As I noted and gave links to in post 8 of this seemingly never-ending thread, this type of RV adapter will NOT work for an EV, you need a specific EV adapter as an RV adapter will give you 0 volts to the EVSE. The op needs to purchase an EV adapter or the OEM and be done with itTechnoRV 110-Volt to 50-Amp RV Adapter

As pointed out in post 8, RV adapters are cheaper due to larger sales but won't work.
