Abstract:
1. A method of operating a power management system, comprising: receiving a battery test command by control and access logic positioned on a power supply and battery charger board, the battery test command from a user interface on a remote device; controlling, by the control and access logic, a switching unit located on the power supply and charger board to switch an external load from an alternating current to direct current (AC-to-DC) power supply on the power supply and charger board to battery backup in response to the battery test command to initiate a battery discharge test; monitoring, by the control and access logic, voltage and discharge current of the battery; determining, by the control and access logic, that the battery has reached a threshold capacity due to battery discharge; terminating the battery discharge test by the control and access logic in response to determining that the battery has reached the threshold capacity; and switching, by the control and access logic, the external load back to the AC-to-DC power supply and off of the battery backup.
