Abstract
A system for monitoring the quality of electrolyte for a battery cell includes a reservoir configured to receive electrolyte, a capacitive sensor disposed in the reservoir, and a control module in communication with the capacitive sensor. The capacitive sensor is configured to sense a capacitance of the electrolyte when received in the reservoir. The control module is configured to receive a signal from the capacitive sensor indicative of the capacitance of the electrolyte, and determine whether the received electrolyte is contaminated based on the capacitance of the electrolyte and a defined threshold. Other example systems and methods for monitoring the quality of electrolyte for battery cells are also disclosed.
