| 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 temperature~90ºC, temperature control accuracy of each layer of heating plate is ±3ºC. |
| 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. |
