The problem of increasing the performance of batteries operating under severe temperature conditions is of current interest for the development of stand-alone energy systems. The system maintaining battery optimal temperature is proposed. The system combines battery thermal insulation, heating and monitoring and allows maintaining battery temperature with minimum energy consumption. The paper describes the experimental study of the proposed system. The experimental results analysis indicates internal resistance decrease of 47.9% and discharge energy increase of 55.7% and proves the technical efficiency of the system.

The problem of increasing the performance of batteries operating under severe temperature conditions is of a current interest for development of stand-alone power systems. The approach implying the use of the system for battery optimal temperature maintenance is introduced. The system combines battery thermal insulation, heating and monitoring and allows maintaining battery temperature with minimum energy consumption. The design of the experimental assembly for studying technical and economic efficiency of the proposed approach and the thermal design of structural elements of the system are given.
