Requirements checklist

What to ask for when choosing software for eV component manufacturers.

A checklist built from how eV component manufacturers work, to print or save as a PDF and bring to any supplier meeting.

Share your requirements

What the software should cover

Tick each one that matters to your business.

  • Cell lots and grading
  • Module and pack build
  • Firmware and board records
  • End-of-line testing
  • Rework and defect codes
  • Variant, label and despatch control

Roles that need their own access

Who logs in, and what each person may see or change.

  • For plant managers
  • For stores
  • For line operators
  • For test and rework staff
  • For dispatch

Reports to ask for

Ask to see each one with your own sample data.

  • Packs built by variant and serial range
  • Cell lots by module, tray and pack
  • Hipot and balance failures by bay and shift
  • Rework causes by part and defect code
  • BMS firmware versions by pack serial
  • Storage charge of finished packs on the shelf
  • Field queries traced to a cell lot

Systems it may need to connect to

Note which ones you already run.

  • Email
  • WhatsApp
  • Grading machine file import
  • Accounting export

Questions for any vendor

Put these to every supplier you are comparing.

  • Can it trace a pack to its cells?
  • Does it stop mixed cell lots in a module?
  • Can firmware versions be tracked?
  • What about end-of-line tests?
  • Is it limited to battery packs?
  • Can grading machine files be imported?
  • What affects the cost?
  • Can we export serial histories?

Where the work usually breaks today

Circle the ones you recognise. They set the order of the project.

  • Cycler grading files sit on one PC
  • Weld and torque records carry no pack serial
  • BMS firmware versions rest on a note
  • End-of-line failures leave no defect trail
  • Variants multiply across one bench
