NF BTMS Refrigeration 4.5 kW Heating 5 kW Thermal Management System for Battery system

NF Battery Thermal Management Systems (BTMS) are engineered specifically for new-energy commercial vehicles, delivering precise, application-optimized thermal regulation for traction batteries across a broad spectrum of vehicle platforms—including battery electric buses, hybrid electric buses, range-extended light-duty trucks, hybrid heavy-duty trucks, battery electric construction machinery, battery electric logistics vans, battery electric excavators, and battery electric forklifts.
By maintaining battery temperatures within the optimal operational envelope—despite ambient extremes ranging from high-heat climates to arctic-grade cold—the system substantially extends service life, improves charge/discharge efficiency, and enhances functional safety and thermal resilience.

Performance Features

1. Robust and Application-Optimized Design: Compact, integrated enclosure with IP67-rated sealing and ISO 9223 Class C5-M corrosion resistance. All critical components—including pumps, valves, and heat exchangers—are configurable for coolant or thermal oil operation. Intuitive HMI and programmable operating modes (e.g., constant-temperature regulation, predictive pre-conditioning, and energy-recuperative cooling) support diverse duty cycles. Temperature control accuracy is ±0.5 °C (±1 σ), validated per ISO 16750-4, ensuring repeatable performance across thermal shock and vibration environments.
2. Intelligent CAN-Based Control with Multi-Layer Safety Assurance: Real-time bidirectional communication via high-speed CAN 2.0B enables centralized monitoring and actuation of voltage, current, SoC, SoH, coolant temperature/pressure/flow, and cell-level thermal gradients. Protection logic implements ASIL-B–compliant hierarchical safeguards—including over/under-voltage, over-current, dual-stage over-temperature (cell and loop), coolant leakage detection, and pressure decay monitoring—thereby mitigating thermal runaway propagation risk in accordance with ISO 26262 and GB/T 31467.3.
3. Compact Integration with Verified EMC Immunity: Modular architecture reduces footprint by up to 35% versus conventional systems and supports rapid field service. Certified to CISPR 25 Class 5 and ISO 11452-2/4/8, the BTMS  exhibits zero electromagnetic interference with ADAS sensors, motor inverters, and vehicle gateways under full-load transient conditions.
4. Scalable, Platform-Independent Modularity: Standardized hydraulic interfaces (DIN 2353) and CAN/FlexRay signal protocols enable seamless integration across OEM platforms. Chiller, PTC heater, and intelligent manifold modules can be deployed in parallel or series configurations to match battery pack capacity (from 50 kWh to 600 kWh), thermal load (1–15 kW), and spatial constraints without redesign.
