SEA
Sustainable Experience ArchitectureGeely's scalable EV architecture, from the compact EX30 to the Zeekr 7X and 7GT. One Chinese parent platform behind European brands, in several size variants: the first branch on 400V, the SEA3 branch on 800V. LFP on the entry versions, NMC on the larger packs — although on the 800V models it is precisely that LFP entry model that is the fastest charger of the range.
SEA is the EV platform of Geely Group, in production since 2021, with a 400V → 800V architecture. The SEA platform carries 8 models from 4 brands. The WLTP range of the current variants on SEA runs from 310 to 655 km.
Pick the car first, then the version — chemistry, battery and drive differ per version.
