A method of monitoring electric battery capacity effects evaluation of battery capacity in terms of battery current and battery voltage in a succession of monitoring cycles, scales down an influence of battery current on the evaluation as the succession of monitoring cycles, progresses, and scales up an influence of battery voltage on such evaluation as the succession of monitoring cycles progresses. A similar method effects an assessment of battery capacity during alternating battery discharge operations and battery charging operations over a recurrence of monitoring cycles, detects a decline of attainable battery charge capacity during battery charging operations, and modifies its assessment in response to the detected decline of attainable battery charge capacity. A related method effects evaluation of battery capacity during battery discharges in a succession of monitoring cycles, effects an adjustment of such evaluation of battery capacity in a succession of further monitoring cycles during battery charge restoration between battery discharges, and effects a modification of the adjustment during a decline of battery charging efficiency in a vicinity of full charge restoration.

Electric battery monitoring systems

A process is provided for forming the native oxide on a semiconductor surface comprising Hg.sub.1-x Cd.sub.x Te, where x ranges from 0 to 1. The process comprises exposing the semiconductor surfce to a mixture of ozone and oxygen containing an effective amount of ozone sufficient to form a native oxide thereon. The desired amount of ozone is conveniently obtained by passing oxygen from a source through an ozone generator provided with a source of high voltage.
