Many people are have a negative view of EVs based on incorrect, or outdated information.
Conversely, some pro-EV people will take any fact or viewpoint that isn’t absolutely pro-EV and try and argue it away whilst claiming if only we all drove EVs the world’s problems would be solved, and any problems with a move to EVs are trivial. So if you’re expecting this article to be unremittingly pro-EV, well, sorry.
So now I’ve upset both sides of the argument, there’s a middle ground, and that’s what I’m trying to address in this post and my videos below:
- Little need for public charging – realistically, if you just do daytrips and around-town errands or commutes, you can do all your charging at home off your standard 240v – most cars are idle at home for the majority of their life, and many owners very rarely use any public chargers. So public charging infrastructure is much less of a problem that first thought.
- Interstate trips not yet as easy as ICE – if you do need to go further afield, DC fast chargers are becoming ever more plentiful. But, interstate trips in an EV are simply not yet as quick and easy as an ICE trip. EV enthusiasts would beg to differ, but they’d have plenty of time to think about it during their trips. The longer the trip, the more remote and the heavier the load, the greater the difference between EV and ICE. So a Tesla driver that stops once for a supercharger on a freeway isn’t really any slower than an ICE if the latter has a long stop, but towing up the Birdsville track is a different story. As someone that used to do regular Melbourne-Canberra runs at the speed limit with aircon or heating on with a 15m stop, using a range of long-distance driving techniques…that can’t yet be done in an EV. Of course, EV owners would say I need to stop longer anyway therefore no problem, an example of EV-centric thinking. But what if there are two or three drivers sharing the drive, or the chargers are busy, or you feel like a stop where’s there’s no chargers? The stops on a long trip should be dictated by the need of the driver, not the machine, and right now, that’s not the case with EVs.
- EVs tow well, but not for long distances and they can’t do the job of a diesel 4×4. I have towed with a Tesla, went very well…briefly. Right now, EVs are good for short-range towing as they’re powerful, heavy and slow down nicely under regen, but no good for towing long distances as their range suffers greatly (will explain why in a while). Many of my readers/followers/viewers own drive and tow long distances, as do I – I write this in a caravan I towed from Melbourne to NSW, a journey of 9 hours I did on a single (long-range tank) fuel fill, so this is important to us. However, if the likes of Atlis and Rivian come good on their promise, towing with EVs may become practical, or maybe hydrogen will take over for that sort of use. More here:
- EVs are not yet cost effective compared to ICE cars for the majority of owners. The price difference is often far too great for comparable models, and the lower run costs don’t make up the difference unless you factor in pro-EV assumptions such as hugely better resale for EVs than ICE, lots of EV-friendly mileage, or zero-cost electricity which usually ignores the cost of infrastructure such as solar to get that low cost. But, it’s getting closer and closer. EVs won’t need to sell for the same buy price as ICE to be a better 5-year ownership cost because their run costs are much lower – fuel and servicing, so the longer you own your car and the more mileage you do, the more cost-effective an EV becomes (explored in video below).
- It doesn’t matter how ‘dirty’ the electricity is, the modern EV is still better for the environment. In short, petrol/diesel requires a lot of effort to extract, then transport, refine, transport again. Also, ICE cars don’t convert much of the energy in a given quantity of fuel to propulsion – an EV converts around 80% of its energy to propulsion, an ICE only around 25% as a lot of the energy is lost in heat, and some more in friction due to all the moving parts. An EV also recovers energy through re-gen when slowing which greatly helps its energy efficiency. So, even in coal-powered China EVs come out ahead. But that ignores build lifecycle, so…
- Are EVs better overall for the environment? Almost always, yes and it’s improving. Basically, creating an EV generates more emissions than an ICE due to the battery manufacturing, at the moment. However, once the cars are in use, the ICE has far less emissions, possibly zero depending on how the electricity it uses is generated. So, at some point the EV is overall better for emissions. The ‘some point’ is variable; depends on many factors such as the size of the battery, how the EV’s electricty is generated and so on. Here’s an example graph from Volvo showing one of their ICE cars vs their EV, with three different EV lines reflecting different electricity generation scenarios:
- Old EV batteries aren’t wasted. This is one area the EVs haven’t been great, but now EV batteries are recycled as there’s a real incentive given the precious metals involved. There is also tech like battery management systems which ensure the battery is operating in the right temperature zone and that prolongs its life. The Kona battery (see videos below) is warranted for 8 years. And, even if the batteries aren’t recycled they may be re-used for home battery systems where you charge the battery from renewable sources and draw down the power as required.
- Batteries don’t need replacing; Tesla and others are looking at lifetime batteries, no replacement, and ‘lifetime’ means at the moment 8 years or 240,000km with 70% capacity (Tesla), and in the future, up to 1.6 million km. How many modern ICEs are going to last that long without major rebuild work? None, I’d suggest.
- Update your EV assumptions – tech changes…you can’t compare a first-gen Nissan Leaf of 2010 (117km range) with a 2021 Hyundai Kona EV (484km range) any more than it’s fair to compare an aged LandCruiser 60 Series with a modern 300 Series. But wait…the time between the two is different! Yes, that’s because EVs are changing more rapidly than ICE, so we’re at the point where every new release is a big improvement on the previous.
- EVs can help the electricity grid – it’s called V2G, or Vehicle to Grid. In times of peak demand, your EV can power your house. Then, when demand is less, the EV can recharge. And, in the event of a power outage, your EV can act as your electricity supply.
- Consider ICE partial replacement costs. If you run an ICE for 200,000km you won’t need to replace the engine…but you may well need to rebuild it, and will certainly have replaced many parts of it along the way. Starter motor, alternator, spark plugs, fluids, belts, pulleys, tensioners not to mention the transmission. With an EV any battery replacement cost would be nothing, then a lot in one go, whereas with ICE the component replacement costs are smaller but more frequent.
- Fuel security. Australia has around 2 weeks worth of fuel at any one point. Basically, we are entirely reliant on a steady stream of oil tankers arriving at our shores. All an enemy need do is stop those tankers and we’re stuffed. Electric vehicles would mitigate that risk.
- We won’t “brown out” the grid if “everyone suddenly switches to an EV”. Firstly, EV adoption won’t happen overnight, secondly it’s easy to schedule charge EVs overnight when it’s off-peak and there’s surplus capacity. And, Australia’s total electricity consumption is reducing over the last few years. More on that one here:
- Half of the world’s lithium is mined in Australia, not overseas. Historically, the process hasn’t been very environmentally friendly but that’s changing. If you were wondering about slave/child labour, that’s cobalt in Africa…and things are changing there too.
- Copper production is critical to EVs as copper is one of the best conductors – an EV uses more than double the copper of an ICE, according to Reuters, or three times according to other sources. EV charging infrastructure also relies on copper, so there’s got to be enough supply to meet demand. I’m not clear on whether that’s possible or not.
- Many people say EVs are complex. No, they’re not…they’re far simpler and even have fewer computers than any ICE vehicle. Much less to go wrong. It is modern cars that generally are complex, not specifically EVs. There’s a LOT of complexity in the modern ICE just dedicated purely to emissions controls; think EGR, DEF, cats, idle-stop and more, let alone the massive complexity of the ICE itself.
- Australia has a lot of off-street parking which is ideal for charging EVs as the cable doesn’t get in the way of the public, as compared to European city or even suburb dwellers. However, for inner-city residents at-home charging is a challenge. I would find it a major pain to own an EV if I couldn’t charge it at home whilst I slept.
- “But transport is only 24% of the world emissions, and cars are only 13%” or similar. Sure, it’s wrong to claim that if we switched to EVs overnight the world’s problems would be solved, far from it, despite what the EVangelists claim. But every little bit helps, and cars tend to pollute where humans live, with consequent effects on health. So the effect of reducing car emissions is, from a health perspective, greater than the percentage of emissions would suggest.
- EV fires are dangerous. Yes they are, and they can be worse than ICE fires but there is evidence to suggest EVs are less likely to catch fire in the first place. The best place to read more on this is EV Firesafe.
- What about hydrogen? That’s got a lot of advantages relative to electric, namely lower weight, greater range and quicker refuelling so is arguably the future. But, chicken-and-egg…there’s no hydrogen infrastructure, so few cars. I think that we’ll start to see hydrogen used in trucks which work from a night base, and that’ll expand to interstate trucks, and then beyond to cars.
- EV resale? A current dream of the EV crowd is that the resale value of ICE vehicles will dramatically drop as EVs take over. As ever, there’s nuance here. I’m really not convinced because a) EVs cannot replace all vehicle classes any time soon, e.g. diesel 4X4s, b) there is a massive emotional attachement to ICE vehicles and c) the average car-buyer consumer needs to understand and trust EVs, and that buyer isn’t there yet. The ICE cars most likely to be hit for poor resale – eventually – will be the cheap runabouts that nobody cares about that can be replaced by EVs right now; small SUVs, roadcars – but for the rest I think resale will be fine for a while, notwithstanding the effect of the COVID tax wearing off.
- Did you know? Less than 2% of the new cars sold in Australia are electric, but in Norway it’s more like 75%.
And think about this. We’re switching from petrol chainsaws and mowers to electric, and from cord power tools to cordless. I never want to use a petrol chainsaw or mower again, and no longer own either. All that is driven off improved battery technology, and cars are no different.
Here’s a look at EV vs ICE using the Kona as an example, complete with cost comparison:
And this one takes a look at EV charging.
Finally, Tesla recently set the first official EV lap record at the Nurburging. In this video I compare that lap against the one set by a pre-production Porsche Taycan, and a BMW M5 CS to give an ICE comparsion.
