Bus laboratory: forerunner in energy efficiency, kilometres without emissions

TAMK has commissioned Tampere Electric Wheel Center to launch a project to produce a bus laboratory, in collaboration with the research, technology and educational partners of the field. In practice, the laboratory will be a bus, which has operated in fixed-route transportation, and will be converted to use electricity. The conversion includes removing the combustion engine, and installing electric motor, batteries and new driving control systems.

Technical innovations

The technical structure will be implemented modularly. This structure enables the testing of various electric motor uses, as well as comparing batteries and hybrid systems. The bus will be used to study mains charging, and the functionality of driving control systems and software. The bus will become a platform where the parties involved with electric transportation can test their systems. The bus will also be used to evaluate the functionality of driving an electric vehicle in traffic.

The driving control system enables versatile energy measurements while driving. Through this, and other computerised systems, various energy efficient driving methods can be studied. The information systems can also be used to examine and implement fully new cabin services.

Aim to create emission free kilometres

The converted bus will operate in normal city traffic. Due to its electricity, the bus will not produce particulate nor exhaust gas emissions. Energy created while driving can be recycled through an electric system. The braking energy can be used to recharge the battery, which in turn reduces the total consumption of energy. The technology will be displayed prominently, so the citizens may also get to know the new technology through the bus.

New cabin innovations

The interior tests a modification structure, where the number of seats can flexible be adjusted to suit the current requirements. The bus may be transformed into a more tram-like vehicle by reducing the number of seats and adding standing room. This makes the bus more suitable for rush-hour traffic or event transportations. Some of the space may be used for entirely other purposes, such as presentation, meeting or laboratory spaces, which makes the bus even more versatile for research projects.


In the future, the bus laboratory will support and enable the electric car business to develop itself and to organise training in Tampere. The bus laboratory will be the first bus converted by the Electric Wheel Centre. The know-how acquired in the project may lead to serial conversion production in the Electric Wheel Centre. A concurrent operations model for the future is launching the production of new cars in collaboration with a suitable chassis and body producer.

Emissions free traffic and giving up oil-based energy sources are the future. Tampere and Tampere University of Applied Sciences want to show the way and be the forerunners of the field, both nationally and internationally.
