Abstract
Hybrid power systems include an internal combustion engine and a motor/generator connectable with the engine. A reefer unit is configured to receive power from the motor/generator via a reefer power system that includes an export power inverter and an energy storage device.
Claims19
A hybrid reefer system, comprising:
- a hybrid power system including an internal combustion engine and a motor/generator connectable with the internal combustion engine;
- a reefer unit;
- and
- a reefer power system connecting the motor/generator with the reefer unit, the reefer power system including with at least an export power inverter to receive unregulated input power from the motor/generator and provide regulated output power to the reefer unit, the reefer power system further including a battery and a DC/AC inverter, wherein the DC/AC inverter connects the reefer unit to each of the battery and the export power inverter.

A hybrid reefer system, comprising:
- a hybrid power system including an internal combustion engine and a motor/generator connectable with the internal combustion engine;
- a reefer unit;
- and
- a reefer power system connecting the motor/generator with the reefer unit, the reefer power system including with at least an export power inverter to receive unregulated input power from the motor/generator and provide regulated output power to the reefer unit, wherein the reefer power system includes:
- a second internal combustion engine;
- a second motor/generator connectable to the second internal combustion engine;
- a second export power inverter connected to receive power from the second motor/generator and supply power to the reefer unit;
- and
- wherein reefer power system includes a battery connected to supply power to the reefer unit, the battery also connected to the first motor/generator through the export power inverter to receive power from the first motor/generator.

A hybrid reefer system, comprising:
- a hybrid power system including an internal combustion engine and a motor/generator connectable with the internal combustion engine;
- a reefer unit;
- and
- a reefer power system connecting the motor/generator with the reefer unit with at least an export power inverter to receive unregulated input power from the motor/generator and provide regulated output power to the reefer unit, wherein the reefer power system includes a generator and a reefer engine, the generator being connected between the reefer unit and the reefer engine.
1 more element
A vehicle system, comprising:
- a first vehicle including a hybrid power system and a first electrical power storage device;
- and
- a second vehicle mounted to the first vehicle, the second vehicle including a second electrical power storage device that is electrically connected to the first electrical power storage device, and the second electrical power storage device is disconnected from the first electrical power storage device and provides power for propulsion of the second vehicle with the second vehicle dismounted from the first vehicle, wherein the first and second electrical power storage devices share electrical power for operation of the first vehicle with the second vehicle mounted to the first vehicle, and wherein the first electrical power storage device includes a higher power performance characteristic than the second electrical power storage device and the second electrical power storage device includes a higher energy performance characteristic than the first electrical power storage device.
