The share of BEV and PHEV in total number of registered vehicles (%) 2011-2016
Dane BadawczeIn 2016, the highest percentage of electric vehicles among all passenger automobiles was recorded in Norway - about 28% (it should be noted that in 5 years the number of electric cars in this country increased from 5 thousand to 133 thousand). However, the remaining countries in the ranking note a much smaller share of sales of electric vehicles in...

Evaluation of the energy efficiency of electric vehicle drivetrains under urban operating conditions
PublikacjaIn electric vehicles, as in hybrids vehicles, a very important factor affecting the energy efficiency of the powertrain is the ability to use the regenerative braking energy. Depending on the settings available in electric vehicles, the driver can choose different modes of operation: switch off the regenerative braking mode altogether, select the intensity of regenerative braking, or leave the control system in automatic mode....

Requirements for Residual Current Devices Intended for Electric Vehicle Charging Systems
PublikacjaThe properties of residual current devices have been presented from the point of view of their ability to detect a specific shape of the residual current waveform. Moreover, the standard requirements relating to residual current protection used in electric vehicle charging installations have been pointed out. The operating characteristics of the IC-CPD and RDC-DD protections, which are intended for charging electric vehicles in...

Economic benefits of dynamic charging of electric buses
PublikacjaDiesel engines buses are still the most used type of buses. Electric buses provide promising green alternatives and a lot of advantages, but their main disadvantages are limited travel range and long charging time. This article is a presentation of innovative solution for charging of electric busses - Dynamic Charging (IMC). The modern IMC system in Solingen was presented. At the end of the article, a proposal was made to introduce...

Driving Performance Indicators of Electric Bus Driving Technique: Naturalistic Driving Data Multicriterial Analysis
PublikacjaThe issue of electric energy saving in public transport is becoming the key area of interest. By improving of driving techniques and the implementation of eco-driving, it is possible to save electric energy. Systems that help to decrease energy consumption and to reduce fuel emissions are becoming popular in vehicles powered by diesel engines. However, these methods have not yet gained popularity in electric vehicles. Therefore,...

Dynamic charging of electric buses
PublikacjaDespite the continuous development of electrochemical battery technology and the multitude of electric buses on offer, it is still not possible to exploit electric buses in urban transport on an all-day basis without the necessity of charging them. It is therefore necessary to build point-to-point contact charging stations or induction charging stations at the terminals. This results in substantial financial outlays connected with...

Storage electric multiple units on partially electrified suburban railway lines
PublikacjaThe paper presents possible environmental, energy and economical gains implied by replacing conventional traction vehicles with independent powered electric multiple units (IPEMU) on partially electrified suburban railways. IPEMUs can operate in two modes of power supply – using overhead catenary or onboard battery storage. Appropriate computer simulations were carried out in the Matlab program, indicating the parameters of storage...

Directions and Prospects for the Development of the Electric Car Market in Selected ASEAN Countries
PublikacjaThe purpose of this article is to present the current situation and evaluate the opportuni‐ ties for the development of the electric car market in selected Southeast Asian countries in the con‐ text of the current situation in the rest of the world. Currently, the electric car market is at an ad‐ vanced stage of development in regions such as Western Europe, the USA, and China. It should be noted, however, that the number of electric...

Energy savings by application of supercapacitor storage in trolleybus supplying station - analysis of experimental results
PublikacjaStorage devices can be divided into two groups: on-board energy storage devices, which are placed in the vehicles and off-board energy storage devices situated in traction substations or between them. Current research is focused mainly on two objectives. The first is to reduce the energy demand by introducing on-board energy storages in light electric vehicles like trams, trolleybuses or electrobuses. The latter is to provide a...
