Living with an electric car

I promised a follow up on living with an electric car. Here’s how we are getting on.

It has been a mixed bag, mostly positive with a few annoyances.   Here are a few highlights:

Quiet

There’s a quiet effortlessness about an electric car.  It is a different feeling to drive completely.   I was used to a roar of engine noise meaning power.  There’s none of that at all.  A bit more like putting the foot down and it takes off with a hint of an electric whirr.    Or touch the accelerator and it glides along silently.  Mind you, some of this silence will be just because it is a new well-insulated car.

Not smelly

When operating this car doesn’t smell. I also never hang around fuelling stations. Now I notice exhaust and petrol fumes on other cars.  This is a bit like it was when people stopped smoking in public and suddenly noticing smelly second-hand cigarette smoke when walking behind a smoker on the street.  So now I notice car pollution. Before I just didn’t notice.

Reliable

The whole car seems pretty simple and reliable. There’s a lot less to go wrong.  No emissions system. No real gearbox.  No catalytic converter, radiator, exhaust pipe, water pump, ignition, fuel injection, turbocharger.  Less to go wrong.  Instead you have an electric motor, a simple gearbox and a bunch of batteries.  Nothing has gone wrong so far.

Low cost per mile

So we charge overnight at home, so we’re paying off of our regular power bill to charge the car (with Ecotricity offering a small grant/discount for electric car owners).  Out and about charging is either free or pretty low cost so far.  So, the cost of fuel seems pretty close to zero. The previous £70 in fuelling the old petrol car has now pretty much disappeared.  This is a decent saving.

Range difficulties

The electric has a much smaller range than the old petrol car.  And the faster I go, the shorter the range, so motorway range (when range really counts) is a lot less than old slow road range.  This doesn’t matter at all going in and out of town, a 5 mile round trip.  But motoring across England it does matter.  It means both limiting maximum speed to say 60 or 65 and stopping regularly (say every 50 miles) for a ½ hour of charging.  It is something like this: the Motorway range is 50 miles and the slow road range is 70 miles.  Slow going.

I really want something like a Tesla with a 200+ mile range. That’d make it barely noticeable.

Home Charging

Home charging is easy for us, we have off-street parking and a garage with power. Simply a matter of plugging in the lead in the garage, then drive the car up, park up in the driveway and plug it in.  This feels just like putting the phone on charge every night.  The car will fully charge overnight from a regular 13A socket, so that is simple.   I guess we charge it every 4-5 days in normal life.

Patchy Charging Infrastructure

So I don’t need petrol stations -- but I do need fast chargers out and about and things for people to do while the car is charging.  So more likely you want chargers at shops and the gym and motorway services.

There are networks of charging points emerging -- they are being installed across the UK.  Right now there are not enough chargers out there so it is possible to get caught where there is a charger offline.  And because the technology is new, chargers aren’t as reliable as you’d expect.  This means that a whole trip can be aborted when a key charger is not in place.  Or alternatively a trip can slow down because I have to queue up to have a go at the charger.

We’ve resorted to careful planning for the longer trips now -- checking charges are available and having a backup in case something is not working.  This is a bit of a faff too, as the mapping of charging points is contains across multiple services and they are all slightly different.

Community

Clearly this is all for early adopters. And that means there’s a community aspect to this built out of the novelty of the whole thing and needing to exchange stories.   

Turning up at a  public charger means you’re likely to run into people charging or waiting to charge -- and there’s a chance to have a chat about chargers, cars, range, cables.   This is quite an enjoyable part of the whole thing -- as long as you’re not in a hurry.  Think back to the stories of the introduction of motoring.  A bit like that.

In summary

This is early adopter stuff.  If are an early adopter then consider it.  Otherwise wait a couple of years for extended range and simplified charging networks.  There is no doubt the electric experience is a good one when it is all lined up.

I think it is totally worth doing, though with a couple of caveats:

  • Without off street parking it is going to be really hard.  You’re going to have to use public chargers for most of your charging.

  • Make sure that the basic range suits your commuting/regular trips.

  • Beware of buying an electric car -- I’d lease until range becomes less of an issue.   Battery technology is improving rapidly.

You've already bought your last fossil-fuel car

We've just spent a week trying out an electric car.  This was the last confirmation I needed.   It is clear that the petrol / diesel powered car is on the way out.  Let me explain my thinking:

  • A basic electric car is mechanically simple; A battery and an electric motor.  There's no large metal box full of mechanical parts in which fuel explodes. There's no complex ignition, exhaust, or cooling systems. These cars are easy and cheap to service.
  • The complexity comes in charging and taking charge out of the battery, and in getting efficiency from an electric motor.  We're doing a lot of society-wide work on battery technology (like, in smartphones/tablets/everything). I'm expecting significant improvements over the next few years.
  • The fuel cost per mile or kilometre is say between 1/5th and 1/10th of that of petrol or diesel.
  • Battery charge density and therefore range is improving fast, as is charging speed.

Better organised and complete charging infrastructure will emerge.  Electric car range will increase.  Doubling of  the currently ~100 mile range to 200 miles will make most journeys feasible.  I'm confident people will get very interested when the fuel and maintenance costs of electric cars start to become clear.

That's seems to be at most five years away.  At that point, a petrol/diesel car might start to seem an expensive luxury.  Petrol/diesel resale values may fall sharply.   Fuel use will start to decline.   About 60% of the total energy used for transport is personal vehicles.  This would hurt fossil fuel providers, so maybe holding those fossil fuel shares is not a good long term bet.

So, right now, here are my tips for surviving the change:

  • Don't buy a new petrol car. Look out for a bad resale price in 5 years, especially for an ordinary car.  Are you buying your last petrol car ever?
  • Don't buy a new electric car just yet. Lease an all electric or plug-in hybrid for a few years. There will be annoying and adventurous times as long distance charging networks stabilise. Allow the basic electric range to double (to say 200-250 miles) then consider a purchase.

We've just arranged a lease on a Nissan Leaf. It should arrive next week.  I'll update how we get on.
