Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0031] It should be noted that when using a power supply device such as a charging pile to charge an automobile, the CP (Control Pilot, AC charging control pilot) signal represents a signal for charging guidance, and the CC (Charge Confirm, charging confirmation) signal represents a signal for connection confirmation.

[0032] Referring to Figure 1 , an embodiment of the present application provides a wake-up control device 100. The wake-up control device 100 includes a first status detection module 110, an enable control module 120, a wake-up detection module 130, and a main control module 140. The first status detection module 110 is configured to detect the status of the CP signal and generate a first status signal according to the status of the CP signal. The enable control module 120 is connected to the first status detection module 110. The enable control module 120 is configured to receive the CC signal and generate an enable reset signal according to the CC signal and the first status signal. The wake-up detection module 130 is configured to generate a wake-up demand signal according to the CP signal. The main control module 140 is respectively connected to the first status detection module 110, the enable control module 120, and the wake-up detection module 130. The main control module 140 is configured to generate a first wake-up control signal according to the first status signal, the enable reset signal, and the wake-up demand signal.

[0033] Specifically, the wake-up detection module 130 is configured to receive the CP signal and generate a wake-up demand signal for indicating whether a wake-up operation is required according to the CP signal. The first status detection module 110 is configured to receive the CP signal and determine whether the status of the CP signal meets the wake-up requirement, so as to generate a corresponding first status signal. The enable control module 120 is configured to receive the CC signal and the first status signal, and then determine whether there is a wake-up conflict between the CC signal and the CP signal according to the status of the CC signal and the first status signal, and generate a corresponding enable reset signal. The main control module 140 is configured to generate a corresponding first wake-up control signal when the first status signal meets the CP wake-up requirement, the wake-up demand signal indicates that a wake-up operation is required, and the enable reset signal indicates that there is no wake-up conflict between the CC signal and the CP signal, so that the BMS or other in-vehicle charging devices can control the wake-up charging of the automobile according to the first wake-up control signal.

[0034] For example, referring to Table 1, the CP signal includes two states: a DC voltage signal and a PWM signal. Among them, the DC voltage signal includes a +12V signal and a +9V signal, and the PWM signal includes a +9V PWM signal and a +6V PWM signal. According to the wake-up regulations, when the CP signal is a +12V signal or a +9V signal, it indicates that the AC charging of power supply devices such as charging piles is in the connection confirmation and ready stage. At this time, the CP signal is not processed for wake-up, so the first state detection module 110 generates a first state signal with a low level. When the CP signal is a PWM signal, it indicates that the power supply devices such as charging piles are in the reserved charging stage. At this time, whether the CP signal meets the wake-up regulations is judged and controlled by other controllers. When the reserved charging stage indicates that the reserved charging time is in progress, the CP signal is not processed for wake-up, and the first state detection module 110 generates a first state signal with a low level; when the reserved charging stage indicates that the reserved charging time has ended, the first state detection module 110 generates a first state signal with a high level, that is, the CP signal meets the wake-up regulations.

[0035] Table 1:

[0036] CP signal First state signal +12V 0 +9V 0 +9V PWM 1 +6V PWM 1 +9V PWM 1

[0037] Referring to Table 2, the CP signal is a charging guidance signal, that is, whether a wake-up operation needs to be performed can be fed back according to the state of the CP signal. In relevant regulations (such as GB / T 20234-2015), only when the state of the CP signal is a +6V PWM signal, the power supply devices such as charging piles output the corresponding AC voltage. Therefore, when the state of the CP signal is a +6V PWM signal, the wake-up detection module 130 judges that a wake-up operation needs to be performed, and at this time, the wake-up detection module 130 generates a wake-up demand signal with a high level.

[0038] Table 2:

[0039] CP signal Wake-up demand signal +12V 0 +9V 0 +9V PWM 0 +6V PWM 1 +9V PWM 0

[0040] Referring to Table 3, when the CC signal is a high-level signal, it indicates that the CC signal is in the wake-up operation stage. At this time, in order to avoid wake-up conflicts between the CP signal and the CC signal, regardless of whether the CP signal meets the wake-up regulations, that is, regardless of whether the first state signal is a high-level signal or a low-level signal, the enable reset signal generated by the enable control module 120 is a high-level signal to clear the wake-up operation of the CP signal. When the CC signal is a low-level signal, it indicates that the CC signal is not in the wake-up operation stage. At this time, the level of the enable reset signal is controlled by the first state signal, that is, when the first state signal is at a low level, the enable reset signal is at a high level to avoid charging wake-up; when the first state signal is at a high level, the enable reset signal is at a low level so that the main control module 140 can perform charging wake-up according to the CP signal.

[0041] Table 3:

[0042]

[0043]

[0044] Referring to Table 4, when the first status signal conforms to the CP wake-up regulation, the wake-up demand signal indicates that a wake-up operation is required, and the enable reset signal indicates that there is no wake-up conflict between the CC signal and the CP signal, that is, when the first status signal is a high-level signal, the wake-up demand signal is a high-level signal, and the enable reset signal is a low-level signal, the main control module 140 generates a high-level first wake-up control signal to wake up the vehicle for charging operation. In other states, the first wake-up control signal is a low-level signal, that is, charging cannot be woken up through the CP signal in other states.

[0045] Table 4:

[0046]

[0047] The wake-up control device provided by the embodiment of the present application detects the status of the CP signal through the first status detection module, judges whether there is a wake-up conflict between the CC signal and the CP signal through the enable control module, and detects the wake-up demand of the CP signal through the wake-up detection module, so that the main control module can generate a corresponding first wake-up control signal according to the first status signal, the enable reset signal, and the wake-up demand signal, thereby realizing wake-up control according to the CP signal and solving the wake-up conflict problem between the CP signal and the CC signal.

[0048] Hereinafter, the specific components of the first status detection module 110, the enable control module 120, the wake-up detection module 130, and the main control module 140 and their connection relationships will be specifically described. However, it should be understood that the following description is only exemplary, that is, except for the components described below, the components and their connection relationships capable of implementing the above principles should all fall within the protection scope of the embodiment of the present application.

[0049] Referring to Figure 2 , in some embodiments, the first status detection module 110 includes a level conversion unit 111 and a status detection unit 112. The level conversion unit 111 is used to perform a level conversion operation on the CP signal. The status detection unit 112 is connected to the level conversion unit 111 and is used to detect the status of the CP signal after the level conversion operation and generate a first status signal according to the status of the CP signal after the level conversion operation.

[0050] Specifically, the level conversion unit 111 is configured to receive the CP signal and convert the DC voltage CP signal of +12V (or +9V) into a DC voltage signal of 3.3V (or 5V). After the conversion, the PWM signal remains a PWM signal. The state detection unit 112 is configured to detect whether the state of the CP signal after the level conversion operation is a PWM signal. If the CP signal is a DC voltage signal of 3.3V (or 5V), a first state signal with a low level is generated; if the CP signal is a PWM signal, a first state signal with a high level is generated, thereby realizing the state detection of the CP signal. It can be understood that the specific values of the DC voltage CP signal converted into the DC voltage signal can also be adaptively adjusted according to actual needs, and the embodiments of the present application do not make specific limitations.

[0051] Referring to Figure 3 , in some embodiments, the level conversion unit includes a first resistor R1, a second resistor R2, a first voltage-controlled current element Q1, a third resistor R3, a conversion power supply 113, a fourth resistor R4, a second voltage-controlled current element Q2, and a fifth resistor R5. One end of the first resistor R1 is configured to receive the CP signal; one end of the second resistor R2 is connected to the other end of the first resistor R1, and the other end of the second resistor R2 is grounded; the base of the first voltage-controlled current element Q1 is connected to one end of the second resistor R2, and the emitter of the first voltage-controlled current element Q1 is grounded; one end of the third resistor R3 is connected to the collector of the first voltage-controlled current element Q1; the conversion power supply 113 is connected to the other end of the third resistor R3; one end of the fourth resistor R4 is connected to the collector of the first voltage-controlled current element Q1; the base of the second voltage-controlled current element Q2 is connected to the other end of the fourth resistor R4, and the emitter of the second voltage-controlled current element Q2 is connected to the conversion power supply 113; one end of the fifth resistor R5 is connected to the collector of the second voltage-controlled current element Q2, and the other end of the fifth resistor R5 is grounded.

[0052] Specifically, the conversion power supply 113 is configured to provide a converted DC voltage, that is, the conversion power supply 113 can be a 3.3V power supply, a 5V power supply, etc. The first voltage-controlled current element Q1 is an NPN-type triode, and the second voltage-controlled current element Q2 is a PNP-type triode. The CP signal flows through the first resistor R1 to the base of the first voltage-controlled current element Q1, thereby causing the first voltage-controlled current element Q1 to conduct, and then generating a DC voltage signal or a PWM signal formed after the CP signal undergoes a level conversion operation across the fifth resistor R5.

[0053] Referring to Figures 2 to 4, in some embodiments, the status detection unit 112 includes a first capacitor C1, a diode D1, a second capacitor C2, and a sixth resistor R6. One end of the first capacitor C1 is connected to one end of the fifth resistor R5; the anode of the diode D1 is connected to the other end of the first capacitor C1, and the cathode of the diode D1 is respectively connected to the enable control module 120 and the main control module 140; one end of the second capacitor C2 is connected to the cathode of the diode D1, and the other end of the second capacitor C2 is grounded; the sixth resistor R6 is connected in parallel with the second capacitor C2.

[0054] Specifically, the first capacitor C1 is an AC coupling capacitor, and the first capacitor C1, the diode D1, the second capacitor C2, and the sixth resistor R6 constitute a PWM AC power conversion circuit. Therefore, when the CP signal after the level conversion operation is a DC voltage signal, a first status signal with a low level will be generated at both ends of the sixth resistor R6; when the CP signal after the level conversion operation is a PWM signal, a first status signal with a high level will be generated at both ends of the sixth resistor R6, thereby realizing the status detection of the CP signal.

[0055] Refer to Figures 2 to 4 , in some embodiments, the enable control module 120 includes a first NOT gate Q3, a first AND gate Q4, and a second NOT gate Q5. The input end of the first NOT gate Q3 is used to receive the CC signal; the input ends of the first AND gate Q4 are respectively connected to the output ends of the first status detection module 110 and the first NOT gate Q3; the input end of the second NOT gate Q5 is connected to the output end of the first AND gate Q4, and the output end of the second NOT gate Q5 is connected to the main control module 140.

[0056] Specifically, the enable control module 120 realizes the wake-up conflict detection between the CC signal and the CP signal through a logic circuit. The input ends of the first AND gate Q4 are respectively connected to the first NOT gate Q3 and one end of the third resistor R3, that is, the first AND gate Q4 is used to perform an AND operation on the first status signal and the inverted signal of the CC signal. When the first AND gate Q4 generates a high-level signal, the enable reset signal generated by the second NOT gate Q5 is a low-level signal, which indicates that there is no wake-up operation for the CC signal at this time. Therefore, when the CP signal meets the wake-up regulations and the wake-up demand signal indicates that a wake-up operation is required, the main control module 140 can generate a high-level first wake-up control signal to control the BMS or other on-vehicle charging devices to wake up and charge the vehicle according to the CP signal.

[0057] Refer to Figures 2 to 4 , in some embodiments, the wake-up detection module 130 includes a wake-up detection unit 131 and a control unit 132. The wake-up detection unit 131 is used to detect the voltage and / or duty cycle of the CP signal; the control unit 132 is connected to the wake-up detection unit 131 and is used to generate a wake-up demand signal according to the voltage and / or duty cycle of the CP signal.

[0058] Specifically, the wake-up detection unit 131 is configured to detect the maximum voltage when the CP signal is a DC voltage signal, and / or to detect the duty cycle when the CP signal is a PWM signal. The control unit 132 is configured to receive the maximum voltage or the duty cycle, and generate a corresponding wake-up demand signal according to the maximum voltage or the duty cycle. When the wake-up demand signal is a high-level signal, it indicates that a power supply device such as a charging pile can provide an AC voltage, and at this time, the BMS or other in-vehicle charging devices can be woken up for charging.

[0059] Referring to Figures 2 to 4 , in some embodiments, the main control module 140 includes a D flip-flop and a second AND gate Q6. The input terminals of the D flip-flop are respectively connected to the enable control module 120 and the wake-up detection module 130; the input terminals of the second AND gate Q6 are respectively connected to the output terminal of the D flip-flop and the first state detection module 110.

[0060] Specifically, the D terminal of the D flip-flop is connected to the control unit 132 for receiving the wake-up demand signal; the CP terminal of the D flip-flop is connected to the control unit 132 for receiving the clock signal sent by the control unit 132; the RD terminal (active high) of the D flip-flop is connected to the output terminal of the second NOT gate Q5 for receiving the enable reset signal; the Q terminal of the D flip-flop is connected to the input terminal of the second AND gate Q6. Therefore, when the enable reset signal is a high-level signal, regardless of the state of the wake-up demand signal, the output signal of the Q terminal of the D flip-flop is a low-level signal. At this time, regardless of the state of the first state signal, the output signal (i.e., the first wake-up control signal) of the second AND gate Q6 is a low-level signal, thus avoiding the wake-up conflict between the CP signal and the CC signal.

[0061] Referring to Figure 5 , in some embodiments, the wake-up control device 100 further includes a second state detection module 150. The second state detection module 150 is connected to the main control module 140, and the second state detection module 150 is configured to detect the state of the hard wire signal and generate a second state signal according to the state of the hard wire signal.

[0062] Specifically, when the wake-up control device 100 includes the second state detection module 150, the main control module 140 generates a second wake-up control signal according to the second state signal, the first state signal, the enable reset signal, and the wake-up demand signal to avoid the wake-up conflict among the hard wire signal, the CP signal, and the CC signal. In some specific embodiments, the second state detection module 150 includes a level conversion unit, and the output terminal of the level conversion unit is connected to the input terminal of the second AND gate Q6. It can be understood that the level conversion unit of the second state detection module 150 has the same function as the level conversion unit 111 of the first state detection module 110, so the level conversion unit of the second state detection module 150 will not be described in detail in the embodiments of the present application.

[0063] Reference Figure 6 Figure 6 , the embodiment of the present application further provides a wake-up control system, which is applied to an automobile. The wake-up control system includes: a wake-up control device 100 and a battery management system 200 described in any of the above embodiments.
