2017 Ms P100d Max Charge Rate?

[Rastaman777]

I appologise if this has been asked before. I did search and couldn't find what I was looking for.

With all of the charging improvements being made lately do any of you think a 2017 MS P100D would be able to break the 150 Kwh charge rate? I don't know much about the physical component restrictions which I'm sure make a difference as well.

You need the raven refresh to break 150 plus a V3 SC ..I have seen 150 once in perfect conditions on my P100 ..mainly been getting 138-140

Ranger told me only very new cars, but very few chargers will let it happen. Also has to be a new Gen 3 charger I was told.
My antique will not accept it. I was in Florence SC, brand new chargers , guy next to me hit 130. I was on 100.
My car is having charging problems ever since v9 was installed.

Thanks guys, that's what I was looking for. I haven't seen much of an improvement either with the new battery pre conditioning feature either. Have you?

I have a June 2017 model s 100D and can charge at 140kw for the first 5 minutes or so under 30% (doesn’t matter for me if you start at 10% or 25%). Drops down to 115-120 or so until around 50% then tapers down as expected as it fills.

Mine tapered down to 61kW at about 60% charge on a 2017 P100D. That sound right? I attached a pic as well.

I have seen higher at that SOC but wouldnt worry to much as not sure your weather conditions at the time

I won’t be too worried. There are lots of factor determining charge rate. SOC is one, but I find temperature is the other major factor. In these hot humid days, I find that I peak faster but taper faster likely due to temp.

Supercharging rate really depends on temperature, of the ambient air but also your battery. My100D has charger at >100kw at 60% but also has tapered to 80kw at only 45% on a really hot day at the exact same station.

When you think you are charging slower than you expect, is the AC roaring like a jet engine trying to cool the battery down? How cold or hot is it outside?

My best on 11/2017 Model S is 130 for a several minutes at the lower charge level, it tapered into the 110' until I got over 50%.

No roaring........it was around mid 80's I'd say on this charge. Initial charging rate, followed by charging rate degradation.....

Your charge curve looks pretty good. You got 140kw from 29-42%, and maintained 110kw+ even at 50%. 70kw at 65% is a little low, but nothing unusual to me at least.

Well, that's what I thought........but poor Rastaman777 claims he normally gets about 61kW @ 60% when I was clearly getting 80kW even @ 61%. In fact, I didn't taper off to 60kW until 71%?

 

[Snowstorm]

I think temperatures has a lot to do with it. If we started at 140kw on a hot day, it is possible that the battery heated up too much by the time it is at 60% and tapers harder not due to SOC but due to temp.

Tesla’s have some if the longest lasting batteries and I think thermal management is a large part of it.

 

[Rastaman777]

Thanks haso I'llmuch everyone! I'll have to charge and take screenshots next time. Then we can compare rates.

 

[Rocky_H]

There was a pretty easy rule of thumb with the charge tapering curves that was nearly linear on the older 85kWh batteries where state of charge % + kW charge power = about 120-ish. It seems on the 100kWh packs that combined number is closer to about 150 for most of that bottom filling of the battery.

 

[Ludalicious]

As Bill showed above. I also see roughly 140 KW on my 2017 MS P100D. I also see my KW taper off after about 140-150 KW

 

[Rayme20]

Its definately possible

Just for the record when your car gets old, here is official word from tesla. I complained, got this reply.
