METHOD OF NICKEL-HYDROGEN ACCUMULATOR PREPARATION FOR NORMAL OPERATION WITH MAN-MADE SATELLITES Russian patent published in 2012 - IPC H01M10/44 

FIELD: electricity.

SUBSTANCE: invention is related to electrical industry and can be used for preparation of nickel-hydrogen accumulators for normal operation with man-made satellites, mainly for non-pressurised earth satellites with radiation cooling. Method of nickel-hydrogen accumulator preparation for normal operation with man-made satellites includes provision of environment temperature under launch vehicle fairing of carrier-rocket spacehead, initial charge by rated current with limitation of temperature increase for accumulator and further boosting by low current value in conditions of limited heat removal. At that pause should be taken between initial charge by rated current and boosting by low current value. According to invention charging with rated current and boosting with low current value should be performed within preset time periods with determinant limitation on accumulator temperature gradient in regard to ambient temperature for each individual mode; besides commencement of boosting should be planned in compliance with minimum time requirement before commencement of prohibition for electric works with spacehead as stipulated by process of carrier-rocket launching.

EFFECT: improvement of functional reliability and provision of effective charge for nickel-hydrogen accumulators at limited heat removal.
