Electric vehicle range: Lexus explains

Electric vehicle range

Lexus explains… is a new series designed to explain features, technologies and user questions related to modern vehicles. Each article provides clear, jargon-free answers, helpful tips and resources, as well as Lexus products or services that can help along the way. This article aims to demystify some of the questions surrounding electric vehicle range.

Electric vehicle range: context

The range of a vehicle can be defined as the distance it can travel before its energy source is exhausted. It is important to remember that every vehicle, irrespective of how it is fuelled or powered, has a range; and it is possible to increase that range by replenishing its energy source.

Drivers should always be somewhat aware of their vehicle’s range while travelling. But the term range anxiety has become particularly associated with drivers of electric vehicles (EVs). It stems from their concern that “the battery will run out of power before the destination or a suitable charging point is reached” (Oxford Languages).

It is true that most early mass market EVs offered smaller ranges than combustion engine equivalents, and it is likely that the modest range of these vehicles prompted a degree of concern within the driver’s mind. But is it fair to remain anxious about the range of modern EVs? Or has the indicative range and fast charging times of models such as the all-new Lexus RZ put such concerns to rest?

Question: How many miles can you get from a full charge?

⦁ Probably more than you think or need on a daily basis. Given that the average commuting distance in the UK is a round trip of approximately 23 miles, an entire week’s worth of travel should be comfortably within the range of most modern EVs. Using that standard, the Lexus UX 300e could complete a five-day commute and still have 80 miles to spare for the weekend

⦁ Modern EVs usually offer a range of between 150-300 miles, which should fulfil the needs of both commuters and social drivers. Putting that into context, a 200-mile range is enough to get you from Bristol to Leeds, or from London to Swansea

⦁ Drivers need not feel unduly limited by the range of their EV. As discussed in our Electric Vehicle Charging article, there are almost four times as many public charging points in the UK than traditional fuel stations. So you are never far from an opportunity to top-up on route

Question: Which factors affect EV range?

Temperature. EV batteries produce power through physical and chemical reactions, and the efficiencies of these reactions are negatively affected by cold weather. This results in reduced battery capacity and, in turn, a lower range

Speed. It takes more effort for an EV to reach and maintain higher speeds than it does to achieve and maintain lower speeds. This means that an EV will use proportionally more energy on the motorway than around town

Terrain. More energy is required to pull any vehicle up a hill than to coast along on the flat. However, when it comes to going downhill, EVs offer a distinct advantage over ICE cars; they actively recoup energy because the electric motors turn into generators that recharge the vehicle’s battery pack

Driving style. Smooth and gentle driving is always more efficient than an aggressive, pedal-to-the-metal driving style. Admittedly, experiencing the instant torque of an EV from a standing start can be entertaining but it will also accelerate your power consumption

Battery condition. Batteries tend to naturally deteriorate over time, which usually means that they cannot hold the same volume of charge as they did when new. Modern battery technology has reduced this effect to the point where the decline is usually imperceptible. For example, Lexus expects the new RZ’s battery to retain more than 90% of its original capacity after ten years of driving

Electric vehicle range: top tips for maximising your range

⦁ Make a conscious effort to drive as smoothly as possible, while trying to anticipate the geography of the road ahead and the movement of traffic in order to conserve your EV’s hard-earned momentum

⦁ The relationship between efficiency and speed is not linear; the energy it takes to propel a car through the air increases exponentially the faster you drive. For example, a distance that is covered at 70mph will consume around 30% more energy than the same distance covered at 50mph

⦁ Make the most of your EV’s regenerative braking system to help top-up the batteries while on the move. It’s free energy!

⦁ Battery health is optimised by trying to maintain your EV’s level of charge between 20-80% – neither empty or full. This is good practice and will condition your battery so that it can accept a full charge and deliver maximum range when needed

⦁ Plan ahead on longer journeys by using the Lexus Charging Network or Zap Map to identify public charge points that are safely within your vehicle’s range

Electric vehicle range: conclusion

While some drivers have become fixated on the issue of EV range, it must not escape our notice that all vehicles have a maximum range. We have been coordinating our mobility around this fact since the day we passed our driving test, and the methods that we can employ to maximise the range of an EV are much the same as those for any vehicle with an internal combustion engine.

Most modern EVs have sufficient range to handle 99% of the journeys we make without needing to stop and be recharged. But if you need to go the extra mile (or miles) then you can always pause at one of the 32,000+ public charging points dotted throughout the UK.

  1. I was going to purchase a EV then i was not quite swayed by the current details , most car manufacturers quote silly ranges of electric cars , i know it is not possible to be exact due to human,s driving conditions but surely they can be a lot more exact than what they say .I purchased a NX300H and i am a careful driver using the EV mode whenever possible and i have calculated that a i have a return of 38 miles to the gallon which is a lower than i thought i would get considering the promotional figures .

    1. Hello Russell,
      Thanks for your comment.
      The official fuel consumption figures for the NX 300h range from 36.6 – 39.7 mpg.
      This means that you are achieving the official test figures with your vehicle.

  2. I own a 2002 Lexus 430. Yes that’s a 4.3 litre V8 which has covered 103,000 miles in it’s entire life and still runs like a dream, achieving 30-35 MPG on open roads.
    Why should I scrap a perfectly sound and very luxurious ICE vehicle for the dubious virtues of a battery?
    What is the carbon footprint of the production of a new EV including the battery?
    Thanks and regards from a very satisfied Lexus owner.

    1. Hello,
      Thanks for your commitment to Lexus.
      We are glad to hear that your Lexus is still going strong.
      We wish you many more happy miles!
      Many thanks.
