Abstract: A vehicle electrical system includes a battery, a customer connection point, a switch electrically connected in series between the battery and the customer connection point, a computer communicatively coupled to the switch, and a transceiver communicatively coupled to the computer. The computer is programmed to instruct the switch to open in response to a state of charge of the battery decreasing below a charge threshold, receive an input selecting a time limit, and instruct the transceiver to transmit a message to a remote server upon determining that the state of charge of the battery will decrease below the charge threshold in less than the time limit from a current time.

Abstract: A power system for a vehicle comprises a first power supply network configured to operate at a first voltage. The first power supply network comprises a first alternator, a starter motor, and a battery conductively connected to the first alternator and the starter motor. The system further comprises a second power supply network configured to operate at a second voltage. The second power supply network comprises a second alternator, a power supply receptacle configured to output power to an external accessory, and a capacitive energy storage device conductively connected to the second alternator and the power supply receptacle. A directional conduction device interconnects the first power supply network and the second power supply network.

Abstract: A vehicle power system includes a controller that reduces a voltage setpoint of an alternator by a predetermined amount in response to a magnitude of electric charge provided by the alternator during a predetermined time period exceeding a first threshold and a rate of change of power output by the alternator exceeding a second threshold during the time period. The controller also regulates an output voltage of the alternator based on the setpoint.

Abstract: System and method are disclosed for power management in a vehicle having two or more alternators. An example vehicle power system includes first and second alternators, and a processor. The processor is configured to determine that a load coupled to the first and second alternators increases at greater than a threshold rate. The processor is also configured to responsively (i) reduce respective voltage setpoints of the first and second alternators, and (ii) turn off the second alternator. And the processor is further configured to, after determining that a voltage transient caused by the load has expired, turn on the second alternator.

Abstract: Method and apparatus are disclosed for detecting and mitigating vehicle battery gas emission into the vehicle cabin. An example vehicle includes a battery, a vent tube coupled to the battery for venting gas outside a vehicle cabin, a gas flow sensor for determining a measured flow rate at an end of the vent tube opposite the battery, and a processor. The processor is configured for determining an expected flow rate range based on a battery characteristic, and responsive to determining that the measured flow rate is outside the expected flow rate range, initiating a protective action.

Abstract: A system includes a processor configured to receive part identification input identifying a newly installed vehicle part. The processor is also configured to transmit part identification data to a cloud server, responsive to the input and receive electronic control unit (ECU) reconfiguration instructions responsive to the transmission. The processor is further configured to execute the instructions to reconfigure a vehicle ECU identified in the instructions.
