The number of teeth of the second gear 108 is set to be smaller than the number of teeth of the first gear 107, and the output shaft 109 rotates at a faster rotational speed than the crankshaft 101. For example, the number of teeth of the second gear 108 relative to the first gear 107 may be ½.

  The ACG 43 is a known three-phase AC generator. The rotation shaft of the ACG 43 is connected to the output shaft 109 of the transmission 42. As a result, the ACG 43 is driven at a higher rotational speed than the crankshaft 101. The ACG 43 is connected to the generator-side electrical connector 51 and the generator-side power converter 46 via the power line 60.

  The generator side power converter 46 converts the three-phase alternating current supplied from the ACG 43 into a 100V single-phase alternating current of 50 to 60 Hz. The generator-side power converter 46 is connected to the external output connector 54 via the power line 60. The external output connector 54 is configured in the same manner as a plug receptacle (socket) of a commercial power supply 100V, and a plug of a commercially available electrical device can be connected.

  The generator-side ECU 45 is connected to the internal combustion engine 41, the generator-side power converter 46, the generator-side electrical connector 51, and the gaseous fuel switching valve 94 via a signal line 61. When the engine generator 8 is mounted on the vehicle body 2, the generator-side ECU 45 is connected to the vehicle body-side ECU 16 via the generator-side electrical connector 51 and the vehicle body-side electrical connector 31, and the engine generator 8 is connected to the vehicle body. 2 is detected. Further, the selection state of the gaseous fuel switching valve 94 is detected based on a signal from the gaseous fuel switching valve 94.

  The generator-side ECU 45 changes the combustion condition of the internal combustion engine 41 based on a signal from the gaseous fuel switching valve 94. For example, when the gaseous fuel switching valve 94 is in the third state, the generator-side ECU 45 drives the liquid fuel injection device 81 to inject gasoline and controls the ignition timing of the spark plug, etc. Set conditions suitable for combustion. Further, when the gaseous fuel switching valve 94 is in the first state or the second state, the generator-side ECU 45 stops the liquid fuel injection device 81 and drives the gaseous fuel mixing device 82 to ignite the spark plug. Control the timing, etc., and set conditions suitable for the selected gas. Further, when the generator-side ECU 45 determines that the engine generator 8 is in the vehicle body mounted state based on the signal from the vehicle body side ECU 16, the generator-side ECU 45 is more than in the non-mounted state in which the engine generator 8 is separated from the vehicle body 2. Also increases the engine speed.

  In the electric vehicle 1 configured as described above, the engine generator 8 in the mounted state functions as a part of the vehicle. The engine generator 8 can be detached from the vehicle body 2 and used as a general-purpose generator independent of the vehicle body 2.

  In the electric vehicle 1 equipped with the engine generator 8, the vehicle body side ECU 16 controls the PDU 17 and the engine generator 8 to supply electric power to the electric motor 5 from the secondary battery 7 or the engine generator 8 via the PDU 17. The vehicle body side ECU 16 controls the engine generator 8 based on, for example, a request output based on the accelerator operation of the passenger and the potential of the secondary battery 7 (remaining battery level). In the engine generator 8, the generator-side ECU 45 controlled by the vehicle body-side ECU 16 controls the internal combustion engine 41.

  FIG. 4 shows the ACG output and the charge / discharge amount of the secondary battery with respect to the required output when (A) the potential of the secondary battery is high and (B) the potential of the secondary battery is low. As shown in FIG. 4A, when the potential of the secondary battery 7 is high (that is, when the remaining capacity of the secondary battery 7 is sufficient) and the required output is small below a predetermined value, 2 The electric power of the secondary battery 7 is supplied to the electric motor 5. On the other hand, in a state where the required output exceeds a predetermined value, the engine generator 8 is driven and the electric power from the ACG 43 is supplied to the electric motor 5. At this time, surplus power from the ACG 43 is supplied to the secondary battery 7 and the secondary battery 7 is charged.

  On the other hand, as shown in FIG. 4B, when the potential of the secondary battery 7 is low, that is, when the remaining capacity of the secondary battery 7 is small, the engine generator 8 is driven to switch the secondary battery 7 from the ACG 43. Is supplied with electric power, and the secondary battery 7 is charged. When the required output increases, electric power is supplied from the ACG 43 to the electric motor 5.

  As described above, the engine generator 8 supplies power from the ACG 43 to the secondary battery 7 and the electric motor 5 when the required output is large or the potential of the secondary potential is low. When power supply to the secondary battery 7 and the electric motor 5 is not necessary, the internal combustion engine 41 may be driven in an idle state or may be stopped.

  In the stationary state, the electric vehicle 1 can drive the engine generator 8 in the mounted state and supply electric power to the outside. Electric power is supplied from the external output connector 54 as a 100 V single-phase alternating current.

  When the engine generator 8 is in the mounted state, the vehicle body side fuel tank 23 is connected to the generator side fuel tank 48 via the vehicle body side fuel system connector 33 and the generator side fuel system connector 53. The fuel capacity that can be supplied increases. For this reason, the engine generator 8 can sufficiently contribute to extending the cruising distance of the electric vehicle 1. On the other hand, when the engine generator 8 is not mounted, since the vehicle body side fuel tank 23 is separated from the engine generator 8, the engine generator 8 is compact and lightweight, and is easy to move.

  When the engine generator 8 is mounted, the generator side exhaust passage 55 is connected to the vehicle body side exhaust passage 22 via the generator side exhaust system connector 52 and the vehicle body side exhaust system connector 32. Thereby, even if the engine generator 8 is mounted on the vehicle body 2, the exhaust gas from the internal combustion engine 41 does not flow into the passenger compartment, but is released into the atmosphere avoiding the passenger compartment. Further, since the vehicle body side silencer 24 is provided in the vehicle body side exhaust passage 22, the noise reduction effect is further enhanced in the mounted state. On the other hand, when the engine generator 8 is not mounted, the vehicle body side exhaust passage 22 is separated from the engine generator 8, so that the engine generator 8 is compact and lightweight and can be easily moved.

  Further, by operating the vehicle body side exhaust switching valve 65 and flowing the exhaust gas to the vehicle body side heat exchanger 25 in the branch passage 64, the heat quantity of the exhaust gas can be used for heating the vehicle compartment or the defroster. At this time, the generator-side exhaust switching valve 79 is switched, and the exhaust gas bypasses the generator-side silencer 76 and flows through the bypass passage 78, thereby suppressing the temperature decrease of the exhaust gas in the generator-side silencer 76. Thus, the amount of heat supplied to the vehicle body side heat exchanger 25 increases. The generator-side exhaust switching valve 79 is controlled by the generator-side ECU 45 so that the exhaust gas flows into the bypass passage 78 when the engine generator 8 is mounted, and the exhaust gas flows to the generator-side silencer 76 when not mounted. You may make it flow.

  The engine generator 8 can be supplied with gaseous fuel via the first gaseous fuel connector 92 or the second gaseous fuel connector 93 in the mounted state and the non-mounted state, and can drive the internal combustion engine 41 with the gaseous fuel. Thereby, when there is no supply of liquid fuel or when the supply amount of gaseous fuel is large relative to the liquid fuel, the engine generator 8 uses the city gas, LP gas, and cassette cylinder 98 to change the internal combustion engine 41. It can be driven and power can be supplied to the outside. Thus, since the engine generator 8 selectively uses various fuels to generate electric power, it can generate electric power even in the event of a disaster or a situation where a specific fuel such as a remote area cannot be used.

  The engine generator 8 according to this embodiment can be detached from the vehicle body 2. Therefore, when the electric vehicle 1 is used for low-distance traveling, the weight of the vehicle body 2 can be reduced by lowering the engine generator 8 from the vehicle body 2, and the power consumption required for traveling can be reduced. Further, the engine generator 8 can be removed and brought into a place where the electric vehicle 1 cannot enter, so that the versatility is high.

  The engine generator 8 can be used as a power source for other vehicles. The other vehicle may be an electric two-wheeled vehicle, an electric three-wheeled vehicle, an electric four-wheeled vehicle or the like using an electric motor as a drive source. These electric vehicles do not have a power source (battery) and may use the engine generator 8 as a main power source, or have a power source and use the engine generator 8 as an auxiliary power source. May be used. For example, as an electric motorcycle that can be mounted on the electric vehicle 1, an electric motorcycle that has an electric motor but does not have an electric power source may be prepared. When the electric motorcycle is driven, the engine generator 8 of the electric vehicle 1 is used. By sharing the power source between the electric vehicle 1 and the electric motorcycle, the entire weight including the electric vehicle 1 and the electric motorcycle can be reduced.

  The internal combustion engine 41 of the engine generator 8 is separated from the vehicle body side exhaust passage 22 and the vehicle body side fuel tank 23 in a non-mounted state, and is configured as a compact and lightweight device. Thereby, the portability of the engine generator 8 is improved. The engine generator 8 in the non-mounted state is driven at a lower engine speed than in the mounted state, and noise is suppressed. Therefore, even when the vehicle body side silencer 24 is separated, sufficient silence can be realized. In other words, in a mounted state where high output is required, the engine generator 8 is driven in a state where the engine speed is high. Therefore, the vehicle body side silencer 24 has a higher silencing effect than the generator side silencer 76, and the engine Suppresses noise that increases as the rotational speed increases.
