Embodiment 1

Figure 1 is a flow chart of a charging control method provided in Embodiment 1 of the present application. This embodiment can be applied to the situation of controlling battery charging. The method can be executed by a charging control device, and the device can be implemented by software and/or hardware. , and configured in the charging control device.

Refer to the charging control method shown in Figure 1, which is applied to the client and includes the following steps.

S110. Determine the current discharge amount of the battery at the current moment, and determine whether the charging start conditions are met based on the current moment and/or the current discharge amount.

The current discharge amount may be the total discharge amount of the battery at the current moment, which is used to determine whether the charging start conditions are met. The battery is equipped with a sensor, which obtains the current discharge amount of the battery in real time. The charging starting condition may be a starting condition for determining whether the battery needs to be charged.

For example, the charging start condition may be the length of time since the last charging ended, that is, regular charging according to the length of time. For example, determining whether the charging start condition is met based on the current time may be based on the time difference between the current time and the end of the last charging to determine whether the charging start condition is met. For example, the charging start condition may also be the amount of discharge from the end of the last charge, that is, charging according to the amount of discharge. For example, based on the difference between the current discharge amount at the current moment and the discharge amount at the end of the last charge, it is determined whether the charging start condition is met. The charging start condition may include at least one of the current moment and the current discharge amount. For example, the charging start condition may be that any one of the current moment and the current discharge amount satisfies the condition, then it is determined that the charging start condition is met.

S120. If the charging start conditions are met, the battery is controlled to be charged according to the preset constant current, and the accumulated charging time is recorded.

If it is satisfied, the charging start conditions are met. After the charging start conditions are met, the battery is charged according to the preset constant current, and timing is started through the sensor to record the cumulative charging time. The preset constant current is a preset small current with constant magnitude, which is used to control the magnitude of the current for charging the battery. For example, the preset constant current can be any value in the range of 0-2A (ampere, the international unit of current).

There is no limit on the charging voltage of the battery, as long as the minimum charging voltage is 0.2V higher than the battery voltage, and the maximum charging voltage is lower than the maximum tolerable voltage of the battery or the environment in which the battery is located, ensuring that the battery is always in a charging state and does not exceed the tolerable range of the battery. . For example, when charging the battery in the vehicle, the maximum charging voltage is lower than 16V, ensuring that the battery is always in a charged state and does not exceed the tolerable range of the vehicle's low-voltage power grid. Other charging methods are prohibited during battery charging. For example, when charging the battery in the vehicle, power generation control strategy modes, such as brake recovery and temperature adjustment, are prohibited.

The main reason for the aging and loss of activity of the battery may be that the positive and negative electrodes of the battery are converted into sulfuric acid. lead. Lead sulfate is an insulator. Because the internal resistance of the battery is very large at this time, charging with conventional constant voltage will cause charging difficulties. Charging with constant current can convert part of the lead sulfate into active substances, reduce the internal resistance of the positive and negative electrodes, repair the battery to a certain extent, and extend the service life of the battery.

S130. If the cumulative charging time reaches the first charging time, determine whether the current power of the battery reaches the preset power threshold.

The first charging duration may be a time length condition used to trigger the determination of the current power of the battery. For example, the first charging time may be 4 hours. If the accumulated charging time reaches the first charging time, it is determined whether the current power of the battery reaches the preset power threshold. When the battery is not discharging, the net charging time of the battery can be determined. Because in practice, during the charging process of the battery, the battery may be discharged at the same time. For example, the battery of a vehicle may provide power to the vehicle during the charging process, so the first charging time may be greater than or equal to the net charging time. For example, the first charging duration can be determined based on experiments and experience, which is not limited in this application.

The preset power threshold may be a preset power threshold used to determine whether charging is completed. For example, the preset power threshold may be 98% of the battery power. During the charging process of the battery, there will be other power recovery. For example, the braking recovery of the vehicle can be equivalent to charging the battery in the vehicle. Therefore, the preset power threshold is smaller than the battery power, which avoids overcharging of the battery and helps to extend the life of the battery.

S140. If the current power of the battery reaches the preset power threshold, stop charging the battery.

If so, that is, the current power of the battery is equal to the preset power threshold. If the current power of the battery reaches the preset power threshold, charging of the battery will be stopped to avoid overcharging, damaging the battery and reducing battery life.

If not, that is, the current power of the battery is less than the preset power threshold, continue charging the battery until the current power of the battery is equal to the preset power threshold.

The technical solution of this embodiment determines the current discharge amount of the battery at the current moment, and determines whether the charging start conditions are met based on the current moment and/or the current discharge amount. Determine whether the charging start conditions are met based on the current moment and/or current discharge amount, and judge from the two dimensions of time and power to avoid judging by a single condition, which may cause the battery to be damaged due to low battery power. If the charging start conditions are met, the control will charge the battery according to the preset constant current and record the cumulative charging time. Charging the battery with a constant current can repair the battery to a certain extent, delay the aging of the battery, and extend the life of the battery. If the cumulative charging time reaches the first charging time, it is determined whether the current power of the battery reaches the preset power threshold; if the current power of the battery reaches the preset power threshold, charging of the battery is stopped. By judging from the two dimensions of time and power, we can stop charging the battery in time to prevent overcharging and damage to the battery and extend the life of the battery. Therefore through this The technical solution applied for solves the problem that controlling charging voltage based on temperature cannot delay the aging of the battery and improve the life of the battery. It achieves the effect of delaying the aging of the battery and increasing the life of the battery.

Embodiment 2

Figure 2 is a flow chart of a charging control method provided in Embodiment 2 of the present application. The technical solution of this embodiment is explained on the basis of the above technical solution.

Determining whether the charging start condition is met based on the current time and/or the current discharge amount, including: determining whether the time start condition in the charging start condition is met based on the current time; and/or determining whether the charging start condition is met based on the current discharge amount. The discharge amount starting conditions are used to illustrate the charging starting conditions.

Referring to a charging control method shown in Figure 2, it includes the following steps.

S210. Determine the current discharge amount of the battery at the current moment.

S220: Determine whether the time start condition among the charging start conditions is met based on the current time; and/or determine whether the discharge amount start condition among the charging start conditions is met based on the current discharge amount.

The time start condition may be a basis for determining whether the charging start condition is met based on time. For example, the time difference between the current time and the last charging completion time can be determined based on the current time, and whether the time start condition is met can be determined based on the time difference.

The discharge amount starting condition may be a basis for determining whether the charging starting condition is met based on the discharge amount. For example, the difference between the current discharge amount and the last charging completion time can be determined based on the current discharge amount, and it can be determined based on the discharge amount difference whether the discharge amount starting condition is met.

The charge start condition may include at least one of a time start condition and a discharge amount start condition. For example, the time start condition and the discharge amount start condition can be determined in real time at the same time. If any one of the charging start conditions is met, it is determined that the charging start condition is met.

In an optional embodiment, determining whether the time start condition in the charging start condition is met based on the current time includes: obtaining the last charging completion time; determining the charging interval based on the last charging completion time and the current time; and determining the charging interval based on the charging interval. , determine whether the time start condition is met.

The battery's sensor records the moments when the battery changes state in real time and stores them. For example, when the battery completes charging, the time of completion of charging is recorded and stored. When the battery is being charged, the charging interval between the current time and the time when the last charge was completed is calculated. For example, the charging interval is the difference between the current time and the last charging completion time.

The charging interval is compared with a preset charging interval threshold. If the charging interval is greater than or equal to the preset charging interval threshold, it is determined that the time start condition is met. Otherwise, that is, the charging interval is less than the preset charging interval threshold, it is determined that the time start condition is not met. For example, the preset charging interval threshold may be 2880 hours. The preset charging interval threshold can be determined based on experiments or experience. This application No restrictions.

By obtaining the last charging completion time, the charging interval is determined based on the last charging completion time and the current time; based on the charging interval, it is determined whether the time start condition is met. The battery can be charged regularly according to the time interval to maintain the power in the battery. Avoid power loss and reduce battery loss.

In an optional embodiment, determining whether the discharge amount start condition in the charging start condition is met based on the current discharge amount includes: obtaining the historical total discharge amount of the battery at the time when the last charge was completed; The total discharge amount of the battery is used to determine the total discharge amount difference; based on the total discharge amount difference, it is determined whether the discharge amount starting conditions are met.

The historical total discharge amount can be the total discharge amount corresponding to the moment when the battery completed the latest charge, and is used to determine whether the discharge amount starting conditions are met. For example, the battery's sensor obtains the discharge amount of the battery in real time. When the battery completes a charge, the total discharge amount at the completion time is recorded as the historical total discharge amount. The battery sensor obtains the total discharge amount of the battery at the current moment in real time, and calculates the difference between the total discharge amount of the battery at the current moment and the historical total discharge amount. For example, the total discharge amount difference is the difference between the total discharge amount of the battery at the current moment and the historical total discharge amount.

The total discharge amount difference is compared with a preset total discharge amount difference threshold. If the total discharge amount difference is greater than or equal to the preset total discharge amount difference threshold, it is determined that the discharge amount starting condition is met. Otherwise, that is, the total discharge amount difference is less than the preset total discharge amount difference threshold, it is determined that the discharge amount starting condition is not met. For example, the preset total discharge capacity difference threshold may be 10 times the nominal capacity of the battery. The preset total discharge amount difference threshold can be determined based on experiments or experience, and is not limited in this application.

By obtaining the historical total discharge amount of the battery at the time when the last charge was completed; determining the difference in total discharge amount based on the historical total discharge amount and the total discharge amount of the battery at the current moment; determining whether the discharge amount is satisfied based on the difference in total discharge amount According to the starting conditions, the battery can be charged in time according to the difference in total discharge amount. Charging can maintain the activity of the battery, increase the life of the battery, and maintain the power in the battery, avoid power loss, and reduce the loss of the battery.

S230. If the charging start conditions are met, the battery is controlled to be charged according to the preset constant current, and the accumulated charging time is recorded.

S240. If the cumulative charging time reaches the first charging time, determine whether the current power of the battery reaches the preset power threshold.

S250. If the current power of the battery reaches the preset power threshold, stop charging the battery.

The technical solution of this embodiment refines the charging start by determining whether the time start condition among the charging start conditions is met based on the current moment; and/or determining whether the discharge amount start condition among the charging start conditions is met based on the current discharge amount. Judgment of conditions, refine the charging start conditions into time start bar According to the start-up conditions of components and discharge amount, the charging start-up conditions are judged from the two dimensions of time and discharge amount, and the battery is charged in time to avoid battery aging, extend the life of the battery, and avoid battery power loss.

Embodiment 3

Figure 3 is a flow chart of a charging control method provided in Embodiment 3 of the present application. The technical solution of this embodiment is explained on the basis of the above technical solution.

If the cumulative charging time reaches the first charging time, then determining whether the current power of the battery reaches the preset power threshold may include: if the cumulative charging time reaches the first charging time, then determining whether the cumulative charging time reaches the second charging time; wherein, The second charging time is longer than the first charging time; if the cumulative charging time does not reach the second charging time, it is determined whether the current power of the battery reaches the preset power threshold to illustrate the judgment process before stopping charging the battery.

After stopping charging the battery, it may also include: updating the historical total discharge amount according to the total discharge amount of the battery at the current moment to update the historical total discharge amount.

Referring to a charging control method shown in Figure 3, it includes the following steps.

S310. Determine the current discharge amount of the battery at the current moment, and determine whether the charging start conditions are met based on the current moment and/or the current discharge amount.

S330. If the accumulated charging time reaches the first charging time, determine whether the accumulated charging time reaches the second charging time, where the second charging time is longer than the first charging time.

The second charging time can be used to determine whether the charging time is too long. The second charging time is longer than the first charging time. For example, the second charging time may be 48 hours. If the cumulative charging time is longer than the second charging time, it can be determined that the charging time is too long, which may easily cause damage to the battery. Therefore, when the charging time reaches the second charging time, corresponding measures can be taken to speed up the charging process, reduce the damage to the battery, and extend the battery life.

In an optional embodiment, if the cumulative charging time reaches the second charging time, the vehicle start-stop function of the vehicle where the battery is located is prohibited, and it is determined whether the current power of the battery reaches the preset power threshold.

The vehicle start-stop function is the starting and stopping function of the vehicle. The moment the vehicle starts and stops, it will cause a large loss of power. If the accumulated charging time reaches the second charging time, that is, if the accumulated charging time is greater than the second charging time, the vehicle start-stop function is disabled at this time to speed up the charging process. After disabling the vehicle start-stop function of the vehicle where the battery is located, it is determined in real time whether the current power of the battery reaches the preset power threshold. After reaching the preset power threshold, that is, greater than the preset power threshold, the disabled vehicle can be unlocked. Vehicle start and stop function.

By disabling the vehicle start-stop function of the vehicle where the battery is located if the cumulative charging time reaches the second charging time, and determining whether the current power of the battery reaches the preset power threshold, the vehicle can be disabled in time after the cumulative charging time reaches the second charging time. The start-stop function reduces the loss of power, accelerates the charging process, and by judging whether the current battery power reaches the preset power threshold, promptly lifts the prohibition of the vehicle start-stop function, making it easier for users to use the vehicle and improving the user experience.

S340. If the cumulative charging time does not reach the second charging time, determine whether the current power of the battery reaches the preset power threshold.

If not, that is, the cumulative charging time is less than or equal to the second charging time. At this time, the charging time is within the conventional charging time range. It is determined in real time whether the current power of the battery reaches the preset power threshold, and charging of the battery is stopped in a timely manner.

S350. If the current power of the battery reaches the preset power threshold, stop charging the battery.

S360. Update the historical total discharge amount according to the total discharge amount of the battery at the current moment.

The battery sensor obtains the total discharge amount of the battery when charging of the battery is stopped. As the latest historical total discharge amount, the historical total discharge amount before this charge is updated to provide an updated historical total discharge amount for the next charge to ensure follow-up. The correctness of the judgment of discharge amount starting conditions.

The technical solution of this embodiment is to determine whether the accumulated charging time reaches the second charging time if the accumulated charging time reaches the first charging time; wherein the second charging time is greater than the first charging time; the second charging time is performed on the charging time. judgment. If not, determine whether the current power of the battery reaches the preset power threshold. If not, determine whether the current power of the battery reaches the preset power threshold, continue to judge whether the charging is completed, and stop charging the battery in time to avoid battery failure. Overcharging will damage the battery. By updating the historical total discharge amount based on the total discharge amount of the battery at the current moment, the updated historical total discharge amount is provided for the next charge, ensuring the accuracy of subsequent judgments on the discharge amount starting conditions.
