8A current limit - does it work on L2 chargers?

For L2 it is 16amps (page 125 of the manual.....)

)

 

is the 8/12 option on the evse or the charger?

 

the charger

 

Someone else said yes, and that makes sense to me. Here's why.

I think it's always set to 16A and the EVSE that comes with the car has its own limit set at 12A, which the car follows. If you plugged in a 16A 12V EVSE, I suspect you'd get 16A.

If so, the limit is voltage independent which is why setting it to 8A would limit it for both source voltages.

 

The footnote #1 is for both options, so the answer is yes.

 

You will control max AMP in car setting..so it really doesn't matter what type of output is from L2 station....
For your question on battery life charging with lower AMP that is not necessary...Toyota have built measure where it goes down for last 40 minutes to slow charge and if necessary doing cell balance....I'm also engineer and i have this recorded with my tools...
Another thing to consider is battery is never charged more than 80-85 % of full charge....
In my work related experience testing limits of Lithium battery this current is definitely on longevity side that Toyota have done...16 amp are good

And on Prius Prime 8 amp setting will affect L2 charge same way...i have 2 Prius Prime

 

No you can't control current on chargepoint ......it is done by communication between car charger and chargepoint station..you have to remember that some have 8.5 kw limit and if someone is pulling on one side 6.6 kw you will get on another leg only 1.9 kw

Can you give us (layman language) links for reference to charging current vs. the life of a lithium ion battery?

 

It's true but irrelevant in this case because both charge rates are very slow (about 0.2C and 0.5C). Charge mode on the car appears to be around 1C, braking can probably be a lot more than that, and CHADEMO in Japan is well over 1C. Dropping the 0.2C 120V charge rate by a third will make no difference in battery longevity.

 

Unless there are ambient conditions - excessive heat or cold - and an owner still wants to charge during those conditions.
Of course those are extreme conditions with warnings concerning charging in the owners manual, not typical charge scenarios.
And charge mode will only charge up to 80% of primes charge limit which is around 60% of the packs actual limit
and since the engine is running the pack is or should be benefiting from heat or a/c conditioning while in charge mode.
As always ymmv
ps: When using the 8amp charge setting, the charge time can be ( was in both my experiments ) doubled what the charge time was using the Max setting.
So, like Lee Jay mentioned above both settings are just above trickle charge when compared to the rates other manufactures use.
I think they are smart to use these limits for a forced air cooled pack as the pack can still cook itself or get freezer burn under certain conditions and or bad settings.

 

Does anyone know if the Prius Prime would charge using 16 amps using a combination 120V/240V charger rated at 16 amp or if the Prius would just limit charging to 12amp? I would use it on a 120V, 20amp circuit.
I know standard charger at 120V uses 12 amps, 240 V chargers would use 16amps. Wondering if this might speed up charging without investment of 240V line?

Here is a link to a charger that can use 120V and 250V:

Thanks for your reply. Newbie to the forum.. couldn't find answer to this in threads.

 

It'll charge at up to 16A if the EVSE supports it, regardless of voltage. The EVSE that comes with the car only supports 12A because it only has 14AWG wire feeding it and because Toyota (rightly) assumes most people don't know the difference between at 15A and a 20A outlet.
