In this embodiment, the second power supply 141 can provide the electric energy required for the whole vehicle controller 151 and the starting switch of the straddle-type electric motorcycle 100, so as to prevent the occurrence of power shortage caused by dark current consumption or self-discharge of the second power supply 141 in the electric devices of the straddle-type electric motorcycle 100, and when the power shortage occurs in the second power supply 141, the second power supply 141 cannot provide the energy required for starting the straddle-type electric motorcycle 100 without timely supplementing the power to the second power supply 141, thereby affecting the incapability of starting the straddle-type electric motorcycle 100. In the present application, the vehicle controller 151 can perform the power shortage protection on the second power supply 141. Specifically, as shown in fig. 7, the vehicle controller 151 is connected to the second power supply 141, so as to monitor a state parameter of the second power supply 141, where the vehicle controller 151 includes a first monitoring mode and a second monitoring mode, and is capable of performing corresponding control actions in different monitoring modes to supplement power to the second power supply 141. The state parameter may be one or more of voltage, current, and state of charge, and as an implementation manner, the vehicle controller 151 uses the voltage as a monitoring target to detect the second power supply 141.

When the straddle-type electric motorcycle 100 is switched from the running state to the power-off or power-down state, the whole vehicle controller 151 enters a first monitoring mode, the whole vehicle controller 151 continuously detects the voltage of the second power supply 141 in a set detection time, when the voltage of the second power supply 141 is lower than a first preset parameter, the whole vehicle controller 151 sends a request signal to the power management device 135 and drives the voltage transformation device 142 to work, the power management device 135 receives the request signal and enters an operating state, the power management device 135 wakes the first power supply 131 again to enable the first power supply 131 to enter the operating state, the output voltage of the first power supply 131 is charged to the second power supply 141 after being transformed by the voltage transformation device 142, and the second power supply 141 is continuously charged in a preset charging time period until the preset charging time period is ended, the whole vehicle controller 151 sends a stop charging signal to the power management device 135, and the power management device 135 enables the first power supply 131 to stop the voltage transformation device 142 from outputting the voltage. When the straddle-type electric motorcycle 100 is in a rest state (the rest state is represented as a state that the straddle-type electric motorcycle 100 is not used for a long time), the whole vehicle controller 151 enters a second monitoring mode, a timer is connected to the whole vehicle controller 151 and receives power supplied from the second power supply 141, the timer is in an operating state at all times, the whole vehicle controller 151 is woken up every time the timer passes a first time to enable the whole vehicle controller 151 to operate, the woken-up whole vehicle controller 151 detects the voltage of the second power supply 141, when the voltage of the second power supply 141 is lower than a first preset parameter, the whole vehicle controller 151 sends a request signal to the power management device 135 and drives the transformer 142 to operate, the power management device 135 receives the request signal and enters an operating state, the power management device 135 wakes the first power supply 131 again to enable the first power supply 131 to enter the operating state, the voltage output by the first power supply 131 is transformed by the transformer 142 and then charged to the second power supply 141 until the preset charging time is ended, the whole vehicle controller 151 sends a stop charging signal to the power management device 135, and when the voltage of the second power supply 141 is lower than a first preset parameter, the voltage of the whole vehicle controller 135 is controlled by the power management device 135 to stop outputting the voltage to the transformer 142.

It can be understood that in the above two monitoring modes, during the charging process of the second power supply 141, the vehicle controller 151 continuously detects the voltage of the second power supply 141, and when the voltage of the second power supply 141 reaches the second preset parameter within the preset charging period, the vehicle controller 151 sends a charging stop signal to the power management device 135, and the power management device 135 makes the first power supply 131 stop the voltage output by the voltage transformation device 142. The first preset parameter and the second preset parameter can be set according to the working parameter of the second power supply 141, and as an implementation manner, the first preset parameter corresponds to the second power supply 141 and can provide the voltage required for starting the straddle-type electric motorcycle 100, the second preset parameter corresponds to the voltage of the second power supply 141 in the full-power state, and the second preset parameter is greater than the first preset parameter. In this embodiment, the preset charging duration is set to be equal to the first time, and after the charging of the second power supply 141 is completed, the whole vehicle controller 151 can detect the voltage of the second power supply 141 again, if the voltage of the second power supply 141 is still lower than the first preset parameter, the first power supply 131 can be charged to the second power supply 141 again, and the power management device 135 is not required to wake up the first power supply 131 again, so that the electric quantity loss of the first power supply 131 can be reduced, and the working efficiency of the circuit is effectively improved. The control system 15 in this embodiment monitors the state of the second power supply 141 and controls the second power supply 141 accordingly, so that the situation that the straddle-type electric motorcycle 100 cannot be started due to the power shortage of the second power supply 141 can be effectively prevented, the service life of the second power supply 141 can be prolonged, and the power consumption loss of the straddle-type electric motorcycle 100 can be reduced. In addition, the control system 151 can be connected with the mobile terminal and/or the cloud server through the whole vehicle controller 151 in a communication manner. When the straddle-type electric motorcycle 100 is in the standing state, the control system 15 can transmit the state data of the straddle-type electric motorcycle 100 to the mobile terminal and/or the cloud server every first time, so that when the control system 15 transmits the state data of the straddle-type electric motorcycle 100 to the mobile terminal and/or the cloud server, the control system 15 can synchronously acquire the current parameters of the second power supply 141, and the state data can represent the current state of the straddle-type electric motorcycle 100.

In the process of charging the saddle-ride type electric motorcycle 100, there are cases where the user forgets that the saddle-ride type electric motorcycle 100 is in a charged state and forcibly drives the saddle-ride type electric motorcycle 100 to travel and drag the charging assembly 300, and this case causes a great hidden danger to the safety of charging the saddle-ride type electric motorcycle 100, and also damages the saddle-ride type electric motorcycle 100 or the charger 31 when serious, so that it is necessary to detect and control whether the current saddle-ride type electric motorcycle 100 is connected to the charging assembly 300, so that the saddle-ride type electric motorcycle 100 cannot be driven to travel in the charged state. In the prior art, a national standard ac charging gun is used for charging connection, the national standard ac gun is used for connection identification by adopting a CC signal, the CC signal is a connection confirmation signal in vehicle-mounted charging, and whether the charger 31 is connected with the straddle-type electric motorcycle 100 is determined by detecting a voltage condition of the CC signal. However, the national standard ac charging gun 32 needs corresponding charging piles as the charger 31, and the number of charging piles is small, the coverage area is narrow, the convenience of use is poor, the daily charging requirement of the user cannot be met, and the charging mode is not the best charging mode for the user of the straddle type electric motorcycle 100. The charger 31 corresponding to the charging gun 32 in the present embodiment can be directly connected to a household or a charging socket connected to the mains, so that the charging safety is ensured, and the user can more conveniently and quickly use the charging socket.

In the present embodiment, when charging the saddle-ride type electric motorcycle 100, the charging gun 32 can also provide a connection signal to the control system 15, and the control system 15 determines whether the charging gun 32 is connected to the charging interface 132 according to the connection signal. Specifically, the charging gun 32 is connected to the charging interface 132, the detection end 327 of the charging gun 32 is electrically connected to the vehicle controller 151, an electric signal is transmitted to the vehicle controller 151 through the detection end 327, the vehicle controller 151 obtains and detects the electric signal in real time to determine whether the charging gun 32 is connected to the charging interface 132, if it is determined that the charging gun 32 is connected to the charging interface 132, the vehicle controller 151 controls the straddle electric motorcycle 100 to enter a charging state, and no driving force is output from the motor 133 in the charging state, so that the straddle electric motorcycle 100 cannot drive. For example, when the vehicle controller 151 determines that the charging gun 32 is connected to the charging interface 132, the vehicle controller 151 may transmit a corresponding charging command (representing that the straddle-type electric motorcycle 100 enters a charging state) to the motor controller 134 through the communication bus 152, and the motor controller 134 does not have a torque output in response to the charging command, so that the motor 133 does not have a driving force output. When the charging is completed, the user pulls out the charging gun 32, so that the charging gun 32 is separated from the charging interface 132, the connection between the detection end 327 and the whole vehicle controller 151 is disconnected, the whole vehicle controller 151 does not receive the connection signal any more, and the straddle-type electric motorcycle 100 is controlled to be separated from the charging state. As an implementation manner, one end of the detection end 327 is connected to the wake-up end 321, the wake-up end 321 can output a high-level signal, so that the wake-up end 321 transmits the high-level signal to the detection end 327, the whole vehicle controller 151 sets an effective detection manner of the high-level signal, when the whole vehicle controller 151 obtains that the electric signal transmitted by the detection end 327 is the high-level signal during charging, the charging gun 32 is determined to be connected with the charging interface 132, and the whole vehicle controller 151 controls the straddle-type electric motorcycle 100 to enter a charging state.

As another implementation manner, the detection end 327 of the charging gun 32 is connected with the ground end 326 of the charging gun 32, at this time, the ground end 326 transmits a low-level signal to the detection end 327, when the vehicle controller 151 obtains the low-level signal through the effective detection manner of the low-level signal during charging, the charging gun 32 is determined to be connected with the charging interface 132, and the vehicle controller 151 controls the straddle-type electric motorcycle 100 to enter the charging state, so that when the charging gun 32 is connected with the charging interface 132, the vehicle controller 151 can obtain the low-level signal transmitted by the detection end 327, the charger 31 does not need to be connected with an external power supply, and the vehicle controller 151 can control the straddle-type electric motorcycle 100 to enter the charging state, so as to avoid the situation that the charging gun 32 is dragged. In both the above two implementation manners, the port carried on the charging gun 32, namely, the wake-up end 321, the ground end 326, the detection end 327, etc., is adopted, for example, the wake-up end 321 is connected with the detection end 327, or the ground end 326 is connected with the detection end 327, that is, other ports on the charging gun 32 are used as the input of the electric signal, so that the connection detection of the charging gun 32 during charging of the straddle electric motorcycle 100 can be established without adding redundant ports to transmit the detection signal, which is beneficial to the charging protection of the straddle electric motorcycle 100, and meanwhile, the manufacturing cost of the charging gun 32 can be controlled.

As shown in fig. 37, the water kettle 162 is provided with a first heat radiation pipe 1341 through which cooling fluid flows in the motor controller 134, and a second heat radiation pipe 1332 through which cooling fluid flows in the motor 133, by which cooling fluid is transferred to the radiator 161 through the heat radiation pipe 164.

In the present embodiment, the motor controller 134 takes part in the cooling cycle in preference to the motor 133, and the reason for this arrangement is that the motor controller 134 is disposed closer to the radiator 161 because the temperature resistance value of the motor controller 134 is lower than that of the motor 133 and the heat resistance is poor. The application uses a water cooling heat dissipation mode to cool the motor 133 and the motor controller 134, can effectively control the temperature of the motor 133 with high power and high rotation speed, and can reduce the internal temperature of the motor controller 134.

During the running of the saddle-ride type electric motorcycle 100, a large amount of ambient air is collected from the front 400 of the saddle-ride type electric motorcycle 100, flows through and passes through the radiator 161, so that the cooling liquid flowing on the surface of the radiator 161 is in contact with the ambient air, and the ambient air takes most of the heat of the cooling liquid away, thereby cooling the cooling liquid.

As an alternative implementation, the cooling liquid is transferred from the second pipeline 1642 to the inside of the motor controller 134, flows inside the motor controller 134 through the first heat dissipation pipeline 1341, flows through the motor controller 134 and then flows to the third pipeline 1643, takes away heat of the motor controller 134, and dissipates heat for the motor controller 134.

The coolant passing through the first heat dissipation pipe 1341 enters the second heat dissipation pipe 1332 through the third pipe 1643, flows inside the motor 133, and removes heat generated inside the motor 133, thereby dissipating heat from the motor 133.

As one implementation, the first heat dissipation pipe 1341 and the second heat dissipation pipe 1332 are made of aluminum alloy, so that the first heat dissipation pipe 1341 and the second heat dissipation pipe 1332 have good corrosion resistance, lighter weight and better durability, and are easy to manufacture and process.
