Patent ID: 8852481

Claim:
A method, comprising: placing an electrical energy accumulation component between two parts of a mold, said electrical energy accumulation component having two opposite and parallel main faces, a peripheral edge, a first electrical contact in a first electrical energy accumulation component corner and a second electrical contact in a second electrical energy accumulation component corner, at least one main face having at least one electrical contact zone, said mold comprising an injection chamber delimited between the two parts of the mold, said electrical energy accumulation component extending in the injection chamber at a distance from walls of the injection chamber, wherein a portion of the electrical energy accumulation element, adjacent to the peripheral edge, is held in a centering space formed between said two parts of the mold and at least partially covering said electrical contact zone, said two parts of the mold further comprising opposite positioning studs protruding into said injection chamber and bearing on said main faces of the electrical energy accumulation component; injecting an encapsulation material into said injection chamber; hardening said injected encapsulation material to form an encapsulation block overmolded on the electrical energy accumulation component except to reveal said first and second electrical contacts; and removing the encapsulated electrical energy accumulation component from the mold.
