Below is an introduction to the application scenarios of Qinzhuo brand's walk-in constant temperature and humidity laboratory in the battery industry:

1、 Preparation before testing

Sample installation: The battery pack is smoothly moved into the laboratory work area by lifting or transferring the vehicle, and fixed on a dedicated testing fixture. Connect the external charge and discharge testing system and voltage/temperature collection harness (the harness needs to be led out through the dedicated lead hole on the room wall), ensuring that the wiring is firm and insulated.

Equipment settings: Set the temperature curve program for this test on the control panel, including the target temperature (such as -40 ° C to+60 ° C), heating and cooling rate (such as 1 ° C/min or 5 ° C/min), constant temperature time, cycle times, etc. Set up comprehensive safety alarm parameters (such as temperature exceeding limit, abnormal sample temperature, etc.).

2、 Test execution (common test items)

High and low temperature cycling test:

The program controls the laboratory temperature to cycle between a set high temperature (such as+60 ° C) and low temperature (such as -40 ° C).

The battery pack may undergo charge and discharge cycles (performed by an external system) during the constant temperature stage to verify its capacity, energy efficiency, charge and discharge characteristics, and cycle life at different temperatures.

Monitor the temperature and voltage changes of key points on the surface and inside the battery pack, observe their consistency and the effectiveness of the temperature control system (if any).

High temperature aging/storage testing:

Maintain the laboratory temperature at a consistently high level (such as 45 ° C or 55 ° C).

The battery pack may be in a fully charged static state or a low rate float charging state, and its capacity degradation, self discharge rate, and material aging under long-term high temperature should be evaluated.

Low temperature performance test:

Maintain the laboratory temperature at an extremely low level (such as -30 ° C or -40 ° C).

Conduct a discharge performance test on the battery pack to verify whether its available capacity, voltage platform, and power output capability at low temperatures meet the requirements.

Temperature shock test (if the device supports rapid temperature change):

Transform the battery pack between high and extremely low temperatures in a very short period of time, and assess its mechanical stress, sealing changes, and electrical performance stability caused by drastic temperature changes.

3、 Post test analysis

Data collection and analysis: Record the laboratory environment temperature, battery pack voltage, current, temperature and other data throughout the process. After the test is completed, analyze the data and evaluate whether the performance indicators of the battery pack (such as capacity retention rate and energy efficiency) meet the standards.

Sample inspection: Remove the battery pack for visual inspection (for deformation, cracks, leaks), disassembly inspection (for internal structural integrity, insulation condition), and safety testing (insulation resistance).

The advantages of Qinzhuo's walk-in high and low temperature laboratory equipment are reflected in:

Uniformity: Efficient air duct design ensures uniform temperature in the workspace and ensures testing consistency.

Stability: Precise temperature control, minimal fluctuations, providing a reliable environment for long-term testing.

Safety: It has multiple protections (overheating, overload, leakage, etc.), and the laboratory itself has good explosion-proof and ventilation design, providing additional safety protection for flammable battery testing.

Programmable: Flexible setting of complex temperature curves, automated operation, and reduced human error.

In summary, the Qinzhuo walk-in constant temperature and humidity laboratory systematically verifies the environmental adaptability, reliability, and safety boundaries of battery packs by simulating harsh temperature environments. It is an important key equipment in battery research and quality control.
