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.
