Figure 1 The diagram shows a flowchart of a dynamic environment testing method for an energy storage system according to an embodiment of this application. The method includes at least the following steps S110 to S120:

[0035] Step S110: Based on the pre-constructed multi-parameter coupled environmental field, environmental parameters are obtained by adjustment, wherein the multi-parameter coupled environmental field includes at least temperature, humidity, air pressure, electrical disturbance and mechanical stress.

[0036] A multi-parameter coupled environmental field, including temperature, humidity, air pressure, electrical disturbance, and mechanical stress, is constructed, and environmental parameters are obtained by controlling the multi-parameter coupled environmental field.

[0037] Specifically, a four-dimensional environmental controller is adopted, which may include a temperature and humidity control module, an air pressure control module, an electrical disturbance module, and a mechanical stress module to achieve four-dimensional coupled control of temperature and humidity, air pressure, electrical and mechanical stress.

[0038] The temperature and humidity control module utilizes a two-stage compression variable frequency liquid chiller unit for temperature control, with continuously adjustable cooling capacity from 0 to 200 kW and a temperature control range of -40℃ to 85℃. The slope is adjustable. Hot and cold water pipes can be connected in parallel to achieve rapid switching of ambient temperature. Humidity control employs a combination of an atomizer and a drying system. The temperature control logic uses a feedforward-PID composite control, combining load power prediction and real-time temperature feedback. The specific steps include: Step 1: Feedforward compensation, predicting temperature changes based on load power; Step 2: kW→℃ compensation coefficient (measured and calibrated); Step 3: PID feedback, dynamically adjusting the compressor frequency with a proportional coefficient changing in real time; Step 4: Temperature compensation for the low-temperature zone.

[0039] For humidity control logic, dew point closed-loop control can be adopted. The specific steps include: Step 1: Determine whether the dew point deviation is greater than 0.5℃ through the sensor; Step 2: If yes, start atomization / drying, otherwise maintain the current state; The starting atomization amount is kp·ΔT+ki·∫ΔT, and the drying system is triggered to make the humidity >80%; where kp·ΔT is the proportional term, which adjusts the atomization amount in real time according to the current dew point deviation (ΔT=T target dew point-T actual dew point), and ki·∫ΔT is the integral term, which is used to accumulate historical dew point deviations and eliminate steady-state errors.

[0040] The air pressure control module uses a precision pressure regulating valve for control, and the control logic is as follows: P 实际 =P 设定 +K·(d(ΔP) / dt)(K=0.5kPa / s).
