It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.
In an exemplary embodiment, as shown in fig. 2, a method for controlling start-stop of a galvanic pile is provided, and the method is applied to the server 104 in fig. 1 for illustration, and includes the following steps 202 to 206. Wherein:
step 202, obtaining a hot standby time corresponding to the conversion of the electric pile between the working state and the high Wen Daiji state, and obtaining a cold start time corresponding to the conversion of the electric pile between the working state and the low-temperature standby state.
A stack, also called a cell stack, is a device that converts chemical energy stored in a cell into electrical energy through a series of chemical reactions. Because the chemical reaction needs a certain reaction temperature, the working temperature of the electric pile when in work needs not to be lower than the reaction temperature, so that the electric pile can be started normally. When the electric pile is not required to be started, namely, the electric pile is in a standby state, how to control the temperature of the electric pile so that the energy consumption is the lowest and the service life of the electric pile is the longest is a problem to be solved.
The high temperature standby state means that the stack is in a high temperature state lower than the reaction temperature when in standby, and the energy consumption of the stack is higher in a state of high Wen Daiji, but the start-up speed of the stack in a state of high Wen Daiji is very fast. In addition, long periods of time in the high Wen Daiji state can affect the life of the stack.
The low-temperature standby state means that the stack is in a low-temperature state when in standby, the temperature of the stack at the time may be room temperature or far lower than the reaction temperature, and the energy consumption of the stack in the low-temperature standby state is not high in a state of Wen Daiji, but the start time of the stack in the low-temperature standby state is long and the start speed is slow. In addition, repeated switching of the stack between the operating state and the low-temperature standby state can affect the life of the stack.
Alternatively, the hot standby time corresponding to the transition of the electric pile between the working state and the high Wen Daiji state and the cold start time corresponding to the transition of the electric pile between the working state and the low-temperature standby state may be obtained through actual measurement, and the hot standby time and the cold start time may also be obtained through analysis of the historical state.
And 204, if the hot standby time is greater than or equal to the cold start time, respectively acquiring a heat energy consumption value of the electric pile in the hot standby time and a cold energy consumption value of the electric pile in the cold start time, and comparing the heat energy consumption value and the cold energy consumption value.
The energy consumption value represents the energy consumption of the electric pile in the standby state and the energy consumption required by the startup from the standby state. The heat energy consumption represents a standby energy consumption value in a high Wen Daiji state and a start energy consumption value in a hot standby state, and the cold energy consumption value represents a standby energy consumption value in a low-temperature standby state and a start energy consumption value in a cold start state of the stack.
As described above, since both hot standby and cold start have certain disadvantages, the hot standby and cold start are balanced in the start-stop control of the electric pile, so as to realize the control of the working state of the electric pile. In the embodiment, when the hot standby time is greater than or equal to the cold start time, the heat energy consumption value and the cold energy consumption value of the electric pile are obtained, and the electric pile standby scheme with the lowest energy consumption is determined by comparing the energy consumption values.
And 206, under the condition that the heat energy consumption value is larger than the cold energy consumption value, acquiring the energy consumption ratio of the heat energy consumption value and the cold energy consumption value, and determining the working state of the electric pile according to the energy consumption ratio.
The energy consumption ratio is obtained by dividing the heat energy consumption value by the cold energy consumption value under the condition that the heat energy consumption value is larger than the cold energy consumption value, and the energy consumption ratio is larger than one because the heat energy consumption value is larger than the cold energy consumption value. According to the embodiment, the working state of the electric pile is determined according to the energy consumption ratio according to the analysis of the energy consumption ratio, the control of the standby state of the electric pile can be optimized, and the start-stop control scheme with the lowest energy consumption and the most economical performance is obtained.
In the above-mentioned electric pile start-stop control method, obtain the electric pile and change the correspondent hot standby time between working condition and high Wen Daiji state, and obtain the electric pile and change the correspondent cold start time between working condition and low-temperature standby state; if the hot standby time is greater than or equal to the cold start time, respectively acquiring a heat energy consumption value of the electric pile in the hot standby time and a cold energy consumption value of the electric pile in the cold start time, and comparing the heat energy consumption value and the cold energy consumption value; and under the condition that the heat energy consumption value is larger than the cold energy consumption value, acquiring the energy consumption ratio of the heat energy consumption value to the cold energy consumption value, and determining the working state of the electric pile according to the energy consumption ratio. When the start-stop control of the electric pile is performed, the time for switching the electric pile to a high Wen Daiji state and to a low-temperature standby state is firstly judged, whether the electric pile needs to be switched to the low-temperature standby state is determined, and when the hot standby time is more than or equal to the cold start time, the heat energy consumption value in the hot standby and the cold energy consumption value in the cold start are judged, and when the heat energy consumption value is more than the cold energy consumption value, the energy consumption ratio between the heat energy consumption value and the cold energy consumption value is further analyzed, so that the working state of the electric pile is controlled. The pile control method of the embodiment has simple logic, avoids other complicated judging processes, and can improve the control efficiency of pile start-stop. Meanwhile, the application realizes the control of the electric pile by comparing the heat energy consumption value and the cold energy consumption value, can realize the optimal control of energy consumption during the start-stop control of the electric pile, reduces the energy consumption during standby, can also improve the service life of the electric pile, and has high reliability.
In one exemplary embodiment, obtaining a hot standby time corresponding to a transition of a stack between an operating state and a high Wen Daiji state and obtaining a cold start time corresponding to a transition of a stack between an operating state and a low temperature standby state includes: when the electric pile is switched between a working state and a high Wen Daiji state, acquiring the electric pile non-power output time, and taking the non-power output time as the hot standby time; when the electric pile is switched between the working state and the low-temperature standby state, the cold start time is determined according to the cooling time of the electric pile from the working state to the low-temperature standby state and the heating time of the electric pile from the low-temperature standby state to the working state.
When the stack is in the high Wen Daiji state, the temperature of the stack is high, but the stack is in the open state by opening the switch for external output of the stack, so that the stack in the high Wen Daiji state does not generate electric energy, does not output power, and the non-power output time can be used as the thermal standby time of the stack by predicting the time when the stack does not output power.
When the electric pile is in the low-temperature standby state, the cold start time of the electric pile is longer, so that the cold start time can be obtained in the same mode as the hot standby time, and the cold start time can be determined according to the cooling time of the electric pile from the working state to the low-temperature standby state and the heating time of the electric pile from the low-temperature standby state to the working state. The heating time from the low-temperature standby state to the working state can be obtained through the set heating rate and the difference between the reaction temperature and the low temperature when the galvanic pile is started, and the heating rate is customized according to the actual scene, for example, 2 ℃/min.
Further, in one embodiment, the method further comprises: and if the hot standby time is less than the cold start time, controlling the electric pile to enter a high Wen Daiji state.
And when the acquired hot standby time is smaller than the cold start time, directly controlling the electric pile to enter a high Wen Daiji state. In general, the loss of the service life of the electric pile caused by the hot standby is smaller than that of the service life of the electric pile caused by the cold start in the same time, so that the electric pile is controlled to be in hot standby in the hot standby time which is smaller than that of the cold start, the energy consumption of the electric pile is saved, the attenuation of the electric pile is reduced, and the service life of the electric pile is prolonged.
In one embodiment, obtaining a thermal energy consumption value of the electric pile in a hot standby time and a cold energy consumption value of the electric pile in a cold start time includes: determining a heat energy consumption value according to a heat standby energy consumption value of the electric pile in a high Wen Daiji state, a heat starting energy consumption value of the electric pile in a state of converting from a high Wen Daiji state to a working state and a standby attenuation of the electric pile in a high Wen Daiji state; and determining the cold energy consumption value according to the cold standby energy consumption value of the electric pile in the low-temperature standby state, the cold start energy consumption value of the electric pile when the electric pile is converted from the low-temperature standby state to the working state and the start attenuation of the electric pile in the cold start.
As described above, the power consumption of the stack at the start-up and stop includes the sum of the power consumption at the standby state and the power consumption required at the start-up. In addition, for different standby states, the embodiment also updates the energy consumption of the electric pile through the influence of the standby state on the service life of the electric pile.
For example, the life of the stack is affected by a long-time high temperature of the stack in the high Wen Daiji state, and the standby attenuation effect is converted into energy consumption when calculating the heat energy consumption value, wherein the standby attenuation energy consumption can be obtained by multiplying the heat standby time by the effect factor A of the unit heat standby time on the life of the stack, and A can be expressed as a%/h.
Meanwhile, cold start of the pile in a low-temperature standby state can also influence the service life of the pile, the start attenuation influence is also converted into energy consumption when a cold energy consumption value is calculated, the start attenuation energy consumption can be obtained by multiplying the cold start times and a factor B of influence of single cold start on the service life of the pile, and B can be expressed as b%/times. If a and b are positive values, the service life of the electric pile can be correspondingly reduced by hot standby and cold starting, and the reduced service life is converted into the energy consumption of the working time, which is equivalent to updating the heat energy consumption value and the cold energy consumption value.
Further, in one embodiment, the method further comprises: and if the hot standby time is greater than or equal to the cold start time and the heat consumption value is less than or equal to the cold energy consumption value, controlling the electric pile to enter a high Wen Daiji state.
When the hot standby time is equal to or longer than the cold start time but the heat consumption value is equal to or shorter than the cold energy consumption value, the hot standby time is longer but the energy consumption is lower, so that the electric pile is controlled to enter a high Wen Daiji state to reduce the energy consumption.
In one embodiment, determining the operating state of the stack based on the power consumption ratio includes: if the energy consumption ratio is smaller than the lower limit of the preset ratio, controlling the electric pile to enter a high Wen Daiji state; if the energy consumption ratio is larger than the upper limit of the preset ratio, controlling the electric pile to enter a low-temperature standby state; if the energy consumption ratio is greater than or equal to the lower limit of the preset ratio and less than or equal to the upper limit of the preset ratio, in the limit of the hot standby times, when the energy consumption ratio of the control sub-period meets the energy consumption condition, the electric pile is controlled to enter a high Wen Daiji state, and under other conditions, the electric pile is controlled to enter a low-temperature standby state, wherein the hot standby times are related to the cold start predicted value and the cold start preset threshold value.
Wherein, because the heat energy consumption value is larger than the cold energy consumption value, the energy consumption ratio is larger than one. And setting a preset ratio upper limit and a preset ratio lower limit for the energy consumption ratio, judging the energy consumption ratio, the preset ratio upper limit and the preset ratio lower limit, and controlling the electric pile to enter a high Wen Daiji state if the energy consumption ratio is smaller than the preset ratio lower limit. At this time, it can be understood that although the heat energy consumption value is larger than the cold energy consumption value, the difference between the heat energy consumption value and the cold energy consumption value is small, so that the energy consumption ratio is smaller than the lower limit of the preset ratio, and the energy consumption can be saved by controlling the electric pile to enter the high Wen Daiji state.
If the energy consumption ratio is larger than the upper limit of the preset ratio, the difference between the heat energy consumption value and the cold energy consumption value is excessively large, and if the control pile enters a high Wen Daiji state, more consumption is generated, so that the control pile enters a low-temperature standby state.
If the energy consumption ratio is between the upper limit and the lower limit of the preset ratio, the energy consumption ratio is larger than or equal to the lower limit of the preset ratio and smaller than or equal to the upper limit of the preset ratio, and the electric pile is controlled to enter a low-temperature standby state according to the principle. However, the number of cold starts of the electric pile in the control period is limited, and if the number of cold starts exceeds the preset threshold value of cold starts, the service life of the electric pile is greatly reduced, so that the hot standby number is determined by the predicted value of cold starts and the preset threshold value of cold starts in order to consider both the energy consumption and the service life of the electric pile. The control period is divided into a plurality of control subcycles, when the energy consumption ratio of the control subcycles meets the energy consumption condition, the electric pile is controlled to enter a high Wen Daiji state, and the electric pile is controlled to enter a low-temperature standby state under the other conditions, so that the cold start times of the electric pile are within a cold start preset threshold value, and the economical efficiency of the fuel cell system is also ensured.
For example, assume that the preset ratio upper limit of the power consumption ratio is 110%, the preset lower limit is 102%, and the cold start preset threshold m is 10 times. When the heat energy consumption value is larger than the cold energy consumption value, dividing the heat energy consumption value by the cold energy consumption value to obtain an energy consumption ratio n, wherein n is larger than 1.
Assuming that n is 1.01, the heat energy consumption is only 1% more than the cold energy consumption, and the electric pile is controlled to enter a state of high Wen Daiji at the moment so as to reduce the cold start times of the electric pile.
Assuming n is 1.11, which means that the heat energy consumption is higher than the cold energy consumption, and the lower energy consumption value can be obtained by controlling the electric pile to enter the low-temperature standby state.
And when n is between 102% and 110%, judging the adjustment state of the electric pile by combining with a cold start preset threshold value. Assuming that the cold start needs 12 times in the control period predicted at this time and the preset cold start preset threshold is 10 times, the number of times of two times of cold start is increased to be adjusted to be hot standby, and the most economical hot standby mode is selected by judging the energy consumption ratio in the control sub-period.
Taking the control period as one year, taking the control sub-period as a quarter as an example, taking the energy consumption ratio of 102-110% of the first quarter as a basis, judging a new energy consumption ratio range in the second quarter, and taking the smallest energy consumption ratio compared with the first quarter, wherein the heat energy consumption value is higher than the cold energy consumption value at the moment, the stack is not controlled to enter a low-temperature standby state, but enters a high Wen Daiji state. And the third quarter is the same as the third quarter, and the lowest energy consumption ratio is judged and selected, wherein the third quarter is judged to be the energy consumption ratio of all 102-110% of the first quarter and the second quarter. If the third quarter has no proper value, the fuel cell system is prolonged to the fourth quarter, and if the fourth quarter has no proper value, the lowest energy consumption ratio predictable in the fourth quarter is taken, so that the cold start times can be ensured to be within a cold start preset threshold value, and the economy of the fuel cell system can be ensured.
Further, in one embodiment, the method further comprises: when the control electric pile enters a low-temperature standby state, judging whether the cold start times of the electric pile are smaller than a cold start preset threshold value or not; if the cold start times are smaller than the cold start preset threshold, controlling the electric pile to enter a low-temperature standby state, and updating the cold start times to obtain new cold start times; if the cold start times are greater than or equal to the cold start preset threshold, the current working state of the electric pile is controlled, the candidate electric pile is controlled to enter a low-temperature standby state, and the cold start times of the candidate electric pile are smaller than the corresponding cold start preset threshold.
For example, before the stack enters the low-temperature standby state, the number of times of cold start of the stack at the end needs to be checked, if the number of times of cold start of the stack is not greater than a preset threshold m of cold start, the stack is controlled to enter the low-temperature standby state to perform cold start, and the number of times of cold start of the stack is updated to be one plus the number of times of cold start.
If the cold start times of the electric pile reach the cold start preset threshold value m, the electric pile is not suitable for entering a low-temperature standby state for cold start for the purpose of protecting the service life of the electric pile, the working state of the electric pile is kept, the candidate electric pile is controlled to enter the low-temperature standby state, and the candidate electric pile selects the electric pile with the cold start times not reaching the cold start preset threshold value for cold start by inquiring other electric piles with the cold start times not reaching the cold start preset threshold value.
In an exemplary embodiment, first, it is primarily determined whether the stack needs to consider cold start according to the magnitude relation between the hot standby time and the cold start time, and only when the hot standby time is greater than or equal to the cold start time, the stack is considered to be controlled to enter the low-temperature standby state, otherwise, the stack is directly controlled to enter the high Wen Daiji state. When cold start is considered, checking and judging the energy consumption condition, and controlling the electric pile to enter a high Wen Daiji state when the heat energy consumption value is not more than the cold and hot energy consumption value; when the heat energy consumption value is larger than the cold energy consumption value, the cold start is considered to be selected, but at the moment, whether the historical cold start times of the electric pile reach a cold start preset threshold value or not is checked, the cold start is performed only if the historical cold start times of the electric pile do not reach the cold start preset threshold value, if the historical cold start times of the electric pile reach the cold start preset threshold value, the electric pile is enabled to continue to work, and then the electric pile with other cold start times not reaching the cold start preset threshold value is subjected to cold start.
For example, when the current cold start preset threshold value of the electric pile is set to m=100 and the electric pile is shut down, if the hot standby time of the electric pile is determined to be greater than or equal to the cold start time, and then the heat energy consumption value of the electric pile is determined to be greater than the cold energy consumption value, the cold start times of the electric pile are checked, if the cold start times of the electric pile are found to be 100, that is, the cold start preset threshold value is reached, the working state of the electric pile is maintained, and cold start work is considered to be performed on the rest electric pile.
In one embodiment, as shown in fig. 3, a method for controlling start-stop of a galvanic pile is provided, including the following steps 302 to 312, wherein:
step 302, obtaining a hot standby time corresponding to the conversion of the electric pile between the working state and the high Wen Daiji state, and obtaining a cold start time corresponding to the conversion of the electric pile between the working state and the low-temperature standby state.
And step 304, judging whether the control of the electric pile to enter the low-temperature standby state is needed to be considered according to the hot standby time and the cold starting time.

And 306, if the hot standby time is greater than or equal to the cold start time, acquiring a heat energy consumption value and a cold energy consumption value.
The energy consumption value comprises an energy consumption value during standby and an energy consumption value during starting, the heat energy consumption value further comprises equivalent energy consumption corresponding to standby attenuation during hot standby, and the cold energy consumption value further comprises equivalent energy consumption corresponding to starting attenuation during cold starting.
And step 308, judging whether the control of the electric pile to enter a low-temperature standby state is needed to be considered according to the heat energy consumption value and the cold energy consumption value.
If the heat energy consumption value is smaller than or equal to the cold energy consumption value, the power stack is controlled to enter a high Wen Daiji state.
Step 310, if the heat energy consumption value is greater than the cold energy consumption value, judging whether to consider controlling the electric pile to enter a low-temperature standby state according to the energy consumption ratio of the heat energy consumption value and the cold start times of the electric pile.
If the energy consumption ratio is smaller than the lower limit of the preset ratio, controlling the electric pile to enter a high Wen Daiji state; and if the energy consumption ratio is larger than the upper limit of the preset ratio, controlling the electric pile to enter a low-temperature standby state.
If the energy consumption ratio is larger than or equal to the lower limit of the preset ratio and smaller than or equal to the upper limit of the preset ratio, the hot standby time is determined according to the cold start time and the cold start preset threshold, the electric pile is controlled to enter a high Wen Daiji state when the energy consumption ratio meets the energy consumption condition, and the electric pile is controlled to enter a low-temperature standby state under the other conditions.
