Title:
CHARGING DEVICE FOR ELECTROMOTIVE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/004647
Kind Code:
A3
Abstract:
An AC-DC converter (250) converts an alternating-current voltage (vac), supplied from an external power supply (500), to a direct-current voltage higher than a peak voltage of the alternating-current voltage, and outputs the direct-current voltage to a first power supply line (PL1). In a normal control mode, a DC-DC converter (210) steps down a voltage of the power supply line (PL1) through on/off control over a switching element (Ql) to charge a main battery (10). On the other hand, in an upper arm ON control mode, the DC-DC converter (210) charge the main battery (10) while the switching element (Ql) is kept in an on state. On the basis of a state of external charging, a control device (300) applies the upper arm ON control mode when a condition that upper arm ON control is applicable is satisfied, and applies the normal control mode when the condition is not satisfied.
