The importance of using apps like zap map is that when you go looking for chargers, you can see the prices. Whilst that won’t help you know how much the end cost will be you can find one near you that is the most reasonably priced. For example, the nearest 2 spots to where I live are at 75p per killowatt. However, the next nearest is at 56p and I have to drive directly past the other to get there. Without that knowledge I’d be stopped in McDonalds car park paying nearly 20p per unit more, which could end up costing me £8 per charge extra.
I understand when numbers can be a daunting prospect, especially when something as simple as driving a car becomes an exercise in mathematics and physics. it’s like looking around the local petrol stations just to find the cheapest, you’ll get to know quite quickly but it’s always worth checking it all out.
