5) accumulator of same nominal voltage is used as data base, using in data base maximum cell batteries rated capacity as Screening conditions, judging whether cell batteries capacity exceedes allows maximum cell batteries capacity, if it is not, choosing, proceeds to step 6), if so, do not select, then proceed to step 7)；；
6) according to cell batteries price, accumulator connection in series-parallel number, incipient fault of the accumulator in normal life cycle Probability and connection cables incipient fault probability are asked for the cost of accumulator first of array, change accumulator cost, accumulator connection Cable cost, array totle drilling cost and array incipient fault probability, and preserve each result of calculation；
7) judge whether accumulator parallel connection number is to allow maximum, if it is not, then proceeding to step 8), if so, then proceed to step 9)；
8) accumulator parallel connection number Jia 1 certainly, and proceeds to step 4)；
9) consider array economy and power supply reliability, calculate the array synthetic coefficient of correspondence accumulator parallel connection number；
10) by comparing the design for choosing array synthetic coefficient minimum, design terminates.
The step 6) specific formula for calculation is as follows：
N=NBHNBV
Y0B=nMB
YDB=KDB(n+NBV-2)MB
YB=Y0B+YHB+YDB
