Laser Welding, Automation & Custom Programming

Precision laser welding solutions with automation and custom programming support for battery modules, pack assemblies, interconnect systems, and scalable assembly workflows.

Built for repeatable weld quality, automated assembly, and assembly-ready process control
Our Expertise

Advance Laser Welding Workflows with Automation, Process Control, and Custom Programming

Prime Energy's laser-welding services apply to approved external terminals, tabs, busbars, interconnects and pack-level components. Prime Energy does not open sealed cells or modify their internal chemistry.

We help engineering teams and assembly programs develop laser welding processes that go beyond the weld itself. That includes automated movement, part positioning, fixture coordination, weld path logic, parameter control, and custom programming that supports repeatable battery assembly.

From tab welding and busbar joining to module interconnects and pilot assembly workflows, our approach focuses on precision, consistency, throughput, and assembly-aware integration between welding hardware, tooling, and programmable automation systems.

Standards Customers Often Prepare For

The programs below are common lithium battery certification and test pathways. Prime Energy can help customers prepare documentation, test readiness, and pack design decisions aligned to these standards. Listing these standards does not mean Prime Energy or every completed battery assembly currently holds these certifications.

  • UL 1973 — For lithium battery packs and systems used in stationary energy storage and motive auxiliary power applications.
  • UL 2580 — For lithium battery packs and modules used in electric vehicle applications.
  • UL 2271 — For lithium batteries used in light electric vehicle applications such as smaller mobility platforms and support vehicles.
  • IEC 62133-2 — For portable sealed secondary lithium cells and batteries used in portable applications.
  • IEC 62619 — For secondary lithium cells and batteries used in industrial applications, including many larger pack and stationary use cases.
  • IECEE CB Scheme — A global certification pathway that helps support international acceptance of test reports and certificates for applicable IEC battery standards.
  • UL 9540 — System-level listing path for complete energy storage systems and equipment, often relevant when a battery pack is part of a larger ESS.
  • UL 9540A — Fire test method commonly used to evaluate thermal runaway fire propagation behavior in battery energy storage systems.
  • UN 38.3 — Transport testing required for shipping lithium cells and batteries; this is a transportation compliance requirement rather than a product safety listing.
