Recently, the first set of CIR (Cell in Room) battery system products of CALB Jiangsu Phase III was successfully launched. The CIR battery system products launched this time are designed to achieve the ultimate balance of energy and resources, energy and safety, with a high degree of integration between design and manufacturing. It is the first square true C2P mass-production product in the field, thanks to its truly simplified design - no end plates, no side plates, no ties, and extremely simplified manufacturing, with approximately 25% simpler processes and a 30% reduction in line occupancy. The CIR production line also applies high-precision grouping technology, high-speed and highly flexible welding process technology, and high-speed intelligent technology, which fully represents CALB's minimalist manufacturing, extreme manufacturing and intelligent manufacturing capabilities for the TWh era. Furthermore, with the application of CALB's first pulse self-heating technology, the product can achieve an industry-leading heating speed up to 3°C/min, which can better easily support the matching models in all weather conditions.
