Title:
CHARGING DEVICE AND CHARGING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/226364
Kind Code:
A1
Abstract:
The present application provides a charging device and a charging control method, which are used for effectively reducing circuit costs of the charging device and effectively simplifying the control flow of series connection or parallel connection between multiple outputs of a power converter by using fewer relays in the case of increasing the output voltage range and output power of the power converter. The device comprises a first power converter, a first relay, and a second relay, wherein the first power converter comprises a first output end and a second output end. The plurality of output ends of the first power converter can be controlled to be connected in series or in parallel by controlling the on/off state of the first relay and the second relay.
