Industry sources told 36Kr that Sunwoda’s Gen 3 LFP cells support up to 3C charging rates. Current CATL LFP packs in Tesla vehicles charge at approximately 1.5C. If the 3C claim is accurate, Sunwoda-equipped vehicles could accept roughly twice the charging speed of CATL LFP packs — a material advantage for fleet operators relying on rapid turnaround. However, no independent test data exists to validate this claim. Expected resolution: 2027 — post domestic deployment and independent testing by Dongchedi, autohome, or equivalent. Status: OPEN.
Tesla purchases cells only from Sunwoda and self-assembles modules and packs. This is structurally different from the CATL relationship where Tesla procures complete modules. Cell-level thermal safety margins for LFP are well-documented (~270C thermal runaway onset), but pack-level thermal runaway propagation test results for Tesla’s Sunwoda-cell packs have not been published. Tesla’s pack assembly quality for Sunwoda cells is unverified by any third party. Expected resolution: Unknown — requires independent pack-level abuse testing. Status: OPEN.
