NF Group 3-20KW BTMS OEM For Electric Vehicles

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 thoughtfully designed for new-energy commercial vehicles—including heavy- and light-duty trucks, city and coach buses, and refrigerated logistics vans. We know your vehicles face real-world challenges: steep hills, heavy payloads, stop-and-go city routes, long-distance hauls, and everything from freezing winters to scorching summers. That’s why our system is carefully tuned to work seamlessly with today’s most common battery types (like LFP and NCM), helping keep performance steady, range reliable, and maintenance manageable—so your fleet stays on the road, day after day.

NFEHP Series – Thermal Management System For Electric Vehicles

The NFEHP series is our flagship water-cooled Battery Thermal Management System (BTMS)—designed with care to support your vehicles’ performance, reliability, and longevity.

What makes it especially thoughtful for your needs:
• Integrated design—compact and easy to install, helping simplify integration into your existing platform;
• Modular flexibility—so you can scale cooling capacity as your fleet grows, without complicated re-engineering;
• Gentle, precise temperature control—delivering smooth, surge-free heating and responsive cooling, keeping battery temperatures steady and safe—even during demanding driving conditions;
• Even, balanced cooling—ensuring consistent temperatures across the entire battery pack, which helps batteries perform at their best and last longer.

We’ve also built in adaptable heating options—from 3 kW up to 15 kW—so you can choose just the right level of warmth for your specific application. This means quicker, more reliable cold-weather starts, healthier batteries over time, improved vehicle responsiveness, and lower operating costs—all working together to support your fleet’s success.

For over 30 years, Nanfeng Group has been partnering with customers like you—listening, learning, and refining our thermal solutions with dedication and care. The NFEHP series reflects that commitment: it’s more than a component—it’s a trusted companion on your journey toward sustainable, efficient, and rewarding electric mobility.
