Questions about the testing process
- Can you propose a complete solution for our needs?
- We need to test and sort salvaged Li-Ion cells from EV battery packs
- Measurement of at least 10k cells / month, preferably 20k~40k. 8hrs operation /day, 5 days a week
- Scalability for more cells /month later by adding machines / personnel
- Low human operations needed. 1 operator would be great
- 18650 cells but we will eventually need to test 21700 cells. Easily switching cell size on the machines without buying new ones would be interesting
- Cell tab cleaning
- What solution is usually employed when salvaging cells?
- Is there a machine for removing nickel strip chips from cells salvaged from spot welded battery packs? Sanding?
- Only manual operation with cutters?
- Can you propose an AOI machine for checking both cell ends making sure they have been correctly removed?
- Logistics
- Cell feeding
- Magnetic cell pick up tool?
- Blue boxes? ⇒ IR-V tester feeding and outputs
- For a given IR testing machine model, how many cells can fit in each output compartment?

Questions specific to capacity testing machines (256/512-channel)
- User manual / tutorial / video training? English software?
- Upon reception, do we need to calibrate each channel for precise voltage and current readings? Is it trustfully factory calibrated?
- Recommended cell sorting criteria? Every 100mAh ? 50?
- How to change between 18650 / 21700 cell sizes? Needs complete different machine? Can be changed manually?
- TOB : more details on :
- “A LED is mounted on each of the battery fixtures as an operational status display, and when the discharge is completed, it can be used to indicate battery capacity sorting.”
- Software features :
- “Arbitrary segmented battery capacity indication (up to 100 segments)”
- “Battery sorting function under various conditions (capacity, time, open circuit voltage, discharge platform, etc.)”
- How to retrieve cell data? .csv files?
