Document Type and Number:
WIPO Patent Application WO/2020/052142
Kind Code:
A1
Abstract:
The present application relates to a charging device and a charging system, wherein the charging device comprises: a direct current bus access terminal, which is used for electrically connecting to a direct current bus so that the charging device is electrically connected to the direct current bus; a load access terminal, which is used for electrically connecting to a load to be charged so that the charging device is electrically connected to the load to be charged; a charging circuit, an input terminal thereof being electrically connected to the direct current bus access terminal and an output terminal thereof being electrically connected to the load access terminal so that the electrical energy of the direct current bus charges the load to be charged; a control circuit, which is electrically connected to the charging circuit and which is used for controlling the charging circuit to complete a charging process. In the charging device provided by the present application, by means of configuring the control circuit to control the charging circuit to use the electrical energy of the direct current bus to charge the load to be charged, and by independently configuring the charging circuit as a charging device, a plurality of direct current bus voltage classes may be compatible such that a capacitive direct current load hot accesses a direct current micro network.
