1. A method for testing an electrochemical battery, the method comprising:

  • generating a response by applying an excitation waveform to an electrochemical battery being tested while maintaining a magnitude of the excitation waveform small enough that a relationship between the response and the excitation waveform is substantially linear;

    monitoring the response;

    based upon values of the response during a period which does not exceed one cycle of the excitation waveform, determining a relationship between phase and amplitude of the excitation waveform and phase and amplitude of the response.
