Hybridized fuel cell transport refrigeration units

A method of operating a transport refrigeration system, the method comprising:

• providing electricity from a fuel cell to a transport refrigeration unit, the transport refrigeration unit configured to provide conditioned air to a refrigerated cargo space of a transport container;
• powering the transport refrigeration unit using the electricity from the fuel cell;
• detecting a condition of the transport refrigeration unit that requires supplemental electricity, wherein the condition of the transport refrigeration unit that requires supplemental electricity is at least one of a low load condition, a max load condition, or a rapid ramp condition;
• providing supplemental electricity from one or more supplemental power sources to the transport refrigeration unit during the condition of the transport refrigeration unit that requires supplemental electricity;
• and
• powering the transport refrigeration unit using at least the supplemental electricity from the one or more supplemental power sources during the condition of the transport refrigeration unit that requires supplemental electricity.

A computer program product tangibly embodied on a non-transitory computer readable medium, the computer program product including instructions that, when executed by a processor, cause the processor to perform operations comprising:

• providing electricity from a fuel cell to a transport refrigeration unit, the transport refrigeration unit configured to provide conditioned air to a refrigerated cargo space of a transport container;
• powering the transport refrigeration unit using the electricity from the fuel cell;
• detecting a condition of the transport refrigeration unit that requires supplemental electricity, wherein the condition of the transport refrigeration unit that requires supplemental electricity is at least one of a low load condition, a max load condition, or a rapid ramp condition;
• providing supplemental electricity from one or more supplemental power sources to the transport refrigeration unit during the condition of the transport refrigeration unit that requires supplemental electricity;
• and
• powering the transport refrigeration unit using at least the supplemental electricity from the one or more supplemental power sources during the condition of the transport refrigeration unit that requires supplemental electricity.
