The invention discloses an electric locomotive as well as a power supply system and a control method thereof. The power supply system further comprises a traction storage battery pack, a first control switch, a bidirectional charger and a second control switch, the traction storage battery pack is connected with a control load through a first control switch, the first control switch is a manual switch, and the control load comprises charger control equipment; the traction storage battery pack is further connected with the bidirectional charger through a second control switch, and the bidirectional charger is connected with the auxiliary power supply device and different loads. According to the invention, a control storage battery and a charger thereof are cancelled, and the traction storage battery pack or the overhead line system electric energy converted by the bidirectional charger supplies power to the control load; the problems that the use scene is limited due to the fact that a control storage battery cannot achieve the functions of traction self-walking, skylight period power supply and the like, and the space of a machine room is occupied due to the fact that a traction storage battery pack is additionally arranged are solved.
本发明公开了一种电力机车及其供电系统与控制方法,所述供电系统还包括牵引蓄电池组、第一控制开关、双向充电机以及第二控制开关;所述牵引蓄电池组通过第一控制开关与控制负载连接,所述第一控制开关为手动开关,所述控制负载包括充电机控制设备;所述牵引蓄电池组还通过第二控制开关与所述双向充电机连接,所述双向充电机与所述辅助供电装置、不同负载连接。本发明取消了控制蓄电池及其充电机,由牵引蓄电池组或经双向充电机转换后的接触网电能给控制负载供电,解决了控制蓄电池无法实现牵引自行走、天窗期供电等功能导致的使用场景受限以及额外增加牵引蓄电池组导致机械间空间被占用的问题。
