The following characterisations are carried out at cell level:
- Charging and discharging behaviour at different C-rates
- Verification of the specified performance data
- Determination of the usable capacity
- Internal resistance measurementRac andRdc
- Electrochemical impedance spectroscopy
- Cyclic voltammetry
- Cycle tests
- Temperature behaviour
- Other measurements within the operating conditions
- Standard charging methods such as CCCV, energy-controlled or customised profiles
