1. Overview
Should the grid-fed energy-saving battery testing equipment is an exclusive product launched in China after years of research and development by Semco Infratech Pvt. Ltd. PWM high frequency power feedback technology. The latest generation of energy-saving battery testing equipment is widely used in the chemical composition and volumetric testing of lithium-ion batteries and nickel-metal hydride and nickel-cadmium batteries. Should Product stability, energy saving, precision and quality have been welcomed and praised by many battery industries. The overall technology is currently at the leading domestic level and is leading the technological revolution of the battery industry.
2. The structure and appearance of the equipment
The structure of this equipment is mainly composed of the following parts:
- 1 CPU board, the whole cabinet is sent and controlled uniformly.
- There are 24 four-channel constant-current plates, evenly arranged in four doors.
- There are 4 bidirectional inverter power supplies, each for 6 constant current boards.
- 2 keyboard boards, front and back double-sided operation.
- Common twenty four Block pallet, pallet depth 25cm, with epoxy board insulation, each pallet 4 channel, alligator clip 60cm lead.
3. System structure and working principle
System composition
- Lithium battery into capacity equipment (1~10tower).
- A computer with a USB interface (bring your own).
- A USB to 485 interface converter and communication line.
- A set of SEMCO product software.
System principle
The equipment is connected and controlled by a computer to send instructions and collect data; the keyboard can manually operate the equipment to display parameters and status; the constant current board is ordered by CPU, has constant current and constant voltage functions; when the battery is charged, the bidirectional power supply converts the alternating current into 12V direct current, and the constant current board realizes the charging control and detection of the battery; when the battery is discharged, the process is opposite to the charging process, and the constant current The board increases the battery voltage to 12V, and then converts the direct current into alternating current through the bidirectional power supply and directly feeds it into the factory’s alternating current distribution network, thereby realizing the energy feedback of the battery discharge electric energy.
Significant power saving effect:
After testing, Should 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%, which saves a lot of costs for battery manufacturers.
