ELECTRIC ENERGY STORAGE AND SUPPLY SYSTEM

摘要

An electric energy storage and supply system comprising a tank capable of accommodating a plurality of battery units where each battery unit comprises an electric energy reservoir having positive and negative voltage supply terminals, three or more electric contact pads on an outer surface of the battery unit, and a dynamically configurable connection unit for electrically connecting each of said positive and negative voltage supply terminals to any one or more of said electric contact pads, wherein electric energy can be drawn from the electric energy reservoir via selectively different combinations of electric contact pads. The system further comprises at least two inwardly facing tank contact pads provided on the inside of the tank for contacting electric contact pads of neighboring battery units and for delivering electrical energy from the system towards an external load.
