Filling device for firefighters of a drive battery of an electric or hybrid vehicle
An electric or hybrid vehicle including an arrangement of mechanisms introducing an extinguishing fluid into a battery pack, especially a drive battery, of the vehicle. A first port is placed in a wall of the pack and provides access to an interior of the pack, the first port including a partial or total blocking mechanism being removable or meltable under effect of temperature. A second port is placed in an element of a body of the vehicle facing the first port. Extinguishing fluid may be introduced into the pack through two ports once the blocking mechanism of the first port has been removed or melted.
1. An electric or hybrid vehicle comprising:
a battery pack;
a first port positioned on a wall of the battery pack and that gives access to an inside of the battery pack, the first port including total or partial blocking means, which is removable or meltable under effect of heat; and
a second port positioned on a member of a body of the vehicle facing the first port, such that the second port gives access to the first port;
an extinguishing fluid being introducible into the battery pack through the first and second ports as soon as the blocking means of the first port has been removed or has melted,
wherein the second port includes a grating, the grating isolating an inside of the body from electromagnetic disturbances emitted from the first port, while allowing the extinguishing fluid to pass through.
2. An electric or hybrid vehicle comprising:
a battery pack;
a first port positioned on a wall of the battery pack and that gives access to an inside of the battery pack, the first port including total or partial blocking means, which is removable or meltable under effect of heat; and
a second port positioned on a member of a body of the vehicle facing the first port, such that the second port gives access to the first port;
an extinguishing fluid being introducible into the battery pack through the first and second ports as soon as the blocking means of the first port has been removed or has melted,
wherein the battery pack is placed under a trunk of the electric or hybrid vehicle, and the first port is positioned on top of the battery pack and the second port is positioned on a floor of the trunk, facing the first port.
3. The electric or hybrid vehicle as claimed in claim 1 , wherein the blocking means of the first port includes a blocking piece composed at least partially of a material which is meltable under effect of heat.
4. The electric or hybrid vehicle as claimed in claim 3 , wherein the blocking piece includes a valve.
5. The electric or hybrid vehicle as claimed in claim 3 , wherein the blocking piece includes a coupling sleeve.
6. The electric or hybrid vehicle as claimed in claim 2 , wherein the second port includes a grating, the grating isolating an inside of the body from electromagnetic disturbances emitted from the first port, while allowing the extinguishing fluid to pass through.
7. The electric or hybrid vehicle as claimed in claim 1 , wherein the grating is incorporated in a sheet metal stamping die for the body.
8. The electric or hybrid vehicle as claimed in claim 1 , wherein the second port includes second blocking means which are removable or meltable under effect of heat.
9. The electric or hybrid vehicle as claimed in claim 8 , wherein the second blocking means of the second port includes a fusible soundproofing sheet.
10. The electric or hybrid vehicle as claimed in claim 1 , wherein the battery pack is placed under a trunk of the electric or hybrid vehicle, and the first port is positioned on top of the battery pack and the second port is positioned on a floor of the trunk, facing the first port.
11. The electric or hybrid vehicle as claimed in claim 2 , wherein the blocking means of the first port includes an area of reduced thickness of the wall of the battery pack, the area being breakable by mechanical action.
12. The electric or hybrid vehicle as claimed in claim 2 , wherein the blocking means of the first port includes a blocking piece composed at least partially of a material which is meltable under effect of heat.
13. The electric or hybrid vehicle as claimed in claim 12 , wherein the blocking piece includes a valve.
14. The electric or hybrid vehicle as claimed in claim 12 , wherein the blocking piece includes a coupling sleeve.
15. The electric or hybrid vehicle as claimed in claim 11 , wherein the second port includes second blocking means which are removable or meltable under effect of heat.
16. The electric or hybrid vehicle as claimed in claim 15 , wherein the second blocking means of the second port includes a fusible soundproofing sheet.
17. An electric or hybrid vehicle comprising:
a battery pack;
a first port positioned on a wall of the battery pack and that gives access to an inside of the battery pack, the first port including total or partial blocking means, which is removable or meltable under effect of heat; and
a second port positioned on a member of a body of the vehicle facing the first port, such that the second port gives access to the first port;
an extinguishing fluid being introducible into the battery pack through the first and second ports as soon as the blocking means of the first port has been removed or has melted,
wherein the second port includes second blocking means which are removable or meltable under effect of heat.
18. The electric or hybrid vehicle as claimed in claim 17 , wherein the second blocking means of the second port includes a fusible soundproofing sheet.
19. The electric or hybrid vehicle as claimed in claim 17 , wherein the blocking means of the first port includes a blocking piece composed at least partially of a material which is meltable under effect of heat.
20. The electric or hybrid vehicle as claimed in claim 19 , wherein the blocking piece includes a valve or a coupling sleeve.
