It is a quite strange feeling, the first time you run elbuss. The sound of the red buses are a familiar fixture in the cityscape, perhaps so much so that one does not notice it anymore.
Therefore, there is a deafening silence when an electric bus rolling away.
It has been talked about a long time, but in november of this year is actually the first elbussene in traffic in Oslo.
the Following lines get elbusser first:
- Line 74 Vika – Mortensrud T
- Line 60 Vippetangen – Tonsenhagen
- Line 31E and 31
There will only be two elbusser on each line in the testing phase, which runs over two years. The project will cost 43 million, and is supported by Enova.
” The fact that these buses soon in Oslo’s streets, show that the goals are realistic. Electric buses will characterize the cityscape in 2020, says yesterday Raymond Johansen (Ap).
Also the environmental foundation Zero cheering.
– Electric buses are tomorrow’s bussløsninger, which neither gives the emissions of greenhouse gases or local harmful emissions. The buses are in addition virtually noise-free, and provides new opportunities for, among other indoor bus stops, ” says Marius Gjerset, teknologiansvarlig in Zero.
testing the charging on the endestopp and at night
Oslo’s bus lines will be put out for tender periodically. It is the suppliers of busstjenestene even who buy the buses.
They have chosen slightly different concepts:
Unibuss has selected a bus from Solaris with a 74 kWh battery capacity. For comparison, the capacity of the battery on the electric vehicle Opel Ampera-e on the 60 kWh.
It means that the bus will hurtiglade at each endestopp in 6-10 minutes. It is done with a pantograf, which is lowered down on the bus.
On the line 60 has Customers selected a bus from Solaris, with a slightly larger battery of 125 kWh. These buses will be charged at one endestopp, with a pantograf that are lowered down. They should also charge at night.
Nobina has the longest buses in the test, with the largest battery on the 400 kWh. This is leddbusser. They should not charge on endestopp, but in five hours at night.
off the shelf
electric cars are a regular fixture in the cityscape of Oslo, but there is still much that remains to be done. It was emphasized by several during the press conference Wednesday, that this is a test.
Although it has been on the agenda for a while, is it still a development potential. We need optimism and a little patience before we are completely in the goal, ” says Glass-chief Bernt Reitan Jenssen.
Also Customers, who have tested elbusser in Stavanger for several years already, stressed that there are many challenges.
– There are still challenges with the market. This is not off the shelf, ” says managing director Atle Rønning.
the Challenge with winter and topography
It becomes challenging with the Norwegian winter, where the cold will reduce the performance of the battery. There is no one who knows how the logistics will work when the buses go on the power. Another challenge is the topography in Oslo. Oppoverbakker requires more power than the descents.
And what happens if there is a queue on the road, and multiple buses arriving at the charging station at the same time?
– Probably will have to go in with several buses. That is why we have chosen our solution, where you can run longer without recharging, ” says Rønning in Customers.
In the pilot is there to talk about two buses on the line 60, therefore, it is only when elbussene rolls out on a large scale that it can be a problem. All of the bus companies shall, among other things, test whether the elbussene able to run an extra round without charge.
I have absolute faith in this, but it takes probably a bit longer than the politicians would like. At the same time, it is important that they help to create a market for elbusser and that they have ambitions, ” says Rønning.
Should have biodieselvarmer in elbussen
Those who have driven an electric car far know that the air conditioning increase the demand on battery power. The buses will also heat up.
Unibuss, which has the buses with the least battery capacity, to use the biodiesel to warm up the buses.
– It goes with a lot of energy to heat up a bus. We look at solutions where we will use the biodieselbrennere to warm up the bus, ” says the managing director of Unibuss Øystein Svendsen.
This is, in many ways, 1.-generasjonsteknologi, in any case in a systemperspektiv. There are many unanswered questions we must find answers to.
