Energy storage in extremely low temperatures

The dynamic development of battery technologies is making electricity storage less dependent on climatic conditions. Until recently, freezing environments posed a serious challenge to the stable operation of BESS systems. Today, however, innovative solutions such as those implemented by the Chinese company Poweroad enable reliable performance even at temperatures as low as -40°C.

Research and development as the foundation of innovation

Poweroad conducts energy storage system development in five specialized R&D centers across China. The company designs its own Battery Management Systems (BMS), Energy Management Systems (EMS), and dedicated cloud platforms. This approach allows it not only to deliver products resistant to extreme conditions, but also to ensure their optimal performance in diverse operational environments.

So far, Poweroad has completed over 500 commercial and industrial projects in European markets (including Belgium, Sweden, Finland, and Italy). The company emphasizes that its activity is not limited to supplying hardware. It also provides pre-sales consulting, technical training, and comprehensive after-sales support. This enables partners to fully unlock the potential of their energy storage investments.

Arctic-class solutions

The best proof of Poweroad’s technology resilience is the installation at the Karamay oilfield in China. The 18.43 MWh BESS deployed there operates seamlessly in temperatures down to -40°C, using an integrated liquid heating and cooling system. The system has already run for more than 8,760 continuous hours, replacing over 50% of the original diesel sources.

Its mobile design allows for easy relocation to new sites—a particularly important factor in the extractive sector, where infrastructure cycles usually last 1–2 years.

Poweroad’s technology is especially relevant for Northern and Eastern Europe, where winter temperature drops impose high demands on energy infrastructure. Thanks to its patented thermal management system, the company’s storage units can maintain full capacity at temperatures below -30°C, switch instantly from standby to active mode in case of failure, and take advantage of remote diagnostics.

Such capabilities strengthen the resilience of power grids, reduce operating costs, and limit dependence on conventional energy sources.

Supply chain stability and market outlook

According to Joelle Li, Poweroad’s Director of Marketing and Brand, the growing demand for BESS—driven by the dynamic expansion of renewables—is also linked to raw material price fluctuations and cost pressures. The company relies on cooperation with trusted suppliers, such as CATL, and pursues active supply chain management strategies.

Although some local markets may experience short-term oversupply, the global trend clearly points to continued growth in demand. Poweroad is addressing these challenges with flexible, high-quality solutions tailored to the specific needs of each market.
