The AITOP equipment isconnected and controlled by computer, sending instructions andcollecting data; The keyboard can manually operate the equipmentand display parameters and status; Under the command of CPU, theconstant current board has the function of constant current andconstant voltage. When the battery is charged, the two way powersupply converts the AC into 14V DC, and the charging control anddetection of the battery are realized through the constant currentboard. When the battery is discharged, the process is opposite tocharging, the battery voltage is raised to 15V by constant currentplate first, and then the direct current is converted intoalternating current by two-way power supply, which is fed into theAC distribution network of the factory, so as to realize the energyfeedback of battery discharge energy. Energy saving effect isremarkable: the actual measurement shows that the power consumptionof the equipment is reduced by more than 40% compared with thetraditional equipment, the comprehensive power saving rate is morethan 60%, and the power consumption is saved by more than 60%,which saves a lot of costs for battery manufacturers.
