Pioneer trailer

Tver, OOO "PK Transport system" invented an original method for extended range electric buses

Last may 16-17, in ECC "Sokolniki" exhibition "electrotrans-2018", by the way, dedicated to the forthcoming world football Championship FIFA 2018, the center place in all senses has taken the theme of buses. This is not surprising, because, until the end of the year, the capital's bus fleet needs to grow at least a hundred buses that will bring Moscow into among the most elektrobosna capitals of the world and of course the mass operator of such equipment among the cities in Russia.

The battery trailer on the road train pioneer and quite aesthetic

In turn, among the buses shone newest model of "pioneer" produced by "PC Transport system" from Tver. The machine is fully low-floor with aluminum body designed for 29 seats and total capacity of 85 people. But, it is not that, and the fact that the manufacturer is enough witty decided the basic question of increasing the mileage of electric bus while maintaining acceptable operating parameters.

Ease of replacement of the trailer with batteries allows you to bring the actual production of electric bus bus parameters

This was done due to the innovative system of dynamic charge from the mobile battery systems housed in the trailer, components of electric bus with a small trailer. Thus the battery is saved and on the bus (on the roof). Their capacity is 50 kWh, and the trailer carried three batteries with a total capacity of 150 kWh.

The joint connectors between the bus and trailer

Thanks to two electric motors at 110 kW each pioneer can reach a maximum speed of 70 km/h. Such a "hook" technology allows the buses to avoid delays not only at terminal stations, but even on any "fast" chargers: precepta trailer with the discharged battery to another fully charged battery takes less than five minutes. Accordingly, at terminal stations is not required and any special equipment. Particularly promising in this design gives the expansion of possible areas of operation of buses on interurban services, including long distance.

Another advantage of this trailer is the rational use of the internal space of the electric bus of the tractor

However, the "tram" design ideology of the manufacturer still affected – as under the cab shield too much space (the wall of the cabin video as tram) shifted forward over the front axle, and together with sliding plug doors it really reminds the Belarusian trolleybuses "Vytautas". The heating and air conditioning, although implemented on the principle of heat pump, but also are powered by battery.

On the bus "pioneer" implemented in full low-floor layout options thanks to the trailer battery

P. S. Bus trailer as a booster to increase the reserve of what is called well-forgotten old. So scarce on fuel during the Second world war almost all European countries (including neutral) was used in the trailers with the gas plants as wood chocks and corner.



In the 1980s in Europe experimented with trolleybuses with an Autonomous course that provides just the trailers of similar purpose.
