Abstract: Sleep state power consumption estimation for vehicles is provided. An electric vehicle can include an electronic control unit (ECU). The ECU can enter a sleep state responsive to the electric vehicle entering a sleep mode and enter a run state from the sleep state responsive to the electric vehicle exiting the sleep mode. The ECU can determine, based on a range loss estimation corresponding to an estimated power consumption during the sleep mode, a remaining rage estimation of the vehicle. In some implementations, the electric vehicle includes sensors, and the ECU can obtain sensor data indicating a power consumption measurement during the sleep mode of the electric vehicle, from which the remaining range estimation can be determined. In other implementations, the ECU can determine the remaining range estimation without active hardware monitoring based on a predetermined sleep state power consumption rate and a duration of the sleep mode.

Abstract: An apparatus may include a DC to DC converter that converts a high voltage level from a battery pack to a relatively lower voltage level for various components of a vehicle. The DC to DC converter may provide an alternate power supply in addition to a battery that is separate from the battery pack. The battery pack and the DC to DC converter may be used to supply power, instead of the battery, during a sleep mode of a vehicle. Further, the DC to DC converter can supply power to float charge the battery, thus minimizing cycling of the battery. The DC to DC converter and the battery may provide a redundant, or backup, power source for a vehicle.

The door system may include a driver configured to drive the door actuator to move the door, and a back EMF protection circuit. The back EMF protection circuit detects a back EMF voltage generated by the door actuator when the door is moved, and determines whether the back EMF voltage exceeds an overvoltage threshold. In response to determining that the back EMF voltage exceeds the overvoltage threshold, the back EMF protection circuit causes the driver to transition to an enabled state to short the back EMF voltage to ground.
