3.Technical parameters

Fixture

Each fixture is divided into 17 layers of heating plates, and there are heat insulation measures between the heating plates and the fixtures. Each layer of heating plate is equipped with a temperature probe. PLC can inspect the temperature probe of each layer of heating plate and display the temperature detection value on the touch screen.

PLC control

This equipment implements PLC control: the heating target temperature can be set, and the equipment controls the heating plate according to the target temperature, and protects and alarms in time when the heating plate is over-temperature.

Working temperature

Room temperature90℃, temperature control accuracy of each layer of heating plate is ±3℃.

PLC controller accuracy

PLC can realize 5-stage pressurization control on the fixture, and the pressure control accuracy can reach ±30kg.

Testing method

The four-wire method is used to measure the current and voltage of the battery cell. The circuit connection between the fixture and the device is realized by a special PCB. The electrode plate is installed on the device. The battery is pressed by the upper and lower plates to achieve a fast and reliable connection between the device and the fixture circuit.

Safety

The doors and observation windows around the equipment have heat insulation measures. The equipment is equipped with security access control to ensure that the equipment is safer and more reliable.

Setting range of charging and discharging voltage

1.Setting range of charging voltage: 0mV5000mV (resolution 1mV);

2.Setting range of discharge voltage: 2000mV5000mV (resolution 1mV).

Setting range of charging and discharging current

0mA5000mA (resolution 1mA)

Measurement control accuracy

1.Voltage measurement control accuracy: ±(0.1%FS+0.1%RD);

2.Current measurement control accuracy: ±(0.1%FS+0.1%RD);

3.Time measurement control accuracy: ±(0.1%FS+0.1%RD).

End conditions of charge and discharge

1.Constant current charging (CC): the end conditions are voltage, time and capacity;

2.Constant current and constant voltage charging (CC-CV): the end conditions are current, time and capacity;

3.Discharge method: The end condition of constant current discharge (DC) is voltage, time or capacity.

The main functions of the software

1.Control the end conditions of the process according to time, voltage, current and other parameters;

2.Calculate the charging capacity parameters of the formed battery;

3.Editing and management functions of charging and discharging process:

3.1 Up to 32 step parameters can be set;

3.2 Can set up to 256 cycles;

3.3 Each step can be selected by attributes such as constant current charging, constant current constant voltage charging, shelving, constant current discharging, and cycling;
