en.Wedoany.com Reported - Hyundai Motor has developed a system that integrates the electric vehicle battery manufacturing process into a single step. This "High-Speed Integrated Battery Stacking System for Electric Vehicles" consolidates the existing seven battery processes into one, while enhancing battery pack stability. The system has been selected as a winner of the 27th IR52 Jang Young-shil Award for 2026.

With the expansion of the electric vehicle and hybrid vehicle markets, demand for faster and higher-quality battery processes has increased. However, traditional battery processes are less efficient due to numerous stages and complex structures. For example, manufacturing high-performance batteries requires stacking multiple cells, but previous processes involved separate transfer and stacking steps.

Hyundai Motor has recently succeeded in integrating the following processes into a single system: a warehouse system for stably storing large quantities of batteries, a logistics system for rapidly transferring batteries and making real-time corrections, and a stacking system for high-speed assembly of components.

According to Hyundai Motor's internal verification, the battery pack stacking speed is 38% faster than the existing process, and production efficiency has increased by 40%. Additionally, the alignment of battery cells is more precise, with the error margin reduced from 1 millimeter to 0.1 millimeters, approximately one-tenth of the previous level. With the consolidation of multiple processes, the system structure has also been simplified. In traditional processes, impact-resistant batteries could detach during the transfer stage, potentially causing fires, whereas the single-step manufacturing method can fundamentally reduce accident triggers.

Thanks to multi-stage standardization, investment efficiency in the future battery sector is expected to improve significantly. Manufacturing battery packs for other companies takes 2.5 seconds per set, while the system developed by Hyundai Motor can complete one set in 0.75 seconds. If processes are separated, a delay of about 7 seconds occurs between battery manufacturing steps, but the new system enables continuous manufacturing without delays.

Hyundai Motor began selling the system in October 2025, achieving sales of over 2.3 billion Korean won that year. By 2029, sales are expected to approach 160 billion Korean won. With growing global demand for advanced electric vehicle battery production lines, the system is well-positioned for both domestic sales and exports. All internal technologies of the system were independently developed by Hyundai Motor.

Batteries produced by this system will first be applied to Genesis models, with expansion to more models in the future. Park Jong-min, Principal Researcher at Hyundai Motor's Mechatronics Research Team, stated that this technology can improve the quality stability of battery processes, fundamentally reduce fire risks, contribute to the safety of people's daily lives and the quality of electric vehicles, and help build consumer trust in the quality of electric vehicles.
