… our Motivation

The limited range of electric vehicles today is inhibiting the success and

acceptance of electric propulsion as a replacement for the internal

combustion engine.

Recharging vehicles with a plug and cable is only possible while stationary

and often takes a relatively long time. If vehicles could be charged faster

and more often, the problem of limited range would be solved.

This is where inductive power transfer systems can help; they don’t require

cables or a direct contact to transfer energy and can also be used while the

vehicle is on the move (known as dynamic charging).

Dynamic charging allows electric vehicles to become as flexible as their

internal combustion engine counterparts. Inductive power transfer is a key

technology in the journey to making electric mobility a success.

free

1 2 3

4 5 6

Cable-free power transmission

independent of user (driver)

ensuring automated, on-demand

power transmissions

Avoid unwieldy cabling and

charging plugs

Enables reduced on-board battery

capacity making vehicles lighter,

giving more internal space and

comfort, increasing safety and

lowering the price of the vehicle

Longer battery life-time & higher

energy efficiency, avoidance of fast

battery charging and dedicated

stops for charging

Invisible, components are fully

enclosed

Wear and maintenance free,

insensitive to vandalism
