A vehicular battery pack (9) comprising:
- a support structure (11) extending along a vehicular axis (X), defining within it a housing (13);
- a three-dimensional substrate (14) disposed within the housing (13) and provided with a plurality of seats (17), each extending internally to the substrate (14) along an axis (A) longitudinally from an opening (18) of a first surface (15) external to the substrate (14);
- a plurality of active primary units (19);
- each primary unit (19) comprising at least a first electrode (20), a first separator (21), a second electrode (22) and a second separator (23), arranged alternated each other and stacked together to form a stack or wound to form a winding (24);
- each primary unit (19) comprising a first terminal (25) connected to the first electrode (20) and a second terminal (26) connected to the second electrode (22);
- wherein each primary unit (19) is entirely inserted into a respective seat (17) of the plurality of seats (17) of the substrate (14);
- wherein each seat (17) has a shape complementary to that of each primary unit (19);
- the battery pack (9) further comprising a first closure assembly (27), which closes a plurality of primary units (19) inside the respective seats (17);
- wherein the closure assembly comprises a plurality of first closure elements (28) each electrically conductive and arranged at a respective opening (18);
- wherein the first terminal (25) is electrically in contact with the respective first closure element of the respective housing (17).
Method of assembling a vehicle battery pack (9) comprising the steps of:
- providing a substrate (14) with a plurality of seats (17), each extending along a longitudinal axis (A) from an opening (18) of a first surface (15) on the outside of the substrate (14) towards the inside of the substrate (14) itself;
- providing a plurality of active primary units (19);
- each primary unit (19) comprising at least a first electrode (20), a first separator (21), a second electrode (22) and a second separator (23), arranged alternated each other and stacked together to form a stack or coiled to form a coil (24);
- each primary unit (19) comprising a first terminal (25) connected to the first electrode (20) and a second terminal (26) connected to the second electrode (22);
- inserting each primary unit (19) entirely within a respective seat (17) of the plurality of seats (17) of the substrate (14);
- wherein each seat (17) has a shape complementary to that of each primary unit (19);
- closing the plurality of seats (17) with within, each, at least one respective primary unit (19) by means of at least one first closure assembly (27), which comprises the plurality of primary units (19) within the respective seat (17);
- wherein the closure assembly comprises a plurality of electrically conductive first closure elements (28) each arranged at a respective seat (17);
- arranging, prior to or concurrently with the step of closing, the first terminal (25) electrically in contact with the respective first closure element of the respective seat (17).
