Contact resistance measurement in EV bolted joints, language: EN, in-house / Monitor EV bolted joints resistance (IE)

E-vehicless have extremely powerful drive batteries and have a high-Voltage section and a separate 12-Volt battery. One vehicle, two batteries and two voltages - that requires special attention when bolting the vehicles. It's no longer just about the mechanical fastening of vehicle components, many screw connections are deliberately designed to be live, have potential, others must be potential-free.
