Customer Training: Provide systematic training for customers' engineers and technical personnel on battery characteristics, integration specifications, usage precautions, and maintenance procedures.
On-site Support: Dispatch engineers for on-site technical guidance during the integration of battery modules/packs into the customer's production line, ensuring the process meets requirements and avoiding issues caused by improper operation.
Remote Diagnostics: Remotely monitor battery state of health (SOH) and safety status via data transmitted back by the Battery Management System (BMS), providing early warnings and preliminary diagnosis of potential failures.

Failure Analysis (FA): This is a core technical aspect of after-sales service. Conducts the following on returned defective cells or modules:
Visual Inspection
Electrical Performance Testing (capacity, internal resistance, self-discharge, etc.)
Root Cause Analysis (RCA): Based on FA results, trace back to potential links in the production process (e.g., material batches, coating, stacking, encapsulation, formation) to identify the root cause of the problem.
Corrective and Preventive Actions (CAPA): Feed analysis results back to the company's R&D and production departments to improve design and processes at the source, preventing problem recurrence.

Establish an efficient spare parts inventory to ensure timely provision of qualified cells or modules when customers need replacements.
Manage the logistics chain with customers, including the return of defective products and shipment of good products, maintaining thorough traceability records.

Provide clear warranty policies (e.g., duration, cycle count, capacity retention rate) according to contract terms.
Track the performance of batteries throughout their entire lifecycle on the customer side, providing data support for product iteration and new product development.
