Online broadband electrochemical impedance spectroscopy within direct power control of a neutral point clamped inverter
Online broadband electrochemical impedance spectroscopy within direct power control of a neutral point clamped inverter
This article proposes a new method for online electrochemical impedance spectroscopy (EIS) of batteries using a modified direct power controlled (DPC) grid-connected three-phase neutral point clamped (NPC) inverter. The method stimulates the battery by applying a pseudo-random binary sequence (PRBS) EIS signal to the dc link-capacitor voltage balancing control loop of the inverter. The proposed approach has been verified using a grid-connected NPC inverter model in MATLAB/Simulink. The method enables online battery diagnosis and management without the need for ancillary electronic circuits.

Abstract
This article proposes a new method for online electrochemical impedance spectroscopy (EIS) of batteries using a modified direct power controlled (DPC) grid-connected three-phase neutral point clamped (NPC) inverter. The method stimulates the battery by applying a pseudo-random binary sequence (PRBS) EIS signal to the dc link-capacitor voltage balancing control loop of the inverter. The proposed approach has been verified using a grid-connected NPC inverter model in MATLAB/Simulink. The method enables online battery diagnosis and management without the need for ancillary electronic circuits.
