Which public plugs work for 2020 Prime

Any available 120VAC outlet using the EVSE that comes with the car. Motels, campgrounds, etc. frequently have these where you can use them.

 

All J-1772 Plugs will charge, Level 2 plugs can charge as fast as 2 hours, Level 1 in 5.5 hours. J-1772 is on your cable Toyota supplied. No matter how many Amps the EVSE can provide, the Prime only draws 16 Amps

CHAdeMO is a DC system, both the plugs and the voltage are incompatible.

NEMA 14-50 is often used in RV/state parks, you can buy or build an adapter to the 5-15 on your existing cable to make it charge in 2.5 hours. (this adapter is non standard as it makes a 5-15 receptacle at 240 volts)

CCS is a tossup, there are two style connectors, one allows J-1772, one does not. Assume it does not work in the US, and does in Europe.

Choose J-1772 (and NEMA 14-50 if you bought/made that adapter. Often stuck in RV parks)

It took me a long time to figure this out but perhaps this will be of help.

I live near free public charging stations in Santa Monica. Every time I would take my empty battery Prime to get charged, it would take 4hrs and 50 mins to fully charge. I then realize I had the wrong setting on my car.

The manual nor this community tell you this BUT if your car takes a long time to charge on a public charging station, please go to the car settings and change the charge settings from 8A to MAX!

You can now charge at Level 2!

 

I’ve seen that setting mentioned here before.

And I use it every day to charge at work(since I’m there for more than 8 hours, I 8A charge).

 

@PrimerPrius, yes, it's been mentioned here a lot. But it's not bad to repeat it.

As for the manual, it's on page 123 in mine:

 

I thought the default is 12A on 120V, and 16A on 240V. I never checked or changed the setting on mine, but it dose complete charging by OEM EVSE at 120V in less than 6 hours.

 

That's roughly what my meters read.

 

YES! But it doesn’t do a good job explaining:
“Level 1 / 120V (Slow charging) select 8A”

“Level 2 / 240V (fast charging) select “MAX”

It’s confusing and unclear.

 

I can't find your quotes in my manual. Where did you find them? My manual doesn't say anything about charging voltage in the section about selecting charging current.; just charging current. Heat is a function of current, not voltage. The ability to reduce charging current is there solely for those situations where there are other loads on the same circuit breaker and they cause the breaker to trip when you plug in the car.

It's perfectly clear. Use the lower amperage if the breaker trips when using max amperage. Done. That's it. Voltage is no more of a factor in this than the color of your shoes.
