A backup power supply system and a method for providing power to an electrical load are provided. The system includes at least one supercapacitor, a battery and a power supply controller. The controller is configured to determine whether an output of a primary power supply for the load meets a first predetermined condition, determine, when the output of the primary power supply does not meet the first predetermined condition, a level of current required by the load, provide current to the load from the supercapacitor if the level of current required by the load meets a second predetermined condition, and, provide current to the load from the battery if the level of current required by the load does not meet the second predetermined condition until an output of the battery meets a third predetermined condition and thereafter provide current to the load from the supercapacitor.
