ESS line buyer guides

What a line costs, how capacity is calculated, how to choose the machines: the questions that come up when planning an ESS module and PACK line, answered in engineering terms.

  1. 01How much does an ESS module and PACK line cost? Investment, price ranges and lead timesAn ESS module and PACK line runs from under a million to several million US dollars, depending on scale, automation and what the quote includes. Typical industry ranges for how the price is built, how to weigh full versus semi-automation, what quotes include, how long delivery takes, and how to make quotes comparable.
  2. 02How to choose a cell sorting machine: OCV and IR grading for large ESS cellsStorage cells have only 0.15–0.25 mΩ of internal resistance, so the sorter's accuracy, matching rules and takt decide how consistent your modules are. What a sorter measures, how to read accuracy specs, how to set bins and matching, how to match line takt, and how to prove at acceptance that it measures right.
  3. 03How to convert line takt (PPM) to annual GWh: formula and quick tablesOne formula turns a line's takt (PPM) into annual capacity (GWh) — cell energy × takt × run time × OEE. Quick tables for 280, 314, 587 and 628 Ah cells, how to work back to the takt you need, and five reasons real output falls short.
  4. 04Moving from 314 Ah to 500 Ah-plus cells: what changes on a module and PACK line587, 588 and 628 Ah storage cells are ramping fast. Cells twice as heavy with nearly twice the energy change infeed, stacking, welding and test. Station by station, what to change, when to retrofit or build new, and what a line for both 314 Ah and large cells needs.
  5. 05Busbar laser welding for ESS modules: choosing the laser, setting parameters, proving qualityAluminium busbars on prismatic storage cells are almost always laser welded. Laser and head selection, key parameters and the process window, cleaning and clamping before the weld, in-process monitoring and factory acceptance — the engineering essentials in one guide.
  6. 06EOL and leak testing for ESS modules and PACKs: what to test, which parameters, how to judge a passThe last gate before modules and PACKs leave the line. Module and PACK EOL test items with typical parameters, which voltages insulation and withstand tests use, how cooling plates and full packs are leak-tested and judged, how test takt fits the line, and which items national standards treat as type tests versus factory inspection.

Supply-chain solutions

An ESS line draws on dozens of equipment and component suppliers. Drawing on the full ESS equipment supply chain, we source complete lines or single machines to your requirements, under one technical agreement, one delivery plan and one service contact.

  • Turnkey lines: module and PACK, fully or semi-automatic
  • Single machines: sorting, stacking, welding, dispensing, EOL, leak test
  • Key components: lasers and scanners, test instruments, robots, vision
  • Logistics and software: AGVs and conveyors, MES and traceability

Lines, machines and key components —
one point of contact.

Beyond our own line, we run supply-chain solutions for ESS production: sorting, welding, test, logistics and MES equipment and key components, matched to your cell, capacity and budget, delivered and commissioned as one project.
