[0032] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limiting the present application.

[0033] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 1 is an application scenario diagram of a charging device 100 provided in an embodiment of the present application. The application scenario provided in the present application includes a vehicle 2000 and an energy storage system 1000. The energy storage system 1000 includes an energy storage device 200 and a charging device 100. The energy storage device 200 and the charging device 100 are connected.

[0034] Vehicle 2000 includes fuel vehicles, hybrid vehicles and electric vehicles. Fuel vehicles, hybrid vehicles and electric vehicles may all generate redundant power. For example, fuel vehicles and hybrid vehicles are equipped with generators. When the output power of the generator exceeds the driving requirements of vehicle 2000 (such as high-speed cruising, downhill coasting), the excess output power is redundant power. For another example, electric vehicles and hybrid vehicles are equipped with motors. When vehicle 2000 decelerates or brakes, the motor switches to generator mode, recovers kinetic energy and converts it into electrical energy, thereby generating redundant power. Therefore, the power supply module 2001 of vehicle 2000 includes a generator or a motor. The generator includes a generator for fuel vehicles and a generator for hybrid vehicles. The motor includes a motor for electric vehicles or a motor for hybrid vehicles.

[0035] Generators include both intelligent and non-intelligent generators. Intelligent generators are equipped with an electronic control unit that intelligently adjusts the generator's output power based on the vehicle's power requirements. For example, during acceleration, intelligent generators adjust power generation based on engine load, while during idling, the generator reduces load to improve fuel efficiency and reduce unnecessary energy waste. Non-intelligent generators typically rely on traditional mechanical regulation, resulting in a relatively fixed output power and inability to intelligently adjust to the vehicle's power requirements. Their load is primarily determined by engine speed, making them less efficient than intelligent generators.

[0036] Energy storage device 200 is a device capable of storing power. It typically includes rechargeable batteries. These batteries store large amounts of power and, when needed, release the stored energy. Energy storage device 200 may include a battery module and a processor. The battery module stores power, while the processor controls and manages the battery module, as well as other components of the energy storage device 200.

[0037] The charging device 100 is a device that uses the redundant power generated during the driving of the vehicle 2000 to charge the external energy storage device 200. Its core goal is to power other devices by recovering energy that would otherwise be wasted (such as excess engine power, braking energy, deceleration and coasting energy, etc.). The charging device 100 can be installed in the engine compartment, under the seat, or in the trunk of the vehicle 2000, without limitation. One end of the charging device 100 is connected to the power supply module 2001 of the vehicle 2000, and the other end is connected to the energy storage device 200, so as to use the redundant power of the power supply module 2001 of the vehicle 2000 to charge the energy storage device 200.

[0038] Based on the above-mentioned related scenarios, an embodiment of the present application provides a charging device 100, which is described in detail below:

[0039] See also Figure 1 and Figure 2 The charging device 100 provided in an embodiment of the present application is used to connect to a vehicle 2000. When the charging device 100 is connected to the vehicle 2000, the charging device 100 is connected in series with the power supply module 2001 of the vehicle 2000 and in parallel with the starting battery 2002 of the vehicle 2000. The charging device 100 includes a power supply input port A1, a detection port A3, a power supply output port A2, a button 20 and a controller 10. The power supply input port A1 is used to connect to the power supply module 2001 of the vehicle 2000. The detection port A3 is used to connect to the starting module of the vehicle 2000 and to receive a starting signal sent by the starting module, which is used to start the vehicle 2000. The power supply output port A2 is used to connect to the energy storage device 200. The button 20 is connected to the controller 10. The controller 10 is configured to control the charging device 100 to enter the standby mode or the shutdown mode based on the start signal, the voltage of the start battery 2002 , the pressing time of the button 20 and the standby time when the charging device 100 is in the working mode.

[0040] Specifically, the charging device 100 includes an operating mode, a standby mode, and a shutdown mode. When the charging device 100 is in the operating mode, most of the devices inside the charging device 100 are in an operating state. When the charging device 100 is in the standby mode, all devices except the controller 10 and the auxiliary power module 40 stop working, wherein the controller 10 is in a low-power state but retains some functions for quick wake-up or shutdown. When the charging device 100 is in the shutdown mode, all devices inside the charging device 100 stop working.

[0041] The starting module is used to start the vehicle 2000. When starting the vehicle 2000, the starting module of some vehicles 2000 can send a starting signal, where the starting signal is an electrical signal. For example, the starting signal includes an ignition signal (IGN-ON) and / or an accessory power supply signal (ACC). The ignition signal represents power to the core control system and sensors of the vehicle 2000, preparing or maintaining engine operation, and is an essential power level for driving. The accessory power supply signal represents power supply to non-core accessory devices of the vehicle 2000 to meet parking or short-term use needs.

[0042] For example, for vehicle 2000 that requires a car key for ignition, the ignition switch is the starting module. The ignition switch connects the circuit through physical contacts. At this time, the ignition switch can trigger different gears and output signals through a mechanical knob. The gears include ACC and IGN-ON. When the gear is ACC, the ignition switch sends an accessory power supply signal. When the gear is IGN-ON, the ignition switch sends an ignition signal. For vehicle 2000 with keyless start / electronic ignition, the starting module includes a vehicle controller, a body control module (BCM), or an integrated power management unit. When the starting module receives an ignition command from the user, it will send an ignition signal. When the starting module receives a power supply command from the user, it will send an accessory power supply signal.

[0043] Power input port A1 is connected to the power supply module 2001 of the vehicle 2000, and power output port A2 is connected to the energy storage device 200, for example, the battery module of the energy storage device 200. Power from the power supply module 2001 enters the charging device 100 through power input port A1. The charging device 100 adjusts the power from the power supply module 2001 and then transmits the power to the energy storage device 200 through power output port A2, thereby powering the energy storage device 200.

[0044] Detection port A3 can be connected to a startup module of vehicle 2000, for example, via a communication line. When the startup module starts vehicle 2000, it can send a high level signal to detection port A3 via the communication line. This high level signal serves as a startup signal. Alternatively, the startup module can be connected to a bus system of vehicle 2000, with detection port A3 connected to the bus system of vehicle 2000. The startup module can send a startup message to the bus system. This message serves as a startup signal. When detection port A3 receives the startup message via the bus system, it is considered that the startup signal has been received.

[0045] The button 20 is connected to the controller 10 . When the user presses the button 20 for a long time, the button 20 can send a signal to the controller 10 .

[0046] When the charging device 100 is connected to the vehicle 2000, it is connected in series with the vehicle's power supply module 2001 and in parallel with the vehicle's starting battery 2002. Furthermore, the series connection between the vehicle's starting battery 2002 and the power supply module 2001 ensures that the voltage of the starting battery 2002 is the same as the output voltage of the power supply module 2001. Therefore, if the power supply capacity of the power supply module 2001 is insufficient or the voltage of the starting battery 2002 is low, and the charging device 100 continues to operate at a high power, the voltage of the starting battery 2002 may be low. In the event of a low voltage, the starting battery 2002 may not be able to start the vehicle 2000 properly.

[0047] Therefore, when the charging device 100 is in the working mode, the controller 10 can control the charging device 100 to enter the standby mode or the shutdown mode based on the start signal, the voltage of the start battery 2002, the pressing time of the button 20 and the standby time.

[0048] The start signal can be used to reflect whether the vehicle 2000 is turned off. When the vehicle 2000 is turned off, the charging device 100 can be controlled to enter the standby mode or shutdown mode, so that the energy consumption of the charging device 100 can be reduced in time when the vehicle 2000 is turned off and the power supply module 2001 stops working, thereby avoiding excessive consumption of the power of the starting battery 2002.

[0049] The voltage of the starting battery 2002 can directly reflect the power of the starting battery 2002 . Therefore, the controller 10 can control the charging device 100 to enter the standby mode or the shutdown mode according to the voltage of the starting battery 2002 to prevent the power of the starting battery 2002 from being over-consumed.

[0050] The pressing time of the button 20 can reflect the user's usage intention, so the controller 10 can control the charging device 100 to enter the standby mode or the shutdown mode according to the pressing time of the button 20.

[0051] If the standby time is too long, it can be considered that the user is not willing to use the device. At this time, the controller 10 can control the charging device 100 to enter the shutdown mode to reduce the energy consumption of the charging device 100 to 0, thereby avoiding excessive consumption of the power of the starting battery 2002.

[0052] The charging device 100 of the present application is equipped with a button 20 and a detection port A3 capable of receiving a start signal from the starting module of the vehicle 2000. The controller 10 can also detect the voltage of the starting battery 2002. When the charging device 100 is in operating mode, the controller 10 is configured to control the charging device 100 to enter standby mode or shutdown mode based on the start signal, the voltage of the starting battery 2002, the duration of the button 20 being pressed, and the standby time. In other words, the controller 10 can control the charging device 100 to enter standby mode or shutdown mode when appropriate to ensure that the charging device 100 does not consume excessive energy from the starting battery 2002, thereby ensuring that the starting battery 2002 is always able to start the vehicle 2000 normally.

[0053] Optionally, refer to Figure 1 and Figure 2 The controller 10 is configured to determine that the power supply module 2001 is an intelligent generator or motor when the detection port A3 can receive the start signal, and to determine that the power supply module 2001 is a non-intelligent generator when the detection port A3 cannot receive the start signal.

[0054] Specifically, the starting module is used to start the vehicle 2000. The starting module of some vehicles 2000 can send a starting signal to the outside when starting the vehicle 2000, wherein the starting signal refers to an electrical signal. For example, the starting signal includes an ignition signal (IGN-ON) and / or an accessory power supply signal (ACC). The ignition signal represents the power supply to the core control system and sensors of the vehicle 2000, preparing or maintaining the engine operation, and is an essential power level for driving. The accessory power supply signal represents the power supply to the non-core accessory devices of the vehicle 2000 to meet the needs of parking or short-term use.

[0055] For example, for a vehicle 2000 that requires a car key for ignition, the ignition switch is the starting module. The ignition switch connects the circuit through physical contacts. At this time, the ignition switch can trigger different gears through a mechanical knob and output signals. The gears include ACC and IGN-ON. When the gear is ACC, the ignition switch sends an accessory power supply signal. When the gear is IGN-ON, the ignition switch sends an ignition signal. For a vehicle 2000 with keyless start / electronic ignition, the starting module includes a vehicle controller 10, a body control module (BCM), or an integrated power management unit. When the starting module receives an ignition command from the user, it will send an ignition signal. When the starting module receives a power supply command from the user, it will send an accessory power supply signal.

[0056] Detection port A3 can be connected to a startup module of vehicle 2000, for example, via a communication line. When the startup module starts vehicle 2000, it can send a high level signal to detection port A3 via the communication line. This high level signal serves as a startup signal. Alternatively, the startup module can be connected to a bus system of vehicle 2000, with detection port A3 connected to the bus system of vehicle 2000. The startup module can send a startup message to the bus system. This message serves as a startup signal. When detection port A3 receives the startup message via the bus system, it is considered that the startup signal has been received.

[0057] The ACC / IGN-ON signal from a non-intelligent generator is essentially a mechanical signal, while the ACC / IGN-ON signal from a smart generator or motor is an electrical signal. The signal received by detection port A3 is an electrical signal. Therefore, a vehicle 2000 equipped with a non-intelligent generator cannot send a start signal to detection port A3. However, a vehicle 2000 equipped with a smart generator or motor can send a start signal to detection port A3.

[0058] Detection port A3 is communicatively connected to controller 10. Therefore, controller 10 can determine the type of power supply module 2001 by detecting whether port A3 can receive a startup signal. If detection port A3 can receive a startup signal, controller 10 determines that power supply module 2001 is an intelligent generator or motor. If detection port A3 cannot receive a startup signal, controller 10 determines that power supply module 2001 is a non-intelligent generator.

[0059] Furthermore, when determining whether power supply module 2001 is a smart generator or motor, the determination of whether power supply module 2001 is a smart generator or motor can be made based on the different characteristics of the smart generator and motor when installed in vehicle 2000. In certain embodiments, when determining whether power supply module 2001 is a smart generator or motor, the determination of whether power supply module 2001 is a smart generator or motor can also be made based on the message content in the bus system. The message content differs when a smart generator and motor are installed in vehicle 2000. For example, a typical message for a smart generator includes a request frame and a response frame. The request frame: The ECU sends the generator target voltage / current (e.g., CAN ID 0x2F0, data [01 45] indicates an output of 45A). The response frame: The generator feedback status (e.g., CAN ID 0x2F1, data [00 13 88] indicates an output voltage of 13.8V). Typical messages for a motor system include torque commands and energy flow. The torque command: The VCU sends the motor target torque (e.g., CAN ID 0x1A0, data [FF 80] indicates -50% torque recovery). Energy flow: Interaction between the high-voltage battery and the motor (e.g., CAN ID 0x1B0, data [01 0F] indicates a charging power of 15kW). Controller 10 is communicatively connected to the bus system of vehicle 2000. Controller 10 can obtain messages from the bus system and, based on the message content, determine whether power supply module 2001 is a smart generator or a motor.

[0060] In this way, the controller 10 can determine the type of the power supply module 2001 based on the startup signal and the message content, so as to make corresponding control actions according to the type of the power supply module 2001, such as obtaining different thresholds, which is conducive to improving the efficiency of the power supply module 2001.

[0061] Optionally, refer to Figure 1 and Figure 2 When the power supply module 2001 is a smart generator or motor and the charging device 100 is in the working mode, the controller 10 controls the charging device 100 to enter the standby mode if at least one of the following conditions is met:

[0062] The detection port A3 does not receive the start signal, or the voltage of the start battery 2002 of the vehicle 2000 is less than the first preset voltage threshold.

[0063] Specifically, when the charging device 100 is connected to the vehicle 2000, it is connected in series with the power supply module 2001 of the vehicle 2000 and in parallel with the starting battery 2002 of the vehicle 2000. Therefore, when the output power of the power supply module 2001 is low and the output power of the charging device 100 is high, the starting battery 2002 may charge the charging device 100. If the power of the starting battery 2002 is too low, the starting battery 2002 may not be able to start the vehicle 2000 normally.

[0064] The first preset voltage threshold is a safe lower limit warning value for the voltage of the starting battery 2002 when the power supply module 2001 of the vehicle 2000 is a smart generator or a motor. The first preset voltage threshold is used to trigger the standby mode to reduce power consumption, extend operating time, and prevent the charging device 100 from consuming too much power from the starting battery 2002. For example, the first preset voltage threshold is 11.8V / 22.8V. The first preset voltage thresholds for smart generators and motors may be different.

[0065] If detection port A3 does not detect a start signal, it is assumed that power supply module 2001 is no longer supplying power. Controller 10 then controls charging device 100 to enter standby mode. This reduces power consumption and prevents the vehicle's starting battery 2002 from being completely depleted.

[0066] The controller 10 can obtain the voltage of the starting battery 2002. For example, a processor of the vehicle 2000 can obtain the voltage of the starting battery 2002 via a sensor. The processor is in communication with the controller 10 and transmits the obtained voltage of the starting battery 2002 to the controller 10. Alternatively, a corresponding detection circuit can be provided between the controller 10 and the starting battery 2002. When the voltage of the starting battery 2002 is greater than a second preset threshold, the detection circuit can transmit a high level signal to the controller 10. The controller 10 can then determine whether the voltage of the starting battery 2002 is less than the first preset voltage threshold based on the level signal transmitted by the detection circuit.

[0067] When the controller 10 determines that the voltage of the starting battery 2002 of the vehicle 2000 is less than the first preset voltage threshold, it is possible that the power supply module 2001 is not operating, or that the power supply module 2001 has a low output power, resulting in a low voltage in the starting battery 2002. Therefore, the controller 10 controls the charging device 100 to enter standby mode to reduce its power consumption. This ensures that when the power supply module 2001 is not operating, the charging device 100 does not draw much power from the starting battery 2002. When the power supply module 2001 is operating but has a low output power, the charging device 100 does not draw much power from the power supply module 2001. This allows more power from the power supply module 2001 to flow into the starting battery 2002, ensuring that the voltage of the starting battery 2002 can quickly rise above the first preset voltage threshold.

[0068] When any of the above conditions is met, the controller 10 will control the charging device 100 to enter the standby mode.

[0069] In this way, the conditions for entering the standby mode when the power supply module 2001 of the vehicle 2000 is a smart generator or motor can be set to ensure that the charging device 100 can enter the standby mode at the appropriate time, thereby reducing the energy consumption of the charging device 100 and not affecting the normal operation of other devices in the vehicle 2000.

[0070] Optionally, refer to Figure 1 and Figure 2 When the power supply module 2001 is a non-intelligent generator and the charging device 100 is in the working mode, if the voltage of the starting battery 2002 of the vehicle 2000 is less than the second preset voltage threshold, the controller 10 controls the charging device 100 to enter the standby mode.

[0071] Specifically, the second preset voltage threshold is a safety lower limit warning value of the voltage of the starting battery 2002 when the power supply module 2001 of the vehicle 2000 is a non-intelligent generator. The second preset voltage threshold is used to trigger the standby mode to reduce power consumption, extend the usage time, and prevent the charging device 100 from consuming too much power from the starting battery 2002. For example, the second preset voltage threshold is 12.5V or 24V.

[0072] When the voltage of the starting battery 2002 of the vehicle 2000 is less than the second preset voltage threshold, the power supply module 2001 may not be working, or the output power of the power supply module 2001 is relatively small, resulting in a relatively small voltage of the starting battery 2002. Therefore, at this time, the controller 10 controls the charging device 100 to enter the standby mode to reduce the power consumption of the charging device 100, thereby ensuring that the charging device 100 does not obtain too much electric energy from the starting battery 2002 when the power supply module 2001 is not working, and ensuring that the charging device 100 does not obtain too much electric energy from the power supply module 2001 when the power supply module 2001 is working but the output power is relatively small, so that more electric energy of the power supply module 2001 can flow into the starting battery 2002, ensuring that the voltage of the starting battery 2002 can quickly rise to above the second preset voltage threshold.

[0073] In this way, the entry conditions for the standby mode can be set when the power supply module 2001 of the vehicle 2000 is a non-intelligent generator to ensure that the charging device 100 can enter the standby mode at an appropriate time, thereby reducing the energy consumption of the charging device 100 and not affecting the normal operation of other devices of the vehicle 2000.

[0074] Optionally, refer to Figure 1 and Figure 2 When the charging device 100 is in the working mode, if the pressing time of the button 20 exceeds the first preset time, the controller 10 controls the charging device 100 to enter the shutdown mode.

[0075] Specifically, when the power supply module 2001 is a non-intelligent generator, the start-up of the charging device 100 will not be controlled by the start signal of the vehicle 2000. When the charging device 100 is in working mode, the user can shut down the charging device 100 by pressing the button 20.

[0076] The first preset duration is used to determine whether the user wishes to shut down the charging device 100 while the charging device 100 is in the operating mode. If the button 20 is pressed for longer than the first preset duration, for example, 3 seconds, while the charging device 100 is in the operating mode, the controller 10 may determine that the user wishes to shut down the charging device 100 and may control the charging device 100 to enter the shutdown mode.

[0077] In this way, when the power supply module 2001 is a non-intelligent generator, the user can shut down the charging device 100 by pressing the button 20 .

[0078] Optionally, refer to Figure 1 and Figure 2 When the charging device 100 is in the standby mode, the controller 10 controls the charging device 100 to enter the shutdown mode if at least one of the following conditions is met:

[0079] In the standby state, the pressing time of the button 20 exceeds the second preset time, the duration of the standby mode exceeds the third preset time, or the voltage of the starting battery 2002 of the vehicle 2000 is less than the third preset voltage threshold, and the third preset voltage threshold is less than the first preset voltage threshold.

[0080] The second preset time length is the shortest pressing time length of the button 20 when it can be determined that the user really wants to shut down the device, for example, 3 seconds.

[0081] The third preset time period is the shortest time period for determining that the user will not charge the energy storage device 200 in a short period of time, for example, 24 hours.

[0082] The third preset voltage threshold is the absolute protection lower limit value of the voltage of the starting battery 2002, which is the minimum voltage when the starting battery 2002 can start the vehicle 2000, for example, 11.5V or 22.5V, wherein the third preset voltage threshold is smaller than the preset voltage threshold corresponding to the entry condition of the standby mode, that is, smaller than the above-mentioned first preset voltage threshold and second preset voltage threshold.

[0083] It should be noted that the power supply module 2001 is not limited and can be a motor, an intelligent generator or a non-intelligent generator, but the thresholds corresponding to the motor, the intelligent generator or the non-intelligent generator may be different.

[0084] Specifically, the controller 10 can obtain the pressing time of the button 20. In the standby state, if the pressing time of the button 20 exceeds the second preset time, it can be considered that the user shuts down the device by pressing the button 20. At this time, the controller 10 can control the charging device 100 to enter the shutdown mode.

[0085] The controller 10 may record the duration of the standby mode. If the duration of the standby mode exceeds a third preset time, it may be considered that the user will not charge the energy storage device 200 in a short time. In this case, the controller 10 may control the charging apparatus 100 to enter the shutdown mode.

[0086] When the voltage of the starting battery 2002 of the vehicle 2000 is less than the third predetermined voltage threshold, it can be considered that the starting battery 2002 is unable to normally start the vehicle 2000. At this time, the controller 10 can control the charging device 100 to enter the shutdown mode to completely eliminate the possibility of the charging device 100 consuming the starting battery 2002.

[0087] When any of the above conditions is met, the controller 10 will control the charging device 100 to enter the shutdown mode.

[0088] In this way, by setting the conditions for entering the shutdown mode, it can be ensured that the charging device 100 can enter the shutdown mode at an appropriate time, thereby ensuring that the charging device 100 can be shut down in time, preventing the charging device 100 from being idle for a long time, and preventing the charging device 100 from running out of power in the starting battery 2002.

[0089] Optionally, refer to Figure 1 and Figure 2 The charging device 100 further includes a voltage conversion circuit 30, which is located on a line between the power supply input port A1 and the power supply output port A2. The voltage conversion circuit 30 is used to adjust the output voltage and output current of the power supply output port A2. The controller 10 is configured to adjust operating parameters of the voltage conversion circuit 30 based on the output power of the power supply module 2001, the output voltage of the power supply module 2001, and a fourth preset voltage threshold, so that the voltage of the starting battery 2002 is greater than the fourth preset voltage threshold.

[0090] Specifically, when the output power of the power supply module 2001 is low and the output power of the charging device 100 is high, the starting battery 2002 may charge the charging device 100. Once the power of the starting battery 2002 is too low, the starting battery 2002 may not be able to start the vehicle 2000 normally.

[0091] The fourth preset voltage threshold is a safe lower limit warning value for the voltage of starting battery 2002. The fourth preset voltage threshold is used to trigger standby mode to reduce power consumption, extend operating time, and prevent charging device 100 from consuming too much energy from starting battery 2002. Due to different operating modes, the redundant power of the smart generator, non-smart generator, and motor may vary, and their output voltages may also vary. For example, the output voltage of the smart generator may be relatively low, while the output voltage of the non-smart generator may be relatively high. Therefore, in certain embodiments, to improve the efficiency of power supply module 2001, the fourth preset voltage thresholds corresponding to the smart generator, non-smart generator, and motor may be different.

[0092] Different models of the same generator have different output voltages. For example, some smart generators have an output voltage of 12V, while others have an output voltage of 24V. Therefore, the corresponding fourth preset voltage threshold can also be determined based on the specific performance of the generator. For example, the fourth preset voltage threshold for a smart generator is 11.8V (for a 12V output voltage smart generator) or 22.8V (for a 24V output voltage smart generator), while the fourth preset voltage threshold for a non-smart generator is 12.5V or 24V. The specific value needs to be determined based on the performance of the generator.

[0093] The voltage conversion circuit 30, also known as the buck-boost module, has the core function of efficiently converting the unstable electric energy output by the vehicle 2000 generator or hybrid system into stable electric energy suitable for charging the energy storage device 200 (such as a power battery, auxiliary battery, etc.) by dynamically adjusting the voltage and current. The voltage conversion circuit 30 is connected to the power supply output port A2. The voltage conversion circuit 30 can dynamically adjust the PWM duty cycle through dual closed-loop control of the voltage loop and the current loop to adjust the output voltage and output current of the voltage conversion circuit 30, thereby adjusting the output voltage and output current of the power supply output port A2. The operating parameters of the voltage conversion circuit 30 refer to parameters that can affect the output voltage and output current of the voltage conversion circuit 30, such as the target voltage of the voltage loop and the target current of the current loop.

[0094] For example, when the voltage of the generator, that is, the voltage of the power input port A1, is lower than the requirement of the energy storage device 200, the circuit conversion circuit can increase the output voltage so that the output voltage of the power output port A2 matches the requirement of the energy storage device 200. For example, if the voltage of the power input port A1 is 12V and the requirement of the energy storage device 200 is 48V, then the voltage conversion circuit 30 can adjust the voltage of the power output port A2 to 48V. In particular, the output power of the generator matches the output power of the power output port A2. Therefore, when the generator operates at a certain power, the output power of the power output port A2 is fixed. Therefore, when the output power is fixed, when the output voltage of the power output port A2 is higher than the output voltage of the generator, the output current of the power output port A2 is smaller. According to the relationship that heat and current are proportional, it can be known that the energy consumption of the charging device 100 in the process of supplying power to the energy storage device 200 is smaller.

[0095] For another example, when the voltage of the generator, that is, the voltage at the power input port A1, is higher than the requirement of the energy storage device 200, the voltage conversion circuit 30 may reduce the output voltage so that the output voltage at the power output port A2 matches the requirement of the energy storage device 200. For example, if the voltage at the power input port A1 is 28V and the requirement of the energy storage device 200 is 24V, the voltage conversion circuit 30 may adjust the voltage at the power output port A2 to 24V.

[0096] The controller 10 is configured to adjust the operating parameters of the voltage conversion circuit 30 according to the output power of the power supply module 2001 and the fourth preset voltage threshold, so that the voltage of the starting battery 2002 is greater than the fourth preset voltage threshold.

[0097] The controller 10 can constantly monitor the output voltage of the power supply module 2001. The output voltage of the power supply module 2001 is the output voltage of the power supply module 2001. The input voltage of the power supply input port A1 is the output voltage of the power supply module 2001. The controller 10 can obtain the input voltage of the power supply input port A1 by, for example, providing a voltage sensor at the power supply input port A1 or at the output port of the power supply module 2001 to determine the input voltage of the power supply input port A1.

[0098] The controller 10 can determine the redundant power of the power supply module 2001 based on the output power of the power supply module 2001. Simultaneously, the controller 10 can also detect the output voltage of the power supply module 2001 to determine the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold. If the difference is large, the redundant power is preferentially utilized as much as possible. That is, while the charging requirements of the energy storage device 200 are met and the output power of the power output port A2 is less than or equal to the redundant power, the output power of the power output port A2 is increased as much as possible to increase the charging power of the energy storage device 200. If the difference is small, the output power of the voltage conversion circuit 30 is preferentially reduced to reduce the energy consumption of the charging device 100, ensuring that more power from the power supply module 2001 can be delivered to the starting battery 2002, and that power from the starting battery 2002 is not delivered to the charging device 100. This ensures that the voltage of the starting battery 2002 does not decrease further and remains above the fourth preset voltage threshold. Based on the above considerations, the controller 10 processes the output power of the power supply module 2001, the output voltage of the power supply module 2001 and the fourth preset voltage threshold, and can obtain the target output voltage and target output current of the voltage conversion circuit 30, and adjust the parameters of the voltage conversion circuit 30 according to the target output voltage and target output current, for example, adjust the target values ​​of the voltage loop and the current loop according to the target output voltage and the target output current, and adjust the PWM duty cycle accordingly to adjust the output voltage and output current of the power supply output port A2.

[0099] In this way, the controller 10 can determine the redundant power of the power supply module 2001 based on the output power of the power supply module 2001, and at the same time constantly detect the output voltage of the power supply module 2001 and the fourth preset voltage threshold, so as to adjust the working parameters of the voltage conversion circuit 30 in combination with the redundant power of the power supply module 2001 and the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold, so that after the voltage conversion circuit 30 adjusts the output voltage and output current of the power supply output port A2, the voltage of the starting battery 2002 can always be greater than the fourth preset voltage threshold, and the electric energy of the starting battery 2002 will not be too low, thereby ensuring that the starting battery 2002 can always start the vehicle 2000 normally.

[0100] Optionally, refer to Figure 1 and Figure 2 The controller 10 is configured to identify the type of the power supply module 2001 to obtain a fourth preset voltage threshold according to the type of the power supply module 2001; determine a target output voltage and a target output current of the power supply output port A2 corresponding to the power supply module 2001 according to the charging demand of the energy storage device 200, the output power of the power supply module 2001, the output voltage of the power supply module 2001, and the fourth preset voltage threshold corresponding to the power supply module 2001, and determine the operating parameters of the voltage conversion circuit 30 according to the target output voltage and the target output current.

[0101] The charging requirements of the energy storage device 200 include the requirements for charging power, charging voltage, or charging current when the energy storage device 200 can be normally charged. For example, the charging requirements of the energy storage device 200 include the maximum allowable charging current, the maximum allowable charging voltage, or the maximum allowable charging power.

[0102] Specifically, the controller 10 can identify the type of power supply module 2001 according to the above method and obtain the fourth preset voltage threshold corresponding to the power supply module 2001. The controller 10 can then determine the redundant power of the power supply module 2001 based on the output power of the power supply module 2001. For example, the redundant power of the power supply module 2001 can be determined based on the difference between the output power of the power supply module 2001 and the total power consumption of the electrical devices of the vehicle 2000. Simultaneously, the output voltage of the power supply module 2001 is obtained to determine the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold.

[0103] Next, the target output power of power output port A2 is determined based on the difference between the redundant power and the output voltage of power supply module 2001 and the fourth preset voltage threshold. For example, when the difference is large, it is sufficient to ensure that the target output power is less than or equal to the redundant power and that the target output power meets the charging requirements of energy storage device 200. When the difference is small, while ensuring that the target output power is less than or equal to the redundant power, the target output power is reduced to reduce the energy consumption of charging device 100, allowing more electrical energy from the power supply module to flow to starting battery 2002, thereby preventing the voltage of starting battery 2002 from dropping below the fourth preset voltage threshold.

[0104] One of the target current and target voltage can be determined based on the charging demand of the energy storage device 200, and then the other of the target current and target voltage can be determined in combination with the target output power. For example, when the redundant power of the power supply module 2001 is large, the target current can be determined based on the maximum allowable charging current to increase the charging rate. The target voltage can be obtained by combining the target output power and the target current. Alternatively, when the redundant power of the power supply module 2001 is large, the target voltage can be determined based on the maximum allowable charging voltage to increase the charging rate. The target current can be obtained by combining the target output power and the target voltage. Finally, the controller 10 can adjust the operating parameters of the voltage conversion module based on the target current and target voltage.

[0105] In this way, the controller 10 can ensure that the output voltage and output current of the power output port A2 can meet the charging requirements of the energy storage device 200. It can also ensure that the output power of the charging device 100 is adjusted in real time based on the real-time power of the power supply module 2001, so that the charging device 100 does not consume excessive power from the power supply module 2001, thereby ensuring the normal operation of other electrical devices in the vehicle 2000. In addition, during the adjustment process, the controller 10 will also detect the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold in real time. In order to promptly detect and execute corresponding operations when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is too small, thereby ensuring that the voltage of the starting battery 2002 is greater than the fourth preset voltage threshold and that the starting battery 2002 can always operate normally.

[0106] Optionally, refer to Figure 1 and Figure 2 The controller 10 is configured to determine the redundant power of the power supply module 2001 according to the output power of the power supply module 2001 when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is greater than the preset difference threshold, so as to determine the target output power of the power supply output port A2 according to the redundant power and the charging requirement of the energy storage device 200, and to determine the target output voltage and target output current of the power supply output port A2 according to the target output power and the charging requirement of the energy storage device 200.

[0107] The preset difference threshold is the minimum difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold when the possibility that the voltage of the starting battery 2002 will fall below the fourth preset voltage threshold in a short period of time is low.

[0108] Specifically, when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is greater than the preset difference threshold, the controller 10 may deem that the output capacity of the power supply module 2001 is relatively strong, and the voltage of the starting battery 2002 is unlikely to fall below the fourth preset voltage threshold in a short period of time, and there is no need to adjust the output voltage and output current of the power supply output port A2 according to the voltage of the starting battery 2002.

[0109] The controller 10 can determine the target output power of the power output port A2 based on the redundant power. The target output power can be less than or equal to the redundant power. For example, the maximum allowable charging power of the energy storage device 200 can be obtained. When the redundant power is less than or equal to the maximum allowable charging power, the target output power is determined to be the redundant power. When the redundant power is greater than the maximum allowable charging power, the target output power is determined to be the maximum allowable charging power.

[0110] Then, one of the target current and target voltage can be determined based on the charging requirements of the energy storage device 200, and the other of the target current and target voltage can be determined in combination with the target output power. If the energy storage device 200 currently requires a charging current, the target current is determined based on the charging current, and the target voltage is then determined based on the target current and the target output power. If the energy storage device 200 currently requires a charging voltage, the target voltage is determined based on the charging voltage, and the target current is then determined based on the target voltage and the target output power.

[0111] In this way, when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is greater than the preset difference threshold, the controller 10 can determine the target current and target voltage of the power output port A2 based on the redundant power of the power supply module and the charging requirements of the energy storage device 200, so as to ensure that the charging device 100 does not consume too much electrical energy from the power supply module, other electrical equipment of the vehicle 2000 can operate normally, and the energy storage device 200 can also be charged normally.

[0112] Optionally, refer to Figure 1 and Figure 2 The controller 10 is configured to determine the redundant power of the power supply module 2001 according to the output power of the power supply module 2001 when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is less than the preset difference threshold, and determine the target output power according to the current output power of the power supply output port A2, the target output power being less than the current output power of the power supply output port A2, and the target output power being less than the redundant power; and determine the target output voltage and target output current of the power supply output port A2 according to the target output power and the charging demand of the energy storage device 200.

[0113] Specifically, when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is less than the preset difference threshold, the controller 10 may believe that there is a high possibility that the voltage of the starting battery 2002 will fall below the fourth preset voltage threshold in a short period of time, and the output voltage and output current of the power supply output port A2 need to be adjusted according to the voltage of the starting battery 2002.

[0114] At this time, the target output power can be determined based on the current output power of power supply output port A2. The target output power is determined when the target output power is less than the current output power of power supply output port A2. For example, the target output power is determined based on the difference between the current output power and a preset step size, or based on the product of the current output power and a preset ratio less than 1. At the same time, the redundant power of power supply module 2001 is determined based on the output power of power supply module 2001 to ensure that the target output power is less than the redundant power. If the target output power is greater than the redundant power, the target output power is adjusted to the redundant power. If the target output power is less than the redundant power, no further adjustment of the target output power is required.

[0115] Next, one of the target current and the target voltage may be determined according to the charging demand of the energy storage device 200 , and then the other of the target current and the target voltage may be determined in combination with the target output power.

[0116] In this way, when the difference between the output voltage of the power supply module 2001 and the fourth preset voltage threshold is less than the preset difference threshold, the controller 10 reduces the output power of the charging device 100 to reduce the energy consumption of the charging device 100 and the energy storage device 200, ensuring that more electric energy from the power supply module is delivered to the starting battery 2002, and the starting battery 2002 will not charge the charging device 100, thereby ensuring that the voltage of the starting battery 2002 will not drop further.

[0117] Optionally, refer to Figure 1 and Figure 2 The charging device 100 further includes an auxiliary power module 40 , which is configured to supply power to the controller 10 .

[0118] Specifically, the charging device 100 includes an auxiliary power module 40, which is mainly used to provide stable power supply for low-power components such as the control circuit, protection circuit, and communication module inside the module, ensuring that the charging device 100 can work reliably when the vehicle 2000 is started, turned off, or in standby mode.

[0119] The user can issue a start command to the charging device 100, for example, by long-pressing the button 20 of the charging device 100 to trigger the auxiliary power module 40 to operate. The auxiliary power module 40 then supplies power to the controller 10 to start the controller 10. The controller 10 can then power on the system to control the voltage conversion circuit 30 to output power at any time to charge the energy storage device 200.

[0120] In this way, the charging device 100 may be equipped with the auxiliary power module 40 , which can stably supply power to each module of the charging device 100 , so as to ensure the normal operation of the charging device 100 .

[0121] Optionally, refer to Figure 1 and Figure 2 The controller 10 is configured to start the voltage conversion circuit 30 when the output voltage of the power supply module 2001 is greater than a fifth preset voltage threshold.

[0122] Specifically, the power supply module 2001 is primarily used to supply power to various electrical devices in the vehicle 2000. The fifth preset voltage threshold is the minimum voltage required for the power output of the power supply module 2001 to meet the needs of the various electrical devices in the vehicle 2000, for example, 12.5V or 25V. In certain embodiments, the fifth preset voltage thresholds for the smart generator, the non-smart generator, and the motor are different. Due to different operating modes, the redundant power of the smart generator, the non-smart generator, and the motor may vary, and the output voltage may also vary. For example, the output voltage of the smart generator is relatively low, while the output voltage of the non-smart generator is relatively high. Therefore, in certain embodiments, to improve the efficiency of the power supply module 2001, the fifth preset voltage thresholds for the smart generator, the non-smart generator, and the motor may be different. Different models of the same generator also have different output voltages. For example, some smart generators have an output voltage of 12V, while others have an output voltage of 24V. Therefore, the corresponding fifth preset voltage threshold can also be determined based on the specific performance of the generator. For example, the fifth preset voltage threshold corresponding to the smart generator is 12.5V or 25V, and the fifth preset voltage threshold corresponding to the non-intelligent generator is 13.5V or 26V. The specific value needs to be determined in combination with the performance of the generator.

[0123] The input voltage of the power input port A1 is the output voltage of the power module 2001. The controller 10 can obtain the input voltage of the power input port A1, for example, by setting a voltage sensor at the power input port A1 or at the output port of the power module 2001 to determine the input voltage of the power input port A1.

[0124] After the charging device 100 is powered on, it enters standby mode, during which the voltage conversion circuit 30 has not yet begun operating. When the charging device 100 is in standby mode and the input voltage at power input port A1 is less than the fifth preset voltage threshold, the controller 10 may determine that the output power of the power supply module 2001 is insufficient to meet the needs of the various electrical devices in the vehicle 2000. Therefore, the voltage conversion circuit 30 will not be awakened, and the charging device 100 will remain in standby mode. If the input voltage at power input port A1 is greater than the fifth preset voltage threshold, the controller 10 may determine that the output power of the power supply module 2001 is sufficient to meet the needs of the various electrical devices in the vehicle 2000 and that there is redundant output power. Therefore, the voltage conversion circuit 30 will be awakened to charge the energy storage device 200 using the voltage conversion circuit 30, and the charging device 100 will enter operating mode.

[0125] In this way, by determining the fifth preset voltage threshold, the controller 10 can ensure that the energy storage device 200 is supplied with power without affecting the power consumption of various electrical devices of the vehicle 2000, thereby ensuring the normal operation of the vehicle 2000.

[0126] Although the embodiments of the present application have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and intent of the present application, and that the scope of the present application is defined by the claims and their equivalents.
