Battery module High and low temperature coolant test equipment is used to simulate and verify the performance of power batteries under different temperature conditions and the effectiveness of thermal management systems. When using this device, you need to pay attention to the following points:

　　1. Preparations: Ensure that the tester is properly grounded, the power supply is stable, and all pipe connections are secured before the battery module is tested for high and low temperature liquid cooling. According to the specification parameters of the module to be tested, the key parameters such as the operating temperature range, circulation mode and flow rate of the test equipment are set accurately.

　　2. Coolant selection and treatment: In the battery module high and low temperature coolant test equipment, it is necessary to use a coolant that meets the standard, usually antifreeze or thermal oil, to ensure that it is compatible with the battery material and has good thermal conductivity. Replace or filter the coolant regularly to maintain its cleanliness and effective thermal conductivity.

　　3. Safety measures: In order to ensure the reliability of the battery module coolant test equipment during operation, it must have protection functions such as overheating, low temperature and abnormal pressure, and be equipped with an alarm system.

　　4. Correct operation: The operator of the battery module high and low temperature coolant test equipment needs to be familiar with the temperature control system and accurately set the test process, including the heating rate, cooling rate and target temperature.

　　5. Data recording and analysis: Record and analyze experimental data, evaluate the performance parameters of the battery module under different temperature conditions (such as capacity retention rate, internal resistance changes, etc.), and the efficiency of the thermal management system.

　　6. Equipment maintenance: It is necessary to carry out regular equipment maintenance, including cleaning heat exchangers, checking pump operation, lubricating key components, etc. Periodically check according to the maintenance manual provided by the manufacturer to discover and handle potential faults in a timely manner.

　　When using the battery module high and low temperature coolant test equipment, the operating procedures must be strictly followed to ensure the safety and accuracy of the experiment. At the same time, test schemes and data analysis methods are constantly optimized according to actual needs to obtain real and effective battery performance data.
