Ten ways to improve your electric car’s range

4. Conditioning the battery

One of the keys to a strong battery is correct charging, as better conditioned cells perform better and live longer. Given that the majority of journeys are short hops with frequent top-up charges when you return home, then most of the time it’s best to charge the battery to 80 percent of its capacity. Not only is this faster, it means you avoid the last 20 percent of charge that is slower and heats the cells more, potentially degrading them. When you do need the car’s full range capability, then you can charge the battery to its maximum capacity safely in the knowledge that the cells will be at their best and that the available range will be optimised.

5. Route planning

It’s not just a question of how far you go in your EV, it’s also how you get there. The more time you spend on high speed routes such as motorways and dual carriageways, the greater amount of energy you’ll need and the quicker your predicted range will tumble. Plan your route carefully, however, and you can get more kilometres for your kilowatt. Happily you won’t need to spend hours poring over your road atlas to figure out an efficient route, because most sat-navs will do it in seconds. With a little more than a few taps on a touchscreen you’ll find an option for the most economical route. Sure it’ll take a bit longer from A to B, but it’s also possible that reduced energy use might mean you’ll go further on a charge and not have to stop off for a time-consuming top-up.

6. Speed

The faster you go, the more energy you use - that’s just physics. This is true of all cars, regardless of power source, but it’s especially so for electric cars. Instant torque and an ability to spin at tens of thousands of revs means that almost all electric cars only have a single ratio in their gearbox (the exceptions being the Porsche Taycan and Dual Drive Teslas - the latter gears the front and rear motors differently). Single speed transmissions mean the motor works harder the faster you go, with quicker motorway speeds taking a particular toll on battery range (power consumption jumps by about a quarter between 50 and 70mph). Keep the speed down and you’ll make the electricity last longer. The same is true of acceleration, and while it's tempting to indulge in the quick off-the-line blasts that EVs are capable of, a more gentle approach to gathering speed will use a lot less energy and so keep you rolling for longer.

7. Keep it smooth

Taking the path of least resistance is always going to reap rewards when you’re looking to maximise energy use. Avoid the temptation to revel in both lead-footed acceleration and demon late-braking and you’ll not see miles drop from your range indication faster than they roll under your wheels. By honing your anticipation and concentrating on reading the road ahead you’ll be able to carry more speed everywhere - through the corners, over roundabouts and out of junctions. This will mean you can take a gentler approach to the throttle and brakes, helping rinse some extra miles for the range. More importantly, you’ll become a better and safer driver in the process, while also having more fun as you aim to keep up the average speeds without taking a heavy toll on the battery.

8. Energy use

It’s not just the electric motor that has an effect on an EV’s range - there are also all the car’s ancillary functions, such as heating, lighting and infotainment. These systems have a surprising effect on battery life, and if you set the heater to maximum in many electric cars, you’ll instantly see a couple of miles drop off the range indicator. So it's important to make sure you’re managing these energy drains as efficiently as possible. Pre-conditioning the car helps, but once moving set the climate control to its ‘eco’ setting, which normally disengages the air-con compressor. Most EVs also have heated seats, which will keep you warm while using fewer amps than the heater.
