Abstract
A vehicle includes a traction battery having cells and at least one controller. The controller is programmed to charge and discharge the traction battery according to a net current for the traction battery derived from sets of temperature-based current values, each of the sets corresponding to a different one of the cells, and each of the values for a given one of the sets corresponding to a different zone of the cell.

A vehicle comprising:
- a traction battery including cells;
- and
- at least one controller programmed to charge and discharge the traction battery according to a net current for the traction battery derived from sets of temperature-based current values, each of the sets corresponding to a different one of the cells, and each of the values for a given one of the sets corresponding to a different zone of the cell.
A method for controlling an electrified powertrain comprising:
- charging and discharging a traction battery according to a net current for the traction battery derived from sets of temperature-based current values, each of the sets corresponding to a different cell of the traction battery, and each of the values for a given one of the sets corresponding to a different zone of the cell.
A vehicle comprising:
- a traction battery including cells each having first, second, and third zones;
- and
- at least one controller programmed to, for each of the cells, output currents for the second and third zones that are based on a voltage of the first zone and temperatures of the second and third zones.
