Hybrid power conversion system for a refrigerated transport vehicle and method

A method of operating an air conditioned system of a transport vehicle comprising:

• providing electrical power to at least one of a plurality of refrigeration components with a battery, the battery configured to output a total DC power;
• providing supplemental electrical power with at least one supplemental power source, the electrical power provided by at least one supplemental power source combined by a charger and routed to the battery to be part of the total DC power, wherein the at least one supplemental power source comprises a fuel cell pack;
• converting, by a power converter, the total DC power to a total AC power;
• and
• routing the total AC power to the at least one refrigeration component;
• wherein the power required for all operations of the plurality of refrigeration components does not require power provided by a refrigeration system engine.

A hybrid power conversion system for an air conditioned transport vehicle comprising:

• a plurality of refrigeration components for heating and/or cooling a refrigerated volume;
• a battery storing electrical power to be provided to at least one of the plurality of refrigeration components;
• at least two supplemental power sources providing electrical power;
• a charger to combine the electrical power provided by the at least two supplemental power sources and provide a combined DC output to the battery to provide a total available DC power for the refrigeration components;
• and
• a power converter converting the total available DC power to a total AC power, the total AC power provided to at least one of the plurality of refrigeration components;
• wherein the battery provides all the electrical power required for all operations of the at least one of the plurality of refrigeration components and the hybrid power conversion system does not include a refrigeration system engine.
