Anyone know what these dots under PRND mean?

[chrishawn]

I assume it has something to do with regenerative braking but local Tesla service didn’t know either.

That means your max regen ability is reduced. Potentially due to high battery temps, high state of charge (looks to be that in this case), or some other variable with the battery. They'll go away once your SoC starts to drop.

I'm use to our graph and colored dashes on our MS so this was helpful to know. Thanks for asking the question and for the answer.

 

[creativeguy]

KFORE is right. I charged to 100% for a trip and had no regeneration (it coasted), and showed even more dots than that until I ran down the battery a bit. Then the regeneration returned and the dots changed to the line.

 

[RayK]

Yes.

Related note: When I rented a 3 back in January I saw warning message the morning after the car was delivered to me. It said that regen had an issue. I thought I had broken the car. Only after I did some reading here did I realize that cold weather affects the battery charging.

Same. I even called it out as a bug with the firmware in my original review post for the car. It was still under 30F back then.

OP is smart to realize what it is; but "local Tesla service didn’t know" is a real forehead-slapper.

Employees should RTFM!

Yeah, page 43 https://www.tesla.com/content/dam/tesla/Ownership/Own/Model 3 Owners Manual.pdf

On the energy bar, black (or white in night brightness) represents energy being used during acceleration and green indicates energy being gained through regenerative braking. A dashed line appears on the energy bar when power available for acceleration or power that can be gained by regenerative braking is being limited. Model 3 limits power for many reasons. Here are just a few examples:

• Acceleration may be limited when the Battery is reaching a low state of charge or if the powertrain is hot. • Both acceleration and regenerative braking may be limited when the ambient temperature is either very warm or cool.

• Regenerative braking may be limited when the Battery is fully charged.

I see you're located in MN. Wait until the winter. Those dotted lines are going to look like this:

Interesting. I only charge to 80% and still get these dots on my short commute. The conditions don’t seem to match any listed in the reasons why the dots would appear. Maybe the battery is just cold even though the temps are in the 50s

For me it seems to need to be above 70 to have no dots when starting out. Now with the temp being in the 40s a couple day I don't even get rid of all the dots before I finish my short commute.

 

[boiler81]

Yeah, Mine showed some dots on the "regen" end when the temps dropped below 50 deg. for the first time. I however did get a message on start up that regen was limited.

 

[JeffK]

I've got dots on the regen for the first ten min of every drive. Outside temps are in the 70s, battery is not full.

Yes to even with "temps in the 50s". We noticed this in our Model S too first year we were driving it, although it appears in yellow there so more noticeable on the screen. Surprised us as 50s didn't seem all that cold to us. Got warmer outside and not there.

 

[Msjulie]

I think the 'warning' message was replaced with just dots, I see dots on my car's display and the temp is low 50s. Earlier in the year I got the (more scary) warning about reduced regen.

 

[ChrisH]

Okay so sounds like normal operation at this point. Good to know.

 

[ChrisH]

Hmmm. I was in the car for 50 minutes after work today. It was 55 degrees out. The dots never went away.

 

[Darthbenji]

I get them too. I’ve found that charging for 30-40 minutes before I leave on a cool morning (warming the battery) but not to more than 80% or so let’s me leave with full regen capabilities.
