The possibility of using autonomous motion of an electric vehicle (EV) in parts of its route that lack a source of electric power is considered. In this case, supply of energy to the EV traction...

During operation of a hybrid powertrain with intermediate buffer energy storage, an inadmissible decrease in the amount of of stored energy may occur. The parameters of hybrid powertrain elements...

Battery-electric locomotives with lithium-polymer storage batteries are proposed for shunting operations on electrified railroad lines considering experience of energy storage devices applications. Main parameters of traction drive are calculated and its functional scheme is shown in the article. Advantages of battery-electric over diesel locomotives are discussed, estimated fuel economy is shown.

The method of evaluation of energy recuperation efficiency is proposed. This method based on the research of trolleybus power consumption in real operating conditions. It was determined that the part of recuperation energy is about 18% from the energy utilized in traction mode. Also it was estimated that the probability of energy recuperation is about 90% in case of fully paralleled bilateral feeding of traction network and the presence of 14 trolleybuses at the feeding area.

Capacity of an energy storage device for hybrid electric bus is calculated based on experimentally obtained drive cycle. Statistical analysis of experimental drive cycle is performed. Possible areas of adaptation of obtained results are discussed.

Modern trends of electrical transport sector’s development represent a set of technological innovations from various fields of science. A transition to electric traction drive currently is one of the topical and implemented directions at the global market. There are different of types of transport electrifying and the most common is using batteries which technical and economic characteristics begin to satisfy the world's automakers. Another perspective way is the conversion of natural gas like hydrogen into the electricity for the movement needs. The process of transition to a fully electric traction drive requires an integrated approach and cannot be considered without taking into account power sources limitations, changes in the infrastructure of cities, climatic features, environmental security and economic feasibility. In this context, it makes sense to consider the united power plant consisted of batteries and hydrogen fuel converters because each of them has pros and cons if consider them like a divided power sources. This approach will increase the variability of suitable technological innovations while vehicles for different operating conditions designing.
