Diesel-electric vehicles with energy storage |

|
Modern energy storage devices permit the storage of braking energy on-board for use in the subsequent acceleration phase. This offers the possibility of an effective brake energy recovery in diesel-electric vehicles. Furthermore the peak demands on the diesel engines are reduced allowing for both downsizing of engine layout and better load management of diesel engines.

Storage systems for diesel-electric regional and suburban trains are an interesting option for energy efficiency. However, payback times for present storage technologies are critical, especially in regional operation with large distances between stops. This may improve in the future if scale effects can be realized in storage technologies. |
