3.Bidirectional AC/DC inverter module;
4.Tray-type automatic clamping and clamping (cylinder) mode.
2.System structure and working principle
2.1System Composition
1.Lithium battery is converted into capacity equipment.
2.Computer with USB interface (bring your own).
3.USB to 485 interface converter or five types of communication lines and crystal heads.
4.Battery scanning system.
5.Shengchuang product software.
2.2System principle
The equipment is connected and controlled by a computer to send commands and collect data; the keyboard can manually operate the equipment to display parameters and status; the constant current board is commanded by the CPU and has constant current and constant voltage functions; when the battery is charged, the two-way power supply converts alternating current to 14V Direct current, through the constant current board to realize the charging control and detection of the battery; when the battery is discharged, the process is opposite to the charging process. First, the battery voltage is raised to 15V through the constant current board, and then the two-way power supply converts the direct current into alternating current and feeds it directly. into the AC power distribution network of the factory, thus realizing the energy feedback of battery discharge electric energy.
Significant power saving effect: According to actual measurement, the power consumption of the device during charging is more than 40% lower than that of traditional devices, the comprehensive power saving rate is more than 60%, and the power consumption is more than 60%, saving a lot of costs for battery manufacturers.
