Solving the challenges of high-cold operation for coaches! Integrated thermal management system

The electrification of domestic public transportation continues to deepen, with steady growth in the number of new-energy buses and tourist coaches. Meanwhile, demand for overseas bus exports remains strong. However, frequent start-stop cycles and large temperature fluctuations between day and night—especially in cold regions where batteries require preheating and face cooling challenges in summer—have exposed shortcomings in traditional decentralized thermal management systems, such as uneven temperature control, high energy consumption, and complex maintenance. As a result, integrated thermal management has become an essential industry requirement.

NF Group has launched its 15kW integrated thermal management system specifically designed for 8–12 meter electric buses. This solution combines battery cooling, low-temperature preheating, and temperature balancing into one unit, capable of operating reliably across a wide range of environmental conditions from -30°C to 50°C. With excellent temperature control precision, it effectively reduces temperature differences within battery packs, mitigates thermal risks, and extends the service life of power batteries. Equipped with intelligent CAN bus communication and multiple protections against over-temperature and overload, the system meets IP67 automotive-grade protection standards. It is perfectly suited for heavy-duty, high-frequency operations typical in public transit scenarios. Its modular design simplifies vehicle assembly and after-sales maintenance, while supporting OEM customization and development.

This system significantly reduces overall thermal management energy consumption and alleviates winter range degradation issues. As the global and domestic new-energy bus markets expand, original equipment manufacturers (OEMs) and fleet operators are placing increasing demands on thermal management reliability. This system serves as a key benchmark product for OEMs, enhancing vehicle adaptability under extreme conditions while helping fleets reduce operational and maintenance costs. It represents a highly competitive thermal management solution for electric bus projects.
