Abstract: An intelligent charge limit for high voltage battery charging provides increased e-motor regeneration and reduced application of the foundation brake system of an electric vehicle. A plurality of data factors are used to calculate a maximum charge percentage. The maximum charge percentage is used to ensure there is enough charging capacity in a battery to store electrical current generated by an e-motor during downhill travel. The intelligent charge limit also provides an operator of the electric vehicle, the option of changing the charge limit to ensure that the battery receives the maximum electrical current generated by an e-motor, during downhill travel. The operator may also double plug a charging gun to eliminate a state of charge routine from considering offsetting the operator charging percentage by the plurality of data factors.

Abstract: The Method and Arrangement for Predicting Engine Out Nitrogen Oxides (EONOx) includes training multiple candidate Artificial Neural Network (ANN) architectures using training data, and then selecting an ANN architecture from the candidates using an automated ANN architecture selection algorithm and testing data.

The system is deployed into the engine controller. The training and testing sets of data include input variables from engine sensors and/or actuators that relate to EONOx, and may be acquired by testing a target engine. Selecting the optimal ANN architecture may be based on Root Mean Squared Error (RMSE) analysis using the automated ANN architecture algorithm and the training set of data.
