[0022] Please refer to Figure 1 , Figure 1 is an application scenario of a control method of an energy storage power supply provided by an embodiment of the present application. The application scenario provided by the present application includes an energy storage power supply 100 and an electronic device 200.

[0031] The battery is the energy core of the energy storage power supply and is a component of the energy storage power supply.

[0032] The main control board is the control core of the energy storage power supply, and the wake-up, shutdown, charging judgment, and power consumption management of the system are controlled by the main control board.

[0033] The battery management system (BMS) is an electronic system used to monitor, protect, optimize, and manage batteries (such as lithium batteries, lead-acid batteries, etc.). Its core function is to ensure that the battery works efficiently within a safe range, prolongs the service life, and provides stable power output for the device.

[0039] The energy storage power supply 100 can communicate with the electronic device 200 to implement the control method of the present application in cooperation with the electronic device 200.

[0040] Optionally, the electronic device 200 includes at least one of a terminal and a server.

[0041] The terminal can include, but is not limited to, a smartphone (such as an Android phone, an IOS phone, etc.), a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a portable personal computer, a mobile internet device (MID), a smart voice interaction device, a smart home appliance, a vehicle-mounted terminal, an aircraft, a wearable device, etc., and the embodiments of the present application do not limit this.

[0043] The control method of the energy storage power supply can be realized by the energy storage power supply alone or in cooperation with the electronic device, and the present application does not limit the same.

[0044] Based on the above introduction of the related scenarios, the embodiments of the present application provide a control method of an energy storage power supply, which will be described in detail as follows.

[0045] Please refer to Figure 2 The control method of the energy storage power supply provided by the embodiments of the present application is realized by steps 011 to 013, which will be described in detail as follows.

[0046] Step 011: In the case where it is detected that the charging interface of the energy storage power supply is connected to an external power supply, a charging identification operation is performed to obtain an identification result, and the identification result includes whether charging is performed.

[0047] In an optional embodiment, the main control board is connected to the charging interface, and in the case where the external power supply is connected, the voltage of the charging interface changes, and the main control board determines whether the external power supply is connected by detecting the voltage of the charging interface.

[0048] The charging identification operation is an operation for identifying whether the energy storage power supply is actually charging. In an optional embodiment, the charging identification operation includes:

[0049] detecting whether the voltage of the external power supply is greater than a preset threshold value;

[0050] If yes, it indicates that the external power supply is normally powered, and at this time it is necessary to determine whether the energy storage power supply is actually charging. The energy storage power supply can be determined whether to meet the following conditions: if no, the external power supply is not normally powered, and the charging identification operation is not needed.

[0051] (1) Continuously detecting whether the current of the charging port of the battery is greater than a first current threshold value within a first preset time period.

[0052] It can be understood that when the battery is charging, the charging port of the battery is continuously inputting current. If the input current is too small or even 0, it means that the battery is not actually charging. Therefore, by detecting whether the current of the charging port of the battery is greater than the first current threshold, it can accurately detect whether the battery is actually charging, and ensure that the first preset time (such as 30 seconds (s), 60 s, etc.) detects that the charging current is greater than the first current threshold, which can further improve the accuracy of charging identification.

[0053] (2) whether the voltage of the battery continues to rise within the second preset time.

[0054] It can be understood that the voltage of the battery will increase with the increase of the power, so that whether the voltage of the battery increases with the increase of the charging time (such as whether the voltage of the battery continues to rise within the second preset time) can also accurately detect whether the battery is charging.

[0055] (3) whether the charging switch of the energy storage power supply is closed.

[0056] It can be understood that when charging, the BMS will control the charging switch to be closed. After the BMS issues a control instruction to control the charging switch to be closed, the state information of the charging switch will be fed back to the main control board, so as to facilitate the main control board to assist in decision-making whether the energy storage power supply is charging.

[0057] The main control board can improve the accuracy of charging identification by judging the above conditions (2)-(4) in combination with the voltage detection of the external power supply, and avoid the situation of "false charging".

[0058] If any of the conditions (2)-(4) is not met, it can be determined that the energy storage power supply is in the "false charging" state, so as to normally enter the subsequent shutdown determination process.

[0059] In an optional embodiment, the battery management system is used to detect the current of the charging port of the battery, the voltage of the battery, and control the charging switch to be turned on or turned off, and feed back the current of the charging port, the voltage of the battery, and the current state of the charging switch to the main control board.

[0060] It can be understood that the battery management system can detect the current of the charging port of the battery, the voltage of the battery, and control the charging switch to be turned on or turned off in real time, and feed back the current of the charging port, the voltage of the battery, and the current state of the charging switch to the main control board, so as to assist the main control board to realize the charging identification operation.

[0061] Step 012: If any of the above conditions is not met, enter the shutdown determination process, which is used to control the energy storage power supply to shut down when the energy storage power supply meets the preset shutdown condition.

[0062] Specifically, after determining the identification result through the charging identification operation, if the identification result is that the energy storage power supply is not charging (i.e., the voltage of the external power supply is greater than the preset threshold, but any one of conditions (2)-(4) is not met), that is, although the energy storage power supply is connected to the external power supply, the charging switch may not be closed due to low temperature or the like, and the energy storage power supply is in a "false charging" state, and the battery is actually not charged. Therefore, at this time, the shutdown determination process can be entered, and whether the energy storage power supply meets the preset shutdown condition is determined to control the energy storage power supply to shut down in time to avoid unnecessary power consumption of the energy storage power supply.

[0063] For example, the preset condition can be that the time length of the energy storage power supply in the standby state is greater than a third preset time length, and the discharge current of the energy storage power supply is less than a second current threshold when the energy storage power supply is in the standby state.

[0064] That is, the energy storage power supply is in the standby state when it is not charging and not discharging to the load, and if the standby state lasts for too long, unnecessary power consumption will occur. Therefore, when the time length of the standby state is greater than the third preset time length, the energy storage power supply can be controlled to shut down. The third preset time length is an empirical value, such as 5 minutes, 10 minutes, etc.

[0065] When the identification result is that the energy storage power supply is charging, the energy storage power supply can be maintained in the current operating condition to ensure normal charging.

[0066] The control method of the energy storage power supply of the present application does not directly determine that the energy storage power supply is charging when the charging interface of the energy storage power supply is connected to the external power supply, but further performs a charging identification operation. The voltage of the external power supply is first detected to determine whether it is greater than a preset threshold. When the voltage of the external power supply is greater than the preset threshold, it is determined that the external power supply is supplying power, and then the battery current, the battery voltage, and the closing condition of the charging switch are determined to accurately determine whether the energy storage power supply is charging.

[0067] Through accurate identification of the "false charging" state of the energy storage power supply, the energy storage power supply can normally enter the shutdown determination process when the energy storage power supply is not charging (i.e., any one of the above conditions is not met), such as shutting down when the standby time reaches a certain length, so that the energy storage power supply shuts down normally and avoids unnecessary power consumption, which is beneficial to avoid the risk of power supply due to power consumption.

[0068] Please refer to Figure 3 In some embodiments, the control method further comprises:

[0069] Step 013: In the case where the main control board is awakened, the ambient temperature is obtained.

[0070] Step 014: If the ambient temperature is lower than the first temperature threshold, and the ambient temperature does not rise above the first temperature threshold within the first preset time length, the energy storage power supply is controlled to shut down.

[0071] The ambient temperature refers to the temperature collected by the temperature sensor of the inverter. Through the temperature sensor of the inverter, the ambient temperature of the environment where the energy storage power supply is located can be accurately collected.

[0072] It can be understood that the energy storage power supply may not be able to charge normally in an extremely cold environment, and if there is no effective load running at this time (i.e., the discharge current of the energy storage power supply is less than a second current threshold (such as 10 mA, 20 mA, etc.)), if the energy storage power supply continues to work at this time, unnecessary power consumption will be caused.

[0073] Therefore, by detecting the ambient temperature, it is determined whether the ambient temperature is lower than the first temperature threshold (such as below -5 degrees Celsius, below -10 degrees Celsius, etc., which is an empirical value), to determine whether it is in an extremely cold environment.

[0074] In the case where it is determined that the ambient temperature is lower than the first temperature threshold, it is determined that the energy storage power supply is working in an extremely cold environment, and at this time the energy storage power supply can be forced to shut down, thereby avoiding unnecessary power consumption and improving the long-time anti-feed power capability of the energy storage power supply in an extremely cold environment.

[0075] In addition, in order to avoid misjudgment caused by fluctuations in the ambient temperature, the change of the ambient temperature within the first preset time length can be continuously monitored when the ambient temperature is lower than the first temperature threshold, and if the ambient temperature does not rise above the first temperature threshold, it can be determined that the energy storage power supply is indeed in an extremely cold environment. In this way, the accuracy of low-temperature detection of the energy storage power supply can be further improved.

[0076] In an optional embodiment, in order to avoid the wake-up power consumption in an extremely cold environment, when waking up components other than the main control board (such as BMS, inverter, etc.), it can be determined whether the energy storage power supply is in an extremely cold environment, and if it is in an extremely cold environment, these components do not need to be woken up, but are directly shut down, thereby reducing the wake-up power consumption of the energy storage power supply.

[0077] In an optional embodiment, the energy storage power supply further comprises a real-time clock module, and the main control board is woken up in the case where a power-on instruction is received or a wake-up instruction of the real-time clock module is received.

[0078] Generally, the energy storage power supply is provided with a power-on button, and the power-on button can send a power-on instruction to wake up the main control board and realize the control of the energy storage power supply; or the energy storage power supply is provided with a low-power running real-time clock module, and the real-time clock module can trigger the wake-up at regular intervals and send a wake-up instruction to wake up the main control board.

[0079] In an alternative embodiment, the real-time clock module issues a wake-up instruction to wake up the energy storage power supply within a preset wake-up window.

[0080] For example, the wake-up window can be a daily sunlight period (e.g., around 12 noon), during which the ambient temperature is generally high and will not trigger a low-temperature forced shutdown, and the wake-up instruction can be issued to wake up the energy storage power supply to normally perform charging.

[0081] In an alternative embodiment, after the energy storage power supply wakes up each time, the local weather information (e.g., sunrise time, sunset time, temperature at different times, etc.) can be obtained through wireless communication with the server, and the wake-up window can be set accordingly, for example, the sunlight period is the period between sunrise and sunset.

[0082] Specifically, within the preset wake-up window, the real-time clock module first issues a first wake-up instruction to the inverter to wake up the inverter. The real-time clock module wakes up the inverter to perform low-power operation, and the inverter can independently obtain the ambient temperature. If the collected ambient temperature is greater than a third temperature threshold, the real-time clock module issues a second wake-up instruction to the main control board to wake up the main control board. In this way, the real-time clock module in low-power operation and the inverter can achieve simple detection of extremely cold environments, and in the case of detecting that the energy storage power supply is in an extremely cold environment, the main control board and other components are avoided from being woken up, thereby avoiding unnecessary wake-up power consumption.

[0083] In an alternative embodiment, the wake-up window is determined based on a preset wake-up period and a wake-up frequency in each wake-up period, and the wake-up frequency is determined based on the sleep power consumption of the energy storage power supply, the sunlight time in the wake-up period, the single wake-up duration, and the wake-up power consumption. The wake-up frequency is positively correlated with the sleep power consumption and the sunlight time in the wake-up period, respectively, and the wake-up frequency is negatively correlated with the single wake-up duration and the wake-up power consumption, respectively.

[0084] For example, the wake-up period can be set by the user, such as daily, weekly, etc. In each wake-up period, the wake-up frequency can also be set. For example, if the energy storage power supply wakes up 3 times a day, the wake-up window can be set at 3 different time points in a day.

[0085] Alternatively, the wake-up frequency can also be adaptively adjusted based on the working conditions of the energy storage power supply. For example, the wake-up frequency is determined based on the sleep power consumption of the energy storage power supply, the sunlight time in the wake-up period, the single wake-up duration, and the wake-up power consumption, wherein the wake-up frequency is positively correlated with the sleep power consumption and the sunlight time in the wake-up period, respectively, and the wake-up frequency is negatively correlated with the single wake-up duration and the wake-up power consumption, respectively.

[0086] For example, the number of wake-ups is determined based on the following formula:

[0087]

[0088] where I sleep is the sleep power consumption, T day is the sunshine time, T wake is the single wake-up duration, I wake is the wake-up power consumption.

[0089] In an optional embodiment, the temperature correction coefficient corresponding to the first target temperature interval in which the ambient temperature is located can be determined based on the first target temperature interval, and the first target temperature interval is any first preset temperature interval, and each first preset temperature interval has a corresponding temperature correction coefficient; the corresponding power correction coefficient is determined based on the remaining power, and the power correction coefficient and the remaining power are in a positive correlation relationship; the number of wake-ups is adjusted based on the temperature correction coefficient and the power correction coefficient.

[0090] Specifically, a plurality of first preset temperature intervals can be divided, such as less than -20 degrees Celsius (℃), [-20℃, -10℃], greater than -10℃, and each first preset temperature interval is provided with a corresponding temperature correction coefficient. It can be understood that the higher the temperature, the more the number of wake-ups, that is, the larger the temperature correction coefficient.

[0091] Then, the first target temperature interval in which the ambient temperature is located is determined, so as to determine the corresponding temperature correction coefficient.

[0092] Then, the remaining power of the energy storage power supply is determined to determine the corresponding power correction coefficient, and the more the remaining power, the more the number of wake-ups, and the larger the power correction coefficient.

[0093] Finally, the number of wake-ups is adjusted based on the temperature correction coefficient and the power correction coefficient, so as to obtain a more accurate number of wake-ups.

[0094] For example, the actual number of wake-ups can be calculated by the following formula:

[0095] η real = η opt × K temp × K SOC

[0096]

[0097]

[0098] where η real is the actual number of wake-ups, η opt is the number of wake-ups before adjustment, and Ktemp K is a temperature correction coefficient, T is an ambient temperature, SOC is a remaining power. SOC K is a temperature correction coefficient, T is an ambient temperature, SOC is a remaining power.

[0099] In one example, different wakeup strategies can be set in different temperature intervals and power intervals.

[0100] The following table

[0101] Please

[0102] Referring to Figure 4 In some embodiments, the method further comprises:

[0103] Step 015: If the ambient temperature is lower than a first temperature threshold, and the ambient temperature rises above the first temperature threshold within a first preset time interval, the battery management system is woken up to obtain the temperature of the battery.

[0104] Step 016: If the temperature of the battery is lower than a second temperature threshold, and the temperature of the battery does not rise above the second temperature threshold within a second preset time interval, the energy storage power supply is shut down.

[0105] Step 017: If the temperature of the battery is lower than a second temperature threshold, and the temperature of the battery rises above the second temperature threshold within a second preset time interval, the energy storage power supply is allowed to charge.

[0106] Specifically, if the ambient temperature is lower than a first temperature threshold, and the ambient temperature rises above the first temperature threshold within a first preset time interval, it can be determined that the environment at this time is not likely to be an extremely cold environment, and therefore the battery management system can be woken up at this time to obtain the temperature of the battery (such as the average temperature of each cell) for more accurate temperature detection.

[0107] If the temperature of the battery is lower than a second temperature threshold, and the temperature of the battery does not rise above the second temperature threshold within a second preset time interval, it can be accurately determined that the battery is in an extremely cold environment, and at this time the energy storage power supply can be shut down to achieve low-temperature protection.

[0108] If the temperature of the battery is lower than a second temperature threshold, and the temperature of the battery rises above the second temperature threshold within a second preset time interval, it can be determined that the battery is not in an extremely cold environment, and at this time the energy storage power supply can be allowed to charge normally.

[0109] In this way, the ambient temperature collected by the temperature sensor of the inverter and the battery temperature collected by the BMS can be combined to achieve low-temperature detection of the energy storage power supply, achieve low-temperature protection of the energy storage power supply, and reduce the problem of false charging of the energy storage power supply due to the inability of the charging switch to close under low-temperature conditions.
