Pouch Power Battery Welding Sealing Line

HY delivers industry-leading 12PPM pouch battery welding and packaging lines engineered for high-volume EV and energy storage manufacturing. Our automated production systems achieve consistent throughput of 12 units per minute with precision laser welding at ±0.1mm tolerance, ensuring every module meets strict automotive-grade quality standards. The modular design allows seamless scalability, enabling manufacturers to ramp up production without sacrificing yield or reliability. Integrated MES systems provide real-time production monitoring, traceability, and data analytics for continuous process optimization. Backed by over a decade of automation expertise, HY has deployed dozens of high-capacity battery lines worldwide, helping clients reduce labor costs by up to 60% while boosting overall equipment effectiveness (OEE) to over 95%. Whether you need VDA-standard or HEV-specific configurations, our high-capacity solutions deliver the speed and precision demanded by today’s fast-growing lithium battery industry.

HY’s precision laser welding technology sets a new benchmark for pouch battery module assembly. Our systems employ advanced fiber laser sources with real-time power feedback and visual positioning systems, achieving welding accuracy within ±0.1mm across tab welding, busbar connections, and structural component joining. The non-contact welding process minimizes thermal distortion, preserves cell integrity, and produces consistent, high-strength joints essential for battery performance and safety. Each welding station integrates pre- and post-welding inspection — including short-circuit testing, weld quality verification, and dimensional checks — ensuring zero defects reach downstream processes. Research in advanced manufacturing confirms that laser welding delivers 30% higher joint reliability than traditional resistance welding methods. HY’s precision welding solutions are trusted by leading battery manufacturers for VDA, HEV, and energy storage module production lines worldwide.

HY’s VDA-standard pouch battery welding and packaging lines are purpose-built for the European automotive market’s stringent requirements. VDA (Verband der Automobilindustrie) standards demand precise dimensional control, consistent electrical performance, and rigorous traceability — all of which our lines deliver through advanced automation and integrated quality systems. The 12PPM VDA line handles cell feeding, plasma cleaning, adhesive application, module stacking, tab laser welding, busbar assembly, insulation testing, and end-of-line (EOL) verification in a single continuous flow. Every module carries a unique digital identity with complete process data, enabling full traceability from raw cell to finished product. With VDA-format batteries powering a growing share of European EVs, partnering with HY ensures your production meets the highest industry benchmarks for quality, safety, and regulatory compliance while maintaining competitive cost per unit.

Quality is non-negotiable in battery manufacturing, and HY’s multi-stage inspection systems leave nothing to chance. Our pouch battery lines incorporate comprehensive quality checkpoints at every critical stage: incoming cell voltage and internal resistance testing, post-welding short-circuit verification, weld seam visual inspection with AI-powered defect detection, insulation and withstand voltage testing, dimensional accuracy verification, and final EOL performance testing. Each inspection station uses high-resolution cameras, precision sensors, and advanced algorithms to catch even the slightest deviation from specifications. Statistical process control (SPC) systems analyze inspection data in real time, identifying trends and triggering automatic adjustments before defects occur. Industry studies show that multi-stage in-line inspection reduces field failure rates by 75% compared to end-of-line-only testing. HY’s quality-first approach ensures that every battery module leaving your factory meets the highest safety and performance standards.
