Due to the absence of liquid electrolyte, the power supply keeps running even in case of housing penetration

RT-Project Technologies included in Rostec State Corporation participated in the development of import-substituted power supplies that are non-susceptible not only to arctic frost and heavy vibrations but also to bullets. Unlike traditional electrolyte batteries, the new products can be mounted in any position. The product can be used for starting engines in heavy military vehicles as well as in uninterruptible power supply systems at command posts and communication centers. 

The new batteries have a special design — they are free of liquid electrolyte, electrolyte is absorbed by dedicated fiberglass “sponges”. Therefore, electrolyte spill is prevented even in case of housing penetration, and the power supply keeps running. Moreover, the products can be installed in any position and provide fail-safe operation in heavy vibration conditions common to cross-country movement of tracked platforms. Power supplies using such technology haven’t been made before in Russia for military purpose. 

“Energy security and self-sufficiency of troops are now directly associated with the quality of secondary power supplies. Military and special-purpose vehicles shall be able to be started in arctic frost and not to lose their capacity when the armored capsule is overheated. The product line created in cooperation with Impuls Research and Development Company has proved effective during comprehensive testing in extreme temperatures ranging from -50°C to +50°C with any battery orientation during mounting and in the heaviest vibration conditions as well as in case of housing penetration. Service life of these products is measured in a decade, and the manufacturing capacities are able to produce two million batteries annually without regard to foreign components,” said Aleksandr Nazarov, Deputy General Director of Rostec.
