Rosatom State Corporation unveiled a universal battery designed for public and commercial electric transport at the international Atomexpo-2024 forum. According to the organization’s press service, this new solution represents an accessible Russian product aligned with the capabilities of leading global manufacturers, reflecting Rosatom’s commitment to advancing domestic energy storage technology on the world stage.
Rosatom clarified that the new battery design takes into account the exact parameters demanded by automobile manufacturers, offering enhanced flexibility within the vehicle battery system. This adaptability is intended to support different vehicle classes and configurations while maintaining high performance and reliability across varied use cases.
The development process drew on a detailed analysis of experience gained from producing multiple vehicles intended for public and commercial use that rely on rechargeable energy storage. This evidence-based approach helped identify practical requirements and operational conditions, ensuring the final solution met real-world needs without compromising safety or efficiency.
As a result, the Rosatom team delivered a battery system that aligns with the specifications of current and prospective automakers. The design emphasizes seamless integration with existing vehicle architectures, reducing the need for extensive redesigns and enabling faster adoption across platforms and markets.
Rosatom stressed that adopting these batteries does not demand substantial alterations to vehicle structures. The system is capable of addressing roughly 80 percent of the traction battery requirements of the Russian electric vehicle market, supporting a broad spectrum of applications while maintaining compatibility with established manufacturing practices.
The battery system features universal cells that allow a wide range of voltage and capacity configurations, from 1 up to 16, to suit diverse customer requirements. The design also supports rapid charging, which is crucial for maintaining uptime and operational efficiency in fleet deployments and high-demand scenarios.
The new solution is suitable for urban public transport and can power electric buses and trolleybuses with extended autonomous operation. It also accommodates medium-duty and light commercial vehicles, as well as heavier electric trucks, electric ships, and electric trains, illustrating versatility across multiple transport sectors and future mobility architectures.
The battery casing uses a high-strength aluminum alloy, and the cells are based on Li-NMC chemistry (lithium-nickel-manganese-cobalt). The energy density reaches approximately 260 watt-hours per kilogram. A sophisticated temperature control system ensures robust performance across Russia’s diverse climates, allowing operation from -40 °C to +40 °C without compromising safety or longevity.
End-of-year plans include factory testing and evaluation of the batteries in real vehicle applications at dedicated test sites, validating performance, reliability, and interoperability with different vehicle platforms before broader commercial deployment.
