Abstract

The invention discloses an emergency power supply method, device and system. The method comprises the following steps: judging whether an AC power grid for supplying power to an electricity consumption system is cut off; if the AC power grid is cut off, controlling a master emergency power supply module to start to supply power to the electricity consumption system; after controlling the master emergency power supply module to start to supply power to the electricity consumption system, judging whether a first slave emergency power supply module meets a first starting condition, wherein the first slave emergency power supply module comprises a power battery arranged on a first electric automobile; and if the first slave emergency power supply module meets the first starting condition, controlling the first slave emergency power supply module to start to supply power to the electricity consumption system. Through the method, the problem of unstable power supply caused when the power battery of the electric automobile serves as the emergency power supply in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of electric power, in particular to an emergency power supply method, device and system. Background technique [0002] When an electric vehicle is parked in a place, it is usually connected to a power system in the place to charge the electric vehicle. In important places where electricity is used, conventional emergency power supplies are often configured to provide emergency power supplies in case of power outages and other emergencies. [0003] In recent years, scholars from various countries have studied the power battery of electric vehicles as an emergency power supply, and proposed an optimal distribution method for electric vehicles to participate in emergency power supply of urban power grids as mobile power sources, but this scheme can only use electric vehicles as emergency power supplies, and The power of electric vehicles is not fixed, and the mobility of electric vehicles is high, and they may d...
