System for the storage of electric energy with reduced thickness for a vehicle with electric propulsion and vehicle with hybrid propulsion system with a corresponding storage system
A system (14) for the storage of electric energy with reduced thickness for a vehicle (1) with electric propulsion; the storage system (14) has: a support plane (21); and a plurality of chemical batteries (15), each of which comprises at least one electrochemical cell (24) which rests on the support plane (21) and has a flat parallelepiped shape with two mutually parallel, opposite larger bases; in each chemical battery (15) the electrochemical cell (24) is arranged parallel to the support plane (21) and rests a larger lower base on the support plane (21); and each chemical battery (15) comprises its own compression system (25) which presses directly on a larger upper base of the electrochemical cell (24) opposite to the larger lower base, keeps the electrochemical cell pressed against the support plane (21), and is independent from the compression systems (25) of the other batteries (15).
