Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a control method for energy storage power supply and its power distribution. Background Technology

[0002] Energy storage power supplies can provide stable AC / DC voltage output and are equipped with various DC output interfaces, such as Type-C, USB-A, and car chargers. These DC output interfaces are used in various scenarios, including single-port use, multi-port combination use, and real-time adjustment of discharge power for each DC port based on its temperature. To achieve discharge power management under these complex conditions, related technologies utilize preset power allocation strategies to adjust the output power of each interface.

[0003] However, the control nature of conventional power distribution schemes means that their distribution logic is relatively fixed, making it difficult to balance user experience and device safety. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the related art. Therefore, this application provides a control method for energy storage power sources and their power distribution.

[0005] This application proposes a discharge power distribution control method for an energy storage power supply, the energy storage power supply including at least two power interfaces configured to connect to an external device for charging the external device, the discharge power distribution control method including: Obtain at least two of the following for each power interface: actual output power, temperature, specifications, and real-time power of the energy storage power source; Based on the actual output power, temperature, and specifications of the power interface, as well as the real-time power of the energy storage power source, the preset discharge power is determined. If the actual output power is less than the current discharge power setting value, the current discharge power setting value shall be used as the target discharge power setting value; or If the actual output power is greater than or equal to the current discharge power setting value, the target discharge power setting value is determined based on the preset discharge power and the current discharge power setting value.

[0006] In some implementations, a preset discharge power is determined based on the specifications, usage status, and temperature of the power interface, as well as the real-time power level of the energy storage power source, including: The first preset power of the power interface is set based on the aforementioned specifications. The second preset power of the power interface is set based on the usage state; The third preset power of the power interface is determined based on the temperature; The fourth preset power of the power interface is determined based on the real-time power of the energy storage power source. The minimum value among the first preset power, the second preset power, the third preset power, and the fourth preset power is taken as the preset discharge power.

[0007] In some implementations, setting a first preset power for the power interface based on the specified parameters includes: The output power of the power interface when the energy storage power supply is powered on is taken as the first preset power.

[0008] In some implementations, setting a second preset power for the power interface based on the usage state includes: The current output mode of the power interface is determined based on the usage status; The maximum output power corresponding to the current output mode is used as the second preset power.

[0009] In some implementations, determining the current output mode of the power interface based on the usage state includes: The usage status of each power interface is determined based on the actual output power of the power interface. The output mode of each power interface is determined based on its usage status.

[0010] In some implementations, determining the usage status of each power interface based on its actual output power includes: If the actual output power of the power interface is greater than 0W, the power interface is determined to be in operation. If the actual output power of the power interface is 0W, the power interface is determined to be in an unloaded state.

[0011] In some implementations, determining a third preset power for the power interface based on the temperature includes: The maximum output power of the power interface at the specified temperature is taken as the third preset power.

[0012] In some embodiments, when the actual output power is greater than or equal to the current discharge power setting value, determining the target discharge power setting value based on the preset discharge power and the current discharge power setting value includes: Compare the preset discharge power with the current discharge power setting value; If the current discharge power setting is greater than or equal to the preset discharge power, the preset discharge power is used as the target discharge power setting; or If the current discharge power setting is less than the preset discharge power, the current discharge power setting is used as the target discharge power setting.

[0013] In some embodiments, the power interface includes at least one of a Type-C interface, a USB-A interface, and a car charger interface.

[0014] This application also proposes an energy storage power source, including a controller, which is used to execute the power distribution control method described in any of the above embodiments.

[0015] The energy storage power supply discharge power distribution control method and energy storage power supply proposed in this application determine the preset discharge power by obtaining at least two parameters from each power interface, including the actual output power, temperature, specification parameters, and real-time power. When the actual output power is less than the current discharge power setting value, the current setting value is maintained to avoid unnecessary derating. When the actual output power is greater than or equal to the current discharge power setting value, power limiting is implemented based on the smaller of the preset discharge power and the current setting value. In this way, on the one hand, multi-dimensional constraints are comprehensively considered, and power is limited in a timely manner when the temperature rises or the power is insufficient, effectively preventing safety issues such as overheating and over-discharge. On the other hand, when the actual demand of external devices is small, derating is not performed, avoiding the user's perception of a slower charging speed and greatly improving the user experience. In addition, this application adopts simple logical judgment, without the need for complex algorithms and iterative calculations, with fast response speed, low requirements for controller computing power, and easy deployment and implementation in portable energy storage power supplies.

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] Please see Figure 1 This application proposes a discharge power distribution control method for an energy storage power supply. The energy storage power supply includes at least two power interfaces configured to connect to external devices for charging. The discharge power distribution control method includes: 01. Obtain at least two of the following for each power interface: actual output power, temperature, specifications, and real-time power of the energy storage power supply. 02. Determine the preset discharge power based on the actual output power, temperature, and specifications of the power interface, as well as the real-time power of the energy storage power supply. 03. If the actual output power is less than the current discharge power setting, the current discharge power setting will be used as the target discharge power setting; or 04. When the actual output power is greater than or equal to the current discharge power setting value, the target discharge power setting value is determined based on the preset discharge power and the current discharge power setting value.

[0020] It's worth noting that energy storage power supplies refer to portable power devices with energy storage capabilities. An energy storage power supply includes at least two power interfaces for providing DC charging services to external devices. These power interfaces are the interfaces on the energy storage power supply used to connect external devices, including but not limited to Type-C interfaces, USB-A interfaces, and car charger interfaces. Each power interface has its own specifications; for example, the maximum nominal power of a Type-C interface can be up to 140W; USB-A interfaces are mostly used for low-power devices, with a nominal power typically between 15W and 30W; and car charger interfaces are compatible with in-vehicle electrical appliances, with a nominal power typically above 120W.

[0021] Actual output power refers to the power value transmitted by the power interface in real time when an external device is connected. Temperature refers to the real-time temperature value of the power interface during operation, which can be obtained by a temperature sensor located at or near the power interface.

[0022] Specification parameters refer to the inherent attribute parameters of the power interface, including at least the maximum nominal output power of the interface. These parameters do not change with usage time or environment. Real-time battery level refers to the current remaining battery capacity of the energy storage power supply, which can be expressed as State of Charge (SOC). As the battery capacity is consumed, the maximum discharge efficiency of the energy storage power supply will decrease. Therefore, it is necessary to adjust the discharge limit according to this parameter to prevent voltage drops or power outages due to insufficient battery capacity.

[0023] "At least two" refers to obtaining two, three, or all four parameters from the actual output power, temperature, specifications, and real-time power, depending on the product specifications. The specific selection method is determined by the product design of the energy storage power supply.

[0024] The preset discharge power refers to an upper limit value determined based on the acquired parameters, used to constrain the discharge power of the power interface. The current discharge power setting value refers to the discharge power value allowed to be used by the power interface at the current moment. The target discharge power setting value refers to the final and actually effective discharge power value determined after judgment, and the energy storage power supply controls the power interface to output power to external devices according to this value.

[0025] In one embodiment, the energy storage power supply includes a Type-C interface and a USB-A interface, with the Type-C interface nominally rated at 140W and the USB-A interface nominally rated at 15W.

[0026] At this time, the energy storage power supply is connected to two external devices. The actual output power of the Type-C interface is 20W and the temperature is 65℃; the actual output power of the USB-A interface is 10W and the temperature is 55℃; and the real-time power of the energy storage power supply is 30%. In this embodiment, all four parameters are selected for acquisition.

[0027] Next, based on the acquired parameters, the preset discharge power is determined. Simultaneously, the current discharge power setting of the Type-C interface is obtained as 140W. Since the actual output power of the Type-C interface (20W) is less than the current discharge power setting of 140W, the current discharge power setting of 140W is used as the target discharge power setting of the Type-C interface. The Type-C interface is then controlled to supply power to the external device at the target discharge power setting of 140W.

[0028] The current discharge power setting of the USB-A interface is 15W. Since the actual output power of the USB-A interface is 10W, which is less than the current discharge power setting of 15W, the current discharge power setting of 15W is used as the target discharge power setting of the USB-A interface. The USB-A interface is then controlled to supply power to the external device at the target discharge power setting of 15W.

[0029] In another embodiment, the external device in the above-described scenario is replaced with a laptop computer instead of a mobile phone. The actual output power of the Type-C interface increases to 100W, and the temperature rises to 75°C. Simultaneously, the real-time power level of the energy storage power supply decreases to 20%. Based on the acquired parameters, the preset discharge power is redefined, and this time the preset discharge power decreases to 60W. The current discharge power setting of the Type-C interface remains at 140W.

[0030] Since the actual output power of the Type-C interface is 100W, which is less than the current discharge power setting of 140W, the current discharge power setting of 140W will still be used as the target discharge power setting for the Type-C interface. However, since the preset discharge power has been reduced to 60W, the actual output power is constrained by the upper limit of 60W, and the actual charging power of the laptop is limited to within 60W.

[0031] Thus, this application determines the preset discharge power by obtaining at least two parameters from the actual output power, temperature, specification parameters, and real-time power of the power interface. When the actual output power is less than the current discharge power setting value, the current setting value is maintained to avoid unnecessary derating. When the actual output power is greater than or equal to the current discharge power setting value, a target value is determined based on the preset discharge power and the current setting value to achieve power limitation, thereby optimizing the user experience while ensuring safety.

[0032] Please see Figure 2 and Figure 3 In some implementations, step 02 includes: 021, Set the first preset power of the power interface based on the specification parameters; 022, Set the second preset power of the power interface based on the usage status; 023, The third preset power of the power interface is determined based on temperature; 024, Determine the fourth preset power of the power interface based on the real-time power of the energy storage power source; 025, the minimum value among the first preset power, the second preset power, the third preset power and the fourth preset power is taken as the preset discharge power.

[0033] It is worth noting that the usage status refers to whether the power interface is in single-port or multi-port use, and the corresponding upper limit of output power is different in different usage statuses. The minimum value refers to the smallest value selected from the first preset power, the second preset power, the third preset power, and the fourth preset power. Using this minimum value as the preset discharge power can ensure that the constraints of four dimensions—specification parameters, usage status, temperature, and real-time power of the energy storage power supply—are met simultaneously.

[0034] In one embodiment, the energy storage power supply includes a Type-C interface and a USB-A interface.

[0035] For the Type-C interface, the first preset power is set to 140W based on specifications. Given that both interfaces are currently in use, the second preset power is 100W. Based on the current temperature of 65℃, which has reached the derating temperature point, the third preset power is 80W. Based on the real-time battery level, the fourth preset power is determined to be 100W, with the current battery level at 30%. The minimum of the four preset power values, 80W, is taken as the preset discharge power for the Type-C interface.

[0036] For the USB-A interface, the first preset power is set to 15W based on specifications. The second preset power is set based on usage status; with both interfaces in use simultaneously, the second preset power for the USB-A interface is 10W. The third preset power is determined based on temperature; at the current temperature of 55℃, below the derating temperature point, the third preset power is 15W. The fourth preset power is determined based on real-time battery level; at 30%, the fourth preset power is 100W. The minimum of the four preset power values, 10W, is used as the preset discharge power for the USB-A interface.

[0037] In this way, each power interface independently determines its preset power based on four dimensions: specification parameters, usage status, temperature, and real-time power. The minimum value among the four is taken as the preset discharge of the interface, which can ensure that each interface works safely under its own constraints.

[0038] Please see Figure 4 In some implementations, step 021 includes: 0211, the output power of the power interface when the energy storage power supply is powered on is used as the first preset power.

[0039] It is worth noting that "power-on" refers to the initial moment when the energy storage power supply switches from a power-off state to a power-on state. At this time, the power interface has not yet been connected to external devices or has just been prepared, and its output power is configured to the maximum nominal output power in the specifications. The first preset power refers to the power setting value at this initial moment.

[0040] In one embodiment, see Figure 5 The energy storage power supply includes three Type-C ports, one USB-A port, and one car charger output port. According to the product specifications, the maximum nominal output power of the Type-C1 and 1xType-C2 ports is 140W, the maximum nominal output power of the 1xType-C3 port is 65W, the maximum nominal output power of the USB-A port is 15W, and the maximum nominal output power of the car charger output port is 120W. When the energy storage power supply is powered on, in this embodiment, the three Type-C ports, one USB-A port, and one car charger output port operate at their respective maximum nominal output power as the first preset power.

[0041] Thus, by using the output power of the power interface when the energy storage power supply is powered on as the first preset power, this value reflects the maximum discharge capacity of the power interface without any external constraints, providing a benchmark for subsequent power allocation.

[0042] Please see Figure 6 In some implementations, step 022 includes: 0221, Determine the current output mode of the power interface based on the usage status; 0222, use the maximum output power corresponding to the current output mode as the second preset power.

[0043] It is worth noting that the current output mode is a combination determined based on the actual usage status of each power interface, such as single-interface output mode, dual-interface output mode, and multi-interface output mode. Each output mode corresponds to a preset maximum output power value, which is stored in the energy storage power supply.

[0044] Please see Figure 7 In one embodiment, the energy storage power supply includes three Type-C interfaces, namely Type-C1, Type-C2, and Type-C3, a USB-A interface, and a car charger output port.

[0045] When both ports C1 and C2 are used simultaneously, the current output mode is C1+C2 simultaneous output mode, with a maximum output power of 140W for both ports. 140W is used as the second preset power for both ports.

[0046] When both ports C1 and C3 are used simultaneously, the current output mode is C1+C3 simultaneous output mode. The maximum output power corresponding to this mode is 140W for port C1 and 65W for port C3. 140W is set as the second preset power for port C1, and 65W is set as the second preset power for port C3.

[0047] When ports C1, C2, and C3 are used simultaneously, the current output mode is C1+C2+C3 simultaneous output mode. The maximum output power corresponding to this mode is 140W for port C1, 140W for port C2, and 65W for port C3. 140W is set as the second preset power for port C1, 140W for port C2, and 65W for port C3.

[0048] When ports C1, C2, and the car charger are used simultaneously, the current output mode is C1+C2+car charger simultaneous output mode. The maximum output power corresponding to this mode is 100W for port C1, 100W for port C2, and 120W for the car charger port. 100W is set as the second preset power for port C1, 100W for port C2, and 120W for the car charger port.

[0049] In this way, by determining the current output mode based on the usage status and using the maximum output power corresponding to that mode as the second preset power, the power limit of each interface can be reasonably limited when multiple interfaces are used at the same time, so as to avoid the total output power exceeding the carrying capacity of the energy storage power supply.

[0050] Please see Figure 8 In some implementations, step 0221 includes: 02211, Determine the usage status of each power interface based on its actual output power; 02212, Determine the output mode of the power interface based on the usage status of each power interface.

[0051] It is worth noting that the actual output power refers to the power value that the power interface outputs to the external device at the current moment, and the unit is watts.

[0052] In one embodiment, the energy storage power supply includes a Type-C interface (C1), a Type-C interface (C2), a USB-A interface, and a car charger interface.

[0053] The actual output power of port C1 is 20W, indicating it is in use. The actual output power of port C2 is 0W, indicating it is not in use. The actual output power of port USBA is 10W, indicating it is in use. The actual output power of the car charger port is 0W, indicating it is not in use.

[0054] Based on the usage status of each power interface, the current output mode is determined to be simultaneous output mode of C1 port + USBA port.

[0055] In this way, by determining the usage status of each interface based on the actual output power, and then determining the current output mode based on the usage status of each interface, it is possible to accurately identify which interfaces are in use and their combination, providing a basis for subsequently determining the maximum output power in that mode.

[0056] Please see Figure 9 In some embodiments, step 02211 includes: 022111, if the actual output power of the power interface is greater than 0W, the power interface is determined to be in operation. 022112 indicates that the power interface is in an unloaded state when the actual output power of the power interface is 0W.

[0057] It's worth noting that the "operating" status indicates that the power interface is currently supplying power to an external device. The "no-load" status indicates that the power interface is not currently connected to an external device, or that an external device is connected but not charging.

[0058] In one embodiment, the energy storage power supply includes a Type-C interface. This interface is currently connected to a mobile phone, and its actual output power is 20W. Since 20W is greater than 0W, the interface is determined to be in an operational state.

[0059] In another embodiment, the Type-C interface is not connected to any external device, and the actual output power is 0W, so the interface is determined to be in an unloaded state.

[0060] In another embodiment, the Type-C interface is connected to a fully charged mobile phone. The mobile phone no longer draws current, and the actual output power is 0W, so the interface is determined to be in an unloaded state.

[0061] Thus, the usage status of the interface is determined by whether the real-time output power is greater than 0. The determination method is simple and direct, without the need for complex detection logic, and can quickly and accurately identify which interfaces are in use.

[0062] Please see Figure 10 In some implementations, step 023 includes: 0231, the third preset power is the maximum output power of the power interface at the specified temperature.

[0063] It's worth noting that the power interface generates heat during operation, causing its temperature to rise. When the temperature reaches the preset derating temperature, the maximum output power of the power interface will decrease accordingly. The correlation between temperature and maximum output power is pre-stored in the energy storage power supply, for example, through a temperature-power derating table or derating curve. The temperature of the power interface can be monitored in real time using a negative temperature coefficient thermistor (NTC).

[0064] Please see Figure 11 In one embodiment, the energy storage power supply includes a Type-C interface, namely C1 port, which has a pre-stored temperature-power derating strategy as follows: when the NTC temperature is ≤95°C, the power of C1 port is ≤140W; when 95°C < NTC temperature ≤105°C, the power of C1 port is ≤100W; and when 105°C < NTC temperature ≤115°C, the power of C1 port is ≤65W.

[0065] The current real-time NTC temperature of port C1 is 98℃, which falls within the 95℃ to 105℃ range, corresponding to a maximum output power of 100W. 100W is used as the third preset power for port C1.

[0066] If the temperature of port C1 rises to 108℃, falling within the range of 105℃ to 115℃, the corresponding maximum output power is 65W, and 65W is used as the third preset power. If the temperature of port C1 drops to 90℃, it will return to 140W.

[0067] In another embodiment, the energy storage power supply includes a Type-C interface, namely the C2 port. The pre-stored temperature-power derating strategy of this interface is as follows: when the NTC temperature is ≤87°C, the C2 port power is ≤100W; when 87°C < NTC temperature ≤101°C, the C2 port power is ≤65W; and when 101°C < NTC temperature ≤115°C, the C2 port power is ≤45W.

[0068] The current real-time NTC temperature of port C2 is 90℃, falling within the range of 87℃ to 101℃, corresponding to a maximum output power of 65W. 65W is set as the third preset power for port C2.

[0069] If the temperature of port C2 rises to 105℃, which is in the range of 101℃ to 115℃, the corresponding maximum output power is 45W. Then, 45W is used as the third preset power.

[0070] In this way, by using the maximum output power of the power interface at the current temperature as the third preset power, the power limit can be reduced in time when the temperature rises, preventing the interface from overheating and being damaged, and ensuring the safe use of the energy storage power supply.

[0071] Please see Figure 12 In some implementations, step 04 includes: 041, Compare the preset discharge power with the current discharge power setting; 042, if the current discharge power setting is greater than or equal to the preset discharge power, the preset discharge power is used as the target discharge power setting; or 043. If the current discharge power setting is less than the preset discharge power, the current discharge power setting will be used as the target discharge power setting.

[0072] It is worth noting that this embodiment compares the preset discharge power and the current discharge power setting value, and takes the smaller of the two as the target discharge power setting value. When the current discharge power setting value is large, it means that the current setting value exceeds the safety limit and needs to be adjusted down to the preset discharge power; when the current discharge power setting value is small, it means that the current setting value is within the safety range and no adjustment is needed.

[0073] In one embodiment, the energy storage power supply includes a Type-C interface. The preset discharge power is 80W, and the current discharge power setting is 100W. Since the current discharge power setting of 100W is greater than the preset discharge power of 80W, the preset discharge power of 80W is used as the target discharge power setting. The Type-C interface is controlled to supply power to external devices at 80W.

[0074] In another embodiment, the preset discharge power is 80W, and the current discharge power setting is 60W. Since the current discharge power setting of 60W is less than the preset discharge power of 80W, the current discharge power setting of 60W is used as the target discharge power setting. The Type-C interface is controlled to supply power to the external device at 60W.

[0075] In another embodiment, the preset discharge power is 80W, and the current discharge power setting is also 80W. Since both are equal, the condition that the current discharge power setting is greater than or equal to the preset discharge power is met, and the preset discharge power of 80W is used as the target discharge power setting.

[0076] In this way, by comparing the preset discharge power and the current discharge power setting, the smaller of the two is taken as the target discharge power setting, ensuring that the actual output power of the power interface never exceeds the safety limit, while avoiding unnecessary power adjustments when derating is not required.

[0077] This application proposes an energy storage power source, including a controller for executing a power distribution control method as described in any of the above embodiments.

[0078] It is worth noting that the controller refers to the microcontroller or management chip inside the energy storage power supply, which is used to acquire parameters of each power interface, execute logic judgments, and control power output.

[0079] Thus, by implementing the above-mentioned discharge power distribution control method through the built-in controller of the energy storage power supply, the discharge power of each interface can be dynamically adjusted according to the actual usage, temperature, specifications and its own power, thereby optimizing the user charging experience while ensuring safety.

[0080] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
