+### 2023-04-16 EvseMode brings the Ioniq to close the contactors
+With simulated rising EVSEPresentVoltage in the PreChargeResponse, the Ioniq indeed closes the contactors, without
+the need to feed physical voltage to the CCS DC inlet pins. This is surprising, because - at least for ISO -
+the specification says that a physical measurement shall be done. The Ioniq does not, it just relys on the
+reported voltage on the charger. After closing the contacts, there is the accu voltage on the CCS. Not yet
+tested, whether it is possible to draw some current out of the vehicle.
