Plug-in vehicle eco charging mode

摘要

A system for controlling battery charging in a vehicle includes a traction battery and a controller. The controller is configured to charge the traction battery to a SOC that is less than a maximum SOC based on an amount of charge predicted to be received from an anticipated regenerative braking event. The regenerative braking event is anticipated to occur during the next drive cycle. The target SOC may be set such that, upon occurrence of the anticipated regenerative braking event, the traction battery achieves the maximum SOC.

1. A vehicle comprising:
a fraction battery; and a controller configured to cause the traction battery to be charged to a target state of charge (SOC) less than a maximum SOC based on an amount of charge predicted to be received from an anticipated regenerative braking event during a next drive cycle such that upon occurrence of the anticipated regenerative braking event, the traction battery achieves approximately maximum SOC, the predicted regenerative charge being based on a difference between regenerative energy produced and regenerative energy captured during a previous drive cycle exceeding a calibrated threshold.
