[0057] With the advancement of electronic technology, new energy vehicles (NEVs) powered primarily by batteries are gaining widespread adoption. These vehicles face numerous challenges operating in low-temperature environments, particularly as the performance of their power batteries can be significantly impacted. To ensure proper operation and performance in low-temperature conditions, batteries are typically heated before or during operation.

[0058] In related technologies, battery heating is performed by heating the cells to a pre-set temperature threshold before stopping. This process consumes the battery's own energy. In actual applications, this strategy often fails to meet user needs. For example, if the heating temperature threshold is set too high, the vehicle's range will be affected; or if the heating temperature threshold is set too low, battery performance will be limited, preventing a good driving experience and thus posing a low practicality issue.

This method can determine the appropriate heating temperature according to the environment in which the new energy vehicle is located and in combination with the user's travel plan, thereby heating the battery of the new energy vehicle, taking into account both the vehicle's endurance and driving performance, and is more practical.

[0060] Next, we first introduce the implementation environment of the new energy vehicle battery heating control method provided in the embodiment of this application. Figure 1 , Figure 1 A schematic diagram of an implementation environment for a method for controlling battery heating in a new energy vehicle is provided. The hardware and software components of this implementation environment primarily include a terminal device 110 and a server 120, which are in communication with each other. The method can be implemented on the terminal device 110 or through interaction between the terminal device 110 and the server 120.

[0061] Specifically, in the embodiments of the present application, the terminal device 110 can include, but is not limited to, any one or more of a smart watch, a smart phone, a computer, a personal digital assistant (PDA), a smart voice interaction device, a smart home appliance, or a vehicle-mounted terminal. The server 120 can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and basic cloud computing services such as big data and artificial intelligence platforms. The terminal device 110 and the server 120 can establish a communication connection through a wireless network or a wired network, which uses standard communication technology and / or protocols. The network can be set as the Internet, or any other network, such as any combination of 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 can be understood that Figure 1 The implementation environment in Figure 1 is only one optional application scenario of the new energy vehicle battery heating control method provided in the embodiments of the present application, and the actual application is not fixed to Figure 1 The implementation environment shown in The new energy vehicle battery heating control method provided in the embodiments of the present application will be described in detail.

[0063] Figure 2 Please refer to Figure 2 , Figure 2 The new energy vehicle battery heating control method provided in the present application includes but is not limited to:

[0064] Step 210, obtaining the travel plan information of the user and determining the driving mode selected by the user; wherein the travel plan information includes the information of the departure place and the destination;

[0065] Step 220, determining the target route according to the departure place and the destination, and determining the estimated driving duration according to the target route;

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

[0067] Step 240: Detecting the ambient temperature and battery core temperature of the new energy vehicle, and determining a target heating temperature based on the ambient temperature, the battery core temperature, the self-generated heat during driving, and the driving mode;

[0068] Step 250: Heat 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 the appropriate heating temperature based on 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 embodiments 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 and destination. In addition, in the embodiments of the present application, the user's selected driving mode can also be obtained. For example, in some embodiments, determining the user's selected driving mode 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 of the preset optional mode.

[0073] In the embodiments of the present application, when determining the driving mode selected by the user, the user can be shown preset selectable modes. The types of the preset selectable modes can include a power mode, a regular mode, and an endurance mode. The power mode is a mode for high performance output of the new energy vehicle. In the power mode, the throttle response is more sensitive, and the driver can feel faster acceleration and more direct power transmission. Relatively, the energy consumption in the power mode is higher due to high power output, and the endurance mileage is relatively shorter. In the regular mode, the performance and energy consumption of the vehicle reach a balanced state, which ensures sufficient power output and takes into account energy efficiency. In this mode, the throttle response is moderate, the driving experience is more stable and comfortable, and the mode is suitable for common scenarios such as urban commuting and daily driving, and is the default mode for most users. Compared with the power mode, the energy consumption in the regular mode is lower, but slightly higher than that in the endurance mode. In the endurance mode, the control system of the vehicle optimizes various parameters to maximize the endurance mileage, and the throttle response becomes slower, and the acceleration performance is relatively weak.

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

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

[0076] In the embodiments of the present application, after obtaining the travel plan information of the user, the target route can be determined according to the departure location and the destination. Specifically, in the embodiments of the present application, the departure location and the destination can be address resolved and path planned using a third-party map service (such as Google Maps API, Gaode Map API, etc.), so as to determine the target route. In some cases, when determining the target route, a plurality of alternative results can be provided for the user to select.

[0077] For example, in some embodiments, the target route is determined according to the departure location and the destination, including:

[0078] determining a plurality of alternative routes according to the departure location 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 point and the destination. The alternative routes here can include the fastest route, the shortest route, the route to avoid congestion, etc., and this 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 does not select 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 this application does not limit this.

[0082] In an embodiment of the present application, after determining a target route, an estimated driving duration can be determined based on the target route. Specifically, in an embodiment of the present application, historical traffic data and average driving times of similar routes can be used for estimation, and the estimated time can be dynamically adjusted in combination with current traffic conditions to obtain an estimated driving duration.

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

[0084] Next, the ambient temperature and battery cell temperature of the new energy vehicle can be detected, and the target heating temperature can be determined based on the ambient temperature, battery cell temperature, driving self-heating and driving mode, and then the relevant heating components in the new energy vehicle can be used to heat its battery, so that the new energy vehicle has a better driving experience.

[0085] It is understandable that a method for controlling battery heating of a new energy vehicle is provided in an 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 based on the departure place and the destination, and determines the estimated driving time based on the target route; calculates the altitude 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-heating according to the altitude 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-heating and the driving mode; and 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 in which the new energy vehicle is located and in combination with the user's travel plan, thereby heating the battery of the new energy vehicle, taking into account both 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] Obtain travel plan information entered by the user on the terminal device;

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

[0089] In the embodiments of the present application, when obtaining a user's travel plan information, in some embodiments, the user can directly input the information on a 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 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 relevant technologies in the field.

[0090] Specifically, in some embodiments, obtaining information on the proportion of various 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 an embodiment of the present application, when determining the proportion of various road conditions on a target route, the total length of the target route and the lengths of the urban road conditions, highway road conditions, and low-speed road conditions on the target route can be detected, and their lengths can be recorded as a first length, a second length, and a third length, respectively. Then, based on the ratio of the first length to the total length, a first proportion data corresponding to the urban road conditions can be determined; based on the ratio of the second length to the total length, a second proportion data corresponding to the urban road conditions can be determined; and based on the ratio of the third length to the total length, a third proportion data corresponding to the urban road conditions can be determined.

[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 pre-set. If the ambient temperature is low and 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 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.

[0100] The following describes a new energy vehicle battery heating control device proposed according to an embodiment of the present application with reference to the accompanying drawings.
