"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and drawings of this application are used to distinguish similar objects, rather than to describe a specific order or sequence.

[0024] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be deleted.

[0025] Currently, electric vehicles are primarily charged via charging piles. During charging, the electric vehicle's charger connects to the charging gun of the charging pile. The charging pile then outputs a guidance signal to the charger to wake it up. The charger then completes a handshake with the charger by transitioning through the guidance signal's state, entering the charging state.

[0026] However, the quality of existing charging piles varies, or they are affected by harsh environments, and are prone to unexpected jumps in guidance signals. As a result, when electric vehicles have no charging needs and enter a dormant state, the charger is repeatedly awakened, causing the entire electric vehicle to be repeatedly awakened, resulting in unnecessary power consumption.

[0027] The embodiments of the present application provide a charger wake-up control method and an electric vehicle, which are used to prevent the charger from being repeatedly woken up, and to prevent the electric vehicle from being repeatedly woken up, thereby avoiding unnecessary power consumption.

[0028] Please refer to Figure 1 , Figure 1 This is a schematic block diagram of an electric vehicle provided in an embodiment of the present application. The electric vehicle 100 includes a charger 110 and a charging-related device 120 .

[0029] The charger 110 is used to connect to the charging gun 210 of the charging pile 200 outside the electric vehicle 100, and the charging-related device 120 is connected to the charger 110. It can be understood that the charging-related device 120 includes devices related to charging the electric vehicle 100, such as the power battery. The charger 110 includes a control unit and a power unit. After the charger 110 is connected to the charging gun 210, it can convert the electrical energy input by the charging gun 210 into the charging voltage of the power battery, thereby charging the power battery of the electric vehicle 100.

[0030] In an embodiment of the present application, when the charger 110 is connected to the charging gun 210, the charging pile 200 can transmit a guidance signal to the charger 110 through the charging gun 210, complete the handshake between the charger 110 and the charging pile 200, and monitor the interaction function between the charger 110 and the charging pile 200 through the state change of the guidance signal, wherein the guidance signal includes a CC resistance signal and a CP voltage signal, etc., which are not limited here.

[0031] For example, in some embodiments, when the charging pile 200 transmits the CP voltage signal as a guide signal to the charger 110 through the charging gun 210, the specific handshake process and the charging monitoring process may include: (1) before the charging gun 210 is inserted into the electric vehicle 100 and connected to the charger 110, the CP voltage signal may be a high level of 12V; (2) after the charging gun 210 is inserted into the electric vehicle 100 and connected to the charger 110, the CP voltage signal jumps to a 9V level due to the voltage divider resistor of the charger 110; (3) the charging pile 200 detects the CP voltage signal. When the signal jumps to 9V, the high level of the CP voltage signal is switched to PWM output (PWM, pulse width modulation). (4) After the charger 110 receives the PWM CP voltage signal and confirms charging, it controls the switching of the voltage divider resistor so that the pulse amplitude of the CP voltage signal jumps to 6V. (5) The charging pile 200 detects that the pulse amplitude of the CP voltage signal jumps to 6V and controls the main relay to close and start outputting electric energy. (6) The charging pile 200 detects the pulse amplitude of the CP voltage signal in real time. When it finds that the pulse amplitude jumps to non-6V, it disconnects the main relay and stops outputting electric energy.

[0032] Next, combine Figure 1 Introducing a charger wake-up control method provided by an embodiment of the present application, please refer to Figure 2 , specifically including the following steps:

[0033] Step S21: In response to the charger being awakened by the charger awakening source, the jump count value stored before the charger goes into sleep is obtained.

[0034] In the embodiment of the present application, the charger includes components such as a control unit and a power unit. When the charger is awakened from a dormant state, it first enters an initialization mode. In the initialization mode, only the control unit operates, and the control unit does not send any messages to the outside. In the initialization mode, the control unit receives the charger wake-up source transmitted by the charging gun, and obtains the jump count value stored before entering the dormant state in the previous stage from the register, where the jump count value is the number of jumps of the guidance signal of the current charging pile. For example, when the guidance signal includes a CP voltage signal, the number of jumps of the CP voltage signal is recorded as the jump count value.

[0035] In some embodiments, when the guidance signal received by the charger includes a CC resistance signal and a CP voltage signal, the CC resistance signal can be used to determine whether the current charging pile is consistent with the charging pile in the previous stage. If they are consistent, the jump count value stored before entering the sleep state in the previous stage is obtained, otherwise the jump count value is initialized.

[0036] Step S22: When it is determined that the charger wake-up source is a preset guidance signal and the jump count value is less than a preset threshold, a wake-up message is sent to the charging-related device.

[0037] In an embodiment of the present application, the preset guide signal includes a CC resistance signal and / or a CP voltage signal. The control unit of the charger receives the charger wake-up source transmitted by the charging gun, determines that the charger wake-up source is the CC resistance signal and / or the CP voltage signal, and then compares the jump count value with the preset threshold. Since the guide signal of a normal charging pile will not jump multiple times, that is, when a normal charging pile charges an electric vehicle, the number of jumps of the guide signal has a reasonable preset threshold, and exceeding the preset threshold indicates that the charging pile is abnormal. When it is determined that the jump count value is less than the preset threshold, it means that the charging pile is normal, and the control unit of the charger can send a wake-up message to the charging-related device, so that the entire electric vehicle enters the charging working state.

[0038] Step S23: monitoring the preset pilot signal, and updating the transition count value according to the transition state of the preset pilot signal.

[0039] In an embodiment of the present application, after entering the charging working state, the power unit of the charger receives the electric energy from the charging gun and converts the electric energy into a charging voltage to charge the electric vehicle, while the control unit of the charger continuously receives and monitors the preset guidance signal, such as continuously receiving and monitoring the CP voltage signal, and updates the jump count value according to the jump state of the preset guidance signal, that is, the jump count value is increased by 1 when the preset guidance signal jumps.

[0040] Step S24: When the charger meets the preset sleep condition, the current jump count value is stored and the charger is controlled to enter the sleep state.

[0041] In the embodiment of the present application, the preset sleep conditions include the electric vehicle being fully charged, the electric vehicle's main controller receiving a sleep command, or the aforementioned jump count value being equal to a preset threshold value, etc., which are not limited here. When the charger control unit determines that the preset sleep conditions are met, it stores the current jump count value in a register and then controls the charger to enter a sleep state.

[0042] In the embodiment of the present application, when the charger is awakened by the charger wake-up source and it is determined that the charger wake-up source is a preset guidance signal, it is determined whether the stored jump count value is less than a preset threshold value. When it is less than the preset threshold value, the charger is controlled to enter the awakening state to perform charging, and the jump state of the preset guidance signal is monitored to update the jump count value. Therefore, when the charger wake-up source is the preset guidance signal, it is possible to avoid the charger being repeatedly awakened when the number of abnormal jumps of the preset guidance signal exceeds the preset threshold value, thereby avoiding the electric vehicle being repeatedly awakened to generate unnecessary power consumption.

[0043] In some embodiments, as Figure 3 As shown, after the above step S21, the following steps are further included:

[0044] Step S25: When it is determined that the charger wake-up source is the preset guidance signal and the jump count value is equal to the preset threshold, the charger is controlled to enter the sleep state.

[0045] In an embodiment of the present application, the control unit of the charger receives the charger wake-up source transmitted by the charging gun, determines that the charger wake-up source is the CC resistance signal and / or the CP voltage signal, and then compares the jump count value with the preset threshold. When it is determined that the jump count value is equal to the preset threshold, it indicates that the charging pile has woken up the charger from the sleep state multiple times, and the charging pile is abnormal. The control unit of the charger can control the charger to directly enter the sleep state, thereby avoiding the electric vehicle from waking up and entering the charging working state, avoiding the abnormal charging pile from forcibly charging the electric vehicle, and improving the safety of electric vehicle charging.

[0046] In some embodiments, as Figure 4 As shown, after the above step S21, the following steps are further included:

[0047] Step S26: When it is determined that the charger wake-up source is another compliant wake-up signal, the jump count value is reset to zero, and a wake-up message is sent to the charging-related device.

[0048] In an embodiment of the present application, if the charger receives a wake-up signal other than the preset guidance signal, the control unit of the charger can also determine whether the wake-up signal is compliant. When it is determined to be another compliant wake-up signal, the control unit can reset the jump count value to zero and send a wake-up message to the charging-related device, thereby allowing the entire electric vehicle to enter the charging working state.

[0049] It can be understood that when it is determined that the charger wake-up source is not a preset guidance signal, but other compliant wake-up signals, it means that the current charger is reconnected to other compliant charging piles, or the electric vehicle has new charging needs. The jump count value of the preset guidance signal of the previous charging pile or the previous charging need can be reset to zero, which can avoid the jump count value from affecting the charging process of the new charging pile or the new charging need, thereby improving the user experience.

[0050] Step S27: Receive a new preset guidance signal and proceed to step S23.

[0051] In this embodiment of the present application, for a new charging station or new charging demand, the charger resets the jump count value to zero, then re-receives and monitors the preset guidance signal from the charging station, determines whether the stored jump count value is less than a preset threshold, and enters the wake-up state to perform charging if the value is less than the preset threshold. The charger also monitors the jump state of the preset guidance signal to update the jump count value. When the jump count value equals the preset threshold, the charger enters the sleep state. Step S28: If it is determined that the charger wake-up source is another non-compliant wake-up signal, the charger is controlled to enter the sleep state.

[0052] In an embodiment of the present application, when the control unit of the charger determines that the wake-up source of the charger is a non-compliant wake-up signal, it indicates that the current charger is connected to a non-compliant charging pile, or the current charger is connected to a non-compatible charging pile, and controls the charger not to respond to the non-compliant wake-up signal and enter a sleep state. This can prevent the non-compliant or non-compatible charging pile from damaging the charger during the charging process, thereby improving the charging life of the charger.

[0053] Please refer to Figure 5 , Figure 5 A flowchart of controlling a charger to sleep after a preset sleep condition is met is provided in an embodiment of the present application, specifically including the following steps:

[0054] Step S51: When it is determined that the transition count value reaches a preset threshold, the current transition count value is stored.

[0055] In an embodiment of the present application, during the process of charging an electric vehicle in a charging operating state, when a jump count value is determined to have reached a preset threshold, i.e., when a preset guidance signal of the charging pile is determined to be abnormal, the charger control unit can control the charger to enter a dormant state to ensure that the entire electric vehicle is not awakened by the abnormal preset guidance signal. When the jump count value is determined to have reached the preset threshold, the charger control unit stores the current jump count value. It can be understood that the current jump count value is the preset threshold.

[0056] Step S52: Generate an abnormal awakening flag and send it to the charging-related device to control the charging-related device to enter a dormant state and no longer awaken in response to a preset guidance signal.

[0057] In an embodiment of the present application, the control unit of the charger can also generate an abnormal wake-up flag and send the abnormal wake-up flag to each charging-associated device to ensure that each charging-associated device will not wake up in response to a preset guidance signal after entering a sleep state, thereby avoiding the charging-associated device being repeatedly woken up and reducing its service life.

[0058] Step S53: After determining that the charging-related device enters the sleep state, control the charger to enter the sleep state.

[0059] In the embodiment of the present application, since the current jump count value is the preset threshold, after the control unit writes the current jump count value into the register, when the charger is awakened by the guidance signal again in the next stage, since the jump count value has reached the preset threshold, the charger will no longer send a wake-up message to the charging-associated device, thereby avoiding the electric vehicle from repeatedly waking up the entire vehicle, and thus avoiding unnecessary power consumption.

[0060] Next, combine Figures 1 to 5 Introducing a method for controlling the status of a charger provided by an embodiment of the present application, please refer to Figure 6 , specifically including the following steps:

[0061] Step S61: In response to the charger being awakened by the charger awakening source, the jump count value stored before the charger goes into sleep is obtained.

[0062] Step S62: Determine whether the charger wake-up source is a preset guidance signal. If yes, proceed to step S63; otherwise, proceed to step S611.

[0063] Step S63: Determine whether the jump count value is less than a preset threshold, if yes, proceed to step S64, otherwise proceed to step S610.

[0064] Step S64: monitoring a preset guidance signal.

[0065] Step S65: Determine whether the preset guidance signal jumps, if so, proceed to step S66, otherwise proceed to step S67.

[0066] Step S66: The jump count value is increased by one.

[0067] Step S67: Determine whether the jump count value is greater than or equal to a preset threshold, if yes, proceed to step S68, otherwise return to step S64. Step S68: Send an abnormal wake-up flag to the charging-related device.

[0068] Step S69: Store the current jump count value.

[0069] Step S610: Entering a dormant state.

[0070] Step S611: Determine whether it is another compliant wake-up signal, if yes, proceed to step S612, otherwise proceed to step S610.

[0071] Step S612: the transition count value is cleared.

[0072] Please refer to Figure 7 , Figure 7 This is a schematic block diagram of another electric vehicle provided in an embodiment of the present application. The electric vehicle 700 includes a charger 710 , a charging-related device 720 , and a main controller 730 .

[0073] In the embodiment of the present application, the charger 710 is connected to an external charging plug, and the charging-related device 720 is connected to the charger 710. When the charger 710 is awakened by a charger awakening source, it obtains the jump count value stored before the sleep state. When it determines that the charger awakening source is a preset guidance signal and the jump count value is less than a preset threshold, it sends a wake-up message to the charging-related device 720, monitors the preset guidance signal, updates the jump count value according to the jump state of the preset guidance signal, and stores the current jump count value and enters the sleep state when the preset sleep condition is met.

[0074] The charging-associated device 720 is used to cooperate with the charger 710 to charge the electric vehicle 700 after receiving the wake-up message.

[0075] The main controller 730 is connected to the charger 710 and is used to wake up the charger 710 when it receives a vehicle wake-up signal. It is understood that after the jump count value reaches the preset threshold, the charger 710 cannot be awakened after detecting the jump of the guidance signal, thereby waking up the entire vehicle to enter the charging state. If the user has a new charging demand, the charger 710 can be awakened by the vehicle wake-up signal. Among them, the vehicle wake-up signal can be an APP remote operation signal of the electric vehicle 700, a key unlocking signal, a key proximity signal, a signal generated by opening and closing the door, etc., which are not limited here.

[0076] In some embodiments, the charger 710 is further configured to enter a sleep state when it determines that the charger 710 wake-up source is a preset boot signal and the transition count value is equal to a preset threshold.

[0077] In some embodiments, the charger 710 is also used to reset the jump count value to zero when determining that the charger wake-up source is other compliant wake-up signals, send a wake-up message to the charging-associated device 720, receive a new preset guidance signal, and enter the step of monitoring the preset guidance signal. When determining that the charger wake-up source is other non-compliant wake-up signals, it enters the sleep state.

[0078] In some embodiments, the charger 710 is also used to store the current jump count value when it is determined that the jump count value reaches a preset threshold, generate an abnormal wake-up identifier and send it to the charging-associated device 720, so as to control the charging-associated device 720 to enter a sleep state and no longer wake up in response to a preset guidance signal, and enter a sleep state after determining that the charging-associated device 720 enters a sleep state.

[0079] In the embodiment of the present application, the beneficial effects of the electric vehicle 700 can refer to the beneficial effects of the wake-up control method of the charger 710 in the aforementioned embodiment, which will not be repeated here.
