Energy Storage Thermal Management Control

Energy Storage Thermal Management Schematic

Schematic diagram showing the control logic for an energy storage thermal management system

The control system gathers pressure and temperature data from sensors to regulate actuator speed, position, and current, ensuring batteries operate within their optimal temperature range. It includes advanced self-diagnostic and fault-operation modes to maintain system functionality and prevent failures.

● High ambient temp OR battery temp exceeds threshold: Air conditioning system activates to meet cooling demand.

● Ambient temp low AND battery temp below threshold: Water pump operates, dissipating heat through pipes/circuit.

● Ambient temp low BUT battery temp exceeds threshold: Water pump operates, solenoid valve switches circuit to radiator mode.

● System stopped AND battery temp below threshold: Thermal management system stops.

● System stopped BUT battery temp exceeds threshold: Thermal management system delays shutdown until battery temp falls below threshold.

8kW Energy Storage Structure

Integrated Liquid Cooling Unit

This unit integrates the fan, compressor, water pump, plate heat exchanger, electric heater, and electronic controls into a highly compact assembly with excellent space utilization. For maintenance and (after-sales service), single-side access allows for comprehensive inspection and servicing of the entire unit.

System Components

High-strength plate heat exchangers, microchannel parallel-flow heat exchangers, and DC high-lift pumps effectively reduce system weight and enhance reliability. Inlet/outlet pressure detection provides early warning to prevent system faults due to low coolant levels.

Platform-based Simulation Model

1D fluid simulation models are employed to calculate system flow distribution and heat transfer performance. This determines any variance between the liquid cooling loop's capabilities and project targets, validates component selection, improves development efficiency, and reduces costs. The model can be scaled for multiple battery clusters and water temperature management.
