EV Buyers Guide

How do you pick the best EV from the increasing range of electric vehicles on offer? It helps if you know the practical features that matter to everyday EV owners.

WATTever’s EV Buyers Guide outlines the eleven key vehicle features that you should be bear in mind when shopping for an EV. These are things that you’ll soon discover make EVs hugely exciting (and on occasion, just a little frustrating). Some may be essential for you. Others are ‘nice to haves’. All are worth considering.

Over the last decade, I’ve purchased and owned four EVs – a Tesla Model 3, Hyundai Kona, Nissan Leaf Gen 1 and a Mitsubishi Outlander PHEV. Plus, I’ve had the opportunity to drive many other models, including the Tesla Model S & X, Nissan Leaf Gen 2, Renault Zoe, Holden Volt, Hyundai Ioniq and Jaguar I-Pace. I’ve realised there are features that daily EV owners value and use. However, these features are often missed or underrated in car reviews. This situation isn’t surprising because very few journalists own an EV or rely on one every day.

Eleven essentials when choosing an EV

Weighing up these features will help you determine the most suitable model from your shortlist to match your motoring needs. Whether you are reading reviews or taking a test drive – these features are worth thinking about, asking questions and researching how your prospective EV purchase stacks up.

  2. Range
  3. Charge Rates
  4. Efficiency
  5. Dedicated design
  6. V2x Support
  7. Over-The-Air Updates
  8. Remote Access
  9. Battery Management (heating/cooling, charging optimisation)
  10. Battery Warranty
  11. Purchase Incentives

1. Performance

Electric motors provide maximum torque at low RPM. As a result, EVs respond almost instantly to the accelerator. Torque is a massive factor in making EVs fun to drive. Car enthusiasts are discovering that the E in EV could equally stand for Exciting. Even middling EVs will accelerate from 0-100kph in under 10 seconds, while performance-oriented AWD models can hit 100kph from a standing start in under 5 seconds. Like ICE vehicles, EVs with Rear Wheel Drive (RWD) and All-Wheel Drive (AWD) provide better acceleration and control than Front Wheel Drive (FWD). Many EVs also offer different drive modes (e.g. Eco, Normal, Sport). These modes adjust the throttle (and occasionally steering) response to better suit the driver’s preference.
EV acceleration and performance EV Buyers Guide
Electric vehicles also offer regenerative braking – which recaptures energy as the car slows. And like accelerator/throttle response, different EVs implement regenerative braking in different ways. Some offer ‘single pedal driving’. In this mode, when you take your foot off the accelerator pedal, the vehicle will slow down and come to a stop. Additionally, some EVs have different levels of regeneration from low to high to suit driver’s preferences. Drivers used to ICE vehicles will find the regenerative braking different at first. However, with familiarity, many prefer higher levels of regenerative braking. This ‘one pedal driving’ allows EV motorists to modulate speed up and down with one pedal. When hard braking situations arise, then the brake pedal comes back into play.
Regenerative braking
When test driving an EV, it’s a good idea to try all of the drive modes and regenerative braking levels to see how they suit your driving style.

2. Range

When it comes to range, EVs have come a long way. The distance an EV can travel on a full battery – is a combination of vehicle weight, efficiency and battery capacity. Cars offering larger battery capacities will travel further given a similar efficiency and weight. Generally, 250-350km of highway range (at 110kph) is sufficient for most people who take a break every 2-3 hours. Then fast charging rates come into play. Fast chargers allow you to get back on the road in a short time (typically under 30 minutes).

Are EV range numbers realistic?

In Australia, EV ranges are based on the WLTP rating system. This rating includes a mix of driving speeds and allows comparison between vehicles. Range ratings can be readily met or exceeded when driving smoothly at 80kph or below. That’s because EVs are more efficient at lower speeds where there is lower aerodynamic drag. However, for highway driving at 110kph in Australia, the ‘real’ range would be as low as ~70% of the official WLTP range in mild conditions.

Can we take a serious road trip?

For most EVs, more stops are necessary on long-distance trips than for an equivalent ICE vehicle. But this doesn’t stop the fun. Driving from Sydney to Melbourne can be comfortably completed in EVs with a highway range of 250+km with 3 or 4 stops. For example, the Tesla Model 3 SR+, which at the time of writing costs ~$59K driveway in NSW (after rebates), would make the trip in 9h 50m. This time includes four ~20-minute stops at fast chargers at Goulburn, Gundagai, Wodonga and Euroa. The result is very close to the equivalent time for any car driving this distance when you factor in the inevitable petrol, food, coffee and ‘comfort’ stop(s).

How much range do I need?

A handy tool you can use to help work out what EV would be suitable for your long-distance driving needs is A Better Route Planner. Set the start location and destination. Then the software automatically sets a route through charging stations to get you to your destination in the shortest period. You can select different EV vehicle models and see the impact. These practical examples are an excellent way to figure out how much range you need. EVs with larger batteries will be more expensive. So it’s worth checking to see what you’ll use.

3. Charging rates

Electric vehicles offer two forms of charging – DC (Fast) Charging or AC (Slow) Charging. Fast chargers allow charging rates up to 100km range in 5 minutes or literally around 1,200km of distance per hour. Slow charging adds up to 100km of range in an hour. So, for trips that exceed your vehicle’s range, you’ll want to use fast charging stations to get back on the road quickly. Slow charging offers you the convenience of being able to charge for a lower cost. Whether your at home, work, or a shopping centre, there are large periods of time when a car is idle and charge time isn’t an issue.

Fast charging

The best way to compare charging rates is to see how many kilometres of range gets added for each hour of charging.

For long road trips, you’ll want to fast charge. Good fast charging rates are over 600km per hour. Or about 200km in 20 minutes. In our experience, a ‘driving to charging rate’ of more than 6:1 should mean a 20 minute stop every 2 hours and a pretty relaxed drive and a Sydney Melbourne run of just over 10 hours.
Fast charger EV Buyers Guide

Slow charging

Electric vehicles come with onboard chargers that allow you to top up your battery:
  • very slowly (20+ hours from 0-100% @ 15kph range added per hour) from a standard three-pin Oz socket at a rate of ~2kW; or
  • slowly (4-10 hours @ 50-100kph range added per hour) from a faster charging station at a rate of 4-22kW.
AC Charging above a rate of 7.2kW (230v @ 30A) requires three-phase power. Almost all current EVs offer 6kW+ AC charging. Which means you can easily charge them overnight. If you’re an Uber driver or need to charge quickly at home, then higher-powered charging can be handy. But for most people, 6-7kW is sufficient using a dedicated charging station installed in a home with standard single-phase power. Many owners start with slow 2.4 or 3.6kW charging. Because they can easily add 150km of range overnight, they find they don’t need faster speeds.
Slow charging EV Buyers Guide

4. Efficiency

Electric vehicles store relatively small amounts of energy compared to petrol and diesel vehicles, so efficiency matters. An aerodynamic design is essential in maximising the range of any EV. Boxier vehicles like the Hyundai Ioniq 5 are less efficient than more streamlined models like the Kia EV6. Larger EVs like the Tesla Model X will be less efficient than smaller EVs, like the Tesla Model 3. EV manufacturers offering less efficient vehicles will need to add larger battery packs to compensate. However, the extra weight of the larger battery pack compounds inefficiency. Plus, this ultimately increases the costs of the vehicle. Compare a car like Hyundai’s Kona (70kWh nominal battery) that offers a similar or larger range to a less efficient EV, like Jaguar’s i-Pace (90kWh nominal battery pack).

The sweet spot for distance.

EVs with smaller (therefore lower-cost and lighter) battery packs can offer high efficiency and better handling. Couple that with the fast charging, and there’s a recipe for quicker long-distance trips. For example, the Tesla Model 3 offers excellent range, efficiency and fast charging. Add to this the AutoPilot/Autosteer function and an EV option that excels at quick, relaxed, long-distance driving.
Efficiency EV Buyers Guide

5. Dedicated design

Many automotive manufacturers expanding into EVs use a shared platform (chassis) to span electric, hybrid and petrol/diesel drivetrains. It keeps the cost down but means the vehicle design has a degree of compromise. First-generation EVs from automakers typically extend their existing platforms for petrol/diesel vehicles, e.g. Hyundai Kona. Second generation platforms such as the Hyundai Ioniq 5 use dedicated EV platforms. These offer improved interior space, larger battery capacities and RWD/AWD motor configurations.

Why dedicated design is good

Dedicated EV platforms design the chassis around the battery pack. Doing this enhances weight distribution helping to improve handling. It also allows for better use of interior space. Because electric vehicles only need small motors connected directly to each axle, removing the drivetrain opens things up. Benefits can include a front trunk, more room in the rear seat footwell (hello middle seat legroom!) and sizeable underfloor storage behind the rear wheels.
Dedicated design EV Buyers Guide

We’re big fans of EVs built on dedicated platforms. While they can come at a higher cost, they generally offer better performance, space and handling dynamics than EVs from a shared platform.

6. V2X Support aka ‘Battery on Wheels’

V2X encompasses a range of acronyms that describe accessing the energy stored in your EV’s battery. These include V2L (Vehicle to Load), V2H (Vehicle to Home) and V2G (Vehicle to Grid). V2X has been mostly limited to the Nissan Leaf and Mitsubishi Outlander PHEV. That’s because these vehicles are compatible with Chademo, a bi-directional charging/discharging standard.

V2H and V2G – access your EV battery

In Australia, local V2G trials have commenced. The goal is to certify V2G hardware to enable discharging energy from a Nissan Leaf’s battery into the grid [add a reference here]. The hardware has a price tag of over $10,000. However, it does promise the ability to access a massive battery. In the case of the Nissan Leaf – up to 40kWh.

We’re quite not there yet with the regulations. Powering household appliances (V2H) or exporting to the grid (V2G) from an EV still requires updates to the Australian Standard (AS4077).

V2L – campers special

In V2L standard enables appliances to be plugged into an EV, usually with a small adaptor. This means you can run anything from a microwave, kettle or jumping castle off the vehicles battery pack.
The Nissan Leaf and Mitsubishi Outlander PHEV Vehicles support Vehicle to Load (V2L). Both use lower-cost Chademo bi-directional equipment to power appliances. And more EV models that offer V2L are on the way. Scheduled local launches in 2022 include the Hyundai Ioniq 5, new Kia EV6, MG ZS EV and BYD EA1.

Ironically, both the Leaf and Outlander PHEV are renowned for having battery degradation issues – I know from experience, as I’ve owned both!. So if you are looking at either of these vehicles for V2X, I’d recommend doing your research around battery warranty, battery degradation and thermal management before taking the plunge on a V2X bidirectional charger.

7. Over-The-Air (OTA) Updates

Many EVs include 3G/4G/5g/WiFi connectivity. This connectivity enables manufacturers to update vehicle software over the air (OTA). New features, performance upgrades and bug fixes can be added remotely by the carmaker. These upgrades help to make the vehicle even better than when you bought it.

Having owned vehicles with and without OTA updates, my experience is that OTA is valuable. Whenever a new feature gets added, it brings a smile. OTA also minimises trips to dealers for upgrades or adjustments. There’s not much need to visit the mechanic as electric vehicles require less frequent maintenance. Say goodbye to spark plugs and oil filters.

8. Remote Access

Many EVs offer mobile connectivity. Accessing information and features via a mobile app can be very convenient. For example, remote access is handy when travelling and using fast chargers. You can see when charging is complete or adjust charging limits. Remote access via a mobile app can also ensure perfect driver comfort before you open the door. Activating heating and cooling, demisters, or heated and ventilated seats makes it a pleasure to get inside.

9. Battery management (heating/cooling, charging optimisation)

Good battery management is critical for safe and efficient vehicle operation — these systems control voltage limits and temperature to support maximum battery life. Battery management systems (BMS) impact the ownership experience.

The most sophisticated battery management systems (BMS) can optimise battery temperature to support higher fast charging rates and sustained power outputs.

Battery Watchouts

Less sophisticated battery management systems rely on passive or air-only cooling. So when battery temperatures become too hot or cold, the result is power output or charging limits. Batteries in older vehicles such as the Nissan Leaf Gen 1 and 2 were prone to issues. And there’s still some newer vehicles, like the Hyundai Ioniq 5, with limitations. 

If you live in a hot (over 35C) or a cold climate (under 0C), you’ll want to confirm if there are any reported issues for vehicles on your shortlist. Check online reviews or owner forums to find if temperature extremes are a potential problem for the battery.

Battery-Storage requires controlled temperature

10. Battery warranty

At one time, battery failures and degradation issues were common in early EVs (such as the Nissan Leaf Gen 1 and early Tesla Model S 2012-14). However, as EV manufacturers have improved battery quality and management, warranty claims are becoming increasingly rare events. Now battery warranties are typically around eight years/160,000km and cover faults and replacement. Some even guarantee minimum battery capacity at a prescribed level (e.g. 70% of original capacity) after eight years. 

Whether you are thinking of long-term ownership or future resale value, battery warranties are well worth factoring in. Check the length and coverage of these warranties to ensure peace of mind.

11. Purchase Incentives

In 2021, Australian governments have begun actively supporting the uptake of electric vehicles. There is now a range of financial incentives on offer. These incentives to buy an EV include upfront purchase rebates, lower or no stamp duty, transit lane privileges etc. It’s worth noting that many of the rebates are limited to a set number of vehicles each year. To avoid missing out on these rebates, check the conditions and consider the timing of your purchase.

Incentives won’t necessarily help you choose one EV over another. However, they could well help you afford a more capable car than would otherwise be the case.

The table below outlines the financial incentives available in each state and territory for passenger EVs:
