Claim 6:
7. An ignition method for a thermal battery system comprising
a thermal battery assembly including battery modules each comprising a plurality of thermal batteries, an ignition circuit connected to the plurality of thermal batteries in the thermal battery assembly, and a control unit configured to control the ignition circuit to ignite a selected thermal battery in the thermal battery assembly, the ignition method comprising:
selecting, by the control unit, one of a plurality of first wires connecting to one of first ignition electrodes of thermal batteries arranged in each battery module, and turning on a first switch for connecting the selected first wire to a first terminal;
selecting, by the control unit, one of a plurality of second wires connecting to one of second ignition electrodes of thermal batteries arranged in one of the battery modules, and turning on a second switch for connecting the selected second wire to a second terminal;
igniting, by the control unit, a thermal battery in which a first electrode is connected to the selected first wire and a second electrode is connected to the selected second wire; and
repeating, by the control unit, the turning on of the first switch, the turning on of the second switch, and the igniting of the thermal battery.
