Claim 0:
1. A thermal battery system comprising:
a thermal battery assembly including a plurality of thermal 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,
wherein the ignition circuit comprises:
a first terminal configured to apply a first ignition voltage;
a second terminal configured to apply a second ignition voltage;
a plurality of first wires and a plurality of second wires; and
a plurality of first switches and a plurality of second switches, and

wherein each of the plurality of first wires connects to each of first ignition electrodes of the thermal batteries arranged in each of the plurality of thermal battery modules, and each of the plurality of second wires connects to each of second ignition electrodes of the thermal batteries arranged in each of the plurality of thermal battery modules, and
each of the plurality of first switches connects the first terminal to a corresponding one of the plurality of first wires, and each of the plurality of second switches connects the second terminal to a corresponding one of the plurality of second wires, and
the control unit is configured to turn on one of the plurality of first switches and one of the plurality of second switches and ignites a thermal battery in which a first ignition electrode is connected to a first wire corresponding to the turned-on first switch and a second ignition electrode is connected to a second wire corresponding to the turned-on second switch.
