Abstract

When it is determined that an electric storage (B) is to be charged from a commercial power source (55), a controller (60) sets a control target of a voltage VH of a power line (PL2) to be controlled by a boost converter (10), based on a voltage Vac of the commercial power source (55). Specifically, the controller (60) sets the control target of the voltage VH to a level approximately equal to the crest value of voltage Vac. Then, the controller (60) outputs an input permission command (EN) to a relay circuit (40), and controls inverters (20, 30) to execute charging of the electric storage (B).

Description

technical field [0001] The invention relates to a charge control device and an electric vehicle. Specifically, the present invention relates to charge control of a power storage device mounted on an electric vehicle such as an electric vehicle or a hybrid vehicle. Background technique [0002] Japanese Patent Laid-Open No. 04-295202 discloses a motor drive and power processing device used in electric vehicles. This motor drive and power processing device includes a secondary battery, inverters IA and IB, induction motors MA and MB, and a control unit. The induction motors MA and MB respectively comprise Y-connected windings CA and CB, and input / output ports are connected to neutral points NA and NB of the windings CA and CB through EMI filters. [0003] Inverters IA and IB are provided corresponding to induction motors MA and MB, respectively, and are connected to windings CA and CB, respectively. Inverters IA and IB are connected in parallel to the secondary battery. ...
