This paper provides a preliminary battery assessment mechanism to address the hypothetical ECO-America EV Challenge. Several battery parameters are discussed in relation to pack needs, in addition to vehicle and environmental considerations. An evaluation method is provided, with a vision based on success and a metric for battery evaluation for the ECO-America Challenge. Five in-house testing procedures are also provided to ensure battery pack conformance and functionality. Finally, five scenarios are discussed that would cause the current evaluation method and metric to be revised.

Abstract:This article reviews the current state of railway engineering with a focus on the steady development of conventional technology that has led to the 575 km/h run of the French TGV train in 2007. Several key engineering areas are explored and predictions made for future technological developments in vehicle and track design including active suspension, improved aerodynamic performance, and novel track systems such as slab track. Non-conventional technologies such as magnetic levitation are discussed but the conclusion arrived at is that considerable improvements are still possible through optimization and incremental development of conventional engineering solutions and that, in the short to medium term, implementation of radically novel systems is less likely.

Development of a tilting system for electric multiple unit to speed up on conventional lines

An advanced tilting system for KTT (Korean Tilting Train) was developed and a performance test of the system has been completed. KTT has been constructed to speed up and promise a significant enhancement in service quality on a conventional line. KTT is an electric multiple unit composed of 6 cars running at the design speed of 200 km/h. The tilting system is the core technology of KTT and combined with the conventional bogie system. It has a self-steering mechanism and a swing link. The self-steering mechanism of Z-bar type is free to rotate on the curve and stable to run on a straight line. The swing link mechanism of the bolster enables the carbody to tilt up to 8°. A tilting control system detects a curve with sensors and commands the electro-mechanical actuators to move the bolster through the computer network system. GPS collaborates with the tilting system to perceive the curve previously and enables gradual tilting so as not to violate passenger comfort. The performance of the tilting system has been verified by a trial test running of KTT on a commercial conventional line. The tilting system is ready for commercial use.
