Abstract: Methods for fast-charging batteries while minimizing lithium plating (LP) comprise charging the battery in a first phase at a near-maximum charging current, subsequently charging the battery in a second phase by decreasing the charging current while charging in order to maintain the anode potential equal to or above an anode potential threshold, and subsequently charging the battery in a third phase at constant cell potential such that the cathode potential remains below a cathode potential threshold. LP can be detected by determining the derivative of the charging current and examining the derivative for smooth curves or local discontinuities, wherein a smooth curve indicates the absence of LP and a curve with a local discontinuity indicates the presence of LP. A fast-charging profile can be defined by plotting the cell potential vs. the charging current from the first phase, the second phase, and the third phase to define a fast-charging profile.

In response to determining the evaluation time is complete, the control module compares the accumulated slip with a calibrated threshold of slip. In response to the accumulated slip being less than or equal to the calibrated threshold of slip, the control module determines the torque converter clutch is stuck in the engaged position.
