Title:
AUXILIARY POWER SUPPLY MANAGEMENT SYSTEM AND METHOD, AND RAILWAY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/005078
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an auxiliary power supply management system and method, and a railway vehicle. The auxiliary power supply management system comprises a control module, a plurality of power supply management modules and a plurality of first switches, wherein the plurality of power supply management modules are sequentially arranged on a power supply bus, and one first switch is arranged between two adjacent power supply management modules; when it is detected that the auxiliary power supply management system meets a preset start condition, the control module controls the first switches to be in a switched-on state, and sequentially sends grid connection instructions to power supply management units according to a polling sequence; and if a grid connection success signal fed back by a target power supply management unit is received, the control module stops sending the grid connection instructions to power supply management units that are about to receive; and when it is detected that a power supply bus is powered on, the power supply management units that are about to receive control corresponding second switches to be in the switched-on state. By means of the auxiliary power supply management system provided in the present application, the time for time-divisional starting and grid connection of power supply management modules is shortened, thereby improving the running efficiency of a railway vehicle.
