1. A method comprising:
- obtaining an ambient temperature for a vehicle having a rechargeable energy storage system (RESS);
obtaining a temperature of the RESS;
estimating an expected degradation of the RESS after vehicle key-off based at least in part on the ambient temperature and the RESS temperature;
calculating a first value of a range of the RESS, based at least in part on the expected degradation, if warming of the RESS is not implemented during vehicle key-off;
calculating a second value of the range of the RESS based on a modified value of expected degradation if warming of the RESS is implemented during vehicle key-off; and
taking an action based at least in part on the first value of the range and the second value of the range.

Abstract
Methods and systems are provided for vehicles having a rechargeable energy storage system (RESS). A first sensor is configured to measure an ambient temperature for the vehicle. A second sensor is configured to measure a temperature of the RESS. The processor is coupled to the first sensor and the second sensor, and is configured to at least facilitate taking an action based on an expected degradation of the RESS after vehicle key-off based at least in part on the ambient temperature and the RESS temperature.

20. A vehicle comprising:
-
a drive system comprising a rechargeable energy storage system (RESS); and a control system comprising; a first sensor configured to measure an ambient temperature for the vehicle; a second sensor configured to measure a temperature of the RESS; and a processor coupled to the first sensor and the second sensor and configured to at least facilitate; receiving an input as to a future time in which a driver is intending to initiate a beginning of a vehicle drive in which the vehicle is to be operated in a propulsion mode; estimating an expected degradation of the RESS after vehicle key-off for the future time based at least in part on the ambient temperature and the RESS temperature; and taking an action if the expected degradation for the future time is greater than a predetermined threshold.
