CONTROL APPARATUS FOR PLUG-IN HYBRID VEHICLE, AND CONTROL METHOD FOR THE SAME

摘要

A control apparatus for a plug-in hybrid vehicle having a secondary battery that can be charged with external power includes a stoppage period acquisition unit and a battery control unit. The stoppage period acquisition unit obtains an engine stoppage period in which an internal combustion engine is stopped. The battery control unit controls charging/discharging of the secondary battery. The battery control unit sets an upper limit value of a storage amount of the secondary battery to be lower when the engine stoppage period equals or exceeds a predetermined period than when the engine stoppage period is shorter than the predetermined period.
