Our investigation found that many EVs could become almost impossible to resell because of their limited battery life.
Last night, one motoring expert said customers should be wary of buying a used electric car beyond its warranty, as after that timespan there is no easy way of measuring how much the battery will degrade before it needs replacing.
Should your petrol engine need replacing you can expect to pay around £5,000, but replace the battery on your EV outside warranty and you're looking at an eye-watering £13,000 to £40,000, depending on the make of your car, if you fit a manufacturer's new unit.
Vehicle trading website AA Cars agrees and says that nearly half of all potential second-hand EV buyers are put off because of concerns about battery life.
Weather also plays a part in how long your battery will last and EV batteries operate best at a temperature between 25-45 degrees Celsius.
'Battery degradation might also become a more important consideration in the future - as we try to be more sustainable - and perhaps be included in an MOT. So, our advice for those who might be nervous about battery life is to buy a car that is still covered by warranty.
Concerns about battery cost are not helped by a lack of transparency within the industry - with prices of a new battery not advertised.
