Abstract
A transport refrigeration system is provided. The refrigeration transportation system comprising: a refrigerated cargo space; a refrigeration unit in operative association with the refrigerated cargo space, the refrigeration unit providing conditioned air to the refrigerated cargo space; a battery system configured to power the refrigeration unit; and an auxiliary power unit configured to charge the battery system when the power level of the battery system is equal to or below a first selected power level.
Claims20
A transport refrigeration system comprising:
- a refrigerated cargo space;
- a refrigeration unit in operative association with the refrigerated cargo space, the refrigeration unit providing conditioned air to the refrigerated cargo space;
- a battery system configured to power the refrigeration unit;
- and
- an auxiliary power unit configured to charge the battery system when the power level of the battery system is equal to or below a first selected power level.
A method of operating a transport refrigeration system, the method comprising:
- providing conditioned air to a refrigerated cargo space using a refrigeration unit;
- powering the refrigeration unit using a battery system;
- and
- charging the battery system using an auxiliary power unit when the power level of the battery system is equal to or below a first selected power level.
A controller for a refrigeration unit of a transport refrigeration system comprising:
- a processor;
- a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
- providing conditioned air to a refrigerated cargo space using a refrigeration unit;
- powering the refrigeration unit using a battery system;
- and
- charging the battery system using an auxiliary power unit when the power level of the battery system is equal to or below a first selected power level.
