The invention relates to a
satellite-borne storage battery dual-interval autonomous
temperature control method. According to the method, under the premise of a permitted automatic
temperature control function of a
satellite storage battery, when actual storage battery
discharge current is smaller than a set
discharge current alarm threshold or
solar battery array current is greater than a set matrix current alarm threshold value, the storage battery
temperature control work is in a first interval mode; and when the actual storage battery
discharge current is greater than the set
discharge current alarm threshold value and the
solar battery array current is smaller than the set matrix current alarm threshold value, the storage battery temperature control work is in a second interval mode. Control management can be performed on the storage battery temperature both in the first interval
temperature control mode and in the second interval
temperature control mode. The method provided by the invention changes the current situation of only adopting single interval control in
satellite storage battery temperature control, and matches the battery
discharge current and the
solar battery array current with storage battery temperature change, thus enhancing the accuracy and flexibility of satellite storage battery temperature control, and improving the autonomous temperature control
management quality of the storage battery.
