The invention discloses a method for controlling charging of a railway vehicle, a line charging system and the railway vehicle. When the vehicle is charged, the line charging system is in wireless communication with the vehicle-mounted charging system, and a charger of the line charging system is electrically connected with a power battery of the vehicle-mounted charging system for charging. The method for controlling vehicle charging comprises the steps that charging interaction information sent by a vehicle-mounted charging system is acquired; determining that the wireless communication with the vehicle-mounted charging system is abnormal according to the charging interaction information; the charger is controlled to charge the power battery at a preset current value, and the preset current value is smaller than the charging current demand value of the power battery. According to the method for controlling charging of the vehicle, the charger can still continuously output electric energy at the preset current value after wireless communication fails, the problem of charging failure caused by the wireless communication failure is effectively avoided, the fault tolerance rate is increased, and the charging efficiency is improved.

    本发明公开了一种控制轨道车辆充电的方法、线路充电系统和轨道车辆。其中,当车辆充电时,线路充电系统与车载充电系统进行无线通信,线路充电系统的充电器与车载充电系统的动力电池电连接以充电。控制车辆充电的方法包括:获取车载充电系统发送的充电交互信息;根据充电交互信息确定与车载充电系统的无线通信存在异常;控制充电器以预设电流值对动力电池进行充电,其中,预设电流值小于动力电池的充电电流需求值。该控制车辆充电的方法实现了无线通信失效后充电器依然可以以预设电流值持续输出电能,有效规避无线通信失效导致的充电失败问题,提升故障容错率,提高了充电效率。
