Definitions
- the invention relates to an electrically operated vehicle, containing
- a vehicle can be moved on land, water or air.
- a vehicle may be a passenger car, truck, RV, sailboat, ship, airplane, motorcycle, and the like.
- energy stored chemically in the fuel is first converted into thermal energy and then into mechanical work.
- energy stored in a battery is converted into mechanical work via an electric drive.
- energy chemically stored in a fuel such as hydrogen, is converted directly into electrical energy and then into mechanical work.
- hybrid drives In addition to these forms of drive, mixed forms, also known as hybrid drives, are known. These use a conventional combustion engine and an additional electrically powered drive with a battery as energy storage. As long as the battery supplies energy, it will the vehicle is powered exclusively by electrical energy. The internal combustion engine is then used as the main drive. Depending on the design, the battery can be charged through recuperation or, in the case of plug-in hybrids, from external energy sources.
- Hybrid drives use two main drives and two associated energy storage devices - battery and fuel tank. These have a complex structure and are heavy, thereby increasing manufacturing costs, maintenance costs and energy requirements.
- the disadvantage of exclusively electrically powered vehicles is the limited range, the long charging time and the short lifespan of the batteries. These adverse effects occur more frequently at low temperatures, especially in cold regions, at night and in winter. At low temperatures, the efficiency of the battery decreases. This requires the battery to be heated. The heater is powered by energy from the vehicle battery. This also applies to the passenger compartment. This also needs to be heated electrically to warm it up. This affects the range of the vehicle.
- DE102009035471A1 discloses a vehicle with a temperature control device for temperature control of a vehicle battery in a vehicle, in which a heat engine or fuel cell is provided as the main drive and the vehicle battery is provided for operating auxiliary units.
- DE102011079640A1 discloses a cooling system for a fuel cell system with heat extraction.
- the system includes a stationary energy supply system with a fuel cell system with a fuel cell cooling circuit for cooling the fuel cell system and a battery cooling circuit for cooling a battery.
- the thermal energy between the fuel cell cooling circuit and the accumulator cooling circuit is exchangeable.
- DE102014009772A1 discloses an electric vehicle with a fuel cell system.
- the fuel cell system is intended for recharging the electrical energy storage device.
- DE102017006158A1 discloses a method for operating an electric vehicle with a range extension by emptying an energy source before energy is absorbed again.
- DE102011076737A1 discloses a device for providing electrical energy, in which the electrical energy storage is thermally coupled to the fuel cell arrangement by means of a heat transfer arrangement.
- the well-known fuel cell arrangement is permanently installed in the vehicle. The associated additional costs and additional weight are therefore incurred even when they are not needed, for example if the vehicle is to be used in warmer climates or only in the summer, or if the vehicle is regularly parked in a garage where a additional heating of the battery is not necessary.
- the object is achieved in that the tank and the fuel cell form modules with which the vehicle is retrofitted.
- Vehicles that are to be used at low temperatures can be retrofitted with the modules.
- the otherwise unchanged vehicle can be retrofitted permanently or temporarily, for example for the cold season. Retrofitting with modules enables the production of identical vehicles for both applications - with and without fuel cells - and thus in higher quantities. A higher number of pieces has an advantageous effect on the manufacturing costs.
- vehicle components especially electrical components such as motors, inverters, etc. can also be heated.
- the modules can be used as heating and... Power generator combination can be used for mobile applications in camping, for emergency supplies, in emergency shelters, at events and the like.
- the tank forms its own module and is detachably inserted into the vehicle. Then the tank does not have to be refueled specifically. Rather, the tank can be replaced as a whole, similar to cartridges in a soda bottle.
- a deposit system can be set up or existing pressure vessel systems can be used.
- the fuel cell primarily serves as a heat source. High efficiency is achieved when the electrical power generated during operation is used. This can be done directly by connecting electrical consumers. However, it is advantageously provided that the fuel cell is connected to the vehicle battery and electrical energy can be fed into the vehicle battery during operation. Then only one connection is required and the electrical consumers are supplied in the usual way via the on-board network.
- the fuel tank is a hydrogen tank and the fuel cell can be operated with hydrogen. It goes without saying that other fuel cell technologies are also possible.
- a control unit can be provided for controlling the fuel cell, which operates the fuel cell at least partially in accordance with a temperature value.
- the fuel cell can therefore always be operated when the temperature of the energy storage unit of the vehicle's main drive falls below a threshold value. It can also be operated if, for example, the passenger compartment needs to be heated.
- a method of operating a fuel cell may include the steps:
- the temperature value may represent the temperature in the passenger compartment of a vehicle or a vehicle battery. However, other temperature values, for example in the cargo area, can also be regulated to a setpoint.
- the electrical energy is advantageously stored in a vehicle battery, which is intended to drive a vehicle. This can extend the range. Alternatively or additionally, the electrical energy can be fed into the on-board electrical system of a vehicle with one or more electrical consumers. This is particularly useful if a consumer requires permanent electrical energy, for example if an electrical consumer is a cooling unit. Energy losses and signs of aging in the battery due to temporary storage are minimized.
- the object according to the invention is also achieved by an auxiliary unit for retrofitting a vehicle with an additional energy source
- Such an auxiliary unit can be installed in any series vehicles. Installation is carried out as required, i.e. the costs and effort only arise if the vehicle is to be driven at low temperatures and a long range is desired.
- the auxiliary unit can also be used for other purposes. It is particularly advantageous if the tank is detachably connected to the module. The tank can then either be refilled, for example when installed, or exchanged for a full tank.
- the tank, the fuel cell and the control unit are arranged in a module that can be mounted together and has interfaces via which the module can be connected to the respective functional units of the vehicle.
- the module can then also be installed and removed by vehicle mechatronics engineers and other specialists who are not familiar with fuel technology. It is sufficient if you know which interfaces the module is connected to in the vehicle. Refinements of the invention are the subject of the subclaims. An exemplary embodiment is explained in more detail below with reference to the accompanying drawings.

- Fig. 20 is a schematic representation of the circuits for the stationary application of the arrangement from Figure 10.
- Figure 1 shows a vehicle generally designated 10.
- the vehicle 10 is a passenger vehicle. It goes without saying that the invention can also be used for any other vehicle, i.e. trucks, mobile homes, sailboats, ships, airplanes, motorcycles and the like.
- the vehicle has a cavity at the back or front, such as a trunk 12 or 18, respectively.
- a fuel cell module 14 can be installed in the trunk 12 or 18.
- the fuel cell module 14 is supplied with hydrogen from a tank 16 via a supply line 20.
- FIG. 2 shows the fuel cell module 14 and the tank 16 in detail.
- the tank 16 comprises two pressure vessels 22 with a volume of, for example, 6 l each and, for example, 350 bar or 700 bar, which are filled with liquid hydrogen.
- other gases or liquids can of course also be used in more or fewer pressure vessels 22.
- the pressure vessels 22 are bottle-shaped and secured to a common base plate 24 in a crash-safe manner.
- Tension straps 26 are provided for this. It goes without saying that other crash-safe fastenings are also possible instead of tension straps.
- the base plate 24 can be firmly screwed into the vehicle or fixed in some other way before the pressure vessels 22 are attached. This makes the installation of the base plate 24 easier.
- the tension straps 26 can also be operated by laypeople, so that the pressure vessels 22 can be easily released and replaced, maintained and/or filled if necessary.
- the supply line 20 to the fuel cell module 14 is provided with a manually operated shut-off 28 on the module side. It goes without saying that instead of a manually operated barrier, automatically closing barriers are also possible.
- T-pieces 30 and 34 or a corner piece 32 are installed in the supply line 20 upstream of the barrier 28. About the T-piece 30 is a first pressure vessel 22 is connected. It goes without saying that additional pressure vessels can also be connected via additional T-pieces. Another pressure vessel is connected to the corner piece 32. If only one pressure vessel 22 is provided, no T-piece 30 is required. It goes without saying that instead of a corner piece 32, a linear connection is also possible.
- a filling connection 36 with a valve that opens in the direction of the supply line is connected to the T-piece 34.
- the pressure containers 22 can be filled and refilled via the filling connection 36 when the shut-off 28 is closed. Instead of filling the pressure containers 22 via the filling connection 36, empty pressure containers 22 can also be replaced by full pressure containers.
- a quick connection 38 is opened and the tension straps 26 are released.
- the quick connector 38 can, for example, be designed similarly to commercially available quick connectors for hoses from garden technology, in which the opening in the pressure container 22 is closed by a valve as soon as the quick connector 38 is released. It goes without saying that any other connection can also be used.
- replaceable pressure containers 22 enables the use of a deposit system so that not every gas station has to provide the required fuel at a gas pump.
- the tank 16 is firmly integrated into the fuel cell module 14 and housed together with it. Then only one nozzle is accessible from the outside for filling. The fuel cell module 14 is then slightly larger, but easier to install.
- Figure 2 shows the fuel cell module 14 with a simple housing 40 made of thin sheet metal.
- the housing 40 serves to protect against environmental influences, dust and unauthorized access.
- Figure 3 shows the arrangement from Figure 2 without housing 40.
- a support structure 42 can be seen on which the housing 40 is held.
- the support structure 42 includes a front 50, a back 52, side walls 54 and 56, a bottom 58 and a top 60.
- the side walls 54 and 56 and the bottom 58 of the support structure 42 are made of a solid material, for example 4 mm thick steel, in order to avoid damage to the components inside as much as possible, even in the event of an accident.
- the interior of the essentially cuboid-shaped support structure 42 is easily accessible via an opening 44 in the top 60 and several openings 46 in the side walls 54 and 56.
- the components of the fuel cell module 14 described below are attached to this support structure 42.
- the openings 44, 46 enable access to the interior and, on the other hand, also reduce the weight of the fuel cell module 14. In addition, less material is required for the support structure 42. This reduces costs.
- Figure 4 shows the fuel cell module 14 without side walls 54 and 56 and without top 60 from a first perspective in which the front 50 can be seen completely.
- Figure 5 shows the same fuel cell module 14 from a second perspective, in which the back 52 can be seen completely.
- the front 50 has an opening 62 provided with a grid. Air is sucked in from outside through opening 62. This is illustrated in Figure 14 by an arrow 74. The air flows through a filter and a funnel 64 into a compressor or blower 66. This is illustrated in FIGS. 14 and 15 by an arrow 74. In the compressor or blower 66, the air is compressed from the ambient pressure in the range of 1 bar to a higher pressure of, for example, 1.3 bar and transported into the fuel cell.
- the output of the compressor or blower 66 is connected to a humidifier 68 via a connecting line 70.
- the humidifier 68 the water content of the air is increased.
- the air is supplied from the humidifier 68 to the fuel cell 76 via a line 80.
- the fuel cell is attached to the rear wall 52 of the support structure 42 and can be clearly seen in FIG.
- An increase in the air pressure and thus the amount of oxygen at the cathode 98 of the fuel cell 76 has a positive effect on the performance of the fuel cell 76, but at the same time requires more drive power on the compressor 66.
- the compressor 66 is the largest consumer of all components in the fuel cell module 14. The operating strategy is therefore crucial for a good overall efficiency of the fuel cell module 14.
- the cathode circuit is illustrated separately again in FIG.
- a high-pressure valve 82 and subsequently a low-pressure valve 84 are arranged in the line 20.
- the high-pressure valve 82 the pressure of the fuel from the tank 16 is reduced from, for example, 700 bar or 350 bar to a lower pressure of, for example, 10 bar.
- the subsequent, controllable low-pressure valve 84 regulates the pressure of the fuel to the required operating pressure of the fuel cell 76, for example between 1 and 2.5 bar.
- the low pressure valve 84 thus regulates the pressure to the operating pressure of the anode circuit.
- An optional heat exchanger 102 is used to adapt the gas temperature to the fuel cell temperature.
- the fuel is fed via a supply line 86 to the anode of the fuel cell 76.
- the hydrogen path (anode subsystem) described in this way is illustrated separately again in FIG. It provides the required amount of hydrogen in the correct concentration, pressure and temperature to the fuel cell 76 for the electrochemical reaction.
- the fuel reacts with the oxygen contained in the air.
- the way fuel cells work is well known and therefore does not need to be explained in more detail here. In principle, any fuel cell is suitable.
- the fuel is molecular hydrogen and the fuel cell is a low-temperature polymer electrolyte fuel cell, also referred to as NT-PEM-BZ.
- the reaction produces heat and water.
- a voltage is generated on the electrodes.
- the water generated in the fuel cell 76 is sent via a line 88 to the humidifier 68. There it is used to humidify the air entering the arrangement. Behind the humidifier, the gas is released to the outside as exhaust gas via a check valve 92. The check valve can also be designed as a siphon. This is illustrated in Figure 14 by an arrow 94. Heat is generated during operation of the fuel cell 76. The heat is dissipated via a cooling circuit generally designated 96. The cooling circuit 96 is illustrated separately again in FIG. Depending on the quality of the hydrogen, the present fuel cell 76 achieves electrical efficiencies of up to 40%. This means that up to 60% of the energy supplied is generated as heat during operation. The thermal output is therefore in a similar range to the useful electrical output. The operating temperature is comparatively low and is in the range of 60 to 85°C. For this reason, the exhaust gas enthalpy is low and the exhaust gas enthalpy flow reaches a proportion of 5-15%.
- the electrical power of the fuel cell system results from the power of the fuel cell stack minus the power of the components.
- the electrical efficiency results from the effective power described above, the mass flow of the hydrogen and its calorific value:
- connection is that the greatest effective efficiency is achieved at low current densities. At high current densities, the electrical efficiency decreases due to the increasing power requirements of the components and the decreasing fuel cell efficiency.
- the thermal power will also be determined from the power of the fuel cell stack, the fuel energy supplied and the exhaust gas enthalpy flow. The following relationship results for the thermal efficiency
- the overall efficiency of the fuel cell module 14 increases as the heat is utilized. In winter operation, an overall efficiency of over 90% can be achieved.
- the thermal output can be used in the mobile application as heating heat for the vehicle interior and as a heat source for the thermal management system of the vehicle battery at operating temperature.
- the heat from the fuel cell 76 is absorbed and dissipated via the cooling circuit 96.
- the design of the thermal management required for this depends not only on the connection to the fuel cell 76 but also on the auxiliary units used and their integration into the vehicle.
- the main task of thermal management is to monitor the temperature of the components, regulate the optimal temperature range and ensure a quick start-up after standstill.
- Figure 14 and Figure 17 show the required components and their interconnection.
- the coolant is passed through a filter 112 to a coolant pump 110. This pumps the coolant through the fuel cell 76, where the reaction heat is absorbed. Part of the coolant is directed via a throttle valve 114 to electronic components 116 in the vehicle that need to be cooled and where heat is also absorbed.
- the warm coolant streams are brought together again at a T-piece 118.
- the warm coolant can be conveyed from there to the vehicle battery 120 and/or into the passenger compartment. This is where the heat is given off. If no heating is to occur, the coolant can be routed via a bypass 122.
- a bypass valve 124 is provided for this purpose. The bypass valve 124 overrides the thermal coupling in order to stop introducing excess heat into the vehicle, for example because the fuel cell takes too long to shut down.
- the 3-way valve 124 is used to ideally distribute the heat flow to a cooler or a heat exchanger for heating the vehicle battery 120 or the vehicle interior.
- the cooling medium must be electrically insulating because it is in direct contact with the conductive bipolar plates. This can be achieved, for example, by using deionized coolants.
- An integrated control device 126 at the bottom of the support structure 42 controls, regulates and monitors the operation. It includes the different operating modes, such as the starting process, the three operating points and the shutdown process.
- the controller 126 communicates with the vehicle control unit. In particular, signals relating to temperatures and battery status of the vehicle are read out at the control unit diagnostics interface.
- the control device 126 is specifically supplied with signals via signal lines, which Represent temperature of the battery 120, the passenger compartment and the fuel cell 76.
- the control unit 126 is also supplied with signals which represent the state of charge of the battery 120.
- the fuel cell module 14 can replace the heater that is otherwise installed as standard. However, the measuring points remain the same. If the temperature falls below a threshold value, the fuel cell 76 is switched on.
- a heat exchanger is provided in the housing for heat transfer.
- the input and output of the heat exchanger each form interfaces for water or glycol lines.
- the filling opening for example, is suitable for connection.
- the lines can be broken open and fitted with a T-piece.
- Water pipes are connected to the heating circuit, for example of the passenger compartment and/or the battery and/or possibly other components.
- the regulation by the controller is based on the vehicle outlet temperature at the heat exchanger. If only inlet temperature signals are available, the heat loss value for the vehicle may be determined or estimated to take path losses into account.
- the fuel cell module 14 provides energy that is cost-effective, makes optimal use of the hydrogen and has low complexity. Instead of combining a large fuel cell with a small battery as in today's common fuel cell vehicles, the present invention takes the opposite approach.
- a small fuel cell that delivers up to 11 kilowatts of electrical power, for example, is installed in an electric vehicle with normal storage capacity. This approach allows not only the costs and the package but also the application effort to be significantly reduced.
- it can be operated stationary in, for example, three operating points. Since the load points are charging points for the vehicle battery, this also helps with integration and integration into the vehicle. Example operating points are listed below:
- medium load point with an electrical power of 3.6 kW and a thermal power of 6.2 kW. This is useful, for example, for operating operationally relevant consumers in the vehicle, such as lights and fans.
- high load point with an electrical power of 11.0 kW and a thermal power of 20.5 kW. Such a load point is particularly useful for additional consumers, for example if a cooling or air conditioning system is to be operated or a mobile office is being operated.
- switch-on conditions include the thermal switch-on conditions when the vehicle is switched off, no charging current is flowing, the outside temperature is below 15°C and the battery charge level allows charging, i.e. that the battery is not already fully charged.
- the electrical switch-on conditions include that the vehicle is driving and, according to the navigation device, the range is not sufficient to reach the destination with the current charge level of the battery.
- the charge level of the battery must allow charging. In principle, operation makes sense if the temperature of the battery is below the optimal operating temperature of, for example, 15°C.
- Retrofitting vehicles with an electric main drive is advantageously only necessary if the temperatures at the locations where the vehicle is moved actually fall below the threshold of, for example, 15 ° C.
- fuel cells also work in cold temperatures and prevent the battery from freezing.
- the fuel cell module can have its own small battery for its own operation and the start-up phase.
- the fuel cell module 14 can also be used in the stationary area, for example when camping or as an emergency power supply for agricultural machinery, construction machinery, for the fire department and in disaster control as a replacement for emergency generators that are powered by climate-damaging fossil fuels.

- the tank 16 can be attached to the panel on the back of the base 204 with the base plate 24.
- Figure 11 shows the base 204 without casing.
- the base 204 is provided with a floor 212 slightly above ground level.
- a conversion unit 222 is attached to the floor 212, which converts the voltage provided by the fuel cell module 14 into a voltage required by the consumer, for example an alternating voltage of 230 V or 400 V.
- the power is transferred to projecting connections 214 on the top of the base 204, which interact with the connections 200 on the bottom of the module 14.
- a refill port 216 for cooling water on the base 204 which can be closed with a screw cap, enables the cooling circuit 224 and expansion tank 218 to be filled and refilled with coolant.
- the coolant pump 226 can be seen in Figure 13.
- a fan 220 is also arranged on the floor 212.
- the fan 220 serves to dissipate heat to the outside into the area below the floor 212.
- a capacitor 228 is arranged above the fan 220. This can be clearly seen in Figures 11 and 13.
- the fuel cell module 14 is placed on the base 204 between two angles 230 and 234 (FIG. 11) and can be held and fastened there with straps 232 on fastening angles 236. This is illustrated in Figure 10.
- a heat exchanger 238 for the fuel and the condenser 228 with fan 220 are integrated into the cooling circuit. These are located in base 204.
- Fig. 19 is a further variant of Figure 14 with two separate heat exchangers for, for example, a battery and the cabin 320.
- Fig. 20 shows circuits for the stationary application of the arrangement from Figure 10.
- a filter 227 can optionally be arranged in front of the pump.
