[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In order to solve the problem in the related art that if an error is detected during the power-on process, the power-on process will be stopped, which greatly affects the power-on efficiency when power-on is needed to deal with emergencies in an emergency, the embodiment of the present invention provides a power-on method, device, electronic device and storage medium for an energy storage integrated cabinet. In response to a power-on instruction, a first self-check process is performed on multiple indicators of the energy storage integrated cabinet to obtain a first check result, and an operation mode is determined based on the first check result. When the operation mode is a maintenance mode, the self-check threshold of the target indicator is adjusted to the target self-check threshold, and then a second self-check process is performed based on the target self-check threshold to obtain a second check result. The operation mode is determined based on the second check result. When the operation mode is a hardware self-check mode, it is determined whether to power on the energy storage integrated cabinet based on the self-check result of the hardware self-check mode. In this method, the power-on process is promoted without affecting safety by adding a maintenance mode, thereby improving the power-on efficiency.

[0028] To facilitate understanding of this embodiment, a power-on method for an energy storage integrated cabinet disclosed in an embodiment of the present invention is first introduced in detail.

[0029] Example 1

[0030] The embodiment of the present invention provides a method for powering on an energy storage integrated cabinet. Figure 1 The following is a flow chart of a method for powering on an energy storage integrated cabinet provided by an embodiment of the present invention. Figure 1 As shown, the power-on method of the energy storage integrated cabinet may include the following steps:

[0031] Step S101, in response to a power-on instruction, a first self-check process is performed on a plurality of indicators of the energy storage integrated cabinet to obtain a first check result.

[0032] The first self-check process may include a self-check process executed by a battery management system and a self-check process executed by an energy storage converter.

[0033] Among them, the indicators of self-test run by the battery management system may include single cell information, total battery voltage information, current signal information, temperature information, relay adhesion information, insulation information, etc., and the indicators of self-test run by the energy storage inverter may include short circuit information, overvoltage information, overfrequency information, insulation information and hardware adhesion information.

[0034] The first inspection result represents the fault conditions of the respective multiple indicators. If a preset self-checking threshold is met, it is determined that there is no fault, and if the self-checking threshold is not met, it is determined that there is a fault.

[0035] Furthermore, before performing a first self-check process on multiple indicators of the energy storage integrated cabinet to obtain a first inspection result, the method may also include: judging the communication status, if a communication failure occurs, stopping power supply, if there is no communication failure, performing a first self-check process on multiple indicators of the energy storage integrated cabinet to obtain a first inspection result.

[0036] Among them, the battery management system and energy storage inverter have corresponding display screens. If a communication failure occurs, a prompt will be given through the display screen.

[0037] Step S102: determining the operation mode based on the first inspection result.

[0038] The operation mode may include a maintenance mode, a hardware self-check mode, and a troubleshooting mode.

[0039] Among them, the maintenance mode is a mode that can only be entered when a target indicator fails. It is used to relax the self-check threshold of the target indicator without affecting safety, so as not to affect the power-on process when power-on is urgently needed, thereby improving the power-on efficiency.

[0040] Among them, the hardware self-test mode is a mode that can be entered when the corresponding self-tests of the battery management system and the energy storage converter are passed, and is used to perform hardware self-test.

[0041] Among them, the pending troubleshooting mode is a mode that can be entered under the premise that a fault indicator appears and the fault indicator does not meet the requirements for entering the maintenance mode, and is used to prompt the staff to inspect the components corresponding to the indicator.

[0042] Step S103: If the operation mode is the maintenance mode, the self-check threshold of the target indicator is adjusted to the target self-check threshold.

[0043] The range of the self-test threshold is smaller than the range of the target self-test threshold. By relaxing the range of the self-test threshold, power-on is not affected when power-on is urgently needed, thereby improving power-on efficiency.

[0044] Step S104: performing a second self-check process based on the target self-check threshold to obtain a second check result.

[0045] Among them, the second self-check processing is aimed at the self-check of the battery management system operation, which is used to perform a secondary self-check on the target indicator. When the target indicator meets the target self-check threshold, the power-on process continues to improve the power-on efficiency.

[0046] Step S105, determining the operation mode based on the second inspection result.

[0047] Wherein, when the second inspection result is that the target indicator meets the target self-check threshold, the operation mode is determined to be the hardware self-check mode.

[0048] Step S106: If the operation mode is the hardware self-test mode, determine whether to power on the energy storage integrated cabinet based on the self-test result of the hardware self-test mode.

[0049] Among them, the battery management system and the energy storage converter correspond to different hardware self-test modes respectively. The battery management system includes self-test corresponding to the circuit breaker status and self-test of the pre-charge condition, and the energy storage converter at least includes self-test corresponding to the circuit breaker status and self-test of the pre-charge condition.

[0050] The power-on method of the energy storage integrated cabinet provided in the embodiment of the present invention can perform a first self-check process on multiple indicators of the energy storage integrated cabinet in response to a power-on instruction to obtain a first check result, determine the operation mode based on the first check result, and when the operation mode is the maintenance mode, adjust the self-check threshold of the target indicator to the target self-check threshold, and then perform a second self-check process based on the target self-check threshold to obtain a second check result, determine the operation mode based on the second check result, and when the operation mode is the hardware self-check mode, determine whether to power on the energy storage integrated cabinet based on the self-check result of the hardware self-check mode. In this method, the power-on process is promoted without affecting safety by adding a maintenance mode, thereby improving the power-on efficiency.

[0051] Example 2

[0052] The embodiment of the present invention also provides another method for powering on an integrated energy storage cabinet; this method is implemented on the basis of the method in the above embodiment.

[0053] Figure 2 A flowchart of another method for powering on an energy storage integrated cabinet provided in an embodiment of the present invention, such as Figure 2 As shown, the power-on method of the energy storage integrated cabinet may include the following steps:

[0054] Step S201, in response to a power-on instruction, a first self-check process is performed on a plurality of indicators of the energy storage integrated cabinet to obtain a first check result.

[0055] Specifically, a first self-inspection process is performed on multiple indicators of the energy storage integrated cabinet to obtain a first inspection result, including: based on a plurality of pre-set first self-inspection thresholds, a plurality of first indicators of the energy storage integrated cabinet are respectively self-inspected to obtain a first sub-inspection result; the first self-inspection process is executed by a battery management system; based on a plurality of pre-set second self-inspection thresholds, a plurality of second indicators of the energy storage integrated cabinet are respectively self-inspected to obtain a second sub-inspection result; the second self-inspection process is executed by an energy storage inverter; and the first inspection result is determined based on the first sub-inspection result and the second sub-inspection result.

[0056] Among them, the first indicator may include single cell information, total battery voltage information, current signal information, temperature information, relay adhesion information, insulation information, etc., and the second indicator may include short circuit information, overvoltage information, overfrequency information, insulation information and hardware adhesion information.

[0057] Each of the above information has a corresponding self-check threshold, and whether a fault occurs is determined by comparing it with the self-check threshold, thereby determining the first inspection result.

[0058] Specifically, Table 1 is a comparison table of indicators and self-test thresholds under normal charging and discharging conditions:

[0059] Table 1:

[0060]

[0061] Step S202: determining the operation mode based on the first inspection result.

[0062] Specifically, when the second sub-inspection result indicates that multiple second indicators all meet the corresponding second self-inspection threshold: if the first sub-inspection result indicates that the target indicator does not meet the corresponding first self-inspection threshold, and the indicators other than the target indicator among the multiple first indicators all meet the corresponding first self-inspection threshold, then the operation mode is determined to be the maintenance mode; if the first sub-inspection result indicates that there are indicators other than the target indicator among the multiple first indicators that do not meet the corresponding first self-inspection threshold, then the operation mode is determined to be the troubleshooting mode.

[0063] When the second sub-inspection result indicates that there is an indicator among the plurality of second indicators that does not meet the corresponding second self-inspection threshold value: determining the operation mode to be checked mode.

[0064] Step S203: If the operation mode is the maintenance mode, the self-check threshold of the target indicator is adjusted to the target self-check threshold.

[0065] Among them, when it is determined that the target indicator has a fault, the battery management system will feedback to the EMS whether to execute the maintenance mode. If feedback to execute the maintenance mode is received within the preset waiting time, the maintenance mode will be executed, otherwise it will enter the troubleshooting mode.

[0066] The preset waiting time may be 30 minutes.

[0067] Among them, the target indicators may include: single cell voltage, cluster total voltage, pack total voltage, temperature, temperature difference, pressure difference and state of charge; the specific fault causes may be single cell voltage too low, cluster total voltage too low, pack total voltage too low, temperature too low, temperature difference too large, pressure difference too large and state of charge too low.

[0068] Specifically, Figure 3 A comparison diagram of maintenance mode processing measures provided by an embodiment of the present invention, such as Figure 3 As shown in the figure, the abnormal conditions of the target indicators in the maintenance mode, condition thresholds (target self-test thresholds), trigger time, recovery time, charge and discharge modes, processing measures, alarm level reporting, and manual processing measures are described in detail.

[0069] Step S204: compare the target indicators that do not meet the first self-check threshold with the corresponding target self-check threshold to obtain a second check result.

[0070] Step S205: If the second inspection result indicates that there is a target indicator that does not meet the target self-inspection threshold, the operation mode is a waiting-for-inspection mode.

[0071] Step S206: If the second inspection result indicates that the target indicators all meet the target self-check threshold, the operation mode is the hardware self-check mode.

[0072] The hardware self-test mode includes: a first hardware self-test mode run by the battery management system and a second hardware self-test mode run by the energy storage converter; the self-test result includes: a first self-test result corresponding to the first hardware self-test mode and a second self-test result corresponding to the second hardware self-test mode;

[0073] Step S207: If the operation mode is the hardware self-test mode, determine whether to power on the energy storage integrated cabinet based on the self-test result of the hardware self-test mode.

[0074] Specifically, the self-test result is determined as follows: self-test the state of the circuit breaker corresponding to the battery management system to determine whether the circuit breaker is closed; if the circuit breaker is closed, close the main negative relay and the pre-charge relay; after closing the main negative relay and the pre-charge relay, if a preset percentage of pre-charge is reached within a preset time, disconnect the pre-charge relay and close the total positive relay to determine that the first self-test result is passed; perform a self-test of the second hardware self-test mode on the energy storage inverter to obtain a second self-test result; wherein the self-test of the second hardware self-test mode includes at least a self-test of the state of the circuit breaker corresponding to the energy storage inverter and a self-test of the pre-charge; the second self-test result includes a passed self-test and a failed self-test.

[0075] Among them, the preset time can be 3 seconds, the preset percentage can be 90%, and the pre-charging resistor burning out, the pre-charging resistor being too large, the load short circuit, the high-voltage component short circuit, etc. may all cause the pre-charging to fail to meet the preset percentage.

[0076] Among them, the circuit breaker will open and close during self-inspection, and the circuit breaker will send the current working status to the battery management system. This action is considered to be feedback from the circuit breaker, so it can be determined whether the circuit breaker is closed. Otherwise, it is considered that the circuit breaker has no feedback and a fault has occurred.

[0077] If both the first self-test result and the second self-test result are through, the energy storage integrated cabinet is powered on; otherwise, the operation mode is switched to the to-be-checked mode.

[0078] For ease of understanding, Figure 4 A schematic diagram of a power-on strategy for an energy storage integrated cabinet provided in an embodiment of the present invention, such as Figure 4 As shown, after receiving the power-on command, the communication status can be judged first. When there is no fault in the communication status, the self-test of the battery management system and the self-test of the energy storage converter can be performed at the same time. Each self-test has a corresponding self-test indicator. When there is no fault in each indicator, or when only the target indicator has a fault but there is no fault after passing the maintenance mode, it can be considered that the self-test has passed, and the hardware self-test mode is entered. After the self-test result of the hardware self-test mode indicates that there is no fault, the self-test is completed, the high voltage is powered on, and the EMS instruction is waited.

[0079] It should be noted that the maintenance mode is only performed once for each self-test.

[0080] It should be noted that after the hardware self-test mode corresponding to the battery management system ends, it is necessary to exit the insulation test; after receiving the power-on command, it is also necessary to make a communication judgment on the EMS. If a communication failure occurs, the corresponding display screen of the EMS will also display it.

[0081] The power-on method for the energy storage integrated cabinet provided in the embodiment of the present invention can be performed by the battery management system and the energy storage converter to run self-tests in parallel, which saves the time for self-tests, and the power-on is performed after both have passed the self-tests, which improves the power-on safety, and when the battery management system runs the self-test, if the target indicator does not meet the first self-test threshold, the self-test threshold of the target indicator is amplified within a safe range, so as to realize power-on in the scenario where power-on is urgently needed, thereby improving the power-on efficiency.
