Technical Field

[0002] As a portable energy storage device, an outdoor power supply is widely used in scenarios such as camping, emergency power supply, and outdoor operations. Its charging efficiency directly affects the user experience.

[0003] In related technologies, an outdoor power supply usually configures a single charging port (such as a solar charging interface, a mains power interface, etc.), and the charging power is limited by the maximum input capacity of this port. For example, in a single charging mode, if the user only connects one power source (such as a solar panel or an adapter), the charging speed is limited by the port power. Especially in an outdoor power supply with a large battery capacity, the charging time is significantly extended, making it difficult to meet the demand for rapid charging in outdoor scenarios.

[0040] To make the objectives, technical solutions, and advantages of the present application clearer, the following will clearly and completely describe the technical solutions in the present application with reference to the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0041] The embodiments of the present application provide embodiments of the outdoor power supply energy storage control method. It should be noted that although the logical order is shown in the flowchart, under certain data, the steps shown or described can be completed in a different order than here.

[0042] Before introducing the outdoor power supply energy storage control method according to the embodiments of the present application, first, an application scenario of the outdoor power supply energy storage control method is explained. The outdoor power supply energy storage control method of the present application can be applied to intelligent terminals such as smart phones, tablets, and computers, and can also be applied to servers. The present application does not make special limitations here, as long as it can carry and implement the outdoor power supply energy storage control method of the present application.

[0043] The following takes the application of the outdoor power supply energy storage control method to the server side as an example for illustration. However, it should be understood that the outdoor power supply energy storage control method is not limited to being applied only to the server side.

[0044] The following combines Figures 1 to 4 to describe the outdoor power supply energy storage control method, power module, and electronic device of the present application.

[0045] According to an embodiment of the first aspect of the present application, as Figure 1 and Figure 2 shown, for the outdoor power supply energy storage control method, the outdoor power supply includes a battery module 1, the battery module 1 includes a first battery pack 11, a second battery pack 12, and a third switch 13, the third switch 13 is electrically connected between the first battery pack 11 and the second battery pack 12, and the outdoor power supply has a first charging port 2 and a second charging port 3; the outdoor power supply energy storage control method includes:

[0046] Step 101, determining that charging power supplies are connected to both the first charging port 2 and the second charging port 3;

[0047] Step 102, controlling the third switch 13 to disconnect the connection between the first battery pack 11 and the second battery pack 12;

[0048] Step 103, controlling the first charging port 2 to be electrically connected to the first battery pack 11 to charge the first battery pack 11;

[0049] Step 104, controlling the second charging port 3 to be electrically connected to the second battery pack 12 to charge the second battery pack 12.

[0050] According to the outdoor power supply energy storage control method of the present application, the battery module 1 is provided with a first charging port 2 and a second charging port 3, and both the first charging port 2 and the second charging port 3 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 battery group 11 and the second battery group 12, so that the first battery group 11 and the second battery group 12 are independent of each other. Then, the first charging port 2 is controlled to be electrically connected to the first battery group 11 to charge the first battery group 11 with the charging power source at the first charging port 2, and the second charging port 3 is controlled to be electrically connected to the second battery group 12 to charge the second battery group 12 with the charging power source at the second charging port 3. Thus, charging the outdoor power supply with dual power sources is realized, the charging speed of the outdoor power supply is increased, the replenishment time of the outdoor power supply is shortened, and the user's demand for rapid replenishment can be met.

[0051] It can be understood that in the related art, the battery module 1 has only one charging port, and thus can only be charged with one charging power source. In the present application, the 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 battery group 11 and the second battery group 12, so that the charging power source directly charges the entire outdoor 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 battery group 11 and the second battery group 12, so that the first battery group 11 and the second battery group 12 are independent of each other. Thus, one of the charging power sources can be used to charge the first battery group 11, and the other charging power source can be used to charge the second battery group 12, realizing dual - power charging and increasing the charging speed.

[0052] In some examples, the third switch 13 is a controllable relay or a MOSFET switch, controlled by a control module, and is used to conduct or disconnect the electrical connection between the first battery group 11 and the second battery group 12.

[0053] In some examples, when implementing the outdoor power supply energy storage control method,

[0054] First, the connection states of the dual charging ports are detected. The control module monitors the connection states 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 effective charging power sources (for example, the first port is connected to a solar input voltage ≥ 18V, and the second port is connected to a mains adapter voltage of 220V), the dual - port charging mode is triggered.

[0055] Then, battery pack isolation control is performed. The control module sends a disconnection instruction to the third switch 13 to completely disconnect the electrical connection between the first battery pack 11 and the second battery pack 12, forming two independent charging circuits. This is to avoid mutual charging or energy loss between the two battery packs due to voltage differences, and at the same time eliminate the risk of mutual interference between power sources during parallel charging.

[0056] Then, dynamic allocation of the charging circuit is carried out. The first charging port 2 is connected to the first battery pack 11: The control module closes the access switch (such as MOS transistor Q1) of the first charging port 2, directly connects the input power source (such as solar energy) of the first charging port 2 to the positive and negative electrodes of the first battery pack 11, and charges the first battery pack 11 through a charging management circuit (such as an MPPT controller). The second charging port 3 is connected to the second battery pack 12: Synchronously close the access switch (such as MOS transistor Q2) of the second charging port 3, connect the input power source (such as a mains adapter) of the second charging port 3 to the positive and negative electrodes of the second battery pack 12, and charge the second battery pack 12 in constant voltage / constant current (CV / CC) mode.

[0057] Furthermore, the present application specifically has at least the following technical effects:

[0058] Dual-port power superposition: By disconnecting the third switch 13, the battery packs are divided into independent units, enabling the two charging ports to supply power to different battery packs simultaneously. The total input power is the sum of the powers of the two ports (for example, solar input 300W + mains input 500W = total input 800W), breaking through the single-port power limit and significantly shortening the charging time.

[0059] Power supply compatibility guarantee: When the two charging ports are connected to power sources with different characteristics (such as unstable solar energy and stable mains power), due to battery pack isolation, voltage conflicts between power sources are avoided, and each adapts to the battery requirements through an independent charging management circuit.

[0060] The following is an illustration of the present application in combination with an actual scenario:

[0061] Assume that the total capacity of an outdoor power supply is 2000Wh, and the maximum input power of a single port is 500W. For traditional single-port charging, it takes 4 hours to fully charge. After adopting this method, if both ports input simultaneously (solar 300W + mains 500W), the total power is increased to 800W, the charging time is shortened to about 2.5 hours, and the efficiency is increased by about 37.5%.

[0062] In some embodiments, the outdoor power supply 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 battery pack 11 are electrically connected in sequence. The total charging port of the battery module 1 is electrically connected to the first switch 4. The first switch 4 can be switched between a first state and a second state. In the first state, the first switch 4 connects the first charging port 2 and the total 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.

[0063] It can be understood that the first switch 4 is a two-way switching switch (such as a relay or a MOS tube combination), controlled by the control module, and has two states: the first state (direct connection mode), directly connecting the first charging port 2 and the total charging port of the battery module 1, and the input power supply directly charges the entire battery module 1; the second state (DC / DC mode): connecting the first charging port 2 to the input end of the first DC / DC 5 module, and the output end of the first DC / DC 5 is connected to the independent charging port of the first battery pack 11. The first DC / DC 5 module is a buck-boost type DC / DC converter, used to adjust the input voltage to match the battery pack requirements (such as boosting the unstable low voltage of the solar panel to the battery pack charging voltage).

[0064] It can be understood that when only the first charging port 2 is connected to a high-voltage power supply such as an adapter, the DC / DC module is bypassed through the direct connection mode, reducing energy conversion losses (such as the DC / DC efficiency is about 95%, and the direct connection efficiency

[0065] ≈100%), achieving fast charging. When the first charging port 2 and the second charging port 3 are connected to the power supply at the same time, the input of the first charging port 2 is restricted to charge the first battery pack 11 through the switching of the first switch 4, and the second charging port 3 independently charges the second battery pack 12, realizing the superposition of the power of the two power supplies. The input power of the two ports is independently allocated to different battery packs, and the total charging power is the sum of the powers of the two ports (for example, solar 300W + mains 500W = 800W), and the charging time is shortened by about 37.5% compared with single-port charging.

[0066] In some examples, when the first charging port 2 is connected to a low-voltage power supply (such as solar energy), it is boosted through the DC / DC module to ensure the effective utilization of the input power.

[0067] In some examples, when a charging power supply is connected to a single charging port (for example, only the first charging port 2 is connected to the power supply):

[0068] The control module detects that the second charging port 3 is not connected to an effective power supply, and the input of the first charging port 2 is effective (such as voltage ≥ 5V).

[0069] The control module judges the type of the input power supply:

[0070] If the input voltage matches the total charging port voltage of the battery module 1 (for example, the output of the mains adapter is 54.6V corresponding to a 48V battery pack), the first switch 4 is controlled to switch to the first state (direct connection mode), and the input power supply directly charges the entire battery module 1 through the total charging port.

[0071] If the input voltage does not match (for example, solar input is 18V), the first switch 4 is controlled to switch to the second state (DC / DC mode), and the input power supply is adjusted by the first DC / DC 5 module and then charges the first battery pack 11.

[0072] When charging power supplies are connected to both the first charging port 2 and the second charging port 3:

[0073] The control module detects that valid power supplies are connected to both ports and triggers the dual-port charging mode.

[0074] The first switch 4 switches to the second state (DC / DC mode): The first charging port 2 charges the first battery pack 11 through the first DC / DC 5 module.

[0075] The second charging port 3 is directly connected to the second battery pack 12: The second charging port 3 directly or charges the second battery pack 12 through the second DC / DC 7 module.

[0076] Specifically, the step of controlling the first charging port 2 to be electrically connected to the first battery pack 11 to charge the first battery pack 11 includes:

[0077] Control the first switch 4 to disconnect the first charging port 2 and the total 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;

[0078] Control the first DC / DC 5 to perform voltage conversion on the power supply at the first charging port 2 to charge the first battery pack 11.

[0079] It can be understood that the first DC / DC 5 can perform voltage conversion on the power supply at the first charging port 2 to obtain a voltage matching the first battery pack 11 to charge the first battery pack 11.

[0080] In an embodiment of the present application, the outdoor power supply energy storage control method further includes:

[0081] When a charging power supply is connected to the first charging port 2 and no charging power supply is connected to the second charging port 3,

[0082] Control the third switch 13 to connect the first battery pack 11 and the second battery pack 12;

[0083] Control the first switch 4 to connect the first charging port 2 and the total 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.

[0084] It can be understood that 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 an effective power source (such as voltage ≥ 5V) and the second charging port 3 is not connected to a power source, the single-port charging mode is triggered. A closing instruction is sent to the third switch 13 (S3) to connect the first battery pack 11 and the second battery pack 12 together to form a unified battery module 1. The control module controls the first switch 4 to switch to the first state (direct connection mode), that is: disconnect the connection between the first charging port 2 and the first DC / DC 5 module; directly connect the first charging port 2 to the total charging port of the battery module 1.

[0085] That is to say, when only the first charging port 2 is connected to a high-voltage power source such as an adapter, the two battery packs are connected together by closing the third switch 13, and the first switch 4 is used to directly connect to the total charging port, and the input power source directly charges the entire battery module 1. Bypassing the energy conversion loss of the DC / DC module (efficiency ≈ 100%), the charging speed is maximized, the equivalent capacity of the battery pack is increased, and a higher input current can be accepted (for example, the current limit of a single battery pack is 10A, and the current limit is 20A after parallel connection).

[0086] In an embodiment of the present application, the outdoor power supply 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 battery pack 12 are electrically connected in sequence. The total charging port of the battery module 1 is electrically connected to the second switch 6. The second switch 6 can be switched between a third state and a fourth state. In the third state, the second switch 6 connects the second charging port 3 and the total 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.

[0087] It can be understood that the second switch 6 is a two-way switching switch (such as a relay or a MOS tube combination), controlled by the control module, and has two states: the third state (direct connection mode), directly connecting the second charging port 3 to the total charging port of the battery module 1, and the input power source directly charges the entire battery module 1; the fourth state (DC / DC mode): connecting the second charging port 3 to the input end of the second DC / DC 7 module, and the output end of the second DC / DC 7 is connected to the independent charging port of the second battery pack 12. The second DC / DC 7 module is a buck-boost type DC / DC converter, which is used to adjust the input voltage to match the battery pack requirements (such as boosting the unstable low voltage of the solar panel to the battery pack charging voltage).

[0088] It can be understood that when only the second charging port 3 is connected to a high-voltage power source such as an adapter, the DC / DC module is bypassed through the direct connection mode, reducing energy conversion losses (for example, the DC / DC efficiency is about 95%, and the direct connection efficiency

[0089] ≈100%), enabling fast charging. When the first charging port 2 and the second charging port 3 are both connected to a power source, the input of the second charging port 3 is restricted to charge the second battery pack 12 by switching through the second switch 6, and the first charging port 2 independently charges the first battery pack 11, realizing the superposition of the power of two power sources. The input power of the two ports is independently allocated to different battery packs, and the total charging power is the sum of the powers of the two ports (for example, solar 300W + mains 500W = 800W), shortening the charging time by about 37.5% compared to single-port charging.

[0090] In some examples, when the second charging port 3 is connected to a low-voltage power source (such as solar energy), it is boosted through the DC / DC module to ensure the effective utilization of the input power.

[0091] In some examples, when there is a charging power source connected to a single charging port (for example, only the second charging port 3 is connected to a power source):

[0092] The control module detects that the first charging port 2 is not connected to an effective power source, and the input of the second charging port 3 is effective (such as voltage ≥ 5V).

[0093] The control module determines the type of the input power source:

[0094] If the input voltage matches the total charging port voltage of the battery module 1 (for example, the output of the mains adapter is 54.6V corresponding to a 48V battery pack), then control the second switch 6 to switch to the third state (direct connection mode), and the input power source directly charges the entire battery module 1 through the total charging port.

[0095] If the input voltage does not match (such as solar input 18V), then control the second switch 6 to switch to the fourth state (DC / DC mode), and the input power source is adjusted by the second DC / DC 7 module and then charges the second battery pack 12.

[0096] When charging power sources are connected to both the first charging port 2 and the second charging port 3:

[0097] The control module detects that effective power sources are connected to both ports and triggers the dual-port charging mode.

[0098] The second switch 6 switches to the fourth state (DC / DC mode): The second charging port 3 charges the second battery pack 12 through the first DC / DC 5 module.

[0099] The second charging port 3 is directly connected to the second battery pack 12: The second charging port 3 charges the second battery pack 12 directly or via the second DC / DC 7 module.

[0100] In an embodiment of the present application, the step of controlling the electrical connection between the second charging port 3 and the second battery pack 12 to charge the second battery pack 12 includes:

[0101] Control the second switch 6 to disconnect the total charging port of the second charging port 3 and the battery module 1, and control the second switch 6 to connect the second charging port 3 and the second DC / DC 7;

[0102] Control the second DC / DC 7 to perform voltage conversion on the power supply at the second charging port 3 to charge the second battery pack 12.

[0103] It can be understood that the second DC / DC 7 can perform voltage conversion on the power supply at the second charging port 3 to obtain a voltage matching the second battery pack 12 to charge the second battery pack 12.

[0104] In an embodiment of the present application, the outdoor power supply energy storage control method further includes:

[0105] When the second charging port 3 is connected to a charging power supply and the first charging port 2 is not connected to a charging power supply,

[0106] Control the third switch 13 to connect the second battery pack 12 and the second battery pack 12;

[0107] Control the second switch 6 to connect the second charging port 3 and the total 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.

[0108] When the outdoor power supply is in use, it is prone to encounter a low-temperature environment. Therefore, the present application proposes the following improvements to the method of using the outdoor power supply in a low-temperature environment:

[0109] In an embodiment of the present application, the outdoor power supply includes a battery module, a heating battery, a heat preservation component, and a first heating component. The volume of the battery module is larger than the volume of the heating battery. The heat preservation 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 outdoor power supply energy storage control method includes:

[0110] When the battery module is in a charging and discharging state, obtain the ambient temperature at the battery module;

[0111] If the ambient temperature at the battery module is lower than a preset value, control the heating battery to supply power to the first heating component so that the first heating component heats the battery module.

[0112] According to the outdoor power supply energy storage control method of the present application, when it is determined that the battery module is in a charging and discharging state, first obtain the ambient temperature at the battery module, compare the obtained ambient temperature with the preset value to determine whether the ambient temperature at the battery module is lower than the preset value. When it is determined to be lower than the preset value, it indicates that the ambient temperature at the battery module is too low at this time, which will affect the performance of the battery. Therefore, control the heating battery to supply power to the first heating component, so that the first heating component starts to work, realizing the heating of the battery module, ensuring the working ambient temperature of the battery module, avoiding the performance of the battery module being affected by temperature, and at the same time improving the degree of intelligence.

[0113] Moreover, only need to set a heat preservation component for the relatively small heating battery, without setting a heat preservation structure for the relatively large battery module, reducing the space occupied by the heat preservation components.

[0114] It can be understood that the heat preservation component can effectively play a heat preservation role for the heating battery, so that the working ambient temperature of the heating battery can be maintained in a suitable temperature range, ensuring the performance of the heating battery.

[0115] It can be understood that if the battery module is directly used to supply power to the first heating component, since the power consumption of the first heating component is large, and the performance of the battery module is poor in a low-temperature environment, it is easy to damage the life of the battery module. If a heat preservation structure is set for the battery module, it will cause the problem of excessive space occupation. Therefore, the heating battery is used to heat the first heating component to ensure that the working ambient temperature of the battery module meets the standard.

[0116] In some examples, the heat preservation component is, for example, aerogel thermal insulation material or vacuum insulation panel or phase change material.

[0117] In some embodiments, the outdoor power supply further includes a second heating component, the second heating component is sleeved on the side wall of the heating battery, and the second heating component is located between the heat preservation component and the heating battery; before the step of controlling the heating battery to supply power to the first heating component, it further includes:

[0118] Control the battery module to supply power to the second heating component so that the second heating component heats the heating battery.

[0119] It can be understood 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 through the second heating component, thereby improving the working environmental temperature of the heating battery and ensuring the performance of the heating battery.

[0120] Through the preheating link, it is ensured that the heating battery works in the best state, which not only protects the service life of the heating battery but also ensures the heating effect of the battery module. The output power of the battery module is limited at low temperatures, and only a small power is required to complete the preheating. The high-power heating task is still borne by the dedicated heating battery. The heat preservation component forms a heat insulation barrier during the preheating stage, enabling the heat generated by the second heating component to act concentratedly on the heating battery, significantly improving the preheating efficiency and reducing energy consumption.

[0121] It can be understood that the second heating component is arranged between the side wall of the heating battery and the heat preservation component. This sandwich design can not only ensure the heating efficiency but also reduce heat dissipation through the heat preservation component.

[0122] In some examples, the first heating component and the second heating component are, for example, metal thin film heating sheets or carbon fiber heating layers.

[0123] In some examples, when it is detected that the ambient temperature of the battery module is 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 heating battery is switched to supply power to the first heating component. At this time, the heating battery is in the best working state and can efficiently output electric energy, avoiding damage caused by direct large-current discharge of the cold-state heating battery.

[0124] In an embodiment of the present application, the outdoor power supply further includes a temperature detection component, and the temperature detection component is arranged between the top of the heating battery and the heat preservation component; after the step of controlling the battery module to supply power to the second heating component, it includes:

[0125] Based on the detection data of the temperature detection component, determine the temperature at the heating battery;

[0126] When the temperature at the heating battery reaches the preset temperature range, control the battery module to stop supplying power to the second heating component.

[0127] It can be understood that the outdoor power supply of the present application further includes a temperature detection component, and this temperature detection component is arranged at the top of the heating battery and is located between the heating battery and the heat preservation component. After controlling the battery module to supply power to the second heating component, the following steps are performed:

[0128] 1. Temperature detection and feedback

[0129] The temperature detection component (such as an NTC thermistor, a thermocouple or a digital temperature sensor) monitors the temperature of the heating battery in real time and feeds the detected data back to the control system (such as a BMS battery management system).

[0130] Since the temperature detection component is located at the top of the heating battery (an area where heat is likely to accumulate) and is wrapped by the heat insulation component, its detected value can accurately reflect the actual working temperature of the heating battery and avoid the interference of the ambient temperature.

[0131] 2. Temperature Judgment and Control Logic

[0132] The control system compares the detected temperature with a preset temperature range (such as 5°C to 15°C):

[0133] If the temperature is lower than the lower limit (such as <5°C): Continue to maintain the power supply of the battery module to the second heating component to keep the heating battery heating up continuously.

[0134] If the temperature reaches the preset range (such as 5°C to 15°C): Control the battery module to stop power supply and the second heating component to stop working.

[0135] This preset temperature range needs to meet:

[0136] Lower limit (such as 5°C): Ensure that the heating battery gets out of the low-temperature state and avoid damage to its life caused by low-temperature discharge.

[0137] Upper limit (such as 15°C): Avoid energy waste caused by overheating. At the same time, rely on the heat insulation component to maintain the temperature stability.

[0138] 3. Heat Insulation and Self-Sustaining Mechanism

[0139] After the power supply is stopped, the heat insulation component effectively reduces the heat dissipation and keeps the temperature of the heating battery stable.

[0140] When the heating battery powers the first heating component later, the heat generated by its own internal resistance can supplement part of the heat to further maintain the temperature.

[0141] It can be understood that the power required by the second heating component accounts for a very low proportion of the battery module and will not affect the performance of the battery module.

[0142] After heating the temperature of the heating battery to a certain level, heat the first heating component to avoid over-discharging of the heating battery in a low-temperature environment, which affects its life. After the temperature of the heating battery reaches the preset temperature, stop power supply to the second heating component. Because there is a heat insulation component and the heat generated by the heating battery itself, the temperature can be kept stable.

[0143] In one embodiment of the present application, the battery module is electrically connected to the heating battery through a DC / DC conversion module; after the step of controlling the heating battery to supply power to the first heating component, the following steps are further included:

[0144] When the power of the heating battery is lower than a threshold value, control the battery module to output voltage to the DC / DC conversion module;

[0145] Control the DC / DC conversion module to convert the output voltage of the battery module and supply power to the heating battery.

[0146] It can be understood that in the outdoor power supply of the present 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 power (SOC) of the heating battery in real time and compares it with a preset power threshold value (such as 10% - 20%).

[0147] When the power of the heating battery is lower than the threshold value, it indicates that its energy storage is insufficient and the battery module needs to supply power to ensure the continuous power supply of the first heating component. The control system starts the output of the battery module and delivers electrical energy to the DC / DC conversion module. The voltage of the battery module (such as 48V) is usually higher than that of the heating battery (such as 12V), so the DC / DC conversion module performs a step-down process to match the charging requirements of the heating battery. The DC / DC conversion module converts the high-voltage direct current of the battery module into a low-voltage constant current / constant voltage charging mode suitable for the heating battery to avoid overcharging or voltage impact.

[0148] During the charging process, the temperature detection component continuously monitors the temperature of the heating battery to ensure that it is charged within a safe range (such as 0°C - 30°C) to prevent lithium deposition during low-temperature charging or thermal runaway at high temperatures.

[0149] It can be understood that in this embodiment, the heating battery is preferentially used for power supply: reducing the number of times the battery module directly drives a high-power load (the first heating component) and protecting its lifespan. In the on-demand power supply replenishment strategy of this embodiment: only when the power of the heating battery is insufficient, the battery module intervenes through an efficient DC / DC conversion module to reduce the overall energy consumption. That is to say, the battery module only undertakes a small-power power supply replenishment task (through the DC / DC conversion module) to avoid damage caused by direct large-current discharge. The heating battery operates in a suitable temperature range, improving the discharge efficiency and extending the cycle life.

[0150] It can be understood that if the battery module is used to supply power to the first heating component at the beginning, since the power consumption of the first heating component is large, it is easy to damage the lifespan of the battery module. Therefore, a small amount of power is first used to make the heating battery in a normal temperature range, and then the heating battery is used to supply power to the first heating component, ensuring the lifespan of both batteries.

[0151] If a thermal insulation structure is provided for the battery module, it will cause the problem of excessive space occupation. Therefore, the 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 thermal insulation structure of the battery module is omitted, and the compact thermal insulation component relying on the heating battery saves space.
