Title:
IN-VEHICLE CHARGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/032767
Kind Code:
A1
Abstract:
Provided is an in-vehicle charging apparatus, whereby an offset error generated in a sensor circuit and the like can be accurately grasped, and a current value or a voltage value outputted from the charging apparatus can be accurately recognized.
At the time of acquiring non-driven period current value information for the purpose of calculating offset information, since unsuitable non-driven period current value information is rejected by means of correct detection value information specifying processing (S14) in an in-vehicle charging apparatus (12), even if a part of the information is affected by electrical disturbance, the offset information (Aave) calculated on the basis of the correct information is permitted to be information that accurately indicates an offset error generated in an operational amplifier and the like.
