Issues

An EV is a vehicle with a drive battery. Accurate prediction of battery capacity Q [Ah] in a very short time has been a long-standing technical challenge

For example, on-board batteries are not included in the valuation of used car purchases and are not fairly assessed in vehicle inspection at the dealer.
Battery technology is of great interest because of the huge market for EVs. Typical capacity is：40〜100kWh for BEV, 14kWh for PHEV, 1〜2kWh for HEV, and 400kWh for Energy Storage Station.
1. The most expensive replacement part in an xEV is the battery.
  • Vehicle life and battery life are unmatched.
  • In the case of HEVs, the average vehicle life is 11-17 years, whereas the life of a new battery is 5-8 years
2. All batteries degrade, but not to the same degree. Even when used in the same battery pack, the degree of degradation can vary.
  • The most degraded cell/module dominates the performance of the entire pack. This is because they are connected in series.
  • To get an accurate capacity of  the battery, you have to spend a long time. This is called a “Capacity Testing“.
3. There are several key factors on how to maximise the profit  generated from the aftermarket battery business.
1
Profitability
High prediction accuracy (preferably, at 95.5% = 2σ).
2
Investment amount
Short preparation time for introduction, affordable measurement equipments available, and no high level of expertise required.
3
Operational cost
Short measurement times, simple operation, and immediate results.
4
Measurability
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.
5.  We believe that our new technological approach will enable many customer to enjoy unparalleled benefits.
