A method of checking a ground contact unit of an electric charging infrastructure. The ground contact unit has a plate-shaped base body and a plurality of contacts arranged on a charging surface of the base body, against which a vehicle contact unit can rest. The method includes performing a contacting check to determine whether at least a subset of the contacts is contacted, performing a protective conductor check to ascertain a contact quality by passing a test current across at least one of the contacts, and performing continuous touch protection monitoring by continuously monitoring switching positions of the contact switches assigned to power contacts that are not part of the subset of the contacted contacts, and/or by continuously monitoring an existing contacting of at least one contact that is part of the subset of the contacted contacts and/or by performing a voltage measurement on at least one of the contacts.
