Patent ID: 8368354

Claim:
A charge control device for a vehicle configured such that a rechargeable power storage device mounted on the vehicle can be charged by a power supply outside the vehicle, comprising: a charger configured to convert electric power supplied from said power supply in voltage to charge said power storage device; a current detection unit configured to detect a current input to said power storage device to output a first detection value having a first resolution and a second detection value having a second resolution higher than said first resolution; and a control device controlling said charger based on said first and second detection values, a range of said first detection value being wider than the range of said second detection value, and a detection cycle of said first detection value being shorter than the detection cycle of said second detection value, said control device including a protection control unit controlling, when charging power calculated using said first detection value exceeds a predetermined limit value, said charger to reduce said charging power, and a full charge control unit controlling said charger such that said power storage device attains a predetermined fully charged state, based on charging power calculated using said second detection value.
