Abstract: A method of operating a motor vehicle includes a vehicle controller receiving, from a first feedback sensor of an HV component, a first feedback signal indicative of an electrical characteristic of the HV component, and then detecting an HV system fault if the first feedback signal is less than a predefined electrical threshold. Upon detecting the system fault, the controller commands the HV component to operate at a commanded set-point; after sending the command, the controller receives, from a second feedback sensor of the HV component, a second feedback signal indicative of an operating characteristic of the HV component. An HV pathway failure is detected if the second feedback signal is not equal to or within a predefined operating range of the commanded set-point. Upon detecting the pathway failure in an HV electrical pathway of the HV component, the vehicle controller transmits a command signal to take a remedial action.

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 system for emissions mitigation for a hybrid automobile vehicle includes an automobile vehicle provided with motive power from: a battery pack; an engine; and a controller in communication with the battery pack and the engine. A threshold battery pack state-of-charge (SOC) is predetermined. A minimum battery pack SOC is less than the threshold battery pack SOC. An engine-on charge depletion (EOCD) command is issued by the controller to start the engine in an engine-catalyst light-off operation condition when the vehicle is operating using power from the battery pack and when the threshold battery pack state-of-charge (SOC) is reached to mitigate against exceeding vehicle emissions standards.

Abstract: A system for, and method of, providing e-assist on a route. A determination may be made of whether terrain data for the route is available. A rider effort level may be determined. The terrain data may be read when available. Whether a change in slope has occurred, or is anticipated to occur, corresponding to a need for an additional input to the rider effort level may be determined. The e-assist level may be adjusted to provide a level that offsets the need for the additional input, or the rider may be informed to provide an increased effort level.

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.
