EXAMPLE III
Fig. 4 is a flowchart of a method for maintaining an energy storage power supply according to a third embodiment of the present invention, where a relationship between this embodiment and the above embodiments is to control charging and discharging of the energy storage power supply based on the battery state information to refine maintenance of the energy storage power supply, and optionally, the battery state information includes a number of battery cycles; based on this, as shown in fig. 4, the energy storage power maintenance method includes:
and S310, acquiring the battery state information.

And S331, determining whether the range is larger than a first threshold value.
If yes, go to step S240, otherwise, go to step S210.
And S341, controlling the single battery corresponding to the highest single battery voltage to discharge for a preset time and executing the step of calculating the range of the voltages of the plurality of single batteries again until the range is smaller than the first threshold value.
And S322, determining whether the battery cycle number reaches a preset number.
The battery cycle times refer to the battery charging and discharging times, when the battery charging and discharging times of the energy storage power supply are too many, attenuation may exist, the actual capacity of the energy storage power supply is determined when the preset times are reached, the actual capacity of the energy storage power supply is periodically checked, and the potential safety hazard caused by too much attenuation of the energy storage power supply is prevented. The predetermined number of times may be set according to the user's requirement, and may be, for example, 80 times, 90 times, 100 times, 105 times, etc.
If so, go to step S332, otherwise go to step S322.
S332, determining the actual capacity of the energy storage power supply, determining whether the energy storage power supply needs to be replaced or not based on the actual capacity and the initial rated capacity, and sending a replacement instruction when the energy storage power supply needs to be replaced.
The lithium battery is used in most of the existing energy storage power supplies, and the attenuation of the battery can be caused due to the characteristics of the lithium battery along with the increase of the number of use cycles, so that the service life and the safety are influenced. The initial rated capacity refers to a capacity value calibrated when the energy storage power supply leaves a factory, and with the increase of the use times, the actual capacity of the energy storage power supply changes and may not be consistent with the initial rated capacity. When the difference between the actual capacity of the energy storage power supply and the initial rated capacity is too large, it indicates that the energy storage power supply may be damaged and cannot be used continuously, and the user safety may be affected by the continuous use. The replacement instruction can be sent to a maintenance person, the replacement instruction is an instruction for instructing the maintenance person to replace a product, and at the moment, the maintenance person can mark that the energy storage power supply can not be lent any more and needs to be scrapped and replaced.
Therefore, after the cycle number of the battery reaches the preset number, the actual capacity of the energy storage power supply is determined, whether the energy storage power supply needs to be replaced is determined based on the actual capacity and the initial rated capacity, and a replacement instruction is sent when the energy storage power supply needs to be replaced, so that the energy storage power supply which cannot be continuously used can be replaced in time, and the safety of a user is prevented from being affected.

The determining the actual capacity of the energy storage power source comprises:
and controlling the energy storage power supply to be fully charged until S0C is 100%.
And controlling the energy storage power supply to discharge until the SOC is 0%.
And determining the full discharge capacity value of the energy storage power supply from 100% of S0C to 0% of SOC as the actual dischargeable capacity.
And controlling the energy storage power supply to be fully charged until S0C is 100%.
And determining the full charge capacity value of the energy storage power supply from 0% of S0C to 100% of SOC as the actual chargeable capacity.
The SOC is short for state-of-charge, refers to the charging state of the automobile battery, is also called residual capacity, and represents the capacity of the battery for continuous operation. The following is a specific explanation of SOC: SOC is generally the ratio of charge capacity to rated capacity, expressed as a percentage. One battery generally has a rated capacity, and when the battery is charged for a certain time under a certain multiplying power, you can obtain the charging capacity, and the ratio of the charging capacity to the rated capacity is the SOC. The value range is 0 to 1, the SOC is 0% and represents that the battery is completely discharged, and the SOC is 100% and represents that the battery is completely charged. Therefore, the actual dischargeable capacity can be determined by discharging the energy storage power source from 100% at S0C to the full discharge capacity with 0% at SOC, and the actual chargeable capacity can be determined by charging the energy storage power source from 0% at S0C to the full charge capacity with 100% at SOC.
In an alternative embodiment of the present invention, the determining whether the energy storage power source needs to be replaced based on the actual capacity and the initial rated capacity includes:
it is determined whether the ratio of the actual capacity to the initial rated capacity is less than a second threshold.
And if so, determining that the energy storage power supply needs to be replaced.
And if not, determining that the energy storage power supply does not need to be replaced.
Wherein, with the increase of the use times, the actual capacity of the energy storage power supply changes and may not be consistent with the initial rated capacity. When the difference between the actual capacity of the energy storage power supply and the initial rated capacity is too large, it is indicated that the energy storage power supply may be damaged and cannot be used continuously, and the safety of a user may be affected by the continuous use. The second threshold value is a ratio of actual capacity to initial rated capacity when the energy storage power supply can not be used any more, when the ratio of the actual capacity to the initial rated capacity is smaller than the second threshold value, it is indicated that the energy storage power supply can not be lent any more and needs to be scrapped and replaced, it is determined that the energy storage power supply needs to be replaced, and when the ratio of the actual capacity to the initial rated capacity is not smaller than the second threshold value, it is indicated that the energy storage power supply can be used any more. In a specific embodiment, the second threshold may be 70% -90%, in particular 75%, 77%, 80%, 82%, 85% etc.
In an optional embodiment of the present invention, after determining that the energy storage power supply does not need to be replaced, the method further includes:
and writing the actual capacity into the energy storage power supply through the communication module and taking the actual capacity as a calibrated capacity value of the energy storage power supply.
The communication module can communicate with the energy storage power supply through the UART, at the moment, the actual capacity is written into the energy storage power supply product through UART communication to finish the calibration of the energy storage power supply, and the calculation precision of the SOC of the energy storage power supply product can be corrected by writing the actual capacity into the energy storage power supply through the communication module and taking the actual capacity as the calibrated capacity value of the energy storage power supply.
