Just another tax-dodger.

One of the more enduring myths about electric vehicles is that driving a full battery electric vehicle (BEV) means a worry-filled trip waiting to unexpectedly run out of energy, with no chance of a recharge to get home again.

It’s a myth encouraged during the recent election campaign (“you’d be better off walking to Dubbo”) and ever since. But early adopter battery electric vehicle owners have long known that this is not the case.

Running out of charge turns out to be no more likely than running out of petrol. (Plus, if all else fails, power points are a lot easier to find than a jerrycan, funnel and organising a lift to/from a petrol station).

The Range Anxiety label was created when those first BEVs were put into the hands of motoring writers and others unfamiliar with the technology.

Unsurprisingly, they approached them like an internal combustion engine (ICE) car and followed the paradigm of refuelling only when forced by a low fuel warning to go to a refuelling station. They were then apparently surprised that a petrol pump nozzle didn’t fit into a charging socket.

(It does make me wonder how many early ‘horseless carriage’ owners seemed put-out when their newfangled internal combustion engine car would not refill itself when parked next to a pile of hay …)

And just like moving from hay mangers to petrol pumps, the change from ICE to BEV and battery charging requires a paradigm shift in thinking about refueling.

For the vast majority of trips, you no longer have to go out of your way to find a petrol station, stop, sometime wait  and then stand by your car as it refills at a petrol station, and then pay for the privilege of standing in any weather to do so.

For short range trips, which are by far the most common, if you recharge when at home or stopped at your workplace or shopping – range is never a problem.

But it did need you to shift your thinking from forced refilling stops to ‘opportunity charging’ when out and plugging in to charge when at home.

It  is true that early BEVs such as the Nissan Leaf or Mitsubishi iMiEV had only a range of 100–140km – limiting them to a suburban driving role with the need to keep an ICE vehicle for longer trips.

That, of course, did not stop their more intrepid owners doing some very long trips indeed – as exemplified by the many contenders for the Australian Electric Vehicle Association’s Glen George Trophy.

(Awarded each year at the AEVA national EV Expo for long-distance BEV traveling to the event).

As an example, in 2017 it was awarded to an iMiEV that traveled from Adelaide to Devonport: only just beating a Leaf traveling from Port Stevens in NSW, with both trips being done before DC fast chargers were available outside of city centres.

It is also worth noting that BEVs never ‘suddenly’ run out of charge: they give constant reminders of the remaining estimated range.

They also offer (or even automatically slip into) eco modes for low battery and ultimately apply a ‘turtle’ mode to get you a few kilometres more to a power point/EVSE is you persist in ignoring all other warnings.

(This is akin to an ICE car giving you a ‘turtle mode’ of an extra half litre or so when the car coughs to a stop).

However, the Range Anxiety label was created, and it stuck as a description for the inability of BEVs to travel long distances easily, and the inability to access DC fast-chargers on major (or in fact any) out of town routes.

But that was back in 2011/12, and a lot has happened since.

Nowadays, you are less likely to be surprised by a low fuel warning in a BEV than in an ICE vehicle – and far more capable of reaching an EV refuelling option that meets your needs if that happens.

So what’s changed?

Firstly, BEV batteries are now three to six times the size of those early ones (iMiEVs were 16kWh and early Leafs were 24kWh: the current Kona electric is 64kWh, the Model S Long Range 100kWh).

With efficiency improvements as well, these cars are capable of easily doing 400 – 600km on a full charge. For most daily usage, that means the occasional overnight charge is plenty.

Opportunity charging is a thing of the past – unless you want to.

For those without off-street parking, opportunity charging or a once-weekly DC fast-charge to 80% would still be plenty for a week of driving.

Another improvement is in the data provided by the car itself.

Dashboard range estimates have evolved well beyond the GOM (Guess-O-Meter) as the early Leaf range-estimators were nicknamed.

The data readouts in a BEV (fig. 1) are now direct analogues of the existing gauges and data provided in a modern ICE car. Instead of a fuel gauge, you have a state-of-charge gauge.

Instead of a litres/100km usage estimate (either instantaneous or averaged for the trip), you have kWh/100km.

Also, just like an ICE car, you get remaining range estimates based on current driving patterns and remaining charge. (And these are proving to be very accurate – unlike the early Leaf GOM).

On top of this, modern BEVs with their SatNav systems are able to locate and direct you to the nearest charger if you ask it to.

(Unfortunately, with both DC and AC charging networks rolling out so fast now – the moment they go into an EV computer they are out of date – but Apps like PlugShare fill in that gap).

A third change is the roll-out of DC fast chargers along the major interstate routes – with many more to come.

DC fast-charging to 80% in 20 – 40 minutes is now the norm along these routes. (Just the right amount of time to get in that coffee, meal and toilet stop and safely proceed again).

In addition, refueling a BEV on a long trip is super easy (see fig 2) as it will tell all you need to know to let you go for coffee or a meal whilst it is charging. (Plus don’t forget the phone apps that come with many new BEVs).

To be able to monitor your car charging from your chair, bed or restaurant is so much easier than being a ‘pump-attendant’ to your car waiting for it to fill up).

(Vehicle plugged into a 50kW DC charger).

Current range:top (297 in this case)

Time to 100% charged: above battery image.(1h, 8 min)

Time to 80% charged: underneath battery image.(16 minutes)

 Instantaneous charging rate: at bottom. (41kW)

In summary, it is high time to call ‘Time’ on Range Anxiety.

Certainly, in my 12,000km so far of driving a Kona electric – including one circumnavigation of Victoria, two trips to Sydney (one including a trip to Coffs Harbour and then back to Melbourne via Dubbo to avoid bushfires on the coast) – I have not been any more worried about running out of charge than I would have been for running out of petrol.

The difference is a change of mindset: instead of looking for petrol stations, I look for my refueling options on PlugShare, DC charging network Apps or just plug-in at my overnight stay.
