Abstract: A vehicle determines a first resistance of a starter motor and a starter cable connected thereto based at least in part on the first voltage of a power source. The vehicle determines a predicted minimum battery voltage based at least in part on the first resistance of the starter motor and the starter cable. The vehicle, in response to the predicted minimum battery voltage satisfying a threshold, enables a vehicle stop-start function, and, in response to the predicted minimum battery voltage failing to satisfy the threshold, disables the vehicle stop-start function.

Abstract: Method and apparatus are disclosed for a vehicle battery recharge controller based on a gassing rate. An example vehicle includes a battery with a gassing sensor and a body control module with a battery management controller. The battery management controller decreases a voltage used to charge the battery in response to a gassing rate measured by the gassing sensor satisfying a first threshold. Additionally, the battery management controller increases the voltage used to charge the battery in response to a gassing rate measured by the gassing sensor satisfying a second threshold lower than the first threshold.

Abstract: A method for allowing or prohibiting automatic engine stopping and starting is presented. In one example, an engine cranking time is predicted and compared to a threshold value to determine whether or not automatic engine stopping and starting is to be allowed or prohibited. The predicted engine cranking time is a metric for judging whether or not vehicle occupants might find a possible subsequent vehicle operation delay objectionable due to an engine starting event.
