Get Trams On Batteries

On-board energy storage systems, such as batteries, enable light rail vehicles to operate without overhead wires in key areas of sensitivity.

Traction Battery Trams Traction batteries (or electric vehicle batteries; EVBs) are batteries that are used for the primary or secondary propulsion of electric vehicles.

The world's first experimental electric tramway was built by Ukrainian inventor Fyodor Pirotsky near St Petersburg, Russian Empire, in 1875. The first commercially successful electric tram line operated in Lichterfelde near Berlin, Germany, in 1881.

Today, most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used.

Trams are significantly heavier than buses and require more energy to get moving from a standstill. A tram consumes 0.047 kWh/km per passenger (8).

traction motors mounted 'wheelbarrow' fashion supported partly by the axle and partly by spring frames on the truck; brakes operated by hand, compressed air or electricity; series-parallel controllers switching the traction current through resistance grids; and. earth return current through the wheels to the rails.

Trams are also predictable, when a table says that there will be a tram in 5 minutes, there'll be a tram in 5 minutes, no wait. Some disadvantages include the fact that they are bound to their rails, if there is an obstacle on the track or if the track is blocked the tram just can't move.

Over the years various refinements have been made, such as replacement of series-parallel controllers with modern solid state control systems, and the substitution of trolley poles with pantographs. However, in the majority of tramways the electricity supply is still between 600 and 750 volts DC [1].
