and step S30, when the operating temperature of the fuel cell reaches the starting temperature and the fuel cell parameter discharge demand parameter reaches the discharge threshold value, controlling the fuel cell to operate at the third operating power until the starting is completed.
The fuel cell is used for providing energy for the hydrogen fuel automobile, the circulating water pump is used for radiating heat for the fuel cell, when the working temperature of the fuel cell is lower than a first preset threshold, the fuel cell is considered to be in a low-temperature environment at the moment, the starting temperature is a temperature threshold preset for judging that the fuel cell is separated from the low-temperature environment, when the working temperature of the fuel cell is higher than or equal to the starting temperature, the fuel cell is considered to be separated from the low-temperature environment at the moment, the starting temperature is higher than the first preset threshold, and the second working power is higher than the first working power.
In this embodiment, the new energy hydrogen fuel automobile further includes detection component and control assembly, and detection component is used for detecting fuel cell's temperature and transmits temperature information to control assembly, and control assembly is through carrying out analysis and comparing the back through built-in database to temperature information, and control circulating water pump and fuel cell's mode of operation, circulating water pump are used for controlling the temperature to fuel cell for fuel cell can keep in the middle of the suitable operational environment, avoids influencing fuel cell's practical life.
In this embodiment, the operation modes of the fuel cell include a first energy supply mode, a second energy supply mode, and a third energy supply mode, when the operation of the fuel cell is only lower than a first preset threshold, the fuel cell is in the first energy supply mode, and the fuel cell in the first energy supply mode only performs part of power output, and the energy supply of the fuel cell in the first energy supply mode is not higher than 50% of the maximum energy supply of the fuel cell; when the working temperature of the fuel cell rises to be between a first preset threshold value and a starting temperature, the fuel cell is switched to a second energy supply mode, and the energy supply of the fuel cell in the second energy supply mode is not higher than 80% of the maximum energy supply of the fuel cell; when the working temperature of the fuel cell is raised to the starting temperature, the fuel cell is switched to a third energy supply mode, the energy supply of the fuel cell in the third energy supply mode is the maximum energy supply of the fuel cell, and when the fuel cell can operate in the third energy supply mode, the low-temperature starting of the fuel cell can be considered to be completed.
Referring to fig. 1, temperature measurement is performed on a fuel cell before the fuel cell works, an initial temperature of the fuel cell is detected through a detection component and is transmitted to a control component, the initial temperature is compared with a preset temperature through the control component, when the initial temperature is smaller than the preset temperature, the fuel cell is considered to be in a low-temperature environment, in order to ensure the service life of the fuel cell in the low-temperature environment, the fuel cell is ensured not to work under high power until the fuel cell reaches a proper temperature, after the fuel cell works under low power to generate heat, the fuel cell is limited to generate a working mode of a circulating water pump, so that a large amount of heat is accumulated by the fuel cell, the working temperature of the fuel cell in use is increased through the heat, when the fuel cell reaches the starting temperature, the fuel cell can run under full power, and when the fuel cell runs under full power, the fuel cell is considered to have completed low-temperature start.
In this example, the start-up temperature was 20 ℃. When the detection component detects the fuel cell, if the real-time temperature of the fuel cell does not reach 20 ℃, the fuel cell is considered to be still in an environment incapable of full power operation, so that the idle running of the circulating water pump is required to be maintained, heat dissipation is reduced, more heat is accumulated on the fuel cell, and the fuel cell can reach the starting temperature more quickly; when the real-time temperature of the fuel cell reaches 20 ℃, the temperature information of the detection assembly is transmitted to the control assembly, the control assembly judges that the fuel cell reaches the working temperature at the moment, and the fuel cell and the circulating water pump are operated at full power without limiting the power of the fuel cell.

In this embodiment, referring to fig. 2, after step S30, in this embodiment, the detecting component is connected to the control component, and after a certain operation command is sent to the automobile by the user, the control component can read the operation command and compare the power consumption requirement and the discharge amount of the fuel cell for external discharge at this time with the database, so as to avoid the situation that the capacity of the fuel cell is affected when the fuel cell is still operated at full power only when the ambient temperature reaches but the high power of the fuel cell is not actually required. After the power demand is obtained, the maximum rated power of the fuel cell recorded in the database is compared, the external discharge capacity of the fuel cell is a fluctuation range value, and only when the ambient temperature reaches the starting temperature and the upper limit of the external discharge capacity demand of the fuel cell is greater than 50% of the maximum rated power of the fuel cell, the control component determines that the full power operation can be performed at the moment, and then the low-temperature starting process of the fuel cell is completed.
In this embodiment, the detection component is used to detect the operating temperature of the fuel cell, so as to determine whether the operating environment of the fuel cell is in a low-temperature environment, where the starting temperature is a preset temperature at which the fuel cell normally operates at full power without being affected by the ambient temperature, and the operating efficiency and the service life are not affected by the ambient temperature.
In some embodiments, after step S20, further comprising:
step S21, selecting an operating mode of the circulating water pump according to the operating temperature of the fuel cell;
step S21a, when the working temperature of the fuel cell is smaller than a first preset threshold value, controlling the running speed of the circulating water pump to be V1;
step S21b, when the working temperature of the fuel cell is between a first preset threshold value and a starting temperature, controlling the running speed of the circulating water pump to be V2;
step S21c, when the working temperature of the fuel cell is greater than or equal to the starting temperature, controlling the running speed of the circulating water pump to be V3;
wherein, the relation among V1, V2 and V3 is as follows: v3 > V2 > V1.
In this embodiment, referring to fig. 3, when the operating temperature of the fuel cell is less than the first preset threshold, the control component considers that the fuel cell belongs to a low-temperature environment at this time, and needs to increase the temperature of the fuel cell to avoid damage to the fuel cell due to direct full-power operation in the low-temperature environment, and to increase the temperature of the fuel cell, the operating mode of the circulating water pump needs to be defined as a first operating mode, where the operating rate of the circulating water pump is 0 revolutions;
when the operating temperature of the fuel cell is between the first preset threshold value and the starting temperature, the control component considers that the fuel cell starts to generate heat at the moment, because a certain time is needed for temperature rising and lowering objectively, in order to avoid overheating of the fuel cell due to continuous temperature rising after the fuel cell reaches the starting temperature, the control component needs to control the intervention of the circulating water pump in the process, but the operating speed of the circulating water pump cannot be too high to excessively lower the temperature of the fuel cell, so that the operating mode of the circulating water pump is limited to a second operating mode, and the operating speed of the circulating water pump in the second operating mode cannot be higher than 50% of the highest rotating speed of the circulating water pump;
when the working temperature of the fuel cell is greater than or equal to the starting temperature, the control component considers that the fuel cell at the moment is separated from the low-temperature environment, and the current environment temperature can support the fuel cell to perform full-power operation, so that the operating power of the circulating water pump is required to be correspondingly adjusted to be the maximum power to ensure the working efficiency of the whole system at the moment, and the fuel cell or other components are prevented from being overheated.
In this embodiment, referring to fig. 3, when the running speed V1 of the circulating water pump is 0 turns, the first operating mode of the circulating water pump is the first operating mode, that is, when the operating mode of the circulating water pump is the first operating mode, the circulating water pump stops running, so that the fuel cell cannot dissipate heat through the circulating water and thus heat up rapidly.
The operation speed V2 of the circulating water pump is an idle rotation speed, and when the operation speed V2 of the circulating water pump is the operation speed, the circulating water pump is in the second operation mode, and in this embodiment, the idle rotation speed is one eighth of the maximum rotation speed, when the maximum rotation speed is eight thousand rotations, the idle rotation speed is one thousand rotations, and when the maximum rotation speed is four thousand rotations, the idle rotation speed is five hundred rotations.
When the operation rate of the circulating water pump is V3, the operation mode of the circulating water pump is a third operation mode, the operation rate V3 of the circulating water pump is the highest rotation speed of the circulating water pump, and the circulating water pump with the highest rotation speed can enable cooling water to circulate at the highest speed, so that the problems that the service life of the fuel cell is reduced or the use experience of a user is reduced due to the fact that a large amount of heat is accumulated in the use process of the fuel cell are avoided.
The idling rotation speed of the circulating water pump in the second working mode can be changed and adjusted according to the type of the circulating water pump which is actually selected, the idling rotation speed can be any rotation speed between 0 and 50% of the highest rotation speed, and meanwhile, a plurality of rotation speed settings can be set, so that the condition that the circulating water pump is suddenly increased and suddenly decreased due to the rotation speed is avoided.
It can be understood that the circulating water pump is a component on the new energy hydrogen fuel automobile, and the rotation speeds of the circulating water pumps selected for the new energy electric automobiles of different models are different, so that the idle rotation speed of the second working mode can be set according to actual requirements.
It can be understood that the first preset threshold and the starting temperature can be set and adjusted according to actual use requirements, and other preset temperatures can be added according to actual requirements to further refine and adjust the working mode of the fuel cell.

s50, acquiring real-time flow of the circulating water pump, and acquiring cooling efficiency of the circulating water pump;
and step S60, controlling the real-time flow of the circulating water pump according to the heating efficiency and the cooling efficiency.
It can be understood that, in order to ensure that the fuel cell is separated from the low-temperature environment and to prevent damage to the fuel cell, the heating efficiency of the fuel cell needs to be controlled to ensure effective temperature elevation, when the circulating water pump brings cold water through external circulation, the fuel cell is cooled, and the temperature elevation is a continuous process, so that the working efficiency of the fuel cell and the real-time flow of the circulating water pump are required.
In detail, referring to fig. 4, the temperature rise curve of the fuel cell can be obtained by analyzing the operating power of the fuel cell, the temperature rise of the fuel cell is estimated with a threshold value within a certain range, and the temperature drop of the fuel cell is estimated with a threshold value within a certain range according to the real-time flow of the circulating water pump, so that when the fuel cell is still in a low-temperature environment, the temperature rise of the fuel cell needs to be eliminated from the low-temperature environment, and the temperature drop is smaller than the temperature rise.
In this embodiment, circulating water pump still includes valve subassembly, controls circulating water pump's flow through valve subassembly, and when circulating water pump's cooling rate was close to fuel cell's heating efficiency, valve subassembly control circulating water pump's flow reduced, reduces cooling efficiency, and when hydrogen fuel automobile did not break away from low temperature environment, it is higher than cooling efficiency all the time to guarantee to heat efficiency.
In some embodiments, step S60 further comprises:
step S61, determining the temperature change trend of the fuel cell according to the temperature rising efficiency and the temperature reducing efficiency;
step S62, determining the correlation between the working power of the fuel cell and the working power of the circulating water pump according to the temperature change trend of the fuel cell;
step S63, controlling the real-time flow of the circulating water pump according to the correlation between the working power of the fuel cell and the working power of the circulating water pump;
wherein, the heating efficiency is greater than the cooling efficiency.
In this embodiment, referring to fig. 5, when it is required to ensure that the external cold water exchanges heat with the fuel cell, the temperature raising efficiency of the fuel cell is greater than the temperature lowering efficiency of the circulating water pump, so as to maintain a stable temperature raising process.
When the hydrogen fuel automobile breaks away from the low-temperature environment, the fuel cell works at the maximum power, and the circulating water pump also works at the increased power, so that the cooling efficiency is higher than the heating efficiency, but the circulating water pump still needs to be controlled through the valve assembly to prevent the hydrogen fuel automobile from returning to the low-temperature environment.
