Control Of Battery Specific To Hybrid Operation Patents (Class 180/65.29)
  • Publication number: 20110089905
    Abstract: When a remaining capacity estimated by a calculator 13 is higher than a control upper limit, a charge-disabled mode is selected in that charging operation is disabled. When lower than a control lower limit lower than the control upper limit, a discharge-disabled mode is selected in that discharging operation is disabled. When higher than an upper limit of a given range having its center at a target value specified between the control upper and lower limits, an allowance mode is selected in that charging/discharging current limits are adjusted to allow a discharging amount to exceed a charging amount in a predetermined period. When not higher than the upper limit of the range, a restriction mode is selected in that charging/discharging currents are restricted so that the remaining capacity is held within the range.

    Abstract: A system for optimizing battery pack charging is provided. In this system, during charging the coupling of auxiliary systems (e.g., battery cooling systems) to the external power source are delayed so that the battery pack charge rate may be optimized, limited only by the available power. Once surplus power is available, for example as the requirements of the charging system decrease, the auxiliary system or systems may be coupled to the external power source without degrading the performance of the charging system.

    Abstract: A quick economical re-energizing system of Electric Vehicles {EV}5 intended for replacing discharged electric batteries of Electric Vehicles by charged ones, when there are no “on-boared” means for the continuous charging of batteries, and provided said EV are suitable for the offered re-energizing system, the technique of replacing the discharged batteries by charged ones, automatically {or semi-automatically}, being equivalent to the regular known re-fueling of cars, as regarding the duration of the process and the convenience of drivers and passengers, said re-energizing being enabled due to unique capabilities deriving from a newly invented electric automotive system, like allowing all the four traveling wheels of EV to swivel about their steering axes, at 90 degrees from the travel direction, or like self-elevating and lowering the EVs body in relation to the traveling wheels, as required for the offered re-energizing process of Electric Vehicles.

  • Patent number: 7880442
    Abstract: One of first through fourth target state of charge levels, which are set at values that increase gradually over time, is selected on the basis of an ON/OFF state of a specific current consumer installed in the vehicle and a state of charge immediately preceding an engine stoppage. A target state of charge is set on the basis of the selected target state of charge level and an elapsed time after the lead storage battery is installed in the vehicle, whereupon the target state of charge is compared with the actual state of charge of the lead storage battery. The lead storage battery is charged in accordance with the comparative result.

  • Publication number: 20110022222
    Abstract: A charge instructing device installed in a space such as an indoor space in which the security is ensured reads key information (ID) stored in a vehicle key held in a key holding unit and transmits the read ID to an electric powered vehicle. Electric powered vehicle performs authentication by checking the ID transmitted from charge instructing device against registration information stored in advance. The result of the authentication is then transmitted from electric powered vehicle to charge instructing device. Charge instructing device permits a charger to charge electric powered vehicle according to the result of the authentication transmitted from electric powered vehicle.

  • Publication number: 20110012553
    Abstract: A method for charging a hybrid electric vehicle having a high voltage battery that both propels the vehicle and starts the vehicle. More specifically, if the high voltage battery has a depleted or diminished charge and is unable to start an internal combustion engine, then the method described herein may be used to charge the high voltage battery with energy from a low voltage external power source. In one embodiment, the low voltage external power source is a conventional car battery that is connected to the hybrid electric vehicle by way of jumper cables.

  • Publication number: 20110006776
    Abstract: The present teachings are directed toward a machine implemented method for estimating the solid phase potentials of either positive or negative electrode of a battery. The machine implemented method includes providing battery voltage information and an estimated solid phase potential to a model coefficient updater to update a model coefficient. Battery current information is provided to a battery internal variable estimator along with the updated model coefficient so that the solid phase potentials can be determined. A multi-layer model can be utilized to determine the ion density of the electrodes. The method can be implemented on a processing device, and is particularly applicable to Li-ion batteries.
