Lead storage battery is a common storage battery, usually used in automobiles, UPS power supply and other fields. However, it will also be affected by temperature during use, especially in high or low temperature environments, the chemical reaction rate inside the battery will change, which in turn will affect the performance and life of the battery. Therefore, in order to ensure that lead-acid batteries can work normally in various extreme environments, high-low temperature resistance tests are required. By simulating different temperature conditions, it is possible to test the charge and discharge performance, safety and reliability performance of lead-acid batteries at high-low temperatures, so as to evaluate their applicability and reliability in various application scenarios, and provide guidance for product development and production Provide reference and guarantee.
experiment procedure:
Put the lead-acid battery to be tested into the high-low Temperature Test Chamber, and set the temperature range and temperature change rate of the Test Chamber.
Raise the temperature of the Test Chamber to the preset high temperature value and keep it for a period of time (such as 4 hours), and observe whether the performance and state of the battery change.
Reduce the temperature of the Test Chamber to the preset low temperature value and keep it for a period of time (such as 4 hours), and observe whether the performance and state of the battery change.
Return the temperature of the Test Chamber to room temperature and keep it for a period of time (such as 1 hour), and observe whether the performance and state of the battery return to normal.
If it is necessary to further evaluate the durability and reliability of the lead-acid battery, the above steps can be repeated until the required test results are achieved.
In order to ensure the accuracy and reliability of the test results, it is necessary to select a high-low Temperature Test Chamber that meets international standards and conduct tests in accordance with standard test procedures. At the same time, sufficient analysis and evaluation of the test data is required to determine whether the performance and reliability of the lead-acid battery meet the requirements.
