NF 4-Way Electronic Valve for BTMS EV Vehicle High Precision Flow Control Valve
Product Description
Core strengths
1. Precise multi loop control (BTMS core capability)
Four port flexible switching: realizing the free switching of coolant paths between battery pack, motor, electronic control, radiator, heat pump/chiller, cabin heater, supporting multiple modes such as large cycle, small cycle, waste heat recovery, heat pump heating/cooling, etc.
Proportional/step-by-step flow regulation: Different from traditional on-off valves, it can linearly/stepwise regulate flow, accurately control battery pack temperature difference (± 1-2 ℃), and improve heat pump COP and system energy efficiency.
Low leakage and low flow resistance: Optimized flow channel design, extremely low cross leakage, low pressure drop, reduced water pump power consumption, and improved vehicle endurance.
2. Efficient energy recovery and energy conservation
Winter waste heat utilization: Directly introducing motor/electronic control waste heat into battery preheating or cabin heating, reducing PTC power consumption and significantly improving low-temperature endurance.
Efficient heat dissipation in summer: Quickly direct the heat from the battery/electric drive to the radiator or chiller, avoiding high temperature power limitation.
Low power drive: commonly uses stepper motors/lock-in actuators, which only consume power during switching and do not require continuous power supply to maintain position, reducing overall vehicle energy consumption.
3. System integration and reliability
High integration: One four-way valve can replace multiple two-way/three-way valves and complex pipelines, reducing joints, lowering leakage risks, simplifying layout, and saving space.
Wide voltage and communication compatibility: Supports 12V/24V, compatible with PWM/LIN/CAN, easy to connect to the vehicle thermal management controller.
Modularity and durability: Suitable for different platforms, * * IP67+* * protection, meeting the requirements of vehicle grade vibration, temperature cycling, and lifespan.
4. Intelligence and Security
Real time closed-loop control: Combined with temperature/flow sensors, it achieves adaptive temperature control for all working conditions, quickly responding to scenarios such as fast charging, climbing, and low temperature.
Fault safety mode: supports power-off protection/failure orientation to prevent thermal runaway and enhance system safety.
