Welcome to Hebei Nanfeng!

NF Group 3-20KW Battery Thermal Management System OEM For Electric Bus BTMS

Short Description:

The Battery Thermal Management System (BTMS) is an integrated, modular thermal regulation platform specifically engineered for new-energy commercial vehicles—including heavy-duty trucks, transit and coach buses, and refrigerated logistics vehicles. It delivers stable, precision-controlled cooling and linear, surge-free heating with sub-second dynamic response, ensuring optimal battery operating temperature across diverse duty cycles. Designed to endure demanding operational profiles—such as sustained high-load operation, frequent stop-start cycling, and extended-range hauls—the system supports mainstream lithium-ion chemistries (NCM, LFP, and NCA) and directly mitigates three critical performance challenges: state-of-charge (SoC)–dependent range degradation, low-temperature capacity derating, and elevated lifecycle maintenance costs.

The NF Group NFEHP series water-cooled BTMS unit delivers robust, energy-efficient thermal regulation under real-world fleet operating conditions. Field validation across more than 200 million cumulative kilometers demonstrates a battery service life extension of up to 25%, alongside measurable reductions in total cost of ownership (TCO) driven by lower energy consumption, extended coolant service intervals, and significantly fewer thermal-related warranty claims.

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 engineered for new-energy commercial vehicles—covering heavy- and light-duty trucks, city and coach buses, and refrigerated logistics vans. It is rigorously validated for real-world demands: steep grades, high payloads, urban stop-start operation, long-haul duty cycles, and extreme ambient temperatures (–30°C to +55°C). Fully compatible with mainstream battery chemistries—including LFP and NCM—the system ensures stable performance, consistent range, and reduced maintenance, maximizing fleet uptime.
