NOVELTY - A vehicle includes pack of chemical batteries (18) that directly lies on the support panel (24) without any intermediate element. For each chemical battery, the support panel has a corresponding through hole which makes up a corresponding evacuation opening (28). Each chemical battery is provided with an outlet duct (27), which connects the safety valve of the chemical battery only to the corresponding evacuation opening obtained through the support panel and is independent and separate from the outlet ducts of the other chemical batteries.    USE - A vehicle.    ADVANTAGE - The vehicle is easy and cost-effective to be implemented.    DETAILED DESCRIPTION - A vehicle comprises a floor (15) which makes up a bottom wall of the compartment and comprises a bottom panel beneath which there is the external environment; a motor propulsion system provided with electric machine(s); and a system for the storage of electric energy which lies on the bottom panel and comprises a pack of chemical batteries (18), which are connected to each other in series and in parallel and comprise respective electrochemical cells. Each chemical battery is provided with a safety valve. The pack of chemical batteries directly lies on the support panel (24) without any intermediate element. For each chemical battery, the support panel has a corresponding through hole which makes up a corresponding evacuation opening (28) and is separate and independent of the through holes of the other chemical batteries. Each chemical battery is provided with an outlet duct (27), which connects the safety valve of the chemical battery only to the corresponding evacuation opening obtained through the support panel and is independent and separate from the outlet ducts of the other chemical batteries. An INDEPENDENT CLAIM is included for a storage system.    DESCRIPTION OF DRAWING(S) - The drawing is a sectional diagram of the system for storing electric energy.
