Appl. No.:

17/781444

Inventors:

- Wauwatosa WI, US
Jacob Schmalz - Milwaukee WI, US
Michael Marshall - Wauwatosa WI, US
Jim Busse - Kenosha WI, US

Assignee:

BRIGGS & STRATTON, LLC - Wauwatosa WI

International Classification:

H01M 10/42
H01M 10/48
H01M 10/0525
H01M 50/213

Abstract:

A battery pack includes a battery housing, a positive terminal, a negative terminal, a plurality of cell module assemblies, and a battery management system. The plurality of cell module assemblies are received within an internal cavity of the battery housing, and include a plurality of lithium-ion battery cells that are connected in parallel. The battery management system is in communication with at least one of the plurality of cell module assemblies within the internal cavity, and is structured to receive a voltage tap measurement from each of the plurality of cell module assemblies within the internal cavity, compare the voltage tap measurement from each of the plurality of cell module assemblies to an expected voltage tap measurement, and determine if a voltage tap measurement for a cell module assembly within the plurality of cell module assemblies deviates from the expected voltage tap measurement to identify a faulty cell module assembly.

Abstract:

A battery pack includes a housing, a positive terminal and a negative terminal, and a plurality of cell module assemblies. The positive terminal and negative terminal are each externally accessible from the housing and extend into a first compartment of the housing. The cell module assemblies are received in a second compartment of the housing, and are coupled to the positive terminal and the negative terminal through a connection extending from the second compartment into the first compartment. The first compartment is accessible through a first panel that is movably coupled to the housing through a first securing mechanism providing a first level of access. The second compartment is accessible through a second panel that is movably coupled to the housing through a second securing mechanism providing a second level of access.
