Abstract
An electrical insulation system and method for electrical power storage component separation is disclosed. Some implementations of the system use various forms of polyurethane elastomer based material such as tapes to electrically separate various components of electrical power storage devices such as battery packs. These components can include cells, connecting tabs, printed circuit assemblies, solder joints, nickel strips, and other conductive members.

14. A method for manufacturing an electrical storage device having a life, the method comprising:
-
providing a first storage device component with a first electrically conducting surface portion; providing a second storage device component with a second electrically conducting surface portion, at least one of the first electrically conducting surface portion and the second electrically conducting surface portion having an unsmooth area; providing puncture resistant electrical insulating material having a durability; positioning the first storage device component, the second storage device component, and the insulating material inside the electrical storage device with the insulating material adjacent at least the unsmooth area, the durability of the insulating material being sufficient to resist forces imparted to the insulating material by the unsmooth area to maintain electrical separation between the first electrically conducting surface portion and the second electrically conducting surface portion over the life of the electrical storage device. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for manufacturing a battery pack having a life, the method comprising:
-
positioning a battery cell proximate to a circuit, the battery cell including a first portion and a first terminal, the circuit including a conductive first portion and a second portion; positioning an electrically conductive member proximate to the battery cell and the circuit, the electrically conductive member including a first portion, a second portion, and a third portion, such that the first portion of the electrically conductive member contacts the first terminal of the battery cell and the second portion of the electrically conductive member contacts the conductive first portion of the circuit; positioning first electrical insulating material between the first portion of the battery cell and the third portion of the electrically conductive member, at least one of the first portion of the battery cell and the third portion of the electrically conductive member including a first unsmooth area, the first electrical insulating material having sufficient durability to maintain electrical separation between the first portion of the battery cell and the third portion of the electrically conductive member over the life of the battery pack; and positioning second electrical insulating material between the second portion of the circuit and the third portion of the electrically conductive member, at least one of the second portion of the circuit and the third portion of the electrically conductive member having a second unsmooth area, the second electrical insulating material having sufficient durability to maintain electrical separation between the second portion of the circuit and the third portion of the electrically conductive member over the life of the battery pack. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)
