Our most used adapters when towing with an Electric Vehicle.
Hi folks. I had to take a pic for the Facebook EV towing group so I thought I would post it on the forums as well although I don't think there are many on this forum towing with an EV. This is more specifically aimed at those EV’s using the Tesla mobile charge cable but since any EV can use a tesla mobile cable (with a J1772 adapter) I’ll direct this at all EV’s. I know the Ford Lightning dudes are getting the Tesla mcu for their travel kits. And remember, ask permission, follow the rules and follow the one thing at a time plugged in etiquette.
Anyway. If you are just starting your EV tow vehicle journey wether that be with a Rivian, a Lightning or a Tesla these are the adaptors we have used most often over the last 12000 kilometres of towing with an EV using our Tesla EVSE seen in the picture. Obviously this has to do with charging from an AC source like houses, campgrounds etc. DC fast charging is another topic.
So From left to right.
14-50 Good for max 32 amps at 240 volts on a 50 amp pedestal.
5-15. Good for 12 amps at 120 volts on a standard 15 amp receptacle.
5-20. Good for 16 amps at 120 volts on a standard 20 receptacle (getting really common on pedestals and it seems to be getting common in driveways as well.
TT30. Good enough for 24 amps at 120 volt on a standard 30 amp RV pedestal.
Keep in mind that if the line voltage sags the EVSE (charge cable) will detect this and lower the charge by either 25 or 50 percent depending how low it is.
By far and away the most useful was the TT30 as 50 amp receptacles are rare up here in the places we camp.
And of course the best way is still at a DC fast charger.
Hope this is useful for newbies towing with an EV. There are other dongle adaptors available if you have access to welder plugs etc but these were our most commonly used.
