Battery Degradation Is Inevitable — Accurate Diagnosis Is Still a Challenge

All batteries degrade over time, unevenly and unpredictably. Yet there is still no simple, fast, and accurate method for measuring true battery capacity in real-world environments.

Conventional diagnostic methods often require long testing times, controlled environments, or complex electrochemical analysis. Once current is applied, the internal state of the battery immediately begins to change, reducing prediction accuracy during the measurement itself.

As a result, millions of automotive and xEV batteries are replaced, reused, or discarded without reliable visibility into their actual health condition.

To get an accurate capacity of  the battery, you have to spend a long time. This is called a “Capacity Testing“.

Battery technology has advanced rapidly, but testing technologies are still stuck in the past.  We believe even the best battery is useless without performance monitoring.

１. Onboard diagnostics： Still at the innovator stage

  • Until now, no practical technology existed.
  • It’s not part of vehicle inspections, and no battery health information is disclosed for resale value.
  • Consumers hesitate to buy a used xEV because of a lack of transparency

2. Off-board diagnosis： Battery remanufacturing & Repurposing market

  • You can get an accurate capacity measurement if you spend a full day — but when time is short, accuracy drops dramatically.
  •  With millions of batteries in the field, speed and accuracy are a trade-off.

3. There are several key factors in how to maximise the profit generated from the aftermarket battery business.

1
Profitability
High prediction accuracy (preferably, up to 95.5% = 2σ).
2
Low CAPEX
Short preparation time for introduction, affordable measurement equipment available, and no high level of expertise required.
3
Productivity
Short measurement times, simple operation, and immediate results.
4
Traceability & Visibility
Real-time monitoring is possible, and aware of changes.
5
Trustworthiness and  reliability
Customer services are available, businesses can operate non-stop, and with increased productivity and profitability.
