1. A transport refrigeration system (TRS), comprising:
- an undersized main power source that is only capable of generating up to but not more than a first maximum threshold power;
a secondary power source that is only capable of generating up to but not more than a second maximum threshold power that is lower than an amount of power sufficient to run the TRS at a full cooling capacity;
a tertiary power source; and
a controller,wherein the TRS requires more than the first maximum threshold power to operate at a full cooling capacity,wherein the TRS requires more than the second maximum threshold power to operate at the full cooling capacity,wherein the TRS requires less than a total of the first maximum threshold power and the second maximum threshold power to operate at the full cooling capacity,wherein the undersized main power source and the secondary power source are configured to cooperate with one another to supply a supply power to the TRS at the full cooling capacity, andwherein the undersized main power source supplies a first amount of the supply power to the TRS, the first amount of the supply power being lower than an amount of power required to allow the TRS to operate at the full cooling capacity,wherein the secondary power source supplies a second amount of the supply power to the TRS, the second amount of the supply power being lower than the amount of power required to allow the TRS to operate at the full cooling capacity, to supplement the undersized main power source in order to allow the TRS to operate at the full cooling capacity,wherein the controller determines whether a maximum current is drawn from the secondary power source, andwherein the tertiary power source supplies power to the TRS to supplement the undersized main power source to allow the TRS to operate at the full cooling capacity when the maximum current is drawn from the secondary power source.

Abstract
Systems and methods are directed to providing power to a transport refrigeration system (TRS) using an undersized main power source in combination with a secondary power source. The systems and methods allow the undersized main power source to be used with a TRS that requires a power more than a maximum threshold power of the undersized main power source to operate at a full cooling capacity. The secondary power supplements the undersized main power to allow the TRS to operate at the full cooling capacity. Optionally, a tertiary power source can supplement the undersized main power source, or the undersized main and secondary power sources to run the TRS.

8. A method of supplying power to a transport refrigeration system (TRS), the method comprising:
-
supplying a first amount of power to the TRS from an undersized main power source, the first amount of power being lower than an amount of power required to allow the TRS to operate at a full cooling capacity; supplying a second amount of power to the TRS from a secondary power source, the second amount of power being lower than the amount of power required to allow the TRS to operate at the full cooling capacity, the secondary power source supplementing the undersized main power source to allow the TRS to operate at the full cooling capacity; determining whether a maximum current is drawn from the secondary power source, and supplying power to the TRS from a tertiary power source to supplement the undersized main power source to allow the TRS to operate at the full cooling capacity when the maximum current is drawn from the secondary power source. - View Dependent Claims (9, 11, 13, 14, 15, 16, 17, 18, 19)
