As an example, as shown in fig. 2, the battery 100 may include a case 10 and a battery cell 20, and the battery cell 20 is accommodated in the case 10. The case 10 is used to provide an accommodating space for the battery cell 20, and the case 10 may have various structures.

In some alternative embodiments, the status information includes at least one of acceleration information, pressure information.
For example, acceleration information of the battery may be collected using an acceleration sensor. In some examples, the greater the acceleration value of the battery, the more severe the impact the battery may be subjected to.
For another example, a pressure sensor may be used to collect pressure information received by the battery. In some examples, the greater the pressure value experienced by the battery, the more severe the impact the battery may be.
In the embodiment of the application, the acceleration sensor or the pressure sensor can be utilized to timely acquire acceleration information or pressure information, so that the acceleration or the pressure of the battery can be automatically monitored, and the state of the battery can be rapidly detected.
For example, the acceleration sensor or the pressure sensor may be integrated inside the battery, for example, the sensor may be mounted on a case of the battery.
For ease of understanding, the implementation of the steps is illustrated below.
In some alternative embodiments, the status information may include a specific status value of the battery.
As shown in fig. 3, S1 may include S11 and S2 may include S21.
S11, acquiring a state value of the battery.
S21, determining a treatment scheme of the battery according to a comparison result of the state value and the reference threshold value.
In the embodiment of the application, the treatment scheme of the battery can be rapidly determined by comparing the state value of the battery with the reference threshold value.
For example, the state value may include an acceleration value of the battery, and the reference threshold may include a first type of reference threshold corresponding to the acceleration. Alternatively, the state value may comprise a pressure value experienced by the battery and the reference threshold may comprise a second type of reference threshold corresponding to the pressure value experienced.
The magnitude of the reference threshold may be related to the manufacturing process of the battery. For example, in the preparation of a battery, a welding process is required. According to the welding specification, the welding strength of the battery is 135Mpa, and when the force applied to the welding seam is greater than 135Mpa, the welding seam of the battery is broken. For example, in the case where the state value includes a pressure value to which the battery is subjected, in the case where the pressure value to which the battery is subjected is greater than 135MPa, it may be determined that the disposal scheme for the battery is scrapped; in the case where the pressure value to which the battery is subjected is less than or equal to 135MPa, the treatment regimen for the battery may be determined to be maintenance or continued use.
For example, the first type of reference threshold corresponding to the acceleration may be determined through simulation experiments of the collision. For example, the maximum acceleration value which can be born by the battery can be determined in a simulation manner, and the disposal scheme of the battery can be determined to be scrapped under the condition that the acceleration value of the battery is larger than the maximum acceleration value which can be born by the battery; in the case where the acceleration value of the battery is less than or equal to the maximum acceleration value that the battery can withstand, the treatment regimen for the battery may be determined to be maintenance or continued use.
In some alternative embodiments, the reference threshold may include a first reference threshold and a second reference threshold, the first reference threshold being greater than the second reference threshold. As shown in fig. 4, S21 may include S211.
S211, if the state value is greater than a first reference threshold value, determining that the treatment scheme of the battery is scrapped; if the state value is smaller than the second reference threshold value, determining that the treatment scheme of the battery is continuous use; and if the state value is smaller than or equal to the first reference threshold value and larger than or equal to the second reference threshold value, determining that the treatment scheme of the battery is maintenance.
In the embodiment of the application, the state value of the battery is compared with two reference thresholds, so that the condition that the battery is scrapped or is continuously used or maintained can be rapidly determined.
Taking the obtained acceleration value of the battery as an example, the first reference threshold value and the second reference threshold value corresponding to the acceleration can be determined through simulation experiments of collision.
For example, simulation experiments on collisions show that the force applied to the weld bead of the battery reaches the maximum force that the weld bead can withstand at an acceleration of 40g, that is, the maximum acceleration that the battery can withstand is 40g, and 40g can be used as the first reference threshold.
For another example, in the case where the acceleration is less than 20g, as found by simulation experiments of the collision, the battery is not affected by the collision or is not affected by continued use of the battery, and 20g may be used as the second reference threshold.
Under the condition that the acceleration value of the battery is 20 g-40 g, the battery is damaged but not scrapped, so that the battery can be determined to be required to be maintained, and the battery can be used after being maintained.
The above examples regarding the acquisition of the reference threshold value and the size of the reference threshold value are just some examples, and the collision handling method provided by the embodiment of the present application may not be limited thereto.
In some alternative embodiments, as shown in fig. 5, S11 may include S111 and S112, and S21 may include S212.
S111, acquiring a plurality of state values of the battery in a plurality of directions;
s112, determining the maximum state value from a plurality of state values in a plurality of directions.
S212, determining a treatment scheme of the battery according to a comparison result of the maximum state value and the reference threshold value.
In the embodiment of the application, the state values of the battery in multiple directions can be considered, namely the collision condition of the battery in multiple directions can be considered, and the prediction accuracy of the state of the battery can be improved; in addition, comparing the maximum state value to a reference threshold value, the treatment regimen for the battery may be determined more quickly.
In embodiments of the present application, the plurality of directions may include two or more directions.
Taking a battery for a vehicle as an example, as shown in fig. 6, the plurality of directions may include a first direction X, a second direction Y, and a third direction Z. The first direction X may be a forward direction of the vehicle, the third direction Z may be a height direction of the vehicle, and a plane formed by intersecting the second direction Y and the first direction X may be perpendicular to the third direction Z.
In S111, a state value of the battery in the first direction X, a state value of the battery in the second direction Y, and a state value of the battery in the third direction Z may be acquired.
In S212, the maximum state value may be determined from the state value of the battery in the first direction X, the state value of the battery in the second direction Y, and the state value of the battery in the third direction Z.
For example, the reference threshold may include a plurality of reference thresholds, for example, the reference threshold includes a first reference threshold and a second reference threshold, the first reference threshold being greater than the second reference threshold, the first reference threshold and the second reference threshold being determined based on a maximum state value that the battery can withstand in various directions. For example, the maximum value of the maximum state values that the battery can withstand in all directions may be used as the first reference threshold value, and the minimum value of the maximum state values that the battery can withstand in all directions may be used as the second reference threshold value.
Taking the state value including the acceleration value as an example, the maximum acceleration value that can be born by the battery in the first direction X is 40g, the maximum acceleration value that can be born by the battery in the second direction Y is 30g, the maximum acceleration value that can be born by the battery in the third direction Z is 20g, and 40g can be used as a first reference threshold value, and 20g can be used as a second reference threshold value.
In some alternative embodiments, as shown in fig. 7, S11 may include S113 and S114.
S113, acquiring a state value of the battery according to a first period;
and S114, if the state value is greater than the trigger threshold, acquiring the state value of the battery according to a second period, wherein the time length of the first period is greater than the time length of the second period, and the trigger threshold is smaller than the reference threshold.
If the state values of the battery are sampled with a small sampling period during the running of the vehicle, the workload of the processor is excessive, and the performance of the processor is reduced.
In the embodiment of the application, the signal acquisition is performed with a larger sampling period, and the signal acquisition is performed with a smaller sampling period under the condition that the state value is larger than the trigger threshold value, so that the workload of a processor can be reduced, and the accuracy of battery state prediction under the collision condition can be improved.
For example, the trigger threshold may be less than the maximum state value that the battery can withstand in either direction, with the maximum state value that the battery can withstand in different directions. Still taking the state value including the acceleration value as an example, the maximum acceleration value that can be born by the battery in the first direction X is 40g, the maximum acceleration value that can be born by the battery in the second direction Y is 30g, the maximum acceleration value that can be born by the battery in the third direction Z is 20g, and the trigger threshold can be less than 20g. For example, the trigger threshold may be 15g.
For example, the first period and the second period may be determined according to a period of time required for the state value of the battery to increase from the minimum value to the maximum value after the collision occurs. The duration of the first period and the duration of the second period may both be less than the desired duration.
For example, the state value is an acceleration value, and after the collision occurs, the time required for the acceleration value of the battery from 0 to the maximum value is 40ms or more, the time of the first period may be 10ms, and the time of the second period may be 1ms. In S113, acquiring the state value of the battery according to the first period may include: the acceleration value of the battery is acquired every 10 ms. In S114, acquiring the state value of the battery according to the second period may include: the acceleration value of the battery is acquired every 1ms. During the sampling of data according to the first period, the new sample value may overwrite the old sample value.
If the state value of the battery acquired in the first period is less than or equal to the trigger threshold, S113 may be continued.
In some alternative embodiments, as shown in fig. 8, S114 may include S1141 and S1142. S21 may include S213.
S1141, if the state value is greater than the trigger threshold, acquiring the state value of the battery according to a second period and continuously presetting the duration;
s1142, obtaining a maximum state value in a plurality of state values of the battery within a preset duration;
s213, determining a treatment scheme of the battery according to the comparison result of the maximum state value and the reference threshold value.
After the collision occurs, the state value of the battery may not reach the maximum value immediately, but may take a certain period of time to reach the maximum value. The greater the state value of the battery obtained, the greater the severity of the battery being impacted. In the embodiment of the application, the prediction accuracy of the battery state can be improved by comparing the maximum state value in a plurality of state values of the battery within the preset time period with the reference threshold.
For example, if the state value of the battery acquired according to the first period is greater than the trigger threshold, a software interrupt may be triggered to acquire the state value of the battery according to the second period. For example, a buffer space may be opened up in the interrupt, a plurality of state values of the battery collected according to the second period and accumulated for a preset period after the collision occurs are continuously stored, the maximum state value is uploaded to the application layer for processing, and then the maximum state value is compared with a reference threshold.
Taking the state value as an acceleration value as an example, the acceleration values in three directions (a first direction X, a second direction Y and a third direction Z) can be collected in a first period of 10ms, the collected acceleration values are compared with a trigger threshold, if the collected values are smaller than the trigger threshold, a new round of sampling is continuously carried out according to the first period, and the old values are covered by the new sampling values.
If the acceleration value acquired at a certain moment is larger than 15g, triggering a software interrupt, setting the sampling period of the acceleration to be a second period of 1ms in the interrupt, and continuously acquiring for 100ms.
A buffer space can be opened up in the interrupt, acceleration values in three directions acquired after collision are continuously stored, the maximum value of the acceleration values in the three directions within 100ms is regarded as the maximum acceleration value received by the battery during collision, and the maximum acceleration value is uploaded to an application layer for processing.
The application layer compares the maximum acceleration value suffered by the battery in collision with a reference threshold value, and determines a treatment scheme for the battery according to the comparison result.
It should be noted that, the application scenario described in the foregoing embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application, and as a person of ordinary skill in the art can know, with the appearance of a new application scenario, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.
