Description

Technical Field

[0001] This application relates to the field of power control technology for rapid power replenishment, and more particularly to control methods, power supplies and electronic devices for rapid power replenishment. Background Technology

[0002] With the increasing demand for high energy density and rapid charging capabilities from portable electronic devices, power tools, electric vehicles, and energy storage systems, traditional single-battery module power systems are gradually revealing significant bottlenecks in charging efficiency. In existing technologies, most rechargeable power supplies typically have only one charging port, charging the entire battery module uniformly through this port. When using high-power charging, limitations such as the internal chemical reaction rate, thermal management capabilities, and the consistency of individual cells often make it difficult to further increase charging speed. If multiple charging ports are used, the energy storage units within the battery module are typically fixedly connected in series and parallel, making it impossible to independently control the charging and discharging paths of each part. This results in the current input from multiple ports still needing to converge into the same circuit, not only failing to achieve true parallel charging but also potentially causing safety risks or reduced charging efficiency due to voltage / current mismatch.

[0003] Furthermore, in scenarios such as emergency power supply or outdoor operations, users often need to replenish power quickly. However, due to structural limitations, existing power systems cannot simultaneously connect to multiple external charging sources (such as multiple fast charging adapters, vehicle power supplies, and AC power) for coordinated charging, thus severely restricting their rapid charging capabilities. Therefore, there is an urgent need for a new power structure that can dynamically adjust the electrical connections of internal energy storage modules when multiple charging ports are simultaneously connected to external power sources. This allows each energy storage module to be decoupled from each other and receive independent charging, thereby fully utilizing multiple input power sources, significantly improving the overall charging speed, and meeting users' actual needs for efficient and rapid charging.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides embodiments of a control method. It should be noted that although the logical order is shown in the flowchart, under certain data conditions, the steps shown or described may be performed in a different order than that shown here.

[0021] Before introducing the control method of the embodiments of this application, the application scenarios of the control method will be explained first. The control method of this application can be applied to smart terminals such as smartphones, tablets and computers, and can also be applied to servers. This application does not make any special limitations here, as long as it can carry and implement the control method of this application.

[0022] The following explanation uses the application of control methods on the server side, but it should be understood that the control methods are not limited to the server side.

[0023] The following is combined Figures 1 to 4 This application describes the control method, the power supply capable of rapid power replenishment, and the electronic equipment.

[0024] According to the embodiments of the first aspect of this application, such as Figure 2As shown, the power supply capable of rapid power replenishment includes a battery module 1, which includes a first energy storage module 11, a second energy storage module 12, and a third switch 13. The third switch 13 is electrically connected between the first energy storage module 11 and the second energy storage module 12. The power supply capable of rapid power replenishment has a first charging port 2 and a second charging port 3.

[0025] It is understood that the battery module 1 is equipped with a first charging port 2 and a second charging port 3, both of which can be connected to a charging power source. When it is confirmed that both the first charging port 2 and the second charging port 3 are connected to a charging power source, the third switch 13 is controlled to disconnect the first energy storage module 11 and the second energy storage module 12, making them independent. Then, the first charging port 2 is electrically connected to the first energy storage module 11 to charge it using the charging power source at the first charging port 2. The second charging port 3 is electrically connected to the second energy storage module 12 to charge it using the charging power source at the second charging port 3. This achieves dual-power charging of the fast-charging power supply, improving its charging speed and shortening its charging time, thus meeting the user's need for rapid charging.

[0026] The power supply capable of rapid power replenishment also includes a first switch 4 and a first DC / DC 5. The first charging port 2, the first DC / DC 5, and the charging port of the first energy storage module 11 are sequentially electrically connected. The main charging port of the battery module 1 is electrically connected to the first switch 4. The first switch 4 can switch between a first state and a second state. In the first state, the first switch 4 connects the first charging port 2 and the main charging port of the battery module 1. In the second state, the first switch 4 connects the first charging port 2 and the first DC / DC 5.

[0027] The power supply capable of rapid power replenishment also includes a second switch 6 and a second DC / DC converter 7. The second charging port 3, the second DC / DC converter 7, and the charging port of the second energy storage module 12 are sequentially electrically connected. The main charging port of the battery module 1 is electrically connected to the second switch 6. The second switch 6 can switch between a third state and a fourth state. In the third state, the second switch 6 connects the second charging port 3 and the main charging port of the battery module 1. In the fourth state, the second switch 6 connects the second charging port 3 and the second DC / DC converter 7.

[0028] According to an embodiment of the second aspect of this application, such as Figure 1 and Figure 2As shown, a control method is applied to a power supply capable of rapid power replenishment. The power supply includes a battery module 1, which comprises a first energy storage module 11, a second energy storage module 12, and a third switch 13. The third switch 13 is electrically connected between the first energy storage module 11 and the second energy storage module 12. The power supply has a first charging port 2 and a second charging port 3. The control method includes: Step 101: Confirm that both the first charging port 2 and the second charging port 3 are connected to a charging power source; Step 102: Control the third switch 13 to disconnect the connection between the first energy storage module 11 and the second energy storage module 12; Step 103: Control the first charging port 2 to be electrically connected to the first energy storage module 11 to charge the first energy storage module 11; Step 104: Control the second charging port 3 to be electrically connected to the second energy storage module 12 to charge the second energy storage module 12.

[0029] According to the control method of this application, the battery module 1 is provided with a first charging port 2 and a second charging port 3, both of which can be connected to a charging power source. When it is determined that both the first charging port 2 and the second charging port 3 are connected to a charging power source, the third switch 13 is controlled to disconnect the first energy storage module 11 and the second energy storage module 12, making the first energy storage module 11 and the second energy storage module 12 independent of each other. Then, the first charging port 2 is controlled to be electrically connected to the first energy storage module 11, so that the charging power source at the first charging port 2 can be used to charge the first energy storage module 11. The second charging port 3 is controlled to be electrically connected to the second energy storage module 12, so that the charging power source at the second charging port 3 can be used to charge the second energy storage module 12. This realizes the use of dual power sources to charge the fast-charging power source, improving the charging speed of the fast-charging power source and shortening the charging time of the fast-charging power source, which can meet the user's fast charging needs.

[0030] Understandably, in related technologies, battery module 1 has only one charging port, thus requiring only one charging power source for charging. However, in this application, battery module 1 has two charging ports. When only one charging port is connected to a charging power source, the third switch 13 connects the first energy storage module 11 and the second energy storage module 12, allowing the charging power source to directly charge the entire fast-charging power supply. When both the first charging port 2 and the second charging port 3 are connected to a charging power source, the third switch 13 disconnects the first energy storage module 11 and the second energy storage module 12, making them independent. This allows one charging power source to charge the first energy storage module 11 while the other charges the second energy storage module 12, achieving dual-power charging and improving charging speed.

[0031] In some examples, the third switch 13 is a controllable relay or MOSFET switch, controlled by the control module, used to connect or disconnect the electrical connection between the first energy storage module 11 and the second energy storage module 12.

[0032] In some examples, when executing a control method, First, the dual charging port status is detected. The control module monitors the connection status of the first charging port 2 and the second charging port 3 in real time. When it is detected that both charging ports are connected to a valid charging power source (for example, the first port is connected to a solar input voltage ≥18V, and the second port is connected to a mains adapter voltage 220V), the dual-port charging mode is triggered.

[0033] Then, the energy storage module isolation control is implemented. The control module sends a disconnect command to the third switch 13, completely disconnecting the electrical connection between the first energy storage module 11 and the second energy storage module 12, forming two independent charging circuits. This avoids mutual charging or energy loss between the two energy storage modules due to voltage differences, and also eliminates the risk of mutual interference between power sources during parallel charging.

[0034] Then, the charging circuit is dynamically allocated. The first charging port 2 is connected to the first energy storage module 11: the control module closes the access switch of the first charging port 2 (such as MOSFET Q1), and directly connects the input power (such as solar energy) of the first charging port 2 to the positive and negative terminals of the first energy storage module 11. The first energy storage module 11 is charged through the charging management circuit (such as MPPT controller). The second charging port 3 is connected to the second energy storage module 12: the access switch of the second charging port 3 is closed synchronously (such as MOSFET Q2), and the input power (such as AC adapter) of the second charging port 3 is connected to the positive and negative terminals of the second energy storage module 12. The second energy storage module 12 is charged through constant voltage / constant current (CV / CC) mode.

[0035] Therefore, this application specifically achieves at least the following technical effects: Dual-port power superposition: By disconnecting the third switch 13, the energy storage module is divided into independent units, so that the two charging ports can supply power to different energy storage modules at the same time. The total input power is the sum of the power of the two ports (for example, 300W solar input + 500W AC input = 800W total input), breaking through the single-port power limitation and significantly shortening the charging time.

[0036] Power compatibility guarantee: When the two charging ports are connected to power sources with different characteristics (such as unstable solar power and stable AC power), the voltage conflict between the power sources is avoided due to the isolation of the energy storage module, and each power source adapts to the battery requirements through an independent charging management circuit.

[0037] The following explanation of this application will be based on a real-world scenario: Assuming the total capacity of the fast-charging power supply is 2000Wh and the maximum input power per port is 500W, traditional single-port charging takes 4 hours to fully charge. However, with this method, if both ports are used simultaneously (300W solar power + 500W AC power), the total power increases to 800W, the charging time is shortened to about 2.5 hours, and the efficiency is improved by about 37.5%.

[0038] In some embodiments, the power supply capable of rapid power replenishment further includes a first switch 4 and a first DC / DC 5. The first charging port 2, the first DC / DC 5, and the charging port of the first energy storage module 11 are sequentially electrically connected. The main charging port of the battery module 1 is electrically connected to the first switch 4. The first switch 4 can switch between a first state and a second state. In the first state, the first switch 4 connects the first charging port 2 and the main charging port of the battery module 1. In the second state, the first switch 4 connects the first charging port 2 and the first DC / DC 5.

[0039] It is understandable that the first switch 4 is a dual-channel switching switch (such as a relay or MOSFET combination), controlled by the control module, and has two states: First state (direct connection mode): the first charging port 2 is directly connected to the main charging port of the battery module 1, and the input power directly charges the entire battery module 1; Second state (DC / DC mode): the first charging port 2 is connected to the input terminal of the first DC / DC5 module, and the output terminal of the first DC / DC5 module is connected to the independent charging port of the first energy storage module 11. The first DC / DC5 module is a buck-boost DC / DC converter used to adjust the input voltage to match the energy storage module's requirements (such as boosting the unstable low voltage of the solar panel to the charging voltage of the energy storage module).

[0040] Understandably, when only the first charging port 2 is connected to a high-voltage power source such as an adapter, the direct connection mode bypasses the DC / DC module, reducing energy conversion losses (e.g., DC / DC efficiency is approximately 95%, direct connection efficiency is approximately 100%), thus achieving fast charging. When the first charging port 2 and the second charging port 3 are connected to the power source simultaneously, the first switch 4 switches the input of the first charging port 2 to charge the first energy storage module 11, while the second charging port 3 independently charges the second energy storage module 12. This achieves the superposition of the two power sources, with the input power of the two ports independently distributed to different energy storage modules. The total charging power is the sum of the power of the two ports (e.g., 300W solar power + 500W AC power = 800W), which shortens the charging time by approximately 37.5% compared to a single-port charging.

[0041] In some examples, when the first charging port 2 is connected to a low-voltage power source (such as solar power), the input power is boosted by a DC / DC module to ensure efficient utilization of the input power.

[0042] In some examples, when a charging power source is connected to a single charging port (e.g., only the first charging port 2 is connected to a power source): The control module detected that the second charging port 3 was not connected to a valid power source, while the first charging port 2 had a valid input (e.g., voltage ≥ 5V).

[0043] The control module determines the input power type: If the input voltage matches the voltage of the main charging port of battery module 1 (e.g., the AC adapter outputs 54.6V corresponding to the 48V energy storage module), then the first switch 4 is controlled to switch to the first state (direct connection mode), and the input power directly charges the entire battery module 1 through the main charging port.

[0044] If the input voltage is mismatched (e.g., solar input is 18V), the first switch 4 is switched to the second state (DC / DC mode), and the input power is adjusted by the first DC / DC 5 module to charge the first energy storage module 11.

[0045] When both the first charging port 2 and the second charging port 3 are connected to a charging power source: The control module detects that both ports are connected to a valid power source and triggers the dual-port charging mode.

[0046] The first switch 4 switches to the second state (DC / DC mode): the first charging port 2 charges the first energy storage module 11 through the first DC / DC 5 module.

[0047] The second charging port 3 is directly connected to the second energy storage module 12: The second charging port 3 charges the second energy storage module 12 directly or via the second DC / DC 7 module.

[0048] Specifically, the step of controlling the first charging port 2 to be electrically connected to the first energy storage module 11 to charge the first energy storage module 11 includes: Control the first switch 4 to disconnect the first charging port 2 and the main charging port of the battery module 1, and control the first switch 4 to connect the first charging port 2 and the first DC / DC 5; The first DC / DC5 is controlled to perform voltage conversion on the power supply at the first charging port 2 in order to charge the first energy storage module 11.

[0049] It is understandable that the first DC / DC5 can perform voltage conversion on the power supply at the first charging port 2 to obtain a voltage that matches the first energy storage module 11, so as to charge the first energy storage module 11.

[0050] In one embodiment of this application, the control method further includes: When the first charging port 2 is connected to a charging power source, and the second charging port 3 is not connected to a charging power source. Control the third switch 13 to connect the first energy storage module 11 and the second energy storage module 12; Control the first switch 4 to connect the first charging port 2 and the main charging port of the battery module 1, and control the first switch 4 to disconnect the first charging port 2 and the first DC / DC 5.

[0051] Understandably, the connection status of the first charging port 2 and the second charging port 3 is monitored in real time. When it is detected that the first charging port 2 is connected to a valid power source (e.g., voltage ≥ 5V) and the second charging port 3 is not connected to a power source, a single-port charging mode is triggered. A closing command is sent to the third switch 13 (S3) to connect the first energy storage module 11 and the second energy storage module 12 together, forming a unified battery module 1. The control module controls the first switch 4 to switch to the first state (direct connection mode), that is: disconnecting the connection between the first charging port 2 and the first DC / DC5 module; and directly connecting the first charging port 2 to the main charging port of the battery module 1.

[0052] In other words, when only the first charging port 2 is connected to a high-voltage power source such as an adapter, the two energy storage modules are connected together by closing the third switch 13, and the first switch 4 is directly connected to the main charging port, so the input power directly charges the entire battery module 1. By bypassing the energy conversion loss of the DC / DC module (efficiency ≈ 100%), the charging speed is maximized, the equivalent capacity of the energy storage module is increased, and a higher input current can be accepted (e.g., a single energy storage module is limited to 10A, and the current is limited to 20A after parallel connection).

[0053] In one embodiment of this application, the power supply capable of rapid power replenishment further includes a second switch 6 and a second DC / DC 7. The second charging port 3, the second DC / DC 7, and the charging port of the second energy storage module 12 are sequentially electrically connected. The main charging port of the battery module 1 is electrically connected to the second switch 6. The second switch 6 can switch between a third state and a fourth state. In the third state, the second switch 6 connects the second charging port 3 and the main charging port of the battery module 1. In the fourth state, the second switch 6 connects the second charging port 3 and the second DC / DC 7.

[0054] Understandably, the second switch 6 is a dual-channel switching switch (such as a relay or MOSFET combination), controlled by the control module, and has two states: The third state (direct connection mode) directly connects the second charging port 3 to the main charging port of the battery module 1, allowing the input power to directly charge the entire battery module 1; the fourth state (DC / DC mode) connects the second charging port 3 to the input terminal of the second DC / DC7 module, and the output terminal of the second DC / DC7 module is connected to the independent charging port of the second energy storage module 12. The second DC / DC7 module is a buck-boost DC / DC converter used to adjust the input voltage to match the energy storage module's requirements (e.g., boosting the unstable low voltage of the solar panel to the charging voltage of the energy storage module).

[0055] Understandably, when only the second charging port 3 is connected to a high-voltage power source such as an adapter, the direct connection mode bypasses the DC / DC module, reducing energy conversion losses (e.g., DC / DC efficiency is approximately 95%, direct connection efficiency is approximately 100%), thus achieving fast charging. When the first charging port 2 and the second charging port 3 are connected to a power source simultaneously, the second switch 6 switches the input of the second charging port 3 to charge the second energy storage module 12, while the first charging port 2 independently charges the first energy storage module 11. This achieves the superposition of the power from the two power sources, with the input power from the two ports independently distributed to different energy storage modules. The total charging power is the sum of the power from both ports (e.g., 300W solar power + 500W AC power = 800W), shortening the charging time by approximately 37.5% compared to a single-port charging.

[0056] In some examples, when the second charging port 3 is connected to a low-voltage power source (such as solar power), the input power is boosted by a DC / DC module to ensure efficient utilization of the input power.

[0057] In some examples, when a power source is connected to a single charging port (e.g., only the second charging port 3 is connected to a power source): The control module detected that the first charging port 2 was not connected to a valid power source, and the second charging port 3 had a valid input (e.g., voltage ≥ 5V).

[0058] The control module determines the input power type: If the input voltage matches the voltage of the main charging port of battery module 1 (e.g., the AC adapter outputs 54.6V corresponding to the 48V energy storage module), then the second switch 6 is switched to the third state (direct connection mode), and the input power directly charges the entire battery module 1 through the main charging port.

[0059] If the input voltage is mismatched (e.g., solar input is 18V), the second switch 6 is switched to the fourth state (DC / DC mode), and the input power is adjusted by the second DC / DC 7 module to charge the second energy storage module 12.

[0060] When both the first charging port 2 and the second charging port 3 are connected to a charging power source: The control module detects that both ports are connected to a valid power source and triggers the dual-port charging mode.

[0061] The second switch 6 switches to the fourth state (DC / DC mode): the second charging port 3 charges the second energy storage module 12 through the first DC / DC 5 module.

[0062] The second charging port 3 is directly connected to the second energy storage module 12: The second charging port 3 charges the second energy storage module 12 directly or via the second DC / DC 7 module.

[0063] In one embodiment of this application, the step of controlling the second charging port 3 to be electrically connected to the second energy storage module 12 to charge the second energy storage module 12 includes: Control the second switch 6 to disconnect the second charging port 3 and the main charging port of the battery module 1, and control the second switch 6 to connect the second charging port 3 and the second DC / DC 7; The second DC / DC7 is controlled to perform voltage conversion on the power supply at the second charging port 3 in order to charge the second energy storage module 12.

[0064] Understandably, the second DC / DC7 can perform voltage conversion on the power supply at the second charging port 3 to obtain a voltage that matches the second energy storage module 12, so as to charge the second energy storage module 12.

[0065] In one embodiment of this application, the control method further includes: When the second charging port 3 is connected to a charging power source, and the first charging port 2 is not connected to a charging power source. Control the third switch 13 to connect the second energy storage module 12 and the second energy storage module 12; Control the second switch 6 to connect the second charging port 3 and the main charging port of the battery module 1, and control the second switch 6 to disconnect the second charging port 3 and the second DC / DC 7.

[0066] Power supplies capable of rapid recharging are prone to low-temperature environments during use. Therefore, this application proposes the following improvements to the method of using power supplies capable of rapid recharging in low-temperature environments: In one embodiment of this application, the power source capable of rapid power replenishment includes a battery module, a heating battery, a heat insulation component, and a first heating component. The volume of the battery module is larger than the volume of the heating battery. The heat insulation component is sleeved on the heating battery, and the first heating component is sleeved on the battery module. The heating battery is electrically connected to the first heating component, and the heating battery is used to supply power to the first heating component. The control method includes: When the battery module is in a charging / discharging state, the ambient temperature at the battery module is obtained. If the ambient temperature at the battery module is lower than a preset value, the heating battery is controlled to supply power to the first heating component so that the first heating component heats the battery module.

[0067] According to the control method of this application, when it is determined that the battery module is in a charging and discharging state, the ambient temperature at the battery module is first acquired, and the acquired ambient temperature is compared with a preset value to determine whether the ambient temperature at the battery module is lower than the preset value. When it is determined that it is lower than the preset value, it means that the ambient temperature at the battery module is too low and will affect the performance of the battery. Therefore, the heating battery is controlled to supply power to the first heating component, so that the first heating component starts to work and heats the battery module, ensuring the working ambient temperature of the battery module, avoiding the performance of the battery module from being affected by temperature, and improving the level of intelligence.

[0068] Furthermore, only the smaller heated batteries need to be fitted with insulation components, eliminating the need for insulation structures on the larger battery modules, thus reducing the space occupied by the insulation components.

[0069] Understandably, the insulation components can effectively keep the heated battery warm, ensuring that the operating temperature of the heated battery remains within a suitable range and guaranteeing the performance of the heated battery.

[0070] Understandably, if the battery module were to directly power the first heating element, the battery module's performance would be poor in low-temperature environments due to the high power consumption of the first heating element, potentially leading to a shortened battery module lifespan. Conversely, adding an insulation structure to the battery module would result in excessive space usage. Therefore, a heating battery is used to heat the first heating element to ensure the battery module's operating temperature meets the required standards.

[0071] In some examples, the insulation components are, for example, aerogel insulation materials, vacuum insulation panels, or phase change materials.

[0072] In some embodiments, the power source capable of rapid recharging further includes a second heating component, which is sleeved on the sidewall of the heating battery and located between the insulation component and the heating battery; prior to the step of controlling the heating battery to supply power to the first heating component, the method further includes: The battery module is controlled to supply power to the second heating component, so that the second heating component heats the heating battery.

[0073] It is understandable that before controlling the heating battery to supply power to the first heating component, the battery module is first controlled to supply power to the second heating component so that the heating battery can be heated by the second heating component, thereby increasing the operating temperature of the heating battery and ensuring its performance.

[0074] The preheating process ensures the heating battery operates at its optimal state, protecting its lifespan and guaranteeing the heating effect of the battery module. At low temperatures, the battery module's output power is limited, requiring only a small amount of power for preheating; the high-power heating task is still handled by the dedicated heating battery. The insulation component forms a thermal barrier during the preheating stage, concentrating the heat generated by the second heating component onto the heating battery, significantly improving preheating efficiency and reducing energy consumption.

[0075] Understandably, the second heating element is positioned between the side wall of the heating battery and the insulation element. This sandwich design ensures heating efficiency while reducing heat loss through the insulation element.

[0076] In some examples, the first heating component and the second heating component are, for example, metal thin film heating elements or carbon fiber heating layers.

[0077] In some examples, when the ambient temperature of the battery module is detected to be lower than the preset value, the battery module is first activated to supply power to the second heating component. At this time, the remaining power of the battery module is used to preheat the heating battery, so that the temperature of the heating battery rises to the optimal working range (usually above 0°C). After the temperature of the heating battery reaches the standard, the power supply to the first heating component is switched to the heating battery. At this time, the heating battery is in the optimal working state and can output electrical energy efficiently, avoiding the damage caused by the direct high current discharge of the cold heating battery.

[0078] In one embodiment of this application, the power supply capable of rapid power replenishment further includes a temperature detection element, which is disposed between the top of the heating battery and the heat preservation component; after the second step of controlling the battery module to supply power to the second heating component, the following steps are included: Based on the detection data from the temperature sensor, the temperature at the heating battery is determined; When the temperature at the heating battery reaches a preset temperature range, the battery module is controlled to stop supplying power to the second heating component.

[0079] It is understood that the power supply for rapid recharging in this application also includes a temperature detection device, which is disposed on top of the heating battery and located between the heating battery and the heat preservation component. After the control battery module supplies power to the second heating component, the following steps are performed: 1. Temperature detection and feedback Temperature sensing devices (such as NTC thermistors, thermocouples, or digital temperature sensors) monitor the temperature of the heated battery in real time and feed the detection data back to the control system (such as the BMS battery management system).

[0080] Because the temperature sensor is located on top of the heating battery (an area where heat tends to accumulate) and is encased in insulation components, its readings accurately reflect the actual operating temperature of the heating battery, avoiding interference from ambient temperature.

[0081] 2. Temperature Judgment and Control Logic The control system compares the detected temperature with a preset temperature range (e.g., 5℃~15℃): If the temperature is below the lower limit (e.g., <5℃): Continue to maintain the power supply from the battery module to the second heating component, so that the heated battery continues to heat up.

[0082] If the temperature reaches the preset range (e.g., 5℃~15℃): the control battery module stops supplying power, and the second heating component stops working.

[0083] The preset temperature range must meet the following requirements: Lower limit (e.g., 5°C): Ensure that the heated battery is removed from the low temperature state to avoid damage to its lifespan due to low-temperature discharge.

[0084] Upper limit (e.g., 15℃): to avoid overheating and energy waste, while relying on insulation components to maintain temperature stability.

[0085] 3. Insulation and self-sustaining mechanisms After the power supply is stopped, the heat preservation components effectively reduce heat loss and keep the temperature of the heating battery stable.

[0086] When the heating battery supplies power to the first heating component, the heat generated by its own internal resistance can supplement some of the heat and further maintain the temperature.

[0087] Understandably, the amount of electricity required by the second heating component is very small for the battery module and will not affect the performance of the battery module.

[0088] After the heating battery is heated to a certain temperature, the first heating element is then heated to prevent the heating battery from over-discharging and affecting its lifespan in low-temperature environments. Once the heating battery reaches the preset temperature, power to the second heating element is stopped, as the insulation component and the heating battery's own heat generation maintain a stable temperature.

[0089] In one embodiment of this application, the battery module is electrically connected to the heating battery via a DC / DC conversion module; after the step of controlling the heating battery to supply power to the first heating component, the method further includes: When the charge of the heating battery is lower than a threshold, the battery module outputs voltage to the DC / DC conversion module. The DC / DC conversion module is controlled to convert the output voltage of the battery module and supply power to the heating battery.

[0090] It is understood that in the power supply with rapid recharging capability of this application, the battery module is electrically connected to the heating battery through a DC / DC conversion module. After controlling the heating battery to supply power to the first heating component, the battery management system (BMS) monitors the state of charge (SOC) of the heating battery in real time and compares it with a preset charge threshold (such as 10%~20%).

[0091] When the heating battery's charge level falls below a threshold, it indicates insufficient energy storage, requiring replenishment from the battery module to ensure continuous power supply to the first heating component. The control system activates the battery module's output, delivering electrical energy to the DC / DC conversion module. Since the battery module's voltage (e.g., 48V) is typically higher than the heating battery's (e.g., 12V), the DC / DC conversion module performs voltage reduction to match the heating battery's charging requirements. The DC / DC conversion module converts the high-voltage DC power from the battery module into a low-voltage constant-current / constant-voltage charging mode suitable for the heating battery, preventing overcharging or voltage surges.

[0092] During charging, the temperature detection device continuously monitors the temperature of the heated battery to ensure that it is charged within a safe range (such as 0℃~30℃) to prevent lithium plating during low-temperature charging or thermal runaway during high-temperature charging.

[0093] Understandably, in this embodiment, the heating battery is prioritized for power supply to reduce the number of times the battery module directly drives the high-power load (first heating component), thus protecting its lifespan. In the on-demand power replenishment strategy of this embodiment, the battery module only intervenes through the high-efficiency DC / DC conversion module when the heating battery's charge is insufficient, reducing overall energy consumption. In other words, the battery module only undertakes low-power power replenishment tasks (through the DC / DC conversion module), avoiding damage from direct high-current discharge. The heating battery operates within a suitable temperature range, improving discharge efficiency and extending cycle life.

[0094] Understandably, if the battery module were used to power the first heating component from the beginning, the battery module's lifespan would be easily damaged due to the large power consumption of the first heating component. Therefore, a small amount of power is used first to keep the heating battery within the normal temperature range, and then the heating battery is used to power the first heating component, thus ensuring the lifespan of both batteries.

[0095] If an insulation structure were to be added to the battery module, it would result in excessive space usage. Therefore, a heating battery is used to continuously heat the first heating component to ensure that the working environment temperature of the battery module meets the standard. At the same time, the insulation structure of the battery module is eliminated, and the compact insulation component relying on the heating battery saves space.
