Who this is for: Battery pack makers who purchase cells from 3rd party suppliers
PROBLEM: Battery cells must be tested for quality before being integrated into modules or packs. 100% coverage of incoming cells is often unfeasible, exposing pack makers to warranty risk.
SOLUTION: AccelaGrade Cell
About incoming cell QC
Battery cell quality has improved enormously over the last decade but there is still an urgent need for pack integrators to run quality control checks on purchased cells. Opaque supply chains, undetected material impurities, and simple bad luck can all lead to cell failures. Pack manufacturers are responsible for their own warranties to end-users and cannot afford to allow “bad apples to spoil the barrel”.
Today, most incoming cell QC begins with cell grading, followed by sampled batch capacity testing with cyclers, and then finally by OCV and ACIR sorting. Because cyclers take several hours to complete their tests, it is simply not feasible to test every cell. It would be better to achieve 100% QC coverage but this is often impossible given the economics of time, throughput, and the cost of power.
AccelaGrade, by Pulsenics, radically alters the economics of incoming cell QC. Our rapid, thorough, and affordable solution enables total QC coverage of incoming cells without expensive facility upgrades.
The AccelaGrade Difference
PERFORMANCE
Up to 19x faster than cyclers!
AccelaGrade can grade a battery cell in less than 30 minutes with up to 128 cells simultaneously. AccelaGrade™ Cell is a fully integrated battery testing and grading solution that cycles and grades cells using capacity and impedance measurements. It features robust temperature sensing and a patented cell balancing mechanism to ensure accurate, repeatable results.
AccelaGrade rapidly integrates data from:
- Partial cycling
- Temperature measurements
- Electrochemical impedance spectroscopy (EIS)
PRICE
AccelaGrade has the among the lowest costs per cell of any solution. Because it completes a grade much faster than a cycler, it saves on both labor hours and energy costs per unit. AccelaGrade’s modular architecture also does not require electrical upgrades in most scenarios.
Compared to cyclers, AccelaGrade:
- Delivers lower cost of quality.
- Uses a fraction of the electricity per cell.
Cyclers can’t match AccelaGrade’s throughput enablement
Your QC team works hard to produce great results, but legacy technologies prevent them from achieving 100% coverage of incoming cells. Why not enable your team to do that work faster, cheaper, and more thoroughly? Contact a Pulsenics consultant today.
