[0002] Currently, with the continuous growth of the country's economic strength, people's daily lives are becoming more and more convenient. Many people will choose to buy batteries prepared for energy storage power sources when they don't want to charge. This consumption trend has led to people's increasing requirements for energy storage batteries.

[0003] In existing technologies, all the batteries in the user's electric terminal are often used as the demand basis. The energy storage power supply then stores the batteries according to the generated demand basis. However, this method generates a large number of unstable batteries in the demand basis, resulting in low efficiency of the energy storage power supply and increasing the time it takes for the energy storage power supply to complete the battery storage. Especially when there are a large number of electric terminals, the energy storage power supply has a limited speed, which may prolong the waiting time of the user due to the inability to complete the battery storage in time.

[0004] There is currently no effective solution to the problem of low battery energy storage efficiency in related technologies.

[0046] To address the aforementioned issues, this embodiment provides a battery management method for an energy storage system. Figure 1 This is a flowchart of a battery management method for an energy storage system according to an embodiment of the present invention, the process including the following steps:

[0047] Step S202: Based on the demand data collection instruction transmitted from the energy storage demand side, parse the demand data string in the demand data collection instruction;

[0048] Step S204: Find at least two sub-demand bases for target electricity from the demand base package information corresponding to the demand base string, wherein the demand base package information corresponding to the demand base string includes multiple sub-demand bases for different electricity levels.

[0049] Step S206: Merge the sub-demand bases with the same battery discharge voltage among the sub-demand bases of the at least two target energy quantities into a target demand base, and generate a battery energy storage command based on the target demand base.

[0050] The above steps address the issue of low battery energy storage efficiency in related technologies. Furthermore, by generating battery energy storage commands based on merged target demand, the energy storage efficiency based on demand is improved.

[0051] Optionally, in an exemplary embodiment, merging the sub-demand bases with the same battery discharge voltage among the at least two target power sub-demand bases into a target demand base includes: determining the battery discharge voltage of each sub-demand base among the at least two target power sub-demand bases; collecting the first target power sub-demand base and the second target power sub-demand base with the same battery discharge voltage; and merging the first target power sub-demand base and the second target power sub-demand base into the target demand base.

[0052] Optionally, in an exemplary embodiment, after merging the sub-demand bases with the same battery discharge voltage into a single target demand base, the method further includes: determining the modified energy amount of the target demand base transmitted by the energy storage demand terminal according to the demand base modification instruction transmitted by the energy storage demand terminal; and modifying the energy storage energy amount according to the modified energy amount when the difference between the energy storage energy amount of the target demand base and the modified energy amount is greater than a first threshold, thereby obtaining the modified target energy storage energy amount of the target demand base.

[0053] In one embodiment, the modified power can be set to not exceed the energy storage power based on the target demand. In this case, the first threshold can be determined between 0 and the energy storage power.

[0054] Optionally, in an exemplary embodiment, after merging the sub-demand bases of target capacity with the same battery discharge voltage into a target demand base, and generating a battery energy storage instruction based on the target demand base, the method further includes: determining the discharge efficiency corresponding to the energy storage capacity of the target demand base; and transmitting a first prompt message to the energy storage demand end when it is determined that the energy storage capacity of the target demand base is greater than the maximum usage corresponding to the discharge efficiency, wherein the first prompt message is used to prompt the energy storage demand end to modify the discharge efficiency corresponding to the energy storage capacity of the target demand base.

In this way, the target power demand threshold can effectively adapt to the complex and variable operation of the battery, preventing battery failure while improving battery performance under various operating conditions and effectively enhancing the user experience.

[0059] It should be noted that by combining the sub-demands based on the above-mentioned demand determined by the reservation time and the energy storage priority, energy storage batteries can be stored according to the customer's reservation time, thus improving the customer experience.

[0060] In one embodiment, the energy storage priority based on the target demand can be adjusted according to the energy storage capacity based on the target demand, thereby increasing the energy storage priority based on the target demand with a larger energy storage capacity.

[0061] Optionally, in an exemplary embodiment, in the process of merging the sub-demand criteria for target quantities with the same battery discharge voltage into a target demand criterion, the method further includes: merging the resistance quantities corresponding to the same battery discharge voltage in the sub-demand criteria for target quantities with the same battery discharge voltage, and determining the merging result as the target resistance quantity in the target demand criterion; and merging the inductance quantities corresponding to the same battery discharge voltage in the sub-demand criteria for target quantities with the same battery discharge voltage, and determining the merging result as the target inductance quantity in the target demand criterion.

[0062] In one embodiment, the resistance quantity in the target requirement basis can also be reset according to the target inductance quantity in the target requirement basis.

[0063] Through the above embodiments, it is possible to improve the efficiency of battery energy storage while ensuring that the target demand is based on the corresponding battery discharge voltage.

[0064] Optionally, in an exemplary embodiment, the method further includes: when it is determined that the battery discharge voltage of the sub-demand basis of the target power in the demand basis package information corresponding to the demand basis string is different, generating a battery energy storage sub-instruction for each sub-demand basis of the target power with different battery discharge voltages.

[0065] Optionally, in an exemplary embodiment, the method further includes: setting an independent sales code for each sub-demand basis within the demand basis package information to realize independent and combined sales of the sub-demand basis; and, in the case of combined sales of the sub-demand basis, setting a combined discount for the combined sales of the sub-demand basis to increase the sales volume of the sub-demand basis.

[0066] Optionally, in an exemplary embodiment, the method further includes: collecting the historical energy storage duration of the battery, predicting the battery completion time based on the historical energy storage duration, and displaying the battery energy storage completion time to the energy storage demand side when it is determined that the battery completion time is less than a fourth threshold, thereby improving the customer experience. The fourth threshold is set based on the historical energy storage duration and does not exceed the historical energy storage duration.
