Abstract
A vehicle includes a traction battery, and a controller configured to, responsive to a transition from deplete mode to sustain mode during a first drive cycle, maintain a state of charge (SOC) of the battery within a range defined by a first maximum threshold, and responsive to initiation of a next drive cycle in the sustain mode, maintain the SOC within a range defined by a second maximum threshold greater than the first.
Claims10
A vehicle comprising:
- a traction battery;
- and
- a controller configured to,
- responsive to a transition from deplete mode to sustain mode during a first drive cycle, maintain a state of charge (SOC) of the battery within a range defined by a first maximum threshold,
- responsive to initiation of a next drive cycle in the sustain mode and a temperature being greater than a threshold, maintain the SOC within a range defined by a second maximum threshold greater than the first maximum threshold, and
- responsive to initiation of the next drive cycle in the sustain mode and the temperature being less than the threshold, maintain the SOC within the range defined by the first maximum threshold.
