BATTERY ELECTROLYTE LEVEL INDICATOR

摘要

A battery electrolyte monitor including a probe and a control circuit. The control circuit includes a capacitive element within the probe. The probe is acid resistant, and therefore the probe protects the capacitive element from contact with the battery electrolyte. The control circuit periodically charges and discharges the capacitive element using direct current. Depending on at least one of a charging characteristic and a discharging characteristic, the control circuit determines the electrolyte level. If the electrolyte is below a desired minimum level, the control circuit illuminates an indicator light.
