3-2、Phase Deliverables: 1. Operational Functional Prototypes; 2. Prototype Lab Testing & Validation Report; 3. Test-Driven Design Optimization Recommendations (if applicable).

4、 Certification & Compliance (if applicable):

4-1、Scope of Work: Compile sample-stage safety and insulation metrics, prepare regulatory filing dossiers, and execute dedicated product certification testing.

4-2、Phase Deliverables: Official Product Certification Credentials (e.g., UL 9540, UL 2580, IEC 62619, UN 38.3, etc.)

Phase 4: Mass Production Stage

1、Scope of Work:

1-1、Solidify mass production processes, compile Standard Operating Procedures (SOP), and lock critical inspection parameters;

1-2、 Activate supply chain buffer mechanisms for bulk core component sourcing to enforce rigorous Incoming Quality Control (IQC);

1-3、 Initiate flexible production line manufacturing, utilizing MES systems for digitalized, real-time In-Process Quality Control (IPQC);

1-4、Implement advanced cell grouping algorithms based on internal resistance and static/dynamic voltage sorting to optimize product consistency;

1-5、Continuously balance production line efficiency using live manufacturing data to compress non-standard system delivery lead times;

1-6、Establish OTA remote wireless firmware upgrade channels to provide project-based field and remote terminal operation support.

2、Phase Deliverables:

2-1、 Mass-Produced High-Consistency Battery Systems (fully verified via OQC protocols);

2-2、Official Outgoing Quality Control Reports (OQC Report);

2-3、Full-Lifecycle MES Digital Traceability Dossiers (component batch lineages, cell matching logs);

2-4、 User Operation, Functional Safety, and Maintenance Manuals.

Phase 5: Post-Sales & Operations Phase Description:

1、Commissioning & Acceptance Support: Provide remote or on-site field installation guidance, execute multi-system joint commissioning, activate the terminal deployment, and finalize the customer acceptance sign-off.

2、 Localized Operations Training: Deliver engineering-grade training sessions for client technical teams covering daily operations, functional safety troubleshooting, and hardware/software O&M practices.

3、 OTA Remote Lifelong Maintenance: Maintain an active OTA (Over-The-Air) firmware update channel to wirelessly deploy communication protocol calibrations and software optimizations, eliminating the massive logistics costs and timelines of cross-ocean hardware returns.

4、 Project-Based SLA Execution: Implement independent, project-specific Service Level Agreements (SLA) structured around specific application complexities, response window thresholds, and engineering hours for transparent, standalone billing.
