I am interested in potentially buying a Tesla Roadster but want to make sure that I understand the various charging options:
Roadster to normal 120V outlet
Roadster to NEMA 240V outlet
Roadster to J1772 via CAN-JR
Roadster to Tesla Desination Charger via CAN-SR
Roadster w. JdeMo to Chademo (20% to 80% of battery usable capacity in ~45-55 minutes)
Is that correct?
How quickly do these various solutions charge the battery?
Good list, but I would note that the "NEMA 240v" solution actually can cover just about any wall plug, via the adapters that are designed for the Universal Mobile Connector. The 240V 14-50 "RV" outlet is just one of the choices, though probably the most common. Also covered are the clothes dryer outlets (10-30 and 14-30), and some other less common ones.
A full charge on a regular 120v outlet is something like 30 hours; not recommended unless your expected driving is very limited, or you have no other alternative. It's the least efficient of the set, besides the most time consuming. Most J1772 chargers that you find in the wild are 30 amps at either 208 or 240 volts, and will give you about 20 miles of range per hour of charge. The Tesla Destination chargers are often 40 amps, but can be up to the full 70 amps if you're lucky. 70 amps will give you a full charge in less than 4 hours, but in all of these, you will likely never need to go from empty to full, so scale things accordingly. An EV driver is most happy if its car is always plugged in whenever its not being used, unlike a gas car where you only fuel it when you have to.
