Just an FYI, I am an electrician and an Electrical Engineer so I know a little bit more than most when it comes to chargers and HPWC units. I see posts of people connecting dryer cords and range cords to the HPWC units. All electric devices including EV chargers and the HPWC units are UL listed. This means that they are listed by Underwriters Laboratory to be connected exactly as designed. You have to be cautious of this because installing a cord on a device that is UL listed to be hardwired will invalidate the UL listing on the device. This voids all warranties and can give your insurance company the right to deny the claim if your house catches on fire. All UL listed devices are required to be installed as designed.
The other more technical reason not to do this is that a dryer cord is UL listed and rated for 30 amps and a range cord is UL listed and rated for 50 amps but a dryer usually only has a continuous load of 20 amps and a range usually only draws about 40 amps continuously with all the burners and oven on full. Heating elements in dryers and stoves cycle on and off so the load is never continuous. Electric vehicles chargers are full on until the vehicle is charged.
Using either a dryer cord or a range cord on an HPWC is a surefire way to set the house on fire. Neither cord is designed for the loads presented while charging a vehicle.
