ENERGY BASED BATTERY BACKUP UNIT TESTING

摘要

Several embodiments perform battery backup unit (BBU) degradation testing. For example, a BBU testing system can be coupled to or part of a BBU. The BBU testing system can discharge the BBU by engaging a variable load to the BBU. The BBU testing system can monitor a discharge energy consumption over time as the BBU discharges until the discharge energy consumption reaches a specified amount of energy. The BBU testing system can determine a discharge time for the discharge energy consumption to reach the specified amount of energy. The BBU testing system can then compute a degradation state of the BBU based on the discharge time.
