This utility model discloses a thermal management system suitable for containerized energy storage systems, comprising an air conditioning refrigerant circuit and a battery thermal management circuit, both of which include plate heat exchangers. Through this structure, the integration of the air conditioning refrigerant circuit and the battery thermal management circuit reduces system complexity and cost, while also reducing space requirements and maintenance costs.

The air conditioning refrigerant circuit dynamically adjusts the refrigerant distribution to regulate the heat exchange distribution between the air conditioning refrigerant circuit and the battery thermal management circuit. The battery thermal management circuit includes a phase change thermal storage unit connected in parallel with the plate heat exchanger, releasing stored heat / cold energy during charging and discharging intervals, reducing the frequent start-stop of the compressor and PTC heater.

This invention discloses a method for detecting the operating status of a motion module driven by a stepper motor. The method includes the following steps: 1) Mounting an encoder disk with multiple detection holes onto the stepper motor shaft; 2) Installing a displacement sensor on the frame corresponding to the movement trajectory line of the detection holes. When a detection hole is detected, the sensor outputs a high-level signal and sends it to the motion module operating status detection unit; 3) The stepper motor controller sends STEP, DIR, and EN signals to the motion module operating status detection unit; 4) The motion module operating status detection unit sends the received signals to the stepper motor driver to drive the stepper motor; 5) If the motion module operating status detection unit detects no high or low level change in the displacement sensor output signal within one detection cycle, it determines that the motion module is operating abnormally, cuts off the STEP signal of the stepper motor driver, and the stepper motor stops running. This invention improves the accuracy of motion module operating status detection and the reliability of module operation.
