A system of managing charging schedules in a fleet having electric vehicles includes a command unit. The command unit has a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is adapted to define a plurality of discharge categories, including a transportation category, a transfer category and a reserve energy category. The respective battery power in the electric vehicles is proportioned by setting a respective percentage allocation for the plurality of discharge categories. The command unit is adapted to signal the electric vehicles to charge when at least one of the plurality of discharge categories falls below the respective percentage allocation. The command unit may be adapted to group the electric vehicles in respective virtual boxes based in part on their respective physical locations.

Management of charging schedules in fleet having electric vehicles

A method of operating a mobile communication system of a motor vehicle is provided for initiating a voice call with a third party. The system includes an ECU, and the ECU includes a controller and a memory storing computer code. The method includes the steps of: (a) initiating a timer; (b) operating the ECU in a first mode in which the ECU attempts to engage in a VoNR call via a first network; (c) repeating step (b) within a predetermined amount of time until the ECU successfully engages in the VoNR call; and (d) operating the ECU in a second mode to attempt to engage in a VoLTE call via a second network in response to the controller determining that the ECU in the first mode did not successfully engage in the VoNR call within a predetermined amount of time.

A system for reduction of discontinuous-receive (DRx) transmissions for a network access device (NAD) of a telematics unit of a telematics-equipped vehicle includes: the telematics unit, configured to determine whether vehicle ignition of the telematics-equipped vehicle is on or off, the telematics unit further comprising the NAD, the NAD being configured to communicate with a network entity to perform a periodic updating procedure; the network entity, configured to communicate with the NAD for performance of the periodic updating procedure. The NAD and the network entity are further configured to reduce a frequency at which the periodic updating procedure is performed for the NAD in a DRx state relative to the frequency at which the periodic updating procedure is performed for the NAD in a vehicle ignition-on state.
