We need public implementations of the features from Paulson et al., Table 1

Implement the following features

  • Median current, charge and discharge
  • Average voltage, charge and discharge
  • Cumulative capacity, charge and discharge
  • Cumulative energy, charge and discharge
  • Coulombic efficiency
  • Energy efficiency
  • Median current normalized by the lifetime median current, charge and discharge
  • Capacity as a fraction of initial capacity
  • Time charging and time discharging
  • Time at constant current, charge and discharge
  • Time at constant voltage, charge and discharge
  • Ratio between time at constant current and constant voltage, charge and discharge
  • Time interval during equal voltage change (3.5-4.0V), charge [Need @npaulson clarification]
  • Voltage at start and end of charge and discharge
  • Voltage at a certain state of charge, charge and discharge
  • Derivative of voltage wrt time at a certain state of charge, charge and discharge
  • Voltage change between start of cycle and certain time, charge and discharge
  • Open circuit voltage at a certain state of charge [Requires ECM fitter]
  • Resistance at a specific state of charge [Requires ECM fitter]
  • SOC at a specified voltage
  • Location of each peak in the dQdV curve, charge and discharge [Requires peak detection]
  • Magnitude of each peak in the dQdV curve, charge and discharge [Requires peak detection]
  • Area under each peak in the dQdV curve, charge and discharge [Requires peak detection]
  • Location of each valley in the dQdV curve, charge and discharge [Requires peak detection]
  • Magnitude of each valley in the dQdV curve, charge and discharge [Requires peak detection]
  • Location of each peak in the dVdQ curve, charge and discharge [Requires peak detection]
  • Magnitude of each peak in the dVdQ curve, charge and discharge [Requires peak detection]
  • Location of each valley in the dVdQ curve, charge and discharge [Requires peak detection]
  • Magnitude of each valley in the dVdq curve, charge and discharge [Requires peak detection]
  • Statistics of the different in rate of SOC vs voltage distribution between changes, charge and discharge
  • Change in SOH at a function of cycle

then

  • Create an example on how to compute the features

Added capacity-related features in #55 , though we can improve them #58
