Opis:
The overall objective of the IDEAS project is to develop advanced packaging for power supply components and new generation memory systems applicable to Electric and ICE propelled vehicles, with paying attention to considering also the aspects that have not been addressed yet in the running ENIAC and ARTEMIS Automotive projects. A major challenge related to electronic devices in the automotive applications is the reliability of power supply systems which must be capable to assure the functionality of subsystems in all operating conditions, inclusive of ageing. The control systems, which rely on multicore microcontrollers and complex software architectures, require increasingly stringent constraints from the memory devices which need to be designed for very high bandwidth, speed and reliability. In the following thesis, a few aspects of the IDEAS project will be presented: a review of important factors that affect the reliability and life-cycle endurance of NAND flash memories, multispeed gear application in electric drives and its influence on the energy efficiency. The problem of electromagnetic compatibility of electronic devices will also be dealt with in the paper

Opis:
The article presents the methodology for light two-wheeled electric vehicle energy balance investigation using MAHA LPS 3000 chassis dynamometer. For this purpose, the laboratory tests, as well as the road tests, have been performed on the self-constructed light two-wheeled electric vehicle equipped with the 3 kW BLDC motor and the 100.8 V battery pack. The road test data have been used to set up the dynamometer parameters in order to simulate the real road drive taking into account, among others, the rolling resistances and the air drag coefficient. The overall energy consumption for the laboratory tests and the road conditions’ tests have been then compared for different vehicle speeds. In addition, based on the power and the torque characteristics measured on the MAHA chassis dynamometer, the efficiency of the vehicle electric drive system and the efficiency of the battery charging process have been calculated.

Opis:
At the beginning of the paper, the analysis of energy efficiency indicators for freight electric locomotive with asynchronous traction drive feeding from AC network under various operating conditions including when working with trains of various masses is made. The movement on different railway sections is considered. The graphs of locomotive’s speed, traction force, consumed power, and power for the traction obtained by on-board recorder are shown. In addition, the dependence of the locomotive's energy efficiency from the degree of using of its available traction capacity has been experimentally obtained, the greater is the using of the locomotive’s capacity, the greater will be its efficiency. On the basis of the performed analysis of energy efficiency indicators for various operating conditions, the proposals for their improvement are formulated. The algorithm ensuring the stabilization of the instantaneous value of efficiency at partial load to its nominal level at full load is presented. This algorithm is the implementation of Scalable Power Control Technology with respect to the problem of reducing electricity consumption for electric locomotive traction. The direct the experimental confirmation of energy consumption reduction for freight electric locomotive due to the application of our proposals (under the same operating conditions of the locomotive) is obtained.
