Levi, When I said "not done" I meant "not acceptable behaviour/outcome" If there is a bad handling of battery then there would be a permanent range loss that cannot be recovered. However you do mention in your later posts that the range loss was due to modifications to protect battery. Seems...

Losing 24 miles after mechanical update? That's like 10%! Not done. That's strange. Did you get the same battery pack back? Possible to compare serial numbers before and after? Another possibility is that Tesla service messed up. Most possibly, they didn't take care of your battery while...

SQLCPH testcase: 59KWh is the actual power that went in. Display on the left corner shows the DC power numbers (when display is in % battery) You can figure it out the efficiency as follows: Look at the charging screen anytime during mid-charging. 1. AC power = volts * ampere (right corner; this...

Okay. You started with 100% charge or 90% charge?

Let me correct myself. I went and checked the charging display when range setting is in battery %'s. SQLCPH: You are correct. In this setting, the charged amount shows in KW's not miles. Also that amount is the DC charge going into the battery (the charge is around 90% of AC Power). This is...

Okay. If you are charging at home from you wall/AC then on-borad charger is only 92%-93% efficient so your battery was actually charged by ~= 54*0.93 KWh.

SQLCPH: Question: When you say meter read 54KWPH. WHich meter are you referring to?

We are just going in straight line. How should it help?!

Interesting to note that 70D does 0-60 in 5.2 but 60 took 5.9 secs to get to 60mph. Surprised that the difference is so large.

I read somewhere that rated is 88% of ideal. In that case, if ideal is 267 then rated is 303 which matches with the display. In other words, rated could still be a fixed number. Lets see what else others are seeing

I am on 6.1: 2.2.179 I have this car from March 14. I might be mistaken but I think for a while rated number was around 288 Wh/mile then it started changing. I am not sure if it was due SW update or something else.

Oh. I never did notice that the 'line' corresponds to rated/ideal Wh/mile depending on rated or ideal is chosen for display. Thanks for pointing it out. Here are photos based on your suggestion: Photo1: in "rated" mode so the line represents rated Wh/mile. It just so happened that the average...

Okay. On my car rated range corresponds to 304 wh/mile which is very close to my average wh/mile for last several thousand miles. If I am not mistaken, my rated range number used to correspond to 28x wh/mile but then through the year my average miles went up and so did rated range number.

Okay. I know for my S60 Ideal range is calculated with 267 wh/mile. Is there a similar fixed number for rated range?

what I am saying is that between two users, User A and User B, who might have bought the car on the same day, live next to each other and have identical commute, and exact same mileage, still there could be 30% difference in rated range. This difference would entirely be due to different driving...

Just curious why everyone gives out rated number instead of ideal number. Rated number can vary +/-30% based on ones driving habits. Whereas absolute number would be more of a reference for comparison.

I understand that the capacity would differ based on discharge rate, temperature etc etc. However there has to be some reference condition (which could be not real world) such as 55mph, 25 deg C, elevation etc etc which Tesla uses to rate their batteries. The same rating conditions can be used...

Okay, here is picture of Energy plot just after it finished charging to 90%. This is before I start driving. (car is in range mode with AC turned off.) It shows that the battery capacity = 0.268 * 199 = 53.33 KWh So I have lost 0.67KWh in 90% charge. Converting that to full charge will be 59.26...

I am curious to know the actual battery capacity. I searched through the forums and I have seen the breakdown analysis with 7104 and 5040 cells, 3100 mAh per cell etc etc. with 85KWh being 86.6KWh. However it seemed more of continuing discussion and didn't see a firm answer. If I have missed it...

One has good moments and sometimes one has not so good moments. This is about a moment that falls in latter category. Encountered a blue debadged Tesla on 101S near Palo Alto. Rush hour yesterday morning. His lane was slowing down so made two fast lane changes in front of me and started...

True. One can treat (in a crude way) motor as an equivalent resistance ( say Rm) and let's say battery internal resistance is Rb. Then we have motor energy I^2*Rm and heat energy is I^2*Rb. Efficiency is then I^2*Rm/I^2(Rm+Rb) = Rm/(Rm+Rb) Note efficiency = Rm/(Rm+Rb) has no I (current)...

I think AlexKiritz's current chart explains the reason for higher consumption. If one steps on the "gas" then the motor is drawing a large current. Drawing large current (1c = 85/60 2c = 170/120 4c = 340/240 and so on) drops the voltage which is due to bringing a resistance (equivalent) in the...

Typically, lithium battery charge cycles are quoted as % of charge/discahrge per cycle. In other words, if only 50% charge/discharge cycle then it is considered .5 cycle. If 60% charge discharge then it is considered 0.6 cycle. Panasonic study just quotes data upto 3000 cycles for...

If you have an 85 and rarely use the last 60 miles, you are not dropping the battery below 20%. This means your battery will last significantly longer. 20% ! Really?! In any case, in my regular use, neither do I ever go below 30% on my battery either. Why is that everyone talks as if 85...

Taking the unused gas in the tank analogy a little further. It is Saturday morning so we can spend time doing "what if" scenarios. :smile: Consider a hypothetical buyer who drives locally and never does really need the extra range of an 85. Lets look at impact of buying 60 or 85 for that...

Taking on A7 gas tank analogy. The reason people don't pay premium for bigger gas tank is that there are gas stations almost around the block. Similarly, I am putting my money on future that around the time Tesla hits 200K+ cars there would be a third party supercharger every 50 miles. After...

Yes, I buy that argument. 60 is being kept alive just to show the capability of making a lower cost vehicle (as a path to E). Once model E shows up, they will have E60 and E85 ($50K onwards) and S85 and S??? ($80K onwards) and S60 will be dropped. I am sure this must have been mentioned earlier...

People buy 85 either for resale or "rainy day" trip/event. It is too early for resale. Same for rainy day. Let people drive for two years and they were will be a bunch who will say, oh, I never really need that range. There is another thread going on similar discussion and good points are being...

Well, there goes my conspiracy theory!

What I have read on suspension modification efforts done by several forum members is that newer cars have different sub-frame mounting, different lower control arms etc etc. Apparently, these modifications result in later models having more crisper drive with better roadfeel as compared to...

Yes I did go a bit over the top with my second and third point. However, my first point on rebalancing of demand for 60 still holds for me. In 2020 or so (4 years after X and 2 years after E), we will start seeing the effects inflection point of electric cars. You will find at least one gas...

Better resale value?! Hmm... let me put another argument for you. Currently it looks like Tesla sells 9 85's for every 60 sold. Most buyers don't need the range but Tesla is a new car company, all electric sedan a not fully proven concept. There is battery life-charge degradation anxiety...

aahaa... that explains it a bit more. This is a commute car for me. At least when I was buying this car, getting carpool lane stickers was an USP. (No hate mail please!) Thus there is a lot more right brain involved than left brain. If this is a fun car for you then go for what makes you happy...

Since I am not seeing any 60 owners jumping in, allow me. I am a 60 owner. When I was buying, I tried hard to justify 85. Even now occasionally, I do try, but still cannot come up with a good reasoning. :smile: See if you can relate to my rationale and glean something out of it. 1. Daily...
