  • Patent number: 9136727
    Abstract: When warming-up of a battery is in progress (S12), a battery charge state at the warming-up start time of the battery is set to a battery hold capacity SOChold (S14, S15), and a charge power for the battery is controlled so that a battery charge state SOC is kept at SOChold. When a present time is in a timer charge reservation time (S11), the charge power for the battery is controlled so that SOC becomes a full charge state SOCfull (S17). Even if SOC has a tendency to temporarily decrease due to a rapid increase of heater consumption power just after start of warming-up of the battery, by keeping SOC at SOChold (SOC=SOChold), SOC can reach a full charge state as intended during the timer charge reservation time. A proportion of charge using low-priced midnight power is increased to a maximum then running cost can be suppressed.

  • Publication number: 20150120107
    Abstract: A driving pattern based plug-in hybrid electric vehicle (PHEV) energy consumption preplanning process enables a PHEV trip-oriented energy management control (TEMC) to utilize scalable levels of available trip foreknowledge in order to optimize the onboard energy (fuel and electricity) usage. The preplanning process generates an optimal battery state-of-charge (SOC) depletion profile for a given trip to be traveled by a PHEV. The preplanning process may generate the battery SOC profile using a driving pattern based dynamic programming (DP) algorithm. The TEMC controls the onboard energy usage in accordance with the battery SOC profile, which is optimized for the trip. The preplanning process makes use of spatial domain normalized drive power demand (SNDP) (or S-NDP) distributions in which each set of distributions is indicative of a respective driving pattern. The trip foreknowledge is used to select the driving pattern best representative of the driving process for the trip.

  • Publication number: 20150112530
    Abstract: A method and system for controlling a fuel cell vehicle are provided in which a bidirectional converter monitors a state of a fuel cell vehicle in real time to improve control responsiveness in a transient state of the fuel cell vehicle. The method includes receiving, by a bidirectional converter, a command for a current limiting value in the high voltage battery from the fuel cell controller while the fuel cell vehicle is driven. In addition, the bidirectional converter is configured to determine whether the fuel cell vehicle is switched to a predetermined mode and change the current limiting value of the high voltage battery. A predetermined control is performed by the bidirectional converter based on the changed current limiting value when the fuel cell vehicle is switched to the predetermined mode.
