e-Platform 3.0
+ 3.0 Evo (800V)BYD's vertically integrated EV base with the Blade battery: cobalt-free LFP cells in a pack that, on the Seal and Sealion 7, is executed as a load-bearing chassis part (cell-to-body). The platform carries both 400V and 800V models, from the urban Dolphin Surf to the Sealion 7 on the Evo extension — charging power differs accordingly per version.
e-Platform 3.0 is the EV platform of BYD, in production since 2021, with a 400V · 800V (Seal, Sealion 7) architecture. The e-Platform 3.0 platform carries 7 models from 1 brand. The WLTP range of the current variants on e-Platform 3.0 runs from 220 to 570 km.
