NOVELTY - The connector has a pair of cantilevered arms placed in spaced relation to each other and extending from a base portion defining an edge portion. The cantilevered arms are splayed away from each other with distance from the base portion. A bridge links the cantilevered arms at a base of each cantilevered arm and supports the arms in spaced relation to each other at the edge portion of the base portion, where the base portion and the bridge together define a U-shape in a plane that is transverse to a major longitudinal axis of the cantilevered arms.    USE - Battery cell connector for use in an interconnect board for connecting a set of battery cells of secondary or rechargeable batteries e.g. lithium-ion batteries, nickel cadmium batteries, nickel-metal hydride batteries and lead acid batteries, in a battery block system and a modular battery system (all claimed) of computers and electric vehicles.    ADVANTAGE - The cantilevered arms can provide electrical contact between the battery cells without requiring a permanent or semi-permanent mechanical connection through soldering, bonding or permanent mechanical fastening, thus enabling the battery cells to be easily assembled and separated. The connector is easily fabricated from a single continuous piece of metal, thus eliminating electrical resistance inherent in interfaces between conductors while keeping efficient utilization of space/volume and weight and minimizing lowering energy density of batteries. The connector facilitates convenient assembly of multiple batteries, blocks of batteries and battery modules that enable monitoring subunits of the battery systems and individual blocks or modules of the battery system so as to ensure simplified removal and replacement of blocks and modules as necessary when monitoring indicates that battery replacement is necessary.    DETAILED DESCRIPTION - The connector is made of single and continuous electrically-conductive material. An INDEPENDENT CLAIM is also included for a battery block system.    DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a single battery block of eight battery cells that are connected in parallel by bus-bars on ends of the battery cells.
