Abstract
This disclosure details exemplary battery pack designs for use in electrified vehicles. Exemplary battery packs may include a sense lead assembly having a circuit board that is centrally mounted between first and second wiring members (e.g., flat flexibles cables or flat printed circuits). The circuit board establishes a suitable mounting surface for incorporating sense lead fuses into the sense lead assembly. The centralized sense lead fuses provide for simple and reliable servicing of the battery array in response to battery overcurrent conditions.
Claims23
A battery array, comprising:
- a sense lead assembly including:
- a first wiring member including a first voltage sense lead;
- a circuit board connected to the first wiring member;
- and
- a first fuse mounted to the circuit board and connected to the first voltage sense lead.
A method, comprising:
- mounting a fuse to a circuit board of a sense lead assembly of a battery array circuit connection system,
- wherein the fuse is configured to break a circuit established by a voltage sense lead of the sense lead assembly in response to a battery overcurrent condition.
A battery array, comprising:
- a grouping of battery cells;
- and
- a sense lead assembly connected to the grouping of battery cells, wherein the sense lead assembly includes:
- a first wiring member including a first voltage sense lead;
- a second wiring member including a second voltage sense lead;
- a printed circuit board (PCB) connected to the first and second wiring members,
- wherein the PCB is comprised of a first material and the first and second wiring members are comprised of a second, different material;
- a first removable fuse mounted to the circuit board and connected to the first voltage sense lead at a first side of a transition area of the circuit board;
- a second removable fuse mounted to the circuit board and connected to the second voltage sense lead;
- a sense lead connector;
- a first additional wire connecting the sense lead connector to the PCB at a second side of the transition area of the circuit board;
- and
- a second additional wire connecting the sense lead connector to the PCB near the second removable fuse.
