### 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.
