摘要： An electrified vehicle includes a traction battery coupled to an electric machine that provides propulsive force, an auxiliary battery, a voltage converter coupled to the traction battery and configured to convert traction battery voltage to auxiliary battery voltage, and a controller programmed to control the voltage converter to provide either a non-oscillating voltage above a first voltage threshold, or an oscillating voltage having a peak below the first voltage threshold based on a vehicle start signal and a vehicle brake pedal position signal. The controller may control the voltage converter to provide the non-oscillating voltage in response to the vehicle start signal being received while the brake pedal position signal indicates a released brake pedal, and to provide the oscillating voltage in response to the vehicle start signal being received while the brake pedal position signal indicates a depressed brake pedal.

摘要： System and method are disclosed for vehicle accessory power management. An example vehicle includes an engine configured to operate in a start-stop mode, and a power management system. The power management system is configured to receive an input requesting use of a vehicle accessory in an accessory mode, and responsive to the input, reduce an electrical load, disable the start-stop mode, and enable use of the accessory mode.

摘要： System and method are disclosed for detecting and refreshing an aged battery in a vehicle with a start-stop system. An example vehicle includes an engine configured to operate in a start-stop mode and a power management system. The power management system is configured for determining that a charge acceptance value of a battery is below a threshold, responsively disabling the start-stop mode and displaying a message via a display, refreshing the battery and enabling the start-stop mode after refreshing the battery.
