Project about inductive chargers and how these can influence the way we use transport.


We are working for a company which has developed the use of the high power inductive energy transfer to create wireless charging for the PRIMOVE vehicles.  One of the components is a buried underground station used as an emitting device and the receiving equipment is installed beneath the vehicle. As soon the vehicle covers the charging segment the contactless charging process starts automatically.


Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery.

The two induction coils in proximity combine to form an electrical transformer.


Essentially the device and the charging station form a two-part- transformer, with the charging having one part of the transformer and the device having the other.  When the device slides on to the station the complete transformer is created and the energy can flow.
This system has is highly efficient and fast.  Those vehicles can be charged rapidly and seamlessly either in motion (dynamic charging) or at rest (static charging) without the need for extra fleet vehicles or batteries.

Volvo is another company which also has developed its own inductive charging for one of its model lineup.

“Volvo is focusing on the C30 electric design and hopes to make it as comfortable, sporty and safe as the standard car. The electric C30 will have a range of up to 150 kilometers per charge and have a top speed of 130 km/h. Volvo’s ambitious ‘Drive towards Zero’ program has the goal of a complete range of electric and plug-in hybrid cars.”
