Mobility Scooter 24 volt charger from 12 volt car

Can anyone give me a cct diagram to make a 24volt charger to plug into my car cigar lighter socket please. I carry my mobilty scooter in my car and it is very difficult to keep taking it out, or taking the battery pack off to bring it into the house to charge it so it would be a great boon to me if I could be charging this whilst drivng. I can make a pcb if I can get a cct. Grateful thanks in anticipation. Tony

I'm not sure this will be of any help, but I have a powered wheelchair that runs 2 12volt battery's to give 24 volts, I designed and use this circuit to charge it 'on the go' Hope it helps. Ruaidhri
