How are engineers doing in solving the problem of large-sized all electric transport vehicles traveling long distances without the burden of large batteries? One workaround that has been the topic of much discussion is the use of power lines that are built into the surface of the road. The Volvo Group has issued its state of progress and says it has come a long way in its research but that there’s still work and planning decisions ahead. The goal is to find a cost-efficient way to supply electricity to vehicles in long-distance traffic. Work continues on technical development of the collector, electric motor and control systems, not to mention issues of road construction, road maintenance, electricity supply along the roads and payment models. Translation: You won’t see long-distance buses using this method any time soon.
The Volvo Group nonetheless cannot stop its research momentum for a sustainable transport solution to a problem of a long distance vehicle obtaining its energy supplywhile on the road.
A plug-in bus equipped with battery is all well and good if it can be charged quickly when the buses are at bus stops but that is not the scenario for long-distance hauls where stops are not frequent. To cope with the task, say experts, they would need so many batteries that there would be no room for any passengers. The Volvo Group is engaged in a Swedish research project to find solutions for this, with the support of the Swedish Energy Agency. The project includes the Swedish Transport Administration, Vattenfall, several universities, vehicle manufacturers and suppliers.
