CONTROL OF THE CHARGING OF PRESSURIZED GAS-METAL ELECTRICAL STORAGE CELLS ABSTRACT OF THE DISCLOSURE A process and apparatus for controlling the charging of pressurized gas-metal cells such as nickel- hydrogen cells, to prevent detrimental overcharging, wherein the time rate of change of a battery gas pressure index is monitored as a control parameter. When the time rate of change of the index falls below a preselected value, charging is discontinued. The cell gas pressure index can be gas pressure itself, or a quantity which is responsive to, and depends upon gas pressure, such as the deformation of a cell component.
