Step 204, acquiring the running times T1 and T2 of the two galvanic piles and judging the lengths of T1 and T2;
the absolute value of the difference between S1 and S2 is smaller than the preset percentage, which indicates that the difference between the residual performances of the two stacks is not obvious, it is necessary to obtain the running times T1 and T2 of the two stacks and further determine the lengths of T1 and T2 to determine which stack has less performance degradation.
Step 205, determining the galvanic pile with shorter running time as a first galvanic pile, and determining the galvanic pile with longer running time as a second galvanic pile;
the shorter operation time means less performance degradation of the stack, so the stack with the shorter operation time is determined as a first stack, and the stack with the longer operation time is determined as a second stack.
A second part:
at step 206, the first stack is started and operated.
Step 207, judging whether the target power is less than or equal to the rated power of the first galvanic pile;

Step 208, judging whether the operation efficiency of the first galvanic pile is less than the preset efficiency;
and (3) judging whether the operation efficiency of the first galvanic pile is less than the preset efficiency, namely judging whether the operation efficiency of the first galvanic pile can meet the preset required efficiency requirement, if the operation efficiency of the first galvanic pile is more than or equal to the preset efficiency, indicating that the first galvanic pile can meet the preset required efficiency requirement, continuing to execute the step 209, and if the operation efficiency of the first galvanic pile is less than the preset efficiency, indicating that the first galvanic pile can not meet the preset required efficiency requirement, executing the step 210.
Step 209, keeping the single electric pile running;
after the first galvanic pile is judged to meet the required power requirement and the preset required efficiency requirement, the single galvanic pile is kept to operate, so that the performance consumption of the second galvanic pile is saved, and the overall service life is prolonged.
And step 210, starting and operating the second electric pile, and keeping the double electric piles operating.

for another example, the performance percentage S1 of the cell stack 1 and the performance percentage S2, S1 of the cell stack 2 are 62%, and the performance percentage S2 of the cell stack 2 is 60%, the S1 and the S2 are subtracted and an absolute value is obtained, so that 2% is obtained, the preset percentage is 3%, the absolute value of the difference between the S1 and the S2 is smaller than the preset percentage, and the performance attenuation difference between the cell stack 1 and the cell stack 2 is not obvious, so that the running time T1 of the cell stack 1 and the running time T2 of the cell stack 2 need to be obtained for further judgment, the running time T1 of the cell stack 1 is 20 days, the running time T2 of the cell stack 2 is 30 days, and the running time T2 of the cell stack 2 is longer than the running time T1 of the cell stack 1, so that the cell stack 1 is determined as a first cell stack, and the cell stack 2 is determined as a second cell stack.
A second part:
for example, the rated power of the first stack is 80KW, and the target power is 100KW, at this time, the first stack cannot meet the required power requirement, so the second stack needs to be started and operated to meet the required power requirement;
for another example, the rated power of the first stack is 80KW, the target power is 50KW, and at this time, the first stack can meet the required power requirement, and then it is further determined whether the operating efficiency of the first stack meets the preset required efficiency requirement, the operating efficiency of the first stack is 40%, the preset efficiency is 55%, and the first stack cannot meet the preset required efficiency requirement, so that the second stack needs to be started and operated to meet the preset required efficiency requirement;
for another example, the rated power of the first stack is 80KW, and the target power is 50KW, at this time, the first stack can meet the required power requirement, and then it is further determined whether the operating efficiency of the first stack meets the preset required efficiency requirement, the operating efficiency of the first stack is 60%, and the preset efficiency is 55%, and the first stack can also meet the preset required efficiency requirement, so it is enough to keep the first stack operating alone.
In the method of the invention, the first galvanic pile with less performance attenuation is determined by judging the performance percentage and the operation time of the two galvanic piles, the first galvanic pile with less performance attenuation is started and operated firstly to ensure that the residual performance of the two galvanic piles can be kept close, the situation that the residual performance of one galvanic pile is zero and can not be used and the residual performance of the other galvanic pile is much when the residual performance of the other galvanic pile is zero can not be used is ensured, the residual performance of the two galvanic piles is fully utilized, and the second galvanic pile is started and operated to keep the double galvanic piles to operate to meet the power and the efficiency of the use requirement only when the first galvanic pile can not meet the power or the efficiency of the use requirement if the first galvanic pile operated firstly can meet the power and the efficiency of the use requirement, the utilization rate of the residual performance of the double galvanic piles is greatly improved, the influence on the residual performance of the galvanic piles caused by frequent starting and stopping of equipment or low power requirement is weakened, and the service life of the double galvanic piles is effectively prolonged.
