SUMMARY OF THE INVENTION

An electric drive for a vehicle absolutely requires a battery. Batteries represent a concentration of electrical energy that can ignite, resulting in a vehicle fire.

An object is therefore to provide an electric vehicle that enables a battery fire to be extinguished effectively.

A first aspect of the invention is an extinguishing agent for extinguishing a fire in a vehicle, in particular a harvesting machine or combine harvester or passenger car 08/02/2022

S0086/TM or truck or electric vehicle, or house, where the extinguishing agent is nitrogen or CO2.

In particular, the extinguishing agent can be stored in the vicinity of batteries or containers of batteries in order to extinguish them in the event of a fire.

A second aspect of the invention is a vehicle, in particular an electric vehicle, comprising a battery for supplying the vehicle with electrical energy, the vehicle having an extinguishing device for extinguishing a fire in the battery or the engine or the vehicle, the extinguishing device containing an extinguishing agent according to one of Claims 1 to 3.

Exemplary embodiments are described in the dependent claims.

According to an exemplary embodiment of the invention, an extinguishing agent is provided, with the extinguishing agent being arranged in a container, with the container being replaceable.

The interchangeability of the container means that maintenance can be carried out easily and empty containers can be exchanged for full containers.

According to an exemplary embodiment of the invention, an extinguishing agent is provided, the extinguishing agent being provided for extinguishing an engine, in particular an internal combustion engine or an electric motor, the engine producing exhaust gases, in particular CO2, which are conducted into a container in order to extinguish the engine or associated vehicle in the event of a fire.

The CO2 can be generated by the engine to extinguish a fire in the engine, battery or associated vehicle. In addition, the CO2 is then advantageously accumulated by the container while the engine is still running 08/02/2022

S0086/TM runs so that in the event of a fire, if the engine is no longer running, the extinguishing agent CO2 is available to extinguish.

According to a further exemplary embodiment of the present invention, a vehicle, in particular an electric vehicle, is made available, the extinguishing device being arranged around the battery or the motor and/or in the direct vicinity of the battery or the motor.

According to a further exemplary embodiment of the present invention, a vehicle, in particular an electric vehicle, is made available, a sensor system being arranged on the battery or the motor in such a way that a fire in the battery or the motor can be detected.

In a further embodiment according to the invention, a vehicle, in particular an electric vehicle, is made available, with the extinguishing device comprising a shower, with the shower being able to sprinkle large areas of the battery or the engine with an extinguishing agent.

With a shower, the extinguishing agent can be applied very efficiently to a burning car battery, thereby smothering the fire.

According to a further exemplary embodiment of the present invention, a vehicle, in particular an electric vehicle, is made available, the electric vehicle comprising a container with CO2 or nitrogen for extinguishing a fire in the battery or the engine or the vehicle.

In a further embodiment according to the invention, a vehicle, in particular an electric vehicle, is made available, the battery being arranged in a pan in order to enable the battery or the motor to be flooded with extinguishing agent. 08/02/2022

S0086/TM

By arranging the battery in a tray or a hermetically sealed container, a battery fire can be extinguished by filling the tray or container.

In a further embodiment according to the invention, a vehicle, in particular an electric vehicle, is made available, the battery or the motor being arranged in a container in order to flood the battery with extinguishing agent.

A fire in a combustion engine can be extinguished by the device according to the invention.

An idea of the invention can be seen as providing an electric vehicle that includes an extinguishing device for extinguishing a battery fire, the extinguishing device being able to extinguish the battery fire with nitrogen or CO2.

The individual features can, of course, also be combined with one another, which in some cases can also result in beneficial effects that go beyond the sum of the individual effects.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Fig. 1 shows an electric vehicle 1 with a battery 2, in which a extinguishing device 3 is arranged above or in its immediate vicinity.

2 shows an electric vehicle 1 with a battery 2 and a plurality of extinguishing devices 3 which are arranged around the battery 2. FIG. In addition, a warning system 4 is arranged around the battery 2, which can detect a fire in the battery 2.

3 shows a hybrid drive with a combustion engine 5, a steam engine 6 and an electric drive 15. The electric drive 15 is supplied with electrical energy by a battery 3. FIG. Sensors 4 are arranged on the battery 3 in order to be able to detect a fire in the battery 3 . If the battery 3 catches fire, the container 10 can be used to extinguish the fire.

Fig. 4 shows the hybrid drive with the electric motor 15 and the battery 3, wherein the battery 3 is provided with a shower 11 for extinguishing agents. The shower 11 is on 08/02/2022

S0086/TM

Part of the extinguishing device 3, which also includes a tank 10 for CO2 or nitrogen. The container can be designed as a container.

5 shows a hybrid drive with a battery 3 for an electric motor 15 of a vehicle, the battery 3 being surrounded by showers 11 which can spray extinguishing agents onto the battery. The showers 11 are supplied by pipes 3 which are fed from a tank 10.

FIG. 6 shows a battery 2 for an electric motor of a vehicle, which is arranged inside a trough 13 . The trough 13 can be flooded by an extinguishing device 3, as a result of which a fire in the battery 2 can be safely extinguished.
