System for the storage of electric energy with reduced thickness for a vehicle with electric propulsion
First Claim
1. A storage system for the storage of electric energy, the storage system comprising:
- a support plane; and
a plurality of chemical batteries, each chemical battery including at least one electrochemical cell that rests on the support plane and comprises a flat parallelepiped shape with two mutually parallel, opposite larger bases;
wherein each electrochemical cell in each chemical battery is arranged parallel to the support plane and rests on a lower larger base on the support plane;
wherein each chemical battery includes a compression system configured to contact directly on a larger upper base of the electrochemical cell opposite to the lower larger base and configured to keep the electrochemical cell pressed against the support plane, the compression system independent from other compression systems of the other chemical batteries thereby configured to autonomously generate a thrust independent from thrusts generated by the other compression systems of the other chemical batteries;
wherein the compression system of each chemical battery includesa pair of support elements rigidly fixed to the support plane, rising from the support plane, and arranged on opposite sides of the electrochemical cell, andat least one strap which is wound around the pair of support elements and is pulled taut between the two support elements;
wherein each support element includes, for each strap, a bar around which the strap is wound in a loop; and
wherein each support element comprises a parallelepiped shape with a triangular cross-section having cavities, each cavity defining a corresponding bar.

Abstract
An embodiment of a system for the storage of electric energy with reduced thickness for a vehicle with electric propulsion; the storage system has: a support plane; and a plurality of chemical batteries, each of which includes at least one electrochemical cell which rests on the support plane and has a flat parallelepiped shape with two mutually parallel, opposite larger bases; in each chemical battery the electrochemical cell is arranged parallel to the support plane and rests a larger lower base on the support plane; and each chemical battery includes its own compression system which presses directly on a larger upper base of the electrochemical cell opposite to the larger lower base, keeps the electrochemical cell pressed against the support plane, and is independent from the compression systems of the other batteries.
