Part 2. Principles of battery load testing
Understanding the fundamentals and factors that affect the testing process is essential for conducting actual battery load tests.
Load test method
The load test method involves subjecting the battery to a known load for a specified period of time while monitoring its voltage and performance. The following steps outline a typical load test process:
1，Prepare the battery for testing by making sure it is fully charged and at the recommended temperature.
2，2. Connect the battery to a load test device that exerts a controlled load.
3，Loads are applied for a predetermined duration, usually based on battery specifications or industry standards
4，Monitor battery voltage and performance throughout the test.
5，Analyze test results to assess battery condition and determine any necessary action.
Factors that affect a load test：
Several factors affect the accuracy and reliability of the battery load test. The following factors must be considered to obtain accurate results
Battery temperature
Battery performance varies greatly with temperature. Therefore, it is important to perform load tests at recommended temperature conditions to obtain reliable and consistent results
The applied load
The load applied during testing should reflect expected actual usage. Using the appropriate load level may result in accurate results and an incomplete assessment of battery performance
Test duration
Load test duration should meet battery specifications or industry standards. Insufficient test time may not detect specific battery problems, and prolonged testing may damage the battery
Equipment calibration
Technicians regularly calibrate load test equipment to ensure accurate measurements. Correct calibration helps to maintain the reliability and consistency of test results.
