Bonding connector with fuse section and battery module with insulative P-group separator
An embodiment is directed to a contact plate configured to establish electrical bonds between battery cells in a battery module, including at least one primary conductive layer, and a set of bonding connectors that are configured to provide direct electrical bonds between the contact plate and terminals of a group of battery cells, the set of bonding connectors being configured to connect the group of battery cells in parallel with each other, wherein at least one bonding connector in the set of bonding connectors is configured with a higher fuse rating than each other bonding connector in the set of bonding connectors so as to contain arcs among the set of bonding connectors to the at least one bonding connector.
1. A contact plate configured to establish electrical bonds between battery cells in a battery module, comprising:
a busbar; and
a set of bonding connectors configured to provide electrical bonds between the busbar and terminals of a group of battery cells, the set of bonding connectors being configured to connect the group of battery cells in parallel with each other,
wherein at least one bonding connector includes a fuse section that has a different resistance relative to a remainder of the respective bonding connector so as to contain a break in the respective bonding connector to the fuse section, and
wherein the at least one bonding connector is configured with a higher fuse rating than each other bonding connector in the set of bonding connectors so as to contain arcs among the set of bonding connectors to the at least one bonding connector.
2. The contact plate of claim 1 , wherein the busbar comprises at least one primary conductive layer.
3. The contact plate of claim 1 , wherein the set of bonding connectors is configured to provide direct electrical bonds between the busbar and terminals of a group of battery cells.
4. The contact plate of claim 1 , wherein the at least one bonding connector includes:
a lower resistance section that has a lower resistance relative to a remainder of the at least one bonding connector.
5. The contact plate of claim 4 , wherein the lower resistance section of the at least one bonding connector is thinner or narrower than one or more other sections of the at least one bonding connector.
6. The contact plate of claim 1 ,
wherein the contact plate is configured as a multi-layer contact plate that includes:
at least one primary conductive layer,
a cell terminal connection layer that is joined with the at least one primary conductive layer,
wherein the set of bonding connectors is formed from the cell terminal connection layer.
7. The contact plate of claim 1 , wherein one or more arc protection mechanisms are configured in proximity to the at least one bonding connector.
8. The contact plate of claim 1 , wherein at least one other bonding connector among the set of bonding connectors is not configured with the fuse section.
9. The contact plate of claim 1 , further comprising:
another set of bonding connectors configured to provide electrical bonds between the busbar and terminals of another group of battery cells, the another set of bonding connectors being configured to connect the another group of battery cells in parallel with each other, and to connect the group of battery cells and the another group of battery cells in series with each other.
