Title:
VEHICLE
Document Type and Number:
Japanese Patent JP2015220825
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable a quicker determination of completion of a pre-charge even when a current sensor used for detecting a battery current is abnormal.SOLUTION: When a battery current sensor is normal, a completion of a pre-charge of a capacitor is determined by using a battery current Ib obtained from the battery current sensor and a voltage difference ΔV between a battery voltage Vb obtained from the battery voltage sensor and a capacitor voltage VH obtained from a capacitor voltage sensor (S140, S150). Further, when the battery current sensor is abnormal but a reactor current sensor is normal, a completion of a pre-charge of a capacitor is determined by using the voltage difference ΔV and a reactor current IL obtained from the reactor current sensor (S160, S170).
