Embodiment Construction

[0012] figure 1 An exemplary hybrid energy system 10 is shown. Specifically, system 10 includes an engine 12 and a storage device 14 and may be configured to selectively supply energy to traction loads 16 and auxiliary loads 18 via a hub 20 . Energy concentrator 20 may selectively receive energy from engine 12 and / or traction load 16 and direct the received energy to storage device 14 , traction load 16 and / or auxiliary load 18 . System 10 may also include a controller 22 operable to control operation of engine 12 and storage device 14 and / or direct energy to one or more components of system 10 via energy concentrator 20 . System 10 may be operatively associated with machines such as locomotives, on-highway or off-highway vehicles, generator sets, and / or other work machines. It is contemplated that system 10 may include one or more additional and / or different components, such as a transmission device, drive train, electrical and / or hydraulic lines, and / or other components kn...

Abstract

A method and apparatus are disclosed for controlling a hybrid energy system (10) including a method (100, 200) of storing energy within a hybrid energy system. The hybrid energy system includes a traction load (16) and a first energy consuming system (18) configured to maintain a first criteria within a first operating range. The method includes receiving energy into the hybrid energy system fromthe traction load and distributing (110) a first energy to the first energy consuming system when the first criteria is within the first operating range.

Description

technical field [0001] The present invention relates to hybrid energy systems, and more particularly to methods and devices for controlling hybrid energy systems. Background technique [0002] Hybrid energy systems generally include an engine whose prime mover, such as a crankshaft, is mechanically decoupled from one or more loads, such as a motor vehicle traction load. The hybrid energy system also typically includes an energy storage device configured to store energy received from the engine during an engine overpower mode or the traction device during a vehicle dynamic braking mode. The engine and storage device are often electrically connected to the load, such as via a motor generator, allowing the engine to also operate as an energy source rather than a traditional drive mechanism, and allowing the storage device to recover energy regenerated from dynamic braking. The amount and frequency of regenerative energy is generally independent of, and often exceeds, the capac...
