[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0027] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0028] Figure 1 This is a flowchart illustrating a vehicle control method according to an exemplary embodiment, such as... Figure 1 As shown, the vehicle control method includes the following steps: In step S110, the target starting temperature of the vehicle's power battery is determined. The target starting temperature represents the optimal operating temperature of the power battery at the scheduled travel time.

[0029] In step S120, the heated temperature of the power battery at multiple candidate heating times is determined. The multiple candidate heating times are determined by traversing a preset time period.

[0030] In step S130, the heating start time is determined from multiple candidate heating times based on the target starting temperature and the already heated temperature, and the power battery is controlled to start heating according to the heating start time.

[0031] In the exemplary embodiments of this disclosure, all possible heating activation times before vehicle travel are determined by traversing a preset time period, and the corresponding heated temperature is determined, enabling positive simulation of the battery temperature at each candidate heating time. Furthermore, by determining the heating activation time from multiple candidate heating times based on the target initial temperature and the heated temperature, heating is performed. This not only ensures that the battery temperature meets the standard during travel but also accurately optimizes the determination of the best heating activation time, avoiding overheating or underheating of the power battery, reducing energy consumption issues caused by heating the power battery, and optimizing the user's driving experience.

[0032] The following is a detailed explanation of each step in the vehicle control method.

[0033] In step S110, the target starting temperature of the vehicle's power battery is determined. The target starting temperature represents the optimal operating temperature of the power battery at the scheduled travel time.

[0034] In an exemplary embodiment of this disclosure, in order to determine the target starting temperature of the power battery, the power battery's charge data can be obtained first, that is, the current SOC (State of Charge) data of the power battery, which can be represented as follows: .

[0035] Since a mapping table between SOC state data and heating start temperature has been calibrated offline, different SOC state data correspond to different target start temperatures in this mapping table. Therefore, after obtaining the current SOC state data of the power battery, it can be used in this mapping table according to... Target starting temperature The target starting temperature It is the optimal starting temperature when making a reservation, that is, the target temperature for reserving heating.

[0036] The target starting temperature is determined by the current SOC data of the power battery. Compared with the fixed target starting temperature scheme, the current target starting temperature can be determined adaptively by the SOC data. This ensures sufficient discharge performance when the power battery is low in charge and avoids unnecessary high-temperature heating when the power battery is high in charge. This improves the low-temperature availability of the power battery under different charge states and achieves more refined temperature control.

[0037] In step S120, the heated temperature of the power battery at multiple candidate heating times is determined. The multiple candidate heating times are determined by traversing a preset time period.

[0038] In an exemplary embodiment of this disclosure, the heated temperature of the power battery at multiple candidate heating moments can be further determined.

[0039] In an optional embodiment, determining the heated temperature of the power battery at multiple candidate heating moments includes: Acquire the state data of the power battery and the ambient temperature at multiple candidate heating moments, and determine the unheated temperature at multiple candidate heating moments based on the state data and ambient temperature; The preheated temperature of the power battery at multiple candidate heating moments is determined based on the unheated temperature.

[0040] The state data of the power battery can include the heat transfer coefficient between the battery and the external environment. Heat exchange area between battery and external environment Battery specific heat capacity and battery quality The heat transfer coefficient between the battery and the external environment. The heat exchange area between the battery and the external environment was obtained by fitting experimental data. It is determined by the battery pack structural parameters, including the battery's specific heat capacity. and battery quality It is determined by the battery specifications.

[0041] The preset time period is determined by the moment when the vehicle's high-voltage system is powered off and the moment the scheduled trip is made.

[0042] Within a preset time period from the start time to the end time, using time steps... Iterative calculations are performed to predict the unheated temperature at multiple candidate heating moments under dormant operation. Therefore, the ambient temperature at multiple candidate heating moments can also be obtained. , That is The ambient temperature at each time point is used to determine the unheated temperature for multiple candidate heating times based on the state data and ambient temperature.

[0043] Among them, time step It can be based on a 1-minute time step, starting from the moment the vehicle's high-voltage system is powered off. The calculation is iteratively performed point by point up to the scheduled travel time, thereby predicting the unheated temperature at any time during the entire dormancy period.

[0044] Specifically, determining the unheated temperature for multiple candidate heating moments based on state data and ambient temperature can be based on... It has been achieved. Among them, for The current heated temperature. for The current heated temperature. For time step, The heat transfer coefficient between the battery and the external environment. The heat exchange area between the battery and the external environment. for The ambient temperature at any given time for Battery temperature at any time, For the specific heat capacity of the battery, For battery quality.

[0045] In this exemplary embodiment, the unheated temperature at multiple candidate heating moments is determined based on state data and ambient temperature. This method can adapt to temperature prediction requirements under different ambient temperatures and battery states, has high prediction accuracy, and is applicable to a wide range of scenarios.

[0046] After determining the unheated temperature, the heated temperature of multiple candidate heating times can be further determined based on the unheated temperature.

[0047] In an optional embodiment, determining the heated temperature of the power battery at multiple candidate heating moments based on the unheated temperature includes: In response to the unheated temperature being lower than the target starting temperature, the heated temperature of the power battery at multiple candidate heating moments is determined based on state data, ambient temperature, and unheated temperature.

[0048] If the unheated temperature is lower than the target starting temperature within a preset time period, it can be determined that the power battery needs to be pre-heated during the dormancy period.

[0049] Specifically, starting from the moment the vehicle's high-voltage system shuts down, with a time step of 1 minute, the preset time period is iterated until the scheduled departure time is reached. During the iteration, it can be done according to... The method used is to determine the heated temperature of the power battery at multiple candidate heating moments. for The current heated temperature. for The current heated temperature. The power consumed for heating. For time step, The heat transfer coefficient between the battery and the external environment. The heat exchange area between the battery and the external environment. for The ambient temperature at any given time for Battery temperature at any time, For the specific heat capacity of the battery, For battery quality.

[0050] Therefore, the heated temperature of the power battery at multiple candidate heating moments can be determined based on the state data, ambient temperature, and unheated temperature. The multiple heated temperatures This refers to the battery temperature set at the scheduled travel time. .

[0051] In an optional embodiment, the power battery is controlled not to heat up in response to the unheated temperature being greater than or equal to the target starting temperature.

[0052] If the unheated temperature is never lower than the target starting temperature within the preset time period, that is, if the unheated temperature is always greater than or equal to the target starting temperature, it indicates that there is no need to pre-heat the power battery during the dormancy period.

[0053] In step S130, the heating start time is determined from multiple candidate heating times based on the target starting temperature and the already heated temperature, and the power battery is controlled to start heating according to the heating start time.

[0054] In an exemplary embodiment of this disclosure, after determining the target starting temperature and the heated temperature, the heating start time can be determined from multiple candidate heating times based on the target starting temperature and the heated temperature.

[0055] In an optional embodiment, determining the heating start time from multiple candidate heating times based on the target starting temperature and the already heated temperature includes: Among the heated temperatures, determine the heated temperature with the smallest temperature difference from the target starting temperature, and determine the candidate heating time corresponding to the heated temperature with the smallest temperature difference as the heating start time.

[0056] After obtaining the battery temperature data at the scheduled travel time... Then, the target initial temperature and the battery temperature set can be calculated. The temperature difference between each heated temperature in the battery is used to determine the candidate heating time corresponding to the heated temperature with the smallest temperature difference. In other words, the battery temperature set is selected. Neutral with target starting temperature The closest moment is taken as the heating start time.

[0057] In this exemplary embodiment, the moment when the heated temperature is closest to the target starting temperature is selected as the heating start time. This can reduce heating energy consumption while ensuring that the travel temperature meets the standard. At the same time, it avoids the cumulative error caused by ignoring the temperature changes during the dormancy period in the time-based calculation method, thus improving the accuracy of the heating start time.

[0058] Furthermore, the power battery is controlled to start heating based on the heating start time.

[0059] In an optional embodiment, controlling the power battery to start heating according to the heating start time includes: Save the moment the heating is turned on to the vehicle's persistent storage unit; In response to the vehicle's timing unit reaching the heating start time, the power battery is controlled to start heating.

[0060] To ensure that the data on when the heater is turned on after the vehicle goes into sleep mode is not lost, the data on when the heater is turned on can be written to NVM (Non-Volatile Memory).

[0061] During vehicle sleep mode, the MCU (Microcontroller Unit) clock chip maintains low power operation. Upon detecting the heating start time stored in the NVM, a hardware interrupt wakes up the BMS (Battery Management System) controller, initiating the heating execution process. This prevents the BMS from remaining in standby mode throughout the entire sleep cycle, significantly reducing system power consumption while ensuring the accuracy of heating timing. After the BMS is woken up, it controls the power battery to begin heating, specifically through a PTC (Positive Temperature Coefficient Heater).

[0062] In an optional embodiment, the real-time heating temperature of the power battery during the heating process is obtained; In response to a real-time heating temperature greater than or equal to a preset temperature threshold, the power battery is controlled to stop heating. The temperature threshold is determined based on the target starting temperature.

[0063] During the heating process of the power battery, the BMS can monitor the real-time heating temperature of the power battery. When this real-time heating temperature is greater than or equal to a preset temperature threshold, the BMS can control the power battery to stop heating, and the vehicle will re-enter a dormant state, awaiting the user's departure. The temperature threshold can be determined based on a target starting temperature; for example, the temperature threshold could be the target starting temperature. and preset temperature margin The sum of these, the temperature margin It can be set to 0.5℃ or 1℃, and this exemplary embodiment does not make any special limitation in this regard.

[0064] In the exemplary embodiments of this disclosure, all possible heating activation times before vehicle travel are determined by traversing a preset time period, and the corresponding heated temperature is determined, enabling positive simulation of the battery temperature at each candidate heating time. Furthermore, by determining the heating activation time from multiple candidate heating times based on the target initial temperature and the heated temperature, heating is performed. This not only ensures that the battery temperature meets the standard during travel but also accurately optimizes the determination of the best heating activation time, avoiding overheating or underheating of the power battery, reducing energy consumption issues caused by heating the power battery, and optimizing the user's driving experience.

[0065] Furthermore, in an exemplary embodiment of this disclosure, a vehicle control device is also provided.
