A new battery— except for nickel-cadmium batteries— should be tested as soon as practical after installation and commissioning. This type of test is known as an acceptance test. The battery technologies and their applicable IEEE testing and maintenance standards are: 1. Vented lead-acid (VLA)— IEEE 450-2020.

AI Customer ServiceHow is the discharge rate determined? The battery manufacturer data sheet is required (See Table 1). This shows the available performance for the subject battery. Testing
AI Customer ServiceAlso known as load testing, or discharge testing, capacity testing is a dynamic test whereby a simulated load (in amperes or watts) is imposed on the battery system for a specified time. The discharge continues to a defined end-of-discharge (EOD) voltage, referencing a measured battery temperature taken at the start of the test.
The discharge rate to be used for the test has a direct impact on the resources and an appropriate balance between the duration, backup supply and testing equipment is desired to minimize the cost of the test. Understanding and using the discharge tables for each battery is paramount to obtaining accurate results.
Before determining a diagnostic from a battery capacity result and judging it only by the percentage, it is important to confirm the average cell temperature at the beginning, and if a correction factor was used or is required, then it needs to be compared to previous results.
The ratio between the resulting time and the expected time, with a temperature correction, defines the capacity of the battery in percentage. This method is the Time Adjusted capacity test and is the preferred method for tests longer than one hour.
When the test time reaches three hours, the battery voltage would be 105V for a capacity of 100%. Test results frequently result in a capacity of more than 100%, which is why it is important the test be run to the EOD voltage rather than terminating the test at 100% capacity.
By following these steps, BMS testing can be conducted effectively to ensure that the battery management system is safe, reliable, and performs optimally under all expected conditions. Main Positive Terminal Check: Measure the voltage at the main positive terminal of the battery management system.
