We have started to build an HPC network to achieve a superior charging experience. As of December 31, 2024, we had built 1,727 super charging stations in operation equipped with 9,100 charging stalls in China. 
We currently offer a five-year or 100,000-kilometer limited warranty for new vehicles, and an eight-year or 160,000-kilometer limited warranty for battery packs, electric motors, electric motor controllers, and air springs. We also provide owners of our vehicles free roadside assistance during the warranty coverage 24 hours a day, seven days a week. 
We offer a suite of value-added services to serve our users’ needs and keep them engaged, such as paid membership, ancillary installation and connection services, and auto finance facilitation.
Manufacturing, Supply Chain, and Quality Control 
Manufacturing
We are listed in the catalog of vehicle manufacturers of the MIIT and we currently manufacture our vehicles in our Changzhou and Beijing manufacturing bases. A manufacturing base consists of four workshops, stamping, welding, painting, and assembly, and an office building. Our production volume can be further expanded with our increased efficiency and technological capabilities.
The production in our factory is highly automated to ensure precision, consistency, and efficiency. We use linear seven-axis robots for our stamping line, which is capable of switching tooling with the press of a button and mixed production of steel and aluminum parts. In the stamping workshop, the high-speed flexible manufacturing line first produces large body panels before fully-automated, quality inspection blue-ray scanning performs 100% of the dimensional inspections on them. In the welding workshop, we achieve 100% automation for all welding spots. In the painting workshop, we have fully automated the painting process by utilizing painting robots to ensure consistency of coatings on the vehicle bodies.
We remain committed to operating our own manufacturing facilities, with our green intelligent manufacturing bases in Changzhou and Beijing, China. By adopting highly automated, intelligent, and digitalized production lines with a large amount of cutting-edge manufacturing processes, we created an efficient and controllable intelligent manufacturing system. Leveraging our proprietary intelligent platforms such as the stamping digitalization system, Lianshan quality monitoring and early warning platform, and Li-MOS manufacturing management system, we built an intelligent manufacturing super brain to connect all assembly data and process flows, achieving end-to-end closed-loop management throughout all processes of each business. We also used vision sensors
