Named “Dancer”, this light-weight, low-floor bus will be powered solely by electricity and, having run several routes, will charge the battery for another voyage without the driver’s assistance.
Klaipėdians designed the monocoque type body which is connected from the individual modules and has the structure reminiscent of an airplane fuselage. Before assembling the bus, chassis, batteries as well as control and other systems are integrated into the modules; electric motors are mounted on each wheel.
“We were searching for ideas in aviation and sailing sports. To reduce the vehicle weight even by 10 per cent in the car industry is a great challenge, because it is not that the construction is changed but that individual parts are refined. We started with a clean sheet of paper,” said Alvydas Naujėkas, the General Manager of the company “Vėjo projektai”.
More economical than competitors
“We have analysed Lithuanian and European city bus routes and have concluded that 50 km is the optimum distance covered by the charged battery,” said A. Naujėkas. He claimed that 6 minutes is enough to charge the battery in order to travel this distance.
Currently 12-meter-long city buses, with electricity-powered prototypes being produced and tested in several countries, cost from 430,000 to 700,000 euro. The price of this product developed in Klaipeda will be closer to the lower limit of the range. The developers claim that “Dancer” will use 450 watt-hour of electricity per kilometre which is two times less than what the current competitors need.
Most parts for “Dancer” will be supplied by Lithuanian companies which produce them for global car and bus companies.
