As I've mentioned before I've got a pod-point 7kw charger and use the pod-point app to see how much electricity I'm using and how much it's costing me. Now, as I understand it the capacity of the battery in the plug in is 13.8Kwh and according to Autocar the useable capacity is 11Kwh (when the range is down to zero the gauge still shows about 25% battery power left, which I presume is so that the battery is never fully discharged). Keeping those figures in mind I've been a bit surprised to see on a couple of occasions that according to the pod-point app I've used over 14Kwh in charging the car. Is that actually possible-to put more electricity into the battery than its supposed capacity? I've spoken to a technician at the dealership but he couldn't throw any light on my query. Can anyone on here come up with an explanation?

Absolutely right, you would put in 14kwh. Please don’t ask me to explain it. Sadly with the price rises in electricity, if you’re paying around the 24p per kWh, it will be almost as expensive as using fuel only. Real world tests have shown the Tucson to get about 25 miles average on a full charge.

Thanks for the reply Jeff. Can you have a go at explaining please? I don't see how you can put 14+Kwh into a battery with a capacity of 13.8Kwh which has a useable capacity of approx 11Kwh. If you had a petrol tank holding 10 gallons and the pump at your local filling station said it had put 14 gallons in, you'd want an explanation wouldn't you?

I don't disagree about the real range on electric but I'm yet to work out some accurate cost figures and will let everyone know when I have. However I'm not paying 24p/Kwh and petrol has been rising sharply lately so the calculation will always vary. What hasn't helped is our gas & elec supplier going bust resulting in a 30% rise in the costs I used before buying the car. Life's a bitch and then.....
