Abstract: Methods and systems for managing operation of a battery pack are described. The methods and systems may be applied to fully electric or hybrid vehicles. The methods and systems may open a circuit within a battery in response to an indication of degradation of the battery. In addition, the methods and systems may open a contactor of the battery that controls current flow out of and into the battery.

Abstract: Dead reckoning correction utilizing patterned light projection is provided herein. An example method can include navigating a drone along a pattern using dead reckoning, the pattern having a plurality of lines, detecting one of the plurality of lines using an optical sensor of the drone, determining when a line of travel of the drone is not aligned with the one of the plurality of lines, and realigning the line of travel of the drone so as to be aligned with the one of the plurality of lines to compensate for drift that occurs during navigation using dead reckoning.

Abstract: A stabilized electric distribution system for use in a vehicle having electric assist. The system electrically couples an electric assist bus to an accessory load bus while protecting the first electrical bus from electric assist and regenerative braking induced voltage variations. An energy management controller selectively controls each of a electric motor/generator, a DC/DC converter, and an alternator to affect electric energy distribution within the system. Preferably, the electric energy distribution is controlled to maintain the first electrical bus voltage within a predefined voltage range.

Abstract: An inventive system lubricates an engine with oil prior to starting the engine. In one embodiment, the system includes an electric engine oil pump for lubricating the engine, a transmitter for transmitting a radio frequency signal, and a receiver for receiving the radio frequency signal and for actuating the electric engine oil pump. The oil pump is actuated when a driver uses the transmitter to remotely unlock the doors of the vehicle. In this manner, the driver passively actuates the oil pump prior to starting the engine.
