Electrochemical cell diagnostic systems and methods are described. Examples include systems having a signal generator configured to apply a stimulus having a stimulus frequency to at least one electrochemical cell. The stimulus may be configured to excite at least one non-linear mode of the at least one electrochemical cell. Systems may include measurement circuitry configured to detect a response of the at least one electrochemical cell to the stimulus. The response may include a second or greater harmonic component. Systems may include a display device configured to display an indication of an internal state of the at least one electrochemical cell based, at least in part of the second or greater harmonic component of the response.
