The invention discloses an emergency power supply method, system and device for a power supply unit, a storage medium and a train, belongs to the field of emergency power supply of power supply units, and is used for enabling the power supply unit to perform emergency power supply on the train. In the scheme, if an emergency traction instruction is also received when an emergency air conditioner instruction is received, a traction system is controlled to be normally started; when the air conditioner is started in a variable frequency mode, the power supply current output to the air conditioner by the power supply unit is smaller than the normal starting current of the air conditioner, and the sum of the power supply current of the air conditioner and the power supply current output to the traction system by the power supply unit is smaller than the maximum power supply current of the power supply unit. Therefore, normal running of the train is guaranteed when the power supply unit supplies power emergently, the air conditioner can be started, good riding experience of passengers is guaranteed, and normal work of the power supply unit is guaranteed.

    本发明公开了一种供电单元应急供电方法、系统、装置、存储介质及列车,属于供电单元应急供电领域,用于使供电单元为列车进行应急供电,该方案中,如果在接收到应急空调指令时同样已经接收到应急牵引指令,则控制牵引系统正常启动,并控制空调变频启动,又由于空调变频启动时供电单元输出至空调的供电电流小于空调的正常启动电流,且空调的供电电流和供电单元输出至牵引系统的供电电流之和小于供电单元的最大供电电流,从而在保证供电单元应急供电时保证列车正常行驶之外,空调还可以启动,保证乘客良好的乘车体验,且保证了供电单元的正常工作。
