Batteriemodul mit nichtwässrigem Elektrolyt für einen künstlichen Satelliten

摘要

An artificial satellite is equipped with solar batteries and a non-aqueous electrolyte battery module for artificial satellite (i.e., a lithium battery). The non-aqueous electrolyte battery module is provided with a non-aqueous electrolyte battery, a temperature sensor, a charged state measurement sensor, and a computer for receiving signals output from the sensors. The managed temperature of the non-aqueous electrolyte battery in a solstice season is set so as to become equal to or lower than the managed temperature of the battery when the satellite is in the solstice season. The computer controls a temperature controller, thereby maintain the managed temperature of the battery within a given temperature range. The charged state of the lithium battery is controlled by means of turning on or off a charging switch under the control of computer. When the satellite is in the eclipse season, the managed charged state of the non-electrolyte battery is controlled so as to be a value of 50% or more. When the satellite is in the solstice season, the managed charged state of the non-aqueous electrolyte battery is controlled so as to be a value of 75% or less.
