When the second power supply 141 loses power due to the self-discharge of the second power supply 141, if the second power supply 141 is not replenished in time, the second power supply 141 will not be able to provide a straddle-type electric motorcycle. 100 starts the required energy, and then influences straddle type electric motorcycle 100 and can't start. In this application, the vehicle controller 151 can protect the second power supply 141 against power loss. Specifically, as shown in FIG. 7 , the vehicle controller 151 is connected to the second power supply 141 and can monitor the state parameters of the second power supply 141. The vehicle controller 151 includes a first monitoring mode and a second monitoring mode, which can be used in different In the monitoring mode, a corresponding control action is taken to supplement power to the second power supply 141 . The state parameter may be selected from one or more of voltage, current, and state of charge. As an implementation, the vehicle controller 151 uses 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 power-off or power-off, the vehicle controller 151 enters the first monitoring mode, and the vehicle controller 151 continues to detect the second power supply 141 within the set detection time. voltage, when the voltage of the second power supply 141 is lower than the first preset parameter, the vehicle controller 151 sends a request signal to the power management device 135 and drives the transformer device 142 to work, and the power management device 135 receives the request signal and enters into operation state, the power management device 135 reawakens the first power supply 131 to make the first power supply 131 enter the working state, the output voltage of the first power supply 131 is transformed by the transformer device 142 and then charged to the second power supply 141, and within the preset charging time Continue to charge the second power supply 141 until the preset charging time is over, the vehicle controller 151 sends a signal to stop charging to the power management device 135, and the power management device 135 makes the first power supply 131 stop the output voltage of the transformer 142. When the straddle-type electric motorcycle 100 is in a static state (the static state means that the straddle-type electric motorcycle 100 has not been used for a long time), the vehicle controller 151 enters the second monitoring mode. It should be noted that, The vehicle controller 151 is connected with a timer, the timer receives the power supply from the second power supply 141, and is in working condition all the time, the timer will wake up the vehicle controller 151 every time through the first time, so that the vehicle controller 151 Work, the vehicle controller 151 after waking up detects the voltage of the second power supply 141, when the voltage of the second power supply 141 is lower than the first preset parameter, the vehicle controller 151 sends a request signal to the power management device 135 and Drive the transformer device 142 to work, the power management device 135 receives the request signal and enters the working state, the power management device 135 reawakens the first power source 131 to make the first power source 131 enter the working state, and the voltage output by the first power source 131 is passed through the transformer device 142 is charged to the second power supply 141 after being transformed, and until the preset charging time is over, the vehicle controller 151 sends a signal to stop charging to the power management device 135, and the power management device 135 controls the first power supply 131 to stop outputting voltage to the transformer device 142 .

It can be understood that, in the above two monitoring modes, during the charging process of the second power source 141, the vehicle controller 151 continuously detects the voltage of the second power source 141, and when the voltage of the second power source 141 is within the preset charging period When the second preset parameter is reached, the vehicle controller 151 sends a signal to stop charging to the power management device 135 , and the power management device 135 makes the first power source 131 stop the output voltage of the transformer device 142 . The first preset parameter and the second preset parameter can be set according to the working parameters of the second power supply 141. As an implementation, the first preset parameter corresponds to the second power supply 141 and can provide the straddle-type electric motorcycle 100 to start. For the required voltage, the second preset parameter corresponds to the voltage of the second power supply 141 in a fully charged state, and the second preset parameter is greater than the first preset parameter. In this embodiment, the setting of the preset charging time is equal to the first time. Such a setting can enable the vehicle controller 151 to detect the voltage of the second power supply 141 again after the charging of the second power supply 141 is completed. If the voltage of the second power source 141 is still lower than the first preset parameter, the first power source 131 can be allowed to charge the second power source 141 again, without the need for the power management device 135 to wake up the first power source 131 again, which can reduce the power consumption of the first power source 131 Power loss, effectively improve the efficiency of the circuit. The control system 15 in this embodiment monitors the state of the second power supply 141 and controls accordingly, which can effectively prevent the situation that the straddle-type electric motorcycle 100 cannot start caused by the power loss of the second power supply 141, and is beneficial to prolong the second power supply. The service life of the power supply 141 is improved, and the power consumption loss of the straddle type electric motorcycle 100 is reduced. In addition, the control system 151 can communicate with the mobile terminal and/or the cloud server through the vehicle controller 151 . When the straddle-type electric motorcycle 100 is in a stationary 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 the control system 15 When the state data of the straddle-type electric motorcycle 100 is transmitted 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 .

During the charging process of the straddle-type electric motorcycle 100, there are cases where the user forgets that the straddle-type electric motorcycle 100 is in the charging state, and forcibly drives the straddle-type electric motorcycle 100 to travel and drags the charging assembly 300. This situation will cause great hidden danger to the charging safety of the straddle type electric motorcycle 100, and will also cause damage to the straddle type electric motorcycle 100 or the charger 31 when it is serious, so it is necessary to check the current straddle type electric motorcycle 100. Whether the charging assembly 300 is connected is detected and controlled, so that the straddle-type electric motorcycle 100 cannot be driven while being charged. In the prior art, national standard AC charging guns are mostly used for charging connection, and national standard AC charging guns use CC signals for connection identification. CC signals are connection confirmation signals in vehicle charging, and it is determined whether the charger 31 is Already connected with straddle type electric motorcycle 100. However, the national standard AC charging gun 32 needs a corresponding charging pile as the charger 31. At present, the number of charging piles is small, the area coverage is narrow, and the convenience of use is poor, which cannot meet the daily charging needs of users. For the straddle type electric motorcycle 100 It is not the best charging method for users. In this embodiment, the charger 31 corresponding to the charging gun 32 can be directly connected to a household charging socket or a charging socket connected to the mains, which is more convenient and faster for users while ensuring charging safety.

In this embodiment, when charging the straddle-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 terminal 327 of the charging gun 32 is electrically connected to the vehicle controller 151, and the electrical signal is transmitted to the vehicle controller 151 through the detection terminal 327, and the vehicle controller 151 acquires And detect the electric signal, to determine whether the charging gun 32 is connected with the charging interface 132, if it is determined that the charging gun 32 is connected with the charging interface 132, the vehicle controller 151 controls the straddle-type electric motorcycle 100 to enter the charging state, and in the charging state, the motor 133 has no driving force output, so that the straddle-type electric motorcycle 100 cannot be driven. For example, when the vehicle controller 151 determines that the charging gun 32 is connected to the charging interface 132, the vehicle controller 151 can transmit a corresponding charging command to the motor controller 134 through the communication bus 152 (representing that the straddle-type electric motorcycle 100 enters charging). State), and then the motor controller 134 responds to the charging instruction without torque output, so that the motor 133 has no driving force output. After charging is completed, the user pulls out the charging gun 32 to separate the charging gun 32 from the charging interface 132, the connection between the detection terminal 327 and the vehicle controller 151 is disconnected, and the vehicle controller 151 no longer receives the connection signal. Control the straddle-type electric motorcycle 100 to leave the charging state. As an implementation, one end of the detection terminal 327 is connected to the wake-up terminal 321, and the wake-up terminal 321 can output a high-level signal, so that the wake-up terminal 321 transmits a high-level signal to the detection terminal 327, and the vehicle controller 151 is set to be high. The effective detection method of the level signal, when charging, when the vehicle controller 151 obtains the electrical signal transmitted by the detection terminal 327 as a high-level signal, it is determined that the charging gun 32 is connected to the charging interface 132, and the vehicle controller 151 controls The straddle-type electric motorcycle 100 enters the charging state. A prerequisite for this implementation is that the charger 31 needs to be connected to an external power source, so that the wake-up terminal 321 has a high-level signal input.

As another implementation, the detection terminal 327 of the charging gun 32 is connected to the ground terminal 326 of the charging gun 32. At this time, the ground terminal 326 transmits a low-level signal to the detection terminal 327. The effective detection method of the level signal is to determine that the charging gun 32 is connected to the charging interface 132 when the vehicle controller 151 obtains the low-level signal, and the vehicle controller 151 controls the straddle-type electric motorcycle 100 to enter the charging state. In this way, when the charging gun 32 is connected to the charging interface 132, the vehicle controller 151 can obtain the low-level signal transmitted by the detection terminal 327, and the vehicle controller 151 can control the crossover without connecting the charger 31 to an external power supply. The ride-on electric motorcycle 100 enters the charging state to avoid the charging gun 32 from being dragged. The above two implementation methods all use the ports carried on the charging gun 32 - the wake-up terminal 321, the ground terminal 326, the detection terminal 327, etc., for example, the wake-up terminal 321 is connected to the detection terminal 327, or the ground terminal 326 is connected to the detection terminal 327 Connection, that is, through other ports on the charging gun 32 as the input of electrical signals, without adding redundant ports to transmit detection signals, the connection detection of the charging gun 32 can be established when the straddle-type electric motorcycle 100 is charging, which is beneficial to the charging. The charging protection of the straddle type electric motorcycle 100 can also control the manufacturing cost of the charging gun 32 at the same time.

In addition, the second limiting end 1381f can rotate relative to the battery box 138, and the second limiting end 1381f includes a first position and a second position relative to the battery box 138. The separating device 1381 also includes a control switch 1381c, which is connected to the second position. The two limit ends 1381f are connected. As shown in Figure 12, the second limiting end 1381f is connected to the second limiting hole at the first position, and the second limiting end 1381f is separated from the second limiting hole at the second position, and the second limiting end 1381f responds to the control of the control switch 1381c, when the control switch 1381c rotates, the second limit end 1381f also rotates correspondingly, the second limit end 1381f rotates into the second limit hole 1383, and the second limit hole 1383 The second limiting end 1381f is limited and fixed, so that one end of the first plate 1381a is fixed on the battery box 138.

In the first state, the first limiting end 1381d and the second limiting end 1381f are engaged together. On the first limiting hole, such arrangement enables the third limiting end 1381e to receive the first limiting end 1381d when the first plate 1381a is under the pressure of the first chamber, preventing the first limiting end 1381d from Friction occurs between the first limiting holes, resulting in loosening.

The cooling fluid flows through the motor controller 134, the motor 133, and the water pump 163 sequentially from the radiator 161, and finally the cooling fluid is transferred to the radiator 161 by the water pump 163 to form a circulation cycle of the cooling fluid, which can control the motor controller 134 and the motor 133. Water cooling. In this embodiment, the motor controller 134 has priority over the motor 133 to participate in the cooling cycle. The reason for this setting is that the temperature resistance of the motor controller 134 is lower than that of the motor 133, and its heat resistance is poor. Therefore, the motor controller 134 is placed closer to the heat dissipation Device 161 is arranged. The present application uses water cooling to cool the motor 133 and the motor controller 134, which can effectively control the temperature of the high-power and high-speed motor 133, and can also reduce the internal temperature of the motor controller 134.

The radiator 161 is vertically arranged with the ground, the cooling liquid flows on the blades of the radiator 161, and the cooling liquid is contacted with the ambient air by the radiator 161, which can The contact area between the cooling liquid and the ambient air is effectively increased, so that the utilization rate of the windward side of the radiator 161 is the highest, and 100% windward effect can be achieved, so that the cooling liquid can fully contact the ambient air on the surface 161 of the radiator. During the running of the straddle-type electric motorcycle 100, a large amount of ambient air flows in from the front part 400 of the straddle-type electric motorcycle 100, flows through and passes through the radiator 161, so that the cooling air flowing on the surface of the radiator 161 The liquid is in contact with the ambient air, and the ambient air removes most of the heat from the coolant, thereby cooling the coolant.

As an implementation, the second heat dissipation pipe 1332 can be arranged between the stator winding of the motor 133 and the Between the shells of the motor 133, there is a gap between the second heat dissipation pipe 1332 and the stator winding, so the heat can only be transferred through air between the stator winding and the second heat dissipation pipe 1332, and the efficiency of heat transfer in this way is extremely low, so The gap between the stator winding and the second heat dissipation pipe 1332 is filled by glue filling, and the heat dissipation performance of the motor 133 can be greatly improved by using glue with good thermal conductivity. As an 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 higher durability. Good, but also easy to process.

The water pump 163 is used to pressurize the coolant to provide power for the entire water-cooling cycle circuit to ensure that the coolant can flow in the entire water-cooling cycle circuit. The water pump 163 sends the coolant to the other side of the radiator 161 through the fifth pipeline 1645 At one end, due to the long distance between the water pump 163 and the radiator 161, compared with the first pipeline 1641, the second pipeline 1642, the third pipeline 1643 and the fourth pipeline 1644, the arrangement length of the fifth pipeline 1645 is the longest. Long, in order to prevent the fifth pipeline 1645 from shaking when the straddle-type electric motorcycle 100 is running, the fifth pipeline 1645 is fixedly installed on the frame 11 through a limit clip, which can hold the fifth pipeline 1645 restricts the horizontal and vertical directions to prevent the fifth pipeline 1645 from shaking. In this embodiment, the water pump 163 can selectively operate according to the internal temperature of the motor 133 or the motor controller 134, that is, the water pump 163 adjusts the increased pressure on the coolant according to the temperature of the motor 133 and/or the motor controller 134, thereby adjusting the cooling The speed at which the liquid flows in the entire circulation loop, this setting can effectively optimize the heat dissipation performance of the heat dissipation system 16, which is conducive to saving energy and avoiding unnecessary energy consumption in the heat dissipation process.
