On November 13, CATL unveiled the "Chocolate Battery Butler," a full-lifecycle battery visualization and detection system that creates a one-stop service platform anyone can understand, offering one-click peace of mind. The system supports 53 onboard self-checks and 66 in-depth inspections at battery swap stations, tackling the long-standing pain point of opaque power battery conditions. It enables full-process visibility, testability, controllability, and fallback assurance for batteries, and commits to lifetime monitoring, lifetime warranty, and lifetime free repair and replacement for batteries in the network. Under the plan, by 2027, Chocolate battery swapping will have cumulatively built 6,000 swap stations across 297 cities nationwide, essentially achieving full coverage of prefecture-level cities and municipalities directly under the central government in mainland China.
