20120200257 | Method of Controlling a State-of-Charge (SOC) of a Vehicle Battery - A system and method for controlling a state-of-charge (SOC) of a vehicle battery, such as a high-voltage battery used by a hybrid electric vehicle (HEV) for vehicle propulsion, so that the SOC is maintained within a desired SOC range that is temperature-dependent. In an exemplary embodiment, the system and method use a battery temperature prediction to determine a desired SOC range, and then control the amount of charge on the vehicle battery such that the SOC is maintained within the desired SOC range. As the battery temperature prediction goes lower (i.e., as it gets colder), the desired SOC range may need to be adjusted or shifted upwards in order to account for increased internal battery resistance and to ensure that the vehicle battery has enough power to start the vehicle. Similarly, as the battery temperature prediction goes higher (i.e., as it gets warmer), the desired SOC range may need to be adjusted or shifted downwards in order to reduce degradation effects and improve battery. The exemplary system and method control the SOC of the vehicle battery and may seek to optimize a number of different parameters, including battery life, battery performance and/or vehicle fuel economy. | 08-09-2012 |
20120261397 | METHOD AND SYSTEM FOR HEATING A VEHICLE BATTERY - A method and system for heating a vehicle battery, such as the type used for vehicle propulsion in a hybrid electric vehicle (HEV). Depending on the battery chemistry involved, such batteries may not perform well in extremely cold environments. For instance, a lithium-ion battery can exhibit a high internal resistance when the battery is extremely cold, which in turn can negatively affect the available power or other capabilities of the battery. According to an exemplary embodiment, the method and system take advantage of the high internal resistance in a cold vehicle battery by purposely cycling electrical current in and/or out of the battery so that heat is created. This heat warms up the vehicle battery and thereby improves its overall performance and capabilities. | 10-18-2012 |
20120293317 | METHOD FOR USE WITH VEHICLE HAVING SELECTABLE TRANSFER CASE - A method for notifying, indicating or otherwise alerting a driver when it may be desirable to switch to a different transfer case mode. According to an exemplary embodiment, the method uses one or more environmental and/or vehicle conditions to evaluate a current transfer case mode and to determine if it is the most preferable or optimal mode. If the current transfer case mode is not optimal, then the method may recommend that the driver manually switch transfer case modes by notifying or alerting them through a visual and/or audio message. In one example, the method recommends a transition from a four-wheel mode to a two-wheel mode, or vice-versa, with a visual message on an instrument panel gauge. | 11-22-2012 |
20150066837 | METHOD FOR PREDICTING CHARGING PROCESS DURATION - A method for predicting the duration of a future charging process for a vehicle battery. The method comprises estimating a future charge amount of the battery corresponding to the start of the future charging process. The method further comprises estimating a future temperature of the battery. The method still further comprises determining a future charging power or a characteristic thereof to be applied to the battery during the future charging process, wherein the future charging power or characteristic thereof is based on the estimated future charge amount and the estimated future temperature and is representative of a charging amount or characteristic thereof that will maintain the temperature of the battery at or below a threshold temperature during the future charging process. The method still further comprises predicting a duration of the future charging process based on the estimated future charge amount and the determined future charging power or characteristic thereof. | 03-05-2015 |

The normalized measurement datum is subtracted from each of the measured values to determine a plurality of deviations of the corresponding points. Shades are assigned that correspond to a range of possible deviations. Each of the deviations are displayed as a data segment on a grid that represents the shape of the surface of the bearing. Each data segment is shaded on the grid to the corresponding shade to provide a topographical representation of the contours of the surface of the bearing. | 08-26-2010 |
