Description

Technical Field

[0001] The present invention relates to the technical field of power supplies, and in particular to a bidirectional control system for an electric motorcycle charging and inverter integrated power supply. Background Art

[0002] An electric scooter, or electric motorcycle, has a removable battery that powers the scooter. Existing electric scooter batteries typically only have a one-way charging function and cannot reversely supply power to other devices. If the battery needs to be able to discharge, an additional inverter system is required. Therefore, two separate systems are required for charging and discharging: an AC / DC charging system for charging the battery and a DC / AC inverter system for discharging the battery. Different systems must be used for charging and discharging the battery. The addition of a discharge system complicates the internal wiring of the power supply, making it difficult to assemble. Furthermore, the combined size of the two systems increases the size of the battery, making it difficult to use and carry. Summary of the Invention

[0033] Example 1

[0034] Please refer to Figure 1 , Figure 1 The bidirectional control system of the electric motorcycle charging and inverter power supply in this embodiment includes a first charging module 1, a first discharging module 2, an MCU control module 3, a PFC inverter main power module 4, a buck-boost module 5, and a power supply module 6.

[0035] The first charging module 1 is connected to the MCU control module 3 and is used to connect to the charging gun and detect the charging gun's electrical signal parameters. When the charging gun is connected to the first charging module 1, the first charging module 1 detects the charging gun's electrical signal parameters and sends a first charging signal to the MCU control module 3. It should be noted that the electrical signal parameters include the charging gun's power, voltage, and current values.

[0036] The first discharge module 2 is used to connect to the discharge gun. When the discharge gun is connected to the first discharge module 2 , the first discharge module 2 detects the electrical signal parameters of the discharge gun and outputs a first discharge signal to the MCU control module 3 .

[0037] The MCU control module 3 is connected to the first charging module 1 and the first discharging module 2, respectively. The MCU control module 3 is configured to receive a first charging signal and a second discharging signal. When the MCU control module 3 receives the first charging signal, the MCU control module 3 activates the first charging mode to charge the power module 6. When the MCU control module 3 receives the first discharging signal, the MCU control module 3 activates the first discharging mode to discharge the power module 6.

[0038] The PFC inverter main power module 4 is connected to the first charging module 1, the first discharging module 2, the buck-boost module 5, and the MCU control module 3. When the MCU control module 3 is in the first charging mode, the PFC inverter main power module 4 is used to rectify the electrical signal output by the first charging module. The PFC inverter main power module 4 receives the AC power output by the first charging module 1, rectifies the input AC power, and generates DC power, which is then output to the buck-boost module 5. When the MCU control module 3 is in the first discharging mode, the MCU control module 3 controls the PFC inverter main power module 4 to enter the inverter mode, at which point the PFC inverter main power module 4 performs the inverter function. The PFC inverter main power module 4 receives the electrical signal output by the buck-boost module 5, inverts it, and then outputs the electrical signal to the first discharging module 2.

[0039] The buck-boost module 5 is connected to the MCU control module 3, the PFC inverter main power module 4, and the power module 6. Controlled by the MCU control module 3, the buck-boost module 5 adjusts the voltage. When the MCU control module 3 activates the first charging mode, the buck-boost module 5 receives the electrical signal output by the PFC inverter main power module 4 and then steps up or steps down the voltage of the electrical signal. When the MCU control module 3 activates the first charging mode, the buck-boost module 5 receives the electrical signal output by the power module 6 and steps up or steps down the voltage of the signal.

[0040] Preferably, the buck-boost module 5 adopts a DC-DC isolated buck-boost module 5 , which, when in use, realizes electrical isolation between the input and output ends of the buck-boost module 5 , effectively improving the safety of the circuit.

[0041] The power module 6 is connected to the buck-boost module 5 and the MCU control module 3. When the MCU control module 3 activates the first charging mode, it obtains the power information of the power module 6. Then, based on the power information of the power module 6 and the electrical signal parameters of the charging gun, the MCU control module 3 controls the buck-boost module 5 to activate the boost or buck mode, and intelligently adjusts the charging power of the charging gun by controlling the first charging module 1. When the MCU control module 3 activates the first discharging mode, it obtains the power information of the power module 6. Based on the power information of the power module 6 and the electrical signal parameters of the charging gun, the MCU control module 3 controls the buck-boost module 5 to boost or buck the electrical signal output by the power module 6, so that the electric motorcycle charging and reversing power supply bidirectional control system outputs an electrical signal that matches the discharge gun.

[0042] It should be noted that, in the embodiment, the power information includes battery voltage, battery remaining capacity, temperature and fault information. The MCU control module 3 monitors the use status of the power module in real time according to the power information.

[0043] By integrating rectification and inversion into the PFC inverter main power module 4 and integrating boost and buck into the buck-boost module 5, the control system for the electric motorcycle charging and inverter power supply provides both charging and discharging functions while effectively reducing its size. Furthermore, by using the first charging module 1 and the first discharging module 2 to identify the charging and discharging guns, and using the MCU control module 3 to switch between the first charging mode and the first discharging mode, the system becomes more intelligent and efficient.

[0044] Furthermore, the first charging module 1 includes a first charging terminal 11, a charging gun detection module 12, and a charging management module 13. The first charging terminal 11 is connected to the charging gun detection module 12 and the charging management module 13, respectively, and the first charging terminal 11 is used to connect to the charging gun. The charging gun detection module 12 is connected to the first charging terminal 11 and the MCU control module 3. When the charging gun is connected to the first charging terminal 11, the charging gun detection module 12 is used to detect the electrical signal parameters of the charging gun. At the same time, the charging gun detection module 12 sends a first charging signal to the MCU control module 3. The MCU control module 3 starts the first charging mode, obtains the power information of the power module 6, and controls the charging management module 13 based on the power information of the power module 6 and the electrical signal parameters of the charging gun. The charging management module 13 is connected to the first charging terminal 11, and is used to receive the electrical signal from the first charging terminal 11 and regulate the electrical signal of the first charging terminal 11 according to the instructions of the MCU control module 3.

[0045] During actual use, the electrical signal released by the charging gun is output from the first charging terminal 11, and the charging management module 13 receives the electrical signal output from the first charging terminal 11. The charging management module 13 regulates the input electrical signal according to the control instruction of the MCU module and then outputs it.

[0046] The first discharge module 2 includes a first discharge terminal 21, a discharge gun detection module 22, and a discharge management module 23. The first discharge terminal 21 is connected to the discharge gun detection module 22. The first discharge terminal 21 is used to connect to a discharge gun. The discharge gun detection module 22 is connected to the first discharge terminal 21 and the MCU control module 3. When the discharge gun is inserted into the first discharge terminal 21, the discharge gun detection module 22 is used to detect the electrical signal parameters of the discharge gun. At the same time, the discharge gun detection module 22 sends a first discharge signal to the MCU control module 3, causing the MCU control module 3 to activate the first discharge mode. The discharge management module 23 is connected to the first discharge terminal 21 and the MCU control module 3. In the first discharge mode, the discharge management module 23 is used to receive the electrical signal output by the PFC inverter main power module 4 and regulate the electrical signal output by the PFC inverter main power module 4 according to the instructions of the MCU control module 3.

[0047] When the discharge gun detection module 22 detects that a discharge gun has been inserted, it generates a first discharge signal. The MCU control module 3 receives the first discharge signal and initiates the first discharge mode. In the first discharge mode, the MCU control module 3 controls the PFC inverter main power module 4 to enable the inverter function. The MCU control module 3 controls the buck-boost module 5 to enable the boost or buck function, and the power module 6 performs discharge. The discharge signal from the power module 6 is input to the buck-boost module 5, which then boosts or bucks the discharge signal. The PFC inverter main power module 4 receives the electrical signal output by the buck-boost module 5 and inverts it. The discharge management module 23 regulates the electrical signal output by the buck-boost module 5 according to instructions from the MCU control module 3, and outputs the regulated electrical signal to the discharge gun.

[0048] Furthermore, the bidirectional control system for the electric motorcycle charging and inverter power supply also includes a first filter module 9 and a second filter module 10. One end of the first filter module 9 is connected to the first charging module 1 and the second discharging module 8, respectively, and the other end is connected to the PFC inverter main power module 4. The first filter module 9 is used for bidirectional filtering between the first charging module 1 and the first discharging module 2 and the PFC inverter main power module 4. One end of the second filter module 10 is connected to the buck-boost module 5, and the other end is connected to the power module 6. The second filter module 10 is used for bidirectional filtering between the buck-boost module 5 and the power module 6.

[0049] Specifically, when the MCU control module 3 activates the first charging mode, the electrical signal input from the charging gun passes through the first charging module 1 and is then output. The electrical signal output from the first charging module 1 passes through the first filter module 9 and is then input to the PFC inverter main power module 4. The buck-boost module 5 boosts or bucks the electrical signal output from the PFC inverter main power module 4. The second filter module 10 receives and filters the electrical signal output from the buck-boost module 5. Finally, the power module 6 receives the electrical signal output from the second filter module 10. When the MCU control module 3 activates the first discharging mode, the discharge signal from the power module 6 passes through the second filter module 10 and is filtered. The buck-boost module 5 receives the electrical signal output from the second filter module 10. The PFC inverter main power module 4 inverts the electrical signal output from the buck-boost module 5. The first filter module 9 filters the electrical signal output from the PFC inverter main power module 3. The first discharging module 1 receives the electrical signal output from the first filter module 9 and outputs it to the discharge gun.

[0050] Therefore, by providing the first filter module 9 and the second filter module 10, the electrical signals in the circuit are filtered during the charging process and the discharging process respectively, thereby effectively improving the anti-interference performance of the circuit.

[0051] In this example, the first filter module 9 is an AC filter module, and the second filter module 10 is a DC filter module. Both the DC filter module and the AC filter module are common topologies in the prior art, and their specific circuit structures do not involve the improvements of the present invention, so they will not be described here.

[0052] The bidirectional control system of the electric motorcycle charging and inverter power supply also includes a first sampling module 50 and a second sampling module 60. The first sampling module 50 is respectively connected to the first charging module 1, the PFC inverter main power module 4, and the MCU control module 3; the second sampling module 60 is respectively connected to the buck-boost module 5, the power module 6, and the MCU control module 3.

[0053] In the first charging mode, the first sampling module 50 collects the electrical signal output by the first charging module 1 and feeds it back to the MCU control module 3. The second sampling module 60 collects the electrical signal output by the buck-boost module 5 and feeds it back to the MCU control module 3. The MCU control module 3 controls the first charging module 1 to adjust the electrical signal output by the charging gun based on the sampling signals from the first sampling module 50 and the second sampling module 60. In the first discharging mode, the first sampling module 50 collects the electrical signal output by the PFC inverter main power module 4 and feeds it back to the MCU control module 3. The second sampling module 60 collects the electrical signal output by the power module 6 and feeds it back to the MCU control module 3. The MCU control module 3 controls the first discharging module 2 to adjust the output electrical signal based on the sampling signals from the first sampling module 50 and the second sampling module 60.

The first sampling module 50 is used to collect the output electrical signal of the PFC inverter main power module 4 and feed it back to the MCU control module 3.

[0056] It should be noted that the first sampling module 50 and the second sampling module 60 can be implemented by using an operational amplifier differential circuit or a sampling chip.

[0057] In addition, the power module 6 includes a battery pack 61 and a BMS management module 62. The BMS management module 62 is connected to the MCU main control module and the power module 6 respectively. The BMS management module 62 is used to monitor the power information of the power module 6. The power information includes, for example, remaining power, temperature, and fault information.

[0058] The BMS management module 62 is connected to the MCU control module 3 and the power module 6 via CAN or 485 isolated communication. Preferably, the BMS management module 62 is connected to the MCU control module 3 and the power module 6 via CAN communication, which is more efficient than the 485 isolated communication.

[0059] Furthermore, the bidirectional control system of the electric motorcycle charging and inverter power supply also includes a photovoltaic charging module 20. The photovoltaic charging module 20 includes a photovoltaic panel interface 200, a sampling unit 201, a photovoltaic charging MPPT module 202, and a charge and discharge management circuit 203. The photovoltaic panel interface is used to connect to the photovoltaic panel. The sampling unit 201 is connected to the photovoltaic panel interface and the photovoltaic charging MPPT module 202, respectively. The sampling unit 201 is used to collect the electrical signal parameters provided by the photovoltaic panel and then feed them back to the photovoltaic charging MPPT module 202. The photovoltaic charging MPPT module 202 is used to track the maximum power generation voltage and current value of the photovoltaic panel based on the photovoltaic panel's electrical signal parameters, allowing the system to charge the battery at maximum power. The charge and discharge management circuit 203 is connected to the photovoltaic MPPT module and the MCU control module 3, respectively. The charge and discharge management circuit 203 is used to regulate the charging current. During photovoltaic charging, the MCU control module 3 obtains the 6 power supply information of the power module and controls the charge and discharge management circuit 203 to regulate the charging current based on the 6 power supply information of the power module and the electrical signal parameters of the photovoltaic panel.

[0060] When using the photovoltaic charging module 20, a photovoltaic panel is connected to the photovoltaic charging module 20. The MCU control module 3 reads the power supply information of the power module 6. The charge and discharge management circuit 203 outputs the required charging voltage and charging current of the power module 6 based on the remaining power information of the power module 6. The second filter module 10 receives the electrical signal output by the charge and discharge management unit and filters it. Finally, the power module 6 receives the electrical signal output by the second filter module 10 to achieve the charging effect.

[0061] By providing the photovoltaic charging module 20, the charging method of the power module 6 is increased. In a scenario where there is no charging equipment outdoors, the photovoltaic charging module 20 is used to charge the power module 6, so that the charging function can also be realized outdoors.

[0062] Furthermore, the bidirectional control system of the electric motorcycle charging and inverter integrated power supply also includes a low-voltage auxiliary module 30, which is connected to the MCU main control module and the buck-boost module 5 respectively. The low-voltage auxiliary module 30 is used to generate a 12V or 24V low-voltage electrical output. In the actual use scenario of the electric motorcycle, in addition to the normal power supply, a low-voltage activation power supply is also required. During use, the output electrical signal of the buck-boost module 5 is secondary stepped down by the low-voltage auxiliary module 30 to generate a 12V or 24V low-voltage electrical output.

[0063] The bidirectional control system for the electric motorcycle charger and inverter power supply also includes a display and control module 40, which is connected to the MCU control module 3. The display and control module 40 includes an LED display module 41, which is connected to the MCU control module 3. The LED display module 41 is used to display the remaining power of the power module 6, allowing the user to intuitively observe the remaining power.

[0064] When the first charging module 1 is connected to the charging gun, the first charging module 1 detects the electrical signal parameters of the charging gun and sends a first charging signal to the MCU control module 3. The MCU control module 3 receives the first charging signal, obtains the power information of the power module 6, and starts the first charging mode. The MCU control module 3 controls the buck-boost module 5 to start the boost or buck mode based on the electrical signal parameters of the charging gun and the power information of the power module 6. When the supply voltage of the charging gun is greater than the voltage of the power module 6, the buck-boost module 5 is in the buck mode; when the supply voltage of the charging gun is less than the voltage of the power module 6, the buck-boost module 5 is in the boost mode. During charging, the MCU control module 3 controls the first charging module 1 to intelligently adjust the charging power of the charging gun based on the electrical signal parameters of the charging gun and the power information of the power module 6 to adapt to the charging needs of the power module 6, thereby realizing intelligent charging.

[0065] The first charging mode is an intelligent charging mode. Specifically, when the remaining power of the power module 6 is low, the first charging module 1 increases the charging power, charges the power module 6 quickly, and increases the charging rate; when the remaining power of the power module 6 is high, the first charging module 1 limits the charging power, slows down the charging rate, and prevents the power module 6 from overcharging.

[0066] During charging, the output electrical signal of the charging gun is input by the first charging module 1. The first charging module 1 detects the electrical signal parameters of the charging gun and sends a first charging signal to the MCU control module 3. The MCU control module 3 receives the first charging signal, obtains the power information of the power module 6, and activates the first charging mode. Based on the power information of the power module 6 and the electrical signal parameters of the charging gun, the MCU control module 3 sends a control instruction to the first charging module 1. The first charging module 1 adjusts the power of the electrical signal according to the control instruction of the MCU control module 3 and then outputs it to the first filter module 9, which filters the electrical signal output by the first charging module 1. Simultaneously, the PFC inverter main power module 4 receives the electrical signal output by the first filter module 9 and rectifies it. The buck-boost module 5 receives the electrical signal output by the PFC inverter main power module 4 and, according to the instruction of the MCU control module 3, steps up or steps down the voltage of the electrical signal output by the PFC inverter main power module 4. The second filter module 10 receives the electrical signal output by the buck-boost module 5 and filters the electrical signal output by the buck-boost module 5. The power module 6 receives the electrical signal output by the second filter module 10, thereby charging the power module 6. During the charging process, the first sampling module 50 collects the electrical signal output by the first filter module 9 and feeds it back to the MCU control module 3. The second sampling module 60 collects the electrical signal output by the second filter module 10 and feeds it back to the MCU control module 3. The MCU control module 3 monitors the charging process based on the sampled electrical signals of the first sampling module 50 and the sampled signals of the second sampling module 60, so as to send control instructions to the charging management module 13 in real time to regulate the charging electrical signal to prevent the power module 6 from overcharging, overheating, etc.

[0067] When the first discharge module 2 is connected to the discharge gun, it detects the discharge gun's electrical signal parameters and sends a first discharge signal to the MCU control module 3. The MCU control module 3 receives the first discharge signal, obtains power information from the power module 6, and initiates the first discharge mode. Based on the discharge gun's electrical signal parameters and the power information from the power module 6, the MCU control module 3 controls the buck-boost module 5 to activate either boost or buck mode. When the discharge gun's voltage is lower than that of the power module 6, the buck-boost module 5 operates in buck mode; when the discharge gun's voltage is higher than that of the power module 6, the buck-boost module 5 operates in boost mode.

[0068] During the discharge process, the power module 6 begins discharging, and the second filter module 10 receives and filters the electrical signal output by the power module 6. The buck-boost module 5 receives the electrical signal output by the second filter module 10 and, based on instructions from the MCU control module 3, steps up or steps down the electrical signal output by the power module 6. The PFC inverter main power module 4 receives and inverts the electrical signal output by the buck-boost module 5. The first filter module 9 receives and filters the electrical signal output by the PFC inverter main power module 4. The electrical signal output by the first filter module 9 is then sent to the discharge gun, thereby achieving external discharge.

[0069] During the discharge process, the first sampling module 50 collects the electrical signal output by the PFC inverter main power module 4 and feeds it back to the MCU control module 3. The second sampling module 60 collects the electrical signal output by the power module 6 and feeds it back to the MCU control module 3. The MCU control module 3 controls the discharge management module 23 to regulate the discharge current based on the sampling signals from the first sampling module 50 and the second sampling module 60.

[0072] The second charging module 7 is connected to the MCU control module 3 and is used to connect to a mains socket. When the mains socket is connected to the second charging module 7, the second charging module 7 detects the mains voltage and outputs a charging interlock signal to the MCU control module 3.

[0073] The second charging module 7 is connected to the MCU control module 3 , and the second discharging module 8 is used to be connected to the mains plug. When the mains plug is connected to the second discharging module 8 , the second discharging module 8 outputs a discharge interlock signal to the MCU control module 3 .

[0074] The MCU control module 3 is connected to the second charging module 7 and the second discharging module 8, respectively. The MCU control module 3 is configured to receive a charging interlock signal and a discharging interlock signal. When the MCU control module 3 receives the charging interlock signal, the MCU control module 3 activates the second charging mode; when the MCU control module 3 receives the discharging interlock signal, the MCU control module 3 activates the second discharging mode.

[0075] The PFC inverter main power module 4 is connected to the second charging module 7, the second discharging module 8, the buck-boost module 5, and the MCU control module 3. When the MCU control module 3 is in the second charging mode, the PFC inverter main power module 4 receives the electrical signal output by the second charging module 7 and performs rectification. When the MCU control module 3 is in the second discharging mode, the PFC inverter main power module 4 receives the electrical signal output by the buck-boost module 5 and performs inversion.

[0076] The buck-boost module 5 is connected to the PFC inverter main power module 4, the MCU control module 3, and the power module 6. When the MCU control module 3 is in the first charging mode, the buck-boost module 5 receives the electrical signal output by the PFC inverter main power module 4 and steps down the voltage of the signal. When the MCU module is in the second discharging mode, the buck-boost module 5 receives the electrical signal output by the power module 6 and steps up the voltage of the signal.

[0077] The power module 6 is connected to the buck-boost module 5 and the MCU control module 3. When the MCU control module 3 activates the second charging mode, it obtains power information from the power module 6 and regulates the charging power based on the power information and the mains voltage, enabling the power module 6 to charge in a low-power, slow-charging manner. When the MCU control module 3 activates the second discharging mode, the power module 6 begins discharging.

[0078] In this example, the second charging module 7 includes a second charging terminal 71, a charging interlock module 72 and a charging management module 13. The second charging terminal 71 is connected to the charging interlock module 72 and the charging management module 13 respectively, and the second charging terminal 71 is used to connect to the mains socket strip. When the second charging terminal 71 is connected to the mains socket strip, the charging interlock module 72 detects the voltage of the mains and sends a charging interlock signal to the MCU control module 3. The MCU control module 3 receives the charging interlock signal and then turns on the second charging mode. In the second charging mode, the MCU control module 3 obtains the power information of the power module 6. The MCU control module 3 controls the charging management module 13 to adjust the charging voltage according to the mains voltage and the power information of the power module 6, so that the mains voltage outputs a suitable charging voltage after passing through the charging management module 13.

[0079] The second discharge module 8 includes a second discharge terminal 81, a discharge interlock module 82, and a discharge management module 23. The second discharge terminal 81 is connected to the discharge interlock module 82 and the discharge management module 23. The second discharge terminal 81 is used to connect to a mains power plug. When the mains power plug is connected to the second discharge terminal 81, the discharge interlock module 82 sends a discharge interlock signal to the MCU control module 3. The discharge management module 23 is connected to the second discharge terminal 81 and the MCU module. The discharge management module 23 is used to control the discharge current according to instructions from the MCU control module 3.

[0080] When charging, the second charging terminal 71 is connected to the mains socket, and the charging interlock module 72 detects the voltage of the mains and sends a charging interlock signal to the MCU control module 3. After receiving the charging interlock signal, the MCU control module 3 turns on the second charging mode. It should be noted that the second charging mode is a constant voltage slow charging mode. In the second charging mode, the MCU control module 3 obtains the power information of the power module 6 to detect the usage status of the power module 6. Then the MCU control module 3 sends an instruction to the charging management module 13 based on the mains voltage and the power information of the power module 6, and the charging voltage is adjusted by the charging management module 13, so that the power module 6 is slowly charged in a constant voltage and low power manner to avoid excessive charging power causing the temperature of the power module 6 to be too high.

[0081] The second charging module 7 receives the mains current and regulates it before outputting it. The first filter module 9 receives the electrical signal output by the second charging module 7 and filters it. The PFC inverter main power module 4 receives the electrical signal output by the first filter module 9 and rectifies it into direct current. The buck-boost module 5 receives the electrical signal output by the PFC inverter main power module 4 and steps down its voltage. The second filter module 10 receives the electrical signal output by the PFC inverter main power module 4 and filters it. The power supply module 6 receives the electrical signal output by the second filter module 10, thereby achieving the charging effect. In this example, the second charging terminal 71 is a national standard three-pin plug.

[0082] During the charging process, the first sampling module 50 collects the electrical signal output by the first filtering module 9 and then feeds it back to the MCU control module 3. The second sampling module 60 collects the electrical signal output by the second filtering module 10 and then feeds it back to the MCU control module 3. The MUC control module controls the charging management module 13 to regulate the input electrical signal based on the sampling signals from the first sampling module 50 and the second sampling module 60.

[0083] During discharge, the mains plug is plugged into the second discharge terminal 81. The discharge interlock module 82 detects the mains plug connection and sends a discharge interlock signal to the MCU control module 3. The MCU control module 3 starts the second charging mode after receiving the discharge interlock signal.

[0084] The power module 6 discharges, and the second filter module 10 receives and filters the electrical signal released by the power module 6. The buck-boost module 5 receives the electrical signal output by the second module and boosts the electrical signal output by the second filter module 10. The PFC inverter main power module 4 receives and inverts the electrical signal output by the buck-boost module 5. The first filter module 9 receives and filters the electrical signal output by the PFC inverter main power module 4. The discharge management module 23 receives the electrical signal output by the first filter module 9, adjusts the electrical signal output by the first filter module 9 according to the instructions of the MCU control module 3, and then outputs it to the mains power plug.

[0085] During the discharge process, the second sampling module 60 collects the electrical signals released by the power module 6 and feeds them back to the MCU control module 3. The first sampling module 50 collects the electrical signals output by the PFC inverter main power module 4 and feeds them back to the MCU control module 3. The MCU control module 3 controls the discharge process based on the sampling signals collected by the first sampling module 50 and the second sampling module 60.

[0086] In this example, the second discharge end 81 is a national standard five-hole charging socket to meet the plug-in requirements of two-prong plugs and three-prong plugs.

[0087] The display and control module in this embodiment differs from the display and control module 40 in the first embodiment in that it also includes a control button 42. Control button 42 is connected to the MCU control module 3 and is used to manually switch the charging rate. When in the second charging mode, pressing control button 42 sends a fast-charge signal to the MCU control module 3, which in turn controls the charge management module 13 to remove the charging current limit, thereby increasing the charging speed.

[0088] Example 3

[0089] Please refer to Figure 3 , Figure 3 This is a block diagram of the control system of the electric motorcycle charging and inverter power supply in this embodiment. The difference between this embodiment and the first embodiment is that the bidirectional control system of the electric motorcycle charging and inverter power supply in this embodiment further includes a second charging module 7 and a second discharging module 8.

[0090] In this example, the second charging module 7 includes a second charging terminal 71 and a charging interlock module 72, and the second discharging module 8 includes a second discharging terminal 81 and a discharging interlock module 82. The second charging terminal 71 is connected to the charging interlock module 72 and the charging management module 13. The charging interlock module 72 is connected to the MCU control module. The second discharging module 8 includes a second discharging terminal 81 and a discharging interlock module 82. The second discharging terminal 81 is connected to the discharging interlock module 82 and the MCU control module. The discharging interlock module 82 is connected to the MCU control module.

[0091] In this example, by adding a second charging module 7 and a second discharging module 8, the system has two charging modes and two discharging modes. The first charging module 1 allows the system to be charged using a charging gun, while the second charging module 7 allows the system to be charged using a standard national plug. During charging, users can choose either method based on the actual usage scenario, increasing the choice of charging methods.

[0092] Through the first discharge module 2, the system can be charged externally through a discharge gun, and through the second discharge module 8, the system can be discharged externally through a national standard mains socket, thereby providing multiple discharge modes.

[0093] In actual use, when a charging gun is needed for charging, the charging gun is connected to the first charging module 1. The first charging module 1 detects the electrical signal parameters of the charging gun and sends a first charging signal to the MCU control module 3. The MCU control module 3 activates the first charging mode. The specific process of the first charging mode is the same as that in Example 1 and is not repeated here.

[0094] When discharging with a discharge gun is required, the discharge gun is connected to the first discharge module 3. The first discharge module 3 detects the electrical signal parameters of the discharge gun and sends a first discharge signal to the MCU control module 3. The MCU control module 3 receives the first discharge signal and then activates the first discharge mode. The specific process of the first discharge mode is the same as that in Example 1 and is not further described here.

[0095] When charging with AC power, the second charging module 7 is connected to the AC power strip. The second charging module 7 detects the AC voltage and sends a charging interlock signal to the MCU control module 3. The MCU control module 3 receives the charging interlock signal and then activates the second charging mode. The specific process of the second charging mode is described in detail in Example 2 and will not be repeated here.

[0096] To discharge the mains plug, connect it to the second discharge module 8. Upon detecting the mains plug being plugged in, the second discharge module 8 sends a discharge interlock signal to the MCU control module 3. Upon receiving the discharge interlock signal, the MCU control module 3 initiates the second discharge mode. The specific process of the second discharge mode is described in detail in Example 2 and will not be elaborated on here.

[0097] In this way, by providing a first charging module 1, a first discharging module 2, a second charging module 7, a second discharging module 8, an MCU control module 3, a PFC inverter main power module 4, a buck-boost module 5, and a power supply module 6, an integrated charging and inverting system for the electric motorcycle power supply is achieved. The MCU control module 3 regulates the coordinated operation of the first charging module 1, the first discharging module 2, the second charging module 7, the second discharging module 8, the PFC inverter main power module 4, the buck-boost module 5, and the power supply module 6, enabling intelligent control and conversion between charging and discharging modes. This avoids the need for two systems within the power supply, effectively simplifies the internal wiring structure, and facilitates assembly. This also reduces the size of the power supply, making it easier to use and carry.

[0098] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
