Abstract
A battery module includes a housing, a plurality of battery cells disposed in the housing, and a printed circuit board (PCB) assembly disposed in the housing. The PCB assembly includes a PCB and a shunt disposed across a first surface of the PCB. A second surface of the shunt directly contacts the first surface of the PCB, and the shunt is electrically coupled between the battery cells and a terminal of the battery module.
Claims20
A battery module, comprising:
- a housing;
- a plurality of battery cells disposed in the housing;
- and
- a printed circuit board (PCB) assembly disposed in the housing, the PCB assembly comprising:
- a PCB;
- and
- a shunt disposed across a first surface of the PCB, wherein a second surface of the shunt directly contacts the first surface of the PCB, and wherein the shunt is electrically coupled between the plurality of battery cells and a terminal of the battery module.

A method, comprising:
- enabling an electric current to flow from a plurality of battery cells in a battery module to an output terminal of the battery module via a shunt of a printed circuit board (PCB) assembly in the battery module, wherein a bottom surface of the shunt directly contacts a top surface of a PCB of the PCB assembly, wherein the bottom surface of the shunt directly contacts an electrical connection of the PCB exposed through the top surface of the PCB;
- receiving a signal indicative of the electric current flowing through the shunt at a measurement device of the PCB via the electrical connection;
- and
- measuring characteristics of the battery module based on the signal received via the measurement device.
1 more element
A method of manufacturing a battery module, the method comprising:
- disposing a printed circuit board (PCB) on top of a lid of the battery module;
- disposing a shunt on top of and directly against the PCB;
- coupling the shunt to a bus bar on a first end of the shunt and to a connector on a second end of the shunt opposite the first end, wherein the connector is coupled to an output terminal of the battery module;
- coupling the bus bar to a terminal of a battery cell of the battery module;
- coupling a bottom surface of the shunt with electrical connectors exposed on a top surface of the PCB;
- and
- restraining the shunt on top of the PCB via a shunt clip extending upwardly from the lid and over the shunt, wherein the shunt clip comprises an extension configured to exert a downward force against a top surface of the shunt.
