[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The battery charging method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The energy storage device includes a battery management system 101, an auxiliary power supply 102, an integrated energy storage battery 103 and an energy storage converter 104; the energy storage converter 104 is used to supplement the energy storage battery 103 with an external power grid under the control of the battery management system 101; the auxiliary power supply 102 is used to output a wake-up signal to the battery management system 101 after connecting to the external power grid. The battery management system 101 is respectively connected to the auxiliary power supply 102 and the integrated energy storage battery 103 and the energy storage converter 104.

[0046] Among them, the battery management system 101 is the core control unit of the energy storage device, which is responsible for real-time monitoring and management of the operating status of the energy storage battery 103, which may include parameters such as the voltage, current, temperature and health status of the energy storage battery 103. The battery management system 101 collects data such as the voltage, current, temperature and other data of the energy storage battery 103 to evaluate the health status and remaining power of the energy storage battery 103 in real time. When the energy storage battery 103 needs to be charged, the battery management system 101 will control the energy storage inverter 104 to start the corresponding power replenishment process to charge the energy storage battery 103.

[0047] When the energy storage device is connected to the external power grid, the auxiliary power supply 102 will first start and supply power to the battery management system 101. The power supply signal output by the auxiliary power supply 102 serves as a wake-up signal, enabling the battery management system 101 to quickly enter the working state after the energy storage device is powered on, and begin to monitor and manage the various operating parameters of the energy storage battery 103.

[0048] The energy storage battery 103 is the main medium for storing electrical energy in the energy storage device. The energy storage battery 103 is usually composed of multiple battery cells, which can be connected in series or in parallel according to specific needs to provide the required voltage and capacity. The main task of the energy storage battery 103 is to store electrical energy generated by the external power grid or renewable energy, and release the electrical energy when needed to meet electricity demand or support the stable operation of the power grid.

[0049] The energy storage converter 104 is the core device for power conversion, responsible for converting the AC power from the external power grid into DC power for charging the energy storage battery 103, and adjusting the charging voltage and current according to the instructions of the battery management system 101 to achieve the best charging effect. At the same time, the energy storage converter 104 also has bidirectional power conversion capability. When the battery is discharged, it can convert the DC power in the energy storage battery 103 into AC power and transmit it to the external power grid to support the load regulation of the external power grid or provide backup power.

[0050] In an exemplary embodiment, Figure 2 As shown, a battery charging method is provided, which is applied to Figure 1 The battery management system of the energy storage device in the embodiment is described as an example, and includes the following steps 201 to 202. Among them:

[0051] Step 201: After receiving the wake-up signal, if it is determined that the current working mode of the energy storage device is the transportation mode, the access signal of the energy storage device is detected.

[0052] The wake-up signal is a power supply signal transmitted by the auxiliary power supply to the battery management system when the auxiliary power supply is connected to the external power grid.

[0053] In the embodiment of the present application, when the energy storage device is connected to the external power grid, the auxiliary power supply will start and supply power to the battery management system, and the power supply signal output by the auxiliary voltage is the wake-up signal. After receiving the wake-up signal, the battery management system can determine the current working mode by reading the pre-stored or set configuration parameters.

[0054] If it is determined that the current working mode of the energy storage device is the transport mode, the access signal of the energy storage device is detected.

[0055] Step 202: When it is determined that the access signal is an AC signal, control the energy storage converter to charge the energy storage battery to a preset state of charge.

[0056] In the embodiment of the present application, when it is determined that the access signal is an AC signal, the battery management system first confirms the accessed AC signal and determines whether the voltage, current, frequency and other parameters of the AC signal meet the charging requirements of the energy storage device. If the detected AC signal parameters do not meet the requirements, the battery management system may not process the access signal.

[0057] After confirming that the access signal is normal, the battery management system will conduct a comprehensive test on the current state of the energy storage battery, including the state of charge, temperature, health status, etc. of the energy storage battery, to determine whether the energy storage battery is suitable for charging. If the energy storage battery is not suitable for charging, the battery management system will take corresponding protective measures, such as adjusting the charging current or delaying charging.

[0058] When the energy storage battery is in a state suitable for charging, the battery management system can select a suitable charging strategy based on the current state of the energy storage battery and the preset state of charge to control the energy storage converter to charge the energy storage battery to the preset state of charge. The charging strategy may include constant voltage charging, constant current charging or multi-stage charging to optimize the charging speed and battery life.

[0059] It should be noted that during the charging process, the battery management system continuously monitors the voltage, current, temperature and other parameters of the energy storage battery. If an abnormal situation is detected, such as excessive temperature or voltage outside the safe range, the battery management system will immediately adjust the charging parameters or terminate charging to prevent damage to the energy storage battery.

[0060] When the state of charge of the energy storage battery reaches a preset state of charge, the battery management system sends a stop signal to the energy storage inverter to terminate the charging operation.

[0061] In the above-mentioned battery charging method, after receiving the wake-up signal, if it is determined that the current working mode of the energy storage device is the transportation mode, the access signal of the energy storage device is detected; when it is determined that the access signal is an AC signal, the energy storage inverter is controlled to charge the energy storage battery to a preset charge state; compared with the method of charging the energy storage battery by an additional charging device in the traditional technology, the embodiment of the present application integrates the energy storage battery and the energy storage inverter into one, and can realize automatic charging without additional charging equipment, which can effectively reduce the charging cost. In addition, the integrated energy storage battery and energy storage inverter can reduce the connection complexity and configuration requirements between devices, which reduces the cost of connection between devices and reduces the time and labor cost of installation and maintenance. Finally, by charging according to the working mode and access signal after receiving the wake-up signal, the energy storage device can optimize the charging operation and reduce the cost. This strategy not only improves the efficiency of charging, but also effectively reduces unnecessary power consumption and power costs.

[0062] In an exemplary embodiment, Figure 3 As shown, in the above embodiment, “controlling the energy storage converter to charge the energy storage battery to a preset state of charge” may include the following steps:

[0063] Step 301: Send a charging instruction to the energy storage converter.

[0064] The charging instruction is used to instruct the energy storage converter to convert the AC signal into a DC signal, and use the DC signal to charge the energy storage battery.

[0065] In the embodiment of the present application, the battery management system sends a charging instruction to the energy storage converter. After receiving the charging instruction, the energy storage converter converts the AC power input from the external power grid into DC power, and uses the DC power to charge the energy storage battery.

[0066] Step 302: until it is detected that the current state of charge of the energy storage battery is greater than or equal to the preset state of charge, a stop instruction is sent to the energy storage converter.

[0067] The stop instruction is used to instruct the energy storage converter to stop charging the energy storage battery.

[0068] In the embodiment of the present application, the battery management system detects the state of charge of the energy storage battery in real time and compares it with the preset state of charge. When it is detected that the current state of charge of the energy storage battery is less than the preset state of charge, the energy storage battery is continuously charged. When it is detected that the current state of charge of the energy storage battery is greater than or equal to the preset state of charge, the battery management system sends a stop instruction to the energy storage converter.

[0069] After receiving the stop command, the energy storage converter stops outputting the DC signal, and the charging process ends. The battery management system checks the status of the energy storage battery again to ensure that the energy storage battery has reached the preset state of charge and confirms that there are no abnormalities in the entire charging process.

[0070] It should be noted that after charging is completed, the battery management system will record the data of the entire charging process, including charging time, power changes and other information.

[0071] In the above embodiment, the battery management system automatically stops charging when it detects that the charge state of the energy storage battery reaches or exceeds the preset charge state, which can reduce the occurrence of overcharging. This not only protects the energy storage battery, but also reduces unnecessary energy consumption and reduces electricity costs.

[0072] In an exemplary embodiment, the following steps may also be included:

[0073] When the energy storage device meets the low power consumption triggering condition, the energy storage device is controlled to enter the low power consumption mode.

[0074] Among them, the low power consumption triggering conditions include one or more of the following: the battery management system does not receive a wake-up signal, the access signal is not an AC signal, and the energy storage device is disconnected from the external power grid.

[0075] In the embodiment of the present application, the battery management system detects whether the low power consumption trigger condition is met. If it is detected that the energy storage device is not connected to the external power grid and the battery management system does not receive the wake-up signal, it is determined that the energy storage device meets the low power consumption trigger condition; if the battery management system receives the wake-up signal but detects that the access signal is not an AC signal, it is determined that the energy storage device meets the low power consumption trigger condition; if after charging the energy storage battery, it is detected that the energy storage device is disconnected from the external power grid, it is determined that the energy storage device meets the low power consumption trigger condition.

[0076] When confirming that the energy storage device meets the low-power trigger conditions, the battery management system controls the energy storage device to enter low power consumption, that is, the battery management system adjusts the settings of related components to reduce power consumption, such as shutting down unnecessary functions and reducing processor frequency.

[0077] The battery management system confirms that all components have successfully entered low power consumption and continues to monitor the device status to ensure that it operates normally at low power and can quickly return to normal mode when needed.

[0078] In the above embodiment, when the battery management system does not receive a wake-up signal, the access signal is not an AC signal, or the energy storage device is disconnected from the external power grid, the battery management system enters a low power consumption mode. In this way, the battery management system minimizes the energy consumed when it is not necessary to operate, which helps to reduce overall energy consumption and thus reduce operating costs.

[0079] In an exemplary embodiment, Figure 4 As shown, the above method also includes:

[0080] Step 401, obtaining mode configuration information; the mode configuration information includes configuration information of the low power mode and configuration information of the transport mode.

[0081] In the embodiment of the present application, the battery management system reads the mode configuration information from its storage medium (such as memory or configuration file). Then, the battery management system parses the read mode configuration information and extracts the specific configuration data of the low power mode and the transport mode, such as voltage, current limit, power consumption requirements, etc.

[0082] Step 402: configure the working mode of the energy storage device according to the mode configuration information.

[0083] In an embodiment of the present application, the battery management system parses the mode configuration information and determines the operating mode to be configured according to the current state and requirements of the energy storage device.

[0084] In some embodiments, first, the battery management system reads the mode configuration information from the storage medium, then parses the mode configuration information, checks whether the information format of the mode configuration information is correct, and extracts key configuration parameters of the transport mode, such as voltage, current limit, power consumption requirement, and temperature range.

[0085] The battery management system then verifies that the configuration is valid and performs the necessary tests to confirm that the device is operating normally in the expected mode.

[0086] In the above embodiments, by acquiring different mode configuration information (such as low power mode and transportation mode), the battery management system can flexibly switch the working mode according to actual needs, which enables the energy storage device to adapt to different application scenarios and operating conditions, significantly improving flexibility and adaptability.

[0087] In an exemplary embodiment, the method further includes:

[0088] Receive a wake-up signal sent by the auxiliary power supply; the wake-up signal is triggered after the auxiliary power supply is connected to the external power grid.

[0089] In an embodiment of the present application, first, the battery management system checks whether the auxiliary power supply is successfully connected to the external power grid. When the auxiliary power supply is connected to the external power grid, a wake-up signal is generated, which can be a change in the power supply voltage or a specific pulse signal. The battery management system receives the wake-up signal sent by the auxiliary power supply.

[0090] In the above embodiment, after the wake-up signal is triggered, the battery management system can quickly recover from the low power consumption state. This rapid response capability enables the energy storage device to respond to external power demand more promptly.

[0091] In an exemplary embodiment, the method further includes:

[0092] When it is determined that the energy storage battery is charged to a preset state of charge, a prompt message indicating that the charging is completed is output.

[0093] Among them, the prompt information is used to notify users or energy storage system stakeholders about a certain operation status or event. In the energy storage system, the prompt information of charging completion usually includes the following:

[0094] (1) Charging status confirmation: clearly indicates that the charging process has been successfully completed. For example: "Charging completed" or "Battery is fully charged."

[0095] (2) Current state of charge: Provides the actual state of charge when charging is completed, for example: "The current state of charge is 90%."

[0096] (3) Timestamp: Displays the timestamp of charging completion for recording and tracking purposes. For example: "Charging completion time: 14:30, August 19, 2024".

[0097] In the embodiment of the present application, when it is determined that the energy storage battery is charged to a preset state of charge, the battery management system outputs a prompt message indicating that the charging is completed. The way of outputting the prompt message may include: lighting a prompt light, playing a prompt sound, displaying a prompt text or a prompt mark on the display screen.

[0098] It should be noted that the output method of the prompt information is not limited to the above examples and can be set according to actual conditions.

[0099] In the above embodiment, by outputting a prompt message after charging is completed, the user can promptly know that the energy storage battery has been charged to a preset state of charge. This real-time feedback allows the user to intuitively know the charging status, greatly improving the user experience and the operational convenience of the energy storage system.

[0100] In an exemplary embodiment, a battery charging method is provided, which is described by taking the method applied to the battery management system of the energy storage device in the above embodiment as an example, and may include the following steps:

[0101] Step 1, obtaining mode configuration information; the mode configuration information includes configuration information of the low power mode and configuration information of the transport mode.

[0102] Step 2: configure the working mode of the energy storage device according to the mode configuration information.

[0103] Step 3, receiving a wake-up signal sent by the auxiliary power supply; the wake-up signal is triggered after the auxiliary power supply is connected to the external power grid.

[0104] Step 4: After receiving the wake-up signal, if it is determined that the current working mode of the energy storage device is the transportation mode, the access signal of the energy storage device is detected.

[0105] Step 5: When it is determined that the access signal is an AC signal, a charging instruction is sent to the energy storage inverter; the charging instruction is used to instruct the energy storage inverter to convert the AC signal into a DC signal and use the DC signal to charge the energy storage battery.

[0106] Step 6: until it is detected that the current state of charge of the energy storage battery is greater than or equal to the preset state of charge, a stop instruction is sent to the energy storage converter; the stop instruction is used to instruct the energy storage converter to stop charging the energy storage battery.

[0107] Step 7: When it is determined that the energy storage battery is charged to a preset state of charge, a prompt message indicating that the charging is completed is output.

[0108] Step 8, when the energy storage device meets the low power consumption triggering condition, control the energy storage device to enter the low power consumption mode; wherein the low power consumption triggering condition includes one or more of the battery management system not receiving the wake-up signal, the access signal is not an AC signal, and the energy storage device is disconnected from the external power grid.

[0109] In the above embodiment, after receiving the wake-up signal, if it is determined that the current working mode of the energy storage device is the transport mode, the access signal of the energy storage device is detected; when it is determined that the access signal is an AC signal, the energy storage converter is controlled to charge the energy storage battery to a preset state of charge; compared with the method of replenishing the energy storage battery by an additional power replenishment device in the traditional technology, the embodiment of the present application integrates the energy storage battery and the energy storage converter, so that no additional power replenishment device is required, which effectively reduces the cost of power replenishment. In addition, the integrated energy storage battery and energy storage converter can reduce the connection complexity and configuration requirements between devices, which reduces the cost of connection between devices and reduces the time and labor cost of installation and maintenance. Moreover, compared with the method of using EMS to control PCS power replenishment in the traditional technology, the embodiment of the present application sets the power replenishment logic in the BMS, and the BMS controls the PCS power replenishment instead, that is, the BMS automatically controls the PCS to charge the energy storage battery according to the working mode and the access signal after receiving the wake-up signal, so as to optimize the charging operation and reduce the cost. This strategy not only improves the efficiency of charging, but also effectively reduces unnecessary power consumption and power costs.

[0110] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0111] Based on the same inventive concept, the embodiment of the present application also provides a battery charging device for implementing the battery charging method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more battery charging device embodiments provided below can refer to the limitations of the battery charging method above, and will not be repeated here.

[0127] Among them, the battery management system 101 is the core control unit of the energy storage device, which is responsible for real-time monitoring and management of the operating status of the energy storage battery 103, which may include parameters such as the voltage, current, temperature and health status of the energy storage battery 103. The battery management system 101 collects data such as the voltage, current, temperature and other data of the energy storage battery 103 to evaluate the health status and remaining power of the energy storage battery 103 in real time. When the energy storage battery 103 needs to be charged, the battery management system 101 will control the energy storage inverter 104 to start the corresponding power replenishment process to charge the energy storage battery 103.

[0128] When the energy storage device is connected to the external power grid, the auxiliary power supply 102 will first start and send a wake-up signal to the battery management system 101. The purpose of the wake-up signal is to enable the battery management system 101 to quickly enter the working state after the energy storage is powered on and start monitoring and managing the various operating parameters of the energy storage battery 103.

[0129] The energy storage battery 103 is the main medium for storing electrical energy in the energy storage device. The energy storage battery 103 is usually composed of multiple battery cells, which can be connected in series or in parallel according to specific needs to provide the required voltage and capacity. The main task of the energy storage battery 103 is to store electrical energy generated by the external power grid or renewable energy, and release the electrical energy when needed to meet electricity demand or support the stable operation of the power grid.

[0130] The energy storage converter 104 is the core device for power conversion, responsible for converting the AC power from the external power grid into DC power that the energy storage battery 103 can accept, and adjusting the charging voltage and current according to the instructions of the battery management system 101 to achieve the best charging effect. At the same time, the energy storage converter 104 also has a bidirectional power conversion capability. When the battery is discharged, it can convert the DC power in the energy storage battery 103 into AC power and feed it back to the external power grid to support the load regulation of the external power grid or provide backup power.

[0131] In the above embodiment, after receiving the wake-up signal, if it is determined that the current working mode of the energy storage device is the transport mode, the access signal of the energy storage device is detected; when it is determined that the access signal is an AC signal, the energy storage inverter is controlled to charge the energy storage battery to a preset state of charge; compared with the method of replenishing the energy storage battery by an additional power replenishment device in the traditional technology, the embodiment of the present application integrates the energy storage battery and the energy storage inverter, so there is no need to set up additional power replenishment equipment, which effectively reduces the cost of replenishment. In addition, the integrated energy storage battery and energy storage inverter can reduce the connection complexity and configuration requirements between devices, which reduces the cost of connection between devices and reduces the time and labor cost of installation and maintenance. Finally, by charging according to the working mode and access signal after receiving the wake-up signal, the energy storage device can optimize the charging operation and reduce the cost. This strategy not only improves the efficiency of charging, but also effectively reduces unnecessary power consumption and power costs.
