Buy an electric car

Lower your emissions and save money by buying an electric car

The technology to build purely electric vehicles (EVs) has been around for more than a century, but it’s taken until now for them to become a genuine alternative to petrol or diesel cars.

A large part of this is due to legislation designed to improve inner city air quality and reduce CO2 emissions, both of which EVs are brilliant at doing. That’s because rather than using a petrol or diesel engine, which emits exhaust emissions, a fully electric car draws its power from a large rechargeable battery, using one or more motors to drive the wheels.

The benefits of such a system are not only environmental. For example, whereas a petrol or diesel engine needs to build revs to deliver maximum performance, an electric motor delivers its full power from a standstill making it very responsive. They are also almost silent in operation, which can make for a very relaxing driving experience, plus there are no gears to worry about.

Realistic electric car battery range

As battery technology improves so too does range - that is, the distance an EV can travel before it needs recharging. At the top end of the market a Tesla Model S can cover more than 300 miles from a single charge, while at the more mainstream level a Nissan Leaf or Renault Zoe Z.E. 40 will manage 150 miles without a problem. Other models, such as the BMW i3, Volkswagen e-Golf and Kia Soul EV can cover around 100-120 miles between charges.

How to charge an electric car

In theory charging an EV is simple: you just plug it into a socket and let the car do the rest. However, in reality there are several different ways to charge, from a conventional three-pin plug to a dedicated rapid charger, so it’s worth researching charging point availability in your local area. 

The time taken and cost of charging varies depending not only on the charger itself, but who provides the facilities and electricity, and also what kind of EV you have. For example, the Tesla Supercharging network is only compatible with Tesla’s own products.

Range extender electric cars

As well as fully electric cars, you might come across a piece of technology called a range extender. This is a small onboard petrol engine that can kick in to charge a battery before it goes flat.

Examples of range extender vehicles include the BMW i3 REX (above), which has an engine that can provie around 80 miles of extra battery charge, as well as the now-discontinued Vauxhall Ampera. Bith of these cars provide a little extra reassurance for anybody who worries an EV will leave them stranded with a flat battery. In reality, however, most EV owners soon get used to plugging in at convenient times, making the extra cost and complication of a range extender unnecessary.

Battery hire for electric car 

To combat consumer uncertainty over battery life and replacement costs some manufacturers, including Renault, offer the option of hiring the battery rather than owning it outright. Do so and the battery is replaced as part of the hire agreement should it go wrong. 

An additional benefit of battery hire is that it makes the outright purchase price of the car much lower. However, when you factor in that battery hire ranges from £49 to £110 per month, the costs do start to add up, particularly as there are also mileage limits to adhered to. 

Combine this with the knowledge that EV batteries are generally proving to last the lifetime of the car, and it means battery hire won’t be for everybody.

  

Buying an electric car: the good

  • Generous plug-in car grants
  • Low running costs
  • Congestion charge exempt

Buying an electric car: the not-so-good

  • Range still limited compared with petrol or diesel
  • Requires a fundamental shift in the user’s motoring routine
  • Charging infrastructure still growing
