  • Publication number: 20240092225
    Abstract: An improved power-split control system for managing a load profile of a fuel cell in a fuel cell electric vehicle (FCEV) is provided. The power-split control system is operable to actively manage the power demand between the fuel cell and the battery of a FCEV to optimize the operational life of the fuel cell. The power-split control system can use information gathered solely from historical drive cycle data or from historical drive cycle data combined with look-ahead eHorizon data. The power-split control system meets a power demand by operating the powertrain in either a battery charge sustaining mode or a battery charge depletion mode. The power-split control system is also configured to control the power distribution (to the electric motor) from the fuel cell and the battery in a manner that minimizes the degradation of the fuel cell.

  • Patent number: 11926236
    Abstract: A system is provided for performing an automated power charging process for one or more electric vehicles using a processor. Included in the processor is a charge controller that calculates a capacity of a power grid system by communicating with the power grid system via a network, and a power demand level of the one or more electric vehicles to satisfy one or more mission requirements of each electric vehicle. The power demand level of the one or more electric vehicles is compared with the capacity of the power grid system. In response to the comparison, at least one charging mode is selected from an override mode and an internal combustion engine mode for performing the automated power charging process. The charge controller automatically charges the one or more electric vehicles based on the selected at least one charging mode.

  • Patent number: 11679689
    Abstract: A method for operating one or more processors to control access of a plurality of pieces of rechargeable electrical equipment, optionally including one or more electric vehicles, to one or more charging resources. An access queue is maintained for each of the charging resources. Each piece of equipment is assigned a position in an access queue when it is determined to have a state of charge (SOC) less than the first level. Each access queue is updated based on charger information such as its availability. A piece of equipment is assigned access to a charging resource when its queue position reaches a first priority position and a charging resource is available. For each piece of equipment assigned access to a charging resource, an instruction to end access to the charging resource is issued when an elapsed charging time period is equal to or greater than a break time or the SOC is greater than a second level representative of an operational charge.
