Abstract: A system and method of determining a battery condition includes a discharge circuit determining a depth of discharge prior to charging a battery and determining an average depth of discharge over a time period. A cycle life estimation module determines a cycle life estimation based on the average depth of discharge. A state of health determination circuit determines a state of health of the battery based on the cycle life estimation. A display displays a state of health indicator.

Abstract: A system and method for controlling charging of a plurality of battery cells includes a cell voltage detector determining a top-of-charge voltage for each of the plurality of battery cells. An imbalance circuit compares the top-of-charge voltage for each of the plurality of battery cells to an imbalance threshold and determines a first battery cell of the plurality of battery cells is above the imbalance threshold by an imbalance amount. A shunt control circuit determines an imbalance shunt time for the first battery cell based on the imbalance amount and controls discharging the first battery cell for the imbalance shunt time toward the imbalance threshold.

Abstract: A method and system for operating a battery system includes storing battery charge usage data for a plurality of days in a memory, obtaining usage data for a current day based on a past corresponding day, comparing the usage data for the current day to a plurality of threshold, when the usage data is less than a first usage threshold, setting an operating state of charge range for the current to a first state of charge range, when the usage data is between the first usage threshold and a second usage threshold, setting the operating state of charge range for the current to a second state of charge range greater than the first state of charge range, when the usage data is greater than the second usage threshold, setting the operating state of charge range for the current to a third state of charge range greater the second state of charge range, and charging and discharging the battery system based on the state of charge range during the current.

Abstract: An automotive vehicle braking system includes a hydraulic brake system in communication with a regenerative brake system. The regenerative brake system has both a fixed system logic portion and a user-adjustable system logic portion. The fixed system logic of the regenerative brake system is driven by a brake member displacement.

Abstract: An automotive vehicle braking system includes an electronic shift controller in communication with a vehicle control unit for manually adjusting a signal indicative of a regenerative braking intensity. The electronic shift controller communicates with the vehicle control unit through a gateway module for analyzing the signal indicative of the regenerative braking intensity.

Abstract: In accordance with the present invention, a drive mode switch is provided that is configured to move in a rotary motion, a substantially fore-and-aft motion and a substantially cross-vehicle motion. The switch sends a signal that corresponds to each of the motions. A controller is provided that receives the signals from the switch and includes programmed software that correlates the signals to various vehicle motion outputs, such as forward and reverse.

Abstract: An automotive vehicle braking system includes a regenerative brake system operable upon a deceleration request from at least one of an acceleration member and a braking member. At least a portion of the deceleration request is adjustable by a user when the deceleration request is provided by the acceleration member.

Abstract: An automotive vehicle system includes a light and a module. The light is adapted to be attached to an exterior of a vehicle. The module selectively illuminates the light during a vehicle stationary period based on an electric drive system state of charge. The module further selectively illuminates the light during a vehicle driven period based on vehicle operating conditions different than the electric drive system state of charge.
