Description

Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to an activation system for an energy storage device. Background Technology

[0002] With the rapid development of the energy storage industry, portable energy storage devices are widely used in various industries and infrastructures. To verify the current state of the battery in a portable energy storage device, when the device is in hibernation or shutdown, the control module in the device is usually turned on at fixed intervals to collect information such as the current temperature and voltage to understand the current state of the device.

[0003] Portable energy storage devices typically incorporate a real-time clock (RTC) chip to time fixed intervals during sleep or shutdown. When the fixed time is reached, the RTC chip provides an enable level to the peripheral circuitry within the portable energy storage device, activating the control system. To reduce the power consumption of the control system, it automatically goes into sleep or shuts down after a short period of activation (e.g., 2 seconds).

[0004] However, when the RTC chip finishes timing and activates the control system, if the energy storage device simultaneously receives a charging activation signal or a discharging activation signal, the control system will be unable to identify which activation function it is. This may lead to abnormal system operation or problems that are inconsistent with the current activation function. Therefore, how to provide an energy storage device that can accurately identify the activation function to control the energy storage system to be in the corresponding functional state is a technical problem that urgently needs to be solved.

[0010] Optionally, the activation system for the energy storage device may also include: The power supply module includes a power supply control terminal and a power supply output terminal; the power supply output terminal is electrically connected to the power supply input terminal of the main control module; the power supply module is used to provide a power supply signal to the power supply output terminal according to the power supply control signal of the power supply control terminal; the discharge control signal terminal, the charging control signal terminal and the timing output terminal are all electrically connected to the power supply control terminal.

The first locking module is electrically connected to a discharge control signal terminal, a charging control signal terminal, and a timing activation terminal. When the discharge control signal terminal receives a discharge enable signal, or the charging control signal terminal receives a charging enable signal, the first locking module locks the signal at the timing activation terminal as a timing not-ended signal (or a timing not-enabled signal). This ensures the main control module can only recognize the signals from the discharge control signal terminal and the charging control signal terminal, allowing the main control module to operate reliably for extended periods under the influence of either the discharge or charging enable signal. When neither the discharge control signal terminal nor the charging control signal terminal receives a discharge enable signal, the locking function of the first locking module fails, and the timing end signal output by the RTC module is transmitted to the main control module, thus enabling the timing activation function.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0019] Figure 1 This is a schematic diagram of the structure of an activation system for an energy storage device provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the activation system of the energy storage device includes an RTC module 10, a main control module 20, and a first locking module 30. The RTC module 10 includes a timing output terminal INT; when the timing ends, the RTC module 10 provides a timing end signal to the timing output terminal INT. The main control module 20 includes a discharge activation terminal IO3, a charging activation terminal IO2, and a timing activation terminal IO1; the discharge activation terminal IO3 is electrically connected to the discharge control signal terminal F1, the charging activation terminal IO2 is electrically connected to the charging control signal terminal CH1, and the timing activation terminal IO1 is electrically connected to the timing output terminal INT; the main control module 20 starts working according to the activation signals of the discharge activation terminal IO3, the charging activation terminal IO2, and the timing activation terminal IO1. The first locking module 30 includes a first input terminal, a second input terminal, and a first output terminal; the first input terminal is electrically connected to the discharge control signal terminal F1, the second input terminal is electrically connected to the charging control signal terminal CH1, and the first output terminal is electrically connected to the timing activation terminal IO1.

[0020] Among them, RTC module 10 includes timing devices such as RTC chip, main control module 20 includes processors such as microcontroller or single-chip microcomputer, and first locking module 30 includes devices such as switching transistor. These can be set according to actual needs, and no specific limitation is made here.

[0021] Specifically, the RTC module 10 is set with a fixed timing duration. When the energy storage device is powered off (the main control module 20 is also in sleep or powered off state), the RTC module 10 starts timing. When the set timing duration is reached, the RTC module 10 provides a timing end signal to the timing output terminal INT. The timing end signal can be a high-level signal or a low-level signal. The timing end signal is transmitted to the main control module 20 through the timing activation terminal IO1. Based on the timing end signal, the main control module 20 starts working to acquire signals such as the current temperature and current voltage of the energy storage device in a short time. The functional module for acquiring the status signals of the energy storage device is not shown in the figure. After the signal acquisition is completed, the main control module 20 will automatically enter sleep or power-off state. The charging control signal terminal CH1 is used to receive the charging enable signal from the energy storage device. When the power supply port of the external power supply device is electrically connected to the energy storage device, the charging control signal terminal CH1 can receive the charging enable signal. When the charging enable signal is transmitted to the charging activation terminal IO2 through the charging control signal terminal CH1, the main control module 20 starts working according to the charging enable signal to ensure that the energy storage device can be charged normally. Correspondingly, the discharging control signal terminal F1 is used to receive the discharging enable signal from the energy storage device. When the discharging control signal terminal F1 receives the discharging enable signal, when the discharging enable signal is transmitted to the discharging activation terminal IO3 through the discharging control signal terminal F1, the main control module 20 starts working according to the discharging enable signal to ensure that the energy storage device can be discharged normally. Normally, the charging enable signal and the discharging enable signal will not exist at the same time. However, if the charging enable signal and the timing end signal are transmitted to the main control module 20 at the same time, or if the discharging enable signal and the timing end signal are transmitted to the main control module 20 at the same time, the main control module 20 may not be able to identify which activation signal activated the control operation, resulting in problems such as abnormal identification by the main control module 20.

[0022] Therefore, by setting up a first locking module 30 electrically connected to the discharge control signal terminal F1, the charging control signal terminal CH1, and the timing activation terminal IO1 respectively, when the discharge control signal terminal F1 receives a discharge enable signal, or the charging control signal terminal CH1 receives a charging enable signal, the first locking module 30 can lock the signal of the timing activation terminal IO1 as a timing not-ended signal (or a timing not-enabled signal) according to the discharge enable signal or the charging enable signal. This ensures that the main control module 20 can only recognize the signals of the discharge control signal terminal F1 and the charging control signal terminal CH1, so that the main control module 20 is in a reliable start-up working state for a long time under the action of the discharge enable signal or the charging enable signal. When the discharge control signal terminal F1 does not receive a discharge enable signal, and the charging control signal terminal CH1 does not receive a charging enable signal, the locking function of the first locking module 30 fails, and the timing end signal output by the RTC module 10 can be transmitted to the main control module 20 to realize the timing activation function.

[0023] The technical solution of this invention, through setting an activation system for an energy storage device, includes an RTC module, a main control module, and a first locking module. The first locking module is electrically connected to a discharge control signal terminal, a charging control signal terminal, and a timing activation terminal, respectively. When the discharge control signal terminal receives a discharge enable signal, or the charging control signal terminal receives a charging enable signal, the first locking module can lock the signal at the timing activation terminal as a timing not-ended signal (or a timing not-enabled signal) based on the discharge enable signal or the charging enable signal. This ensures that the main control module can only recognize the signals from the discharge control signal terminal and the charging control signal terminal, allowing the main control module to maintain a reliable, long-term startup state under the influence of the discharge enable signal or the charging enable signal. When the discharge control signal terminal does not receive a discharge enable signal, or the charging control signal terminal does not receive a charging enable signal, the locking function of the first locking module fails, and the timing end signal output by the RTC module can be transmitted to the main control module, realizing the timing activation function. Thus, by setting a first locking module, when the charging control signal terminal receives a charging enable signal or the discharging control signal terminal receives a discharging enable signal, the first locking module can control the priority of the charging enable signal or the discharging enable signal to be higher than the priority of the timing end signal, thereby achieving charging and discharging priority and improving the reliability of the activation function of the energy storage device's activation system.

[0024] Optional, Figure 2 This is a schematic diagram of the activation system of another energy storage device provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the first locking module 30 includes a first transistor Q1, a first diode D1, and a second diode D2; the anode of the first diode D1 is electrically connected to the first input terminal, the anode of the second diode D2 is electrically connected to the second input terminal, and the cathodes of the first diode D1 and the second diode D2 are both electrically connected to the control terminal of the first transistor Q1; the first electrode of the first transistor Q1 is electrically connected to the first signal terminal V1, and the second electrode of the first transistor Q1 is electrically connected to the timing activation terminal IO1.

[0025] In this embodiment, the first transistor Q1 can be an N-type transistor, and the voltage signal of the first signal terminal V1 can be set according to actual needs. For example, in one optional embodiment, the voltage signal of the first signal terminal V1 is a ground signal; in another optional embodiment, the voltage signal of the first signal terminal V1 is a fixed high-level signal of 3.3V. No specific limitation is made here. The voltage signal of the first signal terminal V1 is consistent with the timing not-ended signal (or timing not-enabled signal) of the RTC module 10. For example, when the timing end signal of the RTC module 10 is a high-level signal and the timing not-ended signal is a low-level signal, the voltage signal of the first signal terminal V1 is also a low-level signal; correspondingly, when the timing end signal of the RTC module 10 is a low-level signal and the timing not-ended signal is a high-level signal, the voltage signal of the first signal terminal V1 is also a high-level signal.

[0026] Specifically, both the discharge enable signal received by the discharge control signal terminal F1 and the charge enable signal received by the charge control signal terminal CH1 are high-level signals, both capable of controlling the first transistor Q1 to be in the conducting state. When the discharge control signal terminal F1 receives the discharge enable signal, the discharge enable signal is transmitted to the control electrode of the first transistor Q1 through the first diode D1, and the first transistor Q1 is in the conducting state. The first transistor Q1 can transmit the voltage signal of the first signal terminal V1 to the timing activation terminal IO1. After receiving the voltage signal of the first signal V1, the main control module 20 does not activate the timing activation function. Correspondingly, when the charge control signal terminal CH1 receives the charge enable signal, the charge enable signal is transmitted to the control electrode of the first transistor Q1 through the second diode D2, and the first transistor Q1 is in the conducting state. The first transistor Q1 can transmit the voltage signal of the first signal terminal V1 to the timing activation terminal IO1. After receiving the voltage signal of the first signal V1, the main control module 20 does not activate the timing activation function. Thus, by setting the first locking module 30 to include a first transistor Q1, a first diode D1, and a second diode D2, when a charging enable signal or a discharging enable signal is input, the first locking module 30 can lock the signal received by the timing activation terminal IO1 as a timing not-ended signal (or a timing not-enabled signal), thereby realizing that the charging activation function and the discharging activation function take precedence over the timing activation function.

[0027] Furthermore, by setting a first diode D1 and a second diode D2, when the discharge enable signal of the discharge control signal terminal F1 is transmitted to the control electrode of the first transistor Q1 through the first diode D1, the presence of the second diode D2 prevents the discharge enable signal of the control electrode of the first transistor Q1 from being transmitted to the charging signal terminal CH1 through the second diode D2. This avoids crosstalk between the signals of the discharge control signal terminal F1 and the charging control signal terminal CH1, and improves the signal accuracy of the charging control signal terminal CH1 and the discharge control terminal F1.

[0028] Optional, Figure 3 A schematic diagram of the structure of an activation system for another energy storage device provided in an embodiment of the present invention is shown below. Figure 3 As shown, the activation system of the energy storage device also includes a second locking module 40, which includes a third input terminal, a fourth input terminal, and a third output terminal; the third input terminal is electrically connected to the first output terminal, and the third output terminal is electrically connected to the timing activation terminal IO1; the fourth input terminal is electrically connected to the first power supply terminal VCC1; the second locking module 40 is used to control the transmission of the first power supply signal of the first power supply terminal VCC1 to the timing activation terminal IO1 according to the output signal of the first output terminal.

[0029] The second locking module 40 may include devices such as switching transistors, and can be configured according to actual needs; no specific limitations are made here. The first power supply signal of the first power supply terminal VCC1 can be a high-level signal, such as 3.3V.

[0030] Specifically, by setting up a second locking module 40 that is electrically connected to the first locking module 30, the first power supply VCC1, and the timing activation terminal IO1 respectively, after the first locking module 30 outputs a first locking signal under the control of the charging enable signal at the charging control signal terminal CH1 or the discharging enable signal at the discharging control signal terminal F1, the first locking signal can control the second locking module 40 to transmit the first power supply signal at the first power supply terminal VCC1 to the timing activation terminal. The first power supply signal is consistent with the timing not-ended signal (or timing non-enabled signal) of the RTC module 10, so that the signal of the timing activation terminal IO1 is locked as the timing not-ended signal (or timing non-enabled signal) through the first locking module 30 and the second locking module 40, so that the main control module 20 can only recognize the charging enable signal and the discharging enable signal, and the recognition is accurate.

[0031] Optional, Figure 4 A schematic diagram of the structure of an activation system for another energy storage device provided in an embodiment of the present invention is shown below. Figure 4 As shown, the second locking module 40 includes a second transistor Q2, a first resistor R1, and a second resistor R2; the first terminal of the second transistor Q2 is electrically connected to the first power supply terminal VCC1, the second terminal of the second transistor Q2 is electrically connected to one end of the first resistor R1, the other end of the first resistor R1 is electrically connected to the timing activation terminal IO1, the control terminal of the second transistor Q2 is electrically connected to one end of the second resistor R2, and the other end of the second resistor R2 is electrically connected to the first output terminal.

[0032] In this circuit, the voltage signal at the first signal terminal V1 is a ground signal, the voltage signal at the first power supply terminal VCC1 is a high-level signal, for example, 3.3V, and the second transistor Q2 is a P-type transistor. The first resistor R1 acts as a voltage divider, and the second resistor R2 acts as a current limiter.

[0033] Specifically, when the voltage signal of the first signal terminal V1 is a ground signal and the timing end signal of the RTC module 10 is a low-level signal, if the second locking module 40 is not set, when the RTC module 10 outputs the timing end signal and the charging control signal terminal CH1 receives the charging enable signal or the discharging control signal terminal F1 receives the discharging enable signal, the first locking module 40 will transmit the ground signal of the first signal terminal V1 to the timing activation terminal IO1 under the action of the charging enable signal or the discharging enable signal. The main control module 20 will simultaneously recognize the timing end signal of the timing activation terminal IO1 and the charging enable signal of the charging activation terminal IO2 or the discharging enable signal of the discharging activation terminal IO3, causing the main control module 20 to recognize abnormally. Therefore, when the voltage signal at the first signal terminal V1 is a ground signal and the timing end signal of the RTC module 10 is a low-level signal, by setting the second locking module 40, when the RTC module 10 outputs the timing end signal and the charging control signal terminal CH1 receives the charging enable signal or the discharging control signal terminal F1 receives the discharging enable signal, the first locking module 40 will, under the action of the charging enable signal or the discharging enable signal, transmit the ground signal of the first signal terminal V1 through the first resistor R1 to the control electrode of the second transistor Q2. The second transistor Q2 is in the conducting state, and the second transistor Q2 can transmit the first power supply signal of the first power supply terminal VCC1 through the second resistor R2 to the timing activation terminal IO1. The first power supply signal cannot activate the timing activation function, so the main control module 20 can only recognize the charging enable signal of the charging activation terminal IO2 or the discharging enable signal of the discharging activation terminal IO3, thereby improving the recognition reliability and activation accuracy of the main control module 20.

[0034] Optional, Figure 5 This is a schematic diagram of the structure of an activation system for an energy storage device provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the activation system of the energy storage device also includes a power supply module 60, which includes a power supply control terminal EN and a power supply output terminal EO. The power supply output terminal EO is electrically connected to the power supply input terminal of the main control module 20. The power supply module 60 is used to provide a power supply signal to the power supply output terminal EO according to the power supply control signal of the power supply control terminal EN. The discharge control signal terminal F1, the charging control signal terminal CH1, and the timing output terminal INT are all electrically connected to the power supply control terminal EN.

[0035] The power supply module 60 includes auxiliary power supply circuit chips, etc., which can be configured according to actual needs, and no specific limitation is made here. The power supply output terminal EO can output the power supply voltage required for the main control module 20 to operate. The power supply voltage required for the main control module 20 to operate can be configured according to actual needs, for example, it can be 3.3V, and no specific limitation is made here.

[0036] Specifically, when the power supply control signal received by the power supply control terminal EN of the power supply module 60 is a power supply enable signal, the power supply module 60 can provide the required power supply voltage to the main control module 20 through the power supply output terminal EO; when the power supply control signal received by the power supply control terminal EN of the power supply module 60 is a power supply disable signal, the power supply module 60 stops providing the required power supply voltage to the main control module 20. By setting the discharge control signal terminal F1, the charging control signal terminal CH1, and the timing output terminal INT to be electrically connected to the power supply control terminal EN, when one of the three is a power supply enable signal, the power supply module 60 can be controlled to provide a power supply signal to the main control module 20, so that the main control module 20 can realize the corresponding activation function under the action of the power supply signal. Among them, the power supply enable signal is a high-level signal. Thus, by setting up the power supply module 60, the power supply module 60 will only provide a power supply signal to the main control module 20 when one of the discharge control signal terminal F1, the charging control signal terminal CH1, and the timing output terminal INT provides a power supply enable signal to the power supply module 60. This allows control over the duration of the power supply signal provided by the power supply module 60 to the main control module 20, eliminating the need to provide a power supply signal to the main control module 20 at all times and saving power consumption.

[0037] Optional, Figure 6 This is a schematic diagram of the activation system of another energy storage device provided in an embodiment of the present invention, as shown below. Figure 6 As shown, the activation system of the energy storage device also includes a third diode D3, a fourth diode D4, and a fifth diode D5; the anode of the third diode D3 is electrically connected to the discharge control signal terminal F1, and the cathode of the third diode D3 is electrically connected to the power supply control terminal EN; the anode of the fourth diode D4 is electrically connected to the charging control signal terminal CH1, and the cathode of the fourth diode D4 is electrically connected to the power supply control terminal EN; the anode of the fifth diode D5 is electrically connected to the timing output terminal INT, and the cathode of the fifth diode D5 is electrically connected to the power supply control terminal EN.

[0038] Specifically, by setting a third diode D3 between the power supply control terminal EN and the discharge control signal terminal F1, a fourth diode D4 between the power supply control terminal EN and the charging control signal terminal CH1, and a fifth diode D5 between the power supply control terminal EN and the timing output terminal INT, interference between the discharge control signal terminal F1, the charging control signal terminal CH1, and the timing output terminal INT is avoided, thereby improving the signal stability of the discharge control signal terminal F1, the charging control signal terminal CH1, and the timing output terminal INT.

[0039] Optional, Figure 7 A schematic diagram of the structure of an activation system for another energy storage device provided in an embodiment of the present invention is shown below. Figure 7As shown, the activation system of the energy storage device also includes a first control module 50. The first control module 50 includes a first control terminal, a first terminal, and a second terminal. The first control terminal is electrically connected to the timing output terminal INT, the first terminal is electrically connected to the second power supply terminal VCC2, and the second terminal is electrically connected to the power supply control terminal EN. The first control module 50 is used to control the transmission of the second power supply signal of the second power supply terminal VCC2 to the power supply control terminal EN according to the timing output signal of the timing output terminal INT.

[0040] The timing output terminal INT and one of the second terminals are electrically connected to the timing activation terminal IO1. The second power supply signal of the second power supply terminal VCC2 can be a high-level signal, such as a voltage signal of 3.3V, or other signals; no specific limitation is made here.

[0041] Specifically, when the timing end signal output by the RTC module 10 is a low-level signal, this low-level signal cannot control the power supply module 60 to provide a power supply signal to the main control module 20. By setting up a first control module 50 that is electrically connected to the timing output terminal INT, the second power supply terminal VCC2, and the power supply control terminal EN respectively, when the timing end signal output by the RTC module 10 is a low-level signal, this low-level signal can control the first control module 50 to transmit the voltage signal of the second power supply terminal VCC2 to the power supply control terminal EN. This allows the power supply module 60 to respond promptly when the main control module 20 implements the timing activation function, providing a power supply signal to the main control module 20. This prevents the main control module 20 from failing to start working upon receiving the timing end signal, thus improving the operational reliability of the main control module 20.

[0042] One of the timing output terminal INT and the second terminal is electrically connected to the timing activation terminal IO1. When the timing end signal output by the RTC module 10 is a low-level signal and the enable level of the timing activation terminal IO1 is high, the second terminal of the first control module 50 is electrically connected to the timing activation terminal IO1. When the timing end signal output by the RTC module 10 is a low-level signal and the enable level of the timing activation terminal IO1 is low, the timing output terminal INT is electrically connected to the timing activation terminal IO1. This ensures that when the timing end signal is output by the timing output terminal INT, the timing activation terminal IO1 can receive the enable level corresponding to the timing end signal, thus realizing the timing activation function.

[0043] Optional, Figure 8 A schematic diagram of the structure of an activation system for another energy storage device provided in an embodiment of the present invention is shown below. Figure 8As shown, the first control module 50 includes a third transistor Q3, a third resistor R3, and a fourth resistor R4; the first terminal of the third transistor Q3 and one end of the third resistor R3 are both electrically connected to the second power supply terminal VCC2, the control terminal of the third transistor Q3 is electrically connected to one end of the fourth resistor R4, the other ends of the third resistor R3 and the other ends of the fourth resistor R4 are both electrically connected to the timing output terminal INT, and the second terminal of the third transistor Q3 is electrically connected to the power supply control terminal EN.

[0044] In this design, the third transistor Q3 can be a P-type transistor, and the fourth resistor R4 serves as a current limiter. R3 acts as a pull-up resistor for Q3, ensuring that when Q3 is off, it transmits the second power supply signal from the second power supply terminal VCC2 to the timing output terminal INT, preventing INT from being in an uncertain floating state. The specific values ​​of R3 and R4 can be set according to actual needs and are not specifically limited here.

[0045] Specifically, when the timing end signal output by the timing output terminal INT of the RTC module 10 is a low-level signal, this low-level signal controls the third transistor Q3 to be in the conducting state through the fourth resistor R4. The third transistor Q3 transmits the second power supply signal of the second power supply terminal VCC2 to the power supply control terminal EN, so that when the timing function is activated, the main control module 20 can obtain the power supply signal provided by the power supply module 60 to realize the timing activation function. Correspondingly, when the timing not-ended signal (or timing non-enable signal) output by the timing output terminal INT of the RTC module 10 is a high-level signal, this high-level signal controls the third transistor Q3 to be in the off state through the fourth resistor R4. The third transistor Q3 cannot transmit the second power supply signal of the second power supply terminal VCC2 to the power supply control terminal EN, so that when the timing function is not activated, the main control module 20 cannot obtain the power supply signal provided by the power supply module 60, thereby achieving the effect of saving energy consumption.

[0046] Optional, Figure 9 This is a schematic diagram of the structure of an activation system for an energy storage device provided in an embodiment of the present invention, as shown below. Figure 9 As shown, when the second terminal is electrically connected to the timing activation terminal IO1, the first control module 50 also includes a fifth resistor R5, which is electrically connected between the timing activation terminal IO1 and the second terminal of the third transistor Q3.

[0047] The resistance value of the fifth resistor R5 can be set according to actual needs, and no specific limitation is made here.

[0048] Specifically, by setting a fifth resistor R5 between the timing activation terminal IO1 and the second terminal of the third transistor Q3, the current signal entering the timing activation terminal IO1 from the third transistor Q3 is limited, so as to avoid the current signal entering the main control module 20 being too large and affecting the safety of the main control module 20.

[0049] It should be noted that, Figure 10 This is a schematic diagram of the activation system of another energy storage device provided in an embodiment of the present invention, as shown below. Figure 10 As shown, when the timing output terminal INT is electrically connected to the timing activation terminal IO1, a sixth resistor can be connected in series between the two to limit the current signal entering the timing activation terminal IO1, so as to avoid the current signal entering the main control module 20 being too large and affecting the safety of the main control module 20.

[0050] Optional, Figure 11 A schematic diagram of the structure of an activation system for another energy storage device provided in an embodiment of the present invention is shown below. Figure 11 As shown, the activation system of the energy storage device also includes a voltage divider module 70; the voltage divider module 70 is electrically connected between the charging control signal terminal CH1 and the charging activation terminal IO2.

[0051] The voltage divider module 70 includes components such as resistors, which can be configured according to actual needs.

[0052] Specifically, if the charging enable signal provided by the charging control signal terminal CH1 is greater than the upper limit of the operating voltage of the main control module 20, a voltage divider module 70 is set to convert the charging enable signal provided by the charging control signal terminal CH1 into a voltage signal that the main control module 20 can recognize. This improves the reliability of the main control module 20 in realizing the charging activation function, while preventing the voltage signal transmitted to the main control module 20 from exceeding the upper limit of the voltage that the main control module 20 can withstand, thus improving the operational safety of the main control module 20.

[0053] Understandably, the power supply signal for the RTC module 10 can be provided by a low-dropout linear regulator. The low-dropout linear regulator converts the energy storage voltage in the energy storage device into a fixed voltage required for the RTC module 10 to operate continuously. Furthermore, a communication transmission line can be provided between the main control module 20 and the RTC module 10, allowing the main control module 20 to transmit timing duration and reset signals to the RTC module 10 via the communication transmission line.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, combinations, and substitutions can be made without departing from the scope of protection of the present invention.
