Problems solved by technology

[0006] These systems are relatively heavy (refrigeration unit 300kg, generator 65kg), expensive (e.g. 5000 Euros), bulky and lack controls to optimize overall truck efficiency (e.g. separate diesel unit for generating power for the refrigerator consumption about 3l / h)
Moreover, these known systems can emit relatively large amounts of greenhouse gases and other pollutants

Embodiment Construction

[0041] In the present application, the same or corresponding features are marked with the same or corresponding reference numerals.

[0042] figure 1 A portion of a hybrid vehicle is schematically depicted. The construction of a hybrid vehicle is likewise known to the skilled person and therefore only a general description is given. Such a vehicle includes a hybrid powertrain (power drive train) comprising an engine E and an electric motor EMG, which can be connected to the wheels to provide torque to the wheels independently of each other or simultaneously. Arrow X indicates the flow of torque energy. Also, a battery (battery) B is provided to supply electric power. Charging the battery can be accomplished in a number of ways. For example, the powertrain may be in a charging state where the electric motor EMG acts as a generator and is driven by the engine to charge the accumulator / battery B (at figure 1 The resulting energy path is indicated by arrow Y1 in ). For examp...

Abstract

Vehicle system, comprising: -a hybrid powertrain (E, EMG, B) to drive the vehicle system and configured to generate electric energy; and - at least one electrically operable refrigerator unit (R) configured to cool at least one storage compartment of the system; wherein the refrigerator unit (R) is powered by electric energy generated by the hybrid powertrain.

Description

technical field [0001] The present invention provides a novel vehicle system. Background technique [0002] It is known to mount refrigeration systems for transport trailers on the trailer itself, which refrigeration systems usually include a vapor-compression system. These systems are typically powered by an independent 3-phase power supply, or by an engine-driven compressor, specifically, by one of the following three methods (1-3): [0003] 1) Apply a split 3-phase generator connected to the existing truck powertrain, e.g. engine drive pulley; external connection to the power grid can be used for nighttime cooling; the generator has approx. 15-20kVA power; [0004] 2) Application of a compressor driven directly by the internal combustion engine, possibly with an additional electrical connection for night cooling; and [0005] 3) Apply self-excited generator set, including engine and 3-phase generator. [0006] These systems are relatively heavy (refrigeration unit 300...
