Temperature and voltage controlled multi-level battery electrolyte level monitor

A device for monitoring a battery having multiple cells and a varying electrolyte level, the device comprising:

• a water conduit connectable to a water source;
• a plurality of nozzles adapted to be mounted on the battery in communication with the multiple cells respectively;
• the plurality of nozzles being connected to the water conduit so as to receive a flow of water from the water conduit through the nozzles for distribution to the multiple cells of the battery;
• a flow sensor operatively connected to the water conduit so as to be arranged to detect a flow of water through the water conduit;
• a watering indicator which is indicative that the battery needs watering;
• a controller operatively connected to a pair of terminals of the battery and to the flow sensor;
• the controller including a memory storing watering criteria and programming instructions thereon and a processor for executing the programming instructions so as to be arranged to (i) communicate with the flow sensor to determine when the battery has been watered (ii) determine a watering condition in response to watering criteria since last watering of the battery being met, and (iii) activate the watering indicator in response to determination of the watering condition.

A device for monitoring a battery, the device comprising:

• a temperature sensor adapted to be operatively connected to the battery so as to sense a temperature of the battery;
• a voltage sensor configured to monitor a voltage across two terminals of the battery;
• a controller in communication with the temperature sensor and the voltage sensor, the controller including a memory storing programming instructions thereon and a processor for executing the programming instructions whereby:
• (i) the controller is adapted to determine an overheated condition when the temperature sensor senses that the temperature is above a prescribed temperature threshold;
• and
• (ii) the controller is adapted to compare the voltage monitored across the terminals to charge completion criteria and to determine the overheated condition when the voltage monitored across the terminals meets the charge completion criteria, in which the charge completion criteria are indicative of completion of a charging cycle of the battery;
• and
• a fan being operatively connected to the controller so as to be operable from an inactive state to an active state responsive to determination of the overheated condition.
