Abstract: A plurality of life cycle power management modes are implemented for a vehicle. A vehicle is operated in a transport mode wherein controllers of the vehicle are configured to reduce their respective key-off loads on a battery of the vehicle, including that doors of the vehicle are unlocked and access control systems of the vehicle are unpowered. Responsive to receipt of a first request for moving the vehicle to a transport temporary normal mode, the vehicle transitions from the transport mode to the transport temporary normal mode which is another of the life cycle power management modes. In the transport temporary normal mode, the controllers of the vehicle are configured to operate in a full power state. After a predefined timeout period elapses after detecting a key-off state and/or closure of the doors of the vehicle, the vehicle returns from the transport temporary normal mode to the transport mode.

Abstract: A depletion amount of energy required to charge a user device connected to a device port of a vehicle is estimated based on a state of charge (SoC) of a device battery of the connected user device. Responsive to an expected SoC of a LV battery of the vehicle after providing the depletion amount of energy exceeding a calibrated threshold amount of energy of the LV battery, the connected user device is charged during key off. Otherwise, an engine start/stop schedule defining a time to start an engine of the vehicle and a duration of run time for the engine is utilized to generate additional energy to charge the connected user device to ensure the LV battery remains above the calibrated threshold amount of energy.

Abstract: Systems and methods for mitigating vehicle battery drain are provided. Once a vehicle determines it is no longer in use (for example, after a key-off event of the vehicle), the vehicle may monitor the state of charge (SoC) of the battery that is used to power the various electronic control units (ECUs) of the vehicle (and/or other components of the vehicle that require an electrical power source to operate). The vehicle may take action in multiple phases depending on the current SoC of the battery and/or the rate of change of the SoC. A first phase is triggered if the SoC does not satisfy a first threshold SoC and/or the rate of change of the SoC is greater than or greater than or equal to a threshold rate of change. A second phase is triggered if the SoC falls even further and does not satisfy a second threshold SoC that is lower than the first threshold SoC.

Abstract: A vehicle including a Direct Current-to-Direct Current (DC to DC) converter, a low-voltage battery, a memory and a processor is disclosed. The DC to DC converter may be configured to convert a high voltage electric power to a low voltage electric power, and the low-voltage battery may be configured to be charged by the DC to DC converter via the low voltage electric power. The memory may be configured to store inputs associated with a vehicle user. The processor may be configured to determine that a trigger event has occurred, and estimate a future vehicle usage based on the inputs responsive to determining that the trigger event has occurred. The processor may further control a charging operation of the low-voltage battery by the DC to DC converter based on the future vehicle usage.

Abstract: A first vehicle configured to jump start a second vehicle is disclosed. The first vehicle may include a first energy storage system, a second energy storage system, and a converter. The first vehicle may further include a switch between the second energy storage system and the converter, and a control unit. The control unit may obtain a user request to activate a jump start mode of the first vehicle, deactivate a vehicle load in the first vehicle, and cause the switch to operate in the ON state. The control unit may further cause the second energy storage system to supply a first amount of current to pre-charge a battery of the second vehicle for a predefined time duration, and cause the second energy storage system to supply a second amount of current to the battery to start a second vehicle ignition system when the battery is pre-charged.

Abstract: A motor vehicle electrical distribution system includes an upfitter power supply subsystem with overcurrent protection for tripping (opening) a solid-state relay when current drawn from a main electrical source by the upfitter subsystem impacts other priority electrical loads of the vehicle. Warnings/alerts are generated to inform the user (e.g., driver) of the tripping events, which may include real-time graphing of a recent history of events. In order to restore power to the upfitter subsystem, a voltage supplied by a supplemental battery (i.e., vehicle start-up battery) to the upfitter subsystem is monitored. If the voltage stabilizes then a voltage from the main electrical source is intentionally dropped to the stabilized value and the solid-state relay is re-closed. Then the main voltage is ramped back up to its nominal value. An automatic reset time may be added to delay the reclosing if the solid-state relay has been operated excessively.
