Definitions
- the invention relates to a method for operating a fuel cell vehicle according to the preamble of claim 1 and a fuel cell vehicle according to the preamble of claim 10.
- Fuel cell vehicles can have unique noise characteristics due to their different operating modes.
- CN 112224041 A describes a noise reduction structure of a heat dissipation assembly of a fuel cell vehicle.
- the fuel cell vehicle is provided with a heat dissipation water tank, a fan assembly, and a storage battery.
- a DC-amplified DC/DC converter is arranged on a power circuit from the storage battery to the fan assembly, and the DC/DC converter is connected to a vehicle control unit via a signal circuit. Further, a noise suppression method of the noise reduction structure is described.
- the noise level of the heat dissipation assembly of the fuel cell system can be effectively reduced in the entire operating state range, and compared with the prior art, the noise can be reduced by 17 dBA-22 dBA.
- the invention is based on the object of specifying a novel method for operating a fuel cell vehicle and a novel fuel cell vehicle.
- the object is achieved according to the invention by a method for operating a fuel cell vehicle with the features of claim 1 and by a fuel cell vehicle with the features of claim 10.
- a fuel cell vehicle has a fuel cell system, a traction battery and at least one electric drive motor that can be supplied with electrical energy from the fuel cell system and/or the traction battery.
- a method according to the invention for operating the fuel cell vehicle it is provided that in a first operating mode the fuel cell system and the fuel cell vehicle are operated particularly quietly by one or more of the measures possible depending on the current vehicle state.
- the quiet first operating mode for fuel cell vehicles contributes to a quieter urban environment and facilitates compliance with legal framework conditions such as the "Technical Instructions for Protection against Noise".
- the operator of the fuel cell commercial vehicle is thus able to deliver goods at night when traffic is low.
- the measures include:
- the noise-intensive units comprise at least one cooling fan and/or at least one compressor.
- components of the fuel cell vehicle and/or the fuel cell system are preconditioned for an upcoming journey in an urban area.
- the preconditioning comprises at least one of the following measures:
- the fuel cell vehicle when taking into account the planned arrival time and/or delivery of goods in the second operating mode, it is detected whether the fuel cell vehicle is driving or will be driving through an urban area within a time in which a reduced emission limit applies, whereupon it is ensured by preconditioning and controlling the components of the fuel cell vehicle and/or the fuel cell system that the fuel cell vehicle does not exceed this limit.
- activation and/or deactivation of the first and/or second operating mode occurs manually and/or automatically by means of geofencing and/or by means of predictive route planning and/or predictive control of a drive train of the fuel cell vehicle.
- the predictive route planning and/or the predictive powertrain control predicts that the fuel cell vehicle will pass through an urban area.
- the first operating mode is activated when it is detected that the fuel cell vehicle is in an urban area.
- a fuel cell vehicle comprising a fuel cell system, a traction battery and at least one electric drive motor which can be supplied with electrical energy from the fuel cell system and/or the traction battery, wherein the fuel cell vehicle is configured to carry out the method according to one of the preceding claims.
- the fuel cell vehicle is a commercial vehicle, a passenger car or a bus.
- Fig. 1 is a schematic view of a fuel cell vehicle.
- the sole figure 1 is a schematic view of a fuel cell vehicle 1, in particular a fuel cell commercial vehicle.
- the fuel cell vehicle 1 has a fuel cell system 2, an acoustic vehicle alert system 3 (AVAS - Acoustic Vehicle Alert System) for generating acoustic warning signals when maneuvering and driving at low speeds, a traction battery 4 and at least one electric drive motor 5, which can be supplied with electrical energy from the fuel cell system 2 and/or the traction battery 4.
- the fuel cell vehicle 1 also has a cooling system 6, which is configured to cool the fuel cell system 2 and possibly other components and has at least one cooling fan 7.
- the fuel cell vehicle 1 has at least two operating modes for particularly low-noise operation.
- the fuel cell system 2 and the fuel cell vehicle 1 are operated particularly quietly by one or more of the measures possible depending on the current vehicle state.
- components of the fuel cell vehicle 1 and/or the fuel cell system 2 can be preconditioned for an upcoming journey in an urban area via predictive route planning. This can be done, for example, by at least one of the following measures:
- the fuel cell vehicle 1 When including planned arrival times and/or planned delivery of goods in the second operating mode, it can be detected whether the fuel cell vehicle 1 is driving through an urban area during a time (for example 22:00 - 06:00) in which a reduced emission limit applies, whereupon it can be ensured that the fuel cell vehicle 1 does not exceed this limit by preconditioning and controlling the components of the fuel cell vehicle 1 and/or the fuel cell system 2 (for example maintaining a certain charge level (SOG) of the traction battery 4 and/or reducing the noise emitted by the vehicle warning system 3 to a legally permissible minimum).
- SOG charge level
- the activation and/or deactivation of the operating modes can be done manually by the driver and/or automatically by means of geofencing and/or predictive route planning and/or predictive control of the drive train.
- Activation/deactivation by means of geofencing also includes the detection of entering or leaving an urban area by means of sensors.
- predictive route planning and/or predictive control of the drive train predict that the fuel cell vehicle 1 will pass through an urban area.
- the quiet first operating mode can be activated immediately.
