I'm thinking of getting a leaf in the UK and I'm thinking of ways to extend its range as there are few fast charging points here and anyway I don't want to fry the batteries by fast charging. I was thinking you could put a big lump of deep cycle lead acid batteries in the trunk and connect them up via the charger, but I'm wondering if the software would allow it to charge at the samre time as driving. Found Ingineer on the web with a fossil fuel generator device so presumably you have encountered this issue? I'm an electronics engineer.
