Abstract:
A printed circuit board (PCB) assembly includes a PCB and a high current interconnect mounted on the PCB. The high current interconnect is configured to electrically couple a first high current bladed component, a second high current bladed component, and a trace disposed on the PCB. The high current interconnect includes feet made of a conductive material that are coupled to the PCB. The trace is coupled to the feet via a weld.
Abstract:
An automotive battery system that includes a lead-acid battery electrically coupled to a first bus, in which the lead-acid battery supplies electrical power to a starter via the first bus to cold crank an internal combustion engine of a vehicle; a lithium-ion battery electrically coupled to a second bus, in which the lithium-ion battery captures and stores electrical energy generated by a regenerative braking system when the vehicle brakes and supplies electrical power to the second bus using the electrical energy captured from the regenerative braking system such that a first portion of the second electrical power is supplied to an electrical system; and a DC/DC converter electrically coupled between the first bus and the second bus, in which the DC/DC converter controls supply of a second portion of the second electrical power to charge the lead-acid battery.

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.
Abstract:
The present subject matter relates to a battery module for use in a vehicle. The battery module may include a housing, a plurality of battery cells disposed within the housing, and solid state pre-charge control circuitry that pre-charges a direct current (DC) bus that may be coupled between the battery module and an electronic component of the vehicle. Furthermore, the solid state pre-charge control circuitry may include solid state electronic components as well as passive electronic components.
