Abstract: An approach module determines that a wireless power transfer (WPT) secondary pad on a vehicle approaching a WPT primary pad is within an approach distance threshold from the WPT primary pad. A pulse module generates an electrical alignment pulse in the WPT primary pad or WPT secondary pad in response to determining that the WPT secondary pad is within the approach distance. A measurement module determines an amount of magnetic coupling between the WPT primary pad and the WPT secondary pad, and a feedback module that provides an alignment signal to a driver of the vehicle. The alignment signal represents magnetic coupling. The pulse module continues to provide electrical alignment pulses, the measurement module continues to determine an amount of magnetic coupling in response to the electrical alignment pulses, and the feedback module continues to provide alignment signals indicative of an amount of magnetic coupling as the vehicle moves in relation to the WPT primary pad.

Abstract: An automatic estimation procedure for estimating a battery's state-of-charge includes predicting the state-of-charge using a state model that includes a state-transition matrix. An observation model then uses an observability matrix in connection with predicting a measured value of a parameter. State noise, the covariance of which is characterized by a state-noise covariance matrix contaminates this prediction. Similarly, measurement noise, the covariance of which is characterized by a measurement covariance matrix, contaminates this prediction. The values of these covariance matrices are then adjusted during the estimation procedure.
