It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Fig. 1 illustrates a condensation detection method of a battery box of a vehicle of the present disclosure, which may include the steps of:
step S101, if it is determined that the temperature-related information in the battery box meets the preset condition, detecting a variation of the water content of the gas in the preset volume in the battery box in the preset detection period.
In this embodiment, the execution body that executes the condensation detection method of the battery box of the vehicle may detect the amount of change in the water content of the gas of the preset volume in the battery box in the case where it is determined that the temperature-related information in the battery box satisfies the preset condition.
Specifically, the execution body detects the water content variation in a preset detection period, and the obtained detection result is the water content variation from the beginning time to the last time of the preset detection period. The preset detection period may be, for example, a preset duration, such as 10 minutes.
The preset volume may be various, for example, the preset volume may be a volume of gas inside the battery case. In some application scenarios, the gas volume may be calculated from a three-dimensional model. Alternatively, the preset volume may be a unit volume inside the battery case, and specifically, the unit volume may be 1 cubic meter or 1 cubic centimeter, or the like. The gas in the present disclosure is typically air.
The execution body may determine the amount of change in the water content in various ways. For example, the execution body may acquire a detection result of the water content in the battery box by a water content detector (i.e., a water content detection table) disposed in the battery box. The water content is saturatedThe water vapor content in g/m 3 . Then, the execution body may input the detection result to a model and obtain the amount of change in the water content output from the model. Specifically, the model is a pre-trained deep neural network, and the water content variation can be predicted through the detection result of the water content detector.
Step S102, detecting the maximum condensation quality of the position which is preset in the battery box and easy to condense in the preset detection period.
In this embodiment, the executing body may detect the maximum condensation quality of the easily condensation position in the battery box in a preset detection period. The dew-prone position refers to a position where dew is easily generated, and the position is a preset or detected position in advance.
In some application scenarios, the preset easy-condensation position may be at least one of the following: the battery cell, the electric box, the inner side of the box cover and the liquid cooling plate.
The execution body may detect the maximum condensation mass in various ways. For example, a detector for water content may be provided at a position where water is easily condensed in the battery box, and the execution body may acquire a detection result of the detector, and obtain a water content of a specified volume as the maximum condensation mass from the detection result. For example, the water content is 1000X g/m 3 Designated volume is 2dm 3 . The execution subject can determine 2dm 3 Namely 2/1000m 3 The maximum condensation mass of the preset easy condensation position is 1000Xg/m 3 ×2/1000m 3 = X g is the maximum condensation mass at the preset easy-condensation position.
And step S103, determining the maximum condensation mass in the battery box according to the water content variation and the maximum condensation mass.
In this embodiment, the execution body may determine the maximum condensation mass in the battery box according to the water content variation obtained in step 101 and the maximum condensation mass obtained in step S102 in various manners. For example, the execution body may input the water content change and the maximum condensation mass into a preset formula or model, and obtain the maximum condensation mass in the battery box output by the formula or model.
And step S104, outputting alarm information according to the maximum condensation mass in the battery box.
In this embodiment, the executing body may output the alarm information according to the maximum condensation quality in the battery box in various manners. For example, the executing body may send the maximum condensation quality to a preset electronic device, and output alarm information when the alarm indication information fed back by the electronic device is yes.
The embodiment can accurately determine the maximum condensation quality in the battery box by detecting the maximum condensation quality of the water content change and the condensation position in the battery box, thereby accurately determining the alarm time about condensation and avoiding the loss to the battery box due to the excessively serious condensation condition.
Fig. 2 illustrates a condensation detection method of a battery box of a vehicle according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
step S201, if it is determined that the temperature related information in the battery box meets the preset condition, detecting a variation of the water content of the gas in the preset volume in the battery box in the preset detection period.
Step S202, detecting the maximum condensation quality of the position which is preset in the battery box and easy to condense in the preset detection period.
And step S203, determining the larger of the water content variation and the maximum condensation mass as the maximum condensation mass in the battery box.
In this embodiment, the execution body may compare the amount of change in the water content obtained in step S201 with the maximum condensation mass obtained in step S202, and use the larger of the comparison results as the maximum condensation mass in the battery box.
And step S204, outputting alarm information according to the maximum condensation mass in the battery box.
In this embodiment, the above-mentioned amount of change in water content and the maximum condensation mass at the condensation site are all theoretically possible amounts of condensation. The embodiment takes larger values of the two, and can accurately determine the maximum condensation mass possibly reached in the battery box, so that the problem that the determined condensation mass is smaller than the actual condensed condensation mass can be avoided, and the alarm accuracy is improved.
In some optional implementations of any of the embodiments of the disclosure, the temperature-related information includes a preset temperature difference value and a temperature change rate, the preset temperature difference value is a temperature difference value between air in the battery box and the easy-condensation position, and the temperature change rate is a temperature change rate of air in the battery box; the preset conditions include at least one of the following: the preset temperature difference value is larger than a temperature difference value threshold value, and the temperature change rate is larger than a change rate threshold value; the preset temperature difference is determined through a first mapping relation, the first mapping relation is used for indicating the corresponding relation between the temperature, the humidity and the preset temperature difference, the temperature change rate is determined through a second mapping relation, and the second mapping relation is used for indicating the corresponding relation between the temperature, the humidity and the temperature change rate.
In these alternative implementations, the preset condition may refer to the preset temperature difference corresponding to the location of the easy condensation being greater than a temperature difference threshold, and the preset condition may also refer to the rate of change of temperature being greater than a rate of change threshold.
In addition, the temperature change corresponding to both the preset temperature difference and the temperature change rate is a temperature drop.
The executing body or other electronic devices may acquire the temperature and the humidity inside the battery box, and query a preset temperature difference value corresponding to the temperature and the humidity in the first mapping relationship. The executing body or other electronic devices may further query the temperature change rate corresponding to the temperature and the humidity in the second mapping relationship.
The executing body or other electronic devices may perform experiments in advance to determine preset temperature differences and temperature change rates corresponding to different temperatures and humidities, so as to generate a first mapping relationship and a second mapping relationship.
The realization modes can take local temperature change of the easy condensation position as a condensation detection condition or overall temperature change in the battery box as a condensation detection condition, so that whether the battery box needs condensation detection or not can be determined from different angles, and the accuracy of determining the condensation detection time is improved.
In some optional implementations of any of the embodiments of the disclosure, the preset detection period includes a first time and a last time; the detection of the water content variation of the gas with the preset volume in the battery box in the preset detection period comprises the following steps: determining the water content of the air in the battery box at a first temperature as a first water content, wherein the first temperature is the temperature in the battery box corresponding to the first moment; determining the water content of the air in the battery box at a second temperature as a second water content, wherein the second temperature is the temperature in the battery box corresponding to the last moment; and determining the difference value of the first water content and the second water content as the water content variation of the preset volume of gas in the battery box.
In these implementations, the first and last moments of the preset detection period may be T respectively 1 And T 2 . At T 1 To T 2 At the moment, the change m of the water content of the preset volume of gas (such as the same volume V) in the battery box along with the temperature 1 Can be expressed as:
m 1 ＝V×A 1 (t 1 )-V×A 2 (t 2 )，
wherein V represents a preset volume of air in the battery box (such as the total volume of air in the battery box), t 1 Representing T 1 Temperature in battery box at moment, t 2 Representing T 2 Temperature in the battery box at the moment. A is that 1 (t 1 ) At t 1 Saturated water vapor content at temperature, A 2 (t 2 ) At t 2 Saturated water vapor content at temperature. Specifically, A 1 (t 1 ) And A 2 (t 2 ) Can be obtained by looking up a table of temperatures in a temperature-moisture correspondence table. V×a may represent the water content, i.e., the condensation amount, obtained when all of the water vapor in the air of volume V becomes condensed. T is as described above 1 And t 2 The temperature can be detected by a thermometer arranged in the battery box.
The implementation modes can accurately acquire the change rate of the water content through the water content at different moments.
In some optional implementations of any of the embodiments of the disclosure, the preset detection period includes a first time and a last time; the detection is in the preset detection period, the maximum condensation mass of the position which is easy to condense is preset in the battery box, and the detection comprises the following steps: determining the water content of the air in the battery box at a first temperature as a first water content, wherein the first temperature is the temperature in the battery box corresponding to the first moment; determining the water content of the air in the battery box at a third temperature as a third water content, wherein the third temperature corresponds to the last moment and is the temperature of the preset easy-condensation position; and determining the difference value of the first water content and the third water content as the maximum condensation mass of the preset easy-condensation position.
In these alternative implementations, the execution body may determine, not only the first water content corresponding to the first temperature for the whole battery box, but also the water content of the easy-condensation location, that is, the third water content, at the third temperature.
Then, the executing body may determine the difference between the first water content and the third water content as a maximum condensation mass of the preset easy-condensation position:
m 2 ＝V×A 1 (t 1 )-V×A 3 (t 3 )，
wherein t is 3 Indicating that the preset easy condensation position is at T 2 Temperature at time. A is that 3 (t 3 ) At t 3 Saturated water vapor content at the site of easy condensation at temperature. T is as described above 3 The temperature detection can be performed by a thermometer arranged at a position easy to condense in the battery box.
The implementation modes can determine that if all water vapor in the volume V in the battery box is condensed at the position easy to condense, the condensation mass of the position easy to condense after the whole preset detection period is passed, so that the condensation of the position easy to condense can be estimated to the greatest extent, and the problem of missing of alarm opportunity caused by underestimating the condensation mass of the position easy to condense is avoided.
In some optional implementations of any of the embodiments of the disclosure, outputting the alarm information according to the maximum condensation quality in the battery box includes: determining the size relation between the maximum condensation mass in the battery box and a condensation mass threshold; and outputting alarm information according to the size relation.
In these alternative implementations, the executing body may determine a size relationship between the maximum condensation mass in the battery box and the condensation mass threshold, and output alarm information according to the size relationship in various manners. For example, the execution subject may directly input the magnitude relation to a specified model and obtain information output from the model. This information is used to indicate whether an alarm is given, and in the case of an alarm.
These alternative implementations can accurately determine whether the maximum condensation quality meets the alarm condition by the condensation quality threshold.
In some optional application scenarios of these implementations, the outputting alarm information according to the size relationship may include: if the maximum condensation mass in the battery box is greater than or equal to the condensation mass threshold, outputting alarm information in real time; if the maximum condensation mass in the battery box is smaller than the condensation mass threshold, determining the maximum condensation mass in the battery box in another detection period after the preset detection period; and determining the sum of the maximum condensation masses until the sum is greater than or equal to the condensation mass threshold value, and outputting alarm information.
In these application scenarios, the execution body may directly output the alarm information in real time under the condition that the maximum condensation quality is large. And under the condition that the maximum condensation mass is smaller, continuously determining the maximum condensation mass of the next detection period, thereby determining the accumulated value of the maximum condensation mass. The cumulative value is the sum of the maximum condensation masses. Until the accumulated value reaches the condensation quality threshold, alarm information can be output.
The application scenes can output alarm information according to the conditions under the condition that the size relation between the maximum condensation quality and the condensation quality threshold is different, so that the alarm accuracy is improved.
