I'm looking to move from a Mazda3 to a TM3 or a TMS, and fuel cost is part of the equation. Using pretty pessimistic numbers, though.

Comparing mpg to l/100km, mpg feels less intuitive when it comes to comparing actual fuel use and potential savings.

Make a rule that if you charge before lunch you can't have the charger after lunch, and don't worry about it. Thats still a pretty good charge for 6 employees a day. How many of you employees have EVs? 3 chargers isn't going to be enough long term, regardless of how you ration them.

The whole 'free charging' concept was why my company no longer has marked EV spaces near outlets. Too many bubbas complained about employees getting 'free gas' when they had to pay to fill up their F350s. I offered to pay $25/month for what I estimated my Volt was consuming while plugged in at work, but there were concerns that would be seen as paying for parking closer to the building. Which is also why they didn't install charging stations after I practically submitted all of the needed documentation for them to get free charging stations from the state.

This is a management problem.

Also re low/high power outlets: Type 1 charging with normal outlets isn't recommended for permanent charging use, at least not here in europe...

Type 2 with load balancing means that you have the opportunity to charge up quickly if the power is available, but everyone gets their fair share regardless of how many users you have, even on limited power.

I've noticed the AP performance has increased significantly from when I got it on my 3 sometime in September until today (keeps in the center of the lane of the highway even better and no longer encroaches on double lines in twisty roads where it use to). It also freaks out less frequently when seeing shadows of overpasses / overhead highway signs.

Completely unrelated to the first point, a friend of mine wants to buy an EV and was looking at a 2018 leaf. I know it still doesn't have the liquid cooling battery management system but has Nissan managed to remedy the battery degradation issues associated with the lack of thermal management or is still an unknown?

The Leaf is loving useless in its current iteration though. Thing can't fast charge if it's too hot, and there's no active cooling.

I spent new years driving a brand new S75D from Tromsø to Drammen in a winter storm. Apart from some seriously dicey road conditions and a ferry that got delayed, it was fine. The supercharger stops were well timed for breaks I needed anyway, especially in the weather I was driving in. I can imagine it's a bit more boring during the summer.

The road conditions were so bad that the average power consumption was around 300 Wh/km for a while, and I chose to charge some (10%) at a 22kW charger while I took a break, to be sure that I had enough battery to reach the next supercharger. Effectively this wasn't an issue as I had over 20% when I reached Storjord supercharger, but better safe than sorry when you're out driving in the middle of loving nowhere during a storm.

I thought they had better traction control than that? Surely the combination of electric motors and ABS gives you near-instant control over wheelspin.

There's only so much the computer can do when faced with a retarded driver.

In general, traction control in the Tesla is pretty goddamn good, but it can easily get you into trouble too.

It's a Model 3 issue since it doesn't have a resistance heater to warm up the battery pack, instead the drive motor heats it up, and it's not so good in the super cold. I don't think Norwegians will like the Model 3 as much.

~270 to ~95 miles range in -15C still sounds like bullshit. But we'll see, TM3's are due to be delivered in a few weeks and with some luck we'll have a proper cold spell before spring to experience how poo poo they really are.

Yes, you get range reduction during winter, it's both due to temperatures affecting the battery (when it's below freezing), and colder temperatures equalling higher air resistance due to air density increasing by an appreciable amount when temperatures drop. But we're talking 25-30% loss in range, not 60%.

I averaged 202 Wh/km driving from Tromsø to Oslo around new years eve in a brand new Model S 75D. That was during a winter storm. Worst areas I was pushing 300 Wh/km (1-2 inches of slush/ice/snow), and my best average between charges was like 160 Wh/km (bare roads, doing 45-55mph in traffic).


Trip B is from Trondheim to Oslo (ca).

I've experienced parking brakes sticking a bit after parking in a heated garage overnight, and windows sticking a bit in -12C (as in you can hear the window unstick from the rubber gasket), but that's it. Doorhandles have been perfectly fine so far.

Edit number gently caress knows: We have a metric asstonne of Nissan Leafs over here, and they are truly poo poo during winter, even with a heat pump. 50% range loss is typical. I guess that's what no battery heat management gets you, heh.

Well, I live in Norway and I am currently sick and tired of my 24kWh Leaf's severely reduced winter range (mostly because it takes so much of the pack to warm the car up that even short trips take 10+% of the available energy). I'm strongly considering a Tesla model 3 because it's more battery capacity for the money than other options, and unlike the e-Niro and Kona electric if I order it now I'll get it before next winter. The supercharger network is a nice bonus. This is the first I've heard of such a reduction in range from the cold with the model 3.

Do you park in a garage? or have a charging point at home?

There's a lot of discussion on elbilforum.no as well, and that kind of range loss has not come up once, and if you're on there you'll know that there's a few trolls there that like to point out poo poo like that whenever they get the chance (like on every forum, I guess :haw: ).

Any reason why you haven't considered buying a used Model S instead? They've got unlimited supercharging, you know.

Unlimited supercharging doesn't make that much of a difference. It's 1.70 NOK (20c US) per kWh here, and the Model 3 is disgustingly efficient to boot.

Cocoa Crispies posted:

Not just range suffers on a cold Model either. Regen & acceleration are also reduced with a cold battery. Coasting without braking doesn't slow you down as much, and it won't accelerate as hard if you mash the party pedal either.

Rode with a friend who's a big time bazinga (like, bought a Model S, bought a Model 3, met Elon, traded in the S for another 3) and I got to witness the door handle, window, regeneration, and acceleration issues firsthand last week.

This happens to ALL EV's, though, not just the Model 3. The S and X doesn't have a lot of regen either on a cold battery, but it heats up enough to have decent regen after about 30-45 minutes of driving, even in the cold, and the pack retains heat fairly well once warmed up.
In -10C I need to drive about an hour to get full speed at a supercharger (93kW at 40% SoC in a 75D), while full regen is available sooner.
It further highlights the need to leave for a longer trip with a mostly full battery if possible, or that first supercharging stop will take a while.

Currently, I don't. My condo will be building an underground parking garage over the next couple of years, so I will in the not too distant future. If they are not complete idiots (condo management is frequently idiotic) they will also make the installation of charge points in this parking garage possible for residents.

It's mandated by law that the condo management can't hinder installation of charge points unless there are very specific circumstances, so that shouldn't be a huge problem.

When building a new parking garage, installing the necessary electrical infrastructure for charging is a minor cost-driving factor. Even using ZapChargers that are fairly expensive we're talking around $2700 / 25000 NOK per parking spot to retrofit an existing garage, so a new build will/should be somewhat cheaper. You absolutely do not want to use "dumb" charging points though, as peak power tariffs are coming and the penalties for exceeding them are pretty stiff. Source: I work in EE/automation and some of my colleagues work directly with EV charging solutions.

E: I also charge at work right now, and since my condo management is sorta retarded, I've asked for pricing for a 32A 230V 1phase industrial outlet. I'm not going to blow $1500 on a charge point if they're going to mandate Zapchargers next year so I have to pay twice. The 32A CEE outlet will cost like $600 installed, and I can live with using the CEE adapter and Tesla UMC at home for a while.
That being said, I only commute 50km per day, so if I get 7+ hours of charging at work on 13A, I'm set. I also live 2km from a large Supercharger (16 spots) that is seldom busy, so I stop by there when I come back from trips, and 1-2 times a week when I have to buy groceries anyways.

Ugh, this is why you always charge before parking at the end of a trip (if it's cold).

You can pull a TeslaBjørn though, if you have enough battery left. Find an open stretch of road and do hard acceleration and regen pulls for a few minutes to get some heat into the pack.

The S/X has a 6kW block heater for the coolant loops, while the 3 does not, so that significantly hurts it in the cold, thus my suggestion above.
Typical supercharge speed in an S/X with cold battery is like this: <0C = 0kW, all power goes to heating, 0-12C = <30kW, 12-24C = 30-60kW, >24C = sliding scale 60 to 90/110 kW as you hit 30-40C in the battery pack. Very rough numbers going off memory here, so it's probably not 100% accurate.

I'm looking forward to the reports on the Norwegian EV forums when people start getting their cars in a few weeks. I wouldn't be surprised if Tesla adds a heater in the next revision of their battery packs if they get enough complaints.

Nfcknblvbl posted:

Whenever my battery's cold before I show up to a supercharger, I drive it like I stole it for about 15 min. The on-board heater will never get the battery up to the temp it needs to be so accelerating hard heats it up quick.

:same:

if I know I have to supercharge on my way home from work (25 minute drive) in the cold, I do hard accel/regen pulls until I get full regen, and then some more to be sure the battery pack is warm enough.

I got my S75D a month ago, so my experience with an EV so far has all been from winter driving.

Bjørn Nyland has published a review and a winter range test.

Different OEMs tune accelerator pedals differently. Different modes in the car remap it (so in eco you get much less acceleration at 10% throttle than in sport mode, for example) and then OEMs also tune the pedal differently depending on the market. For instance, in the US and Japan, Mazda makes their throttle pedal quite linear and with as little lag as possible between input and power delivery. But in Germany, customers like the sensation of a short (0.25 second) lag between pressing the pedal and anything happening, so in Germany Mazda sets up the cars to do that.

I've had that weird throttle thing on some cars and its really loving annoying. My Mazdas have never been like that, I've had a couple of 626's (one '87 2.0, one '88 2.0i 16v), a couple of 323's, a Mazda 6 and currently a 2015 Mazda3 and a 1999 MX5 10AE 1.8, so I have some experience with them.

The expectation is that the model 3 will charge at 150+ kW. Its currently limited by the BMS. Supercharger v3 is expected to push 150-180kW according to some sources.

Wibla
Feb 16, 2011

I'm phone posting like a bad and forgot a minor but important detail. My point about the BMS limiting charge speed was that tesla doesn't have enough data on >120kW charging, so it's limited in software until they do.

At least that's my theory, and it seems to make sense. Charging at less than 1.5C can hardly be called fast. The older 75 packs are even more gimped.

I'm really looking forward to the CCS adapter, so I can semi-fastcharge (>70kW?) my model S in Oslo without having to find the nearest Supercharger.

One detail with the upcoming supercharger v3 upgrade is that it'll probably mean faster overall charging, especially for the second car that connects to a charger pair. As-is, the chargers seem to max at 125-140kW total per pair, limiting the first car some and dumping the second car at 30kW charge speed until the first car starts tapering. More powerful chargers will decrease charge time significantly overall as a result, even for the older cars.
