Abstract
A system for measuring a complex impedance associated with an arrangement of battery or fuel cells in an energy storage system may include a controller, a current measurement device, and voltage measurement devices. The current measurement device may be shared by the cells for measuring a test current provided to the cells. The voltage measurement devices may be respectively coupled across corresponding cells. The controller, the current measurement device, and the voltage measurement devices may be coupled together using a DC isolated bus. The controller may determine a respective complex impedance of corresponding groups of the cells using a complex voltage measured by a respective voltage measurement device coupled across a corresponding group of the cells and a complex current measured by the complex current measurement device. The controller may be configured to compensate for an asynchrony between particular ones of the current measurement device and the voltage measurement devices via the DC isolated bus.
