5V 20A 192 Channel Grading Machine With Energy Feedback for Prismatic Cell



1.Overview

The energy feedback type square battery charge and discharge test machine is used to test the capacity, cycle life, internal resistance, energy density, temperature characteristics and other parameters of the battery, so as to evaluate the performance and reliability of the battery. This test cabinet adopts the energy-saving technology to feed the energy released by the battery back to the power grid, so as to realize the energy-saving, efficient and reliable test process. It is widely used in lithium-ion batteries and nickel-metal hydride batteries formation and capacity testing of nickel-cadmium batteries. The product's stability, energy saving, precision and quality have been welcomed and praised by many battery industries. 


2.The Structure And Appearance Of The Equipment
The structure of this equipment is mainly composed of the following parts:
1)One CPU board, the whole cabinet sends and controls uniformly.
2)There are 32 four-channel constant current plates, arranged evenly in four doors.
3 bidirectional inverter power supplies, each for 8 constant current boards.
4)Two keyboard boards, front and rear double-sided operation.

5)A total of 16 pallets, the depth of the pallet is 22cm, the epoxy board is attached for insulation, each pallet has 8 channels, and the downward pressure clamp.


3.System Structure And Working Principle
System composition
1)Lithium battery pack equipment (1-10 units).
2)A computer with USB interface (provided by yourself).
A USB to 485 interface converter and communication line.

A set of TMAX product software.


4.Working Principle
The equipment is connected and controlled by a computer, sending instructions and collecting data, etc.; the keyboard can manually operate the equipment, displaying parameters and status; the constant current board is ordered by the CPU, and has constant current and constant voltage functions; when the battery is charged, the bidirectional power supply converts AC power to 12V Direct current, through the constant currentboard to realize the charging control and detection of the battery; when the battery is discharged, the process is opposite to charging, the battery voltage is first raised to 12V through the constant current board, and then the direct current is converted into alternating current through the bidirectional power supply. Into the AC power distribution network of the factory, thus realizing the energy feedback of the discharged electric energy of the battery.

Significant power-saving effect: According to actual measurement, the power consumption of the device during charging is reduced by more than 40% compared with 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 cost for battery manufacturers.
