We consider the problem of providing operational characteristics of power sources of portable communication devices in low-temperature way of control. Objectives. 1. To justify the principle of operation of the device for compensation of heat losses of storage batteries in low temperature conditions by the method of temperature control with the use of different
heating elements. 2. To develop a mathematical model describing the process of maintaining an optimum heat range of the battery due to the use of chemical and electrical heating elements. 3. To develop key concepts and assumptions to mathematical models. As a chemical heating element, supersaturated sodium acetate NaCH3COO∙3H2O is used. The electric heating element is made based on posistors.
Key words: battery, temperature control, electric heating element, heat storage material, heat accumulator phase transition.
