Russia has begun producing advanced sodium batteries that operate at -40°C.
Rubrux, a Skolkovo resident, has developed and launched the first domestically produced battery module based on sodium-ion cells (the HVBS series). This new product is designed to be a more affordable and durable alternative to traditional lithium-ion batteries for applications such as electric vehicles, industrial equipment, and stationary energy storage systems.
The key feature of the HVBS-360-50 module is its ability to operate effectively in harsh climates: sodium-ion technology maintains high capacity at temperatures of -30 to -40°C.
Sodium-ion batteries have a nominal voltage of 360 V and can withstand several thousand charge-discharge cycles without cell degradation. These batteries are less prone to overheating and spontaneous combustion (thermal runaway) than conventional lithium batteries.
The Rubrux development is a completely independent product. The battery management system (BMS) is built using domestic microcontrollers manufactured by NIIET (Element Group).
The first prototypes are already undergoing a series of final bench tests. HVBS-360-50 modules are planned for installation in electric and hybrid vehicles, municipal and airfield equipment, industrial loaders, and autonomous power systems.
