Solarmobil Austria, an initiative for the realization of innovative mobility concepts, has set a milestone in the direction of the creation of emission-free public transport systems with the project “Solarbus”. The Solarbus has a 1.2 kWp solar roof and an electric heat pump. A further special design feature is the optimal integration of the replacement battery (lithium-ion battery) into the low-floor vehicle floor. The range of a battery is 80 to 100km. However, 250km \/ day (regular bus) or 180km \/ day (local bus) are required for everyday use. A continuous operation is made possible by a battery change by the driver within approx. Two minutes. The empty battery can be fully charged at a charging station during the driving cycle and is immediately available again.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

An electric heat pump is used for the heating and cooling of the bus interior. In addition, the engine heat is also used. The Solardach of the bus offers some energy-economic advantages. The power of the battery is efficiently supplemented by the solar power inputs. During high-voltage operation, additional power can be fed into the system; the batteries are charged when the power requirement is low. Despite the batteries and the Solardach, the lightweight design of the Solarboard with a weight of 4,650 kg (regular bus) does not weigh more than a comparable variant with a diesel engine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In model communities, two bus formats have been tested since 2011, a 35-seat regular bus and a community bus with 9 seats. The latter is used in a demand-controlled traffic system. The electric motors have a nominal capacity of 50 kW (municipal bus) and 70 kW (regular bus). The drive is made by a newly developed, automatic 2-speed gearbox with an efficiency increase of 25%. In operation the solar bogies reach a maximum speed of 80 km\/h.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
