1. A method for determining a minimum state of charge for a traction battery of a vehicle, the method comprising:
a controller determining a routine use of charge of the traction battery, wherein determining the routine use of charge of the traction battery comprises determining a routine usage of user-selectable energy consuming vehicle subsystems;
the controller determining a user requirement for future driving of the vehicle;
predicting a reduction in a state of charge of the traction battery associated with the user requirement based at least in part on the determined routine use of charge of the traction battery;
the controller determining the minimum state of charge for the traction battery for enabling the user requirement to be satisfied based at least in part on the predicted reduction in the state of charge of the traction battery; and
the controller providing an output to a user indicative of a time requirement for increasing the state of charge of the traction battery to a value at or above the determined minimum state of charge for the traction battery;
wherein the output is user-selectable, enabling charging of the traction battery to the corresponding value to be performed when selected.
