Hedian Technology always takes customer needs as the core and builds a full-cycle and professional customer service system. Pre-sales Stage The professional technical team provides one-on-one consulting services. By combining with customers' application scenarios (such as energy storage power stations and new energy vehicles), we deeply analyze their needs, customize sodium-ion battery cathode material and cell product solutions, and assist in completing model selection and planning. In-sales Stage We strictly control the production, quality inspection, and logistics processes, provide real-time progress feedback to ensure efficient product delivery, and offer installation and debugging guidance as well as technical training to guarantee the smooth operation of equipment. After-sales Stage A 7×24-hour customer service response mechanism is always on standby to quickly resolve issues during use; regular follow-ups are conducted to collect feedback for continuous optimization of products and services; for technical challenges, expert teams provide remote support or on-site services to ensure worry-free use for customers.
