The main claim the company is making is that they have Supercapacitor based batteries in testing. Possibly made of graphene, and in sizes of 1KW to 3KW.

If it can be independently verified, then it is ground braking result, because they seem to have achieved very high volumetric energy density, comparable to lithium ion batteries.

And being supercapacitors, they can charge very fast, in 15 min.

They have not focused on passenger cars at all.
