TREE NEWS update: CATL unveiled its “Chocolate Battery Manager” on Nov. 13, a battery visualization and full-lifecycle inspection system offering 53 on-vehicle self-checks and 66 deep checks at swap stations. The company pledged lifetime monitoring, warranty, and free repair or replacement for batteries in its network. CATL plans to have 6,000 Chocolate battery-swap stations built by 2027, covering 297 Chinese cities.
CATL Launches Chocolate Battery Manager, Targets 6,000 Swap Stations by 2027
CATL is positioning battery diagnostics and warranty coverage as the differentiator for its swap network, not just station count — a lifecycle guarantee is a heavier commitment than hardware rollout, and it shifts competitive pressure toward whoever can prove battery health at scale. The pledge effectively underwrites used-battery value inside CATL's ecosystem, which matters for fleet operators and anyone holding swap-network assets. Whether the 6,000-station target and the lifetime service promise stay aligned as buildout accelerates is the open question.
