Investigation of Galvanic High Current Contacts

Outset
Due to the high currents transmitted from charging stations to vehicles and the physically inevitable contact resistance, there is considerable danger of a massive voltage drop at the contact point. This difference in voltagesleads to a loss of useful energy, which is converted to heat at the contact point. This, in turn, may lead to an unwanted heat build-up in the components, causing thermal and mechanical wear or even a breakdown of the overall system.
