The temperature stabilizer is designed for thermally activated thermal chemical current sources, in which it is necessary to maintain the optimal thermal balance in a limited amount for a long time. In the work the formulated problem has been solved by stabilizing the battery temperature in the optimal range. The stabilizer of the temperature range of the current source, using for its work the energy battery itself, has been presented. The stabilizer distinctive feature is the combination of the of the heating element function and of the temperature sensor. The experimental studies with the instrument control of the stabilizer work quality have been performed on the layout and real batteries. The temperature stabilizer, with the help of which it has been shown that it is possible to maintain the specific temperature for quite a long time (up to one hour) at high energy efficiency of the current source thermal chemical battery, has been developed and implemented experimentally. This has been achieved due to the fact that the energy of the battery is consumed almost only in the heating mode. The stabilizer is small, easy to implement and to adjust. The presented stabilizer solution can be used in other applications requiring the temperature stabilization without using an additional temperature sensor.
