Gone Electric

Background
In October 2010 I had solar panels fitted to my roof at home. Just a small installation of about 3kW peak under the Feed In Tariff, then called Clean Energy Cash Back.

At the beginning of November last year, according to my calculations, they had paid for themselves through Feed In Tariff payments, export tariff payments and the value of the electricity generated that we use ourselves.

Time for a new project. I've been looking at electric cars for a couple of years. I had several requirements that needed to be met before I could take the leap:


  • The car had to be able to complete my commute of 85 miles a day on a single charge.
  • The price had to be comparable with a mid range fossil fuel car.


The Tesla Model 3 seemed like the first car that was going to meet the requirements, so I put down a deposit and joined the queue. After six months, it seemed apparent that this car was not going to be available for some time (if ever) so I started looking at the new Nissan Leaf. In august of last year I canceled my Tesla and ordered a new Nissan Leaf. I was told it would probably take until January to arrive, and yesterday I picked it up.

My First Journey
Driving it of the forecourt of the Nissan dealership, it had almost a full charge and said about 180 miles range available. Unfortunately, I had a meeting to be at, so had to drive at motorway speeds. It appears the 180 miles range does not hold for my normal driving style. By the time I had arrived (a distance of about 40 miles) the available range had dropped to 90 miles.

In the Leaf's defence, I had had the heating on at the start of the journey, it was a cold day and I had not switched on all of the energy saving features in the car, however, without a charging point at work, I now had range anxiety. With a home journey of 45 miles and that rate of discharge, I was not sure I could make it home.

Unluckily the day I had chosen to pick up the car was also the coldest day of the year so far and the first day of snow, however, as I knew that I was on the edge of the range that the car seemed likely to make, I decided to go without heating. Still, as I made my way home the range was reducing at about double the miles I was doing.

Part of my journey home takes me on to the M4, and looking at the map of charging point, I saw that there were several provided at a service station I would be passing. I thought if I made a short stop I could top up the battery enough to get home.
I had already ready installed the Ecotricity Electric Highway app and thought this would be a painless process but no. I found the charging points easily enough, pulled in and opened the app on my phone. It hung. Just the initial splash screen. I closed it and tried again, same result. I rebooted the phone, no luck. So in the end I gave up and decided to take the chance I may run out of charge before home.

Once off the M4, I turned on all of the eco options in the car. At the lower speeds and with these options switched on, the miles started to match the range and it looked like I may make it.
By the time I was 10 miles from home with 25 miles range left, I finally felt confident enough to turn on the heating. I made it home with about 20% battery remaining.

Now a day later, how do I feel ?
I think driving is going to be different. This is not a like for like swap with my old diesel Volvo.
I will have to take more notice of my driving style and I will reserve judgement on whether the move to an EV was a good idea until I have made a few more trips and compare my electricity bill increase with the decrease in my car fuel bill.
