    Abstract: A method for adapting a usage level of a battery pack includes measuring cell sense data for each respective battery cell using a cell sense circuit, the cell sense data including a cell voltage, current, and temperature. The method includes processing the cell sense data, for each respective battery cell, through multiple battery state functions of a controller to generate numeric cell degradation values (CDVs). The battery state functions are calibrated relationships of the cell sense data to predetermined battery fault conditions. Thereafter, the method includes automatically adapting the usage level of the battery pack during operation of the battery pack, via the controller, based on the numeric CDVs. An electric powertrain system includes the battery pack, cell sense circuit, a rotary electric machine, and a controller configured to execute the above method.

    Abstract: A vehicle includes an engine, a battery module, an electric motor-generator unit (MGU), and a controller. The engine generates an engine torque. The battery module stores and outputs electrical energy. The MGU is in electrical communication with the battery module and is configured to generate a motor torque based, at least in part, on the electrical energy received from the battery module. The MGU generates electrical energy. The controller is in communication with at least one powertrain module. The controller is configured to receive a signal corresponding to a selected drive mode of the vehicle; adjust an account balance of a credit account as a function of the selected drive mode; and transmit a signal to at least one of the engine, the battery module, and the MGU to allow the vehicle to operate in the selected drive mode.

    Abstract: A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.

    Abstract: A method of controlling temperature of a coolant supplied to a battery pack includes detecting a request for charging the battery pack, and commanding, via the electronic controller, a rate of charge of the battery pack. The method also includes determining the dew point inside the battery pack during the charging. The method additionally includes commanding a supply of coolant to the battery pack while the battery pack is charging. The method also includes regulating a temperature of the coolant to maintain the battery pack above the determined dew point during the charging. The method may further include maximizing the rate of charge at the regulated temperature of the coolant. A battery system employing an electronic controller configured to perform such a method, and a motor vehicle using such a battery system are also within the scope of the present disclosure.
