Title:
CHARGING APPARATUS AND CONTROL METHOD THEREFOR, AND ELECTRICAL DEVICE AND POWER SUPPLY SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/065801
Kind Code:
A1
Abstract:
The embodiments of the present application provide a charging apparatus and a control method therefor, and an electrical device and a power supply system thereof. The charging apparatus is applied to the electrical device, the electrical device comprises a charging port and a power battery, and the charging port is used for being electrically connected to an external charging device, wherein: a first port of the charging apparatus is electrically connected to the charging port; a second port of the charging apparatus is electrically connected to the power battery; a third port of the charging apparatus is electrically connected to a first load; and the charging apparatus is used for converting electrical energy inputted by the charging port or the power battery into a first alternating current, and for transmitting the first alternating current to the first load. The embodiments of the present application use the charging apparatus for directly converting, into a first alternating current, electrical energy having a relatively high voltage and inputted by the charging port or the power battery, thereby ensuring that the first alternating current has relatively high power-supply power. Moreover, insofar as the current value of the first alternating current is relatively low, the first alternating current loses relatively little electrical energy on a transmission line, thereby reducing electrical energy losses on transmission lines.
