2 years Tesla Model S – The good, the bad and the beauty

2 years ago I got my Model S at Brussels Service Center. In those 2 years I drove over 80.000 km with it. Here are some of my thoughts on electric driving and Tesla

What are the driving costs?

This is what I spent on my Tesla Model S for the last 2 years.

  • Tyres : I’m still on my original set, but I bought a set of extra wheels and winter tyres for about 2.000 € at the local tyre shop
  • Insurance : 1.900 € per year for a full omnium insurance
  • Service : I paid 2.200€ for a Tesla Service contract for 80.000km
  • Electricity at home: I consumed 18.255 kWh of energy @ home with an average energy cost of 0,16 €/kWh it totals 2.920 €
  • Public charging : 34 € 

My thoughts on Electric driving in general

My ideas on electric driving haven’t changed a lot since I first drove an electric car. The torque being instantly available is very pleasant. Also the Energy regeneration which slows you down when you release the throttle makes it very fun to drive an electric car. It allows you to drive only using your throttle, which is called ‘one pedal driving’. Very relaxing in traffic jams.

Not having to refuel is also a big plus. You just plug into your charging station when arriving home, and your car is full in the morning. Hard to think I once worried if I’d make it home without refueling.

Battery degradation

There was an initiative on the Tesla Motors Club Forum to log our remaining range during time. Here are my figures highlighted.

The 2 peaks you see where registered when I had a loaner battery in my car.

As you can see I’m absolutely not the best in class. I have about 92% of my original battery capacity available. I’ve always charged my battery up to 75%, and did this daily. I will now change this and charge to 90% and do it every 2 days, hoping I might normalize my degradation a bit. We’ll see how this evolves.

Edit : I received some info on the Tesla owners group on Facebook. Charging your battery up to 75% causes some battery inbalance. To get good reading afterwards, you’d need to charge it to 100% and drive it empty, and repeat this a couple of times. So I’ll just keep charging him to 75% as I did

Tesla and its service

In those 2 years my car has had its issues. But that’s what I expected driving a semi-prototype car. I have one of the early European production models.
Here’s an overview :

  • 12V Battery replaced
  • Main battery went in for a complete revision
  • 2 drivetrain replacements
  • Battery heater replaced
  • USB port replaced

All these things were done under warranty, and most of the repairs were initiated by Tesla themselves. I never asked for a drivetrain replacement, but they thought it made too much noise. Same for the battery heater. They noticed a malfunctioning during maintenance service and replaced it. For the 12V problem an error message popped up to contact the service center. It was replaced in an hour or so.
The main battery was replaced after I got stuck on my driveway. The car wouldn’t start anymore. Tesla provided a replacement Tesla and found the battery problem. They fitted a loaner battery, and after a couple of months I got my original battery back, and never had a problem since.
The USB port was still functioning, but the black spacer inside the port was loose.

In short I am very happy with their service, but I know this was part of their warranty. This warranty just ended, so next time my battery heater goes, I’ll have to pay it myself. But that looks only fair to me.

Tesla’s referral program

has been continued. People using my link can also use my gear (CHAdeMO charger, Roof bars, Juice Booster, Ratio Charger) when needed. Uptill now there were 2 people using my link. Hereby thanks to do those 2. If anyone else uses my link, feel free to contact me.
