    摘要： A system and method for identifying and responding to exceptional charge events of series-connected energy storage elements. An exceptional charge event detector for an energy storage system having a plurality of series-connected battery elements, comprising: a data acquisition system determining, for each battery element of the plurality of series-connected battery elements, a series of charge dependent parameters during an operational period of the energy storage system; a controller, coupled to said data acquisition system, establishing a characterization for each battery element of the plurality of series-connected battery elements from said series of charge dependent parameters; wherein said characterization includes either a normal characteristic pattern or an exceptional characteristic pattern for each time segment of a plurality of time segments spanning said operational period; and wherein said controller detects an exceptional charge event for a selected one battery element whenever said characterization for said selected one battery element includes an exceptional characteristic pattern in any particular time segment where a normal characteristic pattern is expected.

    摘要： A computer-implemented method to respond to an exceptional charge event including an overdischarge in an energy storage system having a plurality of series-connected battery elements. The method includes monitoring, using the microprocessor, the energy storage system for a charge imbalance using a first detection modality; initiating a reduction of said charge imbalance using a first response modality; monitoring, using the microprocessor, the energy storage system for the overdischarge of a particular one battery element of the plurality of battery elements using a second detection modality different from said first detection modality; and initiating a response to said exceptional charge event using a second response modality different from said first response modality, said response decreasing a risk associated with said overdischarge.

    摘要： A dual mode battery charging system and method of use are provided for use in an electric vehicle. The system utilizes at least two user selectable, charging operational modes. In a first operational mode, a state of charge circuit powers on the engine/generator system whenever the battery state of charge falls below a first level and until the battery state of charge reaches a second level, where the second level is higher than the first level. In a second operational mode, the state of charge circuit powers on the engine/generator system whenever the battery state of charge falls below a third level and until the battery state of charge reaches the second level, where the third level is lower than both the first and second levels.
