German city to test viability of inductive charging system on two real bus lines

Feb 27, 2013 by Bob Yirka report

(Phys.org)—Canadian company Bombardier, Inc's rail division based in Berlin Germany, has announced the approval of a test run of an all electric bus recharging system in the city of Mannheim. The power systems are based on the company's PRIMOVE Technology, whereby vehicles are charged inductively while pausing to load and unload passengers. The primary purpose of the test-run is to determine whether such a system is viable in a real-world environment.

Plans call for two Swiss built busses (Carrosserie HESS AG) to be retrofitted with the PRIMOVE Technology—streets will be dug up at stops to embed the other half of the technology beneath the road bed. Once installed, an initial test run of the system will commence to ensure all of the parts are working correctly. Once that is completed, the two busses will run their normal bus routes (with passengers) for 12 months, during which time researchers from the Karlsruhe Institute of Technology will be analyzing data from the system to monitor, tweak and build a knowledge base of information to be used in building future test sites to optimize the system overall.

An inductive charging system is wireless; current is passed through the air—in this case from beneath the roadbed to components installed in the undercarriage of a bus. For such a to work as part of a bus line, the right size batteries must be used. Ideally, small batters can be employed as they will be given frequent charges—this allows for increased efficiency due to a lighter battery load. The batteries must be just large enough to ensure a bus can complete its route each day without ever having to stop for just recharging purposes. In addition to providing a city with (at the point of use), electric busses also reduce . As part of testing the system, researchers will also be speaking directly with passengers to get their ideas on how well the busses work within the system.

The has stated its intent to pursue electric technology for busses in the country and has backed up that pledge by offering funds to various projects. For this test, the country's Federal Ministry of Transport, Building and Urban Development will be footing the bill to the tune of €3.3 million (US$4.35 million).

I'm happy to see a German city, spending money it doesn't have, rather than an American city.

Wolkenkuckucksheim, indeed.

Wolkenkuckucksheim, indeed.

Please. I know you like to use foreign sounding words. But it just makes you look like an uneducated fool to use such words not correctly.

A "Wolkenkuckucksheim" is a utopia. Something fanatstical (and positive) and - and this is important - not real.
It was origially a word to describe a fictional bird city (lit.: a home for cuckoos built in the clouds)

A worldwide hippy commune would be a Wolkenkuckucksheim - because it will never exist, and has no chance to exist.

An inductive rail system in Mannheim is not a Wolkenkuckucksheim because it will be built.

(BTW: That word is so antiquated that no german speaker alive would ever use it. It sounds just like I would sound if I would call fraudulent things "humbug".)

This is not new. Induction charging electric buses has been around for some years.

I like the way current is passed through the air. That must be difficult.
