## Abstract

An electric public transport land vehicle, in particular of the bus, coach or tyred tram type, including at least one rechargeable electrical energy storage module arranged in a peripheral panel of the vehicle, and having, for at least one electrical energy storage module, a protective cover equipped with at least one evacuation opening allowing smoke and/or flame and/or gas to escape in a direction away from the vehicle in the event of fire in the module.

## Claims

### Claim 1

An electric public transport land vehicle, in particular of the bus or coach or tyred tram type, comprising: at least one rechargeable electrical energy storage module arranged in a peripheral panel of said vehicle; for at least one electrical energy storage module, a protective cover equipped with at least one evacuation opening for allowing smoke and/or flame and/or gas to escape, in a direction away from the vehicle, in the event of fire in said module.

### Claim 2 (depends on 1)

The vehicle according to claim 1, characterized in that at least one said protective cover of a module has a shape folded on at least two of its sides, in particular a “U” shape, so as to cover a first face of said module, turned towards the outside of said vehicle, and at least a portion of two faces of said module adjacent to said first face.

### Claim 3 (depends on 1)

The vehicle according to claim 1, characterized in that for at least one said protective cover, at least one evacuation opening is equipped with a fixed louvre.

### Claim 4 (depends on 1)
