Detailed ways

The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

Fig. 1 is a flow chart of a temperature management method provided by an exemplary embodiment of the present invention. The temperature management method is applied to a substation where multiple temperature detection devices are dispersedly deployed, and the number and density of temperature detection devices are deployed. It can be set by itself according to the actual situation. The deployment position of the temperature detection equipment can include, but is not limited to, the charging compartment of the power station, the battery rack, the charger, the electrical connector, the cable, etc. The type of temperature detection equipment can be set according to the actual situation. In this embodiment, the temperature detection equipment can be preferably an optical fiber sensor. The optical fiber sensor is small in size and low in cost. It is suitable for a large number of arrangements in the power exchange station and is convenient to be placed in a narrow position in the power exchange station. Moreover, the optical fiber sensor is not easy to affect the battery or charging equipment, and has high safety. Of course, in other embodiments, a device may also be used to implement temperature detection, which will not be repeated here.

Referring to Figure 1, the temperature management method includes the following steps:

Step 101, acquiring temperature data collected by multiple temperature detection devices.

In one embodiment, the temperature data is acquired by the temperature detection device according to a preset cycle, without manual intervention, and has a high degree of automation. The preset cycle can be set according to the actual situation. It is understandable that the smaller the cycle is set, the more accurately the obtained temperature data can reflect the current temperature state of the substation, and the more accurate the temperature management is.

In one embodiment, the temperature data can be obtained when a temperature management application is received, that is, temperature management is performed only when there is a need, and no need to perform temperature management when there is no need, so as to avoid unnecessary waste of computing resources.

Step 102, constructing a temperature field of the battery swapping station according to the temperature data.

In one embodiment, when constructing the temperature field, first establish the spatial coordinate system in the space of the power station, and obtain the space coordinates of each temperature detection device, and then construct the space of the power station according to the temperature data of each temperature detection device and the corresponding space coordinates temperature field inside.

Fig. 2 is a schematic diagram of the temperature field constructed in step 102 provided by an exemplary embodiment of the present invention. The temperature data collected by the temperature detection device is used as the temperature of the position where the temperature detection device is located in the temperature field. For the position where the temperature detection device is not deployed, then The interpolation smoothing algorithm is used to obtain the temperature of each position of the power station, so as to obtain the temperature field image shown in Figure 2.

Step 103, performing temperature management on the substation based on the temperature field.

In one embodiment, the step of performing temperature management on the substation based on the temperature field includes: calculating the temperature at each location in the substation based on the temperature field, and determining the region where the temperature falls within a preset temperature range as an abnormal temperature region.

Among them, the preset temperature range can be set according to the actual situation. Generally, it is the temperature range in which the equipment can guarantee normal operation, and can monitor the situation of the temperature being too high or too low. For example, the preset temperature range can be 20°C to 50°C. When the temperature in a certain area in the power station is greater than or equal to 50°C, it means that the temperature in this area is too high, and there may be a risk of serious equipment heating or even catching fire. Then determine this area for the abnormal temperature region. In other optional embodiments, for a substation located in a low-temperature area in winter, the preset temperature range can also be set to 5°C to 40°C. When the temperature in a certain area in the substation is less than or equal to 5°C, it means that the area If the temperature is too low, and the charging effect of the battery is poor and the efficiency is low in this area, then this area is determined to be an abnormal temperature area.

In one embodiment, if there is an abnormal temperature area, an abnormal temperature alarm is generated to prompt operation and maintenance personnel to check the abnormal temperature area in time to avoid equipment failure caused by fire or overheating. Abnormal temperature alarm can be realized by but not limited to SMS, mail, telephone, sound and light alarm, etc.

In one embodiment, the temperature management method further includes: creating a temperature display interface of the power exchange station, and displaying the abnormal temperature area differently from other areas in the temperature display interface of the power exchange station. Among them, the other regions are regions whose temperature does not fall within the preset temperature range, that is, the normal temperature region.

For example, the abnormal temperature area can be highlighted, or displayed in a high-contrast, high-saturation color, etc., to distinguish the normal temperature area, and to distinguish between the normal temperature area and the abnormal temperature area, making the temperature situation of the power station more intuitive and easy to operate. The maintenance personnel can detect the temperature abnormality in time and deal with the abnormality in time.

In one embodiment, the step of creating the temperature display interface of the power exchange station includes: establishing a three-dimensional space model inside the power exchange station, and superimposing and displaying the temperature field and the three-dimensional space model to obtain the temperature interface of the power exchange station. By superimposing the temperature field and the three-dimensional model of the substation space, the corresponding relationship between the temperature field and the space in the substation can be intuitively reflected, and it is convenient for the operation and maintenance personnel to locate the abnormal temperature area.

In one embodiment, the temperature management of the substation is implemented through the temperature control equipment in the substation. Specifically, when there is an abnormal temperature area in the temperature field, the temperature control equipment is controlled to adjust the temperature of the abnormal temperature area.

Among them, temperature control equipment includes air conditioners, exhaust equipment, etc. Ways to control temperature control equipment to adjust the temperature of abnormal temperature areas may include, but are not limited to: adjusting the number of temperature control equipment put into operation, for example, when the temperature in a certain area in the power station is too high, increase air conditioning and/or exhaust The number of equipment in operation, that is, increasing the number of air conditioners and/or exhaust equipment activated, so that multiple air conditioners and/or exhaust equipment can cool down the abnormal temperature area at the same time, so as to achieve the purpose of rapid cooling; and/or, adjust the temperature control The operating power of the equipment, for example, when the temperature in a certain area in the substation is too high, increase the operating power of the air conditioner to operate at a lower temperature to achieve the purpose of rapid cooling.

In one embodiment, the method further includes adjusting the layout of the power exchange station, specifically, acquiring temperature field record data of the power exchange station within a preset time range, and adjusting the layout of the power exchange station according to the temperature field record data.

Wherein, the preset time range can be set according to the actual situation, for example, one month or one year forward from the current time, which is not particularly limited in this embodiment of the present invention.

When adjusting the layout of the power station, the temperature distribution in the power station can be determined according to the temperature field record data, and the number and/or location of equipment in the power station can be adjusted based on the temperature distribution. The adjustment of the layout of the substation can be aimed at the substation that obtains the recorded data of the temperature field, that is, the substation can be rebuilt according to the temperature distribution. In addition, the temperature distribution of the substation can be used to adjust the layout of subsequent substations of the same type or similar types. Provide optimization reference.

Wherein, the power station equipment includes at least one of charging equipment, temperature detection equipment and temperature control equipment.

For example, for charging equipment, if the temperature is too high or too low, it is not conducive to the operation of the charging equipment. If it is determined according to the temperature field record data that a certain area in the swap station is often determined to be an abnormal temperature area, then all the areas in this area will be controlled. Or part of the charging equipment stops running, or generates a deployment strategy for the reference of the operation and maintenance personnel to adjust the layout of the equipment in the power station. Remove the charging equipment at this location, so as to avoid abnormal temperature from affecting the operation of the charging equipment, or even cause damage to the charging equipment, and also prevent the heat generated by the operation of the charging equipment from further increasing the temperature in this area when the temperature of the swap station is too high. On the other hand, in order to provide users with sufficient battery replacement services, it is also possible to increase the number of charging equipment put into operation in the normal temperature region.

For temperature detection equipment, if it is determined according to the recorded data of the temperature field that a certain area in the substation is often identified as a temperature abnormal area, in order to accurately locate the abnormality, the number of temperature detection equipment in this area can be increased to achieve more accurate detection Location of abnormal temperature regions. For areas that are not or rarely identified as temperature abnormal areas, the number of temperature detection devices in this area can be reduced to reduce operation and maintenance costs.

In the embodiment of the present invention, by constructing the temperature field of the swap station, and managing the temperature of the swap station based on the temperature field, since the temperature field can accurately reflect the temperature conditions in each area of the swap station, the temperature at each position in the swap station can be realized. Effective monitoring keeps the temperature in each area of the power station within an appropriate range, provides a better operating environment for the equipment, and improves the safety of the power station operation.
