Abstract:
A printed circuit board (PCB) assembly 58 may include a PCB 136 and a high current interconnect 140 mounted on the PCB 136. The high current interconnect 140 may be configured to electrically couple a first high current bladed component 153, a second high current bladed component 154, and a trace disposed on the PCB 136. The high current interconnect 140 may include feet 145 made of a conductive material that are coupled to the PCB 136. The trace may be coupled to the feet 148 via a weld.
Abstract:
The present disclosure includes an automotive battery system that uses switching devices to increase operational performance and reliability. The battery system includes a battery cell, a primary switching device electrically coupled to a terminal of the battery cell, and a secondary switching device electrically coupled to the terminal of the battery cell and in parallel with the primary switching device. The primary switching device includes an electromechanical switching device that enables charging or discharging of the battery and generates a boosted voltage. A secondary switching device includes a solid-state switching device and a diode, electrically coupled in series, which detect short circuit conditions in a power-efficient manner and remove the short circuit condition by using the boosted voltage to actuate the armature. Furthermore, parallel switching devices work together to deliver appropriate amounts of power as required by an electrical device, increasing the performance, reliability, and life-span of a battery system.
Abstract:
The present subject matter relates to a battery module 22 for use in a vehicle 10. The battery module 22 may include a housing 50, a plurality of battery cells 54 disposed within the housing 50, and solid state pre-charge control circuitry 159 that pre-charges a direct current (DC) bus 160 that may be coupled between the battery module 22 and an electronic component 161 of the vehicle 10. Furthermore, the solid state pre-charge control circuitry 159 may include solid state electronic components as well as passive electronic components.
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.
