Title:
CHARGING APPARATUS AND CONTROL METHOD THEREFOR, AND RAIL VEHICLE CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/020326
Kind Code:
A1
Abstract:
A charging apparatus (100), comprising a charger (10), a current supply apparatus (20), a first switch circuit (30) and a controller (40). The charger (10) is used for providing a rail vehicle with electrical energy required for charging, the current supply apparatus (20) is used for connecting a current collector of the rail vehicle when the rail vehicle is charging, one end of the first switch circuit (30) is connected to the charger (10), another end of the first switch circuit (30) is connected to the current supply apparatus (20), the first switch circuit (30) comprises a first switch assembly (31) and a second switch assembly (32), the controller (40) is respectively connected to the first switch assembly (31) and the second switch assembly (32), and the controller (40) is used for obtaining a driving direction of the rail vehicle and, according to the driving direction, controlling the first switch assembly (31) to close, or controlling the second switch assembly (32) to close, so that the polarity of the charger (10) is consistent with the polarity of the current collector. The charging apparatus increases the reliability of the rail vehicle charging, without it being necessary to alter the structure of the rail vehicle. Also provided are a rail vehicle charging system, and a control method for the charging apparatus.
