A METHOD FOR CONTROLLING A STATE OF CHARGE OF A PLUG-IN HYBRID VEHICLE

摘要

The invention relates to a method for controlling a state of charge of an electrical storage system (22) of a plug-in hybrid electric vehicle (1). The method comprises the steps of: • - determining a minimum state of charge (430, 430'), at end of a charging period (404, 404') at a next coming charging station (101, 102, 103), required for traveling a planned driving route coming after the next coming charging station (101, 102, 103); • - calculating expected increase in state of charge during the charging period (404, 404') at the next coming charging station (101, 102, 103); and • - calculating a target state of charge (420, 420') at arrival at the next coming charging station (101, 102, 103). The invention further relates to a control system configured to execute the inventive method.
