NF Group Electric Bus Thermal Management System 15KW

The Battery Thermal Management System (BTMS) serves as the “silent engine” and “guardian” of electric vehicle batteries. Its core mission is to maintain the battery pack’s temperature within the optimal operating window of 15–35 °C through precise cooling, heating, and thermal equalization, thereby ensuring performance, safety, and longevity. Lithium-ion batteries are highly temperature‑sensitive: excessive heat can cause leakage, smoke, or even combustion and explosion; severe cold increases internal resistance, drastically cuts usable capacity, and shrinks driving range; and uneven temperature distribution accelerates cell aging, shortening the entire pack’s service life. Effective thermal management is therefore indispensable for modern new‑energy vehicles.

Established in 1993, Nanfeng Group is a diversified enterprise operating six manufacturing facilities. As one of China’s leading suppliers of new‑energy vehicle components and a designated supplier for Chinese military vehicles, we bring decades of engineering excellence to the industry. Our extensive product portfolio includes high voltage coolant heaters, electronic water pumps, BTMS units, electric air compressors, EPS/EHPS steering systems, electric A/C compressors, three‑way valves, parking heaters and air conditioners, plate heat exchangers, and more. This broad expertise enables us to deliver integrated, turnkey thermal solutions.

BTMS – Designed for Commercial Vehicle Challenges

Nanfeng’s BTMS is purpose‑built for new‑energy commercial vehicles – heavy‑duty trucks, light‑duty trucks, buses, and cold‑chain logistics vans. Recognizing the harsh realities of hill climbing, heavy loads, frequent stop‑starts, long‑haul trips, and diverse climatic conditions, our system deeply adapts to mainstream battery chemistries. It effectively resolves industry pain points such as rapid range degradation, significant low‑temperature capacity loss, and high maintenance costs.

NFEHP Series – Thermal Management System For Electric Vehicles

The NFEHP series represents our flagship water‑cooled BTMS solution.

Key benefits include:

• Integrated design & installation: compact footprint for straightforward mounting.
• Modular structure: supports convenient capacity expansion.
• Stable cooling and heating output: delivers a linear, surge-free heating profile with fast response, enabling precise temperature control and eliminating abrupt temperature spikes.
• High cooling efficiency: achieves even temperature distribution across the full battery pack, making it an ideal solution for mainstream electric vehicles.

In addition, the NFEHP series boasts flexible heating configurations. Customers can select heating power ranging from 3 kW to 15 kW to match diverse application requirements. This flexibility effectively mitigates low-temperature cold-start challenges, prolongs battery lifespan, improves overall operational performance, and lowers total cost of ownership.

Backed by more than 30 years of technical innovation and strict quality dedication, Nanfeng Group provides robust, high-performance thermal management solutions. These solutions help commercial fleets operate efficiently across all working environments. Our BTMS is far more than a standalone component; it serves as a strategic enabler for sustainable and profitable electric mobility.
