A Complete Process from Requirement to Verified Prototype
Our sample development workflow helps energy storage buyers reduce uncertainty before mass production, with clear engineering checkpoints from concept review to sample confirmation.
Requirement Analysis
Define specifications, use cases, certification goals, and target quantity.
Engineering Evaluation
Evaluate cells, BMS, structure, thermal control, and feasibility.
Prototype Design
Confirm layout, housing, wiring, function, and assembly method.
Sample Testing
Test performance, protection, stability, reliability, and safety.
Sample Confirmation
Optimize through customer feedback and prepare mass production planning.
Step 1: Requirement Analysis
Our team collects detailed project requirements including voltage, capacity, application scenarios, certification needs, installation environment, and estimated quantity. This ensures the design concept aligns with customer expectations from the start.
Electrical Specs
Voltage, capacity, power output, cycle life, and charging requirements.
Application Scenario

Step 2 & 3: Engineering Evaluation & Prototype Design
Engineering evaluation includes cell selection, BMS configuration, thermal and structural design, and safety verification. Prototype design involves layout planning, electrical schematics, housing, and functionality testing to ensure the first sample reflects the final product expectations.
Engineering Evaluation
Cell selection, BMS strategy, protection logic, thermal pathway, structure feasibility, and certification risk review.
Prototype Design
Battery layout, electrical schematic, housing structure, connectors, functional requirements, and assembly route planning.
Step 4: Sample Testing
Each sample undergoes rigorous testing including charge/discharge performance, BMS function verification, aging test, and environmental simulation to guarantee performance, reliability, and safety before delivery.
Charge & Discharge Performance
Output stability, capacity validation, charging curve, discharge efficiency, and performance consistency.
BMS Function Verification
Protection logic, communication function, balancing, over-current, over-voltage, and temperature safeguards.
Aging & Cycle Test
Long-duration operation, repeated cycling, thermal observation, and sample reliability verification.
Environmental & Safety Simulation
Application compatibility, safety protection, environmental impact, and pre-delivery validation.
Testing Bench Visibility
Sample test results help confirm whether the prototype can meet real-world energy storage scenarios before entering mass production planning.

Step 5: Sample Confirmation
After testing, samples are reviewed together with the customer. Feedback is incorporated, adjustments are made, and the optimized sample is finalized, ready for mass production planning.
Customer Review
The customer checks appearance, function, installation compatibility, and sample performance.
Feedback Optimization
Engineering adjustments are made based on real feedback and project priorities.
Mass Production Planning
Confirmed samples provide the foundation for production route, quality plan, packaging, and delivery schedule.
