Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first" and "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Fig. 1 is a flowchart of a charging control method according to an embodiment of the present disclosure, where the present embodiment is applicable to a situation of controlling charging of a storage battery, and the method may be executed by a charging control device, and the charging control device may be implemented by software and/or hardware and is specifically configured in the charging control device.
The charging control method shown in fig. 1 is applied to a client, and specifically includes the following steps:
and S110, determining the current discharge amount of the storage battery at the current moment, and determining whether the charging starting condition is met according to the current moment and/or the current discharge amount.
The current discharge capacity can be the total discharge capacity of the storage battery at the current moment and is used for judging whether the charging starting condition is met. The storage battery is provided with a sensor which acquires the current discharge amount of the storage battery in real time. The charge start condition may be a start condition that determines whether or not charging is required.
For example, the charge start condition may be a time period from the end of the last charge, that is, a periodic charge according to the time period. Specifically, whether the charging start condition is satisfied is determined according to the current time, which may be determining whether the charging start condition is satisfied according to a time difference between the current time and the last time when charging is completed. For example, the charge start condition may also be a discharge amount from the end of the last charge, that is, charged by the discharge amount. Specifically, whether the charge starting condition is met is determined according to the difference value between the current discharge amount at the current moment and the discharge amount at the last charge end. The charge start condition may include at least one of a current time and a current discharge amount. For example, the charge start condition may be that any one of the current time and the current discharge amount satisfies the condition, and it is determined that the charge start condition is satisfied.
And S120, if so, controlling to charge the storage battery according to the preset constant current, and recording the accumulated charging time.
If the charging start condition is met, the charging start condition is also met. And after the charging starting condition is met, charging the storage battery according to the preset constant current, starting timing through the sensor, and accumulating the charging time. The preset constant current is a preset small current with constant magnitude and is used for controlling the magnitude of the current for charging the storage battery. For example, the preset constant current may be any value of 0 to 2A (amperes, international unit of current).
It should be noted that the charging voltage of the storage battery is not limited, and only the lowest charging voltage is higher than the voltage of the storage battery by 0.2V, and the highest charging voltage is lower than the maximum tolerable voltage of the storage battery or the environment where the storage battery is located, so as to ensure that the storage battery is always in a charging state and does not exceed the tolerable range of the storage battery. For example, when charging a battery in a vehicle, the maximum charging voltage is below 16V, ensuring that the battery is always in a charged state and does not exceed the vehicle low voltage grid sustainable range. Other charging modes are disabled during battery charging. Illustratively, the power generation control strategy modes, such as brake recovery and temperature regulation, are disabled when charging the battery in the vehicle.
The aging and loss of activity of the battery may be mainly due to the conversion of both the positive and negative electrodes of the battery into lead sulfate. Lead sulfate is an insulator, and since the internal resistance of the secondary battery is large at this time, charging using a conventional constant voltage causes charging difficulty. The constant current charging can convert part of lead sulfate into active substances, reduce the internal resistance of the anode and the cathode, realize the repair of the battery to a certain degree and prolong the service life of the battery.
And S130, if the accumulated charging time reaches the first charging time, judging whether the current electric quantity of the storage battery reaches a preset electric quantity threshold value.
The first charging duration may be a time length condition for triggering determination of the current electric quantity of the storage battery. For example, the first charging period may be 4 hours. Specifically, if the accumulated charging duration reaches the first charging duration, whether the current electric quantity of the storage battery reaches a preset electric quantity threshold is judged. In the case of a non-discharged battery, the net charge time of the battery may be determined. The first charging period may be greater than or equal to the net charging period, since in practice the battery may be discharged during charging of the battery at the same time, for example the battery of a vehicle may supply power to the vehicle during charging. Specifically, the method comprises the following steps. The first charging period may be determined experimentally and empirically, and the application is not specifically made to this end.
The preset electric quantity threshold may be a preset electric quantity threshold for determining whether charging is completed. For example, the preset charge threshold may be 98% of the battery charge. During the charging of the battery, there may be other electrical energy recovery, for example, the braking recovery of the vehicle, which may be equivalent to charging the battery in the vehicle. Therefore, the preset electric quantity threshold value is smaller than the electric quantity of the storage battery, the storage battery is prevented from being overcharged, and the service life of the storage battery is prolonged.
And S140, if so, stopping charging the storage battery.
If yes, the current electric quantity of the storage battery is equal to the preset electric quantity threshold value. If so, the storage battery is stopped being charged, thereby avoiding overcharging, damaging the storage battery and reducing the service life of the storage battery.
If not, that is, the current electric quantity of the storage battery is smaller than the preset electric quantity threshold, the storage battery continues to be charged until the current electric quantity of the storage battery is equal to the preset electric quantity threshold.
According to the technical scheme of the embodiment, whether the charging starting condition is met or not is determined by determining the current discharge amount of the storage battery at the current moment and according to the current moment and/or the current discharge amount. Whether the charging starting condition is met or not is judged according to the current moment and/or the current discharging amount, judgment is carried out from two dimensions of time and electric quantity, and the condition that the judgment is carried out through a single condition to cause that the electric quantity of the storage battery is too low to damage the storage battery is avoided. And if so, controlling to charge the storage battery according to the preset constant current, and recording the accumulated charging time. The storage battery is charged by constant current, so that the storage battery can be repaired to a certain extent, the aging of the storage battery can be delayed, and the service life of the storage battery is prolonged. If the accumulated charging time reaches the first charging time, judging whether the current electric quantity of the storage battery reaches a preset electric quantity threshold value; if yes, the charging of the storage battery is stopped. Through judging from two dimensions of time and electric quantity, in time stop to battery charging, prevent overcharge, damage the battery, further improve the life-span of battery. Therefore, by means of the technical scheme, the problems that the aging of the storage battery cannot be delayed and the service life of the storage battery cannot be prolonged by controlling the charging voltage according to the temperature are solved, and the effects of delaying the aging of the storage battery and prolonging the service life of the storage battery are achieved.
Example two
Fig. 2 is a flowchart of a flowchart method of a charging control method provided in the second embodiment of the present application, and the technical solution of the present embodiment is further refined on the basis of the above technical solution.
Further, the "determination of whether the charge starting condition is satisfied according to the current time and/or the current discharge amount" is refined as follows: determining whether a time starting condition in the charging starting conditions is met or not according to the current moment; and/or determining whether a discharge amount starting condition' in the charge starting condition is satisfied according to the current discharge amount to refine the charge starting condition.
Referring to fig. 2, a charging control method includes:
and S210, determining the current discharge amount of the storage battery at the current moment.
S220, determining whether a time starting condition in the charging starting conditions is met or not according to the current moment; and/or determining whether the discharge amount starting condition in the charge starting condition is met according to the current discharge amount.
The time starting condition may be a judgment basis for determining whether the charge starting condition is satisfied according to time. Specifically, a time difference from the last charging completion time may be determined according to the current time, and whether the time start condition is satisfied may be determined according to the time difference.
The discharge amount starting condition may be a judgment criterion for determining whether the charge starting condition is satisfied according to the discharge amount. Specifically, a difference value between the current discharge amount and the discharge amount at the last charging completion time can be determined according to the current discharge amount, and whether the discharge amount starting condition is met or not can be judged according to the discharge amount difference value.
The charge start condition may include at least one of a time start condition and a discharge amount start condition. For example, the time starting condition and the discharge amount starting condition may be determined in real time, and if any one of the charge starting conditions is satisfied, it is determined that the charge starting condition is satisfied.
In an alternative embodiment, determining whether a time starting condition among the charge starting conditions is satisfied according to the current time includes: acquiring the last charging completion moment; determining a charging interval according to the last charging completion time and the current time; and determining whether a time starting condition is met or not according to the charging interval.
And the sensor of the storage battery records the time of the change of different states of the storage battery in real time and stores the time. For example, when the storage battery finishes charging, the charging completion time is recorded and stored. When the storage battery is charged, the charging interval between the current time and the last charging completion time is calculated. Specifically, the charging interval is a difference obtained by subtracting the last charging completion time from the current time.
And comparing the charging interval with a preset charging interval threshold, and if the charging interval is greater than or equal to the preset charging interval threshold, determining that a time starting condition is met. Otherwise, that is, the charging interval is smaller than the preset charging interval threshold, it is determined that the time starting condition is not satisfied. For example, the preset charging interval threshold may be 2880 hours. The preset charging interval threshold may be determined experimentally or empirically, and is not specifically limited in this application.
Obtaining the last charging completion time; determining a charging interval according to the last charging completion time and the current time; according to the charging interval, whether the time starting condition is met or not is determined, the storage battery can be charged regularly according to the time interval, the electric quantity in the storage battery is maintained, the electric quantity loss is avoided, and the loss of the storage battery is reduced.
In an alternative embodiment, determining whether the discharge amount starting condition among the charge starting conditions is satisfied according to the current discharge amount includes: acquiring the historical total discharge capacity of the storage battery at the last charging completion moment; determining a total discharge capacity difference value according to the historical total discharge capacity and the total discharge capacity of the storage battery at the current moment; and determining whether the discharge capacity starting condition is met or not according to the total discharge capacity difference value.
The historical total discharge capacity can be the corresponding total discharge capacity at the moment when the storage battery finishes the latest charging, and is used for judging whether the discharge capacity starting condition is met. Specifically, a sensor of the storage battery acquires the discharge capacity of the storage battery in real time, and after the storage battery is charged once, the total discharge capacity at the completion moment is recorded as the historical total discharge capacity. And a sensor of the storage battery acquires the total discharge capacity of the storage battery at the current moment in real time, and calculates the difference between the total discharge capacity of the storage battery at the current moment and the historical total discharge capacity. Specifically, the total discharge amount difference is a difference obtained by subtracting the historical total discharge amount from the total discharge amount of the storage battery at the current moment.
And comparing the total discharge difference with a preset total discharge difference threshold, and if the total discharge difference is greater than or equal to the preset total discharge difference threshold, determining that the discharge starting condition is met. Otherwise, if the total discharge capacity difference is smaller than the preset total discharge capacity difference threshold, the discharge capacity starting condition is determined not to be met. For example, the preset total discharge amount difference threshold may be 10 times the nominal capacity of the battery. The preset total discharge amount difference threshold may be determined according to experiments or experience, and this is not specifically limited in this application.
Obtaining the historical total discharge capacity of the storage battery at the last charging completion moment; determining a total discharge capacity difference value according to the historical total discharge capacity and the total discharge capacity of the storage battery at the current moment; whether the discharge capacity starting condition is met or not is determined according to the total discharge capacity difference value, the storage battery can be charged in time according to the total discharge capacity difference value, the activity of the storage battery is maintained through charging, the service life of the storage battery is prolonged, the electric quantity in the storage battery is maintained, the electric quantity loss is avoided, and the loss of the storage battery is reduced.
And S230, if so, controlling to charge the storage battery according to the preset constant current, and recording the accumulated charging time.
S240, if the accumulated charging time reaches the first charging time, whether the current electric quantity of the storage battery reaches a preset electric quantity threshold value is judged.
And S250, if so, stopping charging the storage battery.
According to the technical scheme of the embodiment, whether the time starting condition in the charging starting condition is met or not is determined according to the current moment; and/or determining whether a discharging amount starting condition in the charging starting condition is met or not according to the current discharging amount, refining the judgment of the charging starting condition, refining the charging starting condition into a time starting condition and a discharging amount starting bar, judging the charging starting condition from two dimensions of time and discharging amount, charging the storage battery in time, avoiding the aging of the storage battery, prolonging the service life of the storage battery, and avoiding the loss of the electric quantity of the storage battery.
