1. A method for operating a refrigeration system having a refrigeration unit for providing temperature conditioned air to a temperature controlled space, an engine and an electric generation device, the method comprising: providing a battery system having a least one battery unit supplying electric power; and during a first cooling demand mode, operating the engine to drive the electric generation device for supplying electric power and simultaneously employing the battery system for supplying electric power, such that both the electric generation device and the battery system jointly power (i) a compression device drive motor and (ii) at least one of a refrigerant heat rejection heat exchanger fan drive motor, a refrigerant heat absorption heat exchanger fan drive motor and an electric heater; during a second cooling demand mode, operating the engine to drive the electric generation device to power the compression device drive motor and operating the battery system to power at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and the electric heater; during a third cooling demand mode, operating the engine to drive the electric generation device to power (i) the compression device drive motor and (ii) at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and also charge the battery system; and during a fourth cooling demand mode, shutting off the engine and operating the battery system to power at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and the electric heater; wherein employing the battery system during the fourth cooling demand mode comprises selectively powering the refrigerant heat absorption heat exchanger fan drive motor for selected periods of time and at selected intervals. 2. The method as set forth in claim 1 further comprising: providing a battery charger in operational association with the battery system; andduring a period of shutdown of the engine, selectively employing an external power source for powering the battery charger to charge the battery system. 3. The method as set forth in claim 2 further comprising: providing a standby power grid connection for connecting to a supply power grid; andduring a period of shutdown of the engine, selectively powering the battery charger to charge the battery system with power supplied from the supply power grid through the standby power grid connection. 4. The method as set forth in claim 1 further comprising employing the battery system to power the refrigerant heat rejection heat exchanger fan motor and the refrigerant heat absorption heat exchanger fan motor. 5. The method as set forth in claim 1 wherein the first cooling demand mode comprises a temperature pulldown mode wherein the refrigeration unit is operated to reduce a temperature within the temperature controlled space to a set-point temperature. 6. The method as set forth in claim 1 wherein a second cooling demand mode comprises a temperature control mode wherein the refrigeration unit is operated to maintain a temperature within the temperature controlled space within a specified range of a set-point temperature, the second cooling demand lower than the first cooling demand. 7. The method as recited in claim 1 wherein the temperature controlled space comprises the perishable cargo hold of a truck, trailer, intermodal container or other transport container. 8. A transport refrigeration system having a refrigeration unit for providing temperature conditioned air to a cargo storage space of a truck, trailer, intermodal container or other transport container, the refrigeration unit having a refrigerant compression device, a refrigerant heat rejection heat exchanger and an associated fan, a refrigerant heat absorption heat exchanger and an associated fan, and a plurality of power demand loads including a compression device drive motor, a refrigerant heat rejection heat exchanger fan drive motor, a refrigerant heat absorption heat exchanger fan drive motor and an electric heater, the transport refrigeration system having an electric generating device and an engine for driving the electric generating device, the transport refrigeration system further comprising: a controller operatively associated with the refrigeration unit, the controller operative to selectively operate the refrigeration unit in multiple modes, the modes comprising: a first cooling demand mode, operating the engine to drive the electric generation device for supplying electric power and simultaneously employing the battery system for supplying electric power, such that both the electric generation device and the battery system jointly power (i) the compression device drive motor and (ii) at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and the electric heater; a second cooling demand mode, operating the engine to drive the electric generation device to power the compression device drive motor and operating the battery system to power at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and the electric heater; a third cooling demand mode, operating the engine to drive the electric generation device to power the (i) the compression device drive motor and (ii) at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and also charge the battery system; and a fourth cooling demand mode, shutting off the engine and operating the battery system to power at least one of the refrigerant heat rejection heat exchanger fan drive motor, the refrigerant heat absorption heat exchanger fan drive motor and the electric heater; wherein during the fourth cooling demand mode the controller employs the battery system to selectively power the refrigerant heat absorption heat exchanger fan drive motor for selected periods of time and at selected intervals. 9. The transport refrigeration system as set forth in claim 8 wherein the controller is further operative to operate the engine to drive the electric generation device to power the compression device drive motor and simultaneously employ the battery system to power the refrigerant heat rejection heat exchanger fan motor and the refrigerant heat absorption heat exchanger fan motor.
