1. A system control module configured to modify a vehicle performance to extend the life of a battery based on a predicted state of health profile of the battery from a state of health system, the predicted state of health system comprising:
a vehicle route profile generator arranged to generate a vehicle specific route profile based on historical vehicle driving information;
a powertrain model arranged to convert the vehicle specific route profile to a predicted battery demand profile;
a system-to-cell converter arranged to receive the predicted battery demand profile and convert the battery demand profile to a cell-level operating profile;
a remaining useful life estimator arranged to receive the cell-level operating profile and generate a remaining useful life of the battery estimate based on the cell-level operating profile; and
a state of health profile generator arranged to generate the predicted state of health profile of the battery based on based on the remaining useful life of the battery estimate;
wherein the system control module causes a vehicle performance manager to issue a command to the vehicle to modify a powertrain performance characteristic of the vehicle in dependence on the predicted state of health profile.
