[0057] At present, with the development of electronic technology, new energy vehicles powered by batteries are gradually being promoted and applied. Such new energy vehicles face many challenges in operation under low temperature conditions, especially the performance of power batteries will be significantly affected. In order to ensure the normal operation and performance of the vehicle under low temperature conditions, the battery is usually heated before or during driving.

[0058] In the related art, when heating the battery, the heating is stopped after the battery cell reaches a preset temperature threshold. This process consumes the battery's own energy. In actual applications, it is found that this strategy is often difficult to meet the actual needs of users. For example, if the heating temperature threshold is set too high, the vehicle's endurance will be affected; or if the heating temperature threshold is set too low, the battery performance is limited and cannot provide a good driving experience, which has the problem of low practicality.

[0059] In view of this, a method for controlling battery heating of a new energy vehicle is provided in an embodiment of the present application. The method obtains the user's travel plan information and determines the driving mode selected by the user; wherein the travel plan information includes information of the departure place and the destination; determines the target route according to the departure place and the destination, and determines the estimated driving time according to the target route; calculates the height difference between the departure place and the destination, obtains the proportion information of various road conditions on the target route, and determines the driving self-heat according to the height difference, the proportion information and the estimated driving time; detects the ambient temperature and battery cell temperature of the new energy vehicle, and determines the target heating temperature according to the ambient temperature, the battery cell temperature, the driving self-heat and the driving mode; and heats the battery of the new energy vehicle according to the target heating temperature. The method can determine the appropriate heating temperature according to the environment of the new energy vehicle and the user's travel plan, realizes the heating of the battery of the new energy vehicle, and can take into account the vehicle's endurance and driving performance, and is more practical.

[0060] Next, the implementation environment of the new energy vehicle battery heating control method provided in the embodiment of the present application is first introduced. Figure 1 , Figure 1 A schematic diagram of an implementation environment of a new energy vehicle battery heating control method is provided, wherein the software and hardware components of the implementation environment mainly include a terminal device 110 and a server 120, and the terminal device 110 is in communication connection with the server 120. The new energy vehicle battery heating control method can be configured on the terminal device 110 side, or the new energy vehicle battery heating control can be realized through the interaction between the terminal device 110 and the server 120.

[0061] Specifically, in the embodiment of the present application, the terminal device 110 may include but is not limited to any one or more of a smart watch, a smart phone, a computer, a personal digital assistant (PDA), an intelligent voice interaction device, a smart home appliance or a vehicle-mounted terminal. The server 120 may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The terminal device 110 and the server 120 may establish a communication connection through a wireless network or a wired network, which uses standard communication technology and / or protocols. The network may be set to the Internet or any other network, such as but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or a virtual private network.

[0062] Of course, it is understandable that Figure 1 The implementation environment in the embodiment of the present application is only an optional application scenario of the new energy vehicle battery heating control method provided in the embodiment of the present application, and the actual application is not fixed to Figure 1 The hardware and software environment shown below. Figure 1 The implementation environment shown is used to explain in detail the new energy vehicle battery heating control method provided in the embodiments of the present application.

[0063] Please refer to Figure 2 , Figure 2 This is a flow chart of a new energy vehicle battery heating control method provided in an embodiment of the present application, referring to Figure 2 The present application provides a new energy vehicle battery heating control method including but not limited to:

[0064] Step 210: Obtain the user's travel plan information and determine the driving mode selected by the user; wherein the travel plan information includes information of the departure place and the destination;

[0065] Step 220: determining a target route according to the departure place and the destination, and determining an estimated driving time according to the target route;

[0066] Step 230: Calculate the height difference between the departure point and the destination, obtain the proportion information of various road conditions on the target route, and determine the driving spontaneous heat according to the height difference, the proportion information and the estimated driving time;

[0067] Step 240, detecting the ambient temperature and the battery core temperature of the new energy vehicle, and determining the target heating temperature according to the ambient temperature, the battery core temperature, the spontaneous heat generated during driving, and the driving mode;

[0068] Step 250: heating the battery of the new energy vehicle according to the target heating temperature.

[0069] In an embodiment of the present application, a new energy vehicle battery heating control method is provided. The method can determine a suitable heating temperature according to the environment in which the new energy vehicle is located and combined with the user's travel plan, thereby achieving battery heating for the new energy vehicle, taking into account the vehicle's endurance and driving performance, and having better practicality.

[0070] Specifically, the new energy vehicle battery heating control method provided in the embodiment of the present application can first obtain the user's travel plan information when heating the battery of the new energy vehicle. Here, the travel plan information may include information about the departure place and the destination. In addition, in the embodiment of the present application, the driving mode selected by the user can also be obtained. Exemplarily, in some embodiments, the determining of the driving mode selected by the user includes:

[0071] Displaying preset optional modes to the user; wherein the preset optional modes include a powered mode, a normal mode, and an endurance mode;

[0072] The driving mode selected by the user is determined according to the user's selection operation on the preset optional mode.

[0073] In the embodiment of the present application, when determining the driving mode selected by the user, the preset optional mode can be displayed to the user, and the types of preset optional modes here can include power mode, normal mode and endurance mode. Among them, the power mode is a mode of high-performance output of new energy vehicles. In the power mode, the throttle response is more sensitive, and the driver can feel faster acceleration and more direct power transmission. Relatively speaking, due to the high power output, the energy consumption in the power mode is higher and the cruising range is relatively short. In the normal mode, the performance and energy consumption of the vehicle reach a balance, which not only ensures sufficient power output, but also takes into account energy efficiency. Moreover, in this mode, the throttle response is moderate, the driving experience is smoother and more comfortable, and it is suitable for common scenes such as urban commuting and daily driving. It is the default mode used by most users. Compared with the power mode, the energy consumption in the normal mode is lower, but slightly higher than the endurance mode. In the endurance mode, the vehicle's control system optimizes various parameters to maximize the cruising range, the throttle response becomes relatively slow, and the acceleration performance is relatively weak.

[0074] Of course, it can be understood that in the embodiments of the present application, the types of preset optional modes can be flexibly set and adjusted according to actual needs, and the present application does not impose any restrictions on this.

[0075] In an embodiment of the present application, after the preset optional modes are displayed to the user, the user can select one of the modes as the selected driving mode. In some cases, the user may not make a selection within the time limit. In this case, the driving mode can be determined as a predetermined type. Specifically, for example, in some embodiments, after the preset optional modes are displayed, the cumulative display time of the preset optional modes can be monitored and compared with a preset preset time threshold. If the cumulative display time has not reached the preset time threshold, the monitoring can continue. If the cumulative display time reaches the preset time threshold and the user has not made a selection at this time, the normal mode can be determined as the driving mode selected by the user.

[0076] In the embodiment of the present application, after obtaining the user's travel plan information, the target route can be determined based on the departure place and destination. Specifically, in the embodiment of the present application, a third-party map service (such as Google Maps API, Amap API, etc.) can be used to perform address resolution and path planning on the departure place and destination, so as to determine the target route. In some cases, when determining the target route, multiple alternative results can also be provided for the user to choose from.

[0077] Exemplarily, in some embodiments, determining the target route according to the departure place and the destination includes:

[0078] Determine a number of alternative routes based on the departure place and the destination;

[0079] presenting the alternative route to the user;

[0080] The target route is determined according to the user's selection operation on the alternative routes.

[0081] In an embodiment of the present application, when determining the target route, several alternative routes can be determined based on the departure place and the destination. The alternative routes here can include the fastest route, the shortest route, the route to avoid congestion, etc., and the present application does not limit their types and specific numbers. After obtaining the alternative routes, the alternative routes can be displayed to the user. At this time, the user can select the alternative routes to determine the target route. Of course, similarly, in an embodiment of the present application, if the user has not selected an alternative route for a long time, a certain alternative route can also be defaulted as the target route, such as the fastest route or the shortest route, and the present application does not limit this.

[0082] In the embodiment of the present application, after determining the target route, the estimated driving time can be determined according to the target route. Specifically, in the embodiment of the present application, the estimated driving time can be obtained by using historical traffic data and the average driving time of similar routes, and dynamically adjusting the estimated time in combination with the current traffic conditions.

[0083] In an embodiment of the present application, the height difference between the departure point and the destination can be calculated, and the proportion information of various road conditions on the target route can be obtained. Then, the spontaneous heat generated by driving can be determined based on the height difference, the proportion information and the estimated driving time. It can be understood that the factors affecting the spontaneous heat generated by driving mainly include: energy consumption caused by altitude changes, energy consumption under different road conditions, and energy consumption caused by driving time. Therefore, in an embodiment of the present application, based on relevant information, the spontaneous heat generated by driving that may be generated by new energy vehicles in this travel plan can be determined.

[0084] Next, the ambient temperature and battery cell temperature of the new energy vehicle can be detected, so as to determine the target heating temperature based on the ambient temperature, battery cell temperature, spontaneous heat generated during driving and driving mode, and then use the relevant heating components in the new energy vehicle to heat its battery, thereby making the new energy vehicle have a better driving experience.

[0085] It is understandable that a method for controlling battery heating of a new energy vehicle is provided in the embodiment of the present application, which obtains the user's travel plan information and determines the driving mode selected by the user; wherein the travel plan information includes information of the departure place and the destination; determines the target route according to the departure place and the destination, and determines the estimated driving time according to the target route; calculates the height difference between the departure place and the destination, obtains the proportion information of various road conditions on the target route, and determines the driving self-heat according to the height difference, the proportion information and the estimated driving time; detects the ambient temperature and battery cell temperature of the new energy vehicle, and determines the target heating temperature according to the ambient temperature, the battery cell temperature, the driving self-heat and the driving mode; heats the battery of the new energy vehicle according to the target heating temperature. This method can determine the appropriate heating temperature according to the environment of the new energy vehicle and the user's travel plan, realizes the heating of the battery of the new energy vehicle, and can take into account the vehicle's endurance and driving performance, and is more practical.

[0086] Specifically, in some embodiments, obtaining the user's travel plan information includes:

[0087] Obtaining travel plan information input by the user on the terminal device;

[0088] Alternatively, voice information of the user is received, the voice information is recognized, and the travel plan information of the user is obtained.

[0089] In the embodiments of the present application, when obtaining the user's travel plan information, in some embodiments, the user can directly input it on the relevant terminal device, and the travel plan information can be obtained based on the user's input; in other embodiments, the user's voice information can also be received and the voice information can be recognized to obtain the user's travel plan information. In the embodiments of the present application, there is no limitation on the voice recognition algorithm used here, and it can be implemented by referring to the relevant technology in the field.

[0090] Specifically, in some embodiments, obtaining the proportion information of various types of road conditions on the target route includes:

[0091] Detecting a total length of the target route, a first length of an urban road condition on the target route, a second length of a high-speed road condition on the target route, and a third length of a low-speed road condition on the target route;

[0092] Determining first proportion data corresponding to the urban road condition according to a ratio of the first length to the total length;

[0093] Determining second proportion data corresponding to the highway condition according to a ratio of the second length to the total length;

[0094] According to the ratio of the third length to the total length, third proportion data corresponding to the low-speed road condition is determined.

[0095] In the embodiment of the present application, when determining the proportion information of various road conditions on the target route, the total length of the target route, the length of the urban road condition, the high-speed road condition and the low-speed road condition on the target route can be detected, and their lengths are recorded as the first length, the second length and the third length respectively. Then, the first proportion data corresponding to the urban road condition can be determined according to the ratio of the first length to the total length, the second proportion data corresponding to the urban road condition can be determined according to the ratio of the second length to the total length, and the third proportion data corresponding to the urban road condition can be determined according to the ratio of the third length to the total length.

[0096] Specifically, in some embodiments, heating the battery of the new energy vehicle according to the target heating temperature includes:

[0097] If the ambient temperature is less than or equal to a preset temperature threshold, the battery of the new energy vehicle is heated according to the target heating temperature.

[0098] It is understandable that the new energy vehicle battery heating control method in the embodiment of the present application can heat the battery of the new energy vehicle when the ambient temperature is low, thereby improving the performance of the battery. Relatively speaking, when the ambient temperature is high, it is not necessary to execute the heating control logic. Therefore, in the embodiment of the present application, a preset temperature threshold can be set in advance. If the ambient temperature is low and is less than or equal to the preset temperature threshold, the battery of the new energy vehicle is heated according to the target heating temperature; conversely, if the ambient temperature is high and is greater than the preset temperature threshold, the battery of the new energy vehicle is not heated.

[0099] In the embodiment of the present application, the size of the preset temperature threshold can be flexibly set according to actual needs, and the present application does not impose any restrictions on this.
