Referring to fig. 1, an embodiment of the present invention provides a method for controlling automatic heating of a battery pack,
here, in the embodiment of the present invention, a remote controller may perform the following operations, where the remote controller may transmit data with a preset cloud via a wireless network, and a user may send a control instruction via a mobile phone APP, so that the remote controller receives the control instruction of the user. Here, the remote control controller can work correspondingly when the whole vehicle is powered off.
The method comprises the following steps:
the working state may include whether the entire vehicle is in a power-on state, for example, by interacting with the entire vehicle controller, if no response is obtained, it may be inferred that the entire vehicle is currently in a power-off state.
If the whole vehicle is in a power-on state, the fact that the user is currently using the vehicle can be indicated, operation can not be conducted, the battery pack can be heated according to a user instruction, the instruction can be sent through vehicle interaction, and the instruction can also be sent through APP.
here, the user can set a vehicle use time, for example, 7 am every day, by which the heating process of the battery pack is facilitated in advance. The user can set or modify the vehicle service time through the central control unit on the vehicle, and can also set the vehicle service time through the APP.
103, if the time from the current moment to the use time of the vehicle is less than a first preset value, acquiring real-time state information of the vehicle;
here, the first preset value may be calibrated according to experiments or the like.
Optionally, the real-time status information of the vehicle includes: vehicle door status information and battery pack status information; wherein the battery pack status information includes: the current real-time temperature of the battery pack and the current remaining capacity of the battery pack.
And 104, heating the battery pack if the real-time state information of the vehicle indicates that the heating condition of the battery pack is met currently.
Here, the heating condition of the battery pack may be: the vehicle door state information indicates that all current vehicle doors are in an unopened state, the real-time temperature is smaller than a second preset value, and the residual electric quantity is larger than a third preset value.
Here, the vehicle door may include four doors and two covers, and the vehicle is in an unopened state, and it may be inferred that the user is not currently using the vehicle. The second preset value can be set according to the corresponding relation between the battery performance and the temperature, and when the battery temperature is lower than the second preset value, the battery pack is indicated to be in a better temperature environment if the current temperature service performance is lower and the temperature has a larger influence on the battery pack, and heating operation is needed, so that the battery pack is in a better temperature environment, and the performance of the battery is improved. Furthermore, the embodiment of the invention also judges the residual electric quantity, if the residual electric quantity of the current battery is lower, the heating operation further consumes the electric quantity of the battery, and the heating operation is not suitable.
Optionally, after the battery pack is heated, the method further includes: and sending prompt information that the battery pack is in a heating state at present to a preset cloud. Here, by prompting the user of the heating state of the battery pack, it is convenient for the user to know the current state of the vehicle.
Further, if the user does not need to use the vehicle when setting for time, then the user can send the control command that stops to heat the battery package through cell-phone APP, and when the remote control controller received the control command that stops to heat the battery package, the stop heats the battery package.
Furthermore, the user can also set a second vehicle use time through the APP, the second vehicle use time can be a temporary use time, when the remote control controller receives the second vehicle use time, the heating of the battery pack is stopped, the timing operation is carried out, and the heating operation is carried out on the battery pack before the second vehicle use time.
Optionally, after the battery pack is heated, the method further includes:
acquiring temperature information of the battery pack;
and when the temperature information shows that the temperature of the battery pack is greater than a second preset value, stopping heating the battery pack.
Here, the second preset value may be set according to a correspondence relationship between the performance of the battery pack and the temperature at which the performance of the battery pack is superior. It can be understood that, in a low-temperature environment, the battery pack may be cooled down again, and the first preset value may be optimized to solve the temperature, so that a difference between a time for heating the battery pack to the second preset value and the first preset value is less than a threshold value, thereby completing the heating operation when the user uses the vehicle. Of course, it is also possible to perform step 101 again after the heating of the battery pack is completed, so that the heating operation is performed again when the temperature of the battery pack does not satisfy the condition.
Optionally, when the time from the current moment to the use time of the vehicle is less than a first preset value, the method further includes: awakening a vehicle controller and a battery management controller of the vehicle;
here, since the vehicle needs to be powered on for acquiring the state information of the battery and heating the battery, the remote control controller may wake up the vehicle controller of the vehicle and wake up the battery management controller through the vehicle controller.
After stopping heating the battery pack, the method further comprises: and controlling the whole vehicle to be powered off through the whole vehicle controller.
Referring to fig. 3 and 4, embodiments of the present invention will be further described.
When the automobile is used for the first time, a driver needs to set the service time of the automobile through the central control controller (for example, 7 points per day), the service time can be stored in the whole automobile controller after the setting is finished, and if the service time of the automobile needs to be changed, the service time can be changed through the central control controller after the automobile is powered on.
Firstly, judging whether the vehicle is powered on at present, if the vehicle is powered on, considering that a user uses the vehicle in advance, and not entering the system at the moment.
If the vehicle is not powered on, the user is considered not to use the vehicle at the moment, and the remote control controller judges that the current time is compared with the set vehicle using time.
If the time difference is greater than or equal to T0 (standard amount), the user is considered not to use the vehicle at the moment, and the remote control controller continues to count time and wait.
If the time difference is smaller than T0 (standard quantity), the user is considered to be about to use the vehicle, the battery pack can be heated in the test, the remote control controller wakes up the vehicle controller through a hard wire, and the vehicle controller wakes up the battery management controller through the hard wire after being woken up. And then the vehicle control unit judges the battery temperature.
If the battery temperature is greater than or equal to T1 (standard amount), the current battery temperature is considered to be higher, the vehicle is used for not influencing the battery pack at the moment, and the whole vehicle is powered off.
If the battery temperature is lower than T1T2 (standard amount), the current battery temperature is considered to be lower, at the moment, the vehicle has great influence on the battery pack, and the SOC of the current battery pack is judged again.
If the current SOC is smaller than A (standard quantity), the current battery pack electric quantity is considered to be low, and the battery pack is not heated as far as possible because the user needs to use the vehicle.
If the current SOC is larger than or equal to A (standard quantity), the electric quantity of the current battery pack is considered to be high, the battery pack can be heated, and then the vehicle door state and the current temperature of the battery are judged.
If the vehicle door state is completely closed and the battery temperature is less than T2 (calibration amount), the battery management controller opens the battery pack for heating through a hard wire closed relay, and the remote control controller transmits the heating prompt of the battery pack opened to the APP to prompt the user through wireless and returns to the vehicle door state and the current temperature of the battery for judgment.
If the vehicle door (four doors and two covers) is in an open state, the user is considered to use the vehicle in advance, heating is stopped, and the remote control controller cancels the prompt that the battery pack is opened and heating is finished through wireless. And then the whole vehicle is powered off.
If the temperature of the battery is greater than or equal to T2 (a calibration amount), the battery is considered to be heated to a proper temperature, the heating can be stopped, and the remote control controller cancels the prompt that the heating of the battery pack is started through wireless. And then the whole vehicle is powered off.
