Abstract
A system for assessing the accuracy of an electrochemical cell voltage measurement includes a cell discharge circuit electrically coupled to at least one electrochemical cell and configured to partially discharge the at least one cell when the cell discharge circuit is activated, and a cell measurement circuit electrically coupled to the at least one cell and to the cell discharge circuit. The cell measurement circuit is configured to measure a voltage of the at least one cell before activation of the cell discharge circuit and after activation of the cell discharge circuit. The cell measurement circuit compares the voltage before activation of the cell discharge circuit to the voltage after activation of the cell discharge circuit to detect if an error in the voltage measurement occurred.
