We have just reached the half year mark in our ownership of our electric car. We chose the plug-in hybrid version of Hyundai’s Ioniq series of new electric vehicles.
We decided on the plug-in model because it allowed us to be able to charge the car from our solar panels and drive almost entirely on sunshine. This is very important to us as we are committed to lowering our carbon foot print where ever we can — without being silly about it, or being forced to live in a cave and only eat cereals and drink water. The life that we live would be recognisable as being more or less ‘normal’ modern, first world, middle class, living by most.
We chose the plug-in version over the full electric model because we only have the one car and we need to be able to drive long distances a times. Like driving up to Sydney and back, or down to Canberra from the Southern Highlands. It’s not that often, but a few times a year. We didn’t want to be constrained by having to stop and charge the car before being able to drive on, or drive home. The cheaper range of electric cars only offer 200 to 230km range at the moment. Not enough to get us to Sydney and back without having to recharge.
The hybrid version of the Hyundai Ioniq allows us to revert to petrol power to extend our cars range and eliminates ‘range anxiety’ completely. When the fuel tank and battery are both full, the car has a range of over 1,100 kms. No anxiety there, it is in fact twice as far as our old, and very fuel efficient, small car could go on a tank full.
So what have we achieved so far after 6 months of driving. We have filled the petrol tank twice and we are still only half way through the 2nd tank full of petrol. Thats $75 worth of petrol in 6 months. We have driven just short of 6,000kms so far. So nearly all of those kilometres have been driven on sunshine. We filled the car with about $50 worth of petrol at the end of Feb and again at the end of April, again with $50 worth of fuel. We are still using that last tank full. It’s just under half full still. All the rest of the driving has been done on sunshine.
This is possible because we installed solar power in 2007, as soon as it became affordable to do so. It wouldn’t be ethical for me to buy an electric car and plug it into a coal-powered power point. That would be useless. It would be swapping from driving on petrol to driving on coal! An appalling thought in these carbon constrained times of climate crisis and global over heating.
The most recent email ‘monthly report’ that I got from my cars dashboard computer into my phone tells me that we have been driving very efficiently on our sunshine.
So we used 1.78 litres of fuel over the month and drove 697 kms, this equals 391.57 kms per litre of petrol. Pretty impressive, if I do say so myself.
Now that we are more used to owning the car, we have found that we can make two trips in one day easily. We can go to Picton and Tahmoor in the morning and then return home for lunch and then go to Mittagong and Bowral in the afternoon. The car charges easily in the full sunshine of the middle of the day while we have lunch.
Last week we went out to the movies two nights in a row, and were able to re-charge over night in the dark from our stored sunshine in our ’Tesla’ Battery. The battery then re-charged it self in the morning when the sun rose. I didn’t have to do anything to coordinate this.
Sometimes we recharge the car directly from the sunshine in the morning, if we know that we don’t have to drive anywhere until the afternoon. We can go out again in the afternoon and recharge from the battery on our return
So here we are just past the solstice. The sun is at its lowest angle, for the shortest number of hours and we are still making 4700 watts from our solar panels . This is against the maximum of 6,000 watts that are possible in high summer with the sun up at its apogee. Not too bad!
You can see from the screen-shot below what a winters day looks like and how we charged the car from the battery after sunset.
What is important to notice here is that we sold significant energy to the grid (shown in white) as well as running the house (in blue) and charging the car (in green). The yellow is the sunshine collected, you can see some clouds came over from midday/early afternoon, but we still made a small profit.
This will be the last report about the electric car for 6 months. I will write something more after the first 12 months are completed.
The electric car scene is set to change very rapidly in the next few years as more models come onto the market, But I feel that it will be a very longtime before a fully electric car with a 600 km driving range will be available for the under 40,000 price tag. Maybe by the time this car runs out of warranty in 8 years time, then something better will be available and affordable? I look forward to being spoilt for choice. For the mean time, we are very happy with our decision to go driving on sunshine.
