Abstract
Methods and systems for a vehicle such as a plug-in hybrid electric vehicle (PHEV) having a traction battery are for improving the drivability of the vehicle the battery has low discharge limits. The battery may have such low discharge limits due to the battery being cold and/or the battery state-of-charge (SOC) being low. In operation, upon the battery having a discharge limit lower than a threshold while the vehicle is operating in a charge sustain mode, the engine of the vehicle is used to charge the battery to increase the SOC of the battery such that the battery has a discharge limit greater than the threshold. The vehicle is operated in the charge sustain mode using the battery with the increased SOC.
