5V100A 8/16/32/48 channel lithium battery cell grading machine

The device adopts electric energy feedback technology, which has high energy-saving efficiency and low system heat generation, which can greatly reduce the heat emission, power consumption and use cost of the equipment;

• Three-phase balance technology (no neutral line) reduces the load on the power grid;

• Soft start function reduces the impact on the power grid;

• The equipment accuracy is better than 0.05%, the data recording time can reach 1000mS/time, and the stability is high;

• Single point independence, independent charging and discharging conditions can be set for each channel;

• It has complete input and output, software and hardware protection, reverse connection protection, power failure protection, and poor fixture contact protection;

• There is no impact current when the channel starts, and the constant current to constant voltage transitions seamlessly without any current surge;

• Multi-layer network integrated management, one computer can centrally control more than 1000 channels, and the large system supports remote monitoring;

• The DC internal resistance test process can be defined and set by itself, providing a high reliability basis for the battery cell grouping (customization is required);

• Channels can be freely connected in parallel as needed to achieve multiple uses of one machine;

• When the computer is abnormal, it supports offline operation at an appropriate time (need to be customized);

• Modular design concept, plug-in design of the box, easy to maintain;

• The output line adopts quick plug-in method for easy installation and maintenance;

• The battery end uses a gold-plated ejector clamp to press down to reduce heat and facilitate battery loading and unloading;

• The system control circuit adopts a digital circuit with a high-speed DSP digital signal processor with floating-point operation as the core

• Synchronous rectification technology is used to improve energy utilization efficiency and reduce hardware size

• Rich peripheral resources and high-speed digital computing processing capabilities enable it to meet the needs of data processing and system control

• The control variables to be detected are directly sent to the DSP through the I/O port for processing

• The hardware design of the system is simple and reliable;

• The modular design makes the system upgrade and maintenance more convenient

• The data is clear and comprehensive, real-time monitoring and uploading to the MES system (need to be customized);

• Data export method: Data can be exported to EXCEL and chart files, which can provide a variety of data analysis curves such as charge and discharge rate, charge and discharge curve, voltage, capacity, current-time characteristics, etc., and the curves can be imported into EXCEL.

• Curve type: X coordinate: total time, charge and discharge capacity, number of cycles, etc., can be set freely. Y coordinate: total voltage, current, capacity, monomer temperature, charge and discharge capacity, monomer voltage, etc., can be set freely.

• Software protection: power-off data protection, power-off suspension and connection, overvoltage and over-discharge protection, overcurrent and undercurrent protection, capacity protection, overtemperature protection, current fluctuation abnormal protection, charging voltage rise rate abnormal protection, discharge voltage drop rate abnormal protection.

• Hardware protection: battery reverse connection, overcurrent protection, overvoltage protection.

• Alarm function: The hardware has emergency cut-off switch, automatic shutdown after power failure, automatic load connection and disconnection, etc.

• Output line: four-wire connection mode, current line and voltage line are separated.

• Maintainability: modular structure, spare parts can be used for timely replacement and repair, free of charge during the warranty period.
