Abstract:

A lithium battery is provided with an energy monitor that continuously indicates the energy remaining in the battery. An electrolytic coulometer is connected in series with the and has a cantilevered cathode which increases its mass in proportion to the total amount of the cathode and hence its resonant frequency changes in proportion to the total current, a mechanical transducer in contact with the electrolytic coulometer causes the cantilevered cathode to resonate at different frequencies which is monitored to provide a continuous reading of remaining battery energy.
