A battery pack manufacturer required an automated solution to eliminate a critical production bottleneck in battery cell inspection and testing. The manual inspection and testing process consumed 47% of total battery pack build time, creating significant efficiency constraints and introducing potential for human error in data collection. The client needed a fully automated system capable of integrating battery testing equipment, which traditionally operates independently, with robotic handling and machine control systems to create a seamless, high-throughput testing operation.

CAPABILITIES APPLIED
The manufacturer faced multiple interconnected challenges in scaling battery production:
Labor-Intensive Bottleneck: Manual cell inspection and electrical testing represented nearly half of the total assembly time, limiting production capacity and increasing labor costs.
Equipment Integration Complexity: Battery testing equipment could not interface with standard robotics and machine control systems, requiring a novel approach to system orchestration and communication protocols.
Data Management and Quality Control: Manual data entry created opportunities for errors while making traceability and real-time quality monitoring difficult to maintain across production batches.
Production Scalability: The existing process lacked the throughput capacity needed to meet growing demand without proportional increases in labor and floor space.
Re:Build delivered a fully automated, Industry 4.0-enabled battery cell test station that transformed the manufacturer’s inspection and testing workflow.
The solution integrated robotic material handling with vision inspection systems and electrical testing equipment through an edge computing platform. This enabled automated orchestration of cell movement, visual inspection (top and bottom), electrical testing (voltage and internal resistance), and data logging—all without operator intervention beyond initial cell loading.
The edge computer automatically configured and executed each electrical test based on cell specifications, while AI-driven vision systems performed defect detection. All test data, inspection images, and manufacturer specifications were consolidated into a centralized database, creating complete traceability for every cell processed.
The automated system reduced total battery cell inspection and testing time by 80%, decreasing overall battery pack assembly time from 170 minutes to 90 minutes. Manual data entry errors were eliminated through full automation of the data collection process. The modular system architecture supports future expansion to accommodate increased production volumes.
Quality and consistency improved through standardized inspection protocols and real-time monitoring, while the turnkey solution integrated seamlessly into the existing production environment. The manufacturer gained a scalable, efficient testing infrastructure that positioned the operation for long-term growth while reducing labor dependency and operating costs.
