A high energy density module solution independently developed for cylindrical cells, with systematic protection designed across active and passive safety and at four levels: cell, module, system and vehicle. After ten years of iterative R&D and over 10,000 cell explosion tests, the pack stays fire-free after a single cell explosion — the first industrialized zero-thermal-runaway safety technology for high energy density NMC batteries in China, already fitted on JAC new energy models.

Model: BEST (Bipolar Encapsulated STructure); Compatible cells: cylindrical (NMC); Thermal runaway behavior: pack remains fire-free with zero heat propagation after single-cell explosion; Validation: 10 years of iteration, 10,000+ cell explosion tests; Core advantages: zero thermal propagation/efficient packing/all-weather availability; Pack thermal management: liquid cooling

• High energy density NMC passenger vehicles
