Abstract
An inventive, new system that measures gas composition and pressure in the headspace of an aqueous electrolyte battery is described. The system includes a microcontroller that can use the composition and pressure information to connect a third electrode to either the anode(s) or the cathode(s) in order to balance the state of charge between the two. Results have shown that such a system can control the gas pressure inside a sealed flooded aqueous electrolyte battery to remain below 20 kPa (3 psi) and greatly extend the useable life of the battery.
