This enables a vehicle fire to be easily contained therein preventing further damage to adjacent vehicle or buildings. The trailer further includes a longitudinal door allowing viewing and nitrogen extinguishers to be used on the fire. A storage area for storing a fire blanket is configured above the trailer wheels and can be deployed over the wheel to prevent damage during the fire. ## Claims ### Claim 1 An electric vehicle fire suppression trailer comprising: a frame for supporting an enclosure having no floor; a plurality of wheels sharing an articulating axle for enabling the enclosure to be move between a raised and a lowered position where the frame contacts the ground in a lowered position; and wherein a rear door of the trailer is configured between an open position when moving the enclosure over a vehicle fire and a closed position for fully containing the vehicle fire for preventing the vehicle fire from spreading to other vehicles or buildings. ### Claim 2 (depends on 1) An electric vehicle fire suppression trailer as in claim 1, further comprising a longitudinal door configurated on a side of the frame for allowing a nitrogen fire extinguisher to access a fire within the trailer. ### Claim 3 (depends on 1) An electric vehicle fire suppression trailer as in claim 1, further comprising: a tongue configured on a front of the trailer enabling it to be towed. ### Claim 4 (depends on 1) An electric vehicle fire suppression trailer as in claim 1, further comprising: a storage box configured above each wheel for deploying a fire blanket over the wheel. ### Claim 5 An electric vehicle fire suppression trailer comprising: a frame for supporting an enclosure having no floor; a plurality of wheels each having an articulating axle for enabling the enclosure to be move between a raised and a lowered position where the frame contacts the ground in a lowered position; a compartment configured above the plurality of wheels having a fire blanket stored therein for covering at least one of the plurality of wheels during a fire; and wherein a rear door of the trailer is configured between an open position for moving the enclosure over a vehicle fire and a closed position for fully containing the vehicle fire preventing the vehicle fire from spreading to other vehicles or buildings. ### Claim 6 (depends on 5) An electric vehicle fire suppression trailer as in claim 5, further comprising a longitudinal door configured on a side of the frame for allowing a nitrogen fire extinguisher to access a fire within the trailer. ### Claim 7 (depends on 5) An electric vehicle fire suppression trailer as in claim 5, further comprising: a tongue configured on a front of the trailer enabling it to be towed. ### Claim 8 (depends on 5) An electric vehicle fire suppression trailer as in claim 5, further comprising: a front storage box at a front of the trailer for housing a fire suppressant gas. ### Claim 9 An electric vehicle fire suppression trailer comprising: a frame for supporting an enclosure having no floor; a plurality of wheels each having an articulating axle for enabling the enclosure to be move between a raised and a lowered position where the frame contacts the ground in a lowered position; a compartment configured above the plurality of wheels having a fire blanket stored therein for covering at least one of the plurality of wheels during a fire; a plurality of jacks configured about the perimeter of the frame for lifting the frame from the ground without use of the articulating axle; and wherein a rear door of the trailer is configured between an open position for moving the enclosure over a vehicle fire and a closed position for fully containing the vehicle fire preventing the vehicle fire from spreading to other vehicles or buildings. ### Claim 10 (depends on 9) An electric vehicle fire suppression trailer as in claim 9, further comprising: a tongue configured on a front of the trailer enabling it to be towed. ### Claim 11 (depends on 9) An electric vehicle fire suppression trailer as in claim 9, further comprising: a front storage box at a front of the trailer for housing a fire suppressant gas.
