Referring to fig. 2, the method for remotely boosting the voltage and checking the capacity of the storage battery comprises the following steps:
s201: determining a centralized controller corresponding to a storage battery needing to be subjected to capacity checking according to a capacity checking request, and generating a capacity checking control instruction pointing to the storage battery, wherein the capacity checking request is sent by a management terminal.
The storage battery comprises a plurality of single batteries, the charging ends of the single batteries are connected to the output end of the switching power supply through a lead or a connecting bar, the power supply ends of the single batteries are connected to a direct current load through the DC/DC boosting module, and the single batteries are mutually connected in series and jointly used as a standby power supply of the switching power supply. One DC/DC boost module may boost a battery cell corresponding to one battery cell, and may boost a plurality of battery cells corresponding to a plurality of battery cells (for example, a plurality of battery cells are divided into one group, and one DC/DC boost module corresponds to one group of battery cells).
Further, the DC/DC boost module is connected with the single-cell nuclear capacitor control device, the DC/DC boost module is controlled by the single-cell output voltage controlled by the single-cell nuclear capacitor control device, the single-cell nuclear capacitor control device is connected with the centralized controller through an RS485 connection wire, the centralized controller is communicated with the remote boost nuclear capacitor device of the storage battery through a remote transmission network, and after receiving an instruction issued by the remote boost nuclear capacitor device of the storage battery, the centralized controller issues the instruction to the single-cell corresponding nuclear capacitor control device according to the storage battery ID attached by the instruction.

The storage battery remote voltage boosting and capacity checking device can be integrated on a management platform such as a server and a cloud server.
For example, when the storage battery needs to be controlled to perform boosting and capacity checking, a capacity checking request is sent to the storage battery remote boosting and capacity checking device through the management terminal, and after receiving the capacity checking request, the storage battery remote boosting and capacity checking device determines the centralized controller corresponding to the storage battery needing to perform capacity checking according to the capacity checking request, and generates a capacity checking control instruction pointing to the centralized controller and the corresponding storage battery.
Optionally, when the management terminal is used to send out the core capacity request, the storage battery needing the boost core capacity is determined, and the core capacity request is generated according to the determined storage battery and sent to the storage battery remote boost core capacity device. For example, the storage battery may be selected by inputting a storage battery ID, a storage battery selection list, or the like, a capacity check request directed to the storage battery may be generated based on the selected storage battery ID, and the capacity check request may be transmitted to the storage battery remote voltage-boosting capacity check device.

The segmentation strategy can be to sequentially control one or more battery monomers to perform capacity checking according to a preset time interval until the capacity checking of all the battery monomers is completed. After the segmentation strategy is determined, the device ID determined according to the core-capacity sequence of the battery cell is sent to the core-capacity control device connected to the battery cell based on the communication address of the battery cell.

Specifically, after the operation state information of each battery cell is determined, the operation state information is compared with a preset nuclear capacity requirement to judge whether each battery cell meets the nuclear capacity requirement, and the battery cell which does not meet the nuclear capacity requirement is determined as an abnormal cell.
For example, the discharge amount of the battery cell is determined according to the operation state information, and is compared with the rated capacity of the battery cell or the preset discharge amount in the corresponding discharge time period, so as to determine whether the actual capacity of the battery cell meets the requirement, and if the discharge amount is lower than the rated capacity or the preset discharge amount, the battery cell is considered as an abnormal cell.

The device ID or the corresponding relationship between the installation location and the battery cell may be recorded in a form, a linked list, a pointer, or the like, which is not limited in this embodiment.
For example, when a battery cell is determined to be an abnormal cell because the discharge amount is less than the rated capacity by more than a preset threshold, the device ID of the battery cell is determined, and abnormal warning information indicating that the device ID and the discharge amount do not meet the requirements is generated. Or when the battery cell is determined to be an abnormal cell because the battery temperature exceeds the temperature threshold value in the discharging process, determining the equipment ID of the battery cell and generating abnormal alarm information pointing to the equipment ID and the working temperature which do not meet the requirement.

Specifically, the method comprises the following steps: storing the operation parameter information of the single battery to a historical parameter data table; and determining the change trend information of the battery monomer according to the historical parameter data table.
For example, after receiving the operation parameter information of the battery cell, the storage location of the historical operation parameter of the battery cell in the historical parameter data table is determined according to the device ID of the battery cell, and the received operation parameter information is stored as the newly added historical operation parameter in the corresponding storage location of the historical parameter data table.

After the parameter change trend is determined, the slope corresponding to the parameter change trend is determined, the slope is compared with a preset slope threshold, when the slope exceeds the preset slope threshold, the parameter corresponding to the battery monomer is considered to be abnormal, abnormal change information can be generated, and the abnormal change information is sent to the management terminal.
