Wherein, the charge-discharge current information of the prior art is fixed, as shown in Table 1,

TABLE 1

The following will describe the technical scheme of the present disclosure in detail:

fig. 1 shows a flowchart of a charge-discharge current information adjustment method 100 according to an embodiment of the present disclosure. The method 100 may include:

step 110, determining the current theoretical capacity attenuation of the battery according to the current running information of the vehicle;

the current travel information may be a current total travel distance of the vehicle, a current total use duration, and the like.

According to the historical running information and capacity attenuation obtained through statistics of big data, an expected capacity attenuation function can be obtained, then the current running information is substituted into the capacity attenuation function, and the current theoretical capacity attenuation of the battery can be calculated, wherein the current theoretical capacity attenuation is also the capacity attenuation expected by a vehicle manufacturer under the current running information.

Step 120, determining the current actual capacity decay of the battery according to the current battery information of the battery;

current battery information includes, but is not limited to, current maximum capacity, cut-off voltage, etc. actual test results.

Step 130, dynamically adjusting charge-discharge current information according to the current theoretical capacity fade and the current actual capacity fade, wherein the charge-discharge current information includes: the charge-discharge current and/or the charge-discharge current multiplying power.

The current theoretical capacity attenuation and the current actual capacity attenuation respectively represent the battery capacity attenuation expected by the manufacturer and the current actual capacity attenuation of the vehicle, and the current actual capacity attenuation is closely related to the charging and discharging habits of users, so that according to the current theoretical capacity attenuation and the current actual capacity attenuation, the charging and discharging current information is adjusted, the adjusted charging and discharging current information is not fixed and unchanged but can be adaptively changed along with the charging and discharging habits of the users, and the charging and discharging current information is changed based on the current theoretical capacity attenuation, so that under the same charging and discharging habits, the charging and discharging current information which can be used by the users is changed along with the theoretical capacity attenuation expected by the manufacturer, the battery attenuation of the users gradually tends to the capacity attenuation expected by the manufacturer, and therefore, the current actual capacity attenuation of different users is more close to the current theoretical capacity attenuation expected by the manufacturer through the scheme of the disclosure, and the battery attenuation perception of different users tends to be consistent for the vehicles with the same type of batteries, so that the satisfaction degree of the users is improved.

Of course, the dynamic adjustment of the charge-discharge current information is not a real-time adjustment but is performed according to a longer period, such as performing the adjustment of the present disclosure once a half year/year, so as to avoid the adverse effect on the battery caused by too frequent adjustment.

In some embodiments, said dynamically adjusting charge-discharge current information based on said current theoretical capacity fade and said current actual capacity fade comprises:

and dynamically adjusting charge-discharge current information according to the current battery attenuation difference value, wherein when the current theoretical capacity attenuation is larger than the current actual capacity attenuation, the larger the current battery attenuation difference value is, the larger the adjusted charge-discharge current information is, and when the current theoretical capacity attenuation is smaller than the current actual capacity attenuation, the larger the current battery attenuation difference value is, and the smaller the adjusted charge-discharge current information is.

Comparing the current theoretical capacity attenuation with the current actual capacity attenuation to calculate a current battery attenuation difference value, if the current theoretical capacity attenuation and the current actual capacity attenuation are respectively Z0 and Zactual capacity attenuation, the current battery attenuation difference value is | (Zactual-Z0) |/Z0 or || (Zactual-Z0) |, then the charge-discharge current information is dynamically adjusted according to the current battery attenuation difference value, specifically, because the battery is more quickly attenuated after long-term use of large charge-discharge current information, the current theoretical capacity attenuation is greater than the current actual capacity attenuation, the current battery attenuation difference value is greater, which indicates that a user belongs to a conservative user, and the current theoretical capacity attenuation is far greater than the current actual capacity attenuation after long-term use of small current multiplying power or slow charge/slow discharge, therefore, the charge-discharge current information needs to be adjusted to be larger, so that the current multiplying power or current used by the user can be properly increased, namely, the current multiplying power or current used by the user becomes larger, and likewise, when the current theoretical capacity fade is smaller than the current actual capacity fade, the larger the current battery fade difference value is, the more the user belongs to the aggressive user, the long-term use of the large current multiplying power or the large current fast charge/fast discharge and the violent driving are indicated, so that the current theoretical capacity fade is far smaller than the current actual capacity fade, the charge-discharge current information needs to be adjusted to be smaller, so that the current multiplying power or current used by the user can be properly reduced, namely, the current multiplying power or current used by the user becomes smaller, therefore, the capacity attenuation of the batteries of different vehicles tends to be more equal to the theoretical capacity attenuation expected by manufacturers, and the attenuation perception of the batteries by different users tends to be equal, so that the user satisfaction degree is improved.

In some embodiments, the dynamically adjusting charge-discharge current information according to the present battery attenuation difference includes:

the preset corresponding relation can be expressed by a table or a discrete function curve, and if the accuracy requirement is not high, a continuous coefficient adjustment function can be fitted according to the existing battery attenuation difference in the corresponding relation and the corresponding adjustment coefficient, wherein the coefficient adjustment function takes the battery attenuation difference value ((actual-Z0)/Z0) as an input and takes the adjustment coefficient a of the charge and discharge current information as a function of an output value, as shown in fig. 2A.

After the corresponding relation between the battery attenuation difference of the charge and discharge current information and the adjustment coefficient is obtained, the adjustment coefficient of the charge and discharge current information can be obtained according to the current battery attenuation difference value and the corresponding relation, and then multiplication operation is carried out on the charge and discharge current information pre-stored in the vehicle and the adjustment coefficient of the charge and discharge current information, so that the adjusted charge and discharge current information can be accurately obtained.

Of course, if the adjustment coefficient corresponding to the current battery attenuation difference value cannot be found from the corresponding relation, interpolation operation can be performed on two battery attenuation difference values most adjacent to the current battery attenuation difference value in the corresponding relation and the adjustment coefficients corresponding to the two most adjacent battery attenuation difference values, so as to obtain the adjustment coefficient corresponding to the current battery attenuation difference value. Specifically, the adjusted charge-discharge current information may be as shown in table 2:

TABLE 2

Wherein a (i, j) (representing adjustment coefficients of a, B, C, etc., i, j representing the number of rows and columns in table 2) =w ((actual-Z0)/Z0) in table 2, W being a coefficient adjustment function, (actual-Z0)/Z0 being a battery attenuation difference value, and (a 1, a2 … k1, k2 …) in table 2 being charge and discharge current information prestored in the vehicle, that is, fixed values in table 1.

SOC, the state of charge, is a value reflecting the remaining capacity of a battery, and is defined numerically as the ratio of the remaining capacity to the battery capacity, commonly expressed as a percentage. Soc is calculated from the voltage.

And the magnitude of the charge-discharge current is generally expressed by the charge-discharge multiplying power, namely: charge-discharge rate = charge-discharge current/rated capacity; for example: when the battery 20A having a rated capacity of 100Ah is discharged, the discharge rate is 0.2C.

In some embodiments, the correspondence between the battery decay difference and the adjustment coefficient of the charge-discharge current information varies depending on the maximum theoretical allowable charge-discharge current of the battery of the vehicle, and the charge-discharge current safety margin of the battery.

Because the batteries are different, the maximum allowable charge and discharge current of the battery and the charge and discharge current safety boundary of the battery formulated by manufacturers are different, and even if a vehicle with the same type of battery is provided, the normal working temperature of the vehicle may be different, so in order to improve the accuracy of the corresponding relationship between the battery attenuation difference of the charge and discharge current information and the adjustment coefficient, the corresponding relationship between the battery attenuation difference of the charge and discharge current information and the adjustment coefficient may be different according to the maximum allowable charge and discharge current of the battery of the vehicle and the different charge and discharge current safety boundary of the battery.

The safety boundary of the charge and discharge current of the battery is the maximum allowable charge and discharge current of the manufacturer to the user, for example, when the maximum allowable charge and discharge current of the manufacturer is 10A, the maximum allowable charge and discharge current of the manufacturer to the user is usually not 10A, but is slightly lower than 10A, for example, may be 8A, for safety reasons.

Of course, as can be seen from fig. 2A, the correspondence between the battery attenuation difference of the charge-discharge current information and the adjustment coefficient may also be different depending on the temperature.

The following describes the process of adjusting charge-discharge current information in combination with maximum theory allowable charge-discharge current and the charge-discharge current safety margin of the battery:

assuming that the maximum theoretical allowable charge-discharge current is 12A and the maximum allowable charge-discharge current indicated by the charge-discharge current safety boundary of the battery is 10A, and assuming that the theoretical capacity fade Z0 of the battery given by the manufacturer after 3 years of use is 10% and the current actual capacity fade is 5%, the current theoretical capacity fade is smaller than the current actual capacity fade, which means that the user is a conservative user, the smaller charge-discharge current/current multiplying power is used for a long time, so that the temperature and the charge-discharge current information under the SOC should be properly adjusted, for example, the maximum allowable charge-discharge current is adjusted from 10A to 11A, which is closer to the maximum theoretical allowable charge-discharge current 12A, and the current theoretical capacity fade of the battery given by the manufacturer may become 17%, 18% or even 20% after 3 years of use, which is similar to or the theoretical fade, so that the capacity fade perceived by different users tends to be improved, which is favorable for the manufacturer to the safety maintenance of the vehicle, and the quality of the vehicle, and the safety of the vehicle is beneficial to the user.

In some embodiments, the determining the current actual capacity fade of the battery based on the current battery information of the battery comprises:

The current maximum capacity and the charge/discharge cutoff voltage are related to the actual capacity attenuation of the battery, if the current maximum capacity is larger, the current actual capacity is attenuated, the charge/discharge cutoff voltage is smaller, the maximum chargeable voltage of the battery is smaller, and the capacity attenuation is larger, so that the current actual capacity attenuation can be accurately calculated according to the current maximum capacity and the charge/discharge cutoff voltage of the vehicle.

In some embodiments, the determining the current theoretical capacity fade of the battery according to the current driving information of the vehicle includes:

Because the actual capacity attenuation of the battery is completely different under different running mileage and using time length, the actual capacity attenuation function which takes the running mileage and the using time length as the input and takes the actual capacity attenuation as the output can be obtained through the corresponding actual capacity attenuation under different running mileage and using time length counted by big data, and then the current actual capacity attenuation can be accurately calculated through taking the current total running mileage and the current total using time length of the vehicle as the input of the actual capacity attenuation function.
