Recuperative Hybrid Trains using Batteries in an intermodal Container

Abstract

The present invention relates generally to hybrid versions of diesel-electric locomotives and improves the previous art by placing such batteries in standard intermodal containers which can easily be moved by readily available cranes built for the purpose of moving freight containers. The containers housing the batteries are standardized, so that different operators can use them by way of purchase or rental. The invention produces the following advantages. (1) After a descent from high altitudes, a full battery unit can be removed from a train and put in storage to reduce the weight of the train should no extra power be needed for the next leg of the journey. On particular long descents, full battery units can be replaced by empty ones several times to enable further energy recovery as the train continues its way down the mountain. (2) Conversely, a train heading for the mountains can be loaded with one or more full battery containers from storage to reduce the use of fossil fuels during the ascent and, if need be, receive replacement units on the way should the original set not last long enough to reach the high point. (3) Different configurations become possible such as two containers, one on top of the other, to accommodate different requirements. (4) The commercial trade of battery containers, made possible through standardization, will create a market for energy which will result in its most efficient use.

1 . The recuperative batteries of a hybrid diesel-electric train are installed not on the locomotive or a battery tender, but in a standard intermodal container in which also are installed a ventilation system to prevent overheating or the accumulation of unwanted fumes as well as cables with plugs to connect the container's batteries to the power grid and information network of the train and/or chassis if a chassis with motors and recuperative brakes is used. 
     
     
         2 . The whole container, which houses the batteries, is moved to and from storage areas or other trains through the use of container cranes available at most freight stations. The chassis itself remains part of the train during this process. 
     
     
         3 . The battery containers as described above are standardized so that different operators can use them by way of purchase or rental.
