present technology. This pricing is attributed to the challenges in scaling manufacturing for this model and BYD’s restricted affect over its suppliers. In distinction, the extra energy-efficient battery variant is anticipated to value 15 p.c lower than the present technology. Rumors point out that the brand new blade battery shall be utilized in BYD’s U7 sedan from its Yangwang subsidiary, amongst different functions.
Within the aggressive Chinese language battery market, BYD has captured a 24.4 p.c market share within the present yr, based mostly on knowledge from the China EV DataTracker, after finishing three out of 4 quarters. BYD has put in 101 GWh of electrical automobile battery capability, marking a 19.4 p.c enhance in comparison with the identical interval final yr, primarily specializing in lithium iron phosphate (LFP) batteries. Compared, CATL instructions a 46 p.c market share in China, with an put in capability of 183.02 GWh, which represents a forty five p.c year-over-year development, pushed primarily by LFP batteries (+60%) and to a lesser extent by NMC batteries (+28%).
