[0035] The embodiments disclosed in the present invention will be described in more detail below with reference to the accompanying drawings. Although certain embodiments disclosed in the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and embodiments disclosed in the present invention are only for exemplary purposes and are not intended to limit the scope of protection disclosed in the present invention.

[0036] In the description of the embodiments disclosed in the present invention, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0037] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1, an embodiment of a vehicle battery preheating method in an embodiment of the present invention comprises:

[0038] 101. Obtain the arrival time of the preset weather and the user's car use time;

[0039] 102. Determine the duration of a vehicle battery being in a low temperature state according to the arrival time of the preset weather and the vehicle usage time, wherein the low temperature state is a state in which the temperature is lower than a preset temperature threshold.

[0040] 103. Preheat the vehicle battery according to the length of time the vehicle battery is in a low temperature state.

[0041] Specifically, the preset weather is cold wave / cold current and the like.

[0042] The above scheme determines the length of time the vehicle battery is in a low-temperature state, thereby facilitating an estimate of whether the vehicle battery will be frozen through before the next use of the vehicle, and preheating the vehicle battery according to the length of time the vehicle battery is in a low-temperature state, which can effectively prevent the vehicle battery from being frozen through when cold weather arrives.

[0043] In some embodiments, obtaining the arrival time of the preset weather includes: obtaining the vehicle position corresponding to the vehicle battery; and obtaining the arrival time of the preset weather according to the vehicle position. By obtaining the vehicle position, it is convenient to more accurately understand the weather conditions in different locations, so as to prepare for subsequent preheating.

[0044] Furthermore, obtaining the arrival time of the preset weather according to the vehicle position includes: obtaining the weather forecast information corresponding to the vehicle position; obtaining the arrival time of the preset weather from the weather forecast information. The weather forecast information contains weather information and the corresponding arrival time, as well as the duration of the weather. Therefore, through the weather forecast information of different locations, it is possible to determine whether there is a preset weather, such as a cold wave, and at the same time, the arrival time and duration of a certain weather can be obtained, so that the temperature state of the vehicle can be determined by using the preset weather.

[0045] In some embodiments, obtaining the vehicle usage time of a user includes: obtaining the vehicle position corresponding to the vehicle battery; and obtaining the vehicle usage time of the user according to the vehicle position. Specifically, after obtaining the vehicle position, a table lookup operation is performed in a preset vehicle usage time database to obtain the vehicle usage time corresponding to different vehicle positions. The vehicle usage time database stores a mapping relationship between the vehicle number, the user, the vehicle position, and the vehicle usage time of the user.

[0046] By adopting the above scheme, a vehicle usage time database can be prepared in advance. When preheating the vehicle battery, as long as the vehicle location is obtained, the user's vehicle usage time can be understood, which makes it easy to determine the length of time the vehicle battery is in a low temperature state based on the vehicle usage time.

[0047] In some embodiments, determining the duration of the vehicle battery being in a low temperature state according to the arrival time of the preset weather and the vehicle use time includes: determining the duration between the vehicle use time and the arrival time of the preset weather as the duration of the vehicle battery being in a low temperature state. For example, if the arrival time of the preset weather is 23:00, the user's vehicle use time is 07:00, and there are 8 hours between 23:00 and 07:00, then the duration of the vehicle battery being in a low temperature state is determined to be 8 hours.

[0048] In some embodiments, preheating the vehicle battery according to the duration of the vehicle battery being in a low temperature state includes: preheating the vehicle battery when the duration of the vehicle battery being in a low temperature state reaches a set time threshold. In this way, it is easy to determine whether the vehicle battery will be frozen through, thereby facilitating the preheating of the vehicle battery to prevent the vehicle battery from being frozen through.

[0049] Optionally, in some other embodiments, obtaining the arrival time of preset weather includes:

[0050] Combine historical weather conditions to conduct big data analysis and obtain the arrival time of preset weather.

[0051] Specifically, historical weather forecast information for a preset time period and actual weather information corresponding to the preset time period are collected. The historical weather forecast information includes historical weather information and the corresponding arrival time, as well as the duration of historical weather corresponding to the preset location information. The actual weather information corresponding to the preset time period includes actual weather information and the corresponding arrival time, as well as the duration of actual weather corresponding to the preset location information. The historical weather forecast information for the preset time period is used as a training sample for the forecast model, and the actual weather information corresponding to the preset time period is used as a sample label. The forecast model sample is trained using a neural network model to obtain a weather forecast model. When obtaining the arrival time of the preset weather, the current weather forecast information is collected and input into the weather forecast model to obtain the weather information and the corresponding arrival time, as well as the duration of the weather. The weather information obtained includes weather such as cold currents / cold waves.

[0052] Optionally, in other embodiments, obtaining the user's car usage time includes: using the user's car usage habits to predict the user's car usage time.

[0053] Specifically, the user's car usage habits include: the driving trajectory and the departure time corresponding to the starting position of the trajectory. In some embodiments, the user's work and home locations and the corresponding departure times are obtained, and when the electric vehicle is at the starting position of the historical driving trajectory, the corresponding departure time can be matched as the predicted user's car usage time.

[0054] Optionally, in some other embodiments, obtaining the user's car usage time includes:

[0055] Get the user's car use time set by the user, get the distance adjustment time corresponding to the preset weather, and predict the user's car use time based on the distance adjustment time and the user's car use time.

[0056] The user's car use time is the car use time input by the user through a user terminal such as a smart phone, a tablet computer, or a computer. The user may also input information such as the vehicle number through the user terminal. Optionally, the user's car use time and / or the vehicle number input by the user is stored in a user's car use time database to obtain a user's car use time database storing a mapping relationship between the vehicle number, the user, and the user's car use time.

[0057] Furthermore, obtaining the route adjustment time corresponding to the preset weather conditions includes:

[0058] After obtaining the weather forecast information corresponding to the vehicle location, the method further includes: sending the weather forecast information to the user terminal, triggering the user terminal to feedback the reading status of the weather forecast information. The reading status includes the reaction time of viewing the weather forecast, the stay time spent viewing the weather forecast, and the number of times the weather forecast is viewed. The distance adjustment time corresponding to the preset weather is obtained according to the above stay time, reaction time and number of times.

[0059] Specifically, the electric vehicle or server sends weather forecast information to the user terminal in the form of email, T-shirt, or APP notification. After receiving the weather forecast information sent by the electric vehicle or server, the user terminal records the time when the user terminal receives the weather forecast information, the time when the weather forecast information is viewed for the first time, and the number of times the weather forecast information is clicked. The duration from when the weather forecast information is clicked to when it is closed is determined as the dwell time for viewing the weather forecast information. If the weather forecast information is clicked multiple times, the sum of the dwell time for each click to view the weather forecast information is determined as the dwell time for viewing the weather forecast information. Specifically, the time when the weather forecast information is clicked for the first time is determined as the time when the user views the weather forecast for the first time. Specifically, the user's reaction time for viewing the weather forecast is: the difference between the time when the user terminal receives the weather forecast and the time when the weather forecast is viewed for the first time.

[0060] Specifically, obtaining the route adjustment time corresponding to the preset weather conditions according to the above-mentioned stay time, reaction time and number of times includes:

[0061] calculate Get the route adjustment time corresponding to the preset weather. Among them, T ad Adjust the time for the route corresponding to the preset weather. is the preset first adjustment coefficient, T re The reaction time for checking the weather forecast, T set1 is the preset first time length value, β is the preset second adjustment coefficient, T stay The stay time to check the weather forecast, F read is the number of times you check the weather forecast, T set2 is the preset second time length value, T set1 >0, T set2 >0.

[0062] Specifically, Wherein, A is the preset third adjustment coefficient, A>1, α is the preset fourth adjustment coefficient, α>1, T y1 is the preset first time length threshold, T y2 is the preset second time length threshold, F y is the preset number threshold, T y3 is the preset third time length threshold, T y4 is the preset fourth time length threshold, δ is the preset fifth adjustment coefficient, 0<δ<1. y1 , T y2 、F y , T y3 , T y4 Both are greater than 0.

[0063] Specifically, by calculating T c =T yh -T ad Get the user's car usage time. Among them, T ad Adjust the time for the journey, T yh is the user’s car usage time, T c The user's car usage time.

[0064] The above scheme reflects the impact of weather forecast on user travel by checking the reaction time of weather forecast, the stay time spent on checking weather forecast, and the number of times of checking weather forecast, and then estimates the time that the user may need to adjust on the travel route, and then adjusts the estimate of the user's car use time, so as to facilitate more accurate preheating of the battery of the electric vehicle. When the reaction time of checking weather forecast, the stay time spent on checking weather forecast, and the number of times of checking weather forecast are all less than the preset threshold, it is convenient to reflect that the user quickly checks weather forecast information. When the reaction time of checking weather forecast and the stay time spent on checking weather forecast are greater than the preset threshold, and the number of times of checking weather forecast are less than the preset threshold, it is convenient to reflect that the user checks weather forecast information very carefully and pays more attention to the route and travel time, so the impact of stay time on adjustment time is increased. In other cases, the impact of stay time on adjustment time is reduced. The acquisition method of the second adjustment coefficient corresponding to the stay time spent on checking weather forecast can estimate the impact of weather forecast on user adjustment of travel time according to different behaviors of users checking weather forecast information. This will enable a more accurate estimate of the user's vehicle usage time, thereby better determining the timing for preheating the vehicle battery.

[0065] Optionally, in some embodiments, preheating the vehicle battery according to the length of time the vehicle battery is in a low temperature state includes:

[0066] When the duration of the vehicle battery being in the low temperature state reaches a set time threshold, a preheating start time is determined, and when the preheating start time is reached, the vehicle battery is preheated.

[0067] Specifically, by calculating Determine the preheating start time. Among them, T start is the warm-up start time, T L is the expected weather time. set3 is the preset third time length value, T set3 >0. The above solution facilitates timely preheating after the arrival of cold weather, which can effectively prevent the vehicle battery from freezing. In addition, the longer the mileage adjustment time, the earlier the preheating starts. When the user needs to use the vehicle in advance due to weather reasons, the battery temperature can also be guaranteed to be within the appropriate range.

[0068] like Figure 2As shown, an embodiment of a vehicle battery preheating device in an embodiment of the present invention includes an acquisition module 201, a determination module 202 and a preheating module 203.

The low temperature state is a state where the temperature is lower than a preset temperature threshold. The preheating module 203 is configured to preheat the vehicle battery according to the duration of the vehicle battery being in a low temperature state.

[0069] Furthermore, the acquisition module 201 acquires the arrival time of the preset weather by the following methods: acquiring the vehicle position corresponding to the vehicle battery; and acquiring the arrival time of the preset weather according to the vehicle position.

[0070] Furthermore, the acquisition module 201 acquires the arrival time of the preset weather according to the vehicle position in the following manner: acquiring weather forecast information corresponding to the vehicle position; and acquiring the arrival time of the preset weather from the weather forecast information.

[0071] Furthermore, the acquisition module 201 acquires the user's vehicle usage time in the following manner: acquiring the vehicle position corresponding to the vehicle battery; and acquiring the user's vehicle usage time according to the vehicle position.

[0072] Furthermore, the determination module 202 determines the duration that the vehicle battery is in a low temperature state according to the arrival time of the preset weather and the vehicle usage time in the following manner: the duration between the vehicle usage time and the arrival time of the preset weather is determined as the duration that the vehicle battery is in a low temperature state.

[0073] Further, the preheating module 203 preheats the vehicle battery according to the duration that the vehicle battery is in the low temperature state in the following manner: when the duration that the vehicle battery is in the low temperature state reaches a set time threshold, the vehicle battery is preheated.
