Abstract

The invention discloses a train storage battery traction system. The system comprises a controller, a first switch, a second switch, a first traction converter and a first 110V storage battery. The first 110V storage battery is connected with a direct current 110V bus through the first switch. The first 110V storage battery is connected with the first traction converter through the second switch.The controller is used for controlling the first switch to be turned on and the second switch to be turned off when confirming that a first pantograph ascends and further used for controlling the first switch to be turned off and the second switch to be turned on when confirming that the first pantograph descends. By the utilization of the system, hardware resources can be saved, the occupied space is reduced, and cost is saved. The invention further provides a train storage battery traction method and a train.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a train storage battery traction system, a method and a train. Background technique [0002] In the prior art, the subway includes a 110V battery and a 220V battery, and electric energy is obtained from a DC 110V bus and a DC 220V bus respectively. Among them, the 110V battery is used to supply power for the control circuit on the subway, such as lighting system, control system, etc., and the 220V battery is used to provide power for the traction motor. [0003] However, in the actual use of the subway, the probability of using the battery for traction and power supply is very small. In this way, it is a waste of hardware resources and power supply energy to equip each subway with a 220V battery. It takes up more space on the subway. [0004] Therefore, the subway in the prior art is equipped with two batteries of different specifications, which wastes resources and cos...
