Abstract
A method of battery cell monitoring includes measuring a temperature of an electrolyte in a battery cell using a temperature sensor, outputting from the temperature sensor a plurality of electrolyte temperature signals indicative of the temperature of the electrolyte over time, providing the plurality of electrolyte temperature signals to a system controller, determining by the system controller a sudden transition in the electrolyte temperature signals, and logging a watering event data indication in a memory in response to calculating the sudden transition.
