Civitas Forum 2015 • 8 October 2015 • Ljubljana • S.Misanovic
Our choice of concept charging E.bus
Opportune charge on Terminus via pantograph
Storage using super capacitors or Battery
(Advantage for UC)
• Acceptable charge time
• Ability to connect to the trolleybus and tram contact
network ( DC), or public distribution electric grid (AC)
• E.bus can work all day (especially important in
summer when air conditioning is used as a large
consumer)
•Principle: Electro static
•High power
•High efficiency 92-98%

CONSLUSIONS

Introduction of fully electric buses into regular exploitation presents a significant
qualitative move forward in the public city transportation in Belgrade.
 The presented analysis showed that exploitation of electric buses in Belgrade, offered
better energy and economic effects of the application compared to the trolleys and
especially to the diesel buses
 Fully electric buses, proven as ecologically “clean” and energetically efficient vehicles,
during the next period, will give growing contribution to sustainable development of the
cities, with the ultimate goal that by the 2050 year they will be the primary system of the
public transportation .
