The WiT-3300 is a wireless “Park-and-Charge” self-charging system for electric vehicles. The system provides an efficient wireless energy transfer solution that completely avoids the need for the driver to plug in their battery electric vehicle or PHEV.
Energy transfer over a distance and through paving materials
The WiT-3300 is designed to transfer energy over distances ranging from 10-20cm, and custom configurations can be provided for vehicles having higher or lower ground clearance. Wireless energy transfer can occur through any non-metallic material, which means that the source device can be installed beneath a garage floor or paved parking space.
WiTricity’s patented energy transfer system does not require the source and capture resonator pairs to be perfectly aligned in order to achieve efficient energy transfer. In addition, our strongly coupled magnetic resonance energy transfer provides products which are 4x smaller, 2x lighter, and more efficient than solutions based on traditional magnetic induction.
The WiT-3300 provides a complete set of wireless energy source and capture modules that can be integrated into an EV or PHEV for a truly wireless park-and-charge system.
The WiT-3300 enables users to evaluate, demonstrate, and develop applications for WiTricity's patented (US 7,825,543 & US 7,741,734) and patent pending technology for wireless energy transfer. The kit demonstrates WiTricity's unmatched ability to transfer energy over distance, through paving materials, and without requiring precise parking alignment.
