Abstract:
An electrical energy storage device, comprising:a) a casing housing an anode and a cathode in electrochemical association with each other; b) a protective housing mounted on the casing, wherein the protective housing comprises a base with an aperture therethrough for receiving a terminal pin electrically connected to one of the anode and the cathode, a projecting shoulder extending from the base to a first distance from the base, and a retaining clip extending from the base to a second distance from the base, the second distance being greater than the first distance; c) a circuit board supported on the base of the protective housing and comprising a first lead electrically connected to the terminal pin; d) a terminal cap captured between the projecting shoulder and the retaining clip to close the protective housing with the circuit board housed therein; e) a first ledge provided at a periphery of the protective housing base; f) a surrounding member having an inner wall and an outer wall, wherein the inner wall of the surrounding member captures an outer wall of the protective housing; and g) a polymeric material securing the outer wall of the surrounding member to the cell casing.
