A battery load management system and methods of managing a battery load, e.g., in a vehicle, may be directed to a converter that steps down electrical power from an input voltage to a reduced voltage. An electrical bus in electrical communication with the converter may be configured to supply electrical power received from the converter at the reduced voltage to a plurality of electrical loads. A controller may be configured to detect a load shed trigger, and in response to the detection select one or more low-priority loads included in the plurality of electrical loads. The controller may also be configured to reduce electrical power consumption by the one or more low-priority loads.

An ultra low cost electric vehicle heating apparatus, components thereof, and related method are herein described. A driver circuit operates a switching device at an intermediate state between fully-turned-off and fully-turned-on, in a high power dissipation heating mode, to efficiently produce heat energy for heating a passenger compartment, or energy storage system, of an electric vehicle. The driver circuit operates the switching device to have a fully-turned-off state and a fully-turned-on state in a main function mode for a traction inverter or an energy storage system charger of the electric vehicle. The driver circuit is operable to cycle the heating mode and the main function mode for combining such heating and such main function operation of the traction inverter, or the charger, without compromising the operation of the traction motor, or charger, while simultaneously eliminating many of the expensive resistive heating components in use by practitioners of the art.

A control system controls power supply in a vehicle. The control system includes sub-power managers and an integrated power manager. The sub-power managers control respective output power of a plurality of subsystems that actualize functions of the vehicle. The integrated power manager performs integrated control of output power in the overall vehicle by exchanging information with the plurality of sub-power managers. The information that is exchanged between the plurality of sub-power managers and the integrated power manager includes information that enables calculation of a physical quantity that is expressed by at least either of a power dimension and an energy dimension.

A controller selectively generates output for display indicative of a recommendation against use of a power outlet in a vehicle with devices external to the vehicle having a power rating greater than a predefined power rating threshold based on a difference between a current state of charge of a battery of the vehicle and a required state of charge for the battery.
