Electrical/Electronic Architecture

Delphi is developing a Wireless Charging System for Consumer Devices that will automatically transfer power to mobile electronic devices, providing a convenient and safe wireless energy transfer system. The system will be a product differentiator for advanced technology vehicles and is being developed in cooperation with a wireless energy transfer technology provider. A magnetic field from a source resonator in the vehicle provides power to the devices, enabling in-vehicle, high efficiency device charging that is safe for humans without the hassle of cords or connections.

This hands-free charging technology is based on highly resonant magnetic coupling which transfers electric power over short distances without physical contact. The wireless charging system will include:

• Capture resonator and interface electronics
• Stationary source or sources resonator pad
• Optional repeater coils

Unlike inductive systems, which require precise positioning of devices, this highly resonant magnetic coupling technology allows freedom of positioning for the devices while charging. Since no pad is required, the devices can be charged while being held by a user, in a cup holder, etc. The system will fully charge a device at a rate comparable to most residential plug-in chargers.

Tomorrow's solution: Automatic and convenient charging of mobile electronic devices with the Delphi Wireless Charging System for Consumer Devices — without any charge cords, plugs and adaptors.

Benefits

• Convenience and simplicity
• Minimal action needed
• Will enable easy, automatic charging within the vehicle environment, without plugging in
• System will activate the moment a device is within the range of the charging pad
• Hands free — no moving or mechanical parts
• Will eliminate distracting charge cords, plugs and adaptors
• Large range vs. conductive chargers
• Will transmit power over greater distances by charging via magnetic resonance technology
• Will provide power needed to charge typical devices, from milliwatts to tens of watts
• Safe and reliable
• Engineered to provide a safe, robust, and quick charge
• Non-radiative power transfer uses a magnetic near field
• Minimal heating and energy transfer losses to extraneous or off-resonant objects
• Magnetic, non-ionizing system will meet industry safety guidelines and regulations
• ICNIRP (International Commission of Non-Ionizing Radiation Protection)
• IEEE (Institute of Electrical and Electronics Engineers)
• FCC (Federal Communications Commission)
• Will help eliminate driver distraction
• Can assist with meeting local transportation laws regarding device use while driving
• Passive charging will ensure device operation when needed
• Will enable vehicle interior design flexibility
• Superior transmit range for design freedom
• Non-contact system will not require precise device positioning
