Electrical energy storage device for a motor vehicle
First Claim
1. A motor vehicle for transporting loads in excess of 100 pounds, the vehicle comprising:
- a frame;
a plurality of wheels rotatably mounted on the frame;
an electric motor for driving at least one of the wheels; and
an electrical energy storage device electrically connected to the motor for energizing the motor, the device including;
(a) a casing;
(b) a plurality of electrically connected coiled windings disposed within the casing, each winding including a cathode plate including a strip having a pair of elongated side edges, an anode plate including a strip having a pair of elongated side edges, and a separator located between the cathode and anode plates, the cathode plate and the anode plate being wound in an offset relationship so that one elongated side edge of the cathode plate extends beyond one elongated side edge of the anode plate at a first side of the winding, and the other elongated side edge of the anode plate extends beyond the other elongated side edge of the cathode plate at a second side of the winding opposite the first side;
(c) an electrolyte material located within each winding; and
(d) and a plurality of current collectors disposed within the casing, at least one of the current collectors being pressed against one of the first and second sides of each winding to electrically contact the corresponding winding side at a plurality of locations thereon.

Abstract
An electric energy storage device, comprises a casing and a coiled winding disposed within the casing. The winding includes a cathode plate including a strip having a pair of elongated side edges, an anode plate including a strip having a pair of elongated side edges, and a separator located between the cathode and anode plates. The cathode and anode plates are wound in an offset relationship so that one elongated side edge of the cathode plate extends beyond one elongated side edge of the anode plate at a first side of the winding, and the other elongated side edge of the anode plate extends beyond the other elongated side edge of the cathode plate at a second side of the winding opposite the first side. An electrolyte material is located within the winding. Two current collectors are secured to the casing, one current collector being pressed against the first side of the winding to contact the cathode plate at a plurality of locations thereon, and the other current collector being pressed against the second side of the winding to contact the anode plate at a plurality of locations thereon. A pressure vessel may be provided to hold at least one of the casings having at least one of the windings therein. An electric vehicle includes a plurality of the energy storage devices.
