Inductive charging of a moving electric vehicle's battery
First Claim
1. An apparatus for inductively charging a battery of an electric vehicle equipped with an inductive charging coil while the electric vehicle is moving, comprising:
- means for establishing a two-way wireless communications link between said apparatus and said electric vehicle for communicating in accordance with a service protocol one or more of the following, a charging request, a customer service number, battery specific data, autopilot commands, and electronic billing information;
means for producing a magnetic field along different portions of an extended linear distance and for individually controlling a time/intensity characteristic of said magnetic field of each different portion; and
means for sensing progress of said electric vehicle along said extended linear distance.

Abstract
A battery of an electric vehicle is inductively charged while the electrical vehicle is moving, using a magnetic field along different portions of an extended linear distance and an inductive coil mounted on an electric vehicle, by having the electric vehicle, as it traverses the different portions of the extended linear distance, move within the influence of the magnetic field. An apparatus senses progress of the electric vehicle along the extended linear distance. The apparatus produces the magnetic field by a power switch bank connected to an array of inductive coils.

7. A method of inductively charging a battery of an electric vehicle while the electric vehicle is moving, using a charging system including means for producing a magnetic field along different portions of an extended linear distance and an inductive coil mounted on said electric vehicle, the method comprising the steps of:
-
establishing a two-way wireless communications link between the charging system and the electric vehicle; exchanging information between the charging system and the electric vehicle across said two-way wireless communications link in accordance with a service protocol regarding one or more of the following, a charging request, a customer service number, battery specific data, autopilot commands, and electronic billing information; and having said electric vehicle, as it traverses different portions of said extended linear distances, move within the influence of said magnetic field. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
