Abstract

The invention discloses a railway vehicle, a charging system thereof and a charging control device and method. The charging control device comprises a current taking device, a switch circuit and a controller, wherein the current taking device is used for being connected with a charging device arranged at a charging station when the railway vehicle parks at the charging station, one end of the switch circuit is connected with a power battery of the railway vehicle, the other end of the switch circuit is connected with the current taking device, the switch circuit comprises a first switch assembly and second switch assembly, the controller is connected with the first switch assembly and the second switch assembly and is used for controlling the first switch assembly or the second switch assembly to be switched on according to a connection relation between the current taking device and the charging device so that the polarity of a charging interface of the charging device is maintained consistent with the polarity of a positive electrode and a negative electrode of the power battery during charging of the power battery. Therefore, the phenomenon of charging by mistake during driving of the railway vehicle in different directions can be prevented, and the charging reliability of the railway vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a charging control device for a rail vehicle, a rail vehicle, a charging system for a rail vehicle, and a charging control method for a rail vehicle. Background technique [0002] In general, vehicles that require power batteries to provide energy, such as rail vehicles, etc., need to control the vehicle to drive to the charging station for charging if the power battery needs to be charged when driving on the road. However, since the direction in which the vehicle arrives at the charging station is not fixed, for example, for an east-west charging station, when the vehicle arrives at the charging station, the driving direction may be from west to east or from east to west, so when charging Positive and negative charging may be reversed, which may cause damage to the power battery and affect the safety of the vehicle. Contents of the invention [0003] The present inventi...
