Resistance measurement

• Evaluation of the quality of spot-welded joints based on the contact resistance, for example, between the contact lug and the contact surface of the cell
• Connection via PROFINET, EtherCAT and EtherNet/IP supports flexible sequence control and measurement data acquisition

Task

Very high-quality of spot-welded contact lugs is elementary in industrial battery pack or module production. The adherence to important mechanical parameters and also electrical parameters such as extremely low contact resistances are extremely important for ensuring the performance of a battery pack or an entire module. With the aid of the RESISTOMAT^® 2311, precisely these spot welded connections are reliably recorded in the low capacitance range, evaluated within a very short time and transmitted to the control unit via PROFINET.
