Inductive bus-stop charging Södertälje

It is very simple: we are building a single inductive bus stop charging in Södertälje not only to show it can reduce 60% of energy consumption and lower CO2 emissions compared to a traditional bus, but to study and develop vehicle- and road-side technology. It will also give us opportunities to study the need for new business models and its’ attractiveness for users and operators. 

The induction technology, electricity transferred without cables or wires, is well known: you find it in electric toothbrushes or in your stove, but it needs to develop further to serve the transport sector with energy. This is the first Swedish test in the field with inductive technology.

 

Scania and the municipality of Södertälje are cooperating in this project that involves a prototype bus from Scania that will run as a regular public bus line. The purpose is to study and evaluate this technology during a longer period of time, 2015 – 2017.

Inductive technology does have a great potential: Infrastructure that supports electric vehicles could save approximately 50 million liters of fuel in a fleet of 2000 busses and it reduces costs with 90% when leaving fossil fuels for electricity. But todays fleet of electric vehicles rely on batteries and for busses these batteries need to be of great size (that means weight) to last for a whole day. If the bus is not filled with people it then carries more weight in battery than people which in the end lead us to more vehicles and more traffic. Batteries in itself is also a scarce resource since they contain limited materials such as rare metals and used batteries are difficult to recycle. Induction needs lighter batteries and therefore less material. These batteries also last longer.
