BATTERY WATERING EVENT DETECTION USING A TEMPERATURE SENSOR

摘要

A method of battery cell monitoring includes measuring a temperature of an electrolyte (block 700) in a battery cell using a temperature sensor, outputting from the temperature sensor a plurality of electrolyte temperature signals (block 710) indicative of the temperature of the electrolyte over time, providing the plurality of electrolyte temperature signals to a system controller (block 710), determining by the system controller a sudden transition in the electrolyte temperature signals (block 720), and logging a watering event data indication (block 725) in a memory in response to calculating the sudden transition.
