Abstract: A rechargeable battery module is disclosed in the present invention. The rechargeable battery module includes a number of rechargeable battery cells, each having identical appearance, arranged in the same direction and fixed to on another by at least one fixing element, wherein the rechargeable battery cells are linked in series and/or in parallel to store and provide power; at least one anode end conductive sheet, electrically connected to anodes of at least two rechargeable battery cells; at least one cathode end conductive sheet, electrically connected to cathodes of at least two rechargeable battery cells; and a number of silicone thermal conducting structures.

Abstract: A detachable modulized battery charging assembly for electric vehicles is disclosed. The detachable modulized battery charging assembly includes a number of charging units for charging rechargeable batteries of electric vehicles while the rechargeable batteries are detachably inserted therein; a managing unit for controlling the charging units, recording charging statuses of the rechargeable batteries, and confirming identification of a user; and a user interface unit for communicating with the user. The charging units, the managing unit and the user interface unit are modulized and can be fixed together in different arrangements.

Abstract: A battery pack having a cooling system is disclosed. The battery pack includes battery units linked in series or in parallel and arranged in a plane; thermal conducting bars each has a number of side walls and two ends, averagely located among the battery units and substantially contacted to the battery units by the side walls, for conducting heat out of the battery units to the two ends; and a housing for containing the battery units and thermal conducting bars and conducting heat from the ends of the thermal conducting bars to outside of the housing. At least one end of the thermal conducting bar is connected to the housing and becomes an internal supporting structure of the housing.
