How to relieve city electrotransport of wires?Krom of indisputable pluses city electrotransport has one fat minus - a contact network. This shortcoming electric buses are deprived. The silent and pure cars developed and manufactured by the Volvo company came to a route in the Swedish city the Gothenburg. Electrobuses resupply energy at final stops, spending for “gas station“ literally only a few minutes.
The “horned“ city transport can be met in many cities. Trolleybuses and trams proved perfectly, they do not pollute the city atmosphere, economically spend energy and money.
Despite obvious pluses, housing and communal services do not love trolleybuses from - for the fact that they need the contact power supply network. For this reason electrotransport is “expelled“ often from the central streets where the slightest jams threaten to stop already dense and slow steam of cars completely.
Whether city electrotransport without suspended on support and extensions of wires can manage? The Volvo company and the city authorities of the Gothenburg successfully look for problem solutions.
Cooperation of the Gothenburg and Volvo continues several years. In the beginning the car maker developed and released on a city route No. 55 seven hybrid the diesel - electric buses which transport passengers also today, as well as all other regular buses.
The first three hybrids which came out to city streets within experiment showed tremendous results. Consumption of diesel fuel decreased by 80%, the general economy of energy made 60%.
As it appeared, hybrid buses became only the first step to creation of city autonomous completely electric transport.
At first sight, it is simple to solve a problem, it is enough to equip buses with capacious rechargeable batteries. But the more energy the battery can reserve, the longer load it that means inevitable idle times of expensive cars and decrease in profitability.
Spring of 2014 the Volvo company declared intention to build on 55 - m a route in the Gothenburg the electric road urged to eliminate or to considerably reduce idle times of electrobuss at terminal stations, necessary for recharge of accumulators. Recently mass media reported about the end of construction and the beginning of trial operation of the city`s first electrified route.
Earlier the Volvo company informed that it plans to use directly during the movement of buses technology of wireless induction battery charging. Owners of the advanced smartphones are already familiar with the principles of its work. To include charging, they just put gadgets on the small platform connected to the socket.
It was planned that on a site of the street 300 - 500 meters long under a paving the wires inducing electric current in the bus receiver will be laid.
In practice business did not reach induction. Perhaps, it still ahead, but so far at final stops of a route 55 was constructed on fast charging station.
For connection to them buses as if usual suburban electric trains, lift current collectors on a roof. Time of a charge makes only 6 minutes, the received energy lasts for 30 minutes of driving, quite enough, to reach opposite terminal station.
In addition to seven hybrid, on the line three completely electric buses ply now. Geteborzhtsam promise that the route 55 will work in the usual mode. However commercial operation will begin only in 2017 for now engineers and organizers of the movement develop and improve the most favorable and safe technologies and schemes.
It is expected that each bus of a route in a year “will run“ approximately 60 thousand kilometers. At the same time replacement of accumulators of electric models is planned each 4 years, hybrid - each 6 years.
