Just moved - now my commute is MUCH MORE trafficky - what SHOULD this do to my range?

[bluegrassvroom]

ok, my old 'commute' was +/- 5 miles in 9-10 minutes
New one is 3.3 miles in 14 minutes

I'm fairly certain i was getting 170 miles IF i drove it 100% - but i tried the whole 20-80% thing, even though i only charged L2 at home

for those with similar driving (downtown, through/near campus with umpteen crosswalks, streetlights galore) - what do you see with your range?

My Porsche Connect has expired so I'm doing the numbers manually and it's absolutely ABYSMAL.

as an aside - i JUST got a new battery - and thought that everything would improve - but i'm seeing less than HALF what i thought i would. I figured before i complained to Porsche - i should ask you guys what i should expect in terms of range and maybe even the dash display of - CONSUM. - ___kWh / 100mi

It's been cool, borderline cold, but NOT ridiculously freezing where i think it'd affect the mileage/range

i always thought stop/go traffic was BETTER for EV's with the extra regen capacity. But with the timing of my move and new battery - i have no idea if it's my commute killing my efficiency/range or if it's a faulty battery....

I do not see anything unusual with what you are experiencing.
J1.1 generation for your 2021 4S efficiency in cold temperatures combined with highway speeds is not great and just because you have a new battery may have a short term effect as HV battery loses 10% of health during the first 10k miles and then another 5% during the next 10k miles. Also, do you know if you got a refurb J1.1 battery that can still go bad on a cell by cell, or you got the J1.2 battery with new chemistry that would not give you more range but would be a better deal long term.

The best advice I can give is for you to get an OBD reader and scan for Battery Health and Cell Health using CarScanner app so we can compare to what we see across other owners.

Bottom line, for me I am not complaining about range as I am fully aware of what to expect. I get close to 270 miles under ideal conditions and as soon as it got cold things got bad quickly as garage is cold, highway driving is range killer and chills the battery even more with cold airflow, then car stands in a cold parking lot.

You've got a lot of factors working in different directions. Your average speed on the new commute is lower, so less loss due to wind resistance = more range. You are doing more stopping and going, so even though we have regen to regain much of that loss (instead of losing it all as heat in braking), it's less efficient than steady pace. Cold weather reduces range. AND - on top of all this, the range displayed is only a conservative estimate based on a formula that takes in to account things like ambient temperature, recent driving habits, terrain/elevation change on the current route, driving mode (sport vs normal) etc. A lower estimate generally doesn't reflect anything about the condition of your car or battery - it's just the result of applying the formula. That being said, if your daily commute is 3.3 miles each way and you can charge at home, range isn't much of a practical issue until you embark on a road trip, and at that point the range estimates you're getting on your daily commute are irrelevant.

In 3.3 Miles, how much braking is done by regen, and how much is done by the friction brakes? The first X amount of braking is done with the friction brakes as far as I know.

I do quite a few short journeys and often quite a lot is stop/start.
That is really poor consumption as everything is heating up (including battery).

If I go on a longer journey (on more major roads, less stop/start) the consumption steadily improves as I drive.
Unless its really wet, or if doing 'high' speed.

My thinking is its similar to ICE......
Short journeys from cold are poor, but longer journeys in mid range speed are best.
But road and weather conditions have more impact than ICE.

Slow speed, short journeys and low ambient aren't ideal for EVs - similar to an equivalent ICE where consumption is higher also.

Recuperation kicks in around 1 mile of travel but will be of no material value thereafter given the lack of speed and braking force.

In winter on a 4 mile commute I'd see 1.8 mi / kwh with my GTS ST and in summer 2.3. Max on a long journey I'd peak at 2.7.

Short trips are a killer. Unlike Teslas which attempt to recover the heat from the cabin once you park, etc. with the Taycan every trip has some energy overhead to heat up the cabin and the battery. Furthermore, Porsche hides parking losses in the first trip after parking. IMO it's your biggest reason for poor efficiency. Take a 60-120mile trip, see the efficiency is. City traffic will be better than 70mph cruising too. Last but no least, how you drive matters. I always smile how my wife's car consumption numbers go down when I drive it, vs. when she drives it (it's an eTron, we charge it to 80%, when she drives the estimated range is over 200 miles at 80%, when I take it for a spin, it drops to numbers like 189miles).

The heating of both cabin and drivetrain takes quite a bit of energy. If you have a shorter drive it have a much bigger impact on the average consumption.

You can try and se a departure timer to preheat the car. That will take care of getting everything up to temp and you will then be able to see a bit clearer how the actual drive is doing with regards to consumption.

True, it will charge the battery up to make up for lost charge while parked too (otherwise that just gets added to first trip consumption). Not only that, if plugged-in, the departure timer also uses shore power for pre-heating, rather than from the battery.

Yup. I have used it from time to time if I need to stretch range etc. Usually I don't bother with it as I charge the car over night every day and that leaves me with plenty charge for my 110km commute.

What confuses me is that if I know I'm going somewhere in 30 minutes, if I just enable preheat in the app, the car will draw from the battery until the battery drops 1% under target SoC (at which point the car starts charging, so presumably the HVAC runs from shore power). If I use a timer instead, the car will preheat from shore power instead, avoiding unnecessarily cycling the battery. The only explanation I can come up with is that different software team implemented departure timers vs. instant pre-heat, and they never talked to each other.

Hello, I need to know how to program my vehicle to charge from 00:00 to 08:00 in the early morning up to a maximum of 80% battery. I have tried but I don't know how to do it.

I have Taycan 2022

Thanks!

i always thought it was the opposite - the first x% of braking was regen until you jammed on the brakes and the mechanical ones applied....?

that sad, the first few uses brake uses in a Taycan in a journey are mechanical i thought to clear the dust and keep the mechanical brakes in operating shape

 

[bluegrassvroom]

ok - all that makes sense - thank you

so if i MAINLY did short trips in cool weather (40-50°f / 4.5-10° C) then you'd expect this?

33412 - 33315 = 97 miles - i took my charge from 100% to 34% - so i used 66% of the charge. 97 miles / 0.66 = 147 miles (for the whole 'tank')

I guess it's not as bad as i was thinking - it was much worse earlier in the week until i took a 20-30 mile trip one day - that must have brought the average up like ya'll said

ok - i won't botch and complain about the new battery's effect - unless i take a longer trip and see it's way down from where it used to be

for my short trips, the consumption - kWh/ 100 miles is sometimes 100-150 (putting me at 66-100 miles on a full charge)

thanks for the facts, opinions, and logic

As a side note, if you just got a new battery, it'll take 500 miles or so for it to learn your current driving habits, which will make the range guesstimation more accurate.
