Nex GenPower's Product Development Workflow and Flowchart

I. General Principles for the R&D Work Process

Nexgenpower's product development workflow is centered on GaN (gallium nitride) technology, driven by innovation implementation, and aimed at compliant mass production. It covers the entire lifecycle from market research to product iteration, focusing specifically on power adapters across multiple power ratings (30W,45W,65W,100W, and 140W). Adhering to the principles of closed-loop control, stringent standards, and rapid iteration, the total development cycle spans 6–12 months, ensuring products comply with global safety standards, meet diverse application requirements, and establish a distinctive competitive edge.

Core Focus: Centered on GaN (gallium nitride), smart fast charging, and miniaturized lightweight design as key innovations, we reject standardized solutions and develop next-generation power adapters that are "highly efficient, safe, portable, and compliant," suitable for diverse applications including consumer electronics, industrial control systems, energy storage, and automotive environments.

Phase 4: Sample Production and Comprehensive Validation Testing (Validation Period | 2 months)

Core Objective: To validate the feasibility of the R&D design, ensure that the product meets requirements for innovation performance, safety performance, and compatibility performance, and complete prototype finalization.

• Core tasks: Complete three rounds of sample development (hand-made prototype → PCB prototype → engineering prototype); conduct comprehensive testing (electrical performance, thermal performance, safety and reliability, EMC electromagnetic compatibility, protocol compatibility, and specialized innovation tests); address identified issues through optimization, and finalize the prototype design.

• Deliverables: 3–5 engineering finalized prototypes (EVTs), the Prototype Test Report, the Innovation Performance Verification Report, and the Problem Correction Report.

Phase 5: Compliance Certification and Supply Chain Implementation (Compliance Period | 1.5 months)

Key objectives: Achieve global safety certification, establish a stable supply chain, and ensure product compliance for mass production.

• Core responsibilities: Obtaining global safety certifications (domestic CCC, international CE-LVD/EMC, UL/FCC, etc.); selecting qualified suppliers for critical components such as GaN chips and transformers; developing mass-production molds and conducting trial molding; formulating procurement plans and designing production line fixtures and jigs.

• Deliverables: complete set of safety compliance certifications, mass-production BOM list, qualified supplier directory, mass-production mold documentation, procurement plan, and tooling/fixing design drawings.

Phase 6: Pilot Production Ramp-up and Mass Production Delivery (Mass Production Phase | 1 month)

Core Objective: To validate the feasibility of mass production processes, achieve scalable manufacturing, and ensure stable product quality and timely delivery.

• Core Task: Conduct small-batch pilot production (500–2000 units) to validate production line processes, assembly efficiency, and product yield; optimize mass-production processes and firmware burning procedures; initiate large-scale production once yield reaches ≥98%, implement full factory inspection standards, and complete batch deliveries.

• Deliverables: DVT trial production report, PVT mass production qualification report, Nanjin Power's factory-wide inspection standard documents, mass production warehousing records, and first batch shipment certificates.

Phase 7: Market Launch Iteration and Technical Pre-research (Duration | Long-term)

Core objectives: Collect market feedback, optimize product iteration, develop next-generation technologies, and maintain R&D competitiveness.

• Core Tasks: Support product launch campaigns by collecting user feedback and market failure data; initiate iterative innovation for versions V2/V3; establish intellectual property portfolios (including invention patents and utility model patents); conduct preliminary research on next-generation technologies such as SiC (silicon carbide), ultra-high-power solutions, and automotive power systems.

IV. Core Requirements and Key Considerations for the R&D Process

• Deliverables reviews must be completed at each stage; failure to pass the review prevents progression to the next stage, ensuring controllable R&D quality.

• The verification testing phase must strictly adhere to Nanjing Institute's stringent standards, which exceed national industry benchmarks, with particular emphasis on evaluating the performance, thermal management, and safety protection of GaN devices.

• When integrating into the supply chain, prioritize suppliers of critical components with safety certification to ensure compliance and stability of mass-produced products.

• Implement comprehensive patent strategy across the entire process to establish robust brand technological barriers and mitigate infringement risks.

• Establish a rapid iteration mechanism to promptly optimize product design based on market feedback and technological advancements, thereby maintaining industry competitiveness.
