Welcome to Hebei Nanfeng!

NF Group 15KW Electric Bus BTMS 7KW Thermal Management System For Electric Vehicles

Short Description:

The BTMS is an integrated, modular thermal solution for new energy commercial vehicles (trucks, buses, cold-chain logistics).

It delivers stable cooling and linear, surge‑free heating with fast response. Engineered for heavy loads, frequent stop‑starts, and long hauls, it adapts to mainstream battery types and solves key pain points—range degradation, low‑temperature capacity loss, and high upkeep costs.

The NF GROUP NFEHP series water‑cooled unit ensures reliable, efficient thermal regulation, extending battery life and reducing total operating expenses in real‑world fleet applications.

EV Thermal Management System Description

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.

It offers:

  • Integrated design and installation – compact and easy to mount.
  • Modular architecture – allows convenient capacity expansion.
  • Stable cooling and heating output – with a surge‑free, linear heating curve and fast ramp‑up rate, ensuring precise temperature control without sudden spikes.
  • High cooling efficiency – uniform temperature distribution across the entire battery pack, making it the preferred choice for mainstream electric vehicles.

Furthermore, the NFEHP series features a flexible heating configuration, allowing customers to select heating power from 3 kW to 15 kW to suit various application needs. This adaptability effectively addresses cold‑start issues at low temperatures, extends battery service life, and enhances overall operating performance – all while reducing total cost of ownership.

With over three decades of innovation and a commitment to quality, Nanfeng Group delivers reliable, high‑performance thermal management solutions that empower commercial fleets to operate efficiently in any environment. Our BTMS is not just a component – it is a strategic enabler for sustainable, profitable e‑mobility.
