S10: acquiring the temperature of a power battery and the temperature of the environment of the power battery in the electric system;

Including but not limited to a sedan, SUV, MPV, off-road vehicle, pick-up truck, or other power-driven non-rail-borne vehicle.
A hydrogen fuel system refers to a system that converts hydrogen and oxygen into electric energy and water through an electrochemical reaction, and the generated electric energy may be supplied to a driving motor of a vehicle or to an electric system to be stored in a power cell of the electric system. The electric system is one of main power sources for outputting electric energy in the vehicle power supply system, the electric system can charge and store energy through an external charging device, and can acquire and store the electric energy from the hydrogen fuel system, and when the vehicle runs, the hydrogen fuel system and the electric system jointly output power to ensure the power performance of the vehicle.
The power battery thermal management system is a system for performing thermal management on a power battery in an electric system and is mainly used for heating the power battery, and particularly, when the temperature of the power battery is low due to low ambient temperature, the power battery is heated through the power battery thermal management system so as to ensure the output power of the power battery.
Fig. 2 is a schematic diagram of an energy transmission path of a hydrogen fuel cell according to an embodiment of the present application, as shown in fig. 2, in a specific embodiment, after a voltage is generated by an electrochemical reaction, the voltage is transmitted to a DCDC converter, the DCDC converter boosts the voltage and provides the boosted voltage to a power battery or a motor system, the motor system processes the voltage and provides energy for the hydrogen fuel system, and the power battery provides electric energy for the hydrogen fuel system, and the motor system obtains the electric energy and transmits the electric energy to a transmission system to ensure the power performance of a vehicle.
In a specific embodiment, the controller is respectively connected with the hydrogen fuel system, the electric system and the power battery heat pipe system, and in addition, the controller is also connected with an ambient temperature sensor and a power battery temperature sensor, wherein the ambient temperature sensor is used for collecting ambient temperature, and the power battery temperature sensor is used for collecting power battery temperature. Further, the collected ambient temperature and the power cell temperature are transmitted to a controller.
It should be noted that, the execution body of the embodiment of the present application is a controller, and the controller may be a separately configured controller, or may be a whole vehicle controller or a domain controller, which is not limited to this embodiment.
S11: and under the condition that the ambient temperature is less than the preset ambient temperature, if the temperature of the power battery is less than the preset temperature, controlling the hydrogen fuel battery in the hydrogen fuel system to work, and controlling the power battery thermal management system to heat the power battery by using the waste heat generated by the hydrogen fuel battery.
Further, after the power battery temperature and the ambient temperature are obtained, if the ambient temperature is smaller than the preset ambient temperature, it is determined that the power battery temperature is too low due to the fact that the ambient temperature is lower, that is, the power battery temperature is smaller than the optimal working temperature, and at this time, if the vehicle is started, the residual electric quantity (State of Charge, abbreviated as SOC) of the power battery is rapidly reduced, and further the endurance mileage of the vehicle is reduced.
Therefore, according to the technical scheme provided by the embodiment of the application, when the ambient temperature is smaller than the preset ambient temperature and the temperature of the power battery is smaller than the preset temperature, the hydrogen fuel battery is controlled to work, and the power battery thermal management system is controlled to provide the waste heat generated by the hydrogen fuel battery for the power battery to heat.
It can be understood that a great amount of waste heat is generated when the hydrogen fuel cell works, and the temperature of the hydrogen fuel cell is usually between 60 ℃ and 70 ℃ when the hydrogen fuel cell works, and the heat generated by the hydrogen fuel cell is provided for the power cell so as to heat the power cell, so that the temperature of the power cell is quickly increased to be within an optimal working temperature range, and the output power and the discharge capacity of the power cell are further ensured.
Therefore, according to the control method of the vehicle, when the temperature of the power battery is too low in a low-temperature environment, and the output performance and the endurance mileage of the power battery are further affected, namely, the environment temperature is smaller than the preset environment temperature, and the temperature of the power battery is smaller than the preset temperature, the hydrogen fuel battery is controlled to work, and the power battery thermal management system is controlled to provide the residual heat generated by the working of the hydrogen fuel battery for the power battery to heat, so that the temperature of the power battery is quickly increased to an optimal working temperature range, the output power and the discharge capacity of the power battery are guaranteed in the low-temperature environment, and the overall performance of the vehicle is further improved.
In an alternative embodiment, the control method of the vehicle further includes: acquiring a current driving mode of a vehicle and the SOC of a power battery; wherein the driving modes include a first driving mode and a second driving mode, the second driving mode including at least one of a long distance driving mode and a racing driving mode.
It should be noted that the first driving mode is a driving mode different from the second driving mode, and the first driving mode includes a sport driving mode, an economy driving mode, a comfort driving mode, and the like, and may be understood as a normal driving mode or a default driving mode, or may be understood as a driving mode different from a long distance driving mode requiring a high range and a racing driving mode requiring a high power output from the power battery.
Correspondingly, under the condition that the ambient temperature is less than the preset ambient temperature, if the temperature of the power battery is less than the preset temperature, controlling the hydrogen fuel battery in the hydrogen fuel system to work comprises the following steps:
When the driving mode is the second driving mode, the output power of the hydrogen fuel cell is controlled according to the SOC of the power cell.
It can be understood that the requirements on the endurance mileage of the power battery are higher in the long-distance driving mode, while the requirements on the output power of the power battery are higher in the racing driving mode, and the SOC requirements on the power battery are different in different driving modes. Therefore, in the specific embodiment, it is necessary to acquire the current driving mode of the vehicle and the SOC of the power battery in order to control the output power of the hydrogen fuel cell in accordance with the driving mode and the SOC of the power battery.
Specifically, when the ambient temperature is less than the preset ambient temperature and the power battery temperature is less than the preset temperature, and when the hydrogen fuel cells in the hydrogen fuel system are controlled to operate, if the driving mode is the second driving mode, the output power of the hydrogen fuel cells needs to be correspondingly controlled according to the SOC of the power battery, that is, the SOCs of different power batteries correspond to the output powers of different hydrogen fuel cells.
Therefore, the control method of the vehicle provided by the embodiment of the application combines the driving mode of the vehicle and the SOC of the power battery to accurately control whether the power battery is heated, namely, the power battery is heated by the waste heat generated by the hydrogen fuel battery in the scene of needing higher output power of the power battery in the second driving mode such as the long-distance driving mode, the racing driving mode and the like, so that the performance of the power battery is ensured.
On the basis of the above embodiment, as an alternative embodiment, when the second driving mode is the long-distance driving mode, controlling the output power of the hydrogen fuel cell according to the SOC of the power cell includes:
If SOC is more than M1, controlling the output power of the hydrogen fuel cell to be P1, and controlling the hydrogen fuel cell to be closed when the temperature of the power cell is increased to the target temperature;
If M2 is less than SOC and less than or equal to M1, controlling the output power of the hydrogen fuel cell to be P2, and controlling the hydrogen fuel cell to be closed when the temperature of the power cell is increased to the target temperature; wherein P1 is less than P2;
If the SOC is less than or equal to M2, controlling the output power of the hydrogen fuel cell to be P3, and controlling the hydrogen fuel cell to be closed when the temperature of the power cell is raised to the target temperature and the SOC is more than M1; wherein P2 is less than P3, and M1 and M2 are different preset SOC values.
It can be appreciated that after the vehicle is immersed in the vehicle at a low temperature, the temperature of the power battery is too low, the temperature of the power battery is increased by the battery thermal management system and self-heating, the power battery is slow and low-efficiency, and the optimal working temperature (for example, 20-45 ℃ C.) of the power battery is required to be maintained during running, and the battery is required to consume a lot of electric quantity. The SOC of the power cell is used to characterize the remaining charge, and the output power to the hydrogen fuel cell is higher as the SOC of the power cell is smaller.
Therefore, when the ambient temperature is smaller than the preset ambient temperature and the power battery temperature is smaller than the preset temperature, and the output power of the hydrogen fuel battery is controlled according to the SOC of the power battery, if the SOC is larger than M1, the residual electric quantity of the power battery is determined to be more, so that the output power requirement on the hydrogen fuel battery is smaller, the hydrogen fuel battery is controlled to work at the output power P1, at the moment, the residual heat generated by the working of the hydrogen fuel battery is used for heating the power battery, and when the temperature of the power battery is raised to the target temperature, namely, the temperature of the power battery is raised to be within the optimal working temperature interval, the hydrogen fuel battery is turned off.
If M2 < SOC is less than or equal to M1, determining that the residual amount of the SOC is relatively small, and at the moment, the output power of the hydrogen fuel is required to be larger than P1, namely, the hydrogen fuel cell is controlled to work at the output power P2, wherein P2 is more than P1, and similarly, when the temperature of the power cell is increased to the target temperature, namely, the temperature of the power cell is increased to be within the optimal working temperature interval, closing the hydrogen fuel cell.
If the SOC is less than or equal to M2, and the residual quantity of the SOC is minimum at the moment, and the output power of the hydrogen fuel is required to be larger, the hydrogen fuel cell is controlled to work at the output power P3 (P3 is more than P2), and when the temperature of the power cell is raised to the target temperature, the hydrogen fuel cell is controlled to be closed.
It should be noted that, when the ambient temperature is less than the preset ambient temperature and the temperature of the power battery is less than the preset temperature, the power battery needs to be heated by the hydrogen fuel battery at this time, and the electric energy generated by the hydrogen fuel battery at this time can charge the power battery or can be directly provided for the vehicle, which is not limited by the present application.
Of course, in a preferred embodiment, the second driving mode is a long distance driving mode, and the range of the vehicle is more demanding, so the hydrogen fuel cell is operated to charge the power cell in addition to heating the power cell.
It should be further noted that, in the embodiment of the present application, the determination level of SOC and the level setting of the output power of the corresponding hydrogen fuel cell are only an alternative embodiment, and more levels may be set to achieve more precise control, which is not limited to this embodiment.
Therefore, when the second driving mode is the long-distance driving mode, the control method for the vehicle provided by the embodiment of the application can control the hydrogen fuel cell to output corresponding output power according to the SOC of the power cell, so that the temperature of the power cell can be ensured to be raised to an optimal working temperature interval as soon as possible, and the waste of energy sources of the hydrogen fuel cell can be avoided.
In an alternative embodiment, when the second driving mode is the racing driving mode, controlling the output power of the hydrogen fuel cell according to the SOC of the power cell includes:
when the SOC of the power battery is smaller than a first threshold value, controlling the output power of the hydrogen fuel battery to be a preset output power;
When the temperature of the power battery is increased to the target temperature and the SOC of the power battery is larger than a second threshold value, the hydrogen fuel battery is controlled to be closed; wherein the first threshold is less than the second threshold.
In a specific embodiment, when the second driving mode is the racing mode driving mode, the power battery is required to provide high power output, that is, the power battery of the vehicle has the highest output power requirement, and the power battery is often required to reach the maximum output power to meet the acceleration performance requirement of the vehicle. Firstly, the power battery needs self-heating to raise the temperature to an optimal working temperature range, so that the battery can cover large power output, namely, after the SOC of the power battery reaches a certain value, the maximum output power of the power battery can be ensured, however, the self-heating is slow and low-efficiency.
Thus, in some alternative embodiments, if the second driving mode is the racing driving mode and the SOC of the power battery is less than the first threshold, that is, the SOC of the current power battery is insufficient to ensure that the power battery outputs the maximum power, that is, the SOC of the current power battery cannot meet the scene requirement of the racing driving mode, the power battery needs to be charged by the hydrogen fuel battery and the power battery provided by the waste heat generated by the hydrogen fuel battery is needed to heat the power battery.
Specifically, when the SOC of the power battery is smaller than the first threshold, the output power of the hydrogen fuel battery is controlled to be the preset output power, and it can be understood that when the hydrogen fuel battery is controlled to work through the preset output power, the power battery can be charged in time, and the target temperature can be heated at the fastest speed.
After the power battery works for a period of time, when the temperature of the power battery is raised to the target temperature and the SOC of the power battery is larger than a second threshold value, the hydrogen fuel battery is controlled to be closed; wherein the first threshold is less than the second threshold. The second threshold is an SOC value corresponding to the maximum power output of the power battery, for example, when the temperature of the power battery increases to an optimal temperature range and the SOC reaches 50%, the hydrogen fuel battery is turned off.
Therefore, the technical scheme provided by the embodiment of the application has the advantages that the hydrogen fuel cell and the power cell are mixed for use, the hydrogen fuel cell can be fully utilized for generating electricity, the optimal working temperature is higher than that of the power cell, and the power cell can be charged and heated, so that the endurance mileage can be improved to the maximum extent, and the driving experience of a user can be improved.
In some alternative embodiments, the control method of the vehicle further includes:
when the driving mode is the first driving mode under the condition that the ambient temperature is smaller than the preset ambient temperature, the hydrogen fuel cell is controlled to work or be closed according to the SOC of the power cell.
In a specific embodiment, when the ambient temperature is low and the driving mode is the first driving mode, in order to avoid resource waste, the power battery is not heated by the waste heat generated by the hydrogen fuel battery even if the temperature of the power battery is low, and the hydrogen fuel battery is controlled to operate or shut down only according to the SOC of the power battery, that is, whether the hydrogen fuel battery charges the power battery is controlled only according to the SOC of the power battery.
It is to be understood that the first driving mode includes a first driving mode including a sport driving mode, an economy driving mode and a comfort driving mode, and the first driving mode may be understood as a mode in which there is no long distance driving demand and there is no demand for power battery output performance, for example, in a racing driving mode.
Therefore, if the first driving mode is the short-distance driving, the waste heat generated by the hydrogen fuel cell heats the power cell, and the vehicle may already travel to the destination, but the temperature of the power cell is not yet heated to the optimal operation temperature interval, thereby wasting the resources of the hydrogen fuel cell.
Therefore, in some alternative embodiments, when the ambient temperature is less than the preset ambient temperature and the driving mode is the first driving mode, controlling the operation or the shutdown of the hydrogen fuel cell according to the SOC of the power cell includes:
if the SOC of the power battery is larger than a third threshold value, controlling the hydrogen fuel battery to be closed;
if the SOC of the power battery is smaller than the fourth threshold value, controlling the hydrogen fuel battery to work so as to charge the power battery; wherein the third threshold is greater than the fourth threshold.
It is understood that when the SOC is greater than the third threshold value, the remaining amount of electricity of the vehicle is large, and charging by the hydrogen fuel cell is not necessary, and the hydrogen fuel cell is turned off at this time.
