[0037] 113. Collect the fifth ambient temperature at the beginning of battery cooling, the third highest battery temperature, and the sixth ambient temperature at the end of cooling, the third highest battery temperature.

[0038] It can be understood that the ambient temperature and battery temperature at the moment before the vehicle sleeps, the ambient temperature and battery temperature at the first moment when the vehicle wakes up, the ambient temperature and battery temperature at the beginning and end of battery heating, the ambient temperature and battery temperature at the beginning and end of battery cooling, the collected data are sent to the cloud, the collected data are analyzed and matched by the cloud, and the scene number is calculated, the temperature change parameter under each scene is calculated, and the vehicle end heat preservation wake-up time calculation parameter is updated.

[0039] On the basis of the above embodiment, the battery heat preservation control method can be further embodied as: the heat preservation mode is obtained and sent to the cloud, comprising:

[0040] 114. Receive the first battery heat preservation mode and the first heat preservation time set by the client for the first time for storage and send to the cloud.

[0041] 115. Receive the second battery heat preservation mode and the second heat preservation time set by the client for the second time, compare the first battery heat preservation mode and the second battery heat preservation mode, and compare the first heat preservation time and the second heat preservation time.

[0042] 116. If the first battery heat preservation mode and the second battery heat preservation mode are different, and / or the first heat preservation time and the second heat preservation time are different, store the second battery heat preservation mode and the second heat preservation time, send to the cloud in combination with the setting change identifier, and feedback the setting success information to the client.

[0043] Specifically, the vehicle end battery controller receives and stores the heat preservation mode sent by the user end, wherein the heat preservation mode includes user heat preservation time and mode signal, wherein the user end can be a vehicle end human-computer interaction interface, a client or an APP, etc.

[0044] Optionally, the vehicle end battery controller receives the battery heat preservation mode and the heat preservation time set by the user on the vehicle end human-computer interaction interface or the client, and the setting source can be an instrument, a central control interface, a mobile phone APP, etc. The battery heat preservation mode can be single heat preservation or cycle heat preservation, wherein the heat preservation time ranges from 00:00 to 23:59.

[0045] Optionally, when the user sets the first battery heat preservation mode and the first heat preservation time for the first time, the vehicle end battery controller writes the received first battery heat preservation mode and first heat preservation time into the memory and sends it to the cloud.

[0046] Optionally, when the user sets the second battery temperature maintenance mode and the second temperature maintenance time for the first time, the vehicle-side battery controller compares the received second battery temperature maintenance mode and the second temperature maintenance time with the first battery temperature maintenance mode and the first temperature maintenance time in the memory. If the signal values of the mode and the time are inconsistent, the newly set second battery temperature maintenance mode and the second temperature maintenance time are written into the memory, and a feedback is given to the vehicle-side human-computer interaction interface or the client-side that the setting is successful, and the second battery temperature maintenance mode and the second temperature maintenance time and the setting change identifier sent to the cloud are synchronously updated; if the signal values of the mode and the time are consistent, the battery temperature maintenance mode and the temperature maintenance time do not need to be updated.

[0047] 120. Receive the scene parameters, calculate the battery temperature maintenance wake-up time in combination with the temperature maintenance mode, and send to the cloud.

[0048] Optionally, when the vehicle-side battery controller identifies that the vehicle has completed charging and the AC charging gun remains in the connected state and the vehicle is not in sleep mode, if the user has not set the battery temperature maintenance mode, i.e., the battery temperature maintenance mode sent by the client has not been received, the battery temperature maintenance wake-up time calculation function is not started; if the user has set the battery temperature maintenance mode, i.e., the battery temperature maintenance mode sent by the client has been received, the battery temperature maintenance wake-up time is calculated according to the relationship between the user-set temperature maintenance time and the current time.

[0049] On the basis of the above-mentioned embodiments, the battery temperature maintenance control method can also be embodied as: the receiving of the scene parameters and the calculating of the battery temperature maintenance wake-up time in combination with the temperature maintenance mode include:

[0050] 121. Receive the scene parameters from the cloud.

[0051] 122. When it is identified that the vehicle has completed charging and the AC charging gun remains in the connected state and the vehicle is not in sleep mode, if the battery temperature maintenance mode from the user end has not been received, the battery temperature maintenance wake-up time calculation function is not started.

[0052] 123. If the battery temperature maintenance mode from the user end is received, the difference between the user-set temperature maintenance time and the current time is compared.

[0053] 124. If the difference between the user-set temperature maintenance time and the current time is less than or equal to a first temperature maintenance wake-up interval, the battery temperature maintenance wake-up time calculation is not performed; wherein the first temperature maintenance wake-up interval is calculated through the scene parameters.

[0054] 125. If the difference between the user-set temperature maintenance time and the current time is greater than the first temperature maintenance wake-up interval, the battery temperature maintenance wake-up time calculation is performed.

[0055] 126. The battery temperature maintenance wake-up time is calculated according to the scene parameters.

[0056] Optionally, when the vehicle end battery controller identifies that the vehicle has completed charging and the AC charging gun remains connected and the vehicle is not in sleep, if the user has not set the battery warm-up mode, i.e., the battery warm-up mode sent by the client is not received, the battery warm-up wake-up time calculation function is not started; if the user has set the battery warm-up mode, i.e., the battery warm-up mode sent by the client is received, the relationship between the user-set warm-up time and the current time is compared, and the battery warm-up wake-up time is calculated.

[0057] For example, the difference between the user-set warm-up time and the current time is calculated: Δt kt = t kt0 - t now .

[0058] Wherein, t kt0 is the user-set warm-up time, and t now is the current time.

[0059] If 0 < Δt kt ≤ Δt1, the warm-up wake-up time calculation is not performed, and the battery warm-up control function enable flag is set to 0, wherein Δt1 is calculated by the current battery heating scene or cooling scene parameters.

[0060] If the collected minimum battery temperature is lower than the heating start temperature, the battery heating scene parameters are used to calculate Δt1 = Δt H .

[0061] Wherein, K H is the battery temperature rise rate of the battery heating scene, T H0 is the heating start temperature, and T Min is the minimum battery temperature.

[0062] If the maximum battery temperature is higher than the cooling start temperature, the battery cooling scene parameters are used to calculate Δt1 = Δt C .

[0063] Wherein, K C is the battery temperature rise rate of the battery cooling scene, T C0 is the cooling start temperature, and T Max is the maximum battery temperature.

[0064] If Δt1 < Δt kt ≤ 2Δt1, the warm-up wake-up time calculation is not performed, the battery warm-up control function enable flag is set to 1, and the battery warm-up execution control function is directly triggered.

[0065] If Δt kt>2Δt1, the battery heat preservation control function enable identifier is set to 0, the heat preservation wake-up time t is calculated through the vehicle hibernation scene parameter and the battery heating scene or cooling scene parameter kt .

[0066] Specifically, by comparing the current environment temperature, the battery minimum temperature, the battery maximum temperature and the label value of the vehicle hibernation scene, if the temperature deviation is ±2℃, it is considered that the scene matches, and the parameter group of the scene is adopted.

[0067] The battery heat preservation wake-up time is calculated. Max And the battery minimum temperature T' Min :

[0068] Wherein, The battery minimum temperature change rate of the battery hibernation scene is ΔT The battery maximum temperature change rate of the battery hibernation scene is ΔT

[0069] If the battery maximum temperature is higher than the cooling start temperature, the heat preservation wake-up time is t kt =t kt0 -Δt C .

[0070] If the battery minimum temperature is lower than the heating start temperature, the heat preservation wake-up time is t kt =t kt0 -Δt H .

[0071] If the difference between the predicted battery maximum temperature and the battery minimum temperature is greater than the preset temperature difference value, the battery heat preservation control function enable identifier is set to 0, and the heat preservation wake-up time is set to an invalid value.

[0072] The battery heat preservation wake-up time is sent to the cloud, the vehicle end memory is synchronously stored, the cloud feedback signal “reception success” is received, and the vehicle hibernation process is started.

[0073] It can be understood that the specific value of the preset temperature difference value can be set according to requirements, and the embodiments of the application do not limit this.

[0074] 130, receiving the heat preservation wake-up signal of the cloud to execute the battery heat preservation control, and feeding back the wake-up result to the cloud.

[0075] Specifically, the vehicle end receives the heat preservation wake-up signal of the cloud, the vehicle end is woken up, the wake-up mode is received, and the vehicle end storage information is checked, such as checking through, the vehicle end performs heat preservation control, such as this time wake-up not meeting the heat preservation condition, the cloud is counted not meeting the reason, and the cloud calculation heat preservation wake-up time parameter is synchronously updated, such as checking not through, the cloud checking result is fed back.

[0076] On the basis of the above-mentioned embodiments, the battery heat preservation control method can also be embodied as: receiving the heat preservation wake-up signal from the cloud end to execute the battery heat preservation control and feeding back the wake-up result to the cloud end, comprising:

[0077] 131. Receiving the heat preservation wake-up signal and the wake-up mode sent by the cloud end based on the heat preservation mode and the battery heat preservation wake-up time, and checking with the storage information of the vehicle end.

[0078] 132. If the checking is passed, the vehicle end executes the battery heat preservation control and feeds back the control result to the cloud end.

[0079] Specifically, when it is identified that the vehicle has completed charging and the AC charging gun remains in the connected state and the vehicle is not in sleep, the battery heat preservation control function identifier is valid; if the lowest battery temperature is lower than the heating start temperature, the heating control is started; if the highest battery temperature is higher than the cooling start temperature, the cooling control is started; when the heating control or the cooling control is normally started and reaches the target temperature, the heating control or the cooling control is stopped, and the battery heat preservation mode is judged; if the heat preservation mode is single heat preservation, the stored heat preservation mode and heat preservation wake-up time are cleared, and the initial storage state is restored; if the heat preservation mode is cyclic heat preservation, the stored heat preservation mode is kept, and the heat preservation wake-up time is recalculated.

[0080] 133. If the checking is not passed, the vehicle end does not start the battery heat preservation control function, feeds back the heat preservation start failure reason to the cloud end to instruct the cloud end to update the scene parameters.

[0081] Optionally, the vehicle end battery controller receives the wake-up mode sent by the cloud end as heat preservation wake-up, compares the current time with the battery heat preservation wake-up time in the storage, and if the difference between the two is less than or equal to the first set wake-up time threshold, the battery heat preservation control function enable identifier is set to 1, wherein the specific value of the set wake-up time threshold can be set according to specific requirements.

[0082] Optionally, when the vehicle end battery controller identifies that the vehicle has completed charging and the AC charging gun remains in the connected state and the vehicle is not in sleep, the battery heat preservation control function enable identifier is 1, if the lowest battery temperature is lower than the heating start temperature or the highest battery temperature is higher than the cooling start temperature, the heating control or the cooling control is started, otherwise, the heating control or the cooling control is not started.

[0083] If the heating control or the cooling control is normally started, the heating control or the cooling control is stopped when the heating target temperature or the cooling target temperature is reached, and the battery heat preservation mode is judged.

[0084] If the heat preservation mode is single heat preservation, the stored battery heat preservation mode and battery heat preservation wake-up time are cleared, and the initial storage state is restored; if the heat preservation mode is cycle heat preservation, the stored battery heat preservation mode is maintained, and the heat preservation wake-up time is recalculated.

[0085] Optionally, if the vehicle-side battery controller wakes up on time for heat preservation, but does not meet the verification condition, the heat preservation control function is not started, and the cloud is fed back the heat preservation start failure reason, and the cloud updates the scene parameters. If the vehicle-side battery controller wakes up on time for heat preservation, but does not meet the temperature condition, the heat preservation control function is not started, and the cloud is fed back the heat preservation start failure reason, and the cloud updates the scene parameters.

[0086] In the above, the vehicle information, temperature data and heat preservation mode are obtained and sent to the cloud to instruct the cloud to match the scene according to the vehicle information and the temperature data, and calculate the scene parameters; wherein the temperature data includes the ambient temperature and the battery temperature; receive the scene parameters, calculate the battery heat preservation wake-up time in combination with the heat preservation mode and send it to the cloud; receive the heat preservation wake-up signal from the cloud to execute the battery heat preservation control, and feed back the wake-up result to the cloud; the execution and parameters of the vehicle battery heat preservation can be flexibly adjusted according to the vehicle information, the temperature data and the use scene of the vehicle, and the temperature of the battery can be intelligently and accurately controlled.

[0128] Exemplarily, the vehicle hibernation scenarios are tagged with the first ambient temperature, the first battery minimum temperature, the first battery maximum temperature, the second ambient temperature, the second battery minimum temperature, and the second battery maximum temperature, the scenario numbers are S1-Sn, and each scenario includes the parameter group of the battery minimum temperature change rate and the battery maximum temperature change rate.

[0130] Exemplarily, the battery cooling scenarios are tagged with the fifth ambient temperature, the third battery maximum temperature, the sixth ambient temperature, and the third battery maximum temperature, the scenario numbers are SC1-SC2, and each scenario includes the parameter of the battery temperature drop rate.

[0131] Optionally, the preset time period is used for the cloud end to send the scenario tag and the scenario parameter group to the vehicle end battery controller, so as to synchronize the storage of the vehicle end and the cloud end.

[0132] 230. receiving the battery temperature maintenance wake-up time of the vehicle end, and calibrating the current battery temperature maintenance wake-up time of the vehicle end in real time.

[0133] Specifically, the vehicle end battery controller uploads the battery temperature maintenance wake-up time, the cloud end identifies and judges the scenario tag of the vehicle end, acquires the ambient temperature information in the vicinity in real time through the scenario tag of the vehicle end, adjusts the scenario number of the cloud end according to the ambient temperature change, matches the temperature change parameter through the corresponding scenario number, calibrates the temperature maintenance wake-up time of the cloud end, compares the temperature maintenance wake-up time uploaded by the vehicle end with the calibrated temperature maintenance wake-up time of the cloud end, and controls the vehicle end battery controller to wake up according to the temperature maintenance wake-up time uploaded by the vehicle end if the deviation is within the preset range, or controls the vehicle end battery controller to wake up according to the calibrated temperature maintenance wake-up time of the cloud end if the deviation is outside the preset range.

[0134] On the basis of the above embodiment, the battery temperature maintenance control method can also be embodied as: the receiving the battery temperature maintenance wake-up time of the vehicle end, and calibrating the current battery temperature maintenance wake-up time of the vehicle end in real time, includes:

[0135] 231. receiving the battery temperature maintenance wake-up time of the vehicle end, and acquiring the real-time ambient temperature information of the vehicle end.

[0136] 232. judging the scenario tag through the real-time ambient temperature information to acquire the scenario parameter.

[0137] 233. matching the temperature change parameter according to the scenario parameter, and calibrating the temperature maintenance wake-up time of the cloud end.

[0138] 234、compare the difference between the battery warm-up wake-up time at the vehicle end and the calibrated warm-up wake-up time at the cloud end, if the difference is within the preset calibration value, the battery warm-up wake-up time at the vehicle end is adopted, if the difference exceeds the preset calibration value, the calibrated warm-up wake-up time at the cloud end is taken as the battery warm-up wake-up time.

[0139] For example, the cloud end matches the scene in real time, the cloud end uploads data through the battery controller at the vehicle end, identifies the vehicle hibernation time, obtains the ambient temperature data near the location information at the vehicle hibernation time, compares the current ambient temperature, the minimum battery temperature and the maximum battery temperature with the label value of the vehicle hibernation scene, such as temperature deviation ±2℃, considers that the scene is matched, adopts the parameter group of the scene, and calculates the warm-up wake-up time of the cloud end in real time according to the identified scene parameters. It can be understood that the calculation method of the warm-up wake-up time of the cloud end is the same as that of the battery warm-up wake-up time at the vehicle end.

[0140] For example, the cloud end calibrates the battery warm-up wake-up time, first calculates the difference between the warm-up wake-up time of the cloud end and the battery warm-up wake-up time at the vehicle end: Δt ktC =t' kt -t kt .

[0141] Wherein, t′ kt is the warm-up wake-up time of the cloud end, t kt is the battery warm-up wake-up time at the vehicle end.

[0142] If the difference between the two is less than the first set wake-up time threshold or greater than the second set wake-up time threshold, the battery warm-up wake-up time is not adjusted; if the difference between the two is between the first set wake-up time threshold and the second set wake-up time threshold, the calibrated warm-up wake-up time of the cloud end is taken as the battery warm-up wake-up time, and the cloud end calibrated battery warm-up wake-up time is used to control the vehicle end battery controller to wake up and start the battery warm-up control function.

[0143] 240, based on the warm-up mode and the battery warm-up wake-up time, send a warm-up wake-up signal to the vehicle end to control the vehicle end to execute battery warm-up, and receive the feedback check result of the vehicle end.

[0144] Specifically, the cloud end identifies that the battery warm-up wake-up time has arrived, identifies that the wake-up mode is set to warm-up wake-up, sends a warm-up wake-up signal to the vehicle end, wakes up the vehicle end battery controller to start the warm-up control function, and receives the feedback check result of the vehicle end.

[0145] In some embodiments, the vehicle-side battery controller receives the wake-up mode sent by the cloud, and the wake-up mode is battery-warming wake-up. The current time is compared with the battery-warming wake-up time in the memory. If the difference between the two is less than or equal to a first set wake-up time threshold, the battery-warming control function enable identifier is set to 1. The specific value of the set wake-up time threshold can be set according to specific requirements.

[0146] Optionally, when the vehicle-side battery controller identifies that the vehicle has completed charging and the AC charging gun remains connected and the vehicle is not in sleep mode, the battery-warming control function enable identifier is 1. If the minimum battery temperature is lower than the heating start temperature or the maximum battery temperature is higher than the cooling start temperature, the heating control or the cooling control is started. Otherwise, the heating control or the cooling control is not started.

[0147] If the heating control or the cooling control is normally started, the heating control or the cooling control is stopped when the heating target temperature or the cooling target temperature is reached. The battery-warming mode is determined.

[0148] If the warming mode is single warming, the stored battery-warming mode and battery-warming wake-up time are cleared, and the initial storage state is restored. If the warming mode is cyclic warming, the stored battery-warming mode is maintained, and the warming wake-up time is recalculated.

[0149] Optionally, if the vehicle-side battery controller wakes up on time, but does not meet the verification conditions, the warming control function is not started, and the cloud is fed back the warming start failure reason. The cloud updates the scene parameters.

[0150] In the above, the embodiments of the application receive vehicle information, temperature data and warming mode from the vehicle side. The temperature data includes ambient temperature and battery temperature. Scene matching is performed according to the vehicle information and the temperature data, and scene parameters are calculated. The battery-warming wake-up time from the vehicle side is received, and the current battery-warming wake-up time of the vehicle side is calibrated in real time. Based on the warming mode and the battery-warming wake-up time, a warming wake-up signal is sent to the vehicle side to control the vehicle side to perform battery warming. Feedback verification results from the vehicle side are received. The execution and parameters of the vehicle battery warming can be flexibly adjusted according to the vehicle information, the temperature data and the use scene of the vehicle. The temperature of the battery is intelligently and accurately controlled.

[0151] In the above, the cloud side of the embodiments of the application identifies the same type of battery temperature change scene with the same type of battery temperature change with the environment temperature change through vehicle upload data. The temperature change rate in each scene is calculated. The vehicle-side warming wake-up time calculation parameters are updated. The problem that the vehicle-side battery controller cannot identify different user habits and the error is large due to the single parameter or formula calculation of the warming wake-up time is solved.

[0152] The vehicle-end battery controller calculates and uploads the temperature-maintaining wake-up time to the cloud, and the cloud calibrates the wake-up time according to the change of the ambient temperature during the vehicle hibernation, to solve the blind spot of the judgment on the temperature change rate during the vehicle hibernation. The vehicle-end performs the temperature-maintaining control, and if the current wake-up does not meet the temperature-maintaining condition, the cloud counts the reasons for not meeting the condition, and synchronously updates the parameters of the temperature-maintaining wake-up time calculated by the cloud, to continuously optimize the battery temperature-maintaining control function, so that the wake-up time calculation is more accurate.
