article imageSweden to test wireless charging of buses on city roads in 2016

By James Walker     Dec 20, 2014 in Science
The Swedish city of Södertälje is to begin testing of a new wirelessly charged electric-hybrid city bus system on its roads in 2016 as part of efforts to reduce fuel consumption and pollution in the country.
Devised by Swedish heavy vehicle manufacturer Scania, famed for their trucks, coaches and buses, the trial begins in June 2016 and will utilise a brand-new cutting-edge bus stop. When a specially-equipped Scania bus approaches the stop, a special wireless charging system cuts in to transfer power into the bus.
Only six or seven minutes — the time that many buses wait at some stops and depots — is required to add enough charge for a complete journey to be made. Scania, whose main manufacturing plant is based in the city, sees huge potential in using zero-emission commercial vehicles that can be charged through normal operation. With a current fleet of 2000 buses, the company envisages fuel cost reduction of up to 90 percent in a year at around 50 million liters less than is currently used.
A hybrid bus prototype equipped with the new fast wireless charging service — but otherwise the same as a conventional Scania bus — will enter regular service when the test begins. A dedicated bus-stop will be installed in the city to transfer power through the road surface to the vehicle's wireless receiver.
The driver and passengers shouldn't have to wait at the stop any longer than on a diesel-powered bus, but the vehicle will have fully recharged before it leaves. If proven successful, this technology could very well become the norm throughout Swedish cities within a few years and indeed throughout Europe as a viable, attractive method of making buses cleaner and quieter is finally presented by a leading manufacturer.
