  • Patent number: 10819136
    Abstract: A vehicle includes first loads, a power source, and a processor coupled to the power source. Each of the first loads is configured to generate a fault signal indicative of an occurrence of an action performed by said first load to mitigate a voltage transient event. The processor is configured to, in response to a second different load being electrically coupled to the power source: control a voltage available within the power source based on calibration parameters; and in response to receiving the fault signal, adjust at least one of the calibration parameters.
    Type: Grant
    Filed: February 15, 2019
    Date of Patent: October 27, 2020

  • Patent number: 10696181
    Abstract: This disclosure describes vehicle systems and methods for controlling charging of an auxiliary (i.e., low voltage) battery of an electrified vehicle. Exemplary charging methods may dynamically adjust a low voltage setpoint of a power converter during the low voltage support. The proposed systems and methods therefore achieve constrained low voltage support by controlling the power drawn by the power converter at an appropriate level during the low voltage support.

  • Patent number: 10491147
    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.

  • Patent number: 10112487
    Abstract: A system using a computer to be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination installed. One aspect includes a system, programmed to receive a fault signal from an auxiliary battery sensor. The system also determines if a low voltage set point is greater than the main battery voltage, and sends an open switch signal to a battery isolation switch if the low voltage set point is greater than the main battery voltage value. The system will send an auxiliary set point signal to an auxiliary battery charger to maintain a low voltage. The system will receive a current signal from an auxiliary battery sensor to indicate an auxiliary battery current value. The system also determines if the auxiliary battery current is above a maximum current value, and send a disable auxiliary battery maintenance signal to the auxiliary battery charger.
