Instead of plugging the whole car into an outlet, you can pull out any of the three battery packs in the trunk and hook 'em into the wall. That means the car doesn't have to have direct access to a plug to be able to juice up, you just take the batteries to where the power's at and commence charging. They're calling the system H4V, and are powering the unit on lithium ion phosphate batteries. MIRA expects the retrofit to an existing car to cost about £2000 (around $3950 US).
