Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a control method provided in an embodiment of the present invention, where the embodiment of the present invention is applicable to a situation where a cold start performance of a stack is improved, and the method may be executed by a control device, and specifically includes the following steps:
s110, after the galvanic pile is powered off, identifying the environmental temperature of the environment where the galvanic pile is located;
s120, if the environment temperature meets the cold start condition, determining a standard humidity interval according to the environment temperature;
and S130, adjusting the galvanic pile humidity of the galvanic pile according to the standard humidity interval.
A stack is a cell or battery, such as a fuel cell that obtains electrical energy through the combustion reaction of hydrogen and oxygen. The cold start refers to the condition that the galvanic pile is directly electrified and started without preheating, the cold start condition can allow the galvanic pile to be directly started without preheating, the cold start condition can refer to the temperature of the environment where the galvanic pile is located, and the cold start condition can be set manually according to requirements or empirical values and can also be adjusted and determined according to a large number of tests. The standard humidity range refers to a humidity range that allows the stack to have good cold start-up performance. The standard humidity interval can be set manually according to requirements or empirical values, and can also be adjusted and determined according to a large number of tests, and the standard humidity intervals corresponding to different environmental temperatures are generally different.
Illustratively, the stack humidity of the stack may be determined by direct or indirect measurement.
In a specific implementation mode, the humidity sensor is arranged in the environment where the galvanic pile is located, and then the galvanic pile humidity of the galvanic pile is obtained according to the measurement data of the humidity sensor.
In another specific implementation, the stack humidity of the stack may be determined by measuring a humidity-related attribute of the stack and according to a conversion relationship between the humidity-related attribute and the stack humidity. Of course, in order to simplify the calculation, the humidity-related attribute can be directly adopted to replace the galvanic pile humidity, and then the adjustment of the galvanic pile humidity is realized by adjusting the humidity-related attribute. Optionally, the humidity-related property of the stack may include, but is not limited to, a stack resistance value. Specifically, after the galvanic pile is powered off, the control device identifies the current environment temperature of the galvanic pile, if the environment temperature meets the set cold start condition, the range value of the standard humidity range is set according to the current environment temperature, and the humidity of the galvanic pile after the galvanic pile is powered off is adjusted according to the range value.
In a specific example, after the electric pile is powered off, the control device detects that the environment temperature of the electric pile is about 0 ℃, and the electric pile at the moment meets the cold start condition. In order to enable the galvanic pile to be in a better performance state when the galvanic pile is in the next cold start, a user can adjust the humidity of the current galvanic pile to be in a proper range. For example, the cell stack may be dried or humidified to this humidity range by purging with an air compressor or humidifying.
It should be noted that, in order to keep the adjusted stack humidity within a proper humidity range during the next cold start, in an optional embodiment, after the stack humidity of the stack is adjusted to a standard humidity range, the stack inlet and outlet valves are closed, so as to ensure that the internal humidity of the stack remains unchanged.
According to the technical scheme of the embodiment of the invention, the humidity of the galvanic pile is changed according to the environmental temperature of the galvanic pile after power off, so that the galvanic pile is in a proper humidity environment when being cold started next time, the galvanic pile is favorable for being quickly started, the discharge efficiency is improved, the problem of poor cold starting performance of the galvanic pile in a low-temperature environment is solved, the galvanic pile is in a proper humidity after power off to improve the performance of the galvanic pile during cold start, the use efficiency of the galvanic pile is further improved, and the use experience of a user is improved.
Example two
The embodiment of the present invention is optimized based on the technical solutions of the foregoing embodiments, and fig. 2 is a flowchart of a control method provided in the second embodiment of the present invention, and the embodiment of the present invention is applicable to a situation of improving a cold start performance of a stack, and the method may be executed by a control device, and specifically includes the following steps:
s210, after the galvanic pile is powered off, identifying the environmental temperature of the environment where the galvanic pile is located;
s220, determining a reference temperature of the galvanic pile according to the environment temperature;
s230, determining the standard humidity interval according to the reference temperature of the galvanic pile;
s240, adjusting the galvanic pile humidity of the galvanic pile according to the standard humidity interval.
The stack reference temperature is a temperature that enables the stack to perform better at cold start. For example, when the ambient temperature is below-20 ℃, the stack reference temperature may be set to-10 ℃, and when the ambient temperature is between 0 ℃ and-20 ℃ of the freezing temperature, the stack reference temperature may be set to 5 ℃. Therefore, after power is cut off, the electric pile is finally at the electric pile reference temperature and the humidity corresponding to the temperature, so that the cold start performance of the electric pile can be effectively improved.
Therefore, after the electric pile is powered off, the control device firstly detects the current ambient temperature, the reference temperature after the electric pile is powered off and the corresponding humidity of the reference temperature can be determined according to the ambient temperature, and the standard humidity interval of the electric pile is determined based on the reference temperature, so that the humidity of the electric pile is controlled to be in the interval range through the air compressor or the humidifier, and the performance of the electric pile during the next cold start is improved.
In an alternative embodiment, the determining the standard humidity interval according to the stack reference temperature may include: and determining a standard resistance value interval corresponding to the standard humidity interval according to the reference temperature of the galvanic pile. Correspondingly, the adjusting the stack humidity of the stack according to the standard humidity interval may include: detecting the current resistance value of the galvanic pile in real time; and if the current resistance value belongs to the complementary collection interval of the standard resistance value interval, adjusting the humidity of the galvanic pile until the adjusted resistance value belongs to the standard resistance value interval.
The standard resistance interval refers to the variation range of the resistance when the galvanic pile is in the standard humidity interval, and as the resistance of the galvanic pile is continuously reduced along with the increase of the humidity, a certain corresponding relation exists between the standard resistance interval and the standard humidity interval, so that the method for detecting the humidity variation by detecting the resistance variation of the galvanic pile is an optional method.
Specifically, after the standard resistance interval corresponding to the standard humidity interval is determined, after the galvanic pile is powered off, the control device detects the resistance change of the galvanic pile in real time, and when the resistance of the galvanic pile is not in the previously determined standard resistance interval, the control device controls the air compressor to blow the galvanic pile dry and/or controls the humidifier to humidify the galvanic pile, so that the resistance of the galvanic pile can be in the standard resistance interval, and at the moment, the humidity of the galvanic pile is also in the standard humidity interval. Wherein, the humidifier, namely the galvanic pile humidifying device, can be an ultrasonic humidifier or a direct evaporation humidifier; the air compressor, i.e. the air compressor, may be a scribe-and-break compressor, or may be a rotary compressor, and the humidity control device is not limited in the embodiments of the present invention.
Through the mode that will detect humidity conversion and detect resistance, carry out humidity to the galvanic pile among the electricity process and detect to find the next cold start performance that suitable humidity interval kept the galvanic pile, reduced the degree of difficulty that detects humidity, can also be better carry out accurate control according to resistance change to air compressor machine and humidifier.
In one embodiment, if the current resistance value belongs to a complementary region of the standard resistance value region, adjusting the stack humidity of the stack until the adjusted resistance value belongs to the standard resistance value region may include: if the current resistance value is larger than the maximum resistance value in the standard resistance value interval, controlling a humidifier to humidify the galvanic pile so as to update the current resistance value; if the current resistance value is smaller than the minimum resistance value in the standard resistance value interval, controlling an air compressor to purge the galvanic pile so as to update the current resistance value; and if the current resistance value belongs to the standard resistance value interval, stopping the updating operation of the current resistance value.
Updating the resistance value means changing the resistance value of the stack by controlling the humidity. The updating operation of the current resistance value refers to the operation of increasing and decreasing the humidity, namely humidifying of a humidifier or purging of an air compressor.
Specifically, the numerical range of the standard resistance interval corresponding to the standard humidity interval has the maximum value and the minimum value, and when the current resistance value of the galvanic pile detected by the control device in real time is greater than the maximum resistance value of the standard resistance interval, the current humidity of the galvanic pile is known to be low due to the fact that the current resistance is too large, so that the control device controls the humidifier to humidify the galvanic pile, the humidity of the galvanic pile is increased, and the resistance of the galvanic pile is reduced. When the current resistance value of the galvanic pile detected by the control device in real time is smaller than the minimum resistance value within the standard resistance value range, the current humidity of the galvanic pile is known to be higher by the fact that the current resistance is too small, so that the control device controls the air compressor to purge the galvanic pile, the humidity of the galvanic pile is reduced, and the resistance is increased. When the current resistance value of the galvanic pile detected by the control device in real time is in the standard resistance value interval, the humidity is proved to be appropriate at the moment, and the operation of increasing and decreasing the humidity of the galvanic pile is not needed, so that the humidifying operation or the purging operation of the galvanic pile is stopped.
Illustratively, the range of the currently determined standard resistance range is 85-95 Ω, and if the resistance of the galvanic pile is detected to be 120 Ω, the control device controls the humidifier to humidify, and during this period, the resistance of the galvanic pile is continuously detected, and when the resistance decreases to less than 95 Ω (but not equal to or less than 85 Ω), the humidifying operation on the galvanic pile is stopped. Similarly, if the currently detected resistance value of the galvanic pile is 60 Ω, the air compressor is controlled by the control device to purge the galvanic pile, the resistance value of the galvanic pile is continuously detected during the period, and when the resistance value is increased to be greater than 85 Ω (but not greater than or equal to 95 Ω), the purging operation on the galvanic pile is stopped. It should be noted that each resistance value in the standard resistance interval is only used as a specific example of the standard resistance interval, and may be adjusted according to actual conditions, which should not be construed as a specific limitation to the embodiment of the present invention.
According to the implementation mode, the humidity can be flexibly controlled according to the resistance value of the current galvanic pile detected in real time, the difficulty of controlling purging and humidifying after power off is reduced by adjusting the humidity according to the resistance, the humidity is controlled within the range of the standard humidity range, and the performance of the cold start of the galvanic pile at the next time is further improved.
In an alternative embodiment, before the adjusting of the stack humidity of the stack according to the standard humidity interval, the method may further include: and controlling the hydrogen path and the air compressor to purge the electric pile until the resistance value of the electric pile is greater than a preset resistance threshold value.
The hydrogen path refers to the path of hydrogen in a hydrogen fuel cell, which can help reduce humidity by feeding hydrogen. The preset resistance threshold is set artificially according to the resistance value corresponding to the humidity of the galvanic pile, and a higher resistance value corresponding to a lower humidity can be selected as the preset resistance threshold. Specifically, if the current galvanic pile belongs to a hydrogen fuel cell, a higher resistance threshold value can be set (for example, the resistance threshold value can be set to 120 Ω), and the control device controls the hydrogen gas circuit and the air compressor to purge the galvanic pile, so that the humidity of the galvanic pile is reduced, the resistance value of the galvanic pile can be increased, and when the resistance value reaches the preset resistance threshold value of 120 Ω, purging of the galvanic pile is stopped.
According to the embodiment, the humidity of the galvanic pile is reduced through the purging operation of the hydrogen gas circuit and the air compressor on the galvanic pile, so that the galvanic pile is in a dry state, the subsequent humidity of the galvanic pile is convenient to further adjust, and the galvanic pile after power off is cooled.
In an alternative embodiment, the detecting the current resistance value of the stack in real time may include: and if the temperature of the galvanic pile is not greater than the reference temperature of the galvanic pile, controlling to detect the current resistance value of the galvanic pile in real time.
Specifically, in the foregoing embodiment, the hydrogen gas path and the air compressor purge the galvanic pile, the galvanic pile can be cooled while drying the galvanic pile, and when the temperature is reduced to a reference temperature of the galvanic pile not greater than that set in the foregoing embodiment, the control device starts real-time detection of the resistance value of the galvanic pile.
For example, after power is off, the temperature of the galvanic pile is high and can reach 70 ℃, for example, the control device controls the hydrogen gas circuit and the air compressor to purge the galvanic pile, so that the temperature and the humidity of the galvanic pile are reduced, the resistance of the galvanic pile is monitored in real time when the preset reference temperature of the galvanic pile is reduced, and the humidity of the galvanic pile can be laid for subsequent adjustment.
In an alternative embodiment, the controlling a humidifier to humidify the stack if the current resistance value is greater than the maximum resistance value in the standard resistance value interval may include: and if the current resistance value is larger than the maximum resistance value in the standard resistance value interval, controlling a humidifier to humidify the galvanic pile according to the difference value of the current resistance value and the maximum resistance value. In an alternative embodiment, if the current resistance value is smaller than the minimum resistance value in the standard resistance value interval, the controlling an air compressor to purge the stack may include: and if the current resistance value is smaller than the minimum resistance value in the standard resistance value interval, controlling an air compressor to purge the electric pile according to the difference value between the current resistance value and the minimum resistance value.
Specifically, the resistance value of the current resistor is compared with the standard resistance value range, if the current resistance value is larger than the maximum resistance value of the standard resistance value range, the difference value between the current resistance value and the maximum resistance value is calculated, the humidification intensity of the humidifier for humidification can be controlled according to the difference value, for example, when the resistance value difference value is large, the humidifier is controlled to be started to conduct high-power humidification quickly, and when the resistance value difference value is small, the humidifier is controlled to be started to conduct low-power humidification slowly, so that the humidification precision is improved. Similarly, if the current resistance value is smaller than the minimum resistance value in the standard resistance value interval, the difference between the current resistance value and the minimum resistance value is calculated, the purging intensity of the air compressor is controlled according to the difference, for example, when the resistance value difference is large, the air compressor is controlled to be started with large power to perform rapid purging to reduce humidity, and when the resistance value difference is small, the air compressor is controlled to be started with small power to perform slow purging, so that the drying precision is improved.
According to the method, the difference degree between the current humidity of the galvanic pile and the standard humidity interval is effectively reflected by converting the detected galvanic pile humidity into the difference value between the detected current resistance value and the maximum value or the minimum value of the standard resistance value interval, so that the humidifier and/or the air compressor are adopted to adjust the galvanic pile humidity according to the difference degree, the convenience of adjusting the galvanic pile humidity is improved, the situation that the standard humidity interval cannot be reached even if alternate humidification or blow-drying is carried out is avoided, and the humidity adjusting efficiency is improved.
In one specific implementation, the humidity increase amount may be determined according to a difference between the current resistance value and a maximum resistance value in the standard resistance value interval; determining a humidification adjustment parameter according to the total humidity increase amount; wherein the humidification adjusting parameters comprise humidification times and/or single humidification quantity; and controlling a humidifier to humidify the galvanic pile according to the humidification adjusting parameters so as to increase the humidity of the galvanic pile.
In another specific implementation, the humidity reduction amount may be determined according to a difference between the current resistance value and a minimum resistance value in the standard resistance value interval; determining a drying adjustment parameter according to the total humidity reduction amount; wherein the dryness-increasing adjustment parameter comprises the purging times and/or the single purging quantity; and controlling an air compressor to purge the galvanic pile according to the drying adjustment parameters so as to reduce the humidity of the galvanic pile.
Further, when the resistance value detected by the control device accords with a standard resistance value interval, the humidity of the galvanic pile is judged to be in the standard humidity interval, the performance of the next cold start is improved, and the inlet and outlet valves of the galvanic pile are closed to ensure that the water content in the galvanic pile is not changed (namely, the humidity is kept), so that the power-off process is completed.
According to the embodiment of the invention, the change of the humidity of the galvanic pile is reflected by detecting the resistance of the galvanic pile in real time, meanwhile, the humidification or the blow-drying of the galvanic pile is controlled more simply and effectively according to the difference value between the current resistance and the standard resistance interval, and the humidity of the galvanic pile after power-off is accurately controlled within the preset humidity range, so that the galvanic pile has better performance when being cold-started next time, and the use experience of a user on the galvanic pile is further improved.
