Battery charging and transfer system
First Claim
1. A method of replacing an electric battery in an electrically powered passenger vehicle, comprising the steps of:
- providing a battery transfer station having at least one drive-through bay for receiving an electric passenger vehicle therein, said transfer station having a battery conveyor loop which extends from a first side of the vehicle to a second side of the vehicle when the vehicle is positioned within the bay, a portion of the conveyor loop being elevated or lowered relative to a vehicle level to allow passenger vehicles to pass below or above the conveyor loop, said conveyor loop including an exchange station for conveying a discharged battery out of the vehicle and for conveying a charged battery into the vehicle, said conveyor loop having at least one charging station;
positioning the electric passenger vehicle within the bay, the vehicle having a discharged battery therein, said step of positioning comprising driving the vehicle into an entrance end of the bay;
conveying the discharged battery from a compartment of the vehicle along the conveyor loop to the charging station, the compartment extending through the vehicle from said first side to said second side such that the compartment and said conveyor loop form a closed-loop transfer path when the vehicle is positioned within the bay;
conveying a charged battery along the conveyor loop into the compartment; and
removing the vehicle from the bay in the transfer station, said step of removing comprising driving the vehicle from an exit end of the bay.

Abstract
A battery transfer and charging system for electric vehicles. A displacement station removes spent batteries of electric vehicles by forcing charged batteries into position within the vehicles so as to laterally displace spent batteries. Spent batteries displaced from vehicles are received by a receiving station of the system. The receiving system includes an engagement device for engaging with engagement structures of the batteries, in order to assist the removal of spent batteries. Spent batteries removed from vehicles are tested and charged as they progress through the system in an assembly-line fashion. Following recharge, batteries are conveyed to the displacement station for installation within later vehicles. Batteries which cannot adequately be recharged are automatically removed from the system. In one embodiment of the system, vehicles drive through the system in sequential order, stopping at a specified location for battery installation/removal.

9. A method of establishing a continuous, battery transfer loop and replacing a battery in a vehicle, comprising the steps of:
-
providing a vehicle having a first battery, said first battery positioned in a compartment having a battery installation opening on a first side of the vehicle and a battery exit opening on a second side of the vehicle; engaging the vehicle with a battery transfer station, said battery transfer station including a battery conveyor which extends between said first and second sides of the vehicle when the vehicle is engaged with the battery transfer station, thereby establishing a continuous battery transfer loop between the battery exit opening on the vehicle and the battery installation opening on the vehicle; advancing a second battery along said continuous battery transfer loop, through said battery installation opening on the first side of the vehicle and into said compartment; advancing said first battery from said compartment through said battery exit opening and along said continuous battery transfer loop; and disengaging the vehicle from the battery transfer station, with said second battery in said compartment and said first battery in said battery transfer station; wherein said step of engaging and/or said step of disengaging comprises driving said vehicle above or below a portion of said conveyor. - View Dependent Claims (10, 11)

12. A method for the high speed, continuous, efficient replacement of discharged batteries in passenger vehicles with charged batteries, comprising the steps of:
-
providing a battery transfer station, having a drive through vehicle bay having an entrance on a first end thereof and an exit on a second end thereof to permit the vehicle to enter the bay, stop within the bay, and exit from the bay along a predetermined path without reversing direction; a continuous battery transfer conveyor, having a battery receiving end at a first side of the bay and a battery delivery end at a second side of the bay; at least one battery charging station on the battery transfer conveyor between the battery receiving end and the battery delivery end; and a vertically displaced section of the conveyor, for permitting the conveyor to cross the predetermined path and to place the battery receiving end in communication with the battery delivery end by way of the conveyor without preventing the vehicle from advancing along the predetermined path; advancing a vehicle along the predetermined path and into the bay, said vehicle having a discharged battery in a battery compartment therein, said battery compartment having a battery exit opening on one side of the vehicle, and a battery installation opening on another side of the vehicle; establishing a continuous, closed battery transfer loop from the battery compartment, out the battery exit opening on the vehicle and onto the battery receiving end of the conveyor, along the conveyor to the delivery end, from the conveyor delivery end through the battery installation opening on the vehicle and into the battery compartment; conveying the discharged battery from the battery compartment of the vehicle out through the battery exit opening and onto the battery receiving end of the conveyor; and conveying a charged battery along the conveyor, off of the conveyor delivery end, through the battery installation opening and into the battery compartment in the vehicle. - View Dependent Claims (13, 14, 15, 16)
