New Solutions for Electric Vehicles
As gas prices continue to jump up at the pump, the future of electric vehicles is looking bright. The Volvo Group is working on improving electric vehicles and looking for more solutions for vehicles to operate on renewable energy. The company has proposed a future where trucks and buses and continuously supplied with electric power but without batteries. Rather, power lines are built into the surface of the road.
Mats Alaküla, Volvo Group’s expert on electric vehicles and professor at Lund University notes that a challenge is supplying a vehicle with electrical power when needed. “In city traffic, there are currently various solutions and we are researching many others. We have field tests in progress where our plug-in buses are equipped with a battery that can be charged quickly when the buses are at bus stops.”
However, Alaküla notes that using batteries to power trucks and buses traveling long distance will not work. These vehicles stop infrequently and would need so many batteries there would be no room for loads or passengers. This is why the company is searching for a solution to constantly provide power to a truck or bus from an external source through its participation in a large Swedish research project with the support of the Swedish Energy Agency.
The method currently being developed and tested by the Volvo Group, together with Alstom, entails two power lines built into the surface of the road along the entire length of the road. A current collector in contact with the power lines will be located on the truck. With this method, electric vehicles could be continuously supplied with power without carrying large batteries explains Alaküla. The power line will be built in sections and one section is only live as the truck passes.”
