2. System principle
The equipment is connected and controlled by computer, sending instructions and collecting data; The keyboard can manually operate the equipment and display parameters and status; Under the command of CPU, the constant current board has the function of constant current and constant voltage; When the battery is charged, the two-way power supply converts the AC into 12V DC, and the charging control and detection of the battery are realized through the constant current board; When the battery is discharged, the process is opposite to charging. Firstly, the battery voltage is increased to 12V through the constant current board, and then the DC is transformed into AC through the two- way power supply, which is directly fed into the AC distribution network of the factory, so as to realize the energy feedback of battery discharge electric energy. Remarkable power saving effect: according to the actual measurement, the power consumption of the equipment during charging is more than 40% lower than that of traditional equipment, the comprehensive power saving rate is more than 60%, and the power consumption is more than 60%, which saves a lot of costs for battery manufacturer
