Abstract
According to one embodiment, a BBU includes an array of battery cells, a DC/DC converter coupled to the battery cells, and a first switch logic coupled to the battery cells and the DC/DC converter. The first switch logic is configured to switch the BBU to operate between a first mode and a second mode. When operating in the first mode, the first switch logic causes the output voltage of the DC/DC converter to be provided to an external load. When operating in the second mode, the first switch logic causes the output voltage of the DC/DC converter to be coupled to an internal load for the purpose of determining the health of the battery cells.
