An Electric Car in the snow

This post is also available in: Français (French)

This blog is about how practical it is to operate an electric car in the snow. I live in the French Alps at 800m (2,600ft) and I’ve driven 10,000km in my BMW i3 over the last 9 months. It has had a fair test in the snow and ice too.

When I was 10 (1981), my Dad worked for an electric car company. Electric cars made sense to me then and have made sense to me ever since. I’ve referenced that historical vehicle at the bottom of this article. Unfortunately for some obvious and rather selfish reasons electric cars have never made sense to the rest of the motor industry. Thankfully that is starting to change quite rapidly.

I should say too that I don’t live a particularly “green” life, I do ride a bike (I enjoy it), I don’t fly much (can’t afford it) I would like to save energy (save money). I’ve always disliked conventional car engines though (ICE). Starting them up for short journeys seems wrong, both mechanically and environmentally, they cost a lot to make, run and maintain and they are dirty and smelly. I agree with Arnold Schwarzenegger too, he sums it up quite nicely in this little rant. Despite not been particularity “green” I will be voting for whichever prospective government proposes the greenest agenda. Even if that means higher taxes!

 

i3 in the cold

I had been running a VW Caravelle Minibus through my own company and for various boring tax reasons had to sell it. I wanted to replace it with a vehicle I could use for my work but that the French government would not tax to death. The French Taxe sur les véhicules des sociétés (TVS) is as onerous at that in UK (Company Vehicles Benefit-in-Kind tax) both taxes are linked to how polluting a car is, this is measured in CO2(g/km), a fully electric car emits no CO2 so fit the bill well.

I had a few cars to consider.

Nissan Leaf or the Renault Zoe, I think if I was buying a car personally as the second family vehicle I would have gone for one of these, they are half the price of the BMW and (as far as I can tell) almost as good. I wanted a company car though, that would accommodate my colleagues and represent the business out and about. I don’t think either of these fit the bill.

Mitsubishi Outlander PHEV, I live in a ski area so why not a 4×4? Mitsubishi are targeting people like me too, their advertising is all about selling to business users. I discounted this car for 2 reasons. Plug in Hybrids are fiendishly complicated things and I’ll only consider one after they’ve been more thoroughly tested on the public. And to warm the cabin on this car the petrol engine has to start, making the whole idea pointless for half the year around here!

I ended up going with the BMW i3. I was rather taken with the fact it wasn’t a converted conventional vehicle, it was designed and built from scratch. It is no heavier than a conventional vehicle (its frame is all carbon fibre, something that will attract all MAMILS) and when I test drove it I could not fault it. It came across as a very sorted car. I have the 100% electric version. I decided to forego the “range extender“, in for a penny in for a pound.

The question is, “will it work well in the Alps?”. It has a number of issues going against it.

  1. In theory the hills will shorten the range.
  2. This EV has rear wheel drive, something that has a very bad reputation in snow!
  3. Batteries don’t like the cold.

Where I live, if the road isn’t going up, it’s going down, there are very few flat bits. When I picked up the i3 from the dealer in Annecy I had to drive 100km home, over two fair sized cols, with a total ascent of 1300m. The car showed a range of 135km on the dash. The range anxiety started straight away. I need not have worried, the estimated range was spot on, the hills made very little difference. It seems the regenerative breaking actually worked! Some people call it KERS (from Formula 1) but I don’t think that is quite right.

As far as winter driving is concerned, I’m writing this in mid-January, and have driven many times in the snow this year.  I bought Bridgestone Blizzak‘s and had them fitted in November. According to the review I have linked to these should be slightly less grippy but last longer than the Nokian Hakkapeliitta’s that are available. As far as I’m concerned they are excellent, the narrow profile of the tires on an i3 obviously help in snow and the “fly by wire” automatic anti-slip, stability controlled traction that you get from a modern automatic means that I have never been out of sorts on the corners. So when compared to the other FWD cars I have owned, the i3 performs better in a straight line and from a hill start and is equal (but probably easier to drive) on the bends. The car comes with various driving modes. Comfort, Eco and an option to reduced traction control. I’ve tested them all multiple times. Your best option in the snow is Eco, the other options might be more “fun” but they are no more effective at getting up a hill. In fact I’d like the car to default to Eco. I’m not sure it will though.

It was -12C (10F) last night, generally the night-time temperature between November and March in this part of the French Alps is below freezing, an average might be -3C(26F), a minimum -20C(-4F). This car is kept outside. The cold temperatures do have quite a marked effect on the range. Over the summer I could bank on 135km from one charge but at -3C that would be 110km and -12C 100km. I’m told this could be improved by plugging the car into a high power socket at home. This would allow the car to draw more power to operate a heating circuit around the battery and to heat the cabin too. I only use a domestic socket which doesn’t supply enough power to do this. The domestic socket will only help heat the cabin [this might not be correct, please see the comments below, more investigation required!] I have resisted having the better socket fitted because of the outlay (1000€) and the running costs. Here in France we have to pay extra on our electrical supply contracts for more power. In this case another 300€ a year. We have another car in the family so I can live with this reduced range.

i3 delivered to the alps

This is the first car I have owned that will pre-heat the cabin prior to driving, this can be a real luxury, especially when there is an impenetrable layer of ice across the windscreen. 5 min on pre-heat and the windscreen will be defrosted, condensation free and the cabin at a comfortable temperature. This facility can be controlled from the key fob, your phone or programmed in the car. I find setting a departure time from my phone the night before works well. I do quite a few short journeys that with an ICE vehicle would not allow time for the engine to warm up the heating system. The heating system in the i3 copes well with these journeys.

A downside with a completely new car like this is that the lack of reasonable priced accessories. Snow chains and roof racks cost twice what they should.  As far as I can see RUD-matic chains are the best value. I have not bought a pair yet though. As for ski racks, the Sea Sucker might be the only option.  I can recommend some floor liners though. Getting in and out of cars in the snow just fills the foot-wells with salt and water. I’ve fitted a pair of these WeatherTech Floor Liners which have been excellent.

So all in all I can recommend using an electric car in the snow. Though for a family in the mountains I can only see it working as a second car. Even though it is a second car that will do 90% of the journeys required. A word of warning though, if you get as far as visiting a dealer, the first question they’ll ask is “do you have a spot to plug it in?”, they won’t work without a place to charge them up! When making the purchase you are then faced with a bewildering number of “extras”. After asking around I went for the heated seats and an additional heat pump to help heat the cabin. I think that I’d do the same again but only because I live where I do, I would not bother with either otherwise.

    I think you may be misinformed about the preconditioning. In N America it doesn’t work on the 110V 10A Occasional Use EVSE, but if your outlet is good for 10A continuously without overheating then at 230 or 240V I think there is enough power to precondition the battery as well as to warm the car. You must set a departure time at least 3 hours away and tick the box for precondition.

      John, thanks for your input. I appreciate it. You may well be right. I was Goggling the question last night and came to a similar conclusion. The trouble is I have been pre-conditioning and setting a departure time (the night before) to see if it improves the predicted range and so far I can’t see that it has made much difference. I did come across a post that refers to a hidden menu that gives access to the battery temperature. I tried that this morning but could not do anything more than reset the next date for service! I guess I need to keep a note of ambient temp VS range for pre-con on and pre-con off.

    Hi Gareth

    thanks for a comprehensive and informative article. Useful to hear your firsthand experience. As I use less than 60 of diesel a month typically an electric car makes sense for local travelling. Interesting that it is performing so well at low temperatures. Do you think that there is any general ‘strain’ on the battery that may shorten battery life or is this just not an issue with the type of battery used in new EVs?

      I don’t know the answer to that. The battery performance will decrease over its life but I don’t know if the cold will hasten that. I’d have to compare notes to another i3 driver in a more temperate climate. It’s one of the reasons I was happy to lease the car. If there is grief like that I can hand it back after 3 years. Though at the moment I’d happily keep it for much longer than that!

    I have made a note of the range the dash displays over the last few nights. It’s hard to see if the battery pre-heat is working, the main issue seems to be to do with how efficient my last journey was! If my last journey was mostly downhill then the range will be higher and if it was uphill then it will be lower. I guess this is because the car uses the efficiency of the last X kilometres to esimate future efficiency. So far I have
    With pre-con
    -1.5C, 110km
    -6C, 120km
    -2C, 125km
    Without pre-con
    -1.5C, 122km
    +5C, 132km
    +7C 139km
    It seems spring has arrived early now!

      Gareth, yes the Guess-O_Meter does use recent experience to estimate range. And it’s notoriously unhelpful. The number of battery bars is far more useful, combined with your own idea of the mi/kWh, kWh/100km, Wh/km (whichever you see on your display) for the type of journey anticipated. In mild weather and gentle terrain 20 miles/ 32km per bar is standard, say 4mi/kWh, 15 kWh/100km, less if cold, big elevation gain, hard acceleration.

    Hello everyone I’m fairly new to the electric experience having owned my i3 Rex for only six months but I would never return to a fully fossilised vehicle, the furthest I’ve managed on a full charge and using Rex is 210miles, I was thinking of a road trip through France starting at my home here in Manchester GB but was worried about the charging facilities the other side of the channel. Gareth’s report has allayed my fears somewhat and I now definitely plan to take a trip to mainland Europe, of course I will have Rex as a backup ! I not sure what I will need in the way of charging cards and alternative cables. If anyone can help it would be much appreciated. Many thanks.

      Our department has a charging pass system but I think if you are going further afield then you should look at something like this https://chargemap.com/pass I use Chargemap to locate charge points but have not used the pass. As far as cables are concerned, the new points that are being fitted require a type 2 cable https://en.wikipedia.org/wiki/Type_2_connector so that’s be easy for a BMW driver. However beware that there are plenty of old type 3 sockets, so check before you need to rely on something. I have not bought a type 3 cable or adaptor, and although this is a great resource….it is not my experience that “most” sockets are type 3. https://www.evchargeking.com/en/t3-charging-cables-for-france

    Thanks for the great article – I live in the Swiss alps and was considering buying an electric car but wasn’t sure what it would be like in the snow. You have allayed my fears!
