The future belongs to electric cars
Professor Matti Lehtonen believes that electrification will involve even heavy traffic. According to him, it is pointless to fear that the proliferation of electric cars would turn current emissions from cars to emissions caused by the production of electricity.
‘It’s amazing how little electricity a car ultimately needs to run compared to, for instance, the heating of houses. A week of heating the summer cottage with electricity is the equivalent of a 2000km drive with an electric car. When we all drive electric cars, the demand for electricity increases only by 10% compared to today’, he says.
Smart charging of electric cars will be piloted in the parking hall of the Aalto Works block in Otaniemi. Electricity price fluctuations and currently available forms of electricity production will be taken into account in the charging of electric cars. It is worthwhile to utilise excess solar energy in the charging of electric cars. If electricity is required for other purposes, it can, in extreme situations, be transferred from the electric car’s battery to the electrical network.
Otaniemi has dozens of buildings, and a few of them will be equipped and harnessed into a single virtual power plant compiled of small production and consumption units. Since such a power plant will consist of different ways of producing and consuming electricity, it will be flexible: wind and solar power can be used whenever available. When there is no wind or sunshine, other methods of electricity production can be used or the consumption reduced. A virtual power plant will enable the use of renewable production methods without problems in the availability or quality of electricity. Both the energy and the flexibility can be sold in Fingrid’s reserve market additionally paying back the investment.
In the new Väre building, in turn, heat is stored deep in the ground. Heat can be stored in the summer and used in the winter.
There are other options for charging an electric car than plugs and sockets. Wireless charging requires a strong magnetic field, which may be dangerous to humans. For the magnetic field not to be harmful to humans, the vehicle must be in the correct position with millimetre-accuracy. The following description could be true of public transport in the future:
A bus stops at a bus stop. Automation runs it to exactly the correct position with millimetre accuracy, so that the magnetic fields do not spread and affect people. While the passengers get on and off the bus, the strong magnetic field charges the batteries of the electric bus so that the journey can continue.
Are you interested in Smart Otaniemi? We are looking for new pilots again. Come and join us! In addition to a good idea, you will need get 2 to 3 companies involved. DL for the applications is 1 November.
