System and method for rapid battery exchange in electric vehicles
First Claim
1. A battery exchange system comprising:
- an electric vehicle comprising;
a first battery within a battery house located on an underside of the vehicle comprising a first and second contact rail extending a length of the first battery, the first and second contact rails of the first battery fitted to engage first and second front contact rods and first and second rear contact rods extending from the vehicle, the contact rods each comprising first and second rollers at distal ends, the first rollers each connected to the first battery and the second rollers each connected to the battery house for the contact rods to reach from the underside of the vehicle to a top side of the first battery as the first battery is lowered from the battery house;
a self-contained propelling mechanism within said vehicle for moving the vehicle forward as the first battery is exchanged with a second battery; and
an exchange plate comprising;
the second battery comprising a first and second contact rail extending a length of the second battery, the first and second contact rails of the second battery fitted to engage the first and second front and rear contact rods, the second battery located on the exchange plate and the second battery to be exchanged with the first battery;
a mount on the exchange plate keeping the second battery in place over the exchange plate as the vehicle moves forward and the first battery touches the second battery to provide continual charge to the electric vehicle through a connection between the first and second contact rails of the second battery and the first and second front contact rods and the first and second contact rails of the first battery and the first and second rear contact rods; and
at least one post connected to the exchange plate, the post fitted to disengage one or more latches of the battery house as the vehicle moves over the post such that the first battery becomes located on the exchange plate and positioned horizontally next to the second battery and reengage the one or more latches of the battery house once the second battery is in place within the battery house.

Abstract
A system and method for the rapid exchange of batteries in an electric vehicle. The electric vehicle contains a removable battery housed in the vehicle'"'"'s undercarriage. The electric vehicle moves through the exchange system either by propelling itself or by being propelled by the system. As the vehicle is propelled forward, the removable battery within the vehicle is unlocked from the vehicle and replaced with a charged battery. The charged battery forces the removable battery out of the rear of the vehicle as the vehicle moves forward through the exchange. The vehicle remains powered throughout the exchange process. Once the charged battery is aligned in position under the vehicle and connected to the vehicle through corresponding contacts, the charged battery is located into place in the vehicle'"'"'s undercarriage and the vehicle is ready for additional driving.

11. A vehicle battery exchange system comprising:
-
a first battery contained in a battery house on the underside of said vehicle and held in place by a latch, said first battery having a contact rail for connecting with a contact rod in said battery house, said contact rod comprising first and second rollers at distal ends, said first roller connected to said first battery and said second roller connected to said battery house for said contact rod to reach from said underside of said vehicle to a top side of said first battery as said first battery is lowered from said battery house; a second battery removably fixed to an exchange plate, said second battery having a contact rail for connecting with a contact rod in said battery house; a self-contained propelling mechanism within said vehicle for moving said vehicle such that said first battery comes in contact with and is then ejected from said battery house by said second battery; said exchange plate further comprising; a mount to hold said second battery in place on said exchange plate and to align said second battery with said first battery to facilitate said battery exchange, and a post to disengage said latch to allow battery exchange and to reengage said latch following battery exchange. - View Dependent Claims (12, 13)
