Wireless Charging System For Race Cars
HaloIPT, an inductive-charging group, has collaborated with Drayson Racing Technology to formulate its wireless charging technology for high-performance cars. Drayson Racing, which modernizes and races ’green’ motorsport technology, wishes to market HaloIPT’s technology to the motorsport industry as a substitute for the internal combustion engine and pit stops for fuel.

The system is established on Inductive Power Transfer (IPT) wireless charging, which employs powerfully coupled magnetic resonance to carry power from a transmitting pad hidden in the road or race track to a receiving pad on an electric car. The pad in the ground is provided with electrical power at a current typically in the range of 5–125A. The pad is inductive so recompense using series or parallel capacitors is used to decrease the working voltages and currents in the supply circuitry.
Inside the car, pick-up coils are magnetically mated to a primary coil. Power is transmitted by tuning the pick-up coil to the working frequency of the primary coil with a series or parallel capacitor. Agreeing to HaloIPT, the technology automatically adapts to changes in the vertical gap between the car and the surface. It also has the ability to intelligently dissemminate power so that there is a consistent delivery of power at speed.
Lord Drayson, co-founder of Drayson Racing, told #-Link-Snipped-#: "With current battery technology you’re limited to about a 20-minute race in an electric car and that’s why we’re excited about induction-charging technology." He further stated that it could one day be witnessed on roads. "I think that it requires very significant investment into the infrastructure for charging, but it’s a lot safer than the use of cables and it enables you to optimise energy transfer for the use of the car as a tiny storage element in a distributed energy grid. It’s an exciting part of the future."
