and S100, determining the battery life of each battery replacement.
As described above, most of the replaced batteries of the electric vehicle are only difficult to meet the use requirements of the electric vehicle, most of the replaced batteries still have a certain electric energy storage function, even a part of the replaced batteries can still be used as power batteries of the electric vehicle after professional capacity expansion processing, and accordingly, the replaced batteries other than the two cases completely lose the function of storing electric energy, are difficult to continue to use, and can only be discarded.
According to the basic principle of the energy storage battery, the energy storage battery has a definite service life correspondingly, and the service life of the energy storage battery is correspondingly shortened along with the weakening of the performance of the battery.
Optionally, in the process of determining the battery life of each battery replacement cell, first, target parameters of each battery replacement cell are respectively obtained, specifically, the target parameters described in this embodiment include at least one of a charging frequency, a battery internal resistance, and a cell voltage of the battery replacement cell, and certainly, other parameters capable of representing the performance and the operating state of the battery replacement cell may also be included, which are not listed here one by one, and on the premise that the scope of the core idea of the present invention is not exceeded, the present invention also belongs to the scope protected by the present invention. In practical applications, the electronic device executing the processing method provided by the embodiment of the invention may establish a communication connection with the battery replacement unit through the CAN bus, and obtain the target parameter by accessing the battery management unit of the battery replacement unit.
After the target parameters are obtained, the battery life of the battery replacement battery can be calculated according to the obtained target parameters. Taking the internal resistance of the battery as an example as a target parameter, after the internal resistance of the battery replacement is obtained, the internal resistance is compared with the rated internal resistance of the battery replacement when the battery is delivered from a factory, so that the SOH value of the battery replacement is estimated according to the change ratio of the internal resistance of the battery, and the service life of the battery replacement is further obtained. For the calculation of the battery life based on other target parameters, the calculation can be implemented based on the prior art, and will not be described herein.
And S110, respectively determining the battery type of each battery to be replaced according to the service life of the battery.
The embodiment of the invention realizes the division of the battery types mainly based on the relation between the battery life of the battery replacement battery and the preset life threshold, and can roughly divide the battery replacement battery into three types based on the difference of the battery life:
one of the two types of batteries is a type of battery that can be used by a vehicle, and as can be seen from the foregoing, after capacity expansion processing is performed on a part of the battery replacement batteries, the power supply requirement of the electric vehicle can still be met.
And the second type of battery can be used for energy storage, if the battery is difficult to meet the power supply requirement of the electric automobile even after capacity expansion treatment, but has a certain electric energy storage function and still has further utilization value, the battery can be applied to an energy storage power station, and the battery is determined as the second type of battery in the embodiment of the invention.
And the third is three types of batteries which cannot be used continuously and need to be discarded, and the batteries can only be disassembled.
Optionally, based on the classification principle, a flowchart of the method for classifying battery replacement batteries according to the embodiment of the present invention can be seen in fig. 4, specifically,
and S200, taking each battery to be replaced as a battery to be classified.
Optionally, in practical application, a set of all battery swapping batteries may be used as a battery swapping battery set, in the process of determining the battery type, each battery swapping battery in the battery swapping battery set is used as a battery to be classified, the battery life of the battery to be classified is compared with a corresponding life threshold, the type of the battery to be classified is determined according to the comparison result, all the battery swapping batteries in the battery swapping battery set are traversed, and thus the process of determining the types of all the battery swapping batteries is completed.
It is conceivable that the number of the battery replacement batteries in the battery replacement total set may be reasonably selected according to the data processing capability of the electronic device, and the number of the battery replacement batteries is not limited in the present invention.
S210, judging whether the battery life of the battery to be classified is larger than a first life threshold value, if so, executing S220, and if not, executing S230.
Specifically, a first life threshold is preset, and the first life threshold is determined according to the performance requirement of the electric vehicle on the energy storage battery, and may be a minimum life value of the energy storage battery when the energy storage battery is used as a power battery of the electric vehicle.
It is conceivable that performance requirements of different vehicles for the power battery are different, and therefore, when the method is applied to a specific project, the value of the first life threshold value should be determined in combination with the requirements of the specific vehicle, and if the battery replacement batteries of the same specification are applied to different types of vehicles, different first life threshold values should be set for different types of vehicles, so as to accurately determine whether the battery replacement batteries can be applied to the vehicles.
And S220, determining the battery to be classified as a class of battery.
In combination with the above, in the case that the battery life of the battery to be classified is greater than the first life threshold, the battery to be classified may be determined as a class of battery.
And S230, judging whether the battery life of the battery to be classified is less than or equal to the first life threshold and greater than the second life threshold, if so, executing S240, and if not, executing S250.
And if the battery life of the battery to be classified is not greater than, namely less than or equal to the first life threshold, further judging whether the battery life of the battery to be classified is greater than a second life threshold.
In this embodiment, the second life threshold is set based on the performance requirement of the energy storage power station for the energy storage battery, and it can be understood that the energy storage battery applied to the energy storage power station has a charging and discharging function, and meanwhile, there is a requirement for the minimum capacity of the energy storage battery for the purpose of stability of operation of the energy storage power station and convenience of energy storage management. It is conceivable that the aforementioned first lifetime threshold value is larger than the second lifetime threshold value in this step.
And S240, determining that the battery to be classified is a second-class battery.
And if the battery life of the battery to be classified is less than or equal to the first life threshold and greater than the second life threshold, determining the type of the battery to be classified as a second type of battery, and in practical application, the battery to be classified can be used as an energy storage battery in an energy storage power station.
And S250, determining the batteries to be classified into three types of batteries.
And if the battery life of the battery to be classified is less than or equal to the second life threshold, determining that the type of the battery to be classified is three types of batteries and discarding the batteries.
And S120, respectively processing the corresponding battery replacement batteries according to a preset processing method corresponding to the battery types to which the battery replacement batteries belong.
According to the battery replacement processing method provided by the embodiment of the invention, the corresponding preset processing methods are respectively provided for each type of battery, and the processing methods of different types of battery replacement are different, so that the differentiation and targeted processing of the battery replacement can be realized, and further the full utilization and proper processing of different types of battery replacement can be realized.
When the method is specifically executed, each battery replacement battery is respectively used as a target battery replacement battery, then a target preset processing method corresponding to the battery type of the target battery replacement battery is determined according to the preset corresponding relation between the battery type and the preset processing method, and the corresponding target battery replacement battery is processed according to the target preset processing method.
In practical applications, it is conceivable that each of the battery replacement batteries is simultaneously used as a target battery replacement battery, and then each of the target battery replacement batteries is processed simultaneously, or that some of all the battery replacement batteries are used as target battery replacement batteries one by one, and then the target battery replacement batteries with relatively small total number are processed. The specific choice should be determined mainly by combining the computing capability of the electronic device and the requirement for processing efficiency, which is not limited in the present invention.
Optionally, if the target battery replacement battery is a type of battery, the preset centralized charging station is controlled to expand the capacity of the target battery replacement battery, and the charging process is performed after the capacity expansion. The energy storage capacity of the target battery replacement battery after capacity expansion can be repaired to a certain degree, and the battery replacement battery can be continuously used for the electric automobile after being fully charged. In practical application, the fully charged batteries can be transported to a power exchanging station for use by the power exchanging station.
Optionally, if the target battery replacement battery is a three-class battery and cannot be used continuously, the battery disassembling system is controlled to disassemble the target battery replacement battery.
Optionally, if the target battery replacement battery is a secondary battery, the target battery replacement battery is used in the energy storage power station, and stores electric energy with other energy storage batteries in the energy storage power station or supplements electric energy to the alternating current power grid, so as to play a role of an electric energy buffer battery. The specific processing procedure of such a battery will be described in the following with specific flow charts, and will not be detailed here.
In summary, in the battery replacement processing method provided in the embodiment of the present invention, after the battery life of each battery replacement is determined, the battery replacement is classified according to the battery life, the battery replacement is divided into different types, meanwhile, corresponding preprocessing methods are set for different battery types, and after the battery type to which any battery replacement belongs is determined, the battery replacement is processed according to the preprocessing method corresponding to the battery type to which the battery replacement belongs, so that differentiated processing on the battery replacement in different states can be achieved, the battery replacement can be fully utilized and properly processed, and further, the actual application requirements are met.
The following describes the process of replacing batteries of type two. Based on the foregoing, the battery replacement processing method provided in the embodiment of the present invention applies the two types of batteries to the energy storage power station, and in practical applications, the energy storage power supply of the energy storage power station is mostly provided with a new energy power supply, such as at least one of a wind power generation system and a photovoltaic power generation system, in addition to the ac power grid, and by cooperation between the energy storage battery, the new energy power supply and the ac power grid, the purposes of peak clipping and valley filling and full utilization of new energy electric energy are achieved.
On the basis of fig. 5, fig. 5 is a flowchart of another battery replacement processing method according to an embodiment of the present invention, and on the basis of the embodiment shown in fig. 3, the flowchart specifically shows a processing flow for the two types of batteries, specifically,
s300, judging whether the current time belongs to the power consumption valley time period, if so, executing S310, and if not, executing S320.
When the second type battery is processed, the electricity utilization time interval to which the current time belongs is firstly judged, if the current time belongs to the electricity utilization valley time interval, S310 is executed, and conversely, if the current time belongs to the electricity utilization peak time interval, S320 is executed.
It is conceivable that the division of the power consumption valley period and the power consumption peak period is different due to different load characteristics of a specific power supply area and a power supply area, and in practical application, the division may be determined by combining practical situations. Moreover, for any natural day, 24 hours of the day are divided into a power consumption valley period and a power consumption peak period, and only these two time intervals exist, so that, in this step, if the current time does not belong to the power consumption valley period, it naturally belongs to the power consumption peak period.
And S310, controlling the energy storage power supply to charge the target battery replacement battery.
In the time of power consumption, the load of the power supply network is light, the electricity price is low, and the energy storage power supply can be controlled to charge the target battery replacement battery, so that the electric energy is stored at low cost. It is to be understood that the energy storage power source for charging the target battery replacement may be at least one of an ac power grid and a new energy power source.
And S320, determining the power generation capacity of the new energy power supply.
Through the judgment of the steps, if the current time belongs to the electricity peak time period, the target battery replacement battery needs to be controlled to discharge to the alternating current power grid so as to supplement the power supply capacity of the alternating current power grid.
In the case where the energy storage power source includes a new energy power source, it is first necessary to determine the power generation capacity of the new energy power source. It should be noted that, in most cases, the power generation capacity of the new energy power source may be represented by power generation power, where a higher power generation power represents a stronger power generation capacity, and correspondingly, the capacity threshold mentioned in the following description is represented by a power threshold. Of course, the output voltage of the new energy power supply can be selected to represent the power generation capacity, and in practical application, any parameter capable of measuring the operation state of the new energy power supply is optional, and the parameter also belongs to the protection scope of the invention on the premise of not exceeding the core idea scope of the invention.
S330, judging whether the power generation capacity of the new energy is smaller than a preset capacity threshold value, if so, executing S340, and if not, executing S350.
If the power generation capacity of the new energy power supply is smaller than the preset capacity threshold, it indicates that the output electric energy of the new energy power supply is deficient, and the energy storage power station should be used for supplementing the electric energy of the power grid to meet the power consumption requirement of the load, so that S340 needs to be executed, and conversely, if the power generation capacity of the new energy power supply is larger than or equal to the preset capacity threshold, it is considered that the output electric energy of the new energy power supply is sufficient, and S350 is executed.
And S340, controlling the target battery replacement battery to discharge to the alternating current power grid.
Under the condition that the power generation capacity of the new energy power supply is insufficient, the target battery replacement battery is controlled to discharge to the alternating current power grid, and the load power is supplemented, so that the load power consumption requirement is met.
And S350, controlling the new energy power supply to charge the target battery replacement battery and output power to the alternating current power grid.
Under the condition that the power generation capacity of the new energy power supply is sufficient, the new energy power supply is controlled to simultaneously output electric energy to the target battery replacement battery and the alternating current power grid, so that the electric energy output by the new energy power supply is fully utilized as far as possible.
As can be seen from the above execution procedure, in the valley period, regardless of the power generation capability of the new energy power supply, the target secondary battery needs to be charged to store electric energy at the lowest possible cost. And in the electricity utilization time interval, the electricity generation capacity of the new energy power supply needs to be processed differently.
It should be noted that, the target battery replacement described in any of the above embodiments may specifically be at least one battery replacement, and the specific number of the target battery replacement may be determined by combining the processing capability of the system.
In summary, the battery replacement processing method provided by the invention can not only perform differentiation processing on the battery replacement, but also realize full utilization and proper processing on the battery replacement, and can achieve the purposes of peak clipping and valley filling and full utilization of new energy electric energy.
