Greentech Lead U.S: Car Charging Group, a
provider of convenient electric vehicle (EV) charging services, has filed a
utility patent application (#13600058) with the United States Patent and
Trademark Office for an inductive EV charging station in the form of a parking
bumper.
Transmitting the energy through a bumper, which is common
in most parking lots, provides seamless and effortless charging, as it will
only require the EV driver to park the car’s wheels near the charging
apparatus.
Currently, most EV charging stations require a cord in
order to plug in and charge the EV. These cords are typically 18 feet long
and can be bulky for some EV drivers. To eliminate the plug in cord,
inductive charging methods, which utilize an electromagnetic field to transfer
energy, have been introduced. To charge the EV, rather than plugging in
the cord, the EV must be placed in close proximity to the energy source
providing the electricity.
Today, inductive charging equipment for EVs are primarily
in the form of charging plates, on top of which EVs park. The placement of
the EV over the charging plates can be misaligned; therefore, reducing the
efficiency of the charge. Additionally, for multi-level parking garages,
the installation of the charging plates can cause structural issues, which
causes the installation to be very expensive, if not impossible.
CarCharging technology is designed to address these
issues and provide property owners and EV drivers with a simpler, less
expensive solution. This original invention intends to deliver the charge
through equipment generally utilized in parking lots and/or parking garages, which
is familiar to most drivers and conforms to standard parking practice.
CarCharging’s focus will be on the design and placement
of the inductive EV charging station rather than the wireless energy transfer
technology involved. CarCharging plans to adapt the design of the
inductive EV station to integrate with the magnetic coupling technology offered
by providers such as Qualcomm, Delphi, Siemens, Evatran, and others that may
enter the market.
CarCharging also intends to incorporate the charging
standard currently being developed by the Society of Automotive Engineers
International (“SAE”), which will establish the minimum performance
and safety criteria for wireless charging, into the design of the inductive EV
charging station.
