The control system gathers pressure and temperature data from sensors to regulate the operating speed, position, and current of the actuators, thereby ensuring that the battery functions at an optimal temperature. Additionally, the system features enhanced self-diagnosis and fault operation modes to maintain normal system operation and prevent failures.
· High ambient temperature and battery temperature exceed the threshold limit.
The air conditioning system must operate effectively to meet the battery cooling requirements.
· The ambient temperature is not high, and the battery temperature does not exceed the threshold limit.
The water pump operates by dissipating heat through the pipeline.
· The ambient temperature is not high, but the battery temperature exceeds the threshold.
The water pump operates, and the solenoid valve control circuit switches to the radiator’s operational circuit.
· The energy storage system has ceased functioning, and the battery temperature remains below the threshold.
The thermal management system has stopped functioning.
· The energy storage system has ceased functioning due to the battery temperature exceeding the threshold.
The thermal management system delays operation until the battery temperature reaches the specified threshold.
Energy Storage Thermal Management Schematic
- The system primarily consists of a compressor, condenser, plate heat exchanger, circulating water pump, low-temperature radiator, electronic fan, and other components.
- The system employs an electronic three-way valve to split the battery cooling circuit into two modes: air conditioning cooling and natural forced air cooling. This design effectively reduces energy consumption for battery cooling in low-temperature environments and enhances overall system efficiency.
- With an equal path circuit design, the flow distribution within the battery pack is more uniform, resulting in a smaller temperature difference between battery cells and an extended battery life.
- The flat platform design offers robust scalability, and the choice of adjustment devices can accommodate the energy storage and heat exchange requirements for various discharge rates and scales.
- The system features a quick plug-in design, high modularity, easy installation, and consistent product quality.
Thermal Management Simulation
Platform-Based Simulation Model
Use a one-dimensional fluid simulation model to calculate the flow distribution and heat transfer performance of the system loop. This will help determine the differences between the flow and heat transfer capacities of the liquid cooling loop and the target specifications. Additionally, it will verify the rationality of the selection, improve development efficiency, and reduce development costs. The model can also be expanded to accommodate multiple battery clusters and manage water temperature effectively.
The simulation system includes:
- Large System Flow
- System Pressure Distribution
- Flow Resistance Characteristics
- Battery Circuit Flow Distribution
- Heat Transfer Performance

Integrated Liquid Cooling Unit
- The unit integrates fans, compressors, water pumps, plate heat exchangers, electric heating, electric controls, and other components, achieving high integration and optimal space utilization.
- For maintenance and after-sales service, the one-sided disassembly and assembly of the system facilitate a comprehensive inspection and maintenance of the entire machine.
System Components:
- High-strength plate heat exchangers, microchannel parallel flow heat exchangers, and direct current high-lift water pumps effectively reduce system weight while enhancing system reliability.
- Inlet and outlet pressure detection functions can provide early warnings to prevent system failures caused by water shortages.
