Title:
ELECTRICALLY DRIVEN VEHICLE AND METHOD OF CONTROLLING CHARGING THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/011176
Kind Code:
A1
Abstract:
A charger (200) charges a main battery (10) via a power conversion route that goes through an insulating transformer (260), and whereby an external power supply (400) and the main battery (10) are electrically insulated, when a first relay (RL1) and a second relay (RL2) are turned off and a third relay (RL3) is turned on. Meanwhile, the charger (200) charges the main battery (10) via a power conversion route that bypasses the insulating transformer (260), and whereby the external power supply (400) and the main battery (10) are electrically connected, when the first relay (RL1) and the second relay (RL2) are turned off and the third relay (RL3) is turned on. As a result, either an external charging wherein insulation performance is secured with the insulating transformer (260), or an external charging wherein the insulating transformer (260) is bypassed and high efficiency is prioritized can be applied selectively for the charger (200), with an ON-OFF control of the relays (RL1-RL3).
