Title:
ELECTRIC CAR, MULTI-FUNCTIONAL IN-VEHICLE CHARGER OF ELECTRIC CAR, AND CONTROL METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/019148
Kind Code:
A1
Abstract:
An electric car (200), multi-functional in-vehicle charger (100) of an electric car, and control method for same. The multi-functional in-vehicle charger (100) comprises: a bi-directional AC/DC conversion circuit (10), a first DC/DC conversion circuit (20), a second DC/DC conversion circuit (30), a sampling circuit (40), and a control module (50). The sampling circuit (40) is used to separately sample the voltage and current of a utility grid, the voltage at a direct current end of the bi-directional AC/DC conversion circuit (10), the voltage and current of a power battery, and the voltage and current of a low-voltage battery. The control module (50) is used to control, according to sampling results of the sampling circuit (40), the bi-directional AC/DC conversion circuit (10), the first DC/DC conversion circuit (20), and the second DC/DC conversion circuit (30), thus realizing any of the functions of power battery charging, low-voltage battery charging, alternating current inversion of the power battery, alternating current inversion of the low-voltage battery, and providing a low-voltage output with a load capacity using the power battery.
