Abstract
A vehicle includes an engine block heater, a traction battery, and a controller. The controller, responsive to a temperature being less than a threshold, charges the traction battery with grid energy until a state of charge of the traction battery achieves a charge target. The controller is further programmed to, responsive to the state of charge achieving the target, discharge the traction battery to power the engine block heater until the state of charge falls below a discharge target or the temperature achieves a temperature target. The controller is also programmed to, responsive to the charge falling below the discharge target, charge the traction battery with grid energy until the state of charge achieves the charge target. Additionally, the controller is programmed to, responsive to a temperature achieving a temperature target, inhibit charging and discharging the traction battery.
