By configuring a power expansion compartment in the outdoor portable power bank, multiple power modules can be flexibly configured, and multiple power modules can be effectively driven by resources to achieve dynamic configuration of multiple power modules, thereby improving the flexibility of the outdoor portable power bank.

[0004] In a first aspect, embodiments of this application provide a control method for an outdoor portable power supply based on a power extension compartment, the method comprising: The system collects level detection information from multiple Class A and Class B expansion slots of the outdoor portable power bank. Based on the level detection information, it determines the number of power supply modules to be inserted into the multiple Class A expansion slots and their parallel topology. The Class B expansion slots are used to insert a display control module. The system also collects the maximum output power, current remaining power, and current operating temperature of each power supply module. Based on the current remaining power and power threshold, the available remaining power and average remaining power of each power supply module are obtained. Based on the current operating temperature of each power supply module, the average operating temperature is calculated. Based on the parallel topology, the average remaining power, the average operating temperature, and the maximum output power, the actual maximum output power is obtained. Based on the mapping relationship between the actual maximum output power and the preset power range and load type, the loadable type identifier corresponding to the actual maximum output power is determined, and the loadable type identifier is displayed in the display control module.

Furthermore, by collecting level detection information from multiple Type A and Type B expansion slots of the outdoor portable power bank, the number of power modules inserted into the multiple Type A expansion slots and their parallel topology are determined based on this information. The Type B expansion slots are used to insert a display control module. The maximum output power, current remaining power, and current operating temperature of each power module are collected. Based on the current remaining power... The system obtains the available remaining power and average remaining power of each power module based on its power level and power threshold. It also calculates the average operating temperature based on the current operating temperature of each power module. Based on the parallel topology, average remaining power, average operating temperature, and maximum output power, the actual maximum output power is obtained. Based on the mapping relationship between the actual maximum output power and a preset power range and load type, a loadable type identifier corresponding to the actual maximum output power is determined and displayed on the display control module. The system collects the first identifier of the load appliance; if the first identifier belongs to the loadable type identifier, the outdoor power bank supplies power to the load appliance. Through the above configuration, the outdoor power bank of this application can dynamically configure its power modules, greatly improving flexibility. Furthermore, it can dynamically adjust power and dynamically input charging based on actual conditions, further enhancing the flexibility of the outdoor power bank. Attached Figure Description

[0018] The following describes the relevant content, concepts, meanings, technical issues, technical solutions, and beneficial effects involved in the embodiments of this application.

[0019] LNA (Low Noise Amplifier) ​​is used to amplify weak signals and minimize the introduction of additional noise, directly determining the system's sensitivity and signal-to-noise ratio.

[0020] BMS (Battery Management System) is responsible for monitoring, protecting, balancing, and controlling the entire battery pack. Without it, lithium batteries will catch fire, explode, or have their lifespan drastically reduced.

[0021] To address the aforementioned issues, this application provides a control method and system for an outdoor portable power bank based on a power expansion compartment. For users with high requirements for flexible configuration of outdoor portable power banks, a battery expansion compartment is provided, which supports the flexible configuration of multiple power modules in terms of hardware, and a corresponding control method is configured to control the flexible configuration of multiple power modules, thereby improving flexibility.

[0022] First, please refer to the details. Figure 1 , Figure 1 This is a structural schematic diagram of a power expansion compartment for an outdoor portable power supply provided in an embodiment of this application, as shown below. Figure 1 As shown, the above scenarios include various outdoor portable power bank applications, such as camping and performance settings. Figure 1 As shown, the power expansion compartment can be configured with different outdoor power bank housings. The interior of the housing can be configured with a space matching the power expansion compartment and a pull-out or pop-out structure. The embodiments of this application are not limited to the structural type between the power expansion compartment and the outdoor power bank housing.

[0023] See Figure 1 , Figure 1 The power expansion compartment includes: multiple Class A expansion slots 10, at least one Class B expansion slot 12, and a main control unit (MCU1) 14. Each Class A expansion slot 10 is equipped with a Class A electrical and communication composite interface 11, and each Class B expansion slot 12 is equipped with a Class A electrical and communication composite interface 13. Type A expansion slot 10 is dedicated to plugging in the power supply module. The above multiple slots can be 4, 6, 8, etc., and of course, other values ​​are also possible.

[0024] For example, the above-mentioned Class A extension bit can be the Pogo Pin interface, but in other application scenarios, it can also be other interfaces.

[0025] Type B expansion slots are dedicated to connecting display control modules for interaction with master control commands and status display of the power supply module. These statuses include, but are not limited to, parameters such as: power level (remaining power, current power, total power), charging / discharging status, temperature, current, and voltage.

[0026] For example, the above-mentioned Class B extension bits can be interfaces such as CAN interface, I2C, UART serial port, etc.

[0027] The display control module has a built-in battery management system (BMS), which serves as the algorithm core and power control unit of the entire parallel system. It is responsible for parallel mode recognition, display of remaining battery power in individual cells, reminders and configuration of reserve battery power threshold, total power calculation, appliance type matching, load power distribution, and global over-discharge / overload safety management. The display control module is equipped with a touch screen that can display the remaining battery power of each power module in real time and supports user-defined reserve battery power threshold settings. The system default reserve battery power threshold is 20% (other values ​​can also be set, such as 15%).

[0028] The main control unit (MCU1) 14 is responsible for interface access detection, module identification, bus communication forwarding, and short circuit / overcurrent hardware protection.

[0029] In one alternative, each power supply module can have a built-in slave control unit (MCU2) responsible for acquiring the status of the individual module, receiving BMS scheduling instructions, and executing local power output control, while strictly adhering to the reserved power constraints issued by the BMS during the output process.

[0030] After the expansion compartment is assembled (taking 4 power supply modules and 1 display control module as an example), the system enters the multi-power parallel intelligent scheduling working mode: the display control module BMS first completes the parallel topology identification, then displays the remaining power of each power supply module on the touch screen, and reminds the user that a reserved power threshold can be set (default 20%); then, based on the reserved power constraint, the total output power is calculated, then the type of loadable electrical appliances is matched, and then the output is displayed on the screen; when an external load electrical appliance is detected to be connected, the BMS interacts with the main control unit of the load electrical appliance to exchange power requirements, and completes fine-grained power allocation by combining the real-time status of each power supply module and the reserved power threshold, and issues output configuration commands to achieve multi-module collaborative, stable and safe power output.

[0032] The intermediate layer 21 includes: a multi-battery coordination unit 210, a battery information synchronization unit 211, a power scheduling and load balancing unit 212, and a fault diagnosis and isolation unit 213. The intermediate layer 21 is used to realize plug-and-play, coordinated power supply, information synchronization, power distribution, and fault isolation of multi-battery modules, and is the core brain of the multi-battery system.

[0033] The driver layer 22 includes: BMS driver 220, extended battery driver 221, circuit parameter driver 222, and power-on and relay driver 223. The driver layer 22 is used to interface with the BMS of each battery module, read voltage, current, temperature, SOC, and SOH, and control the charge and discharge switches. The circuit parameter drivers mentioned above include, but are not limited to, voltage drivers, current drivers, and temperature drivers.

[0034] The hardware abstraction layer 23 includes: communication interface abstraction 230, GPIO abstraction 231, and ADC abstraction 232. The hardware abstraction layer 23 shields hardware differences, allowing software to adapt to different BMS, different expansion modules, and different interfaces.

[0035] In some possible embodiments, the outdoor portable power bank may specifically perform actions including... Figure 3 The methods and steps in the text, Figure 3 This is a flowchart illustrating a control method for an outdoor portable power supply based on a power extension compartment, as provided in an embodiment of this application. Figure 3 As shown, an outdoor portable power bank can perform the following steps: Step S301: Collect level detection signals of multiple Class A extension bits and Class B extension bits, and determine the number of power supply modules and parallel topology based on the level detection signals.

N This includes the number of power supply modules; a list of valid power supply module IDs; and a multi-power supply parallel mode confirmation flag. The specific calculation formula is as follows: ; MCU1 will N The valid module ID is forwarded to the BMS. The BMS establishes a communication handshake with all valid module MCU2s to confirm entry into the multi-module parallel mode of the expansion compartment.

N This represents the total number of active parallel power supply modules in the current system, a positive integer.

[0038] Step S302: Display of remaining battery power in individual units and configuration reminder for reserved battery power threshold.

[0039] The expansion compartment MCU1 obtains the real-time remaining power of each power supply module. The system retains the battery threshold by default. The touchscreen enable signal activates the expansion compartment MCU1, which controls the power display module's touchscreen to display the remaining battery power of each individual power module. The touchscreen also displays a reminder to set the reserved battery threshold, and the reserved battery threshold takes effect. .

[0040] Specific implementation method: The BMS of the outdoor portable power bank reads the remaining power of each individual unit uploaded by the MCU2. The BMS-driven touchscreen display shows the remaining battery power of each power module; the display also outputs text alerts. The system has entered multi-power parallel mode. The remaining power of each module is now displayed. The power reserve threshold can be customized. The default power reserve threshold is 20%. The touch configuration entry is enabled to receive the user-defined power reserve threshold. The BMS locks this power reserve threshold as a mandatory constraint for subsequent power calculation and output.

[0041] in, : No. i The current remaining power of each power module, percentage, 0~100%; The final effective power retention threshold, percentage, and over-discharge protection red line for the system; The system default power threshold is a constant, typically set to 20%. The percentage of battery capacity that can be reserved is a user-defined threshold for battery level retention via the touchscreen.

[0042] Step S303: Calculate the maximum output power of the system with reserved power constraints.

[0043] The expansion compartment MCU1 obtains the rated maximum output power of a single power supply module. , No. i The current remaining power of each power module No. iCurrent operating temperature of each power supply module Effective retention power threshold The system has a preset safety factor range. The actual maximum output power of the system .

[0044] Specific calculation method: The expansion compartment MCU1 calculates the remaining available power of a single unit (after deducting reserved power). The specific calculation formula is as follows: ; like If so, the module will be prohibited from output.

[0045] Calculate the theoretical total rated power of all modules: ; Calculate the module's average remaining power and average operating temperature: ; ; Introducing a temperature-available power coupling safety factor The actual maximum output power with reserved charge constraint is obtained by correction: ; like If the value is 0, then set it to 0 and output a low battery alarm.

[0046] in, The rated maximum output power of a single power supply module, in watts (W). For the first i The percentage of available remaining power after deducting reserved power for each module; Average remaining battery power, percentage, for all modules; This represents the percentage of maximum usable battery capacity when fully charged. The average operating temperature of all parallel modules, in °C; The system safety factor is a floating-point number. The actual maximum safe output power of the system with reserved charge constraints, in watts (W).

[0047] Step S304: Match the type of loadable electrical appliance with the display screen output.

[0048] Specifically, the expansion compartment's MCU1 obtains the actual maximum output power. The power range and loadable appliance type identifier library pre-stored in the BMS outputs a set of loadable appliance types; the display screen shows the drive instructions.

[0049] Specific implementation plan: BMS traverses the database and matches power ranges that satisfy: ; Extract the loadable electrical appliance type identifier corresponding to this range. ; BMS will The data is sent to the touchscreen display of the display control module for visual output.

[0051] Step S305: Load appliance connection detection and target power requirement confirmation.

[0052] Specifically, the expansion compartment MCU1 acquires the hardware detection level signal of the load electrical appliance, the communication data frame between the BMS and the load electrical appliance MCU, and the actual maximum output power of the system. Output load target output power A flag indicating whether load adaptation was successful or failed.

[0053] The specific implementation method is as follows: The BMS reads the rated power requirement of the load appliances through the communication protocol. ; Execute power validity check: ; If the verification passes, a load adaptation success flag is generated; if the verification fails, an overload alarm is output.

[0054] in, The rated power demand reported by the load electrical appliances, in watts (W). The final confirmed target output power for the load, expressed in watts (W).

[0055] Step S306: Calculate the power output configuration of a single power supply module with reserved power constraints.

[0056] Expanding compartment MCU1 obtains the target output power of the load.

[0057] Specific implementation method: The expansion compartment MCU1 calculates the basic amortized output power: ; By introducing a correction factor for available remaining power, the corrected output power of a single module is obtained: ; Perform a strong constraint check on the reserved power capacity: ; in t To estimate the discharge duration, This is the conversion factor for battery capacity and power.

[0058] Calculate the output voltage and current configuration of a single module: ; in, For the first i The average power per module, in watts (W). For the first i The final output power of each module is configured, in watts (W). The required operating voltage for the load electrical appliance, in volts (V). For the first i Each module is configured with an output voltage, in volts (V). For the first i Each module is configured with output current, in amperes (A). The estimated discharge duration is expressed in hours (h). : Conversion factor between battery capacity and power, unit: Wh.

[0059] Step S307: Power output execution and real-time closed-loop monitoring.

[0060] The expansion compartment's MCU1 acquires the output configuration parameters of each power supply module, as well as the module's real-time voltage, current, temperature, and SOC values. It also retains power threshold values. The expansion compartment MCU1 receives stable power output from the load end, real-time system operating status feedback frames, and abnormal protection lockout commands.

[0061] Specific implementation method: The BMS sends configuration commands to MCU1 in the expansion compartment, and MCU1 forwards them to the corresponding MCU2; each MCU2 then... Execute power output; BMS collects operating parameters in real time, and if the remaining power is lower than the retention threshold or the electrical parameters exceed the limit, the output is locked.

[0062] in, Maximum permissible operating temperature of the battery pack, constant, unit: °C.

[0063] Compared to existing portable power banks with a fixed number of power modules, which results in limited flexibility due to their inability to dynamically configure size and weight, this application's technical solution addresses this issue by setting up Type A and Type B expansion slots. This allows for arbitrary configuration of the power modules. Furthermore, by collecting level detection information from multiple Type A and Type B expansion slots, the number of power modules inserted into the multiple Type A expansion slots and their parallel topology are determined based on this information. The Type B expansion slots are used to insert a display control module. The maximum output power, current remaining power, and current operating temperature of each power module are collected. Based on the current remaining power... The system obtains the available remaining power and average remaining power of each power module based on a power threshold, and calculates the average operating temperature based on the current operating temperature of each power module. Based on the parallel topology, average remaining power, average operating temperature, and maximum output power, the actual maximum output power is obtained. Based on the mapping relationship between the actual maximum output power and a preset power range and load type, the system determines the loadable type identifier corresponding to the actual maximum output power and displays the loadable type identifier on the display control module. The system collects the first identifier of the load appliance; if the first identifier belongs to the loadable type identifier, the outdoor power bank controls the outdoor power bank to supply power to the load appliance. Through the above configuration, the outdoor power bank of this application can dynamically configure the power modules, greatly improving flexibility, and dynamically adjusting the power and charging input according to actual conditions, thus enhancing the flexibility of the outdoor power bank.

The total number of positive level detection information is determined as the number of power supply modules. All valid power supply modules are connected in parallel to obtain the parallel topology.

[0067] In one optional scheme, the actual maximum output power is obtained based on the parallel topology, the average remaining power, the average operating temperature, and the maximum output power, specifically including: The output power is determined by superposition operation based on the parallel topology relationship. Based on the superposition operation, the average remaining power, the average operating temperature and the maximum output power, the actual maximum output power is obtained. The specific calculation includes: the actual maximum output power is the product of the rated power of a single power supply module, the system safety factor, the number of power supply modules, the temperature correction function, and the ratio of the average remaining power of the power supply module to the electrical connection threshold margin. The temperature correction function decreases linearly as the absolute value of the deviation between the average operating temperature and the operating temperature corresponding to the maximum output power increases, and is used to temperature-constrain the maximum output power of the power supply module to obtain the safe and usable power at the current temperature.

Based on the target output power of the load, the remaining power and operating temperature of each power supply module, the actual output power of each power supply module is determined, and the output current of each power supply module is determined based on the actual output power.

[0070] In one optional scheme, determining the actual output power of each power supply module based on the target output power of the load, the remaining power and operating temperature of each power supply module specifically includes: the actual output power of any power supply module is the product of the target output power of the load, the remaining power of any power supply module, and the temperature correction function of any power supply module, divided by the sum of the products of the remaining power and temperature correction functions of all power supply modules. The temperature correction function decreases linearly as the absolute value of the deviation between the average operating temperature and the operating temperature corresponding to the maximum output power increases, and is used to temperature-constrain the maximum output power of the power supply module to obtain the safe and usable power at the current temperature.

The circuit parameters include: remaining power, current, and voltage.

[0073] In an optional embodiment, the method further includes: determining the safe output power value based on the actual maximum output power, temperature safety factor, voltage safety factor, and temperature difference safety factor, specifically including: The safe output power value is the product of the cumulative product and the actual maximum output power. The cumulative product is the product obtained by performing a cumulative multiplication operation on the temperature safety factor, voltage safety factor and temperature difference safety factor. The temperature safety factor is 1 when the temperature of the power supply module is within the preset temperature range, less than 1 when the temperature is greater than the preset temperature range but less than the fire protection threshold, and decreases linearly or non-linearly as the temperature of the power supply module deviates from the preset temperature range. When the temperature of the power supply module is greater than the fire protection threshold, the temperature safety factor is 0. The voltage safety factor is 1 when the voltage of the power supply module is within a preset voltage range, and 0 otherwise.
