Lowering charge amps for Supercharging

[Ketchups]

I haven't tried this but is it possible to lower the charging amp setting while supercharging?

 

[Stiction]

Don't think so.
Why would you want to do that?

 

[Ketchups]

Ahh Supercharging bypasses the obc, so I can't change the amp settings.

Plug it in and wait?

... the SC can pump 400V @ 300 Amps into your car.
Piddy little OBC would vaporize 8)

Lower it? I want them to double it!

SC told me it is all driven by the battery part of the computer sw. Sometimes mine sounds like it will explode. He dont worry, it was empty, you are getting full 400 volts DC into car.

Not adjustable. They want people in and out as quickly as possible.

You can try to plug in it half way. Never tried it on a Supercharger but on AC the car will charge at a lower rate if it's not fully plugged in.

In that case, it is detecting high resistance. I wouldn’t do that on purpose. It’s creating a heater.

That sounds dangerous!

The car notices the higher resistance and lowers the charge rate. There are also temperature sensors that would reduce the charge rate should it get too hot. But yes, it's never good to provoke a state that makes a safety feature kick in.

No. SC won't be your parking spot.

they should let you slow it down if the supercharger isn't busy.
-avoid the car permanently lowering the SC rate from too much use, save the limited # of full speed charges for when you need them.
-avoid the peak rates in states that have 2 tier pricing - it's double price above 60 kW.

It doesn't pass the "keep it simple" test. If people want a lower price, charge at home. Plus, the cost is 1/2 and the rate is 1/2. So not really saving anything. More importantly, never know if the charger will be busy in 20 minutes. Better to be full and out.

The urban Superchargers are kind of going in that directions. They are reduced power and are typically at malls where you spend more time. They are a hybrid between parking and charging. Tesla knows many people will use them on a regular basis so the reduced charge rate helps with battery longevity.

I totally agree. Better for the battery in the long run. I wonder if there is any movement on having that option.

Except for early 90kWh packs, there is no "limited # of full speed charges"

Not really. Even at 120kW, the charge rate is just not that fast relative to the battery's capacity. 1.4C @ 85kWh, less on larger packs. That's just not fast enough to worry about.

Plug into a paired charger where the other half is already in use.

If the other car is low in the taper (ie, low SOC/high charge rate), you will steal power from the other car doing that.
