摘要： A smart energy center for a vehicle is provided. The smart energy center includes a buck convertor configured to provide power to a first load that has a substantially constant resistance level and a boost converter configured to provide power to a second load that requires a minimum voltage level and substantially constant power level. The smart energy center also includes a buck-boost converter configured to provide power to a third load that requires a voltage level within a threshold range and an electronic fuse configured to provide power to a fourth load. The smart energy center further includes a controller configured to operate the buck convertor, the boost converter, the buck-boost converter, and the electronic fuse.

摘要： A system in a vehicle includes memory to store values obtained for a battery that supplies current to one or more loads. The values include battery state of charge. A processor obtains a measured battery current from a battery current sensor and a measured total current from a current sensor at a battery center that supplies the current directly to the one or more loads, obtain a generator current or a direct current-to-direct current (DC-DC) converter current from the measured total current and the battery current, determine a maximum available current as a sum of a maximum available battery current and either the generator current or the DC-DC converter current, and stop a supply of the current to one or more of the one or more loads based on a result of a comparison of the maximum available current with current draw by the one or more loads.

摘要： A system in a vehicle includes a first fuse connected between a power source and a load. The first fuse is an electronic fuse (eFuse) to disconnect the load from the power source via the first fuse based on opening a first fuse switch. The system also includes a second fuse connected between the power source and the load via a second fuse switch. The first fuse and the second fuse are part of a cluster of fuses. A controller opens the first fuse switch and keeps the second fuse switch closed based on the vehicle entering a key-off mode in which the vehicle is turned off.

摘要： A vehicle, an electrical system of the vehicle and a method of operating the vehicle. The electrical system includes a battery, an electrical load that draws power from the battery, a switch between the battery and the electrical load, and a processor. The processor is configured to measure a power drawn from the battery by the electrical load and open the switch to disconnect the battery from the electrical load when the power drawn by the electrical load matches a selected criterion.

摘要： A battery clamp system for a battery includes a terminal receiving portion configured to be coupled to a terminal of the battery. The battery clamp system includes an anti-rotation projection coupled to the terminal receiving portion. The anti-rotation projection is configured to be coupled to the battery. The anti-rotation projection extends along an axis that is parallel to a longitudinal axis of the battery clamp system. The battery clamp system includes a first flange coupled to the terminal receiving portion that extends along a first flange axis substantially perpendicular to the longitudinal axis. The battery clamp system includes a second flange coupled to the terminal receiving portion so as to be spaced apart from the first flange. The first flange is configured to cooperate with the second flange to couple the terminal receiving portion to the battery.

摘要： Examples described herein provide a method for predicting electrical failures within a vehicle. The method includes selectively enabling and disabling an electrical load for the vehicle. The method further includes collecting operational data about the electrical load during the selectively enabling and disabling of the electrical load. The method further includes training the model based at least in part on the operational data to predict a failure associated with the electrical load or a wiring harness associated with the electrical load.
